technical field

The present application relates to the technical field of terminals, and in particular to a video shooting method and electronic equipment.

Background technique

Currently, electronic devices such as mobile phones can provide not only a picture shooting function, but also a video shooting function. The electronic device adopts the video shooting function, and can start a camera to record video.

However, in scenes with multiple subjects such as gatherings, parent-child interaction, etc., if the above-mentioned video shooting function is used, it is very likely that multiple subjects cannot be framed together at the same time. Or, in concerts and other event sites, there is a need to shoot distant and close shots at the same time. If the above video shooting function is used, it may not be able to meet the various shooting needs of users at the same time.

It can be seen that there is an urgent need for a video shooting solution to flexibly adapt to various scenes requiring video shooting. On this basis, there is still a lack of a solution that can reasonably control the size of video files in various shooting scenarios.

Contents of the invention

Embodiments of the present application provide a video shooting method and an electronic device, which can control the size of a video file by adjusting the capture parameters of a camera or controlling switching of shooting modes.

In order to achieve the above object, the embodiments of the present application adopt the following technical solutions:

In a first aspect, the embodiment of the present application provides a video shooting method, which can be applied to electronic devices such as mobile phones and tablets that support video shooting. Wherein, the electronic device displays a first interface, the first interface is a viewfinder interface for video recording by the electronic device, and the first interface includes a first preview image collected by the first camera with the first collection parameters. The first preview image is displayed in full screen on the first interface; the acquisition parameters of the camera of the electronic device include frame rate and/or resolution. That is to say, the first interface is a viewfinder interface for capturing images by a single camera. When using a single camera to record video, the preview image can be collected by using a collection parameter higher than the preset parameter threshold, or the preview image can be collected by using a collection parameter lower than or equal to the preset parameter threshold. The electronic device receives a first user operation on the first interface, and the first operation is used to trigger the electronic device to switch to use the second camera and the third camera to capture images. For example, the first operation is a user's selection operation of the multi-mirror mode. The electronic device responds to the first operation, and if the first collection parameter is greater than the preset parameter threshold, the electronic device displays a second interface; the second interface is a viewfinder interface for video recording by the electronic device, and the second interface includes a second camera that collects data with the second collection parameter. The second preview image and the third preview image acquired by the third camera with the second acquisition parameters. The second acquisition parameter is smaller than the first acquisition parameter.

In summary, using the method of the embodiment of the present application, after the electronic device switches from the mode of using a single camera to capture images to the mode of using two cameras to capture images, if it detects that the capture parameters used before switching are greater than the preset parameters threshold, you can reduce the acquisition parameters after switching. For example, the preset parameter threshold is 1080p, and the resolution used before the switch is 4K, and if it is greater than the preset parameter threshold, the resolution can be reduced to 1080p after the switch. Since the size of the generated video file is approximately twice that of a single camera when two cameras are used to collect images, the above method of adjusting the acquisition parameters is beneficial to control the size of the video file and avoid generating an excessively large video file. Thereby, subsequent storage and use are convenient. In this way, the intelligence of video shooting can be improved, and the size of video files can be reasonably controlled.

In another possible design of the first aspect, the electronic device responds to the first operation, and if the first acquisition parameter is less than the preset parameter threshold, the electronic device displays a third interface; the third interface is a viewfinder interface for video recording by the electronic device , the third interface includes a fourth preview image captured by the second camera with the first capture parameters and a fifth preview image captured by the third camera with the first capture parameters.

That is to say, using the method of this embodiment, after the electronic device switches from the mode of using a single camera to capture images to the mode of using two cameras to capture images, if it is detected that the capture parameters used before the switch do not exceed the preset parameters threshold, the acquisition parameters before the switch can continue to be used after the switch. For example, the preset parameter threshold is 1080p, and the resolution adopted before switching is 1080p. If the preset parameter threshold is not exceeded, the resolution of 1080p can still be adopted after switching.

In another possible design manner of the first aspect, the first collection parameter includes a first frame rate, the second collection parameter includes a second frame rate, and the second frame rate is lower than the first frame rate. Wherein, the first acquisition parameter is greater than the preset parameter threshold, including: the first frame rate is greater than the preset frame rate threshold.

That is to say, with the method of this embodiment, the collection parameters include the frame rate. Correspondingly, in the case that the frame rate before the switching is greater than the preset frame rate threshold, the frame rate may be reduced after the switching. For example, the preset frame rate threshold is 30 frames, and the frame rate before switching is 60 frames, which is greater than the preset frame rate, then the frame rate can be adjusted to 30 frames after switching.

In another possible design manner of the first aspect, the first collection parameter includes a first resolution, the second collection parameter includes a second resolution, and the second resolution is smaller than the first resolution. Wherein, the first acquisition parameter is greater than the preset parameter threshold, including: the first resolution is greater than the preset resolution threshold.

That is to say, with the method of this embodiment, the acquisition parameters include resolution. Correspondingly, if the resolution before the switching is greater than the preset resolution threshold, the resolution may be reduced after the switching.

In another possible design of the first aspect, the first acquisition parameters include a first frame rate and a first resolution, and the second acquisition parameters include a second frame rate and a second resolution; the second frame rate is less than the first A frame rate, and/or, the second resolution is less than the first resolution. Wherein, the first acquisition parameter is greater than the preset parameter threshold, including: the first frame rate is greater than the preset frame rate threshold, and/or the first resolution is greater than the preset resolution threshold.

That is to say, with the method of this embodiment, the acquisition parameters include frame rate and resolution at the same time. Correspondingly, if at least one of the frame rate and the resolution before the switching is greater than the corresponding preset parameter threshold, after the switching, the frame rate or the resolution exceeding the preset parameter threshold needs to be lowered. For example, if the resolution is higher than the preset resolution threshold, the resolution is reduced. If the frame rate is higher than the preset frame rate threshold, the frame rate will be reduced. If the resolution is higher than the preset resolution threshold and the frame rate is higher than the preset frame rate threshold, the resolution and frame rate will be reduced at the same time.

In another possible design of the first aspect, after the electronic device displays the second interface, the electronic device receives the user's second operation on the second interface, and the second operation is used to trigger the electronic device to switch to use the fourth camera to capture image. In response to the second operation, the electronic device displays a fourth interface, the fourth interface is a viewfinder interface for video recording by the electronic device, and the fourth interface includes a sixth preview image collected by the fourth camera with the first collection parameters. The sixth preview image is displayed in the fourth interface in full screen.

That is to say, by adopting the method of this embodiment, after the collection parameter is lowered, when switching back to the mode of using a single camera to collect images again, the preview image can be collected with the first collection parameter again. For example, in the single front mode, the first acquisition parameter is 4K, if after switching to the front and rear dual mirror mode, reduce the resolution to 1080p. After that, switch to single front mode or single rear mode again to restore the resolution to 4K. In this way, the quality of the video file can be improved while controlling the size of the video file reasonably. For example, after reverting to 4K, the captured image has higher definition than the image captured at 1080p.

In another possible design manner of the first aspect, the second interface further includes first prompt information, and the first prompt information is used to prompt that the resolution and/or frame rate have been switched. For example, the first prompt message is "When using two cameras to capture images, it does not support capturing images at 4k and 60 frames"

That is to say, by using the method of this embodiment, the electronic device can explicitly prompt the user that the collection parameters have been adjusted.

In another possible design manner of the first aspect, the first interface is a viewfinder interface before the electronic device records, and the second interface is the viewfinder interface before the electronic device records. Alternatively, the first interface is a viewfinder interface where the electronic device is recording, and the second interface is a viewfinder interface where the electronic device is recording.

That is to say, by using the method of this embodiment, the electronic device can complete the intelligent adjustment of the collection parameters before or during the video recording, so as to reasonably control the size of the video file. Among them, the adjustment before recording can control the start of video recording with reasonable acquisition parameters. Adjust during the recording process, you can control each mode to acquire images with reasonable acquisition parameters.

In another possible design manner of the first aspect, in the viewfinder interface before recording, the acquisition parameters of the camera can be set. Wherein, in the mode of using a single camera to collect images, collection parameters greater than a preset parameter threshold can be set. Taking the first interface as an example, if the first interface is a viewfinder interface before video recording by the electronic device. After the electronic device displays the first interface, the electronic device may receive a third user operation on the first interface, where the third operation is used to trigger the electronic device to set the acquisition parameters. For example, a setting button is displayed on the first interface, and the third operation may be a click operation on the setting button. In response to the user's third operation on the first interface, the electronic device displays parameter options, the parameter options include a first option, the first option corresponds to a third acquisition parameter, and the third acquisition parameter is greater than a preset parameter threshold. It can be seen that, in the mode of using a single camera to collect images, the electronic device can provide collection parameters greater than the preset parameter threshold for the user to select. The electronic device receives a user's selection operation on the first option. In response to the selection operation, the electronic device sets the collection parameter as the third collection parameter.

That is to say, using the method of this embodiment, in the mode of using a single camera to collect images, the electronic device can provide collection parameters greater than the preset parameter threshold for the user to choose and set, so that a higher resolution and/or frame can be set. rate to improve the quality of the video file.

In another possible design manner of the first aspect, in the viewfinder interface before recording, the acquisition parameters of the camera can be set. Wherein, in the mode of using two cameras to collect images, the collection parameters larger than the preset parameter threshold cannot be set. Taking the second interface as an example, the second interface is a viewfinder interface before video recording by the electronic device. After the electronic device displays the second interface, the electronic device receives a third operation performed by the user on the second interface, and the third operation is used to trigger the electronic device to set collection parameters. In response to the user's third operation on the second interface, the electronic device displays parameter options, where the first option is not included in the parameter options, or the first option is in an unselectable state.

That is to say, with the method of this embodiment, in the mode of using a single camera to collect images, the electronic device does not provide optional collection parameters greater than the preset parameter threshold for the user to select and set. Therefore, it may be prohibited to set a higher resolution and/or frame rate in the mode of using two cameras to capture images, so as to reasonably control the size of the video file.

In a second aspect, the embodiment of the present application provides a video shooting method, which can be applied to electronic devices such as mobile phones and tablets that support video shooting. Among them, in the horizontal screen state and in the process of recording, as the user switches the left and right hands to hold the electronic device, the electronic device can change the layout of the interface elements to avoid the user's fingers pointing to the mirror. This method can be applied to various multi-mirror modes. The solution of this application will be described below using only the second interface in the aforementioned first aspect and any of its possible implementations. In actual implementation, the second interface can be replaced by a horizontal In the screen state, the viewfinder interface that is recording in any multi-mirror mode.

Taking the second interface as an example, the second interface is a viewfinder interface where the electronic device is recording. The second interface includes a first control and a second control. The first control is used to indicate the recording mode currently adopted by the electronic device (i.e. the multi-mirror mode). , such as front and rear dual-mirror mode, picture-in-picture mode, etc.), and for triggering electronic equipment to switch recording modes. The second control is used to trigger the electronic device to switch the rear camera, for example, the second control is a zoom bar. In the horizontal screen state, if the electronic device detects that the electronic device is in the first holding state, that is, the right hand holding state, for example, the bottom of the electronic device is close to the user's right hand state, the electronic device will be in the first holding state of the screen of the electronic device. A first control is displayed in one area, and a second control is displayed in a second area of the screen. The first area is an area located at the top edge of the screen and close to the right edge of the screen in the landscape state, and the second area is an area located at the bottom edge of the screen and close to the left edge of the screen in the landscape state. That is to say, when the right hand is holding it, the first control is displayed on the screen at a position convenient for the thumb of the right hand to operate, and the second control is displayed at a position convenient for operation without holding the top of the electronic device with the left hand. In the horizontal screen state, if the electronic device detects that the electronic device is in the second holding state, that is, the state of holding the electronic device with the left hand, for example, the bottom of the electronic device is close to the user's left hand state, the electronic device will display in the third area of the screen The first control displays the second control in the fourth area of the screen. The third area is an area located at the top edge of the screen and close to the left edge of the screen in the landscape state; the fourth area is an area located at the bottom edge of the screen and close to the right edge of the screen in the landscape state. That is to say, when the left hand holds the electronic device, the first control is displayed on the screen at a position convenient for thumb operation of the left hand, and the second control is displayed at a position convenient for operation without holding the top of the electronic device with the right hand.

To sum up, using the method of the embodiment of the present application, the electronic device can change the layout of the interface elements when the electronic device is in the horizontal screen state and is in the process of recording, as the user switches the left and right hands to hold the electronic device. Under the premise, complete the operation. In this way, the quality of the captured video can be improved.

In another possible design manner of the second aspect, the second interface further includes a third control, and the third control is used to trigger the electronic device to switch the speed of playing the recorded video. In the horizontal screen state, if the electronic device detects that the electronic device is in the first holding state, the electronic device displays the third control in the first area. That is to say, when the right hand is holding it, the third control is displayed on the screen at a position convenient for the thumb of the right hand to switch the speed of playing the video. In the horizontal screen state, if the electronic device detects that the electronic device is in the second holding state, the electronic device displays a third control in the third area. That is to say, when the left hand is holding the device, the third control is displayed on the screen at a position convenient for the thumb of the left hand to switch the speed of playing the video.

In another possible design manner of the second aspect, the second interface further includes a fourth control, and the fourth control is used to trigger the electronic device to set a flash. In the horizontal screen state, if the electronic device detects that the electronic device is in the first holding state, the electronic device displays a fourth control in the first area. In the horizontal screen state, if the electronic device detects that the electronic device is in the second holding state, the electronic device displays a fourth control in the third area.

In another possible design manner of the second aspect, the second interface includes recording timing. In the horizontal screen state, if the electronic device detects that the electronic device is in the first holding state, the electronic device displays the recording timing in the fifth area of the screen. The fifth area is an area near the intersection of the upper edge of the screen and the left edge of the screen in the horizontal screen state. In the horizontal screen state, if the electronic device detects that the electronic device is in the second holding state, the electronic device displays the recording timing in the sixth area of the screen. The sixth area is an area located near the intersection of the upper edge of the screen and the right edge of the screen in the horizontal screen state.

That is to say, by adopting the method of this embodiment, the recording timing is displayed at the upper corner away from the hand currently holding the electronic device, which is convenient for the user to view.

In another possible design of the second aspect, the second preview image is displayed in the first window of the second interface, the third preview image is displayed in the second window of the second interface, and the first window is a full-screen window , the second window is inside the first window. That is, the second interface is a viewfinder interface in the picture-in-picture mode. In the landscape state, if the electronic device detects that the electronic device is in the first holding state, the electronic device displays the second window below the fifth area. In the horizontal screen state, if the electronic device detects that the electronic device is in the second holding state, the electronic device displays the second window below the sixth area.

That is to say, compared with directly displaying the small window at the top corner of the screen in the vertical screen state, using the method of this embodiment to display the small window under the recording timing can avoid blocking the timing.

In another possible design manner of the second aspect, the electronic device may detect the state of the electronic device through a gravity sensor or an antenna. For example, the gravity sensor can detect the flip change of the electronic device, and the reflection coefficient of the antenna of the electronic device can reflect the holding state of the electronic device. In this way, the electronic device can accurately detect that the electronic device is currently in the first holding state or the second holding state.

In a third aspect, the embodiment of the present application provides a video shooting method, which can be applied to electronic devices such as mobile phones and tablets that support video shooting. Wherein, the electronic device displays a first interface, the first interface is a viewfinder interface before video recording by the electronic device, the first interface includes a first preview image collected by the first camera with the first acquisition parameters, and the first preview image is displayed in full screen on the first In the interface; the acquisition parameters of the camera of the electronic device include frame rate and/or resolution. That is to say, the first interface is a viewfinder interface for capturing images using a single camera. When using a single camera to record video, the preview image can be collected by using a collection parameter higher than the preset parameter threshold, or the preview image can be collected by using a collection parameter lower than or equal to the preset parameter threshold. The electronic device receives a user's first operation on the first interface, and the first operation is used to trigger the electronic device to start video recording. In response to the first operation, the electronic device displays a second interface if the first collection parameter is less than a preset parameter threshold. The second interface is the viewfinder interface where the electronic device is recording. The second interface includes the second preview image collected by the first camera with the first acquisition parameters and the first control in an operable state. The first control is used to trigger the electronic device. Switch the recording mode (i.e. multi-mirror mode), the recording mode includes the mode of using two cameras to collect images. That is to say, after starting video recording in the mode of using a single camera to collect images, if the collection parameter is less than the preset parameter threshold, an operable first control is provided in the video viewfinder interface, that is, in this case, it is allowed to switch to using The mode in which the two cameras capture images. In response to the first operation, if the first collection parameter is greater than the preset parameter threshold, the electronic device displays a third interface; the third interface is a viewfinder interface where the electronic device is recording, and the third interface includes a second preview image, and the third interface The interface does not include the first control in an operable state. That is to say, after starting to record in the mode of using a single camera to capture images, if the capture parameter is greater than the preset parameter threshold, no operable first control will be provided in the viewfinder interface that is recording, and in this case it is not allowed to switch to Mode for capturing images using two cameras.

In summary, using the method of the embodiment of the present application, in the process of video recording, only when the acquisition parameter is less than the preset parameter threshold, the electronic device is allowed to switch to the mode of using two cameras to acquire images; and when the acquisition parameter is greater than When the parameter threshold is preset, it is not allowed to switch to the mode of acquiring images with two cameras. In this way, the size of the video file can be reasonably controlled.

In another possible design manner of the third aspect, the first collection parameter includes a first frame rate. Wherein, the first acquisition parameter is greater than the preset parameter threshold, including: the first frame rate is greater than the preset frame rate threshold; the first acquisition parameter is less than the preset parameter threshold, includes: the first frame rate is less than the preset frame rate threshold.

That is to say, with the method of this embodiment, the collection parameters include the frame rate. Correspondingly, in a case where the frame rate when using a single camera to capture images is greater than the preset frame rate threshold, switching to the mode of using two cameras to capture images is not allowed.

In another possible design manner of the third aspect, the first collection parameter includes a first resolution. Wherein, the first acquisition parameter being greater than the preset parameter threshold includes: the first resolution is greater than the preset resolution threshold; the first acquisition parameter is less than the preset parameter threshold includes: the first resolution is less than the preset resolution threshold.

That is to say, with the method of this embodiment, the acquisition parameters include resolution. Correspondingly, in a case where the resolution of images captured by a single camera is greater than the preset resolution threshold, switching to the mode of capturing images by using two cameras is not allowed.

In another possible design manner of the third aspect, the first acquisition parameters include a first frame rate and a first resolution. Wherein, the first acquisition parameter is greater than the preset parameter threshold, including: the first frame rate is greater than the preset frame rate threshold, and/or the first resolution is greater than the preset resolution threshold; the first acquisition parameter is less than the preset parameter threshold, It includes: the first frame rate is less than the preset frame rate threshold, and the first resolution is less than the preset resolution threshold.

That is to say, with the method of this embodiment, the acquisition parameters include frame rate and resolution at the same time. Correspondingly, if at least one of the frame rate and the resolution before the switching is greater than the corresponding preset parameter threshold, the switching is not allowed. And only when both are smaller than the corresponding preset parameter threshold, switching is allowed.

In another possible design of the third aspect, after the electronic device displays the second interface, the electronic device receives the user's second operation on the first control in the operable state, and the second operation is used to trigger switching of the electronic device recording mode. In response to the user's second operation on the first control in the operable state, the electronic device displays mode options on the second interface, the mode options include the first option, and the first option corresponds to the mode of using two cameras to capture images. The electronic device displays a fourth interface in response to the user's selection operation on the first option. The fourth interface is a viewing interface where the electronic device is recording. The fourth interface includes the third preview image collected by the second camera with the first collection parameters and the fourth preview image collected by the third camera with the first collection parameters.

That is to say, with the method of this embodiment, in the case of allowing switching to the mode of capturing images using two cameras, if the switching is completed, the acquisition parameters before the switching can be continued to be used. In this way, the consistency of the video parameters before and after switching can also be ensured, thereby improving the viewing experience of the user. For example, the preset parameter threshold is 1080p, if the acquisition parameter before the switching is 720p, then the switching may be allowed, and the resolution before and after the switching is both 720p. That is, the resolution does not change, and the clarity of the video is consistent.

In another possible design manner of the third aspect, the third interface does not include the first control in the operable state specifically: the third interface includes the first control in the inoperable state. For example, the first control in an inoperable state is a grayed out mode icon. After the electronic device displays the third interface, the electronic device receives a user's second operation on the first control that is in an inoperable state, and the second operation is used to trigger the electronic device to switch the recording mode. In response to the user's second operation on the first control in the inoperable state, the electronic device displays first prompt information on the third interface, where the first prompt information is used to prompt that the two cameras cannot be switched to collect images.

That is to say, by using the method of this embodiment, the electronic device can clearly prompt the user that it is currently impossible to switch to using two cameras to capture images after the user misoperates the first control in the inoperable state. Thereby improving the efficiency of human-computer interaction.

In another possible design manner of the third aspect, the third interface does not include the first control in an operable state specifically: the third interface does not include the first control. For example, the third interface does not include a panel display control.

The video shooting method in the following embodiments can be implemented in the mobile phone 100 having the above hardware structure.

The video shooting method provided in the embodiment of the present application can be applied to various scenes requiring video shooting in the mobile phone 100, for example, wedding scene, friend gathering, travel and other scenes. Moreover, in recent years, with the development of video platforms, various new forms of video have emerged, one of which is a typical form of video log (video log, vlog), and vlog uses images instead of text or photos to carry logs form of content. In the process of shooting a vlog, it is usually necessary to shoot multiple objects, for example, to shoot the user himself and the environment where the user is located. Or, the same subject needs to be photographed with different visions, for example, a close-up and a distant view of the same stage scene.

However, limited by the limitation of the video shooting function in the conventional technology, it is usually difficult to meet the above-mentioned requirements in the new video format.

Based on this, an embodiment of the present application provides a video shooting method, which is implemented based on a new video shooting function. Wherein, the video shooting function may also be called a multi-lens video recording mode, which constitutes multiple shooting modes of the camera function together with various common shooting modes such as aperture, night scene, portrait, photo taking, and video recording. Moreover, in the multi-camera recording mode, the mobile phone 100 can simultaneously turn on at least two cameras to capture preview images and simultaneously display the preview images captured by the at least two cameras in the viewfinder interface.

Exemplarily, the viewfinder interface 201a of the camera application shown in (a) in FIG. 2A includes a submenu 202a, and the submenu 202a not only includes various common shooting modes such as aperture, night scene, portrait, photo taking, and video recording, but A multi-camera recording mode is also included. Then, the user selects the multi-camera video recording mode, which can trigger the mobile phone 100 to start the multi-camera video recording. For example, the mobile phone may display the viewfinder interface 203 shown in (b) of FIG. 2A in response to the user's selection operation of the multi-camera recording mode. The viewing interface 203a includes a preview image 204a captured by camera a and a preview image 205a captured by camera b. That is, there are two cameras capturing preview images at the same time.

It should be noted that the viewfinder interface 203a shown in (b) of FIG. 2A only includes preview images captured by the two cameras. However, during actual implementation, the viewfinder interface of the multi-mirror video recording mode may also include preview images collected by three cameras, four cameras... the embodiment of the present application does not use the number of cameras shown in (b) in FIG. 2A limit. In the following embodiments, two cameras will be used as an example to illustrate the solution of the present application.

It should be understood that, in the scenario where camera a and camera b, that is, two cameras are used to capture preview images at the same time, camera a and camera b may be a combination of any two cameras among the multiple cameras of the mobile phone 100 . For example, in the viewing interface 203a shown in (b) of FIG. 2A , camera a may be a rear main camera, and camera b may be a front camera. As another example, the viewfinder interface 201b shown in (a) of FIG. 2B includes a preview image 202b captured by the rear telephoto camera and a preview image 203b captured by the rear wide-angle camera. That is, camera a may be a rear telephoto camera, and camera b may be a rear wide-angle camera.

It should be noted that the preview image 204a and the preview image 205a in the viewfinder interface 203a shown in (b) of FIG. 2A are displayed in a split-screen layout. In actual implementation, in the viewfinder interface of the multi-camera recording mode, the preview images collected by the two cameras can also be displayed in a picture-in-picture layout. Exemplarily, the mobile phone may also display a viewfinder interface 204b shown in (b) of FIG. 2B , where the viewfinder interface 204b includes a preview image 205b collected by camera a and a preview image 206b collected by camera b. Wherein, the preview image 205b is displayed in the large window (ie full-screen window) 205B, the preview image 206b is displayed in the small window 206B, and the small window 206B is inside the large window 205B. That is, the preview image 205b and the preview image 206b are displayed in a picture-in-picture layout.

In addition, in some embodiments, in the multi-camera recording mode, the mobile phone 100 can switch from two cameras to a single camera to take a view in response to the user's operation (for the specific implementation, please refer to the description of Embodiment 1 below). That is to say, in the multi-camera recording mode, the function of collecting preview images by a single camera can also be provided.

Exemplarily, in the multi-camera video recording mode, the mobile phone 100 may display the viewfinder interface 201c shown in (a) of FIG. 2C . The viewfinder interface 201c includes a preview image 202c captured by a single camera (such as a front camera). Alternatively, the mobile phone may display the viewfinder interface 203c shown in (b) of FIG. 2C. The viewfinder interface 203c includes a preview image 204c captured by a single camera (such as a rear main camera).

Mode icon: the mode icon is used to indicate the multi-mirror mode currently adopted by the mobile phone 100 , that is, the camera currently capturing the preview image, and the layout of the preview image. For example, the mode icon is the icon 215 in the viewfinder interface 203a shown in (b) of FIG. 2A. The icon 215 is composed of a blank rectangle and a rectangle with a smiling face, the blank rectangle represents a rear camera, and the rectangle with a smile represents a front camera. And, a blank rectangle and a rectangle with a smiley face are arranged one above the other, indicating that the preview image is displayed in a top-bottom layout.

It should be noted that, in each multi-mirror mode, the mobile phone 100 can capture preview images with a specific camera, and display the preview images in a specific layout. Wherein, the specific camera may be any camera in the mobile phone 100 , or a combination of any two cameras in the mobile phone 100 . Specific layouts include split-screen layouts, picture-in-picture layouts, and/or full-screen layouts.

In the following embodiments, for convenience of description, the multi-mirror mode mainly includes: a mode in which a front camera and a rear camera are used to capture preview images and display them in a split-screen layout (referred to as the front and rear dual-mirror mode, as shown in Figure 2A The multi-mirror mode corresponding to the viewfinder interface 203a shown in (b)); the mode in which two rear cameras are used to collect preview images and display them in a split-screen layout (referred to as the rear-rear dual-mirror mode, as shown in Figure 2B (a) the multi-mirror mode corresponding to the viewfinder interface 201b shown); adopt a front camera and a rear camera to collect preview images, and display the mode with the picture-in-picture layout (abbreviated as picture-in-picture mode, as shown in Figure 2B The multi-mirror mode corresponding to the viewfinder interface 204b shown in (b) in (b); It is a single front mode, such as the multi-mirror mode corresponding to the viewfinder interface 201c shown in (a) in Figure 2C; if a rear camera is used, it is simply called a single rear mode, as shown in (b) in Figure 2C The multi-mirror mode corresponding to the viewfinder interface 203c).

Usually, the mobile phone 100 enters the viewfinder interface of the front and rear dual-mirror mode by default in response to the user's selection operation of the multi-mirror video recording mode. That is to say, in the multi-mirror recording mode, the default multi-mirror mode is the front and rear dual-mirror mode. Other multi-mirror modes are directly or indirectly obtained by switching from the front and rear dual-mirror modes.

Flash light icon: the flash light icon is used to trigger the mobile phone 100 to set the flash light parameters when shooting. For example, the flashlight icon is the icon 216 in the viewfinder interface 203a shown in (b) of FIG. 2A .

Filter icon: the filter icon is used to trigger the mobile phone 100 to add a filter when shooting. For example, the filter icon is the icon 217 in the viewfinder interface 203a shown in (b) of FIG. 2A. For the specific content of adding filters, please refer to the description of Embodiment 3 below, and no detailed description will be given here.

Setting icon: the setting icon 218 is used to trigger the mobile phone 100 to set camera parameters. For example, the setting icon is the icon 218 in the viewfinder interface 203a shown in (b) of FIG. 2A.

Zoom control: the zoom control is used to trigger the mobile phone 100 to adjust the zoom ratio, so as to switch between multiple rear cameras. For example, the zoom control is the zoom bar 219 in the viewfinder interface 203a shown in (b) in FIG. . For the specific content of switching the rear camera through the zoom bar, please refer to the description of Embodiment 1 below, and will not be described in detail here.

Regarding the multi-camera recording mode, the previous article mainly uses the viewfinder interface before recording to illustrate. It should be understood that in the multi-camera recording mode, the number of cameras turned on during recording, the layout of preview images, etc. are basically similar to those before recording.

Exemplarily, in a scene where two cameras are used for framing. Before recording, the mobile phone 100 may display the viewfinder interface 203a before recording shown in (b) in FIG. 2A, and during recording, the mobile phone 100 may display the viewfinder interface 201d shown in (a) in FIG. 2D. The viewfinder interface 201d includes a preview image 202d collected by camera a (such as a rear main camera) and a preview image 203d collected by camera b (such as a front camera). Wherein, the preview image 202d and the preview image 203d are displayed in a split-screen layout.

Or, before recording, the mobile phone 100 may display the viewfinder interface 201b shown in (a) in FIG. 2B , and during recording, the mobile phone 100 may display the viewfinder interface 204d shown in (b) in FIG. 2D . The viewing interface 204d includes a preview image 205d collected by camera a (such as a rear telephoto camera) and a preview image 206d collected by camera b (such as a rear wide-angle camera). Wherein, the preview image 205d and the preview image 206d are displayed in a split-screen layout.

Or, before recording, the mobile phone 100 may display the viewfinder interface 204b before recording shown in (b) in FIG. 2B , and during recording, the mobile phone 100 may display the viewfinder interface 207d shown in (c) in FIG. 2D . The viewing interface 207d includes a preview image 208d collected by camera a (such as a rear main camera) and a preview image 209d collected by camera b (such as a front camera). A preview image 208d is displayed in a large window (ie, a full screen window) 208D, and a preview image 209d is displayed in a small window 209D. Wherein, the large window 208D includes a small window 209D. That is, the preview image 208d and the preview image 209d are displayed in a picture-in-picture layout.

Also exemplary, in a scene where a single camera is used to view the scene. Before recording, the mobile phone 100 may display a viewfinder interface 201c shown in (a) in FIG. 2C , and during recording, the mobile phone 100 may display a viewfinder interface 201e shown in (a) in FIG. 2E . The viewing interface 201e includes a preview image 202e captured by a single camera (such as a front camera).

Or, before recording, the mobile phone 100 may display the viewfinder interface 203c shown in (b) in FIG. 2C, and during recording, the mobile phone 100 may display the viewfinder interface 203e shown in (b) in FIG. 2E. The viewfinder interface 203e includes a preview image 204e captured by a single camera (such as a rear main camera).

It should be noted that in the multi-camera recording mode, the elements in the viewfinder interface during recording and the elements in the viewfinder interface before recording will be different. Usually, one or more of the following elements can also be included in the viewfinder interface in recording:

Camera control: the camera control is used to trigger the mobile phone 100 to capture video frames during video shooting. For example, the camera control is the control 220 in the viewfinder interface 201d shown in (a) of FIG. 2D .

End recording control: the end recording control is used to trigger the mobile phone 100 to end video recording. For example, the control to end recording is the control 221 in the viewfinder interface 201d shown in (a) of FIG. 2D .

Pause recording control: The pause recording control is used to trigger the mobile phone 100 to pause video recording. For example, the pause recording control is the control 222 in the viewfinder interface 201d shown in (a) of FIG. 2D .

Front and rear camera switching controls: Similar to the viewfinder interface before recording, the viewfinder interface during recording also includes front and rear camera controls. For example, the control for switching the front and rear cameras is the control 223 in the viewfinder interface 201d shown in (a) of FIG. 2D . Similarly, for the specific content of switching between the front and rear cameras, please refer to the description of Embodiment 1 below, which will not be described in detail here.

Panel display control: the panel display control is used to trigger the mobile phone 100 to display the selection panel of the multi-mirror mode. For example, the panel display control is the control 224 in the viewfinder interface 201d shown in (a) of FIG. 2D . Wherein, the mode panel selection control may be static, or the panel display control may also be dynamic. If the panel display control is dynamically displayed, the user's attention can be attracted to the panel display control. Thereby guiding the user to use the control. For the selection panel and the specific content of switching the multi-mirror mode through the selection panel, please refer to the description of Embodiment 1 below, and no detailed description will be given here.

Mode icon: Similar to before recording, the mode icon is also included in the viewfinder interface during recording. For example, the mode icon is the control 225 in the viewfinder interface 201d shown in (a) of FIG. 2D.

Double-speed logo: the double-speed logo is used to indicate the double speed at which the mobile phone 100 plays the current preview frame. For example, the double-speed logo is the logo 226 in the viewfinder interface 201d shown in (a) of FIG. 2D , and the logo 226 indicates that the mobile phone 100 will play the current preview frame at 1X speed. It should be noted that during the recording process, the recording can be paused. In the paused state, the double speed indicator is in an inoperable state, such as grayed out. That is, the multiplier speed of the video playback cannot be adjusted in the paused state. For the specific content of switching the double speed value and playing at double speed, please refer to the description of the fifth embodiment below, and no detailed description will be given here.

Flash light icon: Similar to before recording, the viewfinder interface during recording also includes a flash light icon. It should be noted that flash parameters are usually not allowed to be adjusted during video recording, therefore, the flash icon during recording is inoperable. For example, the flashlight icon is the icon 227 in the viewfinder interface 201d shown in (a) of FIG. 2D , and the icon 227 is grayed out, indicating that it is inoperable.

Zoom controls: Similar to pre-recording, the viewfinder interface during recording also includes zoom controls. For example, the zoom control is the zoom bar 228 in the viewfinder interface 201d shown in (a) of FIG. . For the specific content of switching the rear camera through the zoom bar, please refer to the description of Embodiment 1 below, and will not be described in detail here.

In the above, the multi-camera recording mode is mainly explained in the form of vertical screen. It should be understood that the horizontal screen mode is also basically similar to the vertical screen mode. The subtle differences between the horizontal screen format and the vertical screen format will be described later in the relevant content of the embodiments below, and will not be described in detail here.

In the following embodiments, the description of the multi-mirror video recording mode will be combined with the foregoing, and the front and rear dual-mirror modes, the rear and rear dual-mirror modes, the picture-in-picture mode, and the single front (or rear) mode in the multi-mirror video mode will be mainly used. As an example, let’s further illustrate the mode switching function (such as Embodiment 1), beauty function (such as Embodiment 2), filter function (such as Embodiment 3), high-resolution recording and/or High frame rate recording (such as Embodiment 4), double speed function (Embodiment 5) and micro movie function (Embodiment 6).

Embodiment 1, mode switching function.

A video shooting method provided in the embodiment of the present application can be applied to the mobile phone 100 . Among them, in the viewfinder interface of the multi-camera recording mode (including the viewfinder interface before recording and the viewfinder interface during recording), the mobile phone 100 may display multiple mode options for the user to select in response to the user's operation 1 . Wherein, each mode option corresponds to a multi-mirror mode. Then, the mobile phone 100 may switch to the corresponding multi-mirror mode in response to the user's selection operation on any mode option. In this way, it is possible to flexibly switch the multi-mirror mode before recording or during recording.

The solution of this application will be described below by switching before recording and during recording respectively.

First, switch to multi-mirror mode before recording. Before recording, operation 1 mainly refers to the user's click operation on the mode icon.

The embodiment of the present application provides a video shooting method, which can switch the multi-mirror mode before starting to record in the multi-mirror video recording mode. As shown in Figure 3A, the video shooting method includes:

S301a, the mobile phone 100 displays interface a, where the interface a is a viewfinder interface before recording in sub-mode 1. The interface a includes the mode icon 1 of the sub-mode 1 . Wherein, sub-mode 1 includes front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode or single rear mode.

S302a. The mobile phone 100 displays multiple mode options in interface a in response to the user's click operation on the mode icon 1 . Wherein, multiple mode options correspond to multiple multi-mirror modes one by one.

Exemplarily, sub-mode 1 is the front and rear dual-mirror mode, then interface a may be the viewfinder interface 203a shown in (b) in FIG. 2A , and mode icon 1 may be the icon 215 in the viewfinder interface 203a. In response to the user's click operation on the icon 215, the mobile phone 100 may further display a selection panel 310 on the viewfinder interface 203a shown in (a) of FIG. 3B. The selection panel 310 includes mode options of five modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode.

In some embodiments, each mode option may include an identifier of a multi-mirror mode, which is used to indicate a different multi-mirror mode. For example, the abbreviation "Front/Rear" in the selection panel 310 of (a) in FIG. 3B indicates a front-rear dual-mirror mode. As another example, the abbreviation "picture in picture" in the selection panel 310 of (a) in FIG. 3B indicates the picture in picture mode.

In some other embodiments, each mode selection may include a layout style of the multi-mirror mode, which is used to indicate the layout of the preview image captured by the camera in the multi-mirror mode in the viewfinder interface. Wherein, the mobile phone 100 may represent the layout style by means of pictures, picture sizes and arrangement of pictures. Wherein, the picture may be collected by the camera in real time, or may be preset. By adopting this embodiment, before switching the multi-mirror mode, the layout styles of various multi-mirror modes can be provided to the user, and the switching can be convenient, fast and accurate. Thus, the switching efficiency and accuracy are improved.

For example, in the selection panel 310 of (a) in FIG. 3B, the preview image collected by the rear camera is represented by a plant picture, and the preview image collected by the front camera is represented by a portrait picture, and the vertical arrangement of the plant picture and the face picture can indicate the front and back. The layout effect of the dual mirror mode.

As another example, in the selection panel 310 of (a) in Fig. 3B, the preview image collected by the rear camera is represented by the plant picture, and the preview image collected by the front camera is represented by the portrait picture, then the plant picture can be indicated in the face picture. The layout effect of the picture-in-picture dual-mirror mode.

In some embodiments, among the plurality of mode options, the mode option of the currently employed multi-mirror mode (eg, sub-mode 1) may be highlighted. This facilitates indicating the currently employed multi-mirror mode.

Still taking the sub-mode 1 as the front and rear dual-mirror mode as an example, in the selection panel 310 of (a) in FIG. 3B . The layout style frame of the mode options of the front and rear dual-mirror mode is displayed in bold. So as to achieve outstanding effect.

In some embodiments, the mobile phone 100 displays a mode icon (eg, mode icon 1 ) in state 1 when multiple mode options are not displayed. In this case, the mobile phone 100 may display a plurality of mode options in response to the user's click operation on the mode icon. When displaying multiple mode options, the mobile phone 100 displays a mode icon (eg, mode icon 1 ) in state 2 . In this case, the mobile phone 100 may close the display of multiple mode options in response to the user's click operation on the mode icon. For example, state 1 is a normal display state, and state 2 is a grayed state. Therefore, the display state of the mode option can be indicated by the display state of the mode icon, so as to realize the unification of the interface elements.

In some embodiments, when multiple mode options are displayed, the mobile phone 100 closes the front and rear camera switching controls. For example, the front and rear camera switching controls are no longer displayed at the lower right corner of the viewfinder interface 203a shown in (a) of FIG. 3B . In the case of displaying multiple mode options, the user's demand is usually to switch the multi-mirror mode through the mode option, rather than switching the camera through the front and rear camera switching controls. At this time, turning off the display of the front and rear camera switching controls will not affect the user's needs on the one hand, and on the other hand, it can simplify the interface elements and facilitate the operation of switching the multi-mirror mode.

In the above description about S302a, it is mainly explained that the sub-mode 1 is the front and rear dual-mirror mode. It should be understood that the principle when the sub-mode 1 is a rear-rear dual-mirror mode, a picture-in-picture mode, a single front mode or a single rear mode is also similar. The following simply shows a schematic diagram of displaying multiple mode options when the sub-mode 1 is respectively the rear-rear dual-mirror mode, the picture-in-picture mode and the single rear mode.

Example 1, if the sub-mode 1 is the rear-rear dual-mirror mode, the interface a may be the viewfinder interface 201b shown in (a) of FIG. 2B , and the mode icon 1 may be the icon 230 in the viewfinder interface 201b. In response to the user's click operation on the icon 230, the mobile phone 100 may further display a selection panel 311 in the viewfinder interface 201b shown in (b) of FIG. 3B. The selection panel 311 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of the rear dual-mirror mode is highlighted.

Example 2, if the sub-mode 1 is the picture-in-picture mode, the interface a may be the viewfinder interface 204b shown in (b) of FIG. 2B , and the mode icon 1 may be the icon 231 in the viewfinder interface 204b. In response to the user's click operation on the icon 231, the mobile phone 100 may further display a selection panel 312 on the viewfinder interface 204b shown in (c) of FIG. 3B. The selection panel 312 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of the picture-in-picture mode is highlighted.

Example 3, sub-mode 1 is a single rear mode (single front mode is the same), then interface a can be the viewfinder interface 203c shown in (b) in Figure 2C, and mode icon 1 can be an icon in the viewfinder interface 203c 232. In response to the user's click operation on the icon 232, the mobile phone 100 may further display a selection panel 313 on the viewfinder interface 203c shown in (d) of FIG. 3B. The selection panel 313 includes 5 mode options including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of single rear mode is highlighted.

It should be noted that, in some embodiments, when sub-mode 1 is a single front mode or a single rear mode, when the mobile phone 100 displays multiple mode options, only the front and rear dual-mirror mode, the rear and rear dual-mirror mode and Mode options for picture-in-picture mode while retaining front and rear camera switching controls. In this way, on the premise of reducing the changes to the viewfinder interface, through multiple mode options, you can switch to front and rear dual mirror mode, rear and rear dual mirror mode or picture-in-picture mode; through the front and rear camera switching controls, you can switch between single front mode and Switch between single rear mode.

In practice, the display of multiple mode options may block the preview image in the viewfinder interface, thereby affecting the preview.

Based on this, in some embodiments, when multiple mode options are displayed on the viewfinder interface, the mobile phone 100 can hide the multiple mode options in response to the user's operation (such as operation 2), thereby flexibly turning off the multiple mode options. display to avoid blocking the preview image.

Wherein, operation 2 may be a preset gesture 1 input by the user on the viewfinder interface. For example, operation 2 may be a sliding gesture input by the user in the viewfinder interface 201b shown in (b) of FIG. 3B . Alternatively, operation 2 may be a click operation or a long press operation by the user on an area other than multiple mode options and where elements such as icons and controls are not displayed. Alternatively, the viewfinder interface includes a panel hiding control, and operation 2 may be a user's click operation on the panel hiding control. Wherein, the panel hidden control may be a mode icon. For example, the panel hiding control may be the grayed-out icon 314 in the viewing interface 201b shown in (b) of FIG. 3B . Alternatively, the panel hide control can be a preset control in the selection panel. For example, the panel hiding control may be the control 3111 in the viewfinder interface 201b shown in (b) of FIG. 3B .

In some other embodiments, when the current viewfinder interface displays multiple mode options, the mobile phone 100 starts from displaying the multiple mode options, and if no user operation on the multiple mode options is received within the preset time period, then Hides the multiple mode options. In this way, when the user does not operate for a long time, multiple mode options can be hidden to avoid affecting the preview.

S303a. The mobile phone 100 responds to the user's selection operation on mode option 1, and displays interface b. Mode option 1 corresponds to sub-mode 2, interface b is the viewfinder interface before recording in sub-mode 2. The interface b includes a mode icon 2 of sub-mode 2, which is different from sub-mode 1.

Exemplarily, taking the sub-mode 1 as an example of the front and rear dual-lens mode, the mobile phone 100 may display the viewfinder interface 203a shown in (a) of FIG. 3B , and the viewfinder interface 203a includes a selection panel 310 .

If the mode option 1 is the option 3101 in the selection panel 310, that is, the sub-mode 2 is the rear-rear dual-mirror mode. In response to the user's selection operation of the option 3101, the mobile phone 100 may display the viewfinder interface 201b shown in (a) of FIG. 2B.

If the mode option 1 is the option 3102 in the selection panel 310, that is, the sub-mode 2 is the picture-in-picture mode. In response to the user's selection operation of the option 3102, the mobile phone 100 may display the viewfinder interface 204b shown in (b) of FIG. 2B.

If the mode option 1 is the option 3103 in the selection panel 310, that is, the sub-mode 2 is a single rear mode. In response to the user's selection operation of the option 3103, the mobile phone 100 may display the viewfinder interface 203c shown in (b) of FIG. 2C.

If the mode option 1 is the option 3104 in the selection panel 310, that is, the sub-mode 2 is a single front mode. In response to the user's selection operation of the option 3104, the mobile phone 100 may display the viewfinder interface 201c shown in (a) of FIG. 2C.

In the above description about S303a, it is mainly explained that the sub-mode 1 is the front and rear dual-mirror mode. It should be understood that the principle when the sub-mode 1 is a rear-rear dual-mirror mode, a picture-in-picture mode, a single front mode or a single rear mode is also similar. That is, in response to the user's selection operation on any mode option, the mobile phone 100 may display the viewfinder interface of the sub-mode corresponding to the mode option. No more details here.

It should be noted that the aforementioned S301a-S303a only illustrates a switching process before video recording. In actual implementation, two or more multi-mirror modes can be switched between, and each switching process can refer to the description of S301a-S303a. In each switching process, the multi-mirror mode before switching is recorded as sub-mode 1, and the multi-mirror mode after switching is recorded as sub-mode 2.

In summary, using the method of this embodiment, after entering the viewfinder interface of the multi-mirror video recording mode and before starting to record, the mobile phone 100 can flexibly switch between multiple multi-mirror modes according to the user's selection of the multi-mirror mode . This makes it possible to switch to a satisfactory multi-mirror mode before starting video recording.

Second, switch the multi-mirror mode during recording. During the recording, operation 1 may be the user's click operation on the mode icon, or the user's click operation or swipe up operation on the panel display control.

The embodiment of the present application provides a video shooting method, which can switch the multi-mirror mode during recording in the multi-mirror video mode. In this embodiment, it is mainly described by taking operation 1 as an example where the user slides up the panel display control. As shown in Figure 3C, the video shooting method includes:

S301c, the mobile phone 100 displays an interface c, where the interface c is a viewfinder interface being recorded in sub-mode 1. The interface c includes panel display controls. Wherein, sub-mode 1 includes front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode or single rear mode. The panel display control is used to trigger the mobile phone 100 to display a selection panel, the selection panel includes multiple mode options, and the multiple mode options correspond to multiple multi-mirror modes one by one.

In some embodiments, the panel presentation controls are only present in the recording. In this way, a new shortcut for switching between multi-mirror modes is provided during recording, which is convenient for switching between multi-mirror modes during recording. For example, sub-mode 1 is the front and rear dual-mirror mode, then interface c can be the viewfinder interface 201d shown in (a) in FIG. That is, control 224 is a panel presentation control.

S302c, the mobile phone 100 responds to the user's upward sliding operation on the panel display control, and displays multiple mode options on the interface c.

Exemplarily, if the sub-mode 1 is the front and rear dual-mirror mode, the interface c may be the viewfinder interface 201d shown in (a) of FIG. 2D , and the panel display control may be the control 224 in the viewfinder interface 201d. The mobile phone 100 may further display a selection panel 320 in the viewfinder interface 201d shown in (a) of FIG. 4 in response to the user's upward sliding operation on the control 224 . The selection panel 320 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode.

Wherein, regarding the selection panel, mode options and display thereof, reference may be made to relevant descriptions in the embodiment shown in FIG. 3A , which will not be repeated here. In this embodiment, the description is mainly focused on the differences between recording and pre-recording.

In some embodiments, when multiple mode options are displayed, the mobile phone 100 hides the panel display controls. For example, the panel presentation control is no longer displayed in the viewfinder interface 201d shown in (a) of FIG. 4 . In this way, interface elements can be simplified.

In some embodiments, similar to before recording, when multiple mode options are displayed, the mobile phone 100 closes the front and rear camera switching controls. For example, the front and rear camera switching controls are no longer displayed at the lower right corner of the viewfinder interface 201d shown in (a) of FIG. 4 .

In the above description about S302c, it is mainly explained that the sub-mode 1 is the front and rear dual-mirror mode. It should be understood that the principle when the sub-mode 1 is a rear-rear dual-mirror mode, a picture-in-picture mode, a single front mode or a single rear mode is also similar. The following simply shows a schematic diagram of displaying multiple mode options when the sub-mode 1 is respectively the rear-rear dual-mirror mode, the picture-in-picture mode and the single rear mode.

Example 1, if the sub-mode 1 is the rear-rear dual-mirror mode, the interface c may be the viewfinder interface 204d shown in (b) of FIG. 2D , and the panel display control may be the control 240 in the viewfinder interface 204d. The mobile phone 100 may further display a selection panel 321 in the viewfinder interface 204d shown in (b) of FIG. 4 in response to the user's upward sliding operation on the control 240 . The selection panel 321 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of the rear dual-mirror mode is highlighted.

Example 2, if the sub-mode 1 is the picture-in-picture mode, the interface c may be the viewfinder interface 207b shown in (c) of FIG. 2D , and the panel display control may be the control 241 in the viewfinder interface 207d. The mobile phone 100 may further display a selection panel 322 in the viewfinder interface 207d shown in (c) of FIG. 4 in response to the user's upward sliding operation on the control 241 . The selection panel 322 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of the picture-in-picture mode is highlighted.

Example 3, sub-mode 1 is a single front mode (the same is true for single rear mode), then interface a can be the viewfinder interface 201e shown in (a) in Figure 2E, and the panel display controls can be the controls in the viewfinder interface 201e 242. The mobile phone 100 may further display a selection panel 323 in the viewfinder interface 201e shown in (d) of FIG. 4 in response to the user's upward sliding operation on the control 242 . The selection panel 323 includes mode options of 5 modes including front and rear dual-mirror mode, rear-rear dual-mirror mode, picture-in-picture mode, single front mode and single rear mode. Among them, the mode option of single front mode is highlighted.

It should be noted that in some embodiments, similar to before recording, in the case that sub-mode 1 is a single front mode or a single rear mode, when the mobile phone 100 displays multiple mode options, only the front and rear dual-mirror modes, Mode options for rear dual-mirror mode and picture-in-picture mode, while retaining front and rear camera switching controls.

Multiple mode options also obscured the preview image in the viewfinder when displayed in a recording, affecting the preview. Therefore, the mobile phone 100 can also hide multiple mode options in a manner similar to that before video recording, which will not be repeated here.

S303c, the mobile phone 100 displays an interface d in response to the user's selection operation on mode option 1. Mode option 1 corresponds to sub-mode 2, and interface d is the viewfinder interface during sub-mode 2 recording. Submode 2 is different from submode 1.

The implementation principle and process of this S303c are similar to those of the previous S303a, for details, please refer to the description of the previous S303a. I won't repeat them here. The only thing to note is that the interface d is the viewfinder interface during recording, while the interface b in S303a is the viewfinder interface before recording.

It should be noted that the aforementioned S301c-S303c only illustrate a switching process before recording. In actual implementation, multiple multi-mirror modes can be switched in twos and multiple times. For each switching process, please refer to the description of S301c-S303c. In each switching process, the multi-mirror mode before switching is recorded as sub-mode 1, and the multi-mirror mode after switching is recorded as sub-mode 2.

In summary, using the method of this embodiment, after entering the viewfinder interface of the multi-mirror video recording mode and starting recording, the mobile phone 100 can flexibly switch between multiple multi-mirror modes according to the user's selection of the multi-mirror mode .

In the above-mentioned embodiment shown in FIG. 3C , the switching process during recording is mainly described by using operation 1 as the user's click operation on the panel display control. In some other embodiments, operation 1 is that the user clicks on the mode icon, and the implementation principle is the same, but the conditions for triggering the display of multiple mode options are different, which will not be repeated here. In addition, in recording, the above two forms of operation 1 can be combined. Therefore, multiple modes can be triggered to display multiple mode options, thereby improving the flexibility of switching.

It should be noted that the switching process before recording will not be reflected in the final video file. For example, if you switch from the front-rear dual-mirror mode to the rear-rear dual-mirror mode before recording, and then start recording, the final video file will not include the process of switching from the front-rear dual-mirror mode to the rear-rear dual-mirror mode before recording. Only videos recorded in the rear and rear dual-mirror modes will be presented.

Different from the above-mentioned switching before recording, the switching process during recording will be reflected in the final video file. Exemplarily, after S303c, the mobile phone generates the video file 1 in response to the user's operation 3 on the interface d. This operation 3 is used to trigger the mobile phone to end the video recording. For example, operation 3 may be the user's click operation on the end recording control. This video file 1 includes video stream a and video stream b. Wherein, video stream a is a video stream formed by recording video in sub-mode 1, and video stream b is a video stream formed by recording video in sub-mode 2.

Further, video stream a may be composed of n sub-video streams, n is a positive integer, and the value of n is equal to the number of cameras used in sub-mode 1. The n sub-video streams correspond to the n cameras used in sub-mode 1. That is, each sub-video stream in the n sub-video streams is composed of multiple frames of preview images collected by the corresponding camera adopted in sub-mode 1. Similarly, video stream b may be composed of m sub-video streams, m is a positive integer, and the value of m is equal to the number of cameras used in sub-mode 2. The m sub-video streams correspond to the m cameras used in sub-mode 2. That is, each sub-video stream in the m sub-video streams is composed of multiple frames of preview images collected by the corresponding camera adopted in sub-mode 2.

As an example, take sub-mode 1 as the front and rear dual-mirror mode, sub-mode 2 as the rear-rear dual-mirror mode, and switch to the multi-mirror mode once during video recording as an example. As shown in Figure 5, within the first 10 seconds from 00:00:00 (starting at the 0th second) to 00:09:59 (ending at the 9th second), the rear main camera and the front camera are used as front and rear dual mirrors mode to record video. At 00:09:59 (or 00:10:00), the mobile phone 100 switches the multi-mirror mode to the rear-rear dual-mirror mode, and adopts the rear telephoto camera and the rear wide-angle camera to collect preview images. Then, within 5 seconds from 00:10:00 (the start of the 10th second) to 00:14:59 (the end of the 14th second), the video will be recorded in the rear dual-mirror mode. At 00:14:59, the mobile phone 100 ends the video recording and generates a video file 1 . Video file 1 includes video stream a1, video stream a2, video stream b1, and video stream b2. Among them, the video stream a1 includes a multi-frame preview image collected by the rear main camera in the front-rear dual-mirror mode, and the video stream a2 includes a multi-frame preview image collected by the front camera in the front-rear dual-mirror mode. That is, video stream a includes two sub-video streams, namely, video stream a1 and video stream a2. The video stream b1 includes the multi-frame preview images collected by the rear telephoto camera in the rear dual-lens mode, and the video stream b2 includes the multi-frame preview images collected by the rear wide-angle camera in the rear dual-lens mode. That is, video stream b includes two sub video streams, namely, video stream b1 and video stream b2.

To sum up, by switching the multi-mirror mode during the recording process, a video file composed of video streams recorded in multiple multi-mirror modes can be recorded. This increases the flexibility and variety of video recording.

Further, in some scenes during the recording, the zoom control and the panel display control need to be displayed at the same time, and the panel display control may be adjacent to the zoom control. For example, in the viewfinder interface 207d during recording in the picture-in-picture mode shown in (c) of FIG. 2D , the panel display control 241 and the zoom control 243 are displayed adjacently. As another example, in the viewfinder interface 203e during recording in the single rear mode shown in (b) of FIG. 2E , the panel display control 244 and the zoom control 245 are displayed adjacently.

For the above scenario, in some embodiments, different controls are divided into non-interfering response mechanisms to accurately respond to user operations. In a specific implementation, in the viewfinder interface in single rear mode or picture-in-picture mode recording, the response hot zone of the panel display control (referred to as the panel display hot zone, including the panel display control) includes a zoom control The responsive hotspot (referred to simply as the zoom hotspot, which includes the zoom controls) of . Wherein, in the panel display hot area, the user inputs the line between the start point and the end point of the sliding operation, and the minimum angle between the bottom of the screen and the bottom of the screen is greater than the preset angle (such as 60°), the display selection of the mobile phone 100 can be triggered panel for switching between multi-mirror modes. In the zoom hot zone, the user inputs the line between the start point and the end point of the sliding operation, and the minimum angle between the bottom of the screen and the bottom of the screen is less than or equal to the preset angle (such as 60°), the mobile phone 100 can be triggered to switch the rear Camera. It should be understood that since the panel display hot zone includes the zoom hot zone, being in the zoom hot zone means being in the panel display area.

In this implementation manner, the panel display hotspot is relatively large, which can facilitate the user to trigger the mobile phone 100 to display the selection panel. Thereby, the difficulty of switching between multi-mirror modes can be reduced. At the same time, the mobile phone 100 responds to the user's operation based on the size of the smallest angle between the starting point and the end point of the user's input sliding operation and the bottom of the screen, which can accurately respond to the user's operation, and will not occur. confusion.

Exemplarily, take a single rear mode and a preset angle of 60° as an example. As shown in (a) in Figure 2F, in the viewfinder interface in single rear mode recording, the panel display hotspot includes the zoom hotspot, for example, the height of the panel display hotspot is 60 pixels (dp), and the width is the screen The width of the zoom hotspot is 130dp, and the width is also the width of the screen. Swipe operation 1: Swipe from the starting point A to the end point B along the arrow 1. Since point A and point B are both displayed in the hot zone on the panel, and the minimum angle between the line connecting point A and point B and the bottom of the screen is greater than 60°, Correspondingly, in response to the sliding operation 1 , the mobile phone 100 may display a selection panel for switching the multi-mirror mode. Swipe operation 2 from the starting point A, along the arrow 2, to the end point C, since point A and point C are both in the zoom hot zone, and the minimum angle between the line connecting point A and point C and the bottom of the screen is less than 60°, corresponding Yes, the mobile phone 100 can switch the rear camera for capturing images in response to the sliding operation 2 .

In addition, in other scenes before recording or during recording, such as in the viewfinder interface during recording in front-rear dual-mirror mode and rear-rear dual-mirror mode, or in the viewfinder interface before recording in various multi-mirror modes, the panel display The zoom controls are not displayed adjacent to the controls. In these scenarios, it is enough to divide the corresponding hot zones for the panel display controls separately. Wherein, for dynamic panel display controls and static panel display controls, different panel display hotspots may be set. For example, set a larger panel display hotspot for a dynamic panel display control.

Exemplarily, take the front and rear dual-mirror mode as an example. As shown in (b) in Figure 2F, in the viewfinder interface in the front and rear dual-mirror mode recording, the panel display control and the zoom control are far apart, and the panel display hotspot can be set as a rectangular area as shown in the figure, as shown The height is 60dp and the width is the width of the screen.

In the foregoing description of Embodiment 1, the multi-mirror mode is mainly switched through mode icons or panel display controls, but in actual implementation, it is not limited thereto. In some embodiments, the switching of the multi-mirror mode can also be triggered by a preset gesture. Exemplarily, in the vertical screen mode, in the case of using a single camera to capture images, the mobile phone 100 can respond to the user's sliding gesture from the lower edge or upper edge of the screen to the middle of the screen, and can start from the mode of using a single camera to capture images. to switch to the mode that uses two cameras to capture images. For example, switch to front and rear dual-mirror mode. Also exemplary, in the vertical screen mode, in the case of using two cameras to capture images, the mobile phone 100 responds to the user's sliding gesture from a position near the intersection area of the two preview images to the upper or lower edge of the screen , to switch from a mode that captures images with two cameras to a mode that captures images with a single camera. In this embodiment, the mobile phone 100 can be directly triggered to switch the multi-mirror mode through the preset gesture without displaying mode options, thereby improving the convenience of switching.

In the following embodiments, the scheme of the present application will be described mainly in the manner of switching the multi-mirror mode through the mode icon and panel display controls.

In the foregoing first embodiment, the multi-mirror mode is mainly switched through mode options, that is, switching of cameras, layout, and the like.

In some embodiments, in order to further improve the convenience of switching, the following switching methods are also provided:

Way 1, the mobile phone 100 is triggered to switch between the front camera and the rear camera through the front and rear camera switching controls.

Exemplarily, in the single front mode, the mobile phone 100 may switch to the single rear mode in response to the user's click operation on the front and rear camera switching control. Alternatively, in the single rear mode, the mobile phone 100 may switch to the single front mode in response to the user's click operation on the front and rear camera switching controls.

Also exemplary, in the front and rear dual-mirror mode or the picture-in-picture mode, the mobile phone 100 can switch the front camera to the rear camera (such as the rear main camera) in response to the user's click operation on the front and rear camera switching controls. .

As another example, in the rear and rear dual-mirror mode, the mobile phone 100 may switch one of the rear cameras to the front camera in response to the user's click operation on the front and rear camera switching controls, thereby switching to the front and rear dual-mirror mode. For example, the mobile phone 100 may display the viewfinder interface 201d shown in (a) in FIG.

Method 2, in the case that the currently adopted camera has a rear camera, the mobile phone 100 may be triggered to switch the rear camera through the zoom control.

Exemplarily, in the single rear-facing mode, the mobile phone 100 may switch to the corresponding rear-facing camera in response to the user's selection operation of the zoom speed in the zoom control. For example, when a 2x magnification is selected, the mobile phone 100 may switch to a rear 2x telephoto lens.

As another example, in the front and rear dual-mirror mode or the picture-in-picture mode, the mobile phone 100 may switch the current rear camera to another rear camera in response to the user's selection operation of the zoom speed in the zoom control. For example, in response to the user's sliding operation on the zoom bar 228 in the viewfinder interface 201d shown in (a) in FIG. Camera. If you slide from 1x to 2x, you can switch from the rear main camera to the rear 2x telephoto camera.

As another example, in the rear-rear dual-mirror mode, the mobile phone 100 may switch one of the rear cameras to the other rear camera in response to the user's selection operation of the zoom ratio in the zoom control. For example, in response to the user's sliding operation on the zoom bar in the viewfinder interface 204d shown in (b) in FIG. for other rear cameras. If you slide from 2x to 4x, you can switch from the rear 2x telephoto camera to the rear 4x telephoto camera.

The third way is to trigger the switch of the rear camera by zooming with your fingers. For example, opening the finger triggers switching to the rear telephoto camera. The larger the opening degree, the switch to the rear telephoto camera with a larger magnification. Pinch your fingers together to switch to the wide-angle camera.

It should be noted that if there are multiple front cameras, they can also be switched through method two or three.

Mode 4, by double-clicking the preview image in the dual-view viewfinder interface, the display areas of the preview images collected by the two cameras are swapped.

Exemplarily, in the front and rear dual-mirror mode, the mobile phone 100 may switch the display areas of the preview image captured by the front camera and the preview image captured by the rear camera in response to the user's double-click operation on any preview image. For example, the mobile phone 100 can switch the display areas of the preview image 202d and the preview image 203d in response to the user's double-click operation on the preview image 202d or the preview image 203d in the viewfinder interface 201d shown in (a) of FIG. 2D . After the adjustment, the preview image 202d is displayed below the preview image 203d.

As another example, in the rear-rear dual-mirror mode, the mobile phone 100 may switch the display areas of the preview images captured by the two rear cameras in response to the user's double-click operation on any preview image. For example, the mobile phone 100 can switch the display areas of the preview image 205d and the preview image 206d in response to the user's double-click operation on the preview image 205d or the preview image 206d in the viewfinder interface 204d shown in (b) of FIG. 2D . After the adjustment, the preview image 205d is displayed below the preview image 206d.

As another example, in the picture-in-picture mode, the mobile phone 100 may switch the display areas of the preview image captured by the front camera and the preview image captured by the rear camera in response to the user's double-click operation on any preview image. For example, the mobile phone 100 can switch the display areas of the preview image 208d and the preview image 209d in response to the user's double-click operation on the preview image 208d or the preview image 209d in the viewfinder interface 207d shown in (c) of FIG. 2D . After the adjustment, the preview image 208d is displayed in the small window 209D, and the preview image 209d is displayed in the large window 208D.

Mode 5, in the picture-in-picture mode, the mobile phone 100 can be triggered to zoom the window size of the small window by zooming the small window window with a finger or dragging the edge of the small window.

Embodiment 2, beauty function.

A video shooting method provided in the embodiment of the present application can be applied to the mobile phone 100 . Wherein, in the multi-mirror recording mode, in the viewfinder interface before recording, the mobile phone 100 may display one or more A beauty effect control for users to choose a beauty effect. Then, the mobile phone 100 may set the beauty effect in the multi-camera recording mode in response to the user's operation on the beauty effect control. In this way, the beauty setting can be completed before recording in the multi-camera recording mode.

Exemplarily, the beauty control is the control 213 in the viewfinder interface 203a shown in (b) of FIG. 2A. In response to the user's click operation on the control 213 in the viewfinder interface 203a shown in (b) in FIG. 2A , the mobile phone 100 may further display a beauty adjustment bar 601 in the viewfinder interface 203a shown in (a) in FIG. 6A , the beautification adjustment bar 601 is recorded as a beautification effect control. As shown in (a) in FIG. 6A , the default beauty level in the beauty adjustment bar 601 is level 5. Then, the mobile phone 100 may receive the user's sliding operation on the beautification adjustment bar 601 , that is, a selection operation on the beautification level. As shown in (b) of FIG. 6A , the mobile phone 100 may receive the user's selection operation on level 6 in the beauty adjustment bar 601 . The mobile phone 100 may adjust the beautification effect to a level 6 beautification effect in response to the user's selection operation of level 6.

It should be noted that in the above examples of (a) in FIG. 6A and (b) in FIG. 6A , the implementation of setting the beautification effect on the mobile phone 100 is described only by taking the beautification effect control bar as an example. In practice, the beauty effect control may also be in other forms. For example, the beautifying effect control may also be a plurality of effect options, and the plurality of effect options correspond to various beautifying effects one by one. In the embodiment herein, the solution of the application is mainly described by taking the beauty effect control as a beauty adjustment bar as an example.

In some embodiments, when the user operates the beauty adjustment bar to adjust the beauty level, the mobile phone 100 only displays the preview image and the beauty adjustment bar. And hide other elements in the viewfinder interface. In this way, it is convenient for the user to accurately adjust the beauty level. For example, as shown in (b) in FIG. 6A, during the user's operation of the beauty adjustment bar, the mobile phone 100 hides interface elements such as the mode icon, the flash icon, the start recording control, and the front and rear camera switching controls, and only displays the preview image. and beauty adjustment bar.

It should be noted that in the multi-mirror recording mode, in the multi-mirror mode that uses two or more cameras to collect images, such as the front and rear dual-mirror mode, the rear-rear dual-mirror mode or the picture-in-picture mode, usually only when the subject is a portrait , there is a need for beauty. At the same time, when two or more cameras are used to collect images, the front camera is usually used to collect portraits. Based on this, in some embodiments, in the multi-mirror mode in which two or more cameras are used to collect images, only the images collected by the front camera support beautification. Further, in this embodiment, the mobile phone 100 may display the beautification control near the image of the front camera in the viewfinder interface. In this way, it is convenient to clarify the target of beauty.

For example, the viewing interface 203a shown in (b) of FIG. 2A includes a control 213, and the control 214 is used to trigger the mobile phone 100 to adjust the beauty level. That is, the control 213 is a beauty control. The control 213 is displayed in the display area of the image (such as a face image) collected by the front camera in the front and rear dual-mirror mode. As another example, the viewfinder interface 204b shown in (b) of FIG. 2B includes a beautification control, and the beautification control displays the display area ( Such as the bottom of the small window).

In this embodiment, in the front-rear dual-mirror mode and the picture-in-picture mode, the images (usually portraits) captured by the front camera support beauty, and after setting the beauty effect through the beauty control, only the front camera captures The beauty effect can be added to the image of . That is to say, in the front and rear dual-mirror mode and the picture-in-picture mode, the beautification control is only used to set the beautification effect of the image captured by the front camera.

Exemplarily, take the viewfinder interface shown in (b) in FIG. 2A before recording in the front and rear dual-mirror mode as an example. The viewfinder interface 602 shown in FIG. 6B can be displayed. In the viewfinder interface 602, only the preview image 604 captured by the front camera is added with 6-level beautification effects, while the preview image 603 captured by the rear camera is not added with beautification. Effect.

In addition, in the multi-mirror mode in which two or more cameras are used to collect images, if the currently used multi-mirror mode does not include a front-facing camera (such as a rear and rear dual-mirror mode), the mobile phone 100 may not display Beautification controls, or display the beautification controls at a position near the bottom of the mobile phone 100 by default. For example, the viewfinder interface 201b shown in (a) in FIG. 2B is the viewfinder interface of the rear and rear dual-mirror mode, and the cameras for collecting images in the rear and rear dual-mirror mode are two rear cameras, that is, the front camera and the mobile phone are not included. 100, the beautification control can be displayed near the bottom of the mobile phone 100.

Or, in single front mode or single rear mode, it is possible to use the current single camera to capture portraits, so there may be a need for beautification. Based on this, in some embodiments, both the front camera and the rear camera support beauty. Further, in either the single front mode or the single rear mode, the mobile phone 100 can display a beauty control on the viewfinder interface. Moreover, after setting the beautification effect through the beautification control, the beautification effect can be added to the preview image displayed in full screen.

That is to say, in the common multi-mirror mode, the single front mode and the single rear mode support beauty, and the images captured by the front camera in the front and rear dual view mode and the picture-in-picture mode support beauty (also called partial support). Beautification), the rear dual mirror mode usually does not support beautification. Based on the description of the foregoing first embodiment, it can be seen that in the multi-mirror video recording mode, the mobile phone 100 can switch between multiple multi-mirror modes. On this premise, it is possible to switch from a mode that supports beauty (such as a single rear mode) to a mode that partially supports beauty or does not support beauty; or, it may also switch from a mode that partially supports beauty to one that does not support beauty. color pattern.

Based on this, the embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can intelligently set the beautification effect according to the multi-mirror mode before and after switching, so as to adapt to the support of the multi-mirror mode for beautification. The following uses several typical scenarios to illustrate the specific implementation of the smart setting beauty effect:

Scenario 1, switching from the mode of capturing images with a single camera to capturing images with two cameras, and the switched two cameras include the rear camera.

Please refer to FIG. 6C , which is a flowchart of a video shooting method provided by the embodiment of the present application, which can be applied to the mobile phone 100 . In this embodiment, scene 1 is mainly taken as an example to illustrate the specific implementation of intelligently setting the beautifying effect.

As shown in Figure 6C, the video shooting method of this embodiment may include:

S611. The mobile phone 100 displays an interface a, where the interface a is a viewfinder interface for video recording by the first camera. The interface a includes a first preview image displayed in full screen. Wherein, the first preview image is obtained by the mobile phone 100 after adding a first beauty effect to the first image captured by the first camera. The first camera is a front camera or a rear camera.

Wherein, the viewfinder interface for video recording may be the viewfinder interface before recording, or the viewfinder interface for video recording. That is, interface a (also referred to as the first interface) may be a viewfinder interface before recording, or may be a viewfinder during recording. That is to say, the method of this embodiment can be used to intelligently set the beautifying effect before recording and during recording.

In some embodiments, the beautification effect in the interface a is set by the mobile phone 100 according to the user's operation on the beautification control and the beautification effect control.

In this embodiment, before S611, the mobile phone 100 needs to set the beautifying effect recorded by the first camera as the first beautifying effect according to the user's operation on the beautifying control and the beautifying effect control. The specific process of setting the beautification effect has been described above, and will not be repeated here. After finishing setting the beautifying effect, the mobile phone 100 may display an interface a, and the preview image in the interface a has the first beautifying effect. That is, the screen a is a viewfinder screen before recording. Or, after completing the beautification settings, the mobile phone 100 may display interface a in response to the user's operation of starting video recording (such as clicking the start recording control), and the preview image in interface a has the first beautification effect. That is, the screen a is a viewfinder screen currently being recorded. In the following embodiments, the solution of the present application will be described mainly by taking interface a as an example of a viewfinder interface being recorded.

In some other embodiments, the beautifying effect in interface a may be the result of the mobile phone 100 intelligently setting the beautifying effect according to the switching of the multi-mirror mode after adopting the solution of the present application.

Exemplarily, in a scenario, the first camera may be a front camera, then interface a may be the viewfinder interface 621 shown in (a) in FIG. 6D , and the first preview image may be the viewfinder interface 621 included A preview image 622, the preview image 622 is obtained after the mobile phone 100 adds the first beautification effect (such as 6-level beautification) to the image collected by the front camera.

Exemplarily, in another scenario, the first camera may also be a rear camera, then interface a may be the viewfinder interface 623 shown in (b) in FIG. 6D , and the first preview image may be the viewfinder interface 623 includes a preview image 624, and the preview image 624 is obtained after the mobile phone 100 adds the first beautification effect (such as 6-level beautification) to the image captured by the rear camera.

S612. The mobile phone 100 displays multiple mode options on the interface a in response to the user's operation 1 on the interface a. Wherein, a plurality of mode options corresponds to a plurality of multi-mirror modes one by one.

Before S612, the mobile phone 100 may receive the user's operation 1 on the interface a.

S613. The mobile phone 100 displays interface b in response to the user's selection operation on mode option 1. Mode option 1 corresponds to the mode in which the second camera and the third camera are used to capture images. Interface b is a viewfinder interface for using the second camera and the third camera to capture images. Interface b includes the second image acquired by processing the second camera. The second preview image and the third preview image obtained by processing the third image captured by the third camera. The preview images captured by the rear camera in the second preview image and the third preview image have no beautification effect added.

Before S613, the mobile phone 100 may receive a user's selection operation on mode option 1.

For the specific implementation of switching the multi-mirror mode (such as switching from the mode of using a single camera to capture images in S612-613 to the mode of using two cameras to capture images), please refer to the relevant description in the first embodiment above, and will not repeat them here . In addition, for the convenience of description, the operation of triggering the mobile phone 100 to switch from capturing images with a single camera to capturing images with two cameras (the second camera and the third camera) may be referred to as the first operation. For example, the user's selection operation on mode option 1 is the first operation. Also for the convenience of description, the interface b may be referred to as the second interface.

Wherein, the mode option 1 may correspond to the front and rear dual-mirror mode, that is, the second camera may be a front camera, and the third camera may be a rear camera. Correspondingly, interface b is the viewfinder interface of the front and rear dual-mirror mode. Further, for different first cameras, the result of smartly setting the beautification effect on the mobile phone 100 is as follows:

In the first type, the first camera is a front camera.

In the front and rear dual-lens mode, the rear camera does not support beautification, and the third image captured by the third camera cannot use the beautification effect. At the same time, if the first camera is a front camera, the second image captured by the second camera may continue to use the first beautifying effect. That is to say, the first camera is a front camera, the second camera is a front camera, and the third camera is a rear camera. Interface b includes the second preview image and the third preview image, and the second preview image is added with the second preview image. One beautification effect, the third preview image has no beautification effect added. That is, the image captured by the front camera follows the beautifying effect before switching, while the image captured by the rear camera does not use the beautifying effect.

Exemplarily, the interface a is the viewfinder interface 621 of the single front mode shown in (a) in FIG. The viewfinder interface 625 of the dual-lens mode, that is, the viewfinder interface 625 is interface b. The viewing interface 625 includes a preview image 627 and a preview image 626, the preview image 627 is a second preview image, and the preview image 626 is a third preview image. The preview image 627 has the first beautification effect added, and the preview image 626 has no beautification effect added.

In the second type, the first camera is a rear camera.

In the front and rear dual-lens mode, the rear camera does not support beautification, and the third image captured by the third camera cannot use the beautification effect. At the same time, if the first camera is a rear camera, the second image captured by the second camera cannot inherit the beautification effect of switching the front and rear cameras. That is to say, the first camera is a rear camera, the second camera is a front camera, and the third camera is a rear camera, interface b includes the second preview image and the third preview image, then the second preview image and the third preview image None of the preview images have beautification effects added. That is, the image captured by the front camera does not use the beautification effect, and the image captured by the rear camera no longer uses the beautification effect before switching.

Exemplarily, interface a is the viewfinder interface 623 shown in (b) of FIG. 6D in the single rear mode. After switching to the front and rear dual-mirror mode, the mobile phone 100 can display the front and rear viewfinder interface 623 shown in (b) in FIG. 6E The viewfinder interface 628 of the dual-lens mode, that is, the viewfinder interface 628 is interface b. The viewing interface 628 includes a preview image 630 and a preview image 629, the preview image 630 is a second preview image, and the preview image 629 is a third preview image. Wherein, neither the preview image 630 nor the preview image 629 has a beautifying effect added.

Wherein, mode option 1 may correspond to a picture-in-picture mode, the second camera may be a front camera, and the third camera may be a rear camera. Correspondingly, interface b is the viewfinder interface of the front and rear dual-mirror mode. Furthermore, for different first cameras, the mobile phone 100 intelligently sets the beautification effect to be different, which is similar to the front and rear dual-lens mode. For the specific principle, please refer to the previous description about the intelligent setting of the beauty effect in the front and rear dual-mirror mode, which will not be repeated here, but only the following two examples are used to illustrate.

Example 1, the first camera is a front camera, and interface a may be the viewfinder interface 621 of the single front mode shown in (a) in FIG. 6D . After switching to the picture-in-picture mode, the mobile phone 100 may display The viewfinder interface 631 of the picture-in-picture mode shown in (a), that is, the viewfinder interface 631 is interface b. The viewfinder interface 631 includes a preview image 632 and a preview image 633 . The preview image 632 is a second preview image, and the preview image 633 is a third preview image. Wherein, the preview image 632 has the first beautifying effect added, and the preview image 633 has no beautifying effect added.

Example 2, the first camera is a rear camera, interface a is the viewfinder interface 623 of the single rear mode shown in (b) in Figure 6D, after switching to the picture-in-picture mode, the mobile phone 100 can display the The viewfinder interface 634 of the picture-in-picture mode shown in (b), that is, the viewfinder interface 634 is interface b. The viewing interface 634 includes a preview image 635 and a preview image 636 , the preview image 635 is a second preview image, and the preview image 636 is a third preview image. Wherein, neither the preview image 635 nor the preview image 636 has a beautifying effect added.

Among them, the mode option 1 can correspond to the rear dual-mirror mode, that is, the second camera and the third camera are both rear cameras. Correspondingly, interface b is the viewfinder interface of the rear-rear dual-mirror mode. Furthermore, if the images collected by the two rear cameras in the rear-rear dual-mirror mode do not support beauty, no matter whether the first camera is a front camera or a rear camera, neither the second preview image nor the third preview image is added beauty.

Exemplarily, taking the first camera as a rear camera as an example, the interface a is the viewfinder interface 623 of the single rear mode shown in (b) in FIG. The viewfinder interface 204d shown in (b) in FIG. 2D is displayed, that is, the viewfinder interface 204d is interface b. The viewing interface 204d includes a preview image 205d and a preview image 206d, the preview image 205d is a second preview image, and the preview image 206d is a third preview image. Since none of the rear cameras in the rear-rear dual-mirror mode supports beautification, the beautification effect of switching the front-facing camera cannot be applied to the rear-rear dual-mirror mode. That is, neither the preview image 205d nor the preview image 206d has a beautification effect added.

Further, in some embodiments, after switching from the mode of capturing images with a single camera to the mode of capturing images with two cameras, the mobile phone 100 can intelligently add a beauty effect to the images captured by different cameras. Then, the mobile phone 100 can switch back to the mode of using a single camera to collect images again. For this situation, in this embodiment, the video shooting method also includes:

S614. The mobile phone 100 displays multiple mode options on the interface b in response to the user's operation 1 on the interface b.

S615. The mobile phone 100 displays an interface c in response to the user's selection operation on mode option 2. Mode option 2 corresponds to the mode of using the fourth camera to capture images, and interface c is a viewfinder interface using the fourth camera to record video. Interface c includes a fourth preview image displayed in full screen, and the fourth preview image is obtained by mobile phone 100 adding the first beauty effect to the fourth image captured by the fourth camera.

Wherein, the fourth camera may be the same as or different from the first camera. For example, the first camera is a rear main camera, and the fourth camera may be a rear main camera or a front camera.

Through the above steps S614-S615, the mobile phone 100 can return from the mode using two cameras to collect images to the mode using a single camera to collect images again, and interface c can be displayed after switching. In interface c, the first beauty effect can be added to the images captured by a single camera. In addition, for the convenience of description, interface c may be referred to as the third interface, and the operation of triggering the mobile phone 100 to switch from using two cameras to collect images to using a single camera to collect images (such as the user's selection operation for mode option 2) is called the third interface. Two operations.

Exemplarily, taking interface b as the viewfinder interface 625 shown in (a) in FIG. 6E as an example, after switching to the single front mode, the mobile phone 100 may display the viewfinder interface 621 shown in (a) in FIG. 6D , that is, the viewfinder interface 621 is interface c. The preview image 622 in the viewfinder interface 621 is added with the first beauty effect, that is, the preview image 622 is a fourth preview image.

In summary, using the method of this embodiment, the mobile phone 100 can switch from the mode of capturing images with a single camera to the mode of capturing images with two cameras in the viewfinder interface before recording or in the viewfinder interface that is recording. Finally, intelligently set the beautification effect of the images captured by the two cameras respectively. Thereby improving the rationality of beauty settings.

Scenario 2, switching from using one front camera and one rear camera to capture images (such as front and rear dual-mirror mode or picture-in-picture mode) to using two rear cameras to capture images (such as rear and rear dual-mirror mode).

Please refer to FIG. 6G , which is a flow chart of a video shooting method provided by the embodiment of the present application, which can be applied to the mobile phone 100 . In this embodiment, scene 2 is mainly taken as an example to illustrate the specific implementation of intelligently setting the beautifying effect.

As shown in Figure 6G, the video shooting method of this embodiment may include:

S641. The mobile phone 100 displays an interface a, where the interface a is a viewfinder interface for video recording in a front-rear dual-mirror mode or a picture-in-picture mode. The interface a includes a first preview image and a fifth preview image. The first preview image is obtained by the mobile phone 100 after adding a first beautifying effect to the first image captured by the first camera, and the second preview image does not add a beautifying effect.

Exemplarily, the interface a may be the viewfinder interface 625 of the front and rear dual-mirror mode shown in (a) in FIG. Preview image 626 is a fifth preview image. The preview image 627 has the first beautification effect added, and the preview image 626 has no beautification effect added.

That is to say, in this embodiment, in the front and rear dual-lens mode before switching, the first beauty effect is added to the image captured by the front camera. Similarly, the beautifying effect in the interface a may be set according to the user's operation on the beautifying control and the beautifying effect control, or may be intelligently set according to the switching of the multi-mirror mode after adopting the solution of this application.

S642. The mobile phone 100 displays multiple mode options on the interface a in response to the user's operation 1 on the interface a. Wherein, a plurality of mode options corresponds to a plurality of multi-mirror modes one by one.

S643. The mobile phone 100 responds to the user's selection operation on mode option 1, and displays interface b. Mode option 1 corresponds to the rear dual mirror mode, and interface b is the viewfinder interface for recording in the rear dual mirror mode. Interface b includes a second preview image and a third preview image, the second preview image is obtained by the mobile phone 100 processing the second image collected by the second camera, and the third preview image is obtained by the mobile phone 100 processing the third image collected by the third camera . No beautification effect is added to the second preview image and the third preview image.

Since the rear and rear dual-mirror mode does not support beauty at all, after switching from the front and rear dual-mirror mode or the picture-in-picture mode to the rear and rear dual-mirror mode, the mobile phone 100 needs to turn off the beauty effect of the front camera before switching (as shown in Section - beautifying effect).

Exemplarily, the interface a is the viewfinder interface 625 of the front and rear dual-mirror mode shown in (a) in FIG. is a preview image 626, and the preview image 626 does not have the first beauty effect. After switching to the rear-rear dual-mirror mode, the mobile phone 100 may display the viewfinder interface 204d shown in (b) of FIG. 2D , that is, the viewfinder interface 204d is interface b. The viewing interface 204d includes a preview image 205d and a preview image 206d, the preview image 205d is a second preview image, and the preview image 206d is a third preview image. Since neither of the rear cameras in the rear-rear dual-mirror mode supports beautification, neither the preview image 205d nor the preview image 206d has a beautification effect added.

Further, in some embodiments, after switching from using one front camera and one rear camera to collect images to using two rear cameras to collect images, the mobile phone 100 can intelligently turn off the beautification effect. Then, the mobile phone 100 can switch back to using a front camera and a rear camera to collect images again. For this situation, in this embodiment, the video shooting method also includes:

S644. The mobile phone 100 displays multiple mode options on the interface b in response to the user's operation 1 on the interface b.

S645. The mobile phone 100 displays an interface d in response to the user's selection operation on mode option 3. Interface d is the viewfinder interface of the front and rear dual-mirror mode or the picture-in-picture mode. Interface d includes a sixth preview image and a seventh preview image, the sixth preview image is obtained by adding the first beauty effect to the sixth image captured by the sixth camera, and the seventh preview image is obtained by processing the seventh image captured by the seventh camera. image obtained. The sixth camera is the front camera, the seventh camera is the rear camera, and the seventh preview image has no beautification effect added.

In other words, mode option 3 corresponds to the front and rear dual-mirror mode or the picture-in-picture mode.

Wherein, the display layout of the sixth preview image and the seventh preview image on the interface d may be the same as the display layout of the first preview image and the fifth preview image on the interface a. Exemplarily, all are split-screen layouts or all are picture-in-picture layouts. Alternatively, the display layout of the sixth preview image and the seventh preview image on interface d may be the same as the display layout of the first preview image and the fifth preview image on interface a. Exemplarily, the sixth preview image and the seventh preview image have a split-screen layout on interface d, and the first preview image and fifth preview image have a picture-in-picture layout on interface a. For example, interface a is the viewfinder interface 625 of the front and rear dual-mirror mode shown in (a) in FIG. 6E , and interface d is the viewfinder interface 631 of the picture-in-picture mode shown in (a) in FIG. 6F . For another example, the sixth preview image and the seventh preview image are in a picture-in-picture layout on the interface d, and the first preview image and the fifth preview image are in a split-screen layout on the interface a. For example, interface a is the viewfinder interface 631 in the picture-in-picture mode shown in (a) in FIG. 6F , and interface d is the viewfinder interface 625 in the front and rear dual-mirror mode shown in (a) in FIG. 6E .

In this embodiment, after switching from using one front-facing camera and one rear-facing camera to capture images using two rear-facing cameras, the mobile phone 100 can cancel the beauty effect; and then switch back to using one front-facing camera After collecting images with a rear camera, the mobile phone 100 may display interface d. In interface d, you can resume adding beauty effects to images captured by the front camera. In addition, for the convenience of description, interface d can also be referred to as the fourth interface, which triggers the operation of the mobile phone 100 to switch from using two rear cameras to collect images to adopt one front camera and one rear camera to collect images (such as the user's mode option 3) can be referred to as a third operation.

Exemplarily, the interface b is the viewfinder interface 204d of the rear-rear dual-mirror mode shown in (b) in FIG. After the drawing mode, the mobile phone 100 may display the viewfinder interface 631 shown in (a) of FIG. 6F. The viewfinder interface 631 includes a preview image 632 and a preview image 633, the preview image 632 is the sixth preview image, and the preview image 633 is the seventh preview image. The first beauty effect is added to the preview image 632 .

To sum up, with the method of this embodiment, the mobile phone 100 can switch from using one front camera and one rear camera to collect images, and switch to using two After the rear camera captures the image, it intelligently turns off the beautification effect. Thereby improving the rationality of beauty settings.

In some embodiments of the

above scenarios

1 and 2, after the mobile phone 100 intelligently turns off all or part of the beautifying effects of the images captured by the camera, the mobile phone 100 may further display prompt 1 on the interface b. The prompt 1 is used to indicate that beauty is turned off.

Exemplarily, the interface a is the viewfinder interface 623 in the single rear mode shown in (b) of FIG. 6D . The first beauty effect is added to the preview image 624 in the viewfinder interface 623, that is, the first beauty effect is added to the image captured by the rear camera. Then, the mobile phone 100 is switched to the front and rear dual-mirror mode, and the interface b may be the viewfinder interface 651 shown in FIG. 6H . The viewfinder interface 651 includes a preview image 652 , a preview image 653 and a prompt 654 . No beautification effect is added to the preview image 651 and the preview image 652, that is, the first beautification effect is turned off. Prompt 654 is specifically: when two cameras are used to record video, the rear camera does not support beautification, which is used to prompt that beautification has been turned off. That is, prompt 654 is prompt 1 .

It should be noted that during a video recording process from entering the multi-camera recording mode to exiting the multi-camera recording mode, the mobile phone 100 will only display a prompt 1 when the beauty effect is turned off for the first time during the process of intelligently setting the beauty effect. It will no longer be displayed after that. This avoids affecting the preview.

Scenario 3, switching from capturing images with one front camera and one rear camera to capturing images with a single camera.

Wherein, the mode of adopting a front camera and a rear camera to collect images can be a front and rear dual-mirror mode or a picture-in-picture mode. In the description of Scene 3 below, the front and rear dual-mirror mode is mainly used as an example to illustrate the principle. The principle of the picture-in-picture mode is similar, and will not be repeated in this article.

Before switching, it is the front and rear dual-mirror mode, and the first beauty effect is added to the images collected by the front camera. If it is the single front mode after switching, you can continue to use the first beauty effect. That is, in the viewfinder interface after switching, the first beauty effect is added to the preview image. If it is a single rear mode after switching, the first beautifying effect will be cancelled. That is, in the viewfinder interface after switching, the first beauty effect is not added to the preview image.

Exemplarily, before the switch is the front and rear dual-mirror mode, and the first beauty effect is added to the image captured by the front camera, then the mobile phone 100 can display the viewfinder interface of the front and rear dual-mirror mode shown in (a) in FIG. 6E 625. The first beauty effect is added to the preview image 627 in the viewfinder interface 625, that is, the first beauty effect is added to the image captured by the front camera. If the single front mode is switched, the mobile phone 100 may display a viewfinder interface 621 showing a single rear mode in (a) of FIG. 6D . The first beauty effect is added to the preview image 622 displayed in full screen in the viewfinder interface 621 , that is, the image captured by a single front camera continues to use the first beauty effect. If the switched mode is the front and rear mode, the mobile phone 100 may display the viewfinder interface 203e shown in (b) of FIG. 2E. The preview image 204e displayed in full screen in the viewfinder interface 203e does not have the first beauty effect added. That is, the beauty effect is turned off.

Scenario 4, switching from using two rear cameras to capture images (such as rear and rear dual-mirror mode) to other multi-mirror modes.

In the case of using two cameras to collect images, the rear camera does not support beautification, and the rear dual-lens mode does not support beautification. Therefore, no beautification effect will be added to the preview image in the viewfinder interface of the rear and rear dual-mirror mode. On this basis, after switching to other multi-mirror modes, the beautification effect will still not be added.

Regarding the above scenario 3 and scenario 4, it needs to be explained as follows:

Scene 3 may appear after S613 of Scene 1, that is, after switching from using a single camera to collect images to using a front camera and a rear camera to collect images, then switch to using a single camera to collect images again. For the case that scene 3 appears after S613 of scene 1, it can be processed according to S615; otherwise, it can be processed according to the method in scene 3. In this way, the consistency of the beauty effect of the smart settings can be guaranteed to avoid conflicts.

Similarly, Scene 4 may appear after S613 of Scene 1, that is, after switching from using a single camera to collect images to using two rear cameras, switch to using a single camera to collect images again. For the situation that scene 4 appears after S613 of scene 1, it can be processed according to S615. Alternatively, Scenario 4 may occur after S643 of Scenario 2, that is, after switching from capturing images with one front camera and one rear camera to capturing images with two rear cameras, switching again to using one front camera and one The rear camera captures images. For the situation that scene 4 occurs after S643 of scene 2, it can be processed according to S645. Otherwise, proceed as in Scenario 4. In this way, the consistency of the beauty effect of the smart settings can be guaranteed to avoid conflicts.

In addition, since the beautification level cannot be manually set by the user during the recording process, the above-mentioned method of intelligently setting the beautifying effect can realize automatic setting of the beautifying effect during the recording process.

In the foregoing description about the beautification function, for various scenarios, only one or two switching processes are used to illustrate the specific realization of the mobile phone's automatic setting of beautification. In practice, the beautification can also be automatically set during more than two switching processes. The following uses a complete example to illustrate the specific implementation of the mobile phone's automatic setting of beautification during the process of switching the multi-mirror mode multiple times.

Before switching for the first time, the mobile phone collects images through the first camera and displays them in full screen. Among them, the first camera is the rear camera. That is, before the first switch, the recording mode adopted by the mobile phone is the single rear mode. In the single rear mode, after adding the first beautifying effect to the mobile phone, the first interface can be displayed. The first interface is the viewfinder interface of the video recording of the mobile phone. The first interface includes the first preview image displayed in full screen. The first preview image is It is obtained by adding the first beauty effect to the first image captured by the first camera. For example, the first interface is the viewfinder interface 623 shown in (b) of FIG. 6D .

The first interface also includes a first control (such as a mode icon or a panel display control), and the first control is used to trigger the mobile phone to switch the recording mode (ie, the multi-mirror mode).

In single rear mode, the phone can switch the recording mode to front and rear dual mirror mode or picture-in-picture mode through the first control. Specifically, the mobile phone may receive a user's click operation on the first control in the first interface. In response to the click operation, the mobile phone can display multiple options (that is, multiple mode options) on the first interface, and the multiple options correspond to multiple recording modes one by one. The mobile phone may receive a user's selection operation on a first option, the first option is one of multiple options, and the first option corresponds to a front-rear dual-mirror mode or a picture-in-picture mode. The mobile phone can display the second interface in response to the selection operation, the second interface is the viewfinder interface of the mobile phone video, the second interface includes the second preview image and the third preview image, and the second preview image is the first preview image collected by the second camera. The second image is processed without adding a beautifying effect, and the third preview image is obtained after processing the third image captured by the third camera without adding a beautifying effect. That is, in response to the user's selection operation on the first option, the mobile phone can switch to the front and rear dual-mirror mode or the picture-in-picture mode, and in the viewfinder interface after switching, no beauty effect is added to the two preview images. For example, the first interface is the viewfinder interface 623 in single rear mode shown in (b) in FIG. 6D , and the second interface is the viewfinder interface 628 in front and rear dual-mirror mode shown in (b) in FIG. 6E .

After switching to the front and rear dual-mirror mode or the picture-in-picture mode, the mobile phone can also display the first prompt message on the second interface. The first prompt message is used to prompt that when two cameras are used to collect images, all rear cameras None of the collected images support beauty. This allows the user to be prompted for the reason for canceling the filter.

After switching to front and rear dual-mirror mode or picture-in-picture mode, and canceling the beautification, the phone can continue to switch to single front mode or single rear mode. Specifically, the second interface may also include the first control, and after the second interface is displayed, the mobile phone may receive a user's click operation on the first control in the second interface. The mobile phone displays multiple options on the second interface in response to the click operation. The mobile phone receives a user's selection operation on the second option, the second option is one of multiple options, and the second option corresponds to a single front mode or a single rear mode. The mobile phone displays a third interface in response to the selection operation. The third interface is a viewfinder interface for video recordings of the mobile phone. The third interface includes a fourth preview image displayed in full screen, and the fourth preview image is the fourth image collected by the fourth camera. It is obtained after a beauty effect. The fourth camera is a rear camera or a front camera. That is, the mobile phone can switch to the single front mode or the single rear mode in response to the user's selection operation on the second option, and can restore to the beautifying effect before the first switching, that is, the first beautifying effect. For example, the second interface is the viewfinder interface 628 in front and rear dual-mirror mode shown in (b) in FIG. 6E , and the third interface is the viewfinder interface 621 in single front mode shown in (a) in FIG. 6D .

If the fourth camera is a front camera, switch to the single front mode, and after the beautification effect, the mobile phone can continue to switch to the front and rear dual mirror mode or the picture-in-picture mode. Specifically, the third interface may also include the first control, and after the third interface is displayed, the mobile phone may receive a user's click operation on the first control in the third interface. The mobile phone displays multiple options on the third interface in response to the click operation. The mobile phone receives the user's selection operation of the third option, and the third option corresponds to the front and rear dual-mirror mode or the picture-in-picture mode. It should be noted that the recording mode corresponding to the fourth option may be the same as the recording mode corresponding to the first option, for example, both are front and rear dual-mirror modes. Alternatively, the recording mode corresponding to the fourth option may be the same as the recording mode corresponding to the first option. For example, the recording mode corresponding to the fourth option is the picture-in-picture mode, and the recording mode corresponding to the first option is the front and rear dual-mirror mode. In response to the selection operation, the mobile phone displays a fourth interface, the fourth interface is a viewfinder interface for video recording of the mobile phone, and the fourth interface includes a fifth preview image and a sixth preview image. The fifth preview image is obtained by adding the first beauty effect to the fifth image captured by the fifth camera, where the fifth camera is a front camera. The sixth preview image is obtained after processing the fifth image captured by the sixth camera without adding a beautification effect, and the sixth camera is a rear camera. That is to say, after switching from single front mode to front and rear dual mirror mode or picture-in-picture mode, the image captured by the front camera can continue to use the first beautification effect before the switch, while the image captured by the rear camera will not add beautification. color effect. For example, the third interface is the viewfinder interface 621 in the single front mode shown in (a) in FIG. 6D , and the fourth interface is the viewfinder interface 625 in the front and rear dual-mirror mode shown in (a) in FIG. 6E .

After switching from the single front mode to the front and rear dual-mirror mode or the picture-in-picture mode, the mobile phone can continue to switch to the rear and rear dual-mirror mode. Specifically, the recording mode also includes a rear-rear dual-mirror mode, and the fourth interface may also include the first control. After the fourth interface is displayed, the mobile phone may receive a user's click operation on the first control in the fourth interface. The mobile phone displays multiple options on the fourth interface in response to the click operation. The mobile phone can receive the user's selection operation on the fourth option, the fourth option is one of multiple options, and the fourth option corresponds to the rear and rear dual-mirror mode. In response to the selection operation, the mobile phone displays a fifth interface, the fifth interface is a viewfinder interface for video recording of the mobile phone, and the fifth interface includes the seventh preview image and the eighth preview image. The seventh preview image is obtained after processing the seventh image captured by the seventh camera without adding a beautifying effect, and the eighth preview image is obtained after processing the eighth image captured by the eighth camera without adding a beautifying effect of. Among them, both the seventh camera and the eighth camera are rear cameras. That is to say, after switching from the front and rear dual-mirror mode or the picture-in-picture mode to the rear and rear dual-mirror mode, the images captured by the two rear cameras will not have a beautification effect. For example, the fourth interface is the viewfinder interface 625 in the front and rear dual-mirror mode shown in (a) in FIG. 6E , and the fifth interface is the viewfinder interface 204d in the rear and rear dual-mirror mode shown in (b) in FIG. 2D .

Or, after switching to the front and rear dual-mirror mode or picture-in-picture mode, and canceling the beautification, and then continuing to switch to the single front mode or single rear mode, and restoring the beautification effect, the phone can continue to switch to the rear dual-lens mode. mirror mode. Specifically, the recording mode also includes a rear-rear dual-mirror mode, and the third interface also includes a first control. After the third interface is displayed, the mobile phone receives the user's click operation on the first control in the third interface. The mobile phone displays multiple options on the third interface in response to the click operation. The mobile phone receives a user's selection operation on the fourth option, where the fourth option is one of multiple options, and the fourth option corresponds to a rear-rear dual-mirror mode. In response to the selection operation, the mobile phone displays a sixth interface, the sixth interface is a viewfinder interface for video recording of the mobile phone, and the sixth interface includes a ninth preview image and a tenth preview image. The ninth preview image is obtained after processing the ninth image captured by the ninth camera without adding a beautifying effect. The tenth preview image is obtained after processing the tenth image collected by the tenth camera without adding a beautifying effect. Both the ninth camera and the tenth camera are rear cameras. That is to say, after switching from single front mode or single rear mode to rear and rear dual-mirror mode, the images captured by the two rear cameras will not add beauty effects. For example, the third interface is the viewfinder interface 621 in the single front mode shown in (a) of FIG. 6D , and the viewfinder interface 204d in the rear-rear dual-mirror mode shown in (b) in FIG. 2D .

Embodiment 3, filter function.

A video shooting method provided in the embodiment of the present application can be applied to the mobile phone 100 . Wherein, in the multi-mirror recording mode, in the viewfinder interface before recording, the mobile phone 100 may display multiple filter options for the user to select a filter in response to the user's operation (such as clicking) on the filter icon in the viewfinder interface. Multiple filter options correspond to various filters one by one. Then, the mobile phone 100 may set a corresponding filter in response to the user's selection operation on the filter option. In this way, the filter setting can be completed before recording in the multi-mirror recording mode.

Exemplarily, the filter icon is the icon 233 in the viewfinder interface 201c shown in (a) of FIG. 2C . The mobile phone 100 may display the viewfinder interface 201c shown in (a) in FIG. 7A in response to the user's click operation on the icon 233 in the viewfinder interface 201c shown in (a) in FIG. 2C . The viewfinder interface 201c shown in (a) of FIG. 7A includes four kinds of filter options (as shown in the dotted box 701 ), and each filter option displays a filter effect. Then, the mobile phone 100 can receive the user's selection operation on the filter. The mobile phone 100 may display the viewfinder interface 201c shown in (b) in FIG. 7A in response to the user's selection operation on the filter option 702 in the viewfinder interface 201c shown in (a) in FIG. 7A . In (b) of FIG. 7A , the preview image in the viewfinder interface 201c shown in FIG.

In some embodiments, the plurality of filter options includes a no-filter option. For example, the filter option 703 in the viewfinder interface 201c shown in (a) of FIG. 7A is an option of no filter. The mobile phone 100 may turn off the filter in response to the user's selection operation on the option without filter.

In practice, when more than two cameras are used to collect preview images, it is difficult to use a unified filter to match the preview images collected by more than two cameras. For example, in the front and rear dual-lens mode, the front camera captures portraits, and the rear camera captures landscapes. Typically, the need for adding filters to portraits is different than to adding filters to landscapes. Therefore, it is difficult to process portraits and landscapes at the same time with one filter.

Based on this, in some embodiments, only the single front mode and the single rear mode support adding filters, while the front and rear dual-mirror mode, the rear-rear dual-mirror mode and the picture-in-picture mode do not support filters. Correspondingly, the mobile phone 100 may display available filter icons in the viewfinder interface before recording in the single front mode and the single rear mode. For example, the viewfinder interface 201c shown in (a) in FIG. 2C is the viewfinder interface before recording in the single front mode, and the filter icon is blacked out, that is, available. The mobile phone 100 may not display the filter icon, or display the filter icon in an unavailable state (such as greyed out) in the viewfinder interface before recording in the front and rear dual-mirror mode, the rear-rear dual-mirror mode, and the picture-in-picture mode. For example, the viewfinder interface 203a shown in (b) in FIG. 2A is the viewfinder interface before recording in the front-rear dual-mirror mode, and the filter icon 217 is grayed out, that is, unavailable.

In other embodiments, the front and rear dual-mirror mode, the rear-rear dual-mirror mode and the picture-in-picture mode can also support filters. Exemplarily, the mobile phone 100 includes some filters suitable for the front and rear dual-mirror mode, the rear-rear dual-mirror mode and the picture-in-picture mode. Correspondingly, the mobile phone 100 may also display a filter icon in the viewfinder interface during recording in the front and rear dual-mirror mode, the rear-rear dual-mirror mode, and the picture-in-picture mode. It should be noted that the filters applicable to the front-to-back dual-mirror mode, the rear-to-rear dual-mirror mode, and the picture-in-picture mode are generally all applicable to the single front mode and single rear mode. However, in some specific implementations, the filters applicable to the front and rear dual-mirror mode, the rear-rear dual-mirror mode, and the picture-in-picture mode may also be partially applicable to the single front mode and single rear mode, or not applicable at all. The single pre-mode and the single post-mode are not specifically limited in this embodiment of the present application.

That is to say, the single front mode, single rear mode, front and rear dual mirror mode, rear rear dual mirror mode, and picture-in-picture mode support filters, including several possibilities as shown in Table 1 below.

Table 1

Based on the several possibilities shown in Table 1 above, this embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can automatically set the filter of the multi-mirror mode after the switch according to the filter used before the switch. As shown in Figure 7B, the video shooting method of the embodiment of the present application may include:

S711. The mobile phone 100 displays an interface a, where the interface a is a viewfinder interface during sub-mode 1 recording. The interface a includes a preview image of the added filter a.

Exemplarily, taking sub-mode 1 as a single rear mode as an example, interface a may be the viewfinder interface 721 shown in FIG. 722. In addition, a filter a is added to the preview image 722 , that is, the straight line from the upper right to the lower left indicates the effect of the filter a.

Wherein, the filter a may be added by the mobile phone 100 in response to the user selecting a filter option corresponding to the filter a in the sub-mode 1 before video recording. The process of adding a filter has been explained in the previous article, so I won’t go into details here. After the filter a is added, the mobile phone 100 can enter the viewfinder interface in sub-mode 1 recording, ie, interface a, in response to the user's operation of starting video recording (such as clicking the start recording control).

Alternatively, the filter a is added during at least one execution of the scheme shown in FIG. 7B , such as added in S714 or S715 , for details, please refer to the description below, and no detailed description will be given here.

S712. The mobile phone 100 responds to operation 1 on the user interface a, and displays multiple mode options on the interface a. Wherein, a plurality of mode options corresponds to a plurality of multi-mirror modes one by one.

For the switching process from sub-mode 1 to sub-mode 2, reference may be made to the relevant description in the first embodiment above, and details will not be repeated here.

S713. The mobile phone 100 displays interface b in response to the user's selection operation on mode option 1. Mode option 1 corresponds to sub-mode 2, and interface b is the viewfinder interface during sub-mode 2 recording. Wherein, if the sub-mode 2 does not support filters, interface b includes preview images without added filters.

That is, submode 1 supports filters and submode 2 does not. In this case, after the mobile phone 100 switches to sub-mode 2, filter a is automatically canceled.

As an example, take sub-mode 1 as a single rear mode and sub-mode 2 as an example with front and rear dual mirrors. Among them, the single rear mode supports filters, and the front and rear dual mirror mode does not support filters, as shown in the first possibility in Table 1 above. After switching to the front and rear dual-mirror mode, the mobile phone 100 may display the viewfinder interface 731 shown in (a) of FIG. 7D , that is, the viewfinder interface 731 is interface b. No filter is added to the preview image 732 and the preview image 733 in the viewfinder interface 731 . In short, the filter a used in the single front mode will no longer be used after switching to the front and rear dual mirror mode.

In some embodiments, when the filter a is canceled, the mobile phone 100 may also display a prompt 1 on the interface b, where the prompt 1 is used to prompt that the filter has been cancelled. For example, interface b may be the viewfinder interface 731 shown in (b) in FIG. 7D, and the viewfinder interface 731 shown in (b) in FIG. Switch to No Filter Effect for you" to indicate that the filter has been cancelled. That is, prompt 734 is prompt 1 .

S714. The mobile phone 100 displays interface b in response to the user's selection operation on mode option 1. Mode option 1 corresponds to sub-mode 2, and interface b is the viewfinder interface during sub-mode 2 recording. Wherein, if the sub-mode 2 supports the filter but does not support the filter a, the interface b includes a preview image without a filter; or, the interface b includes a preview image with a filter b added. Filter b is the user's preferred filter in sub-mode 2.

Among them, in the scene where both sub-mode 1 and sub-mode 2 support filters, if the filters supported by sub-mode 1 and sub-mode 2 are different, it may appear that sub-mode 1 supports filter a, but sub-mode 2 does not. The case of filter a is supported.

As an example, take sub-mode 1 as a single rear mode and sub-mode 2 as an example with front and rear dual mirrors. If the single rear mode supports filters and the front and rear dual-lens mode supports filters as shown in the second to fourth possibilities in Table 1 above, it is possible that sub-mode 1 supports filter a, but sub-mode 2 The case of filter a is not supported.

In this case, after the mobile phone 100 switches to the sub-mode 2, the filter can be set in the following two ways.

One way is to automatically cancel the filter. The first method is the same as the processing in S713, for details, please refer to the description in S713, which will not be repeated here.

Method 2: Add filter b automatically. Filter b is a filter supported by sub-mode 2, and it is also a filter preferred by users in sub-mode 2.

Wherein, filter b specifically refers to a filter that was manually added by the user in sub-mode 2 last time and then used for recording in sub-mode 2, and has not been manually closed by the user in sub-mode 2 since then. Wherein, the user manually adding a filter refers to a manner in which the mobile phone 100 adds a filter in response to a user's selection operation on a filter option. For example, the manner shown in (a) in FIG. 7A.

Before describing the second method, the process of determining the filter b by the mobile phone 100 will be described with reference to FIG. 7E.

Specifically, after the user manually adds a filter for sub-mode 2 (such as the front and rear dual-mirror mode) each time, and then triggers the mobile phone 100 to start recording in sub-mode 2, the mobile phone 100 can record the added filter as the user's sub-mode The preferred filter in mode 2 (such as front and rear dual mirror mode).

Exemplarily, taking the sub-mode 2 as an example of the front and rear dual-lens mode, before a certain video recording, the mobile phone 100 may display the viewfinder interface 203a shown in (b) in FIG. 2A . Then, in response to the user's selection operation of the filter option of filter b, the mobile phone 100 may display a viewfinder interface 741 shown in (a) in FIG. Afterwards, the mobile phone 100 may display the viewfinder interface 742 shown in (b) of FIG. 7E in response to the operation of starting recording. A filter b is also added to the preview image of the viewfinder interface 742 , that is, the filter b is used for the video in the front and rear dual-lens mode. At this time, the filter b can be recorded as the filter preferred by the user in the front and rear dual-lens mode.

After the mobile phone 100 records the user's preferred filter in sub-mode 2, if the user turns off the recorded filter in sub-mode 2, the mobile phone 100 will update the user's preferred filter in sub-mode 2 to none.

Exemplarily, still taking sub-mode 2 as the front and rear dual-mirror mode as an example, after the mobile phone 100 records the user's preferred filter in the front and rear dual-mirror mode, if in the viewfinder interface before recording in sub-mode 2, the mobile phone 100 In response to the user's selection operation on the option without filter, the filter is turned off. The mobile phone 100 updates the filter preferred by the user in sub-mode 2 to none.

Or, after the mobile phone 100 records the user's preferred filter in sub-mode 2, if the user reselects a filter (such as filter c) in sub-mode 2, and then triggers the mobile phone 100 to start recording in sub-mode 2, The mobile phone 100 may update the user's preferred filter in sub-mode 2 (eg, front and rear dual-mirror mode) to the latest added filter (eg, filter c).

Through the above method, the mobile phone 100 can maintain the corresponding relationship between each multi-mirror mode and the filter preferred by the user in the multi-mirror mode. Exemplarily, the mobile phone 100 maintains a correspondence table as shown in Table 2 below:

Table 2

多镜子模式multi-mirror mode	用户偏好的滤镜user-preferred filters
单前置模式single front mode	滤镜afilter a
单后置模式single rear mode	无none
前后双镜模式Front and rear dual mirror mode	滤镜bfilter b
后后双镜模式rear dual mirror mode	无none
画中画模式picture-in-picture mode	滤镜dfilter d

It should be understood that with continuous use of the multi-mirror recording mode, the user's selection of filters will change accordingly, and correspondingly, the user's preferred filter in each multi-mirror mode will also change accordingly. That is, Table 1 will be constantly updated and changed.

In the second manner, the mobile phone 100 can automatically add the filter preferred by the user in the sub-mode 2 as the filter of the sub-mode 2. In this way, filters can be automatically added according to user preferences, improving the rationality of adding filters during recording. It should be noted that if the user prefers no filter in sub-mode 2, after switching to sub-mode 2, the mobile phone 100 only needs to cancel the filter.

S715. The mobile phone 100 responds to the user's selection operation on mode option 1, and displays interface b. Mode option 1 corresponds to sub-mode 2, and interface b is the viewfinder interface during sub-mode 2 recording. Wherein, if sub-mode 2 supports filters and supports filter a, interface b includes a preview image of filter a.

Among them, in the scene where both sub-mode 1 and sub-mode 2 support filters, if the filters supported by sub-mode 1 and the filters supported by sub-mode 2 have the same filter, it may appear that both sub-mode 1 and sub-mode 2 support filters a situation.

As an example, take sub-mode 1 as a single rear mode and sub-mode 2 as an example with front and rear dual mirrors. If the single rear mode supports filters and the front and rear dual mirror mode supports filters as shown in the second, third and fifth possibilities in Table 1 above, both sub-mode 1 and sub-mode 2 may appear. The case of filter a is supported.

In this case, after the mobile phone 100 switches to the sub-mode 2, the filter a can be used.

Exemplarily, sub-mode 1 is a single rear mode, and sub-mode 2 is a front-rear dual-mirror mode as an example. If the effect of filter a is as shown in the viewfinder interface 721 in FIG. 7C , which is a straight line from upper right to lower left, the mobile phone 100 can display the viewfinder interface 751 shown in FIG. 7F after switching to the front and rear dual-mirror mode. A filter a is also added to the preview image in the viewfinder interface 751 .

In the above-mentioned embodiment shown in FIG. 7B , only one switching process during recording is used to illustrate the specific implementation of automatically setting filters in the process of switching the multi-mirror mode of the mobile phone 100 . It should be understood that, in actual implementation, the mobile phone 100 may use the embodiment shown in FIG. 7B to set a filter for each switching in the multiple switching processes.

In some embodiments, after canceling the filter in S713 or S714, after switching back to sub-mode 1 again, the filter a can be resumed. As shown in Figure 7B, the method may also include:

S716. The mobile phone 100 displays multiple mode options on the interface b in response to operation 1 on the user interface b.

S717. The mobile phone 100 displays an interface c in response to the user's selection operation on mode option 2. Mode option 2 corresponds to sub-mode 1, and interface c is the viewfinder interface during sub-mode 1 recording. Wherein, the interface c includes a preview image with the filter a added.

To sum up, with the method of this embodiment, on the one hand, during the recording, the mobile phone 100 can automatically set the filter after switching the multi-mirror mode, so as to make up for the deficiency that the user cannot select the filter during the recording. On the other hand, the mobile phone 100 can automatically set the filter according to whether the multi-mirror mode supports filters before and after switching, or further combine the user's preferred filter in the multi-mirror mode after switching, which can improve the rationality of setting the filter. sex.

In addition, since the user cannot manually select a filter during recording, the embodiment shown in FIG. 7B can be used to automatically set the filter during the recording process. However, in actual implementation, it is not limited to recording, and filters can also be automatically set during the switching process before recording, and its implementation principle is similar to that during recording. It will not be repeated here.

Embodiment 4, high frame rate recording and/or high resolution recording.

A video shooting method provided in the embodiment of the present application can be applied to the mobile phone 100 . Wherein, in the multi-camera recording mode, in the viewfinder interface before recording, the mobile phone 100 may display multiple setting items for the user to set camera parameters in response to the user's operation (such as clicking) on the setting icon. Wherein, the plurality of setting items include setting items of video resolution (referred to as resolution) and/or video frame rate (referred to as frame rate). In addition, for the convenience of description, the frame rate and/or resolution may be collectively referred to as the acquisition parameters of the camera. Then, the mobile phone 100 can set the resolution in response to the user's selection of the resolution in the resolution setting item; the mobile phone 100 can set the frame rate in response to the user's selection of the frame rate in the frame rate setting item. Therefore, the setting of resolution and frame rate can be completed before recording in multi-lens recording mode.

Exemplarily, the setting icon is the icon 218 in the viewfinder interface 203a shown in (b) of FIG. 2A. The mobile phone 100 may display the setting interface 801 shown in (a) of FIG. 8A in response to the user's click operation on the icon 218 . The setting interface 801 includes a resolution setting item 802 and a frame rate setting item 803 . Then, in response to the user's click operation on the resolution setting item 802, the mobile phone 100 may display a resolution setting panel on the setting interface 801, and the resolution setting panel may be the panel 804 in (b) in FIG. 8A . The panel 804 includes multiple resolution options, and the mobile phone 100 can set the resolution in response to the user's selection operation on any resolution option. Alternatively, the mobile phone 100 may display a frame rate setting panel on the setting interface 801 in response to the user's click operation on the frame rate setting item 803, and the frame rate setting panel may be the panel 805 in (c) in FIG. 8A. The panel 805 includes multiple frame rate options, and the mobile phone 100 can set the frame rate in response to the user's selection operation on any frame rate option.

In addition, recording video at a high resolution (such as a horizontal resolution of 4000 pixels (ie 4K)) and/or a high frame rate (such as 60 frames per second (ie 60fps)) will result in a larger file size. For example, if a single camera is used to record video at 4K and 60fps for 5 minutes, a file of about 1G will be generated. Obviously, if two or more cameras are used to shoot videos of the same duration with the same resolution and frame rate, larger files will be generated.

Based on this, in some embodiments, in the multi-mirror recording mode, the mobile phone 100 only supports recording exceeding the preset resolution threshold (ie, high-resolution recording) and/or supports Recordings that exceed a preset frame rate threshold (i.e. high frame rate recording). However, in the multi-mirror mode using two or more cameras, such as the front and rear dual-mirror mode, the rear-rear dual-mirror mode, and the picture-in-picture mode, the mobile phone 100 only supports recordings that do not exceed the preset resolution threshold and supports video recordings that do not exceed the preset resolution threshold. Recording with frame rate threshold. Usually, a resolution exceeding 1080p (horizontal resolution of 1080 pixels) can be called high resolution, therefore, the preset resolution threshold can be 1080p. And, if it exceeds 30fps, it can be called a high frame rate. Therefore, the preset frame rate threshold can be 30 frames. However, the actual implementation is limited to this.

Further, when the multi-mirror mode of the mobile phone 100 is the front and rear dual-mirror mode, the rear-rear dual-mirror mode, or the picture-in-picture mode, in response to the user's click operation on the setting item of the resolution, it will not display selectable, more than Resolution options for preset resolution thresholds. For example, when the multi-mirror mode is the front and rear dual-mirror mode, the mobile phone 100 may display the panel 804 shown in (b) in FIG. Settings panel. The resolution option 4K in the panel 804 is grayed out, or the panel 804 may not include the resolution option 4K, that is, the resolution 4K cannot be selected. And, when the multi-mirror mode of the mobile phone 100 is the front and rear dual-mirror mode, the rear-rear dual-mirror mode, or the picture-in-picture mode, in response to the user's click operation on the setting item of the frame rate, it will not display selectable, exceeding the preset Frame rate option to set the frame rate threshold. For example, when the multi-mirror mode is the front and rear dual-mirror mode, the mobile phone 100 may display the panel 805 shown in (c) in FIG. Settings panel. The frame rate option 60fps in the panel 805 is grayed out, or the panel 805 may not include the frame rate option 60fps, that is, the frame rate 60fps cannot be selected.

On the contrary, when the multi-mirror mode is the single front mode or the single rear mode, the mobile phone 100 may display selectable images that exceed the preset resolution threshold in response to the user's click operation on the resolution setting item. resolution options. For example, when the multi-mirror mode is the single rear mode, the mobile phone 100 may display the panel 811 shown in (a) in FIG. Settings panel. The resolution option 4K in this panel 811 is optional. And, when the multi-mirror mode is the single front mode or the single rear mode, the mobile phone 100 can display selectable frame rate exceeding the preset frame rate threshold in response to the user's click operation on the setting item of the frame rate. option. For example, when the multi-mirror mode is the single rear mode, the mobile phone 100 may display the panel 812 shown in (b) in FIG. Settings panel. The frame rate option 60fps in this panel 812 is also selectable.

In addition, for the convenience of description, the operation of triggering the mobile phone 100 to display the resolution option and/or the frame rate option may be collectively referred to as a third operation. By displaying the resolution option and/or the frame rate option, the user can be provided with parameter options of the acquisition parameters to be selected, so that the acquisition parameters can be set. That is to say, the third operation may be used to trigger the mobile phone 100 to set collection parameters. And, the preset resolution threshold and/or the preset frame rate threshold may be collectively referred to as the preset parameter threshold, and the resolution options exceeding the preset resolution threshold and/or the frame rate options exceeding the preset frame rate threshold may be collectively referred to as as the first option. Moreover, the first option corresponds to a collection parameter (may be referred to as a third collection parameter) greater than a preset parameter threshold. After the first option is displayed, the mobile phone 100 may receive a user's selection operation on the first option; in response to the selection operation, the mobile phone 100 may set the collection parameter as the third collection parameter.

Based on the resolution and frame rate supported by the mobile phone 100 in different multi-mirror modes, the embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . Wherein, the mobile phone 100 can automatically adjust the resolution and frame rate as the multi-mirror mode is switched before or during the video recording. In the following embodiments, the specific realization of automatically adjusting the resolution and frame rate is mainly described by taking the scene before recording as an example.

In some embodiments, the first interface is displayed before switching, the first interface is a viewfinder interface for video recording in single front mode or single rear mode, and the first interface includes a single camera with a resolution of 1 (also referred to as the first resolution) captured preview image. Wherein, the single camera used before switching may be called the first camera, and the preview image collected by the first camera with a resolution of 1 may also be called the first preview image. In single front mode or single rear mode, the first preview image should be displayed in the first interface in full screen. Then, the mobile phone 100 may receive an operation that triggers the mobile phone 100 to switch to a mode that uses two cameras to collect images (also may be called the first operation). In response to this operation, the mobile phone 100 may switch to a mode that uses two cameras to collect images, such as a front and rear dual-mirror mode, a rear-rear dual-mirror mode, or a picture-in-picture mode. Meanwhile, if the resolution 1 is greater than the preset resolution threshold, the mobile phone 100 may adjust the resolution to resolution 2 (also called the second resolution). Wherein, the resolution 2 is less than or equal to the preset resolution threshold, and the resolution 2 is a default resolution in the multi-lens recording mode, such as 1080p. That is to say, when the resolution 1 is greater than the preset resolution threshold, the mobile phone 100 can display the second interface after switching to the front and rear dual-mirror mode, the rear-rear dual-mirror mode or the picture-in-picture mode. The second interface is The viewfinder interface for video recording in front and rear dual-mirror mode, rear-rear dual-mirror mode, or picture-in-picture mode, and the second interface includes preview images captured by the two cameras at a resolution of 2, respectively. Wherein, the two cameras adopted after switching may be referred to as the second camera and the third camera, the preview image collected by the second camera with a resolution of 2 may be referred to as the second preview image, and the preview image collected by the third camera with a resolution of 2 It can also be called the third preview image.

On the contrary, if the resolution 1 is less than or equal to the preset resolution threshold, the mobile phone 100 can keep the resolution unchanged. That is to say, when the resolution 1 is less than or equal to the preset resolution threshold, the mobile phone 100 can display the third interface after switching to the front and rear dual-mirror mode, the rear and rear dual-mirror mode, or the picture-in-picture mode. The interface is a viewfinder interface for video recording in front and rear dual mirror mode, rear and rear dual mirror mode, or picture-in-picture mode. The third interface includes preview images collected by the two cameras at a resolution of 1 respectively. Wherein, the preview image captured by the second camera with resolution 1 may be called the fourth preview image, and the preview image captured by the third camera with resolution 1 may also be called the fifth preview image.

In some embodiments, the first interface is displayed before switching, and the first interface includes preview images captured by a single camera at a frame rate of 1 (also referred to as the first frame rate). Then, after switching to a mode that uses two cameras to collect images, such as the front and rear dual-mirror mode, the rear and rear dual-mirror mode, or the picture-in-picture mode, if the frame rate 1 is greater than the preset frame rate threshold, the mobile phone 100 can adjust the frame rate to Frame rate 2 (also called second resolution). Wherein, the frame rate 2 is less than or equal to the preset frame rate threshold, and the frame rate 2 is a default frame rate in the multi-lens recording mode, such as 30fps. That is to say, when the frame rate 1 is greater than the preset frame rate threshold, the mobile phone 100 can display the second interface after switching to the front and rear dual-mirror mode, the rear-rear dual-mirror mode or the picture-in-picture mode. Includes preview images captured by both cameras at frame rate 2. Similarly, the preview image captured by the second camera at a frame rate of 2 may be called a second preview image, and the preview image captured by the third camera at a frame rate of 2 may also be called a third preview image.

On the contrary, if the frame rate 1 is less than or equal to the preset resolution threshold, the mobile phone 100 can keep the frame rate unchanged. That is to say, when the frame rate 1 is less than or equal to the preset frame rate threshold, the mobile phone 100 can display the third interface after switching to the front and rear dual-mirror mode, the rear and rear dual-mirror mode, or the picture-in-picture mode. The interface includes preview images captured by the two cameras at frame rate 1 respectively. Wherein, the preview image captured by the second camera at a frame rate of 1 may be called a fourth preview image, and the preview image captured by the third camera at a frame rate of 1 may also be called a fifth preview image.

In addition, for ease of description, resolution 1 and/or frame rate 1 may be collectively referred to as a first acquisition parameter, and resolution 2 and/or frame rate 2 may be collectively referred to as a second acquisition parameter.

In the foregoing embodiments, the specific implementation of automatically adjusting acquisition parameters is mainly described by using only the resolution and the frame rate alone. In some other embodiments, before switching, the resolution 1 and the frame rate 1 can be used to capture images simultaneously. After switching to front and rear dual-mirror mode, rear-rear dual-mirror mode or picture-in-picture mode, if the resolution 1 is greater than the preset resolution threshold, the resolution can be adjusted to resolution 2. Correspondingly, the second interface includes preview images captured by both cameras at a resolution of 2 and a frame rate of 1, wherein the preview image captured by the second camera at a resolution of 2 and a frame rate of 1 may be referred to as a second preview image, The preview image captured by the third camera with resolution 2 and frame rate 1 may be referred to as a third preview image. If the frame rate 1 is greater than the preset frame rate threshold, the frame rate may be adjusted to frame rate 2. Correspondingly, the second interface includes preview images captured by both cameras at a resolution of 1 and a frame rate of 2, wherein the preview image captured by the second camera at a resolution of 1 and a frame rate of 2 may be referred to as a second preview image, The preview image captured by the third camera with resolution 1 and frame rate 2 may be referred to as a third preview image. If the resolution 1 is greater than the preset resolution threshold and the frame rate 1 is greater than the preset frame rate threshold, the frame rate can be adjusted to frame rate 2, and the resolution can be adjusted to resolution 2. Correspondingly, the second interface includes preview images captured by both cameras at a resolution of 2 and a frame rate of 2, wherein the preview image captured by the second camera at a resolution of 2 and a frame rate of 2 may be referred to as a second preview image, The preview image captured by the third camera with resolution 2 and frame rate 2 may be referred to as a third preview image.

If the resolution 1 is less than or equal to the preset resolution threshold, and the frame rate 1 is less than or equal to the preset frame rate threshold, the mobile phone 100 can keep the frame rate and resolution unchanged. Correspondingly, after switching, the mobile phone 100 can display a third interface, the third interface includes preview images captured by both cameras at a resolution of 1 and a frame rate of 1, wherein the second camera uses a resolution of 1 and a frame rate of 1 The preview image collected by the third camera may be called a fourth preview image, and the preview image collected by the third camera with a resolution of 1 and a frame rate of 1 may be called a fifth preview image.

Exemplarily, in the single rear mode, the mobile phone 100 can display the viewfinder interface 821 shown in (a) in FIG. Capture the preview image, that is, the resolution 1 is 4K, and the frame rate 1 is 60fps. It should be understood that the text "acquire preview images at 4K, 60 fps" in the viewfinder interface 821 is only illustrative, and whether to display it can be determined according to requirements in actual implementation. Then, after switching from the single rear mode to the front and rear dual mirror mode, the mobile phone 10 can display the viewfinder interface 822 shown in (b) in FIG. Automatically reduce to 30 frames, that is, the resolution 2 is 1080p, and the frame rate 2 is 30 frames. Similarly, the text in the viewfinder interface 822 "The front and rear dual-lens mode does not support 4K, 60fps, it has been automatically switched to 1080p, 30fps for you" is also schematic, and the actual implementation can also be determined according to actual needs.

In some embodiments, after adjusting the resolution from resolution 1 to resolution 2, and/or adjusting the frame rate from frame rate 1 to frame rate 2, the mobile phone 100 may display prompt 1 on the second interface (also may be referred to as the first prompt message). This prompt 1 is used to indicate that the resolution and/or frame rate have been switched. For example, the prompt 1 is the text in the viewfinder interface 822 shown in (b) of FIG. 8C "The front and rear dual-lens mode does not support 4K, 60fps, it has been automatically switched to 1080p, 30fps for you".

To sum up, using the method of the embodiment of the present application, the mobile phone 100 can switch to a multi-mirror mode that does not support high frame rate and high resolution after switching to a high frame rate and/or high resolution before switching , automatically downgrade high resolutions to default resolutions and high framerates to default framerates. Therefore, the resolution and frame rate can be adaptively adjusted, so that video recording can finally start at a reasonable resolution and/or frame rate. In this way, the mobile phone 100 can reasonably control the size of the video file.

Further, the resolution of the mobile phone 100 is reduced to resolution 2, and if the single front mode or the single rear mode is used again afterwards, the resolution can be restored to resolution 1. And/or, after the mobile phone 100 reduces the frame rate to frame rate 2, if the single front mode or the single rear mode is used again thereafter, the frame rate can be restored to frame rate 1. That is to say, the mobile phone 100 will record the resolution set by the user in the single front mode or the single rear mode, and when the single front mode or the single rear mode is used again, the resolution set last time can be used. Similarly, the mobile phone 100 will record the frame rate set by the user in the single front mode or the single rear mode, and when the single front mode or the single rear mode is used again, the frame rate set last time can be used. That is to say, after displaying the second interface, the mobile phone 100 may receive an operation (also referred to as a second operation) that triggers the mobile phone 100 to switch to the single front mode or the single rear mode. In response to this operation, the mobile phone 100 can display the fourth interface. The fourth interface is a viewfinder interface for video recording in a single front mode or a single rear mode, and the fourth interface includes a preview image ( may also be referred to as a sixth preview image).

It should be noted that the resolution and frame rate supported by the single front mode are the same as those supported by the single rear mode. Therefore, in the resolution and frame rate adjustment scheme, the single Front mode and single rear mode. For example, resolution 1 is initially set in single front mode, and then automatically reduced to resolution 2 due to switching, and can be restored to resolution 1 by switching to single front mode or single rear mode again.

The specific implementation of the aforementioned automatic adjustment of resolution and frame rate is illustrated by taking the switching process before recording as an example. In actual implementation, when switching between multi-mirror modes during the recording process, the above-mentioned method can also be used. For specific implementation, please refer to the relevant description before recording, and will not repeat them here. The only thing to note is that the resolution and frame rate can only be set by the user before recording, so in recording, the resolution 1 and/or frame rate 1 used before switching is set before starting recording, rather than set in the recording.

However, in video recording, if the above-mentioned automatic resolution and frame rate adjustment method is adopted, different resolutions or frame rates before and after switching will be finally reflected in the formed video file, which may affect the quality of the video.

Exemplarily, as shown in Figure 8D, in the video recording, within 5 seconds from 00:00:00 to 00:04:59, the mobile phone 100 uses a single rear mode and uses a frame rate of 60 frames (fps) to record video. In the 5th second, the mobile phone 100 switches to the front and rear dual-lens mode, and automatically reduces the frame rate to 30 frames (fps), and then records a video at 30 fps within 10 seconds from 00:05:00 to 00:14:59. Correspondingly, after the video file is finally formed, if the video file is played on a device with a higher configuration, since the frame rate in the first 5 seconds is twice the frame rate in the last 10 seconds, external factors such as network quality will not be considered. Under the premise, the fluency of the first 5 seconds of video will be higher than that of the last 10 seconds of video. This leads to inconsistencies in the perception of the video.

Based on this, in the embodiment of the present application, a video shooting method is also provided, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can control the switching of the multi-mirror mode according to acquisition parameters (such as frame rate and/or resolution). Wherein, in the process of video recording, in the case of video recording in single front mode or single rear mode, if the acquisition parameter (also referred to as the first acquisition parameter) at this time is less than or equal to the preset parameter threshold, the mobile phone 100 allows switching to use two cameras to capture images. If the acquisition parameter at this time is greater than the preset parameter threshold, the mobile phone 100 is prohibited from switching to use the two cameras to acquire images. In this way, while controlling the size of the video file, the video effect can be improved, and the inconsistency between the two videos before and after can be avoided.

In some embodiments, when the mobile phone 100 is in the single front mode or the single rear mode, and adopts a resolution of 3 and/or a frame rate of 3 to start recording video, the mobile phone 100 can be in the viewfinder interface of the single front mode or The viewfinder interface of the single rear mode displays operable mode icons and display controls on the display panel. Wherein, the resolution 3 is less than or equal to the preset resolution threshold, and the frame rate 3 is less than or equal to the preset frame rate threshold.

Exemplarily, taking the preset resolution threshold as 1080p and the preset frame rate threshold as 30 frames as an example, the mobile phone 100 uses a single rear mode, and adopts 720p (less than the preset resolution threshold) and 30 frames (equal to the preset In the case of starting to record a video, the mobile phone 100 may display the viewfinder interface 831 shown in (a) of FIG. 8E . The viewfinder interface 831 includes a mode icon 832, which is normally displayed, that is, the mode icon 832 is operable. Moreover, the viewfinder interface 831 includes a panel display control 833 . It should be understood that the text "720p, 30 frames of video recording" in the viewfinder interface 831 is only illustrative, and it is usually not displayed during the actual video recording process.

Then, the mobile phone 100 can display a selection panel in response to the user's click operation on the operable mode icon or panel display control, which includes multiple mode options for the user to choose from and trigger the mobile phone 100 to switch to the multi-mirror mode. Moreover, after the multi-mirror mode is switched, the mobile phone 100 can still use resolution 3 and/or frame rate 3 to record video. That is to say, when the mobile phone 100 is in the single front mode or the single rear mode, and adopts the resolution 3 and/or frame rate 3 to start recording video, the mobile phone 100 can allow the user to switch the multi-mirror mode, and before and after the switch can be Record video at the same resolution and frame rate. In this way, the resolution and frame rate of the recorded video can be guaranteed to be consistent.

Continuing the example of (a) in FIG. 8E , after switching to the front and rear dual-lens mode, as shown in the text in the viewfinder interface 834 shown in (b) in FIG. 8E , the mobile phone 100 can still use 720p, 30 frame to record video. Similarly, the words "use 720p, 30-frame video recording" in the viewfinder interface 834 are only illustrative.

In other embodiments, when the mobile phone 100 starts to record video in the single front mode or the single rear mode, and adopts resolution 1 and/or frame rate 1, the mobile phone 100 can display the viewfinder interface in the single front mode Or an inoperable (eg, grayed out) mode icon is displayed on the viewfinder interface of the single rear mode, and the viewfinder interface of the single front mode or the viewfinder interface of the single rear mode does not include a panel display control. That is to say, when the mobile phone 100 starts to record video in single front mode or single rear mode, and adopts high resolution and/or high frame rate, the mobile phone 100 prohibits the user from switching to the front and rear dual mirror mode, rear dual mirror mode, and rear dual mirror mode. mirror mode and picture-in-picture mode. In this way, it can be guaranteed that the recorded video will not have inconsistent resolution or frame rate.

Exemplarily, taking the preset resolution threshold as 1080p and the preset frame rate threshold as 30 frames as an example, the mobile phone 100 uses a single rear mode, and adopts 4K (greater than the preset resolution threshold) and 60 frames (greater than the preset In the case of starting to record a video, the mobile phone 100 may display the viewfinder interface 841 shown in (a) in FIG. 8F . The viewfinder interface 841 includes a mode icon 842, which is grayed out, that is, the mode icon 842 is inoperable. Moreover, the viewfinder interface 841 does not include a panel display control. If the mode icon 842 is inoperable and does not include panel display controls, the user cannot trigger the mobile phone 100 to switch to the multi-mirror mode. It should be understood that the text "use 4K, 60 frames of video recording" in the viewfinder interface 841 is only illustrative, and it is usually not displayed during the actual video recording process.

It should be noted that when the mobile phone 100 is in single front mode or single rear mode, and starts to record video with resolution 1 and/or frame rate 1, the front and rear camera switching controls can still be displayed on the viewfinder interface. For example, the front and rear camera switching control is the control 843 in the viewfinder interface 831 shown in (a) of Figure 8F. That is to say, the mobile phone 100 can still switch between the single front mode and the single rear mode in response to the user's operation on the front and rear camera switching controls. In this case, there is no need to adjust the resolution and frame rate, so that it can be ensured that the recorded video will not have inconsistent resolution or frame rate.

That is to say, in this embodiment, before video recording starts, the mobile phone 100 may display the first interface. The first interface is a viewfinder interface before recording in a single front mode or a single rear mode. rate 1, frame rate 3 and/or resolution 3) the preview image (also referred to as the first preview image) collected. And, the first preview image is displayed in full screen on the first interface. Then, the mobile phone 100 may receive an operation (also referred to as a first operation) that triggers the mobile phone 100 to start video recording.

In one case, the mobile phone 100 responds to the operation of triggering the mobile phone 100 to start recording, if the first collection parameter is less than or equal to the preset parameter threshold, such as the frame rate 3 is less than or equal to the preset frame rate threshold, and the resolution 3 is less than or equal to In the case of a preset resolution threshold, the mobile phone 100 may display the second interface. The second interface is the viewfinder interface where the mobile phone 100 is recording. The second interface includes a preview image (also called a second preview image) collected by a single camera (such as the first camera) with the first acquisition parameters and an operable image. A first control (such as a modal icon and/or a panel presentation control).

It should be understood that, if the first control is in an operable state, the first control can be used to switch between the two cameras to capture images. That is, the first collection parameter is less than or equal to the preset parameter threshold, and the mobile phone 100 allows switching to use two cameras to collect images.

Specifically, after the second interface is displayed, the mobile phone 100 may receive a user's operation (also referred to as a second operation) on the first control in an operable state, so as to trigger the mobile phone 100 to switch the shooting mode. In response to this operation, the mobile phone 100 may display multiple mode options on the second interface for the user to select a shooting mode. The multiple mode options include a first option, and the first option corresponds to a mode in which two cameras are used to capture images (such as front and rear dual-mirror mode, rear-rear dual-mirror mode, or picture-in-picture mode). The mobile phone 100 may receive the user's selection operation of the first option. The mobile phone 100 may display the fourth interface in response to the selection operation. The fourth interface is the viewfinder interface where the mobile phone 100 is recording video, and the fourth interface includes two cameras (also referred to as the second camera and the second camera) respectively with the first acquisition parameters (such as resolution 3, frame rate 3) Captured preview image. For example, the third preview image collected by the second camera with the first collection parameters, and the fourth preview image collected by the third camera with the first collection parameters.

In another case, the mobile phone 100 responds to the operation of triggering the mobile phone 100 to start recording, if the first collection parameter is greater than the preset parameter threshold, such as the frame rate 1 is greater than the preset frame rate threshold, and/or the resolution 1 is greater than the preset In the case of the resolution threshold, the mobile phone 100 may display a third interface. The third interface is a viewfinder interface where the mobile phone 100 is recording. The third interface also includes a preview image (such as a second preview image) collected by a single camera (such as the first camera) with the first acquisition parameters. However, the third interface does not include the first controls (such as mode icons and/or panel display controls) in an operable state. There are two possibilities for not including the first control in the operable state: first, including the inoperable first control, for example, including the inoperable mode icon. The second type does not include the first control, for example, does not include a panel display control. It should be understood that in actual implementation, the third interface may include inoperable mode icons and does not include panel display controls.

It should be understood that if the third interface does not include the first control in an operable state, then the first control cannot be used to switch and use the two cameras to capture images. That is, if the first collection parameter is greater than the preset parameter threshold, the mobile phone 100 is prohibited from switching to use two cameras to collect images.

Specifically, take the third interface including the first control in an inoperable state as an example. After the mobile phone 100 displays the third interface, if the user's second operation on the first control is received, the mobile phone 100 will not display multiple mode options, but will display prompt 2 (also called the first prompt message) , the prompt 2 is used to prompt that two cameras cannot be switched to collect images.

Exemplarily, continuing the aforementioned example of (a) in FIG. 8F , the mobile phone 100 responds to the user's click operation on the mode icon 842 in the viewfinder interface 841 shown in (a) in FIG. A prompt 844 as shown in (b) in FIG. 8F is displayed, and the prompt 844 is specifically "Multi-camera video can be used in 720p or 1080p, 30 frames". In this way, it can be prompted that the multi-mirror mode cannot be switched under the conditions of 4K and 60 frames. That is, prompt 844 is prompt 2.

Embodiment five, double speed function.

The embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can implement a double speed function, which refers to the function of the mobile phone 100 playing recorded video frames at double speed. As shown in Figure 9A, the video shooting method of this embodiment may include:

S901. The mobile phone 100 displays a first interface; wherein, the first interface is a viewfinder interface where the mobile phone 100 is recording video, and the first interface includes a first logo and a first preview image collected by the camera, and the first logo is used to indicate that the mobile phone 100 will play the recorded video at the first speed which is greater than 0.

In the embodiment of the present application, the recording is being recorded, and the identification (such as the first identification and the second identification) is the double speed identification.

Exemplarily, the first interface is the viewing interface 201d shown in (a) of FIG. 2D . The viewfinder interface 201d is a viewfinder interface where the mobile phone 100 is recording in front and rear dual-lens mode. The first preview image includes a preview image 202d collected by a rear camera (such as a rear main camera) and a preview image 203d collected by a front camera. The first logo is the logo 226 (i.e. double speed logo) in the viewfinder interface 201d shown in (a) in FIG. It is 1x speed.

Also exemplary, the first interface is the viewfinder interface 203e shown in (b) of FIG. 2E. The viewfinder interface 203e is a viewfinder interface where the mobile phone 100 is recording in single rear mode. The first preview image is a preview image 204e captured by a rear camera (such as a rear main camera). The first logo is the logo 250 (i.e. the double speed logo) in the viewfinder interface 203e shown in (b) of FIG. It is 1x speed.

That is to say, in different multi-mirror modes, the number of cameras collecting preview images may be different, so the number of preview images collected at the same time is also different. That is, the first preview image may be a preview image collected by one camera, or may be a preview image collected by two or more cameras. In the following description about the double-speed function, the case of two cameras (such as the front and rear dual-lens mode) will be used for illustration. Correspondingly, the first preview image is the preview image captured by the two cameras.

By default, the playback speed is 1x speed. For example, in the above examples of (a) in FIG. 2D and (b) in FIG. 2E , the first mark indicates that the recorded video is played at 1x speed. It should be noted that after adjusting the playback speed once, the playback speed may change. That is, the first speed may also be other playback speeds, such as 2x speed, 4x speed and so on.

S902. The mobile phone 100 receives the user's first operation on the first interface. Wherein, the first operation is used to trigger the mobile phone 100 to adjust the mobile phone 100 to play the recorded video at a second speed, the second speed is greater than 0, and the second speed is different from the first speed.

It should be understood that the speeds (such as the first speed, the second speed, etc.) herein are all values greater than 0.

In the embodiment of the present application, the adjacent playback speeds before and after the adjustment are different. For example, the second speed is different from the first speed. Similarly, when the second speed is greater than 1x speed, it is an accelerated playback speed; when the second speed is greater than 0 and less than 1x speed, it is a slowed down playback speed; when the second speed is equal to 1x speed, it is a normal playback speed .

In some embodiments, the first operation may be a first preset gesture, or a long press operation on an area of the first interface where no controls or icons are displayed.

In some other embodiments, the first interface includes a speed adjustment control, and the first operation may be an operation (such as a click operation, a slide operation) that triggers the speed adjustment control.

In some other embodiments, the first interface may include a first preset control (such as a logo), and the first preset control is used to trigger the mobile phone 100 to display multiple speed options, and each speed option corresponds to a playback speed of a video . The mobile phone 100 may receive a user's click operation on the first preset control. The mobile phone 100 can only display multiple speed options in response to the user's click operation on the first preset control. In this way, only when there is a need to adjust the speed, the display of multiple speed options may be triggered for the user to select the adjusted speed. Therefore, the content of the elements displayed on the first interface can be reduced without the need to adjust the speed, and at the same time, the user can be guided to select the speed in a targeted manner.

In this embodiment, the first operation is a selection operation for the user to select a speed option corresponding to the second speed from a plurality of speed options. Specifically, before S902, the method further includes: the mobile phone 100 receiving a user's click operation on the first preset control in the first interface. The mobile phone 100 displays multiple speed options on the first interface in response to the user's click operation on the first preset control.

Exemplarily, the first interface is the viewfinder interface 201d shown in (a) of FIG. 2D , and the first preset control is the double-speed sign in the viewfinder interface 201d, that is, the sign 226 . That is to say, the double-speed logo is not only the first logo, but also the first preset control. The mobile phone 100 may receive the user's click operation on the logo 226 in the viewfinder interface 201d shown in (a) of FIG. 2D . The mobile phone 100 displays the first interface 911 shown in (a) in FIG. 9B in response to the user's click operation on the logo 226 . The first interface 911 includes a plurality of speed options as follows: a speed option 912 , a speed option 913 and a speed option 914 . Wherein, the playback speed corresponding to the speed option 912 is 1x speed, the playback speed corresponding to the speed option 913 is 2x speed, and the playback speed corresponding to the speed option 914 is 4x speed. It should be noted that when multiple speed options are displayed, the function icons around the multiple speed options are hidden. For example, hide the flash light icon. In this way, the interface elements can be simplified to facilitate the user to select the playback speed.

In S902, the mobile phone 100 receives the user's first operation on the first interface, including: the mobile phone 100 receives the user's selection operation on the first speed option among the multiple speed options, and the corresponding playback speed of the first speed option is the second speed. The second speed is different from the first speed.

Wherein, the selection operation may be a click operation, a long press operation, and the like.

Exemplarily, the first speed option is the speed option 914 shown in (a) of FIG. 9B . The mobile phone 100 can receive the user's click operation on the speed option 914 among the multiple speed options (such as the speed option 912, the speed option 913 and the speed option 914) shown in (a) in Figure 9B, and the playback speed option 913 corresponds to The speed is 4x speed, that is, the second speed is equal to 4x speed.

In the following embodiments, the method in the embodiments of the present application will be introduced mainly by taking as an example that the first operation is a selection operation in which the user selects a speed option corresponding to the second speed from multiple speed options.

S903. The mobile phone 100 displays a second interface in response to the first operation. The second interface is a viewfinder interface where the mobile phone 100 is recording video. The second interface includes a second logo and a second preview image collected by the camera. The second interface The identifier is used to indicate that the mobile phone 100 will play the recorded video at the second speed.

Exemplarily, the first speed option is the speed option 914 shown in (a) of FIG. 9B . In response to the user's click operation on the speed option 914 in (a) in FIG. 9B , the mobile phone 100 can display the viewfinder interface 915 shown in (b) of FIG. Second interface. The viewfinder interface 915 is the viewfinder interface where the mobile phone 100 is recording, and the viewfinder interface 915 includes a second mark 916, which is used to indicate that the mobile phone 100 will play the recorded video at 4 speeds, that is, the second speed is equal to 4 times speed. The second preview image includes a preview image 917 collected by a rear camera (such as a rear main camera) and a preview image 918 collected by a front camera.

So far, it should be noted that there is no essential difference between the second interface and the aforementioned first interface, and both are viewfinder interfaces where the mobile phone 100 is recording video. The difference is that the playback speed indicated by the second logo displayed on the second interface is the second speed, while the playback speed indicated by the first logo displayed on the first interface is the first speed. That is to say, the first interface is a viewfinder interface corresponding to when the playback speed is the first speed. The second interface is a viewfinder interface corresponding to when the playback speed is the second speed.

It should be noted that both the second preview image and the first preview image above are preview images collected by the camera in real time. Specifically, the second preview image is a preview image collected by the camera in real time when the playback speed is the second speed, and the first preview image is a preview image collected by the camera in real time when the playback speed is the first speed.

In some embodiments, in order to restore to the default playback speed (such as 1x speed) conveniently, when the playback speed indicated by the speed identifier (such as the first identifier and the second identifier) is not equal to the default playback speed, the mobile phone 100 is The video viewfinder interface (such as the first interface and the second interface) also includes a second preset control. The second preset control is used to trigger the mobile phone 100 to play the recorded video at the default playback speed. That is to say, the user's operation of the second preset control can trigger the mobile phone 100 to restore the playback speed to the default playback speed. In this way, the convenience of returning to the default playback speed can be improved.

Exemplarily, taking the default playback speed of 1X as an example, the viewfinder interface 915 shown in (b) of FIG. 9B includes a second logo 916, which indicates that the mobile phone 100 will play the recorded video at 4X speed. , it is obvious that the playback speed is 4x speed, not 1x speed. At this time, the mobile phone 100 may display a second preset control 919 in the viewfinder interface 915 . In response to the user's click operation on the second preset control 919, the mobile phone 100 can be adjusted to play the recorded video at 1x speed.

What needs to be explained here is that the playback speed refers to the speed at which the recorded video is played after the video recording is completed and the user triggers the video playback, not the preview speed in the viewfinder interface. That is to say, in the viewfinder interface, the first preview image or the second preview image is previewed at a normal 1x speed.

When the playback speed is adjusted to a non-default playback speed, the user mainly needs to record a video played at double speed. In this case, there is usually no need to switch the multi-mirror mode. Based on this, in some other embodiments, in order to avoid user misoperation, when the playback speed indicated by the double-speed logo (such as the first logo and the second logo) is not equal to the default playback speed, the mobile phone 100 will hide the video being recorded. Mode icons, panel display controls, and front and rear camera switching controls in the viewfinder interface (such as the first interface and the second interface), so that switching of the multi-mirror mode can be prohibited at non-default playback speeds. Exemplarily, taking the default playback speed of 1X as an example, the viewfinder interface 915 shown in (b) of FIG. 9B includes a second logo 916, which indicates that the mobile phone 100 will play the recorded video at 4X speed. , it is obvious that the playback speed is 4x speed, not 1x speed. At this time, the viewfinder interface 915 does not include mode icons, panel display controls, and front and rear camera switching controls.

S904. The mobile phone 100 receives a second operation of the user on the second interface, where the second operation is used to trigger the mobile phone 100 to end video recording.

In this embodiment of the present application, a specific form of the second operation is not limited. Exemplarily, the second interface includes an end recording control, and the second operation may be a trigger operation (such as a click operation, a long press operation) on the end recording control.

In addition, in some embodiments, when the playback speed indicated by the second logo is not equal to the second preset speed (that is, the second speed is not equal to the second preset speed), the second interface further includes a third preset control . The third control is used to trigger the mobile phone 100 to end the recording. The mobile phone 100 may end the video recording in response to the user's click operation on the third preset control. That is to say, through the third control, the recording can be ended directly at a speed other than the second preset speed. Alternatively, the second operation may also be a second preset gesture. For example, the second operation is an upward swipe gesture for the user to swipe upward from the bottom of the second interface.

S905. The mobile phone 100 generates a first video file in response to the second operation, the first video file includes a first video stream and a second video stream, the first video stream includes multiple frames of the first preview image, and the second The video stream includes multiple frames of the second preview image.

After the recording is finished, the mobile phone 100 generates the first video file. The first video file is a video file to be played. For example, after the user clicks to end the recording, the mobile phone 100 generates a first video file and stores it in the photo album application. Then, the user can enter the photo album application to trigger playing the first video file.

Exemplarily, taking the front and rear dual-lens mode as an example, the cameras that capture preview images at the same time include a rear camera and a front camera. As shown in FIG. 9C , within the first 10 seconds from 00:00:00 (starting at the 0th second) to 00:09:59 (ending at the 9th second), the playback speed is the first speed. At 00:09:59 (or 00:10:00), the mobile phone 100 adjusts the playback speed to the second speed in response to the user's first operation. Then, within 5 seconds from 00:10:00 (start of the 10th second) to 00:14:59 (end of the 14th second), the playback speed is the second speed. At 00:14:59, the mobile phone 100 generates a first video file in response to the user's second operation, the first video file 1001 includes a video stream a1 and a video stream a2, and the video stream a1 includes the rear camera at 00:00: The multi-frame preview image 921 collected and displayed on the first interface between 00-00:09:59, the video stream a2 including the front camera is collected and displayed on the first interface between 00:00:00-00:09:59 A multi-frame preview image 922 of the interface. That is, the first video stream is composed of video stream a1 and video stream a2. The first video file also includes a video stream b1 and a video stream b2, the video stream b1 includes a multi-frame preview image 923 collected by the rear camera between 00:10:00-00:14:59 and displayed on the first interface, The video stream b2 includes a multi-frame preview image 924 collected by the front camera between 00:10:00-00:14:59 and displayed on the first interface. That is, the second video stream is composed of video stream b1 and video stream b2.

In some embodiments, in order to realize double-speed playback, the video stream may be obtained through frame extraction or frame insertion, and then a video file may be generated. In this way, there is no need for any processing during playback, and double-speed playback can be achieved by direct playback. Specifically, when the first speed is not equal to the default playback speed (such as 1x speed), the first video stream includes multiple frames of the first preview image, and the multiple frames of the first preview image are all the first preview images collected by the camera. The image is obtained after frame extraction processing or frame interpolation processing. In the case that the second speed is not equal to the first preset speed (such as 1x speed), the second video stream includes multiple frames of second preview images, and the multiple frames of second preview images are all second preview images collected by the camera. Obtained after frame extraction or frame interpolation. Wherein, for the accelerated playback speed (such as 2x speed), it is obtained by frame extraction. For example, a number of preview images are selected for each first preset frame, wherein the number of first preset frames may be the same as the value of the playback speed, and the number of frames may be equal to the value of the playback speed minus 1. For the slowed down playback speed (such as 0.5 times speed), it is obtained through frame interpolation processing. For example, a repeated preview image, a solid color image, or a blank frame image, etc., are inserted after each frame with the number of frames minus 1 from the reciprocal of the playback double speed. For the specific implementation of frame extraction processing and frame insertion processing, reference may be made to the prior art in this field, which will not be repeated here.

In some other embodiments, the mobile phone 100 does not perform frame extraction or frame insertion processing on the preview image during the process of obtaining the video stream (such as the first video stream or the second video stream). Correspondingly, the first video stream includes all first preview images, and the second video stream includes all second preview images. In addition, the first speed attribute is marked as the first speed for the first video stream, and the first speed attribute is marked as the second speed for the second video stream, so that during subsequent playback, double-speed playback can be realized according to the speed attribute.

S906. The mobile phone 100 receives a third operation of the user, and the third operation is used to trigger the mobile phone 100 to play the first video file.

Exemplarily, the third operation is the user's click operation on the play button of the first video file in the photo album (or gallery) application. Alternatively, the third operation is the user's selection operation of the opening mode of the first video file in the file management application. For example, in the file management application of the mobile phone 100, the mobile phone 100 can display multiple options for opening the file (such as video application a, video application b, video application c) in response to the user triggering the operation of displaying the opening mode of the first video file. ). The third operation may be a user's click operation on any one of the opening methods.

S907. In response to the third operation, the mobile phone 100 plays the first video stream at a first speed, and plays the second video stream at a second speed.

During the process of playing the first video file, the mobile phone 100 plays the videos recorded before and after adjustment at different playback speeds. In this way, different segments of the video can be played at different speeds based on the user's first operation during the video recording process.

Wherein, when the first speed is lower than the default playback speed, the playing time for playing the first video stream is longer than the collection time for the camera to collect all the first preview images. Ideally, the playback duration is m times the acquisition duration. In the case that the first speed is equal to the default playback speed, the playback duration of playing the first video stream is equal to the acquisition duration of all first preview images collected by the camera. In the case that the first speed is greater than the default playback speed, the playback duration of playing the first video stream is shorter than the acquisition duration of capturing all the first preview images by the camera. Ideally, the acquisition time is m times the playback time.

For example, take the first preset speed equal to 1x speed as an example. In FIG. 9C , the playback speed is switched in the 10th second, and the camera is collecting the first preview image in the first 10 seconds. Assuming that the first speed is equal to 1, the result of playing the first video stream at the first speed should be: the playing duration of the first video stream is equal to 10 seconds. Assuming that the first speed is equal to 2, the result of playing the first video stream at the first speed should be: the playing duration of the first video stream is equal to 5 seconds. Assuming that the first speed is equal to 0.5, the result of playing the first video stream at the first speed should be: the playing duration of the first video stream is equal to 20 seconds.

Similarly, the same is true for the second speed, which will not be repeated here.

In some embodiments, corresponding to the method of obtaining the first video stream and the second video stream through frame insertion processing or frame extraction processing, the first video stream can be played at the first speed by playing the first video stream normally. Playing the second video stream normally can realize playing the second video stream at the second speed. In this way, the first video stream and the second video stream are obtained by performing frame insertion processing or frame extraction processing in advance, so that double-speed playback can be realized without video processing during video playback. Thereby, the fluency of double-speed playback can be improved.

In some other embodiments, corresponding to constructing all the first preview images to obtain the first video stream, constructing all the second preview images to obtain the second video stream, and adding a speed attribute, during the playback process according to the speed attribute Achieve double-speed playback.

In a specific implementation manner, frame skipping playback or frame insertion playback may be performed according to the speed attribute, thereby realizing double-speed playback.

Exemplarily, taking frame interpolation playback as an example, if the first speed indicated by the first speed attribute satisfies that the first speed is greater than 1, then realizing double-speed playback according to the speed attribute may be: only one frame is played in every m frames of the first preview image The first preview image (i.e. skip mode); if the first speed indicated by the first speed attribute satisfies that the first speed is greater than 0 and less than 1, then the double-speed playback can be realized according to the speed attribute: before every frame of the first preview image or Afterwards, 1/m-1 frames of blank images (such as pure black images) or 1/m-1 frames of repeated first preview images are inserted (ie, interrupted playback). Wherein, m is the first speed.

In another specific implementation manner, time-lapse or delayed playback may be performed according to the speed attribute, thereby realizing double-speed playback.

Exemplarily, if the first speed indicated by the first speed attribute satisfies that the first speed is greater than 1, then realizing double-speed playback according to the speed attribute may be to reduce the playback duration of each frame of the first preview image, so that the reduced playback duration is normal 1/m times of the playback duration (i.e. time-lapse playback); if the first speed indicated by the first speed attribute satisfies that the first speed is greater than 0 and less than 1, then realizing double-speed playback according to the speed attribute can be to prolong the first preview image of each frame The playback duration of the extended playback is m times the normal playback duration (i.e. delayed playback). Wherein, m is the first speed.

It can be seen that, in this embodiment, double-speed playback can be realized in real time during the playback process, and all originally collected image frames can be retained.

To sum up, using the video processing method provided by the embodiment of the present application, during the video recording process, the mobile phone 100 can adjust the playback speed from the first speed to the second speed in response to the user's first operation on the first interface. speed. That is to say, in the recording, the playback speed can be adjusted, providing a new way to adjust the playback speed. Thereby, the flexibility of playing speed adjustment is improved.

In addition, the mobile phone 100 forms the first video stream with the first preview image collected before the playback speed is adjusted, and forms the second video stream with the second preview image collected after the playback speed is adjusted. Then, when playing the video, the first video stream is played at the first speed, and the second video stream is played at the second speed. In this way, after the recording is completed, different video streams can be played at different speeds without the user performing any operation, so that the playback speed is consistent with the timing when the user performs the first operation during the recording process. Thereby, the intelligence of double-speed playback can be improved.

It should be noted that in the embodiment shown in FIG. 9A , only one process of adjusting the playback speed is used to illustrate the specific implementation of double-speed playback. In practice, during a video recording process, the playback speed may be adjusted twice or more, and each adjustment process can refer to S901-S903. Moreover, every time an adjustment is added, there will be an additional segment of video stream in the generated first video file. For the specific implementation process, refer to the embodiment in FIG. 9A , which will not be repeated here.

In addition, in the above-mentioned embodiment shown in FIG. 9A , the specific implementation of double-speed playback is mainly described in the multi-mirror mode using two cameras. In practice, in the scenario where a single camera is used, the realization principle of double-speed playback is the same, except that both the first video stream and the second video stream only include video streams composed of preview images captured by one camera.

Embodiment 6, micro-movie function.

The embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can implement a micro-movie function, and the micro-movie function refers to the function that the mobile phone 100 can record a micro-movie composed of various motion effects. As shown in Figure 10A, the video shooting method of this embodiment may include:

S1001. The mobile phone 100 displays interface a, where the interface a is a viewfinder interface before the mobile phone 100 starts video recording, and the interface a includes real-time images collected by cameras a and b.

S1002. The mobile phone 100 displays multiple template options on the interface a in response to the user's operation a on the interface a. The operation a is used to trigger the mobile phone 100 to record a micro movie, and each template option corresponds to a motion template for image processing. The dynamic effect template is used to process preview images collected by at least two cameras among the plurality of cameras and obtain corresponding animation effects.

Wherein, the operation a may be a preset gesture a (such as a sliding gesture, a long press gesture) performed by the user in the interface a. Alternatively, the interface a includes a microfilm control, and the microfilm control is used to trigger the mobile phone 100 to display multiple template options. Operation a is an operation such as clicking or long-pressing the micro-movie control by the user. In the following embodiments, the solution of this application will be described mainly by taking operation a as a user's click operation on the microfilm control.

Exemplary, the microfilm control is the control 214 in the viewfinder interface 203a shown in (b) in FIG. Click Actions.

In S502, in response to the user's click operation on the control 214 in the viewfinder interface 203a shown in (b) in FIG. 2A, the mobile phone 100 may further display the Template option 1011 , template option 1012 , template option 1013 and template option 1014 . Among them, template option 1011 corresponds to the dynamic effect template of "Friends Gathering", template option 1012 corresponds to the dynamic effect template of "Warm Moment", template option 1013 corresponds to the dynamic effect template of "Intimate Time", and template option 1014 corresponds to the dynamic effect template of "Pleasant Moment". Motion template.

Wherein, the dynamic effect template is a template for simulating the dynamic effect of the video captured by the camera in various motion states. Wherein, the motion state includes states such as pushing, pulling, shaking, moving, heeling and/or throwing. Each dynamic effect template includes at least one dynamic effect in a motion state.

It should be noted that in multi-mirror modes that use two cameras, such as front and rear dual-mirror mode, rear-rear dual-mirror mode, and picture-in-picture mode, multiple template options are usually applicable to the animation templates of the multi-mirror mode of two cameras. Template options. In a single-camera multi-mirror mode such as a single-front mode or a single-rear mode, multiple mode options are usually template options for motion templates in the multi-mirror mode of a single camera. That is to say, the multiple template options displayed by the mobile phone in response to the user's click operation on the microfilm control are the template options of the available dynamic templates in the current multi-mirror mode.

In some other embodiments, the mobile phone 100 displays multiple template options in the interface a in response to the operation a. At the same time, multiple function icons and controls in interface a will be hidden to simplify the elements in the interface and facilitate the selection of template options. For example, compared to (b) in FIG. 2A : in (a) in FIG. 10B , the beautification control, front and rear camera switch control, and camera submenu are hidden.

S1003. The mobile phone 100 displays an interface b in response to the user's operation b on the template option c among the multiple template options. The operation b is used to trigger the mobile phone 100 to play animation effects. Interface b is used to play the animation effect of animation template a corresponding to template option c.

In some embodiments, operation b may be a user's selection operation on template option c (such as a click operation, a long press operation, etc.). For example, template option c is the template option 1011 shown in (a) in FIG. 10B , and operation b may be a user's click operation on the template option 1011 shown in (a) in FIG. 10B .

In some other embodiments, the user's selection operation on the template option c can only trigger the mobile phone 100 to select the dynamic effect template a. Then, the mobile phone 100 can only display the interface b in response to the user's preset operation a on the interface a. For example, the preset operation a may be a preset gesture b (such as a sliding gesture) on the interface a. Alternatively, the preset operation a is a long press operation on an area in the interface a where no controls or icons are displayed. Alternatively, the interface a includes a control d, which is used to trigger the mobile phone 100 to play an animation effect, and the preset operation a is a user's trigger operation on the control d (such as a click operation, a long press operation, etc.).

Exemplarily, taking template option c as template option 1011 and control d as control 1015 as an example, operation b includes the user selecting the template option 1011 and clicking the control 1015 .

In S1003, the mobile phone 100 may display the interface 1015 shown in (b) in FIG. 10B in response to the user's operation b on the template option c. The interface 1015 includes a window 1017 . The window 1017 is used to play the dynamic template a. That is, interface 1015 is interface b.

It should be understood that the interface b shown in (b) in FIG. 10B is only exemplary. The interface b is to add a mask layer (such as a gray mask layer) on top of the real-time preview image in the interface a, display multiple template options, control d and other interface elements on the mask layer, and display window a on the mask layer And get. However, actual implementation is not limited to this.

In some embodiments, the interface b also includes a plurality of template options, so that the user can reselect the dynamic effect template a in the interface b. In this way, there is no need to return to interface a, and the dynamic effect template can be continuously switched in interface b.

S1004. In response to the user's operation c on the interface b, the mobile phone 100 uses the dynamic effect template a to process the real-time image a collected by the camera c and the real-time image b collected by the camera d to record a micro movie. Wherein, the camera c is a camera among the plurality of cameras, and the camera d is a camera except the camera c among the plurality of cameras.

Wherein, the operation c may be a preset gesture c of the user in the interface b. For example, the preset gesture c is a sliding gesture from right to left in the interface b. Alternatively, the interface b includes a control e, and the control e is used to trigger the mobile phone 100 to start micro-movie recording. Operation c may be a trigger operation (such as a click operation, a long press operation, etc.) on the control e. For example, the control e is the control 1018 shown in (b) in FIG. 10B , and the operation c is the user's click operation on the control 1018 .

In response to the user's operation c on the interface b, the mobile phone 100 can use the motion effect template a to perform motion effect processing to complete the recording of the micro movie. For example, dynamic effect processing is performed on the real-time image a collected by the camera c and the real-time image b collected by the camera d, so as to achieve the animation effect of the dynamic template a.

In some embodiments, different motion effect templates are suitable for performing motion effect processing on preview images captured by different cameras. In short, different animation templates are suitable for different cameras. Camera c and camera d are two cameras applicable to animation template a.

In summary, using the video shooting method provided by the embodiment of the present application, in the scene of dual-lens video recording, according to the motion template selected by the user, the real-time images collected by the two cameras can be dynamically processed to obtain a dynamic effect. Animated microfilm. In this way, micro-movie recording in a dual-lens recording scene can be realized, so that rich dual-lens video content can be recorded. Moreover, there is no need for the user to control complex operations such as framing, which can reduce the difficulty of recording micro movies.

Furthermore, usually, a micro movie includes multiple movie clips. Correspondingly, the dynamic effect template a includes a plurality of dynamic effect sub-templates, and a plurality of movie clips corresponds to a plurality of dynamic effect sub-templates one by one. Each animation sub-template is used for animation processing of the real-time images collected in the corresponding movie segment. Thus, micro-movies with richer animation effects can be processed.

In some embodiments, in order to specifically perform animation processing on real-time images captured by different cameras, each animation sub-template further includes sub-template a and sub-template b. The sub-template a is used for the mobile phone 100 to perform dynamic effect processing on the real-time image a, and the sub-template b is used for the mobile phone 100 to perform dynamic effect processing on the real-time image b. In this way, corresponding sub-templates can be used for processing for different cameras. Therefore, different animation effects can be obtained by processing the preview image at the same time, which can further improve the processing effect.

On this premise, as shown in Figure 10C, S1004 of the foregoing embodiment further includes S1021-S1022, and after S1004, S1023 is also included:

S1021. The mobile phone 100 displays an interface c in response to the event a. The interface c is the viewfinder interface before starting the dual-camera video recording. The interface c includes the real-time image c collected by the camera c and the real-time image d collected by the camera d. The interface c also includes fragment options for multiple movie fragments.

It should be noted that there is no essential difference between the real-time image c and the real-time image a, both of which are real-time images collected by the camera c, but real-time images collected by the camera at different time periods. The real-time image a is a real-time image collected during the recording process of the movie segment, and the real-time image c is a real-time image collected during the recording preparation process of the movie segment (that is, when the interface c is displayed). Similarly, there is no essential difference between the real-time image d and the real-time image b, and the reason is the same as above.

Wherein, the interface c is the viewfinder interface before starting the dual-camera video recording. That is to say, when the interface c is displayed, the recording does not actually start. Therefore, in the process of displaying the interface c, the mobile phone 100 can adjust the viewing angle according to the user's movement of the mobile phone 100 . And the framing changes during the adjustment process will not be recorded in the video. In this embodiment, the process of adjusting the framing is called recording preparation.

Here, it should be noted that there are two situations in which the interface c is displayed. In the first type, the mobile phone 100 jumps from interface b to interface c in response to user operation c on interface b. That is, in the first case, event a is user's operation c on interface b.

Exemplarily, the control e is the control 1018 shown in (b) in FIG. 10B , and the operation c is the user's click operation on the control 1018 . The mobile phone 100 may display the interface 1031 shown in FIG. 10D in response to the user's click operation on the control 1018 shown in (b) in FIG. 10B . The interface 1031 is a viewfinder interface before starting the dual-camera video recording. The interface 1031 includes preview images captured by two cameras, and the interface 1031 also includes five fragment options of 2.5 second (s) movie fragments (the five options in the dotted line box 1032). That is, interface 1031 is interface c.

In the second type, the mobile phone 100 jumps back to interface c in response to the event that the recording of the kth movie segment is completed. Wherein, 1≤k≤n, n is the number of dynamic sub-templates included in the dynamic template a. Both k and n are positive integers. That is to say, in the second case, event a is the event that the recording of the k-th movie segment is completed. For example, when the recording countdown (such as 2.5s) of the kth movie segment ends, event a is triggered. Wherein, the kth movie segment recorded each time may also be referred to as the first movie segment.

Exemplarily, after the first movie segment is recorded, k=1. The mobile phone 100 can display interface c. The interface c may be the interface 1041 shown in (a) of FIG. 10E . The segment option 1042 pointing to the first movie segment in the interface 1041 displays a cover, indicating that the first movie segment has been recorded.

In another example, after the recording of the second movie segment is completed, k=2. The mobile phone 100 can display interface c. The interface c may be the interface 1043 shown in (b) of FIG. 10E . The fragment option 1042 pointing to the first movie fragment and the fragment option 1044 pointing to the second movie fragment in the interface 1043 display cover art, indicating that both the first movie fragment and the second movie fragment have been recorded.

It should be noted that the above two situations occurred successively in the process of micro-movie recording, among which, the first case corresponds to the situation of entering the interface c for the first time during the micro-movie recording process, and the second case corresponds to the micro-movie recording process. After the recording of a movie clip, enter the situation of interface c again.

In some embodiments of the above two cases, the interface c further includes a window b, and the window b is used to play the animation effects of each animation sub-template in the animation template a. Specifically, what is played in window b is the animation effect of the motion effect sub-template (such as the first motion effect sub-template) corresponding to the movie segment to be recorded. In this way, it is beneficial to adjust the framing of the movie segment to be recorded with reference to the animation effect played in the window b during the recording preparation stage.

Exemplarily, the interface c is the interface 1031 shown in FIG. 10D , and the window b is the window 1034 in the interface 1031 . What is highlighted in the interface 1031 is the template option 1033 , that is, the first movie segment to be recorded is to be recorded, and the animation sub-template corresponding to the first movie segment is played in the window 1034 .

It should be noted that when all the movie clips have been recorded, there is no need to adjust the framing, and thus the window b is no longer displayed in the interface c.

Moreover, in this embodiment, the mobile phone 100 may hide the window b in response to the user's closing operation on the window b. This simplifies interface elements and is more conducive to previewing.

After the mobile phone 100 displays the interface c, recording preparations can be performed in the interface c. After the preparation is completed, it can be triggered to enter the recording. Record multiple movie clips in sequence, and at the same time need to use each animation sub-template to sequentially perform animation processing on the real-time images collected in each movie clip. Specifically, for the kth movie segment, the recording process is as shown in S1022 below:

S1022. The mobile phone 100 displays the interface d in response to the user's operation e on the interface c. The operation e is used to trigger the mobile phone 100 to start recording the kth movie segment. The k-th movie segment is any one of the plurality of movie segments. The kth movie segment corresponds to the first motion effect sub-template. The interface d is a viewfinder interface where the mobile phone 100 is recording video, and the interface d includes a preview image a and a preview image b. The preview image a is obtained by the mobile phone 100 using the first dynamic effect sub-template to perform dynamic effect processing on the real-time image a collected by the camera c, and the preview image b is obtained by the mobile phone 100 using the first dynamic effect sub-template to process the real-time image b collected by the camera d. Motion effect processing obtained.

Wherein, the segment option of the kth movie segment may be automatically selected by the mobile phone 100 in sequence, or may be manually selected by the user.

In the scene where the mobile phone 100 sequentially and automatically selects the segment option of the kth movie segment, the operation e may be the user's preset gesture d on the interface c. For example, a swipe gesture from bottom to top. Alternatively, the interface c includes a control f (control 1035 shown in FIG. 10D ), and the control f is used to trigger the mobile phone 100 to start dual-camera recording. The operation e is a trigger operation (such as a click operation, a long press operation, etc.) on the control f.

In the scenario where the user manually selects the segment option of the k-th movie segment, the operation e may include the user's selection operation on the segment option of the k-th movie segment, and the user's preset gesture d on the interface c. For example, the preset gesture c is a sliding gesture from bottom to top. Alternatively, the interface c includes a control f, and the control f is used to trigger the mobile phone 100 to start recording. The operation e may include the user's selection operation of the segment option of the kth movie segment, and the user's operation of clicking or long pressing the control f.

As an example, take operation e as an example where the user clicks on the segment option 1033 in the interface 1031 in FIG. 10D . The mobile phone 100 may display the interface 1051 shown in FIG. 10F in response to the user's click operation on the segment option 1033 in the interface 1031 in FIG. 10D . The interface 1051 is a viewfinder interface where the mobile phone 100 is recording, and the interface 1051 includes a preview image 1053 obtained by performing dynamic processing on the real-time image a collected by the camera c (such as a rear camera) by the mobile phone 100 using the first dynamic sub-template, and The mobile phone 100 uses the first dynamic effect sub-template to perform dynamic effect processing on the real-time image b captured by the camera d (such as the front camera) to obtain a preview image 1054 . That is, interface 1051 is interface d.

Wherein, the preview image a and the preview image b displayed on the interface d are both preview images after dynamic effect processing. In this way, the effect after the motion effect processing can be viewed in real time from the interface d during the recording process.

In some embodiments, the interface d further includes prompt information a, and the prompt information a is used to prompt the skill of recording dynamic video. For example, the interface d is the interface 1051 shown in FIG. 10F , and the interface 1051 includes a prompt 1052 , and the specific content is: automatically shoot a dynamic video without the user moving the mobile phone 100 . This can prompt the skill of recording dynamic video. That is, the presentation 1052 is presentation information a.

In some embodiments, the interface d also includes a recording countdown of the kth movie segment. In this way, the remaining recording duration of the kth movie segment can be clearly prompted.

Normally, during the dual-lens video recording process, the mobile phone 100 can switch the viewfinder frames of the two cameras in the viewfinder interface in response to the user's operation f, so as to realize the flexible adjustment of real-time images. Wherein, operation f may also be referred to as a sixth operation.

However, in some embodiments of the present application, in order to make the preview in the interface d completely consistent with the animation effect of the animation sub-template corresponding to the kth movie segment, the mobile phone 100 shields the user from operating f on the interface d. The operation f is used to trigger the viewfinder frame of the camera c and the viewfinder frame of the camera d in the interchange interface d of the mobile phone 100 . In other words, the mobile phone 100 does not respond to the user's operation f on the interface d. In this way, inconsistency between the obtained preview and the animation effect of the animation sub-template corresponding to the k-th movie segment due to swapping during the animation processing process can be avoided. This improves the consistency of before and after previews.

Wherein, the operation f may be a double-click operation on the preview image a or the preview image b, or a drag operation on the preview image a or the preview image b.

When the recording countdown of the kth movie segment ends, event a will be triggered, and then return to S1021, and interface c will be displayed. Then the mobile phone 100 responds to the user's operation e on the interface c, displays the interface d, and enters the recording of the next movie segment. This cycle goes on and on until all n movie clips are finally recorded, and the cycle ends.

S1023. The mobile phone 100 generates a video file a in response to the event c. The event c is used to trigger the mobile phone 100 to save a video with a dynamic effect. The video file a includes n sections of the first video stream and n sections of the second video stream, wherein the kth section of the first video stream includes the multi-frame preview image a processed in the kth movie segment, and the kth section of the second video stream The stream includes the multi-frame preview image b processed in the kth movie segment.

Wherein, the event c may be an event automatically triggered by the mobile phone 100 . For example, after n movie clips are all recorded, event a is triggered. Alternatively, the event c may also be an event triggered by a user. For example, after all n movie clips are recorded, the interface c displayed by the mobile phone 100 includes a control g, and the control g is used to trigger the mobile phone 100 to save a video with a dynamic effect. The event c may be a user's trigger operation on the control g (such as a click operation, a long press operation, etc.). For another example, after all n movie clips are recorded, the interface c displayed by the mobile phone 100 includes a control h, and the control h is used to trigger the mobile phone 100 to display the control i and the control j in the interface c. Wherein, the control i is used to trigger the mobile phone 100 to save the video with the dynamic effect, and the control j is used to trigger the mobile phone 100 to delete the video with the dynamic effect. Event c is a trigger operation (such as click operation, long press operation, etc.) on control i.

Exemplarily, taking n=5 as an example, after all five movie clips are recorded, the mobile phone 100 may display the interface 1061 shown in (a) in FIG. 10G . The interface 1061 includes a control 1062 . The control 1062 can be used to trigger the mobile phone 100 to display the control i and the control j, that is, the control 1062 is the control h. In response to the user's click operation on the control 1062, the mobile phone 100 may further display a control 1063 and a control 1064 on the interface 1061 as shown in (b) of FIG. 10G . Wherein, the control 1063 is used to trigger the mobile phone 100 to delete the video with a dynamic effect, that is, the control 1063 is the control j. The control 1064 is used to trigger the mobile phone 100 to save a video with a dynamic effect, that is, the control 1064 is control i.

Then, the mobile phone 100 generates video file a in response to event c. In some embodiments, in response to the event c, the mobile phone 100 may display prompt information b on the interface c, where the prompt information b is used to prompt the progress of generating the video file. In this way, the saving progress can be intuitively displayed.

Exemplarily, the event c is the user's click operation on the control 1064 in the interface 1061 shown in (b) in FIG. 10G, and the mobile phone 100 responds to the user's click operation on the control 1064 shown in (b) in FIG. , a prompt 1065 as shown in (c) in FIG. 10G may be further displayed on the interface 1061, and the prompt 1065 prompts that the progress of generating the video file is 25%. level, prompt 1065 is prompt information b.

Exemplarily, as shown in FIG. 10H , the video file a includes n segments of the first video stream, namely: the first segment of the first video stream, the second segment of the first video stream...the nth segment of the first video stream. Among them, splicing all the preview images a in the first movie segment (such as the first 2.5s) in time sequence can obtain the first segment of the first video stream, and the second movie segment (such as the second 2.5s ) splicing all preview images a in time sequence to obtain the second segment of the first video stream... splicing all preview images a in the nth movie segment (such as the nth 2.5s) in time sequence to obtain the nth segment First video stream.

Moreover, the video file a further includes n sections of second video streams, namely: the first section of the first video stream, the second section of the first video stream...the nth section of the first video stream. Among them, splicing all the preview images b in the first movie segment (such as the first 2.5s) in time sequence can obtain the first segment of the second video stream, and the second movie segment (such as the second 2.5s ) all the preview images b of ) can be spliced in time sequence to get the second segment of the second video stream... All the preview images b in the nth movie segment (such as the nth 2.5s) can be spliced in time sequence to get the nth segment Second video stream.

Finally, the mobile phone 100 generates n segments of the first video stream and n segments of the second video stream. In this way, a video file with a dynamic effect is obtained.

To sum up, using the method of the embodiment of the present application, during the process of dual-lens video recording, the mobile phone 100 can perform dynamic processing on the real-time images collected by the two cameras in real time according to the dynamic template selected by the user, and obtain A preview image of is displayed in the viewfinder interface during recording. In this way, the difficulty of recording a video with a dynamic effect can be reduced. Moreover, the result after the dynamic effect processing can be presented to the user in real time, which is conducive to previewing the recorded result in real time.

After the recording is finished, the mobile phone 100 generates a video file a with a dynamic effect. In this way, videos with dynamic effects can be obtained intelligently.

In addition, after the user enters the multi-camera recording mode for the first time, or before or when the user uses various functions in the aforementioned embodiments for the first time, the mobile phone 100 can guide the user to use them. Thus, the efficiency of human-computer interaction can be improved.

Taking entering the multi-mirror recording mode for the first time as an example, in order to guide the user to switch the multi-mirror mode, after the user selects the multi-mirror recording mode for the first time, the mobile phone can use pop-up windows, bubbles, etc. to prompt guidance information to prompt switching to the multi-mirror mode. Among them, the key switching operation is mainly prompted. In this way, the experience of human-computer interaction can be improved.

Exemplarily, in response to the user's first selection operation of the multi-mirror recording mode, the mobile phone displays the viewfinder interface 1101 of the front and rear dual-mirror mode shown in (a) of FIG. 11A . It should be noted that during the first-time booting process, a mask layer will be added to the viewfinder interface, and a prompt message will be displayed on the mask layer to achieve a strong reminder. The viewing interface 1101 includes prompt information 1102, and the prompt information 1101 is used to prompt to switch the multi-mirror mode (also called the recording mode). The prompt information 1102 includes effect video, text prompt and operation options. Wherein, the effect video is used to indicate the effect of the video recorded by switching the multi-mirror mode. The text prompt is used to prompt the entrance to switch the multi-mirror mode. For example, the text prompt information may be "click (the mode icon) to switch the recording mode" shown in (a) in FIG. 11A . The operation options further include a first option and a second option, the first option is used to trigger the exit of the boot, and the second option is used to trigger the continuation of the boot. For example, the first option can be the "try again later" button shown in (a) in Figure 11A, and the second option can be the "record a section" button shown in (a) in Figure 11A, that is, the second option .

The mobile phone can cancel the mask effect in response to the user's click operation on the first option shown in (a) in FIG. 11A . In response to the user's click operation on the second option shown in (a) in FIG. 11A , the mobile phone may display the viewfinder interface 1103 shown in (b) in FIG. 11A . The viewfinder interface 1103 includes prompt information 1104, and the prompt information 1104 is used to prompt the operation of selecting the multi-mirror mode. For example, the specific content of the prompt information 1104 may be "click here to switch to rear and rear mirrors". Moreover, in the viewfinder interface 1103, only the mode option pointed to by the prompt information 1104, that is, the mode option 1105 is in an operable state and can respond to the user's selection operation.

In response to the user's selection operation on the mode option 1105 shown in (b) in FIG. 11A , the mobile phone may display a viewfinder interface 1106 in the rear and rear dual-mirror mode shown in (c) in FIG. 11A . The viewfinder interface 1106 includes prompt information 1107 . The prompt information 1107 is used to prompt to start recording video. For example, the specific content of the prompt information 1107 may be "click here to switch to start recording". Moreover, in the viewfinder interface 1106, only the recording start control 1108 pointed to by the prompt information 1107 is in an operable state, and can respond to the user's click operation.

Then, the mobile phone can start recording video in response to the user's click operation on the start recording control 1108 .

In the subsequent recording process, the key switching operation can also be prompted. For example, the panel display control is an arrow with a dynamic effect, and the dynamic effect can guide the user to slide up to select the panel, thereby switching the multi-mirror mode. The prompts during the recording process are similar to the prompts before the recording, so there will be no more examples here.

The following is a complete example to illustrate the guidance process of using the multi-camera recording mode for the first time: when using the multi-camera recording mode for the first time, the mobile phone adds a mask in the viewfinder interface, and introduces the effect of the multi-camera recording through a pop-up window. The pop-up window does not disappear under any operation. It should be noted that under the mask effect, the user can only operate the interface elements pointed to by the guidance information (such as icons or controls, etc.), while other interface elements are inoperable, so that accurate guidance can be realized. The mobile phone cancels the mask effect in response to the user's click operation on the first option in the pop-up window. In response to the user's click operation on the second option in the pop-up window, the mobile phone can guide the user to use the multi-camera video recording mode through tutorial guidance. Specifically, the tutorial-style guidance process is as follows: under the mask effect, the user is guided to click the mode icon to switch the multi-mirror mode. In response to the user's click operation on the mode icon, the mobile phone can pop up a selection panel, which also guides the user to switch to a single-lens mode (such as a single front mode or a single rear mode) under the mask effect. In response to the user's selection of the single rear mode, the mobile phone may guide the user to click the start recording button under the mask effect. The mobile phone can start recording in response to the user's operation of clicking the start recording button, and continue to guide the user to switch the multi-mirror mode by sliding up the selection panel through the mask effect. In response to the user's upward swipe operation, the mobile phone can display a selection panel, which includes a variety of multi-mirror mode options, and guides the user to switch to the front and rear dual-mirror mode through a mask. In response to the user's selection operation of the front and rear dual-mirror mode, the mobile phone displays the viewfinder interface where the front and rear dual-mirror are recording, and guides the user to slide down to close the selection panel through the mask. In response to the user's swipe operation, the mobile phone retracts the selection panel, and guides the user to click the stop recording button through the mask. The mobile phone may end the recording in response to the user's operation of clicking the stop recording button. After the recording is finished, the mobile phone displays the viewfinder interface before recording in the front and rear dual-mirror mode, and the video is automatically saved to the album, and a bubble prompts the user that it has been saved to the album. It should be noted that during the above-mentioned tutorial-style booting process, an exit control is always provided on the mask, and the exit control is used to trigger the mobile phone to exit the booting process. In response to the user's click operation on the exit control, the mobile phone no longer displays the guidance information. That is, exit boot.

It should be noted that after the multi-mirror recording mode is not selected for the first time, for example, if the function of switching the multi-mirror mode has not been used for a long time, the mobile phone may also prompt the user to switch the multi-mirror mode. But different from the first hint, the weak hint is only given by bubbles in the non-first-time process. Therefore, strong interference to the user can be avoided.

Exemplarily, still taking the switching of the multi-mirror mode as an example, in the case that the user has not used the function of switching the multi-mirror mode for a long time, the mobile phone responds to the user's selection operation of the multi-mirror recording mode, and may display the The viewfinder interface 1111 of the front and rear dual-mirror mode, and the viewfinder interface 1111 includes prompt information 1112 in the form of bubbles. The specific content of the prompt message 1112 is "click to switch recording mode". This prompts to switch the multi-mirror mode.

Embodiment eight

When actually shooting videos, users are very likely to shoot in landscape mode. However, in the horizontal screen shooting scene, if the elements in the viewfinder interface are displayed according to the layout in the vertical screen scene, during the video recording process, if the user uses one hand to hold the phone, the other hand will input more switches. Mirror mode, adjusting playback speed, zooming and other operations, the other hand is very likely to be in the mirror. This will affect the video effect.

Before describing the above technical problems and the solutions of the embodiments of the present application in detail, the orientation of the screen of the mobile phone 100 in the landscape state is explained as follows in conjunction with (a) in FIG. 12A and (b) in FIG. 12A .

As shown in (a) in Figure 12A, the mobile phone 100 is placed with the top up and the bottom down. (b) shows the landscape state. As shown in (b) in Figure 12A, on the plane where the mobile phone 100 is located, the top of the mobile phone 100 can be called the left edge of the screen, and the bottom of the mobile phone 100 can be called the right edge of the screen. The edge above the vertical line is the upper edge of the screen of the mobile phone 100 , and the edge below the vertical line at the top or bottom of the mobile phone 100 is the lower edge of the screen of the mobile phone 100 . Similarly, in the case shown in (a) in FIG. 12A , the mobile phone 100 can be rotated to a landscape orientation as shown in (c) in FIG. 12A when the mobile phone 100 is rotated clockwise by a preset angle, such as 90°. As shown in (c) in Figure 12A, on the plane where the mobile phone 100 is located, the top of the mobile phone 100 can be called the right edge of the screen, and the bottom of the mobile phone 100 can be called the left edge of the screen. The edge above the vertical line is the upper edge of the screen of the mobile phone 100 , and the edge below the vertical line at the top or bottom of the mobile phone 100 is the lower edge of the screen of the mobile phone 100 .

It should be understood that the postures of the mobile phone 100 in the landscape state shown in (b) in FIG. 12A and (c) in FIG. 12A are exemplary, and in actual implementation, the landscape state may not be the ( b) and (c) in Figure 12A show the ideal state. For example, in the case shown in (a) in FIG. 12A , when the clockwise rotation angle of the mobile phone 100 is greater than 45° and less than 135°, the mobile phone 100 will be in the landscape state.

On this basis, the following will combine a specific scene to illustrate the problems that will be caused when the elements in the viewfinder interface are displayed according to the layout in the vertical screen scene in the horizontal screen shooting scene:

Exemplarily, during the video recording process, as shown in (a) of FIG. 12B , the user holds the bottom of the mobile phone 100 with his right hand. Under this premise, since the mode icon is located near the top of the mobile phone 100, if the mode icon is to be operated, as shown in (b) in FIG. 100 mode icons near the top to operate. At this time, the fingers of the left hand may be in the mirror. For example, the finger 1201 is the part entering the mirror. Moreover, the finger 1201 in the mirror will block the viewfinder of the building, resulting in loss of viewfinder.

Based on this, the embodiment of the present application provides a video shooting method, which can be applied to the mobile phone 100 . In this embodiment, the mobile phone 100 can adaptively adjust the display layout of the interface elements according to whether the mobile phone 100 is held by the left hand or the right hand in the horizontal screen scene. In this way, the situation of finger pointing to the mirror during recording can be avoided.

The following describes the two situations of left-hand holding and right-hand holding respectively:

The first one is the case where the right hand is held.

The mobile phone 100 detects whether the mobile phone 100 is in the first posture. Wherein, the first posture refers to a posture in which the mobile phone 100 is held by the user's right hand in a horizontal screen state. For example, what is shown in (a) in FIG. 12C is a form of the first posture. In the first gesture, the distance between the bottom of the screen and the user's right hand is smaller than the distance between the top of the screen and the user's right hand. That is to say, in the first posture, the bottom of the screen is closer to the right hand. Wherein, the mobile phone 100 can determine the attitude of the mobile phone 100 through data such as the detection result of the gravity sensor and the reflection coefficient of the antenna. In a specific implementation manner, the deflection angle of the mobile phone 100 may be detected by a gravity sensor, so as to determine the attitude of the mobile phone 100 . In another specific implementation manner, the attitude of the mobile phone 100 may be determined according to the reflection coefficient of the antenna.

Since the camera is usually set near the top of the mobile phone 100, that is to say, in order to avoid finger pointing, the user will hold the bottom of the mobile phone 100 with one hand instead of the top of the mobile phone 100 when holding it with one hand. Therefore, when the mobile phone 100 is in the first posture, if the mobile phone 100 is held with one hand, the mobile phone 100 is usually held with the right hand. Based on this, the first gesture may also be referred to as a first holding state, which is used to indicate that the right hand is holding the mobile phone.

In this case, in the viewfinder interface during recording in the multi-camera recording mode, the mobile phone 100 can mainly display the interface elements near the bottom of the mobile phone 100 to facilitate right-hand operation. In this way, the fingers will not be pointed out by the mirror due to the left-hand grip.

In some embodiments, the mobile phone 100 may display front and rear camera switching controls, pause recording controls, end recording controls, camera controls and/or panel display controls near the right edge of the screen for right-hand operation.

Exemplarily, when the mobile phone 100 is in the first posture, the mobile phone 100 may display the viewfinder interface 1211 shown in (a) of FIG. 12C during recording in the front and rear dual-mirror mode. In the viewfinder interface 1211, the front and rear camera switch control 1212, the pause recording control 1213, the end recording control 1214, the camera control 1215 and the panel display control 1216 are all displayed near the bottom of the mobile phone 100.

In some other embodiments, the mobile phone 100 may display a mode icon (also referred to as the first control), a double speed logo (also referred to as the third control) and/or a flashlight icon (also referred to as the fourth control) on the The upper edge of the screen, the area near the right edge of the screen, is convenient for right-handed operation. Wherein, for convenience of description, the upper edge of the screen and the area close to the right edge of the screen may be referred to as the first area.

Exemplarily, continuing the example of (a) in FIG. 12C , in the viewfinder interface 1211, the mode icon 1217, the double speed logo 1218 and the flashlight icon 1219 are all displayed on the upper edge of the screen, near the right edge of the screen, Convenient for right-handed operation.

In other embodiments, the mobile phone 100 can display the zoom control (also referred to as the second control) on the lower edge of the screen, near the left edge of the screen, so that the left hand can easily zoom in without holding the top of the mobile phone 100. , convenient for zoom adjustment. Wherein, the lower edge of the screen and the area close to the left edge of the screen may be referred to as the second area.

Exemplarily, using the aforementioned example of (a) in FIG. 12C , the zoom control 1210 is displayed at the lower edge of the screen, near the top of the screen. As shown in (b) of FIG. 12C , when the user is holding the mobile phone 100 in the right hand, the user can complete the zoom adjustment by operating the zoom control with the index finger of the left hand. In a high probability, the user will not complete the zoom adjustment by holding the top of the mobile phone 100 with the left hand.

In some other embodiments, the mobile phone 100 may display the recording timing near the junction of the left edge of the screen and the upper edge of the screen. This makes it easy to check the timing. Wherein, for the convenience of description, the area near the junction of the left edge of the screen and the upper edge of the screen may be referred to as the fifth area.

Exemplarily, following the example of (a) in FIG. 12C , the recording timing, such as "00:00", is displayed near the junction of the left edge and the upper edge of the screen.

In some other embodiments, in the picture-in-picture mode, a small window (also referred to as a second window) is displayed below the recording timing. In this way, while the recording timing can be displayed near the junction of the left edge and the upper edge of the screen, the blocking of the timing by the small window can be avoided. In addition, for convenience of description, the large window may be referred to as the first window, and the first window is a full-screen window.

Exemplarily, when the mobile phone 100 is in the first posture, the mobile phone 100 may display the viewfinder interface 1221 shown in (c) of FIG. 12C during recording in the picture-in-picture mode. In the viewfinder interface 1221, the recording timing, such as "00:00", is displayed near the junction of the left edge and the upper edge of the screen, and the small window 1222 is displayed below the recording timing.

The second is the case of holding in the left hand.

The mobile phone 100 detects whether the mobile phone 100 is in the second posture. Wherein, the second posture refers to a posture in which the mobile phone 100 is held by the left hand in a horizontal screen state. For example, what is shown in (a) in FIG. 12D is a form of the second gesture. In the second gesture, the distance between the bottom of the screen and the user's left hand is smaller than the distance between the top of the screen and the user's left hand. That is to say, in the first posture, the bottom of the screen is closer to the left hand. Wherein, the mobile phone 100 can determine the attitude of the mobile phone 100 through data such as the detection result of the gravity sensor and the reflection coefficient of the antenna. In a specific implementation manner, the deflection angle of the mobile phone 100 may be detected by a gravity sensor, so as to determine the attitude of the mobile phone 100 . In another specific implementation manner, the attitude of the mobile phone 100 may be determined according to the reflection coefficient of the antenna.

Since the camera is usually set near the top of the mobile phone 100, that is to say, in order to avoid finger pointing, the user will hold the bottom of the mobile phone 100 with one hand instead of the top of the mobile phone 100 when holding it with one hand. Therefore, when the mobile phone 100 is in the second posture, if the mobile phone 100 is held with one hand, the mobile phone 100 is usually held with the left hand to avoid pointing fingers at the mirror. Based on this, the second posture may also be referred to as a second holding state, which is used to indicate that the left hand holds the mobile phone.

In this case, in the viewfinder interface during recording in the multi-camera recording mode, the mobile phone 100 can mainly display the interface elements near the bottom of the mobile phone 100 to facilitate operation by the left hand. In this way, the fingers will not be pointed out by the right hand.

In some embodiments, the mobile phone 100 can display front and rear camera switching controls, pause recording controls, end recording controls, camera controls and/or panel display controls near the left edge of the screen for easy operation by the left hand.

Exemplarily, when the mobile phone 100 is in the second posture, the mobile phone 100 may display the viewfinder interface 1231 shown in (a) of FIG. 12D during recording in the front and rear dual-mirror mode. In the viewfinder interface 1231 , front and rear camera switch control 1232 , pause recording control 1234 , end recording control 1233 , camera control 1235 and panel display control 1236 are all displayed near the left edge of the screen.

In some other embodiments, the mobile phone 100 may display a mode icon (also referred to as the first control), a double speed logo (also referred to as the third control) and/or a flashlight icon (also referred to as the fourth control) on the The upper edge of the screen and the area near the left edge of the screen are convenient for left-handed operation. Wherein, for convenience of description, the upper edge of the screen and the area close to the left edge of the screen may be referred to as the third area.

Exemplarily, continuing the example of (a) in FIG. 12D , in the viewfinder interface 1231, the mode icon 1237, the double speed logo 1238 and the flashlight icon 1239 are all displayed on the upper edge of the screen, near the left edge of the screen, Convenient for left-handed operation.

In some other embodiments, the mobile phone 100 may display the zoom control (also referred to as the second control) on the lower edge of the screen, near the right edge of the screen, so that the right hand can easily zoom in without holding the top of the mobile phone 100. , convenient for zoom adjustment. Wherein, for the convenience of description, the lower edge of the screen and the area close to the right edge of the screen may be referred to as the fourth area.

Exemplarily, following the example of (a) in FIG. 12D , the zoom control 1230 is displayed on the lower edge of the screen, near the right edge of the screen, and when the user holds the mobile phone 100 in the left hand, the right index finger operates The zoom control can be used to complete the zoom adjustment, and the user will not complete the zoom adjustment by holding the top of the mobile phone 100 with the right hand in a high probability.

In some other embodiments, the mobile phone 100 may display the recording timing near the junction of the upper edge and the right edge of the screen. This makes it easy to check the timing. Wherein, for the convenience of description, the area near the junction of the upper edge and the right edge of the screen may be referred to as the sixth area.

Exemplarily, following the example of (a) in FIG. 12D , the recording timing, such as "00:00", is displayed near the junction of the upper edge and the right edge of the screen.

In some other embodiments, in the picture-in-picture mode, a small window (also referred to as a second window) is displayed below the recording timing. In this way, while the recording timing can be displayed near the junction of the upper edge and the right edge of the screen, the blocking of the timing by the small window can be avoided.

Exemplarily, when the mobile phone 100 is in the first posture, the mobile phone 100 may display the viewfinder interface 1241 shown in (b) of FIG. 12D which is being recorded in the picture-in-picture mode. In the viewfinder interface 1241, the recording timing, such as "00:00", is displayed near the junction of the upper edge and the right edge of the screen, and the small window 1242 is displayed below the recording timing.

It should be noted that, in the horizontal screen state, the implementation scheme that the layout of the interface elements will change accordingly when the left and right hands are held, can be applied to various multi-mirror modes of multi-mirror video recording. That is to say, this solution can be applied to each viewing interface involved in the embodiments herein. For example, the viewfinder interface of front and rear dual-mirror mode, picture-in-picture mode, rear-rear dual-mirror mode, single front mode, and single rear mode.

Further, the difference from the vertical screen state is: in the horizontal screen state, after the mobile phone 100 is triggered to display the selection panel, the display area of the selection panel may exist with the display area of the panel display controls, mode icons, double-speed icons and/or flashlight icons. overlapping.

Exemplarily, taking the front and rear dual-mirror mode as an example, the mobile phone 100 may display the mode icon 1217 in the viewfinder interface 1211 shown in (a) of FIG. (a) shows the finder interface 1251. The viewfinder interface 1251 includes a selection panel 1252 , and the display area of the selection panel 1252 covers the display area of the panel display control, the display area of the double speed icon 1253 and the display area of the flash icon 1254 .

In some embodiments, after the selection panel is displayed, the background of the selection panel may be set to have a transparent background, so as to avoid interference with the preview. At the same time, the transparent background may make the mode icon 1253 and the flash icon 1254 partially visible which are obscured. For example, in the viewfinder interface 1251 shown in (a) of FIG. 12E , the background of the selection panel 1252 is transparent. Thus making the mode icon 1253 and the flash icon 1254 covered by the selection panel 1252 partially visible.

It should be understood that partially visible controls, mode icons, double-speed icons and/or flashlight icons on the covered panel may interfere with the use of the user. For example, the user cannot identify exactly which icon is partially displayed.

Based on this, in some embodiments, while displaying the selection panel, the mobile phone 100 can determine that there is overlap with the display area of the selection panel according to the display area of the selection panel in the viewfinder interface and the display area of each interface element in the viewfinder interface. target element.
