Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The video recording method and apparatus, the electronic device, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, a video recording method provided in an embodiment of the present application includes:

step 101, displaying a first shooting preview interface of a first camera;

and 102, shooting the first moving object through a second camera under the condition that the first shooting preview interface comprises the first moving object, wherein the focal length of the second camera is greater than that of the first camera.

The video recording method provided in the embodiment of the present application may be applied to electronic devices such as a mobile terminal, a personal computer, or a wearable device, and the like, which is not limited herein.

The electronic device may include a display screen and a plurality of cameras. The display screen can be used for displaying a shooting preview interface or playing videos and the like. The plurality of cameras can comprise a first camera and a second camera, and the focal length of the second camera is larger than that of the first camera.

In step 101, the electronic device may display a first shooting preview interface of a first camera.

In combination with an application scenario, when receiving an input for starting a video shooting application program, the electronic device may default to display a shooting preview interface of the first camera, that is, the first shooting preview interface.

In other application scenarios, the electronic device may switch the first shooting preview interface displayed as the first shooting camera in response to a selection input of the user for the shooting mode when the shooting preview interface of another camera is displayed.

Of course, the above is an illustration of some trigger conditions for the electronic device to display the first shooting preview interface of the first camera, and in practical applications, the electronic device may also display the first shooting preview interface of the first camera under other conditions.

In the case where the first photographing preview interface with the first camera is displayed, the electronic device may detect a moving object in the first photographing preview interface.

For example, the electronic device may obtain preview images from a first shooting preview interface according to a preset frequency, and by performing target detection on the preview images, the electronic device may detect an object in each preview image. According to the position change of the object in the plurality of preview images, the electronic equipment can further judge whether the object is a moving object.

For another example, the electronic device may determine whether a moving object exists in the first shooting preview interface by comparing changes of pixels in the preview images, or acquiring optical flow information between the preview images.

On the basis that the electronic device can detect the moving object in the first shooting preview interface, in step 102, the electronic device may shoot the first moving object through the second camera if the first shooting preview interface includes the first moving object.

The first moving object may refer to any moving object in the first photographing preview interface, and in this case, the electronic device may photograph the moving object through the second camera as long as the moving object is detected in the first photographing preview interface.

Alternatively, the first moving object may also refer to a preset moving object.

For example, in order to capture a video of eagle predation, the user may preset the eagle as a first moving object. When the eagle is in a flying state and appears in the first shooting preview interface, the electronic equipment can shoot the eagle through the second camera.

For another example, in order to capture a video of a motorcycle passing through a track, the user may set the motorcycle as a first moving object in advance. When the motorcycle is in a driving state and appears in the first shooting preview interface, the electronic equipment can shoot the motorcycle through the second camera.

Generally, when the imaging position and the subject distance are not changed, the smaller the focal length of the camera, the wider the angle of view, and the larger the imaging range, the smaller the image formed by the subject. Conversely, the larger the focal length of the camera, the narrower the angle of view, and the smaller the imaging range, the larger the image formed by the object.

Accordingly, the first camera has a relatively small focal length, a relatively large shooting range can be obtained, and the electronic device is facilitated to detect the first moving object from the first shooting preview interface more efficiently. And when the first shooting preview interface comprises the first moving object, the first moving object is shot through the second camera with a larger focal length, so that the electronic equipment can better capture the detailed information of the first moving object.

By combining the example of the video recording scene of the hawk predation, the electronic equipment can display the first shooting preview interface of the first camera in the initial stage, and the video recorded in the initial stage can have a larger shooting range.

When the hawk appears on the first shooting preview interface, the electronic equipment can shoot the hawk by adopting the second camera with a larger focal length, and at the moment, the hawk can have a larger image in the recorded video, so that the special effect of automatically amplifying the hawk is obtained, and the detailed action of the hawk on the food can be better shown.

In practical application, when a video is recorded, a user may shake when holding the electronic device, which causes the picture in the first shooting preview interface to shake. Alternatively, there may be subtle movements of theoretically stationary objects such as trees or lake water.

Therefore, according to some embodiments of the present application, in determining whether a moving object exists in the first photographing preview interface, the electronic device may perform a determination in combination with factors such as a moving speed or a moving distance of each object. For example, a speed threshold and a distance threshold may be set in the electronic device, and when the speed of the object in the first shooting preview interface is greater than the speed threshold and the position change value of the pixel area corresponding to the object is greater than the distance threshold within a preset time, the electronic device may determine that the object is a moving object, so as to improve the accuracy of detecting the moving object by the electronic device.

The following describes a video recording method provided in the embodiments of the present application with reference to some specific application examples.

As shown in fig. 2, fig. 2 is a diagram illustrating an example of an interface when the electronic device displays a first shooting preview interface. The first shooting preview interface is a shooting preview interface of a first camera with a relatively small focal length, and accordingly the first shooting preview interface has a large shooting range.

The item indicated by reference D1 in fig. 2 may be a flying bird. The electronic equipment can recognize the bird by recognizing the video image and judge that the bird is in a motion state according to the change of the position of the bird. At this time, the bird indicated by the marker D1 may be the first moving object described above.

As described above, in the case where the electronic device includes the first moving object in the first photographing preview interface, the first moving object may be photographed by the second camera having a larger focal length.

If the shooting preview interface of the second camera is referred to as a second shooting preview interface, the second shooting preview interface can be displayed when the electronic device shoots the first moving object through the second camera with a larger focal length.

In one possible embodiment, the electronic device may alternatively display the first photographing preview interface as the second photographing preview interface, at which time the display interface of the electronic device may be switched to the interface as shown in fig. 3.

As shown in fig. 3, since the focal length of the second camera is larger and the shooting range is relatively smaller, the bird indicated by the mark D1 in fig. 3 can occupy a larger display area, and more detailed contents of the bird can be displayed in the second video shooting interface.

In yet another possible embodiment, in a case where the first photographing preview interface includes the first moving object, the method further includes:

and under the condition that the first shooting preview interface of the first camera is displayed, displaying a second shooting preview interface of the second camera.

In this embodiment, when the first photographing preview interface includes the first moving object, the first photographing preview interface and the second photographing preview interface may be simultaneously displayed.

In some examples, the electronic device may display the first photographing preview interface and the second photographing preview interface by split-screen. Or, the electronic device may display the first shooting preview interface in an overlapping manner on the second shooting preview interface. Alternatively, the electronic device may display the second photographing preview interface in an overlapping manner on the first photographing preview interface, and so on. Here, the manner of simultaneously displaying the first photographing preview interface and the second photographing preview interface is not illustrated.

In practical application, when the first shooting preview interface and the second shooting preview interface are displayed in the electronic device, on one hand, a user can know the change of the surrounding environment of the first moving object from the first shooting preview interface, and on the other hand, the user can also watch the shooting effect of the second camera on the first moving object from the second shooting preview interface in real time.

Of course, in some possible embodiments, the electronic device may also continue to detect other moving objects in the first shooting preview interface, and may switch the second camera to shoot other moving objects in response to a related operation of the user, so as to enrich a video recording function of the electronic device. And the implementation of these functions will be explained in the following embodiments.

As shown in fig. 4, fig. 4 is an exemplary diagram of an interface when the electronic device simultaneously displays a first shooting preview interface and a second shooting preview interface.

The interface shown in fig. 4 may include a display region R1 and a display region R2. The first photographing preview interface is displayed in the display area R2, and the second photographing preview interface is displayed in the display area R1.

In fig. 4, the area of the display region R1 may be larger than that of the display region R2, and the display region R2 is located at the lower right side of the display region R1. In this way, while the user can preview the shooting effect of the second camera on the first moving object conveniently, the change of the surrounding environment of the first moving object can be observed through the first shooting preview interface in the display area R2.

In some possible embodiments, the first photographing preview interface may be displayed in a floating manner on the second photographing preview interface, the user may drag the first photographing preview interface to change the display position of the first photographing preview interface, and the display area R1 and the display area R2 may also be changed accordingly.

In other possible embodiments, the electronic device may also receive a preset operation of a user, and swap display areas of the first shooting preview interface and the second shooting preview interface.

In some examples, the second camera may be a variable focus camera.

For example, the second camera may be a 50-time zoom (hereinafter, referred to as 50 ×) telephoto camera. In a case where the first photographing preview interface includes the first moving object, the second camera may gradually change from a smaller focal length to a larger focal length.

With reference to fig. 2 and 3, in the process of switching the display interface of the electronic device from the interface shown in fig. 2 to the interface shown in fig. 3, the electronic device may control the shooting focal length of the second camera to gradually change from 30mm to 500mm, so that the display content in the first display region R1 can be smoothly transited.

Meanwhile, through the gradual change of the focal length of the second camera, the video picture can gradually change from the picture shot by the first camera to the detail picture of the first moving object in the recorded video, so that the improvement of the picture smoothness of the recorded video is facilitated.

In some application scenarios, a user may need to emphasize the motion of a moving object appearing in a video capture interface, for example, by slowing down the motion process of the moving object to achieve the effect of motion emphasis.

In the related art, a user may perform post-editing on a captured video to enable a video frame including a moving object to be slowly played during video playing, so as to achieve the purpose of emphasizing the moving object. This post-clipping approach has the disadvantage of being cumbersome to operate.

In order to obtain a slow-play special effect more conveniently, according to some embodiments of the present application, a recording frame rate of the second camera is greater than a recording frame rate of the first camera.

For example, the recording frame rate of the first camera is 60fps, that is, when a video is recorded by the first camera, 60 image frames can be obtained within 1 s. The recording frame rate of the second camera may be 120fps, that is, when a video is recorded by the first camera, 120 image frames can be obtained within 1 s.

In the process of recording the video, if the first moving object does not exist in the first shooting preview interface, the electronic device may keep using the first camera for shooting, and the corresponding recording frame rate is 60 fps. And when the first shooting preview interface comprises the first moving object, the electronic equipment shoots the first moving object through the second camera, and the corresponding recording frame rate is 120 fps.

From the aspect of playing the recorded video, if the video is played at the playing frame rate of 60fps, the electronic device may play the video at a normal speed when the first moving object is not included in the video. When the video includes the first moving object, if the electronic device plays the video at the same speed (60fps), the slow play special effect can be realized.

Therefore, in the embodiment, in the recording stage of the video, the electronic device can realize the switching of the recording frame rate by switching the cameras, so that the slow playing effect on the motion process of the first motion object can be obtained, and the operation complexity for obtaining the video with the slow playing special effect is reduced.

Optionally, in step 102, after the first moving object is photographed by the second camera, the method further includes:

receiving a first input of a user to a second moving object in the case that the first photographing preview interface includes the second moving object;

in response to the first input, a second moving object is photographed by a second camera.

For the convenience of understanding the implementation process of the present embodiment, the following description is also provided with reference to an example of an application scenario.

As shown in fig. 4, during the video recording process, a first shooting preview interface and a second shooting preview interface may be simultaneously displayed on the electronic device. Since the second camera has a larger focal length, the first moving object D1 in the second photographing preview interface may have a larger picture during photographing of the first moving object D1 using the second camera.

Meanwhile, the first camera can also shoot the first moving object D1, and the first camera has a smaller focal length and a larger shooting range. Accordingly, the first moving object D1 may be included in the first photographing preview interface, but the picture of the first moving object D1 is relatively small, and the first photographing preview interface may include more contents than the second photographing preview interface.

As shown in fig. 4, in practical applications, the first photographing preview interface may include a second moving object D2 in addition to the first moving object D1.

During the course of video recording, the user may need to switch the emphasized object from the first moving object D1 to the second moving object D2. From the viewpoint of the electronic apparatus, it is necessary to switch the main photographic object of the second camera from the first moving object D1 to the second moving object D2.

As shown in fig. 5, for the purpose of switching, the user may touch the second moving object D2 with a finger and slide the finger to the first display region R1. Here, the input of the user touching and sliding the second moving object D2 may correspond to the above-described first input of the user to the second moving object.

It will be readily appreciated that this is one illustration of the form of input to the first input. In practical applications, the first input may also be a single-click input or a double-click input for the second moving object, which is not illustrated here.

Of course, in practical applications, the second camera may be a zoom camera, or the first moving object and the second moving object may be located relatively close to each other. The electronic device may capture the first moving object and the second moving object simultaneously by the second camera when receiving the first input. In this case, it may be considered that the electronic device changes the subject to be shot with emphasis from the first moving subject to the first moving subject and the second moving subject, instead of switching from the first moving subject to the second moving subject.

In this embodiment, under the condition that the first shooting preview interface includes the second moving object, the electronic device may shoot the second moving object through the second camera in response to the first input of the user to the second moving object, so as to change the shot moving object in a highlight manner, and meet diversified video recording requirements of the user.

In some possible embodiments, in the case that the first photographing preview interface includes the second moving object, the method may further include:

and displaying a prompt box on the second moving object.

In connection with an example, during shooting of the first moving object using the second camera, the electronic device may continuously detect the moving object in the first shooting preview interface. As shown in fig. 6, the electronic device may display a prompt box B on a second moving object when detecting that the second moving object exists in the first photographing preview interface.

The shape and size of the prompt box can be set according to needs. By displaying the prompt box, the electronic apparatus can prompt the user to detect the second moving object that can be subjected to highlight shooting. At this time, the user may further make a first input to the second moving object or the prompt box, thereby controlling the electronic device to make a change of the moving object emphasized for shooting.

Therefore, the prompt box is displayed on the second moving object, so that the moving object which can be shot in a highlighted mode can be better prompted to the user, and the user experience is improved.

As shown in fig. 7, fig. 7 is a diagram of an example of a display interface of the electronic device when the second moving object is photographed by the second camera.

As can be seen from fig. 7, the display areas of the second photographing preview interface corresponding to the first photographing preview interface, respectively, may remain unchanged, and the emphasized object in the second photographing preview interface may be switched from the first moving object D1 to the second moving object D2.

In some possible embodiments, there may be a process of screen transition in a process of switching the emphasized object of the second photographing preview interface from the first moving object to the second moving object (corresponding to a process of changing the display interface from fig. 5 to fig. 7).

For example, on the basis of the interface shown in fig. 5, the first photographing preview interface may be gradually enlarged first to completely cover the second photographing preview interface. Then, the electronic device may switch to display the first photographing preview interface as the second photographing preview interface. And then zooming the second camera to enlarge the image size of the second moving object in the second shooting preview interface, thereby obtaining the interface shown in fig. 7.

Optionally, after displaying the second shooting preview interface of the second camera, the method further includes:

receiving a second input of the parameter adjusting control from the user under the condition that the parameter adjusting control is displayed in the second shooting preview interface;

displaying a first identifier in response to the second input, wherein the first identifier is used for indicating shooting parameters of the first moving object;

after the second moving object is shot by the second camera, the method further comprises:

receiving a third input of the first identifier from the user;

in response to a third input, a second moving object is photographed based on the photographing parameters of the first moving object.

As shown in fig. 8, fig. 8 is an exemplary diagram of a display interface of an electronic device when a parameter adjustment control is displayed in a second shooting preview interface.

The parameter adjustment control may include one or more adjustment sub-controls. Each adjustment sub-control may be used to adjust one or more shooting parameters.

As shown in fig. 8, in some examples, the parameter adjustment control may include a plurality of adjustment sub-controls (e.g., labels K1 and K2) that may be used to adjust the recording frame rate, the background blurring parameter, the background color parameter, and so on, respectively.

In other examples, the parameter adjustment control may further include an adjustment sub-control for adjusting other shooting parameters, for example, an adjustment sub-control for adjusting display parameters such as white balance, shooting filter, etc., which are not illustrated herein.

In some possible embodiments, the electronic device may display the parameter adjustment control in the second shooting preview interface when the second shooting preview interface is displayed.

Alternatively, the electronic device may also display a parameter adjustment control in the second capture preview interface, and so on, in response to an input by the user invoking the parameter adjustment control.

In an instance in which a second input to the parameter adjustment control is received by the user, the electronic device may display the first identification in response to the second input.

For example, the second input may be a long-press input for the parameter adjustment control, or a click input for a folding control associated with the parameter adjustment control, and so on, which is not limited herein.

In one example, based on the example interface diagram shown in fig. 8, the electronic device may further display the example interface diagram as shown in fig. 9 in case of receiving the second input.

As shown in fig. 9, the first identity may correspond to the identity P. In the case where the first identifier P is displayed, the electronic device may hide the above-described parameter adjustment control.

Of course, in some possible embodiments, the electronic device may also display the first identifier in a display area outside of the parameter adjustment control if the second input is received.

The first identifier is associated with the parameter adjustment control described above. For example, the parameter adjustment control is used to adjust the shooting parameters of the first moving object, and the first identifier may be used to indicate the shooting parameters of the first moving object.

In this embodiment, after the second moving object is photographed by the second camera, the electronic device may receive a third input of the first identifier by the user. For example, the third input may be a long press input to the first identifier, or other preset gesture input, etc.

The electronic device may photograph the second moving object based on the photographing parameters of the first moving object, upon receiving the third input.

In combination with an application example, when the second camera is used for shooting the first moving object, the user can input the parameter adjustment control so as to set the shooting parameters of the second camera for the first moving object to be the recording frame rate of 120fps and the shooting focal length of 500 mm.

In a case where a second input to the parameter adjustment control by the user is received, the electronic device may display a first identifier, where the first identifier may indicate that the shooting parameter of the first moving object is the recording frame rate of 120fps and the shooting focal length is 500 mm.

The electronic device may further receive a third input of the first identifier from the user after photographing the second moving object through the second camera, and photograph the second moving object using a recording frame rate of 120fps and a photographing focal length of 500mm in response to the third input.

In this embodiment, the electronic device may rapidly apply the shooting parameters of the first moving object to shoot the second moving object based on the input of the user to the first identifier, so as to improve the operation efficiency of the user.

In yet other possible embodiments, in the case that the first control is displayed, the method may further include:

and under the condition that the input of dragging the preset control to the second moving object is received, shooting the second moving object through the second camera based on the shooting parameters of the first moving object. In this way, the user can switch the main shooting object of the second camera from the first moving object to the second moving object through simple input operation, and simultaneously apply the shooting parameters of the first moving object to shoot the second moving object.

Optionally, the parameter adjustment control comprises a frame rate adjustment sub-control,

receiving a second input of the parameter adjustment control by the user, comprising:

receiving a first sub-input of a frame rate adjusting sub-control by a user;

the method further comprises the following steps:

and responding to the first sub-input, and updating the recording frame rate of the second camera.

As shown in fig. 8, the parameter adjustment control may include a frame rate adjustment sub-control K1. The user can adjust the used photographing frame rate in real time by making a first sub-input to the frame rate adjustment sub-control K1.

For example, the frame rate adjustment sub-control K1 may be a drag-type adjustment control, and the first sub-input may be a drag output to the frame rate adjustment sub-control K1. And the electronic device may update the recording frame rate of the second camera in response to a user's drag input to the frame rate adjustment sub-control K1.

For another example, the frame rate adjustment sub-control may also include two click type adjustment controls, which are respectively used to increase and decrease the recording frame rate of the second camera, and the first sub-input may be a click input to the frame rate adjustment sub-control.

Of course, the foregoing is an illustration of some forms of the frame rate adjustment sub-control, and in practical applications, the frame rate adjustment sub-control may be implemented to adjust the recording frame rate of the second camera.

In combination with some application scenarios, during the process of shooting the first moving object by using the second camera, the user may adjust the sub-control by operating the frame rate, so that the recording frame rate of the second camera is updated from 120fps to 240fps, and the like. Therefore, in the recorded video, the slow playing effect on the motion process of the first moving object can be realized.

Of course, the user may also operate the frame rate adjustment sub-control, so that the recording frame rate of the second camera is updated from 1200fps to 30 fps. Therefore, in the recorded video, the acceleration effect on the motion process of the first moving object can be realized.

In this embodiment, the parameter adjustment control includes a frame rate adjustment sub-control, and the electronic device can adjust the recording frame rate of the second camera in response to the first sub-input of the frame rate adjustment sub-control by the user, which is beneficial to obtaining a special effect of accelerated playing or slow playing in the video recording process, and reduces the operation difficulty of the user.

Optionally, the parameter adjustment control includes a background adjustment sub-control, and receives a second input to the parameter adjustment control from the user, where the second input includes:

receiving a second sub-input of the background adjustment sub-control by the user;

the method further comprises the following steps:

in response to the second sub-input, updating background image parameters corresponding to the first moving object, the background image parameters including at least one of: background blurring parameter, background color parameter.

As shown in fig. 8, the parameter adjustment control may include a background adjustment sub-control K2. The background adjustment sub-control K2 may be one or more, and each background adjustment sub-control K2 may be used to adjust a corresponding background parameter.

The background adjustment sub-control K2 may be a drag-type adjustment control or a click-type adjustment control, which is not limited in this respect. Accordingly, the first sub-input may be in the form of a drag input or a click input, and may be matched with the form of the background adjustment sub-control K2.

For example, as shown in fig. 8, the background adjustment sub-control K2 may include a background blurring adjustment sub-control and a background color adjustment sub-control, which may be used to adjust a background blurring parameter and a background color parameter, respectively.

As shown in the above embodiments, the electronic device may detect a moving object in the shooting preview interface. Accordingly, in the process of photographing the first moving object through the second camera, the electronic device may detect the first moving object and its image area, and the background area may be an image area other than the first moving object.

The background blurring adjustment is adjusted by inputting the background blurring adjustment sub-control by the user. Generally, the higher the adjusted background blurring depth is, the higher the blurring degree of the background area in the captured video image is. Under the condition that the second sub-input of the background blurring adjustment sub-control by the user is received, the electronic equipment can control the multiple cameras to shoot according to the background blurring depth, so that the depth of field information is obtained, and blurring of the background is achieved.

For another example, where a user's second sub-input to the background color adjustment sub-control is received, the electronic device may adjust the color saturation of the background region in response to the user's second sub-input. In an application scenario, the user operates the background color adjustment sub-control, so that the electronic device can adjust the background in the video image to a grayscale image background or a black-and-white background.

Of course, in other possible embodiments, the parameter adjustment control may also include some sub-controls for adjusting the filter effect, and the like, which are not illustrated herein.

In this embodiment, the parameter adjustment control includes a background adjustment sub-control, and the electronic device may update the background image parameter corresponding to the first moving object in response to the second sub-input when receiving the second sub-input to the background adjustment sub-control, so as to help obtain special effects such as background blurring or background color change during the video recording process, and reduce the operation difficulty of the user.

Optionally, after the first moving object is photographed by the second camera, the method further includes:

and outputting a target video, wherein the target video comprises a first video and a second video, the first video is a video obtained by recording through a first camera, the second video is a video obtained by recording through a second camera, the playing frame rate of the second video is equal to the playing frame rate of the first video, and the playing frame rate is smaller than the recording frame rate of the second camera.

In conjunction with the description of the video recording process in the above embodiment, the recording frame rate of the second camera may be greater than the recording frame rate of the first camera.

In the process of recording the video, there may be a process of shooting with the first camera, and accordingly, the obtained first video may be a first video with a lower recording frame rate. When the first shooting preview interface includes the moving object, the electronic device may shoot the moving object by using the second camera, and accordingly, the obtained second video may be a second video with a higher recording frame rate.

In this embodiment, after the first moving object is photographed by the second camera, a target video including the first video and the second video may be output. And in the target video, the playing frame rate of the first video and the playing frame rate of the second video may be equal.

For example, in combination with one example, the recording frame rate of the first video may be 60fps, and the recording frame rate of the second video may be 120 fps. The playing frame rates of the first video and the second video are both 60 fps. In the process of playing the target video, when the first video is played, the electronic device may play the content at a constant speed, for example, the content shot in 5s, and the playing time may be 5 s. And when playing the second video, the electronic device may play at a slow playing speed, for example, 5s of the captured content, and the playing time may be 10 s.

It can be seen that the electronic device actually generates a special effect of slow-playing the video when the second video is played. The slow playing special effect can be obtained by directly recording the video instead of performing subsequent processing on the target video, so that the operation required by a user for obtaining the slow playing special effect can be greatly simplified.

and under the condition that the first moving object exceeds the shooting range of the second camera, canceling the display of the second shooting preview interface.

As shown in fig. 4, in one example, the electronic device may display the second video preview interface in the first display region R1 and the first video preview interface in the second display region R2 in a case where the first moving object D1 is detected.

And when the first moving object D1 exceeds the shooting range of the second camera, the overall display interface of the electronic device may be switched to an interface similar to fig. 2, that is, the first display region R1 of the electronic device may redisplay the first video preview interface while canceling the display of the second video preview interface.

For example, if the first moving object D1 is a flying bird, the bird flies out of the shooting range of the second camera, which may be indicated by the bird no longer being displayed in the second video preview interface or by the bird not being displayed in the first video preview interface and the second video preview interface. From another perspective, it can be considered that when no bird is detected in the second video preview interface, the electronic device determines that the first moving object is beyond the shooting range of the second camera and cancels the display of the second shooting preview interface.

With reference to some examples, in the interface shown in fig. 4, when the first shooting preview interface is displayed on the second shooting preview interface through the floating window, the manner of canceling the display of the second shooting preview interface may be to hide or close the floating window, and switch and display the first shooting preview interface in the first display area R1.

And when the first shooting preview interface and the second shooting preview interface are displayed in a split screen mode, the mode of canceling the display of the second shooting preview interface can be a mode of canceling the split screen mode and reserving the first shooting preview interface.

As shown above, the first moving object may be an object that the electronic apparatus needs to perform emphasis shooting using the second camera. When the first moving object leaves the shooting range of the second camera, the electronic device may end shooting of the object that needs to be emphasized for shooting, and switch to performing normal shooting using the first camera. Therefore, the electronic equipment is facilitated to distinguish the shooting parameters of the first moving object from the shooting parameters of the conventional scene in the video recording process, and the effect of emphasizing the motion details of the first moving object is achieved.
