Step 202: the video recording device responds to the first input and records the video according to the recording mode corresponding to the input area of the first input.

In the embodiment of the present application, the input area may be any screen area on the scroll screen.

Optionally, the input area may be preset or customized by a user, and the input area may include at least two input areas, where different input areas correspond to different recording modes.

Illustratively, the input area may include a first screen control area and a second screen control area. For example, the first screen control area may be an upper half screen area or a left half screen area of a screen of a scroll screen, and the second screen control area may be a lower half screen area or a right half screen area of the screen, and the first screen control area and the second screen control area may be interchanged with each other, which is not limited in this embodiment of the present invention.

Optionally, there is no overlapping area between the first screen control area and the second screen control area, or the first screen control area and the second screen control area partially overlap.

In the video recording method provided by the embodiment of the application, the video recording device receives a first input of a user to the scroll screen, and in response to the first input, performs video recording according to a recording mode corresponding to an input area of the first input. By the method, a user can select the video recording mode independently, for example, when a large-field-of-view and high-resolution video needs to be recorded, the video recording device is triggered to start the single-screen recording mode, and when preview images at different field angles need to be checked simultaneously, the video recording device is triggered to start the split-screen recording mode. Therefore, on one hand, the definition of the recorded large-view-field video can be improved while the recording of the large-view-field video is realized, on the other hand, the limitation of recording the video by a single camera is broken through, and the multi-view video recording function is realized, for example, the function of recording the self-timer video and the long-distance video simultaneously is realized.

Optionally, in this embodiment of the application, the recording mode includes a single-screen recording mode and a split-screen recording mode.

In an exemplary mode, in a single-screen recording mode, the video recording device may display a preview image formed by fusing images acquired by a plurality of cameras in a screen display area in real time according to an expansion ratio of the scroll screen; under the split screen recording mode, the electronic equipment can respectively display preview images acquired by the plurality of cameras in real time in the screen display area according to the expansion ratio of the scroll screen.

Therefore, a user can independently select a video recording mode through the screen control area, and under the condition of selecting the single-screen recording mode, the large-view-field and high-resolution movie lens moving and recording mode is realized, so that the view field is ensured, and the recording definition of a main body can be improved; under the condition of selecting a multi-screen recording mode, the limitation of recording by a single camera can be broken through, the multi-scene recording function is realized, and the functions of self-shooting and long-shot simultaneous recording are realized.

Further optionally, in this embodiment of the application, the step 201 may include the following step 201 a:

step 201 a: the video recording device receives a first input of a user to a first screen control area of the scroll screen;

optionally, in combination with the step 201a, the step 202 may include the following step 202 a:

step 202 a: and the video recording device responds to the first input, starts the first camera to record the video according to the single-screen recording mode corresponding to the first screen control area.

Illustratively, the first screen control area may be a screen area on a side of the scroll screen close to the scroll, or a screen area on a side of the scroll screen far from the scroll; or, the first screen control area is an upper half screen area of a screen area on a side of the scroll screen close to the scroll, or a lower half screen area of the screen area on the side close to the scroll.

It should be noted that the end of the scroll screen near the scroll can also be referred to as the area where the roll is located, and the scroll screen shrinks on the scroll to form the roll.

Optionally, the first camera may be any one of: 2 focus camera, wide-angle camera, ordinary camera (for example, main camera), long-range looking camera, above-mentioned first camera can also be other cameras, and this does not do any restriction to this in this application embodiment.

For example, as shown in fig. 2, a video recording device is taken as a mobile phone. After a video recording program of the mobile phone is started, an image preview interface corresponding to a main camera is displayed in a screen display area of the mobile phone, an image collected by the main camera in real time is displayed in the image preview interface, a user clicks the upper half screen area 21 of the screen area on one side, close to a scroll, of the scroll screen to enter a single-screen recording mode, and then the user can click a video recording control to trigger the mobile phone to record a video in the single-screen recording mode.

Further optionally, in this embodiment of the present application, the step 201 may include the following step 201 b:

step 201 b: the video recording device receives a first input from a user to a second screen control area of the scroll screen.

Optionally, in combination with the step 201b, the step 202 may include the following step 202 b:

step 202 b: and the video recording device responds to the first input, starts the first camera to record the video according to the split screen recording mode corresponding to the second screen control area.

Illustratively, the second screen control area may be a screen area on a side of the scroll screen close to the scroll, or a screen area on a side of the scroll screen far from the scroll; or, the second screen control area is an upper half screen area of a screen area on a side of the scroll screen close to the scroll, or a lower half screen area of the screen area on the side close to the scroll.

Optionally, the second camera may be any one of: 2 focus camera, wide-angle camera, ordinary camera (for example, main camera), long-range looking camera, above-mentioned first camera can also be other cameras, and this does not do any restriction to this in this application embodiment.

For example, referring to fig. 2, a user clicks the lower half portion of the screen area 22 on the side of the scroll screen close to the scroll to enter a split-screen recording mode, and then the user may click the "video recording" control to trigger the mobile phone to record a video in the split-screen recording mode.

Therefore, the embodiment of the application provides a recording mode for interactively selecting videos through the scroll, a user can select a single-screen recording mode, a large-view-field and high-resolution movie lens moving and recording mode can be realized, the view field is ensured, and the recording definition of a main body can be improved; the user also can select many screen recording modes, can break through the limitation that single camera recorded, realizes the function of recording of many scenes, realizes autodyne and long shot and records the function simultaneously, promotes the interest that the user used the video recording function.

Further optionally, in this embodiment of the present application, in a case that the video recording mode is the split-screen recording mode, before the step 202, the video recording method provided in this embodiment of the present application further includes the following steps a1 and a 2:

step A1: the video recording device determines a second camera and a third camera according to the first expansion ratio of the scroll screen.

Wherein, the second camera and the third camera have different angles of view.

Step A2: the video recording device displays a first video recording interface in a first sub-display area of a screen display area of the scroll screen, and displays a second video recording interface in a second sub-display area of the screen display area of the scroll screen.

The first video recording interface is a recording interface of a second camera, and the second video recording interface is a recording interface of a third camera.

Alternatively, the first expansion ratio may be a ratio of a screen expansion length of the scroll screen to a screen length of the scroll screen contracted in the initial display state of the scroll screen.

It should be noted that the contraction or expansion ratio of the scroll screen is based on the screen contracted to the scroll when the scroll screen is in the initial display state. For example, in the initial display state, the screen is unfolded by 6cm and the portion contracted to the scroll is 10cm, and then, contracting or unfolding the scroll screen by 50% means unfolding the portion contracted to the scroll by 5 cm.

For example, the screen length of the scroll screen contracted on the scroll in the initial display state is 10cm, the expansion ratio of the scroll screen is 0 when the contracted screen is not expanded, the expansion ratio of the scroll screen is 50% after the scroll screen is stretched to expand 5cm, and the expansion ratio of the scroll screen is 100% after the screen contracted on the scroll is completely expanded.

In a specific implementation, the video recording device may start the multiple cameras to record videos and display video recording interfaces corresponding to the multiple cameras according to the expansion length of the spool screen in a multi-screen recording mode under the condition that the spool screen is in an expansion state. For example, in the case where the expansion ratio of the scroll screen is greater than or equal to 50% and less than 80%, the 2-time focal length camera and the main camera are simultaneously activated for video recording.

Optionally, the second camera and the third camera may both be any one of the following cameras: 2 focus camera, wide-angle camera, ordinary camera (for example, main camera), super wide-angle camera, this application embodiment does not do any restriction to this.

The relationship between the field angle of the camera is: the field angle of the 2-time focal length camera is smaller than that of the main camera, the field angle of the main camera is smaller than that of the wide-angle camera, and the field angle of the wide-angle camera is smaller than that of the ultra-wide-angle camera.

The larger the angle of view of the camera, the larger the range of view that can be captured, and the lower the sharpness of the obtained image frame.

Illustratively, the angle of view of the second camera is smaller than that of the third camera, i.e., the third camera can capture a larger range of images than the second camera.

Optionally, the field angle of the camera is also referred to as the field of view, and the size of the field of view determines the field of view of the optical instrument (e.g., camera).

Alternatively, the screen display area may be the entire screen display area of the scroll screen, or may be a part of the screen display area of the scroll screen. Optionally, the first sub-display area and the second sub-display area may be different display areas of the screen display area. For example, the first sub-display area and the second sub-display area may be two display areas arranged left and right or up and down in the entire screen display area. For another example, the first sub-display area and the second sub-display area are divided up and down or left and right of the scroll screen.

For example, in a case where the screen of the scroll screen is in an unfolded state, the video recording apparatus may determine an unfolding ratio of the scroll screen (i.e., a first unfolding ratio), and determine the cameras (i.e., the second camera and the third camera) that need to perform image capturing according to the first unfolding ratio.

In one example, the screen recording apparatus may receive a touch input from a user to the first control area of the scroll screen when the scroll screen is unfolded to an unfolding ratio of 50%, enter a split screen recording mode, and then start the second camera and the third camera to perform video recording.

In another example, the screen recording apparatus may receive a touch input from a user to the first control area of the scroll screen when the current single-screen recording mode is adopted and the expansion ratio of the scroll screen is 50%, enter the split-screen recording mode, and then start the second camera and the third camera to perform video recording.

Optionally, the first video recording interface is configured to display a preview image acquired by a second camera in real time, and the second video recording interface is configured to display a preview image acquired by a third camera in real time.

For example, as shown in fig. 3, when the expansion ratio of the reel screen is 50%, a 2-time focal length camera and a main camera are started to respectively shoot the sun and a plurality of trees in the current shooting scene, a video recording interface corresponding to the 2-time focal length camera is displayed in a first sub-display area 31 of the screen of the reel screen, and a video recording interface corresponding to the main camera is displayed in a second sub-display area 32 of the screen, where the video recording interface corresponding to the 2-time focal length camera displays images (including the sun 33, the trees 34 and the right half part of the trees 35) collected by the 2-time focal length camera in real time, and the video recording interface corresponding to the main camera displays images (including the sun 36, the trees 37, the trees 38 and the trees 39) collected by the 2-time focal length camera in real time.

It should be noted that the sun 33 in the upper first subregion 31 and the sun 36 in the lower second subregion 32 in fig. 3 are different preview images obtained by shooting the same shooting object by different cameras, and the trees 35 in the first subregion 31 and the trees 39 in the second subregion 32 are different preview images obtained by shooting the same shooting object by different cameras. Because the field angles of different cameras (namely, the 2-time focal length camera and the main camera) are different, the range of pictures which can be shot by the two cameras is different, namely, the image contents acquired by the two cameras are different.

Therefore, the video recording device respectively displays the video recording interfaces corresponding to the multiple cameras according to the expansion proportion of the scroll screen, so that videos under the fields of view of the multiple cameras can be recorded simultaneously, and the flexibility of video recording is improved.

Further optionally, in this embodiment of the application, after the step a2, the video recording method provided in this embodiment of the application further includes the following steps A3 to a 5:

step A3: the video recording device receives a second input from the user to unwind the spool screen.

Step A4: the video recording device determines a fourth camera based on the expansion ratio of the scroll screen in response to the third input.

Wherein the fourth camera has a different field of view than the first and second cameras.

Step A5: the video recording device controls the fourth camera to record videos, displays a third video recording interface in a third sub-display area of the screen display area of the scroll screen, displays a fourth video recording interface in a fourth sub-display area of the screen display area of the scroll screen, and displays a fifth video recording interface in a fifth sub-display area of the screen display area of the scroll screen.

The third video recording interface is a recording interface of a fourth camera, the fourth video recording interface is a recording interface of the third camera, and one video recording interface corresponds to one camera.

Optionally, the second input is an input of a user to unwind the reel screen, or an input of a user to trigger the video recording apparatus to unwind the reel screen. The second input may be, for example, an input received by the electronic device to manually stretch the scroll screen to unfold the scroll screen, or a user-triggered input received by the video recording apparatus to the scroll screen unfolding control. Further, the trigger input may include any one of: the touch input, the voice input, the gesture input of the user, the telescopic input to the scroll screen, or other feasible inputs are not limited in the embodiments of the present application.

Optionally, the video recording device may determine the expansion ratio of the scroll screen in real time, and if the expansion ratio of the scroll screen is within a preset ratio range, start the corresponding camera to record the video based on the corresponding relationship between the preset expansion ratio and the camera to be started. For example, in the case where the expansion ratio of the scroll screen is greater than or equal to 50% and less than 80%, the 2-time focal length camera and the main camera are simultaneously activated for video recording.

Optionally, the third sub-display area, the fourth sub-display area and the fifth sub-display area may partially overlap or may not completely overlap. Illustratively, the third sub-display area, the fourth sub-display area and the fifth sub-display area may be different display areas of the screen display area, or different split screens in a split screen display state.

For example, referring to fig. 3, the current length of the reel screen is 50%, the video recording device respectively captures the sun and a plurality of trees in the current picture through the 2-fold focal length camera and the main camera, the first sub-display area 31 of the screen display area displays a video recording interface corresponding to the 2-fold focal length camera, a video recording interface corresponding to the main camera is displayed in a second sub-display area 32 of the screen display area, as shown in fig. 4(a), after the user unwinds the scroll screen to 100% of the unwinding ratio, the video recorder starts the wide-angle camera to shoot the scenery in the picture, and displaying a video interface corresponding to the 2-time focal length camera in a third sub-display area 41 of the screen display area, a video recording interface corresponding to the main camera is displayed in a fourth sub-display area 42 of the screen display area, and displaying a video recording interface corresponding to the wide-angle camera in a fifth sub-display area 43 of the screen display area.

So, the video recording device can carry out the video recording at the expansion ratio increase's of spool screen the condition, and newly-increased camera to be adapted to the expansion ratio of screen and record the demonstration of interface, make the preview image under the user can directly perceivedly looking over more camera visual fields. Namely, the user can control the switching among different cameras and the multiple cameras to carry out multi-scene video recording by stretching and adjusting the different proportional sizes of the scroll screen, so that the multi-scene video recording digital zooming function is realized.

Optionally, the video recording device switches the camera corresponding to the video interface after receiving an input that the user triggers the camera corresponding to the video recording interface to be switched.

For example, after receiving a touch input of a user to a switching control in a video recording interface, the video recording apparatus switches a current camera of the video recording interface to another camera, so as to switch picture content in the video recording interface.

For example, referring to fig. 4(a), when the expansion ratio of the scroll screen is 100%, the video recording device starts the wide-angle camera to shoot the scenery in the screen, and displays the video interface corresponding to the 2-fold focal length camera in the third sub-display area 41 of the screen display area, displays the video recording interface corresponding to the main camera in the fourth sub-display area 42 of the screen display area, and displays the video recording interface corresponding to the wide-angle camera in the fifth sub-display area 43 of the screen display area. As shown in fig. 4(b), the user clicks the camera switching control 41a in the third sub-display area 41, the video recording apparatus switches the 2-time focal length camera corresponding to the video recording interface in the third sub-display area 41 to the front camera, and displays the self-portrait image of the user captured by the front camera on the video recording interface in the third sub-display area 41. Therefore, the video recording device records videos of three camera view fields simultaneously to realize a multi-scene video recording function, and after a user selects to switch the cameras, the user can record a long shot while taking a self picture, so that the flexibility of video recording is improved. Therefore, the video recording device can control the switching among different cameras and the method for carrying out multi-scene video recording by a plurality of cameras by stretching and adjusting the proportional size of the scroll screen, and can realize the digital zooming function of the multi-scene video recording. Namely, the user can break through the limitation of single-camera recording by selecting a multi-screen recording mode, realize a multi-scene recording function, and realize the function of recording self-timer and long-range scenes simultaneously.

Further optionally, in the split-screen recording mode, the video recording device may obtain a plurality of videos respectively recorded by the plurality of cameras according to user requirements, and store the video recorded by each camera; or performing video fusion on videos recorded by the multiple cameras according to the positions of the video recording interfaces corresponding to the multiple cameras to obtain fused target videos, and storing the target videos including the multiple video contents recorded by the multiple cameras.

For example, when the video recording apparatus records videos through three cameras at the same time, the video recording apparatus may store the videos recorded by the three cameras respectively, or store a video obtained by synthesizing the videos recorded by the three cameras, or store both of the videos at the same time. Therefore, the user can independently select and store the result of the multi-scene video recording or the result recorded by each camera, and the flexibility of video recording is improved.

Optionally, in this embodiment of the present application, in a case that the recording mode is a single-screen recording mode, before the step 202, the video recording method provided in this embodiment of the present application further includes the following steps B1 and B2:

step B1: the video recording device determines a first camera and a second camera according to the first expansion ratio of the scroll screen.

The field angle of the first camera is smaller than that of the second camera.

Step B2: the video recording device displays a first video recording interface in the screen display area.

The first video recording interface comprises a first preview image.

The first sub-area of the first preview image is an image obtained by fusing a first original image and a second original image, the first original image is an image acquired by a first camera, and the second original image is an image corresponding to the first sub-area in an image acquired by a second camera; a second subregion of the first preview image is a third original image, and the third original image is an image corresponding to the second subregion in the image acquired by the second camera; the third subregion of the first preview image is a fourth original image, and the fourth original image is an image corresponding to the third subregion in the image acquired by the second camera.

It should be noted that, for the description of the first expansion ratio, reference is made to the above, and details are not described here.

Optionally, the video recording device may determine the first camera and the second camera according to the expansion ratio of the scroll screen according to a preset rule between the expansion ratio and the camera. For example, in the case that the current expansion ratio of the scroll screen is within the interval of 50% to 60%, the camera and the second camera are started to record video.

It should be noted that, for the description of the first expansion ratio, refer to the above, and the description is omitted here.

Optionally, the first camera may be a 2-time focal length camera, and the second camera may be a main camera. The shooting visual field of the second camera is larger than that of the first camera, namely the second camera can shoot image frames in a larger range.

Optionally, the first recording interface is configured to display a first preview image corresponding to the first camera and the second camera.

Optionally, the video recording device may perform image registration and fusion processing on a first image (i.e., a first original image) acquired by the first camera and a second image acquired by the second camera to obtain a first preview image.

Illustratively, the first preview image includes a first sub-area, a second sub-area, and a third sub-area. Wherein there is partial overlap or no overlap between the first, second and third sub-regions. Illustratively, the first preview image is updated in real time, that is, the first preview image may be refreshed in real time in the first video recording interface.

Optionally, the video recording device may perform image fusion processing on a first original image acquired by the first camera and a second original image corresponding to the first subregion in the image acquired by the second camera, and display a fused image in the first subregion of the first preview image, where the fused image includes content of the first original image acquired by the first camera.

For example, the video recording device may perform image fusion on an image frame currently acquired by the first camera and an image corresponding to the first sub-region in the image frame currently acquired by the second camera, and display the fused image in the first sub-region to obtain a real-time updated fused image.

It should be noted that the second original image is a part of an image area corresponding to the first sub-area in a frame of image acquired by the second camera; the third original image is a part of image of an image area corresponding to the second subregion in a frame of image acquired by the second camera; the fourth original image is a part of image of the image area corresponding to the third sub-area in the frame of image acquired by the second camera.

For example, as shown in fig. 5, when a shooting scene includes the sun and a plurality of trees, a user unfolds the scroll screen until the unfolding ratio is 50%, and clicks the first control area of the scroll screen to enter a single-screen recording mode, and the video recording device starts the 2-time focal length camera and the main camera to acquire images. The video recording device respectively shoots through the 2-time focal length camera and the main camera, and then carries out image fusion processing on the two images to obtain a preview image 50. Wherein the first subregion 50a of the preview image 50 comprises the image content captured by the 2-focal-length camera (i.e., the sun 51, the trees 52, and the right half of the trees 53), the second subregion 50b of the preview image 50 comprises a portion of the image content captured by the main camera (i.e., the trees 54), and the third subregion 50c of the preview image 50 comprises another portion of the image content captured by the main camera (i.e., the left half of the trees 55).

It should be noted that the left half of the tree 55 in the third subregion 50c on the right side in fig. 5 and the right half of the tree 53 in the first subregion 50a in the middle are different preview images obtained by shooting the same tree with different cameras.
