Optionally, after the first electronic device enters a multi-station shooting mode, multi-station shooting information may be broadcast, after the second electronic device starts the multi-station shooting mode, prompt information may be output according to the multi-station shooting information broadcast by the first electronic device, where the prompt information is used to prompt whether to perform multi-station shooting in combination with the first electronic device, and when the second electronic device receives a permission to perform multi-station shooting in combination, the second electronic device establishes a connection with the first electronic device. In the multi-camera shooting mode, the electronic devices connected with each other can share the preview picture acquired by shooting in real time, namely one electronic device can see the shooting pictures of other electronic devices connected with each other. In addition, a plurality of different cameras can be included in one electronic device, and when at least two cameras are started to shoot by one electronic device, the electronic device can also display preview pictures (namely shooting preview pictures) acquired by the different cameras. Wherein, the multi-camera shooting mode can be understood as: and a plurality of cameras jointly shoot the mode.

In this embodiment, before the preview screen is switched to the target preview screen, the at least two cameras may be controlled to perform shooting first, for example, in some embodiments, when the first electronic device receives a shooting command, the at least two cameras are controlled to perform shooting according to the shooting command, where the shooting command may be a shooting command input by a user of the first electronic device, or may be a shooting command sent to the first electronic device when one second electronic device receives a shooting operation performed by the user. In some embodiments, at least two electronic devices may also be directly controlled by the second electronic device to take a photograph.

Optionally, as shown in fig. 2, a first operation control 201 may be displayed in the second preview area, and the user inputs a shooting command by clicking the first operation control 201, so as to control multiple cameras to shoot. Of course, in other embodiments, the shooting command may be input by an operation command such as voice or gesture.

It should be noted that, in the embodiment of the present application, after receiving the shooting command, the multiple cameras may start shooting and recording at the same time, or perform shooting and recording by using cameras that satisfy a certain condition, for example, only perform simultaneous shooting and recording for the camera at the host, or control all the cameras to perform simultaneous shooting and recording, which is not limited further herein.

102, in the process of video shooting, switching a target preview picture for generating a target video based on at least part of candidate preview pictures in N candidate preview pictures, wherein the candidate preview pictures are determined based on picture aesthetic scores in the preview pictures of the first display area, and N is a positive integer;

in the embodiment of the present application, switching the target preview screen for generating the target video from among the candidate preview screens may be understood as determining, as, or as the target preview screen the candidate preview screen. Namely, the target preview screen is changed at different times through the switching command, and the camera corresponding to the target preview screen can be understood as a main camera or a main position. The cameras of the at least two cameras except the main camera can be understood as candidate cameras or candidate airplane position cameras or candidate airplane positions.

Alternatively, the aesthetic screen score of each preview screen may be determined by the first electronic device, and the preview screen that may be a candidate preview screen is determined based on the aesthetic screen score of each preview screen. The electronic devices may determine the aesthetic screen scores of the preview screens acquired by their cameras, determine whether the preview screens acquired by their cameras can be used as candidate preview screens, determine the aesthetic screen scores of the preview screens acquired by their cameras, and transmit the aesthetic screen scores to the first electronic device, and the first electronic device may determine the preview screens that can be used as candidate preview screens based on the aesthetic screen scores of the preview screens.

For example, in some embodiments, a certain preview screen 2 is switched to be in front of a target preview screen, the target preview screen includes the preview screen 1, and after the preview screen 2 is switched to be the target preview screen, the switched target preview screen may be any of the following: comprises a preview picture 1 and a preview picture 2; the target preview screen includes only the preview screen 2.

In some embodiments, before a certain preview screen 2 is switched to a target preview screen, the target preview screen includes a preview screen 1 and a preview screen 3, and after the preview screen 2 is switched to the target preview screen, the switched target preview screen may be any of the following: comprises a preview picture 1, a preview picture 2 and a preview picture 3; includes only the preview screen 2; comprises a preview picture 1 and a preview picture 2; including a preview screen 3 and a preview screen 2.

It should be noted that, in the embodiment of the present application, switching may be performed periodically according to the aesthetic evaluation of the picture at preset time intervals, and one or more candidate pictures may be switched to the target preview picture in one switching process. The candidate screens may also be updated in real time based on the screen aesthetic scores and then switched by the user through a switch command.

And 103, generating the target video by the first electronic equipment based on the target preview picture.

After shooting is completed, a final target video can be obtained by integrating video data recorded in different target preview pictures in different time periods, for example, video data shot by each camera can be integrated by each electronic device to obtain a target video. The target video may also be obtained by integrating only the video data shot by each camera by the first electronic device, and optionally, the first electronic device may further distribute the shot target video to the second electronic device.

Optionally, in some embodiments, the video data of all the cameras may be generated in the first electronic device, the video data of all the cameras may also be generated in each electronic device, and the video data shot by each electronic device may also be generated by each electronic device, which is not limited herein.

Optionally, in some embodiments, the method further comprises:

and determining the preview picture with the picture aesthetics score meeting a preset condition as the candidate preview picture, wherein the preset condition is used for representing that the corresponding preview picture can be used as a shooting picture.

It should be understood that, for the light of the picture, when the shooting angle has more suitable light, more controllable exposure can be realized, the light of the picture is better, and a better video effect can be obtained;

aiming at the integrity of the shot object, when the integrity of the shot object is better, a more prominent main body can be provided, so that a better video effect can be obtained.

Aiming at the facial expression characteristics, when the shot people have richer expressions, the shot people have richer leading roles, and a better video effect can be obtained;

aiming at the depth of field of the picture, the shooting space has more variable depth of field, so that more mirrors are moved, and a better video effect can be obtained.

Therefore, in the embodiment of the present application, the preview screen is scored according to the above target parameters, and the preview screen of which the screen aesthetic score meets the preset condition is determined as the candidate preview screen. Therefore, the finally shot target video has better video effect.

Optionally, in some embodiments, the at least two cameras include a camera of a second electronic device, and the method further includes:

under the condition that target electronic equipment determines that the image aesthetic score of a preview image corresponding to the target electronic equipment meets a preset condition, the first electronic equipment receives a switching request sent by the target electronic equipment, wherein the preset condition is used for representing that the corresponding preview image can be used as a shooting image, and the target electronic equipment is the second electronic equipment;

and the first electronic equipment determines the preview picture corresponding to the target electronic equipment as the candidate preview picture.

In the embodiment of the application, each second electronic device can determine the image aesthetic score of the preview image acquired by the camera of the second electronic device, and determine whether the preview image acquired by the camera of the second electronic device meets the preset condition, so that the second electronic device actively sends the switching request to the first electronic device. In this way, each electronic device is used for calculating the preview picture shot by each electronic device, so that the hardware requirement on the first electronic device can be reduced, and the calculation efficiency of the aesthetic score of the picture can be improved. Furthermore, the electronic devices which carry out multi-camera shooting can share the aesthetic scores of the pictures which are obtained by respective calculation.

It should be noted that the preset condition may be set according to actual needs, for example, in some embodiments, the preset condition includes at least one of the following:

is greater than a preset value;

and the aesthetic scores of the first M pictures are arranged from large to small, wherein M is a positive integer.

Before switching the preview screen to the target preview screen by the switch command, the initial target preview screen for generating the target video may be determined by the first switch command without setting the default target preview screen. In the embodiment of the present application, in order to improve the shooting efficiency, a default target preview screen may be set before the preview screen is switched to the target preview screen by the switch command. For example, before switching the target preview screen for generating the target video based on at least part of the N candidate preview screens, the method further includes:

the first electronic equipment determines a preview picture shot by an initial main camera of the first electronic equipment in the at least two cameras as an initial target preview picture;

and the first electronic equipment displays the initial target preview picture in a second display area of the first electronic equipment.

In the embodiment of the present application, the initial main camera may be one camera or a plurality of cameras, which is not further limited herein, and in the following embodiments, the initial main camera is taken as one camera, and the cameras of at least two cameras except the initial main camera are taken as the cameras of the second electronic device for example.

It should be understood that the at least two cameras may include a current main camera and a candidate camera, the current main camera may be understood as a camera corresponding to the current target preview picture, and the remaining cameras may be understood as candidate cameras, or referred to as candidate airplane position cameras or candidate airplane positions. In the embodiment of the present application, the switching of the candidate preview screen to the target preview screen may be understood as switching a candidate camera corresponding to the candidate screen to the main camera. Alternatively, the number of the main cameras can be kept constant, and can be increased or decreased. For example, in some embodiments, where the number of primary cameras is fixed to N (N equals the number of initial primary cameras, e.g., 1), the initial primary cameras may be switched to candidate cameras. For another example, in some embodiments, a change may occur, such as where the number of primary cameras may be increased from N (N being equal to the number of initial primary cameras, e.g., 1) to N + M, the initial primary cameras may remain and not be switched to candidate cameras. At this time, after the candidate camera is switched to the main camera, the main camera may include the initial main camera and the switched main camera.

It should be noted that the second electronic device may include a first preview area and a second preview area, where the first display area of the second electronic device is used to display the preview screen acquired by the at least two cameras, and the second preview area of the second electronic device is used to display the preview screen acquired by the camera of the own station (i.e., the second electronic device). The first display area may be a main preview window. The preview screen corresponding to the host position may be marked and displayed in the second display area of each electronic device (as shown in fig. 2 and 3, the first electronic device may mark and display the host position in a form of adding a frame), for example, in a form of enlarging the display area, adding a background, adding a frame, and/or fixing the frame at the head. In addition, in the second preview area of each electronic device, the preview screen corresponding to the own station may be marked and displayed, for example, by increasing the display area, adding a background, or adding a frame (as shown in fig. 4, the second electronic device may mark and display the own station by adding a frame). The display form of the mark of the host bit is different from that of the mark of the local bit, and the specific marking mode is not further limited herein.

Alternatively, the preview screen may be displayed in the form of a thumbnail in the first display area.

Optionally, in some embodiments, the candidate screen may also be actively controlled to be switched to the target preview screen through a switch command, and a user may input the switch command through voice, gesture, touch, or the like. . It should be understood that the user may perform one or more times of inputting a switch command, and each time of the switch command may control at least one candidate preview screen to be switched to the target preview screen; or after receiving a switching command input by a user, switching the at least two candidate preview screens to the target preview screen according to a preset rule, where the preset rule may include: and switching according to a preset switching sequence, and switching the duration of a certain camera to the main camera (namely, the duration of a certain candidate picture as or switching to the target preview picture). The time length of switching different cameras into the main camera can be the same or different.

For example, in some embodiments, the switching the target preview screen for generating the target video based on at least some of the N candidate preview screens includes:

under the condition that the first electronic equipment receives a first command aiming at a first preview screen, the first electronic equipment switches the first preview screen into the target preview screen;

the first preview picture is a candidate preview picture in the N candidate preview pictures, the first preview picture includes preview pictures except a second preview picture in the preview pictures acquired by the at least two cameras, and the second preview picture is a target preview picture before switching based on the first command.

In the embodiment of the present application, as shown in fig. 2, after receiving a shooting command, video shooting is started, and at this time, the second display area of the first electronic device displays a preview screen of the first electronic device, that is, an initial target preview screen. When receiving the first command for the preview screen 2 (i.e., the first preview screen), the preview screen 2 may be switched to the target preview screen, as shown in fig. 3. When the first command for preview screen image 3 is received again at this time, preview screen image 2 is first canceled as a target preview screen image, and preview screen image 3 is switched to the target preview screen image. Of course, in other embodiments, the setting of the preview screen 1 as the target preview screen may be cancelled, and then the preview screen 3 may be switched to the target preview screen, for example, if the first switching command is associated with the preview screen 1 (for example, if the first command is a slide operation command and the end point of the slide operation is the preview screen 1), the setting of the preview screen 1 as the target preview screen may be cancelled, and then the preview screen 3 may be switched to the target preview screen. Alternatively, in some embodiments, the setting of the preview screen 1 and the preview screen 2 as the target preview screen may also be cancelled, and then the preview screen 3 may be switched to the target preview screen, for example, if the current first command is used to control recording in the form of a single picture for the preview screen 3, then the setting of the preview screen 1 and the preview screen 2 as the target preview screen may be cancelled, and then the preview screen 3 may be switched to the target preview screen.

It should be noted that the numerical values in the preview images in fig. 2 to 4, 5A to 5C, and 6A to 6C may represent the corresponding preview images, for example, the numerical value 1 in the preview image 1 represents the preview image of the first electronic device, the numerical value 2 in the preview image 2 represents the preview image of one second electronic device, and the numerical value in the preview image 3 represents the preview image of another second electronic device. Since the switching is actively performed by the user, the pertinence of switching, determining, setting, or being the target preview screen from the candidate preview screen can be improved.

Optionally, in some embodiments, after the first electronic device receives a first command for a first preview screen and switches the first preview screen to the target preview screen, the method further includes:

the first electronic equipment displays the switched target preview picture in a second display area of the first electronic equipment according to a target display mode;

wherein the target display mode comprises any one of:

displaying a switched target preview picture in a single picture form, wherein the switched target preview picture is the first preview picture;

displaying a switched target preview picture according to a split screen mode, wherein the switched target preview picture comprises the first preview picture and at least part of the target preview picture before switching;

and displaying the switched target preview picture according to a picture-in-picture mode, wherein the switched target preview picture comprises the first preview picture and at least part of the target preview picture before switching.

It should be understood that in some embodiments, the target preview screen before switching may be one target preview screen displayed in a single-picture form, or may be at least two preview screens displayed in a split screen or picture-in-picture form. Under the condition that the target display mode is that the switched target preview picture is displayed in a split screen mode or in a picture-in-picture mode, if the target preview picture before switching is a target preview picture displayed in a single picture mode, the switched target preview picture comprises the target preview picture before switching and a first preview picture, and the target preview picture before switching and the first preview picture are displayed in the split screen mode or in the picture-in-picture mode; if the target preview picture before switching is at least two preview pictures displayed according to split screen or picture-in-picture, the switched target preview picture comprises a part of the target preview picture before switching and a first preview picture, and the part of the target preview picture before switching and the first preview picture are displayed according to a split screen mode or a picture-in-picture mode.

In the embodiment of the present application, the target display mode may be a preset mode, or a display mode determined based on the first command. The video picture effect after the camera is switched is displayed through the second display area, so that the experience effect of a user is improved.

The target preview screen before switching may include a preview screen acquired by the initial main camera of the first electronic device, or may not include the preview screen acquired by the initial main camera of the first electronic device. For example, in some embodiments, the pre-switch target preview screen includes a preview screen acquired by an initial main camera of the first electronic device of the at least two cameras.

In the embodiment of the application, under the condition that the switched target preview picture is displayed in a picture-in-picture or split-screen mode, the target preview picture before switching comprises the preview picture obtained by the initial main camera, which can be understood as that the recording process of the preview picture obtained by the initial main camera of the first electronic device is always maintained, and other switched target preview pictures are taken as special effect scenes for video recording, so that the complexity of video recording is simplified. Under the condition that the switched target preview picture is displayed in a single-picture mode, the target preview picture before switching comprises the preview picture acquired by the initial main camera, and the switching can be realized every time the preview picture acquired by the initial main camera is taken as the target preview picture, so that the influence of the video shooting effect caused by excessive switching is limited.

Optionally, in some embodiments, before the second display area of the first electronic device displays the switched target preview screen in the target display manner, the method further includes:

and the first electronic equipment determines the target display mode based on the input mode of the first command.

Optionally, the input form of the first command may be set according to actual needs, for example, in some embodiments, the first command is a sliding operation instruction, the starting point of the sliding operation instruction is the first preview screen, and the end point of the sliding operation instruction is associated with the target display mode.

In the embodiment of the present application, the target display modes corresponding to different sliding modes are different, and a picture before switching is taken as a preview picture acquired by an initial main camera as an example for explanation. For example, as shown in fig. 5A, if the initial main camera slides upwards, the preview screen acquired by the initial main camera is correspondingly switched to the first preview screen in a single-picture manner, and a specific display effect is shown in fig. 6A; as shown in fig. 5B, if the first preview image and the preview image acquired by the initial main camera are displayed in a split-screen manner and the sliding distance to the second display area is short, the specific display effect is shown in fig. 6B; as shown in fig. 5C, if the second display region is slid for a long distance, the preview screen acquired by the initial main camera and the first preview screen are displayed in a picture-in-picture manner, and a specific display effect is shown in fig. 6C.

Fig. 6A is a diagram showing a single-frame display of the switched target preview screen, fig. 6B is a diagram showing a split-screen display of the switched target preview screen, and fig. 6C is a diagram showing a picture-in-picture display of the switched target preview screen. In this embodiment, the first preview screen may be displayed in a form of a window in a partial display area of the preview screen acquired by the initial main camera, and in other implementations, the preview screen acquired by the initial main camera may be displayed in a form of a window in a partial display area of the first preview screen.

According to the method and the device, the first command is associated with the target display mode, so that different picture display effects can be set based on different operations, and the flexibility of the operation is improved.

Optionally, in some embodiments, the method further comprises:

and the first electronic equipment displays a target identifier on the candidate preview screen, wherein the target identifier is used for representing that the candidate preview screen requests to be switched into the target preview screen.

As shown in fig. 5A to 5C, when the preview screen 3 is determined to be a candidate screen, a target identifier 501 may be displayed on the preview screen 3 to prompt the user that the preview screen suggests switching to a target preview screen. This may improve the convenience of the handover. Further, in order to better remind the user of the first electronic device, when it is determined that a new candidate preview screen exists, the enhanced prompt may be performed in a shaking manner.

It should be noted that, for example, in some embodiments, the generating the target video based on the target preview screen includes:

video recording is carried out on the target preview picture according to a preset rule to obtain the target video;

in the embodiment of the application, the target preview picture for generating the target video is switched, so that the target preview picture determined in the time period can be recorded in different time periods to obtain the video picture corresponding to the time period. For example, in one embodiment, the process of recording includes at least one of:

recording the target preview picture in a single picture form in a time period in which the target preview picture only includes one preview picture, wherein the picture display effect is shown in fig. 7A;

recording the target preview picture according to a split screen mode in a time period when the target preview picture comprises at least two preview pictures and the target display mode is that the switched target preview picture is displayed according to the split screen mode, wherein the picture display effect is as shown in fig. 7B;

in a time period in which the target preview picture includes at least two preview pictures and the target display mode is that the switched target preview picture is displayed in a picture-in-picture mode, the target preview picture is recorded in the picture-in-picture mode, and a picture display effect is as shown in fig. 7C.

Note that, at a different time node, a different preview screen may be switched to a target preview screen, and the effect of the corresponding generated target video is as shown in fig. 8. Assuming that the preview screen 1 is a preview screen corresponding to the initial main camera, in fig. 8, the time periods 1, 3, and 6 can be understood as video clips obtained by recording the preview screen 1 in a single-frame form; in the time period 2, the video segment obtained by recording the preview picture 3 in a single picture mode can be understood, or the video segment obtained by recording the preview pictures 1 and 3 in a picture-in-picture or split screen mode can be understood; in the time period 4, the video segment obtained by recording the preview picture 4 in a single picture mode can be understood, or the video segment obtained by recording the preview pictures 1 and 4 in a picture-in-picture or split screen mode can be understood; in the time period 5, the video clip obtained by recording the preview picture 2 in a single-picture form or the video clips obtained by recording the preview pictures 1 and 2 in a picture-in-picture or split screen form can be understood; the time period 7 may be understood as a video clip obtained by recording the preview screen 3 in a single picture form, or may be understood as a video clip obtained by recording the preview screens 1 and 3 in a picture-in-picture or split screen form.

It should be understood that the video recording may be performed based on the video data displayed in the second display area of the first electronic device at the time of video recording, and the recorded video data may be determined as the target video directly after the video recording is finished.
