The first preset actions corresponding to different second video recording modes can be set according to actual needs, which not only facilitates the interaction between the photographer and the subject, but also is more flexible and convenient. Moreover, the person being photographed can switch the video recording mode through the first preset action, and the photographer can switch the video recording mode by inputting on the first screen, and the control methods are flexible and diverse, which can meet the different needs of different users.

In this embodiment of the present invention, the prompt information associated with the second video recording mode has various manners, which are described below with examples.

As one of the preferred specific implementation manners: the prompt information includes a preset multimedia file.

The preset multimedia files may be animations, icons, texts, or small videos, etc. The user can set preset multimedia files associated with different recording modes according to actual needs, which is more flexible and convenient.

Still taking FIG. 2 as an example, the preset multimedia file 21 associated with the start recording mode displayed on the second screen 25 is an animation of slate punching. Still taking FIG. 3 as an example, the preset multimedia file 31 associated with the re-recording mode displayed on the second screen 35 is an unhappy face icon. Still taking FIG. 4 as an example, the preset multimedia file 41 associated with the pause recording mode displayed on the second screen 45 is a pause icon. Still taking FIG. 5 as an example, the preset multimedia file 51 associated with the stop video recording mode displayed on the second screen 55 is a stop icon.

By displaying the preset multimedia files on the second screen, the colors and patterns are more eye-catching, which can better prompt the photographer to pay attention to the change of the recording mode.

As another preferred embodiment, the second recording mode is a close-up recording mode or a switching portrait mode, and the prompt information corresponding to the second recording mode includes a floating frame for selecting a target object.

Taking FIG. 6 as an example, the second video recording mode is a close-up video recording mode, and after receiving the user's pressing input on the close-up button (Close up button) 63 displayed on the first screen 62, it is determined that the video recording mode switching input is received, and the video recording mode The switching input is used to switch the first recording mode to the close-up recording mode, and a floating frame 61 for frame selection of the target object is displayed on the first screen and the second screen.

Taking FIG. 7 as an example, the second recording mode is a character switching mode, and the user's pressing input on the character switching button (Person button) 73 displayed on the first screen 72 is received, and it is determined that the recording mode switching input is received. The switching input is used to switch the first video recording mode to the character switching mode, and a floating frame 71 for frame selection of target objects is displayed on the first screen and the second screen.

By displaying the floating frame on the second screen, the subject in the floating frame can be reminded to pay attention that the camera is about to switch to himself, so that the subject is prepared in advance, which further improves the efficiency and effect of shooting.

In some preferred embodiments of the present invention, step 103 includes: playing the preset multimedia file on the second screen; and switching to the second recording mode after the preset multimedia file is played.

That is to say, after receiving the recording mode switching input, the preset multimedia file associated with the second recording mode is played first, and after the preset multimedia file is played, it is switched to the second recording mode, and the playback of the preset multimedia file takes a certain time. , which can give the subject sufficient time to prepare, and is also conducive to the interaction between the subject and the photographer at the preset playback time of the multimedia file, thereby improving the efficiency and effect of shooting.

Wherein, the playback duration of the preset multimedia file may be determined according to the first preset motion of the subject detected in the image collected by the camera.

Still taking FIG. 2 as an example, if the detected first preset motion is the motion 22 in which the subject lifts one finger and shakes it, the playback duration of the preset multimedia file is 1 second; If two fingers shake left and right, the preset playback time of the multimedia file is 2 seconds.

Still taking FIG. 3 as an example, if the detected first preset motion is the motion 32 of the subject raising two fingers to draw a circle, the preset playing time of the multimedia file is 2 seconds.

The correspondence between the first preset action and the preset playback duration of the multimedia file may be preset according to requirements. Of course, the preset playing duration of the multimedia file may also be a fixed duration (eg, 5 seconds) preset by the user according to actual needs, which is more flexible and convenient.

Preferably, the first recording mode is a waiting-recording mode, and the second recording mode is the starting recording mode. Step 103 includes: playing the preset multimedia file on the second screen, and detecting the camera Whether there is a second preset action of the subject in the captured image; if the second preset action is detected, maintain the mode to be recorded; if the second preset action is not detected and When the preset multimedia file is played, switch to the start recording mode.

That is to say, during the playback of the preset multimedia file, it is necessary to detect whether the subject gives feedback. If the image captured by the camera includes the second preset action of the subject (that is, the subject gives feedback), it means If the person being photographed is not ready, it remains in the recording mode, and does not enter the start recording mode; if the image captured by the camera does not include the second preset action (that is, the person being photographed does not give feedback), it means that the person being photographed has Be prepared and switch to start recording mode when the preset multimedia file has finished playing.

Therefore, the subject can control whether to switch to the start recording mode according to his own state, and it can also avoid the situation of switching to the start recording mode due to a misoperation on the first screen. After the subject sees the prompt information, it can give feedback actions to cancel the switching of the recording mode, which is more flexible and makes the interaction between the photographer and the subject better.

Further, the maintaining in the to-be-recorded mode includes: after maintaining in the to-be-recorded mode for a preset duration, entering the start recording mode.

That is, the first recording mode is the recording-to-be-recorded mode, and if the second preset action is detected, the recording-to-be-recorded mode is maintained for a preset duration before entering the start recording mode. Therefore, sufficient time is given to the subject to prepare, and the shooting efficiency can be further improved.

Wherein, the preset duration is determined according to the second preset action.

For example, receiving a recording mode switching input, the recording mode switching input is used to switch the to-be-recorded mode to the start recording mode, and play the preset multimedia file associated with the start recording mode. In the image, if it is detected that the person being photographed lifts one finger and shakes it left and right, it means that the person being photographed is not ready. After maintaining the recording mode for 1 minute, it will enter the start recording mode; if it is detected that the person being photographed lifts up When two fingers shake left and right, it will remain in the standby recording mode for 2 minutes, and then enter the start recording mode. The corresponding relationship between the second preset action and the preset duration may be preset according to requirements. Of course, the preset duration may also be a fixed duration (eg, 30 seconds) preset by the user according to actual needs, which is more flexible and convenient.

Preferably, the second video recording mode is the re-recording mode or the stop video recording mode, and step 103 includes: stopping video recording in the first video recording mode, and storing the video recorded in the first video recording mode , and play the preset multimedia file on the second screen; after the preset multimedia file is played, switch to the second recording mode.

That is to say, receiving the recording mode switching input of switching the first recording mode to the re-recording mode or stopping the recording mode, stopping the video recording and storing in the first recording mode, can save a more complete and stable video, prevent data If it is lost, it is beneficial for users to edit and process it later.

In some other preferred embodiments of the present invention, the second recording mode is the close-up recording mode, the prompt information corresponding to the second recording mode is displayed on the second screen, and the mode is switched to the The second recording mode includes: determining the target object in the image captured by the camera, displaying the floating frame on the first screen and the second screen where the target object is located; zooming in on the The target object in the floating frame is obtained as an enlarged target object; and the enlarged target object is displayed on the first screen and the second screen.

6 and 8, the photographer presses the close-up button 63 displayed on the first screen 62, the target object in the floating frame 61 is the upper body of the father and the little daughter, and the camera closes up the upper body of the father and the little daughter, and the father and the little daughter are close-up. And the upper body of the little daughter is enlarged to the full screen, as shown in Figure 8.

Further, please refer to Figs. 8, 9 and 10 in combination. On the basis of Fig. 8, the photographer presses the close-up button 92 again. Zoom in on Dad's face to fill the screen, as shown in Figure 10.

Therefore, by displaying the floating frame, the subject in the floating frame can be reminded to pay attention that the camera is about to take a close-up of himself, so that the subject is prepared in advance. It is more flexible and convenient to zoom in on the local details of the photographer, such as zooming in to a certain face, or zooming in to the upper body of a certain subject.

In some other preferred embodiments of the present invention, the second recording mode is the switching portrait mode, the prompt information corresponding to the second recording mode is displayed on the second screen, and the switch to the The second recording mode includes: determining the target object in the image captured by the camera, displaying the floating frame on the first screen and the second screen where the target object is located; zooming in on the For the target object in the floating frame, the enlarged target object is obtained; according to a preset method, the objects currently enlarged and displayed on the first screen and the second screen are switched to the enlarged target object.

Please refer to FIGS. 7 and 11 in conjunction. The photographer presses the character switch button 73 displayed on the first screen 71 to reduce the image of a family of four captured by the camera, and display the reduced image 75 on the first and second screens. , and the center of the image is enlarged and displayed, as shown in Figure 7, the upper body 76 of the son is enlarged, and the floating frame 71 is displayed at the image 75 of a family of four which is displayed in a reduced size, for example: the target object in the frame of the floating frame 71 is the mother , switch the son's upper body 76 currently enlarged and displayed to the mother's upper body 77 , as shown in FIG. 11 .

Among them, the preset methods are various, for example: the upper body of the son is currently enlarged and displayed, the camera is zoomed out first, the image of a family of four is displayed in full screen, and then quickly zoomed in, the upper body of the mother is displayed in full screen; another example: The camera quickly switches from the upper body of the son to the upper body of the mother, and so on, in order from left to right.

In the prior art, when people are photographed, people are switched, and the original intention is not to record the whole crowd into an image. When people are switched, the captured image is first zoomed in and then focused. The shooting process is cumbersome and the images are not connected naturally. There are also positioning requirements. Adjust the problems that affect the beauty of the composition, such as: the person after the switch is not in the center of the captured image, and the user who is photographed does not know when the lens will cut to him, which affects the efficiency and effect of shooting.

In the embodiment of the present invention, in the case of entering the character switching mode, by displaying the floating frame, the subject in the floating frame can be reminded that the camera is about to switch to himself, so that the subject is prepared in advance, and can automatically Switching characters according to the preset method, the image connection is natural and smooth, and the switched characters are located in the center of the image, the composition is more reasonable and more beautiful, and the video effect is better.

Preferably, the determining the target object in the image captured by the camera includes: in the image, determining an initial object; in the case of receiving an adjustment input for adjusting the target object within a preset time, adjusting the target object with the image The object corresponding to the adjustment input is determined as the target object; in the case that the adjustment input of the adjustment target object is not received within a preset time, the initial object is determined as the target object.

Specifically, still taking FIG. 7 as an example, if the preset time is 1 second, the initial object is the upper body of the rightmost person in the captured image (ie, the upper body of the mother). If the adjustment input from the user to adjust the target object is received within 1 second (for example: pressing on the father's chest), the target object is adjusted to the upper body of the father; if the adjustment input is not received within 1 second, the initial The subject is determined to be the target subject, the upper body of the mother. Furthermore, in a preset manner, the son's upper body 76 currently enlarged and displayed on the first screen 72 and the second screen 74 is switched to the enlarged target object.

Still taking FIG. 9 as an example, if the preset time is 3 seconds, the initial object is the face of the person on the far right in the captured image (ie, the face of the father). If within 3 seconds, an adjustment input from the user to adjust the target object is received (for example: pressing on the daughter's face), the target object is adjusted to the daughter's face; if the adjustment input is not received within 3 seconds, The initial object is determined as the target object, that is, Dad's face. Further, close-up of the target object is performed, that is, the enlarged target object is displayed on the first screen and the second screen.

Wherein, the initial object can be determined according to a preset rule, and the preset rule can be set according to the needs of the user, which is more flexible and convenient.

Therefore, the shooting process can be simplified, and it is also convenient for the user to adjust the target object in time, thereby improving the shooting efficiency.

In other preferred embodiments of the present invention, the second video recording mode is a music matching mode, and the prompt information corresponding to the second video recording mode includes a pitcher, a teleprompter and/or a staff.

Taking FIG. 12 as an example, it is necessary to shoot a video of the subject singing, and after receiving the pressing input on the music matching button (beat button) 123 displayed on the first screen 122, the tuner 121 can be displayed on the first screen 122 and the second screen 122. screen 124.

The prompt information associated with the mode includes: displaying the tuner on the second screen; wherein, in the tuner, a section of beat after the beat that matches the music currently collected by the terminal is highlighted.

Still taking FIG. 12 as an example, in the tuner, a segment of beats after the beats that match the music currently collected by the terminal is highlighted, and the closer to the vertical line of the beats, the higher the brightness. It is also possible to zoom in and display a segment of beats after the beats that match the music currently collected by the terminal, and so on. By highlighting, it can remind the subject of the upcoming beat, help the subject to better grasp the beat, and improve the shooting efficiency.

Optionally, the prompt information associated with the music matching mode includes the pitcher; the displaying the prompt information associated with the second video recording mode on the second screen includes: displaying the pitcher on the first screen and the second screen; the video recording method further includes: receiving an adjustment input from a user on the first screen, the adjustment input being used to adjust the playback progress of the tuner; responding to The adjustment input displays adjustment prompt information indicating that the playback progress of the tuner is adjusted on the second screen.

For example, in the song mix scene, the subject needs to sing multiple songs, but each song only sings a few lyrics. The photographer can remind the subject by controlling the playback progress of the pitcher. Still taking FIG. 12 as an example, the subject is about to finish singing the lyrics in song A, and the photographer can slide input 126 on the playback progress bar 125 of the pitcher. , adjust the music progress to song B, and display adjustment prompt information (not shown) indicating that the playing progress of the pitcher is adjusted, such as the song title of song B, on the second screen 124 .

Therefore, the person being photographed can be reminded to pay attention to the adjustment of the progress, and sing, play or perform a tune corresponding to the playing progress, thereby further improving the shooting efficiency.

In some preferred embodiments of the present invention, the first video recording mode is a music matching mode, and in the music matching mode, the second screen displays a pitcher, and the pitcher includes a pitch for identifying the pitch. horizontal line; the second video recording mode is a re-recording mode or a stop video recording mode; the receiving video recording mode switching input includes: calculating the degree of deviation between the pitch of the music collected by the terminal and the pitch of the standard music; In the case that the degree is greater than or equal to the preset deviation threshold, it is determined that the recording mode switching input is received.

That is to say, when recording in the music matching mode, the second screen displays a pitch meter. If the subject is seriously out of tune, it is determined that the recording mode switching input is received, and then the music matching mode is adjusted to the re-recording mode or stop Video mode.
