In the embodiment, a fourth input of the user to the video preview image is received, and the display size of the target object in the shooting preview interface is adjusted in response to the fourth input, so that the user can adjust the display size of the target object in the shooting preview interface in real time conveniently.
As a specific embodiment, the video recording method may include the following processes:
(1) the user opens the camera recording function of the mobile phone, selects the smart direct shooting function, and aims the mobile phone at the stage scene as shown in fig. 2, and the display content of the shooting preview interface 11 of the mobile phone includes the whole stage.
(2) Before recording the video, guiding the user to select a proper shooting range. And displaying the field of view (FOV) of all cameras on a shooting preview interface, and manually selecting a proper field of view by a user to record the direct-shot video. As shown in fig. 3, the mobile phone may display at least two shooting range candidate frames 12 on the shooting preview interface 11, and each shooting range candidate frame 12 may correspond to one field angle.
(3) Guiding the user to confirm the video subject, as shown in fig. 4, the mobile phone can intelligently identify several video objects 13 in the preview picture for the user to select, and the user clicks one of the video objects 13, that is, locks the video object 13 as the video subject; alternatively, the user may also manually select the video body, for example, the user may select an object of interest in a frame of the shooting preview interface, and the background may automatically lock the object of interest as the video body.
(4) After the video subject is determined, the user is guided to select a video subject mode of the video subject.
The following three modes may be provided for user selection:
the first mode is as follows: as shown in fig. 5, in the stand-alone display mode, only the video main body remains in the video image;
and a second mode: as shown in fig. 6, the highlight mode performs blurring processing, such as blurring or mosaic processing, on a portion of the video image other than the video main body;
and a third mode: as shown in fig. 7, in the stitching display mode, a video recorded image is stitched with a video image (for example, a video image obtained in the first mode or the second mode) including a video main body, and one side is a panoramic view angle display area 14 to display a video image of an original video; and a direct-shooting visual angle display area 15 for displaying the video image of the video main body.
For example, when an object of interest of a user exists in objects identified by a mobile phone, the user may click the object of interest, the mobile phone locks a video object selected by the user as a video subject, after the video subject is determined, preview images corresponding to three video subject modes of the video subject may be displayed on a shooting preview interface, and the user may click a preview image corresponding to a certain video subject mode, so as to select the video subject mode.
For example, when there is no subject that the user is interested in the objects identified by the mobile phone, the user may manually select a video object, the user may select the object of interest in the preview interface frame, the mobile phone may automatically lock the object of interest as the video subject, after the video subject is determined, preview images corresponding to three video subject modes of the video subject may be displayed in the preview interface frame, and the user may click on the preview image corresponding to a certain video subject mode, thereby selecting the video subject mode.
It should be noted that, in the group performance, when the user wants to watch only the video of a certain performer, the individual display mode or the highlight display mode may be selected, and when the user wants to watch the group and the performance of a single performer at the same time, the mosaic display mode may be selected.
(5) After the user confirms the video main body and selects the video main body mode, the user clicks the video recording control to start recording the video, a camera of the mobile phone can track through a human body, the position of the video main body in a video recording image is calculated, then the direct-shot is locked on the selected video main body, a background cuts a frame with a proper size around the video main body through calculation according to the recording content, the frame serves as the presentation visual angle of the direct-shot video of the video main body, and therefore the direct-shot video of the video main body can be generated.
As shown in fig. 8, the user may also perform two-finger zooming in and out of the direct-shooting viewing angle display area 15 in the shooting preview interface, and perform recording by self-defining adjustment of the display size of the video body.
