In some embodiments of the present application, the preset condition includes any one of: the gesture of the target object is in the preset gesture, and the duration of the target object in the static state reaches the preset duration.
In the embodiment of the application, a user can select different modes to control the electronic equipment to automatically shoot the first image comprising the target object in the video recording process.
The method comprises the steps that when a target object is kept in a static state for a preset time, electronic equipment is controlled to automatically shoot the target object, so that a first image is obtained.
Specifically, in the process of recording a video, when the electronic device detects that the attitude change amplitude of the target object in the continuous multi-frame video frames is smaller than the preset amplitude, it can be determined that the target object is in a state of stopping motion for the preset duration. It should be noted that the number of detected video frames corresponds to the preset duration, that is, all video frames within the preset duration.
Exemplarily, when a user needs to record a self-timer video through a mobile phone, the user enters a shooting view angle of the mobile phone after the mobile phone is placed at a fixed position. The mobile phone starts to record the self-timer video, continuously detects the motion state of a user (a target object), at the moment, the user can put out the motion which the user wants to shoot, maintains the motion for a preset time, and automatically starts to shoot after the mobile phone detects that the target object stops moving and reaches the preset time.
Before the video recording starts, a user sets a preset posture according to actual requirements. In the process of recording the video, the electronic equipment shoots a first image when detecting that a target object in the video is in a preset posture.
Specifically, in the process of recording a video, the electronic equipment detects the image content of a video image, and automatically shoots a first image of a target object when the posture of the target object in the image content is consistent with a preset posture set in advance. It should be noted that the preset posture includes posture information and error information, so that even if a certain error exists between the actual posture of the target object and the preset posture, the target object can be identified and automatically photographed, and the identification rate and the photographing success rate are improved.
In the embodiment of the application, the motion state of the target object can be detected in the process of recording the video through the electronic equipment, and the target object is automatically shot under the condition that the time length when the posture of the target object is in the preset posture or the time length when the target object is in the static state reaches the preset time length, so that the purpose of taking the picture in the video recording process without user operation is achieved, and the convenience of taking the picture in the video recording process of a user is improved.
In some embodiments of the present application, prior to recording the video, the video generation method further comprises: receiving a fifth input of the parameter setting window from the user under the condition that the parameter setting window is displayed; in response to a fifth input, determining shooting parameters; wherein the shooting parameters include at least one of: shooting parameters of images and shooting parameters of videos.
In the embodiment of the application, before the electronic device starts to record the video, the electronic device displays the parameter setting window. The user can set the shooting parameters of the subsequent video recording of the electronic equipment by executing the fifth input to the parameter setting window, and can also set the image shooting parameters of the image shot in the video recording process.
After the shooting parameters are set, the electronic equipment records a first video according to the shooting parameters of the video in the process of recording the video, and shoots a first image according to the shooting parameters of the image.
The shooting parameters of the video include at least one of: the video recording special effect, the video recording visual angle and the video recording frame rate.
The shooting parameters of the image include at least one of: special image shooting effect, shooting visual angle and image shooting size.
Fig. 6 shows a schematic view of a shooting parameter setting interface provided in an embodiment of the present application, and as shown in fig. 6, a parameter setting window 602 in a shooting parameter setting interface 600 of an electronic device displays a plurality of controls 604 corresponding to an image shooting special effect that can be added, and a user sequentially clicks the controls 604 according to actual needs. The electronic device sequentially displays a special effect identifier 606 corresponding to the added image capturing special effects in a parameter setting window 602 in the capturing parameter setting interface 600.
It should be noted that, in the case where the image special effect is set to be completed before the start of shooting, when the electronic device records the first video, the image special effects are sequentially set to the plurality of first images obtained by shooting according to the order of adding the special effects. For example: the user adds the sticker special effect, the fuzzy special effect, the no special effect and the automatic zooming special effect in sequence, the electronic equipment sequentially configures the sticker special effect, the fuzzy special effect, the no special effect and the automatic zooming special effect to the shooting to obtain a first image, a second image, a third image and a fourth image in the process of recording the first video, and the special effects are not configured to the images obtained through the shooting later.
In the embodiment of the application, the user can set the shooting parameters of the video and the shooting parameters of the image in advance before the electronic equipment starts to record the video, the setting is not needed in the video recording process, the operation steps of recording the video by the user are simplified, and the operation convenience is improved.
