It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a flowchart illustrating steps of a shooting method provided in an embodiment of the present application is shown, where the shooting method is applied to an electronic device including a rotatable camera, and the method may include steps S100 to S600.
In the embodiment of the application, the shooting method is applied to the electronic equipment with the display screen and the rotatable camera. The electronic equipment is provided with a rotatable camera so as to enable a static shooting object to operate relative to the camera by controlling the camera to rotate, so that the motion track of the shooting object is shot, and the electronic equipment is provided with a display screen so as to determine the shooting object and the shooting track and display the shot image. Optionally, the electronic device may be a mobile phone, a tablet computer, a camera, or the like.
Step S100, receiving a first input of the preview image by a user.
In step S100, the first input is a confirmation input for the photographic subject and the photographic trajectory, and may specifically include a selection operation of the photographic subject by the user in the preview image of the photographic scene, and further include a selection operation of the photographic trajectory, such as a click, a cursor lock, a circle selection, and the like.
And step S200, responding to the first input, and determining a shooting object and a shooting track.
In the above step S200, the shooting target refers to a subject object to be shot, and is preferably a stationary object in the embodiment of the present application; the shooting track is a position change path which a user wants to shoot a subject to present in a shot image. Since the first input is a confirmation input for the photographic subject and the photographic track, the first input includes information such as indication information of the photographic subject, a specific movement route presented by the photographic subject in the photographic image, and the like, and thus, when the first input of the user is received, it is described that the photographic subject and the photographic track need to be locked, and thus the subject corresponding to the first input is determined as the photographic subject, and the photographic track for the photographic subject can be determined.
And step S300, carrying out focusing shooting on the shot object to obtain a first image.
In step S300, the camera is used to focus and shoot the subject determined in step S200, and a first image that can clearly display the subject is obtained, so as to be used as a background image of the final shot target image.
In practical applications, the step S300 may be executed again when a third input that the user determines to start shooting is received.
And S400, controlling the camera to rotate according to the shooting track, and simultaneously carrying out long exposure shooting on the shot object to obtain a second image.
In the step S400, since the camera is a rotatable camera, the camera can be controlled to rotate according to the shooting track, so that the position of the shooting object in the shooting picture changes along the shooting track; if the camera is controlled to shoot the shot object with long exposure, the image of the shot object can be made to appear at a plurality of different positions in the shot second image, and the different positions are distributed along the shooting track, so that the effect that the shot object moves continuously is presented.
And step S500, extracting a motion trail graph of the shooting object from the second image.
In the step S500, since the photographic subject and the photographic track are already determined, specific areas of the photographic subject at different positions in the second image can be determined, and then a motion track map of a picture only including the photographic subject can be extracted from the second image, that is, all other areas of the second image except the area where the photographic subject appears are removed; the size of the picture of the moving track graph is the same as the size of the shooting picture of the camera, and then the size of the moving track graph is the same as the size of the second image and the size of the first image.
And S600, synthesizing the motion trail graph and the first image to obtain a target image.
In the step S600, a picture synthesis technique is used to synthesize the trajectory graph extracted in the step S500 to the first image captured in the step S300, wherein the trajectory graph is a picture area only including the object, and the trajectory graph has the same size as the first image, so that the trajectory graph can be accurately superimposed on the first image, thereby displaying the motion trajectory of the object on the target image, and using the first image to clearly display the characteristics of the object.
According to the shooting method provided by the embodiment of the application, a shooting object and a shooting track are determined by receiving first input of a user on a preview image; focusing shooting is carried out on a shot object to obtain a first image; then controlling the camera to rotate according to the shooting track and simultaneously carrying out long exposure shooting on the shot object to obtain a second image; and then extracting a motion trail diagram of the shooting object from the second image, and synthesizing the motion trail diagram into the first image so as to generate a target image. In the shooting mode, the electronic equipment firstly focuses and shoots the shot object, then obtains the motion trail diagram of the shot object by controlling the camera to rotate and carrying out long exposure shooting on the shot object, and then automatically synthesizes the motion trail diagram with the first image obtained by focusing and shooting, thereby quickly shooting and obtaining the special effect diagram which has a clear shot object and the motion trail of the shot object.

Therefore, in step S401, after the shooting object and the shooting path are determined, the pan/tilt head is controlled to rotate according to the shooting track to drive the camera to rotate according to the shooting track, and the camera is started to perform long exposure shooting on the shooting object, so that a plurality of different positions of the image of the shooting object appearing in the image can be obtained through shooting, and the plurality of different positions are distributed along the shooting track.
In practical application, the shooting interval and the rotational speed of the holder of long exposure shooting can be adjusted according to actual needs.

Step S501, sequentially acquiring each screen region including the photographic object from the second image along the photographic trajectory of the photographic object obtained by photographing in the second image.
In step S501, since the second image is an image obtained by rotating the camera according to the shooting track to perform long exposure shooting, the second image includes a plurality of frame regions of the shooting object, and according to the determined frame region of the shooting object, each frame region shot during the long exposure shooting of the shooting object can be extracted from the second image along the shooting track.
And step S502, determining each picture area as a motion trail graph of the shooting object.

Optionally, in an implementation manner, the shooting method provided in the embodiment of the present invention further includes steps S503 to S504 before step S600.
And S503, receiving a second input of the user to the motion trail diagram.
