Example one

Fig. 3 is a flowchart of a first embodiment of the interval photographing method of the present invention. A method of interval photographing, the method comprising:

s1, in the interval shooting preview process, obtaining and analyzing the initial shooting image to obtain an initial main body image and an initial background image in the initial shooting image;

s2, after the analysis operation of the initial shot image is completed, acquiring a subject image to be selected corresponding to the initial subject image in the interval shooting process;

s3, if the interval shooting is finished, receiving a backtracking instruction in the initial subject image area;

and S4, sequentially synthesizing the main body image to be selected and the initial background image according to the backtracking instruction and the shooting interval to obtain an image to be selected.

In this embodiment, first, in a preview process of interval shooting, an initial shot image is acquired and analyzed to obtain an initial subject image and an initial background image in the initial shot image; then, after the analysis operation of the initial shot image is finished, acquiring a subject image to be selected corresponding to the initial subject image in the interval shooting process; then, if the interval shooting execution is finished, receiving a backtracking instruction in the initial main body image area; and finally, according to the backtracking instruction, sequentially synthesizing the main image to be selected and the initial background image according to the shooting interval to obtain the image to be selected.

Specifically, in the present embodiment, interval shooting is started in the terminal device, and it is understood that interval shooting in the present embodiment is started by a pre-installed camera application of the terminal device, or interval shooting in the present embodiment is started by a third party application installed in the terminal device. In this embodiment, the interval shooting refers to continuously shooting at a preset interval time within a period of time, optionally, in the interval shooting process, only a first shooting start instruction needs to be executed, and the preset interval time can be determined according to this embodiment to automatically perform subsequent shooting, and optionally, in the interval shooting process, a pause or continue instruction input by a user is received and is respectively used for controlling the interval shooting that is not completed yet, so as to realize pause shooting or continue shooting in the shooting process. In this embodiment, an initial captured image is obtained and analyzed to obtain an initial subject image and an initial background image in the initial captured image, where the initial captured image is an initial captured image obtained through previewing image data in the current interval capturing process, where the initial subject image and the initial background image are both included in the initial captured image, it can be understood that a plurality of initial subject images and a plurality of initial background images are obtained through analysis, and the initial subject image and the initial background image of this embodiment are determined through adaptive recognition, or a user's specified instruction is received to determine the initial subject image and the initial background image of this embodiment.

Specifically, in this embodiment, after obtaining an initial subject image and an initial background image in the initial captured image, after completing the analysis operation of the initial captured image, in the interval captured capturing process, a subject image to be selected corresponding to the initial subject image is obtained. In this embodiment, the interval shooting stage is entered from the shooting preview stage, and at this time, the shooting is continuously performed at preset interval time, in the prior art, the complete images obtained by continuously performing the shooting at the preset interval time are all saved so as to be saved by selecting a proper image for the user, however, the prior art may cause the problems of large storage space consumption and large occupation of processing resources. Therefore, in this embodiment, each image in the interval shooting stage is not completely saved, but only the candidate subject image corresponding to the initial subject image is obtained in the interval shooting process, so that the storage requirement is reduced, and the requirement for processing resources is reduced.

Specifically, in this embodiment, after the subject image to be selected corresponding to the initial subject image is obtained, if the interval shooting execution is completed, the backtracking instruction in the initial subject image area is received. Similarly, as described in the above example, after the photographing is continuously performed at the preset interval time, a plurality of images including the initial subject image area are generated, and are cached in the storage device of the terminal device one by one in the photographing process. At this time, a backtracking instruction input by the user is monitored in the initial subject image region, and the backtracking instruction is used to select an image that the user intends to keep from among the plurality of images generated after the photographing is completed continuously at the above-described interval time.

Specifically, in this embodiment, after receiving a backtracking instruction in the initial subject image region, the subject image to be selected and the initial background image are sequentially synthesized at shooting intervals according to the backtracking instruction, so as to obtain an image to be selected. Similarly, as described in the above example, when the user presses the initial subject image area in the touch screen, the multiple images captured at the interval are sequentially displayed, and it can be understood that the multiple images are respectively obtained by synthesizing different initial subject images and the same initial background image, and therefore, in this embodiment, the different initial subject images and the same initial background image can be sequentially synthesized according to the backtracking instruction of the user and the corresponding backtracking sequence.

The method has the advantages that the initial shot image is obtained and analyzed in the interval shooting preview process, so that the initial main body image and the initial background image in the initial shot image are obtained; then, after the analysis operation of the initial shot image is finished, acquiring a subject image to be selected corresponding to the initial subject image in the interval shooting process; then, if the interval shooting execution is finished, receiving a backtracking instruction in the initial main body image area; and finally, according to the backtracking instruction, sequentially synthesizing the main image to be selected and the initial background image according to the shooting interval to obtain the image to be selected. The humanized interval shooting scheme is realized, so that the user can select the image to be stored from a plurality of interval shot images more efficiently, the system execution efficiency is improved, the storage space is saved, and the user experience is enhanced.

In this embodiment, first, after the interval shooting is started, an initial preview image is monitored in real time in the preview process; and then, if the initial preview image is kept stable in a preset range, acquiring the initial shooting image.

Optionally, after the interval shooting is started, in the preview process, the stability of the initial preview image is monitored in real time;

optionally, if the initial preview image is kept stable within a preset range, the initial captured image is obtained, where a corresponding preset range is determined according to different preview objects, for example, when a moving object is captured and the moving object is kept relatively stable, the initial captured image obtaining operation of this embodiment is executed.

The method has the advantages that after the interval shooting is started, the initial preview image is monitored in real time in the previewing process; and then, if the initial preview image is kept stable in a preset range, acquiring the initial shooting image.
