Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Example 1

Referring to fig. 1, fig. 1 is a flowchart illustrating a video composition method for delayed photography according to an embodiment of the present disclosure. The method is applied to time-lapse photography, the sum of the time spent on photograph shooting and the time spent on video synthesis is taken based on the time spent on the existing time-lapse photography and video synthesis, and manual operation is required for video synthesis. The method triggers video synthesis operation when a photo is shot, and the time interval of the photo shooting is generally between 1s (second) and 1min (minute), while the time required for synthesizing each frame of video is generally in the millisecond level, so that the video synthesis can be finished in the photo shooting process, the video synthesis does not need to spend additional time, the time consumed by delayed shooting is the photo shooting time, the video synthesis time is saved, the effect that the video synthesis can be finished after the photo shooting is finished can be achieved, and the user experience is improved; the method specifically comprises the following steps:

step S100: taking pictures according to preset shooting parameters;

before that, a delay shooting mode can be set for delay shooting, and after a shooting button is clicked, a video synthesis function can be started at the same time.

Step S200: storing the shot pictures in a cache;

step S300: detecting whether a photo exists in the cache;

step S400: and if so, synthesizing the pictures into a video file according to the shooting sequence.

In the implementation process, the shot pictures are stored in the cache, so that the shot pictures are prevented from being lost, for example, when the previous picture is synthesized, a plurality of new pictures are generated, and if the latest picture can be obtained without caching, the previous pictures are lost; on the other hand, the photos are placed in the cache, the operation of video synthesis is triggered by continuously detecting whether the photos exist in the cache, and the videos are synthesized when the photos are detected, so that the step of manual synthesis is omitted, the convenience is improved, the purpose of saving time is achieved, and the problem that the time is wasted because the video synthesis can be carried out only by manually clicking by a user in the conventional method is solved.

Specifically, the preset shooting parameters include a shooting interval and a shooting number, as shown in fig. 2, which is a flowchart for shooting a photo according to the preset shooting parameters, and specifically includes:

step S101: judging whether the current shooting number reaches the shooting number or not;

step S102: if not, continuing shooting until the current shooting number reaches the shooting number.

And starting to shoot pictures according to a preset shooting interval, if every 1min, the shooting quantity is 20, determining whether to continue shooting or not by detecting the current shooting quantity, if not, continuing shooting until the current shooting quantity reaches the shooting quantity, and stopping shooting.

And at the shooting interval, storing the shot pictures into a cache, acquiring the pictures to be synthesized when detecting that the pictures exist in the cache, and synthesizing the pictures to be synthesized.

As shown in fig. 3, which is a flowchart of synthesizing a video file, step S400 may specifically include:

step S401: traversing the timestamps of all the photos in the current cache to determine the shooting sequence of the photos from morning to evening according to the timestamps;

step S402: sequentially analyzing the photos based on the shooting sequence to obtain analysis data;

step S403: converting the analysis data into video data;

step S404: synthesizing a video file based on the video data.

Illustratively, the shooting order of the photos in the current cache can be determined by traversing the timestamps of all the photos in the current cache, taking out the earliest photo to begin parsing, and converting the parsed data, i.e., the image data into video data through decoding, encoding and other processes, for example, video encoding according to video encoding standards such as h.264, h.265 and the like, so as to obtain the video data, and the format of the video data may include, but is not limited to, MP4, MOV, AVI, WMV and the like, and the format of the video data is not limited herein.

As one embodiment, the shooting interval based on the delayed shooting and the video composition time are less than the shooting interval, so that the video data can be formed after the first parsing is completed, an unfinished video file can be generated from the video data, the video data formed after the second parsing and the unfinished video file of the first parsing are composited again, and so on, and when the number of the parses reaches the shooting number, the video data of the last photo and the unfinished video file are composited in a whole to generate the video file.

As another embodiment, the video data may be formed after the first photo is analyzed, the video data may be formed after the second photo is analyzed, and so on, when the number of the analyzed photos reaches the shooting number, the video data of all the photos are synthesized to generate the video file, and the method for synthesizing the video file is not limited herein.

In the process of analyzing the photos, the number of the analyzed photos needs to be determined to ensure that all the photos (the photos with the preset shooting number) are analyzed, so as to avoid omission or loss of the photos, as shown in fig. 4, a flow chart of the determination process of the number of the analyzed photos includes the following specific steps:

step S410: judging whether the current analysis number of the photos reaches the shooting number or not;

step S411: if not, continuously detecting whether the pictures exist in the cache or not until the current analysis number reaches the shooting number.

And judging whether the analysis number reaches the preset shooting number, if not, continuously detecting whether pictures exist in the cache or not, performing video synthesis, and if the analysis number reaches the shooting number, generating a video file, and finishing the whole operation.

Exemplarily, as shown in fig. 5, for the generation flowchart of the MP4 file, a delayed photography mode is set and delayed photography parameters (a photography interval and a photography number) are set so as to enter delayed photography, during which a photography function and a video synthesis function are started, and the photographed pictures are stored in a cache, and at the same time, it is continuously determined whether the photography number reaches a preset photography number, and the photography is completed until the photography number reaches the preset photography number, and the photography may be stopped; and judging whether a picture exists in the cache, if so, taking out the picture with the earliest shooting time for analysis to obtain analysis data, sending the analysis data to an MP4 packaging module for video synthesis, repeatedly judging whether the analysis number reaches the preset shooting number, if not, judging whether the picture exists in the cache again, synthesizing the video until the analysis number reaches the shooting number, completing the video synthesis, and generating an MP4 file.

The method can synthesize the video while taking the picture, saves the video synthesis time, is convenient to use, does not need to manually start the video synthesis operation after the picture is taken by a user, and solves the problem that the video synthesis can be carried out only by manually clicking by the user in the conventional method, so that the time is wasted.
