Document Type and Number:
WIPO Patent Application WO/2017/076050
Kind Code:
A1
Abstract:
An anti-jitter time-lapse photography method and device. The method comprises: recording a video, and periodically and dynamically adjusting the exposure time, the photosensitive speed ISO and the light input of an electronic aperture in a video recording process to obtain multiple frame images that are exposed under different parameters within time periods; synthesizing the frame images that are exposed under different parameters within the time periods, so as to form a frame image corresponding to each time period; and combining the frame images synthesized within the time periods to generate a playing video. Anti-jitter processing can be implemented in the video recording process, and the data processing is simple and efficient; and meanwhile, after the anti-jitter processing, the size of the video image is kept equal to the size of the originally recorded frame image.
