Abstract

A shooting method, device and unmanned aerial vehicle. The method includes: judging whether the difference between the first exposure value of the current frame determined by the automatic exposure algorithm and the second exposure value of the last frame of time-lapse photography is less than or equal to a preset first threshold; if the first exposure value is different from the first exposure value The degree of difference between the two exposure values ​​is less than or equal to the first threshold, then the third exposure value of the current frame of time-lapse photography is determined according to the second exposure value and the first offset, and the absolute value of the first offset is positively correlated with the degree of difference , and the absolute value of the first offset is smaller than the difference degree. The invention can avoid the problem of brightness flickering in the captured video.

Description

technical field [0001] The invention relates to the technical field of shooting, in particular to a shooting method, device and unmanned aerial vehicle. Background technique [0002] Time-lapse photography is an important function of digital cameras. The principle is to extract a frame in the video stream at a fixed time interval, or obtain a photo frame, and finally combine all the frames after the shooting time set by the user is reached. Compose a video with a fixed frame rate. [0003] In the prior art, the exposure parameters of each frame of time-lapse photography can be determined based on an automatic exposure algorithm (AutoExposure, AE) used to determine the exposure parameters of each frame of ordinary video. Assuming that the exposure value determined by the AE algorithm is BV, and the exposure value of the combination of exposure parameters used in the current time-lapse photography frame is BV', the solution for determining BV' can be BV=BV', and further, it c...
