Abstract
A multi-exposure control method includes: acquiring an HDR composite image of the current round composited by the image sensor, the HDR composite image acquired by performing HDR compositing on multiple captured images with different exposures output by the image sensor in the current round, and the multiple captured images with different exposures acquired by performing multi-exposure control on the image sensor using multiple exposure values of the current round; performing linear splitting processing on the HDR composite image of the current round based on the multiple exposure values of the current round to acquire multiple linear splitting images; determining a corresponding exposure value based on exposure statistics of each linear splitting images to acquire multiple exposure values of the next round; and performing multi-exposure control on the image sensor by using the multiple exposure values of the next round to acquire an HDR composite image of the next round.
