Abstract
The present disclosure provides a method and device for correcting video flicker. The method comprises: performing statistics on grayscale values of a previous frame of video image to obtain a histogram of the grayscale values of the previous frame of video image; determining correction weights for correcting grayscale values of a next frame of video image according to the histogram; and correcting the grayscale values of the next frame of video image according to the correction weights.
