Abstract
The present invention relates to video processing, and provides a method for detecting and reducing video flicker. The method for detecting video flicker includes steps of: calculating the line sums of the luminance components of two adjacent frames in a video frame sequence; comparing the line sums of the luminance components of the two adjacent frames, and calculating a flicker component; obtaining the light source flicker frequency according to an assumed k value; determining two different local intervals by the coordinates of a current point of the flicker component according to the light source flicker frequency; and respectively calculating a peak function and a valley function of the flicker component in the two different local intervals; and determining whether there is video flicker caused by the light source in the current frame according to the peak function and the valley function of the flicker component.
