Abstract
Line flicker is detected by comparing luminance values provided by a video signal in vertically successive lines of two temporally successive fields. If there is a step change in adjacent lines, indicative of line flicker, the line flicker is corrected by adaptively delaying or accelerating corresponding lines within the field that experienced the step change.
