Abstract:
A method for suppressing cross-coloration in a video display device includes receiving high-frequency components of luminance signals corresponding to scanlines of an image frame, determining luminance transitions according to the high-frequency components of the luminance signals, and adjusting chrominance signals of the scanlines according to the luminance transitions.
