Abstract
A method and system for cross color elimination is disclosed in processing of a component video signal comprising component luminance and chrominance information. Aspects of the exemplary embodiments include using separated luminance and chrominance information for each pixel in a current frame, getting absolute distance values between C=a current frame pixel color, P=a previous frame pixel color, H=a high frequency color of the previous frame, and O=a center of a color space; comparing each absolute distance value with a predetermined threshold, wherein if any of the absolute distance values exceed the predetermined threshold, then the pixel is a cross color pixel; and for each cross color pixel, replacing a current frame pixel color with a high frequency average pixel color.
