ABSTRACT:
Frame-to-frame comb filter for separating chrominance and luminance components of composite video signals produce distortions around the periphery of reproduced moving images. The color distortions are corrected by selectively adding the combed luminance signal to the combed chrominance signal during periods of detected motion, and bandpass filtering the combined signal to pass only the chrominance spectrum.
