ABSTRACT:
A frame-to-frame comb filter system which reduces motion induced artifacts in the comb filtered luminance signal includes line comb filter circuitry for extracting luminance cross components from the comb filtered chrominance signal and reinserting them into the comb filtered luminance signal and a line comb filter in the luminance path following reinsertion of the luminance cross components to reject motion induced chrominance cross components occurring in the comb filtered luminance signal. The latter line comb filter is switched into the system during periods of interframe image motion.
