ABSTRACT:
A frame comb filter system having circuitry to minimize motion-induced artifacts in the reproduced image includes a line comb filter to extract a relatively high frequency luminance correction signal from frame comb filtered chrominance signal. This luminance correction signal, however, includes undesirable signal components due to vertical chrominance transitions even in the absence of motion. The system therefore includes circuitry to selectively recombine the high frequency luminance correction signal with frame comb filtered luminance signal only when motion occurs.
