ABSTRACT:
A frame comb filter system includes circuitry for reducing motion induced artifacts in reproduced images. Frame comb filtered chrominance signal is line comb filtered to extract motion induced luminance cross components therein. The luminance cross components are added to frame comb filtered luminance signal to reduce motion induced luminance signal errors. The corrected luminance signal is then subtracted from composite video signal to produce the chrominance component of composite video.
