Abstract
Frame comb filters effectively separate the chrominance and luminance components of composite video signal but produce undesirable image distortion when interframe motion occurs. Luminance cross components introduced into the comb filtered chrominance signal component during interframe motion intervals contribute to the image distortion. The luminance cross components are eliminated from the comb filtered chrominance signal by successively filtering the chrominance signal with a chrominance bandpass filter and an interline chrominance comb filter.
