Abstract: A filter is used for separating luminance and color signals from a composite color television signal in which the frequency of the color signal is multiplexed over the high-frequency region of the luminance signal. When a picture is detected with respect to its motion under frame correlation and if that motion is relatively small, the separation of luminance and color signals is performed based on the interframe correlation. If the motion is relatively large, the separation of luminance and color signals is made based on the interfield correlation. The luminance and color signal separation based on the interfield correlation is attained from a correlation with signals in a field spaced forwardly away from the subject field by one field. This is accomplished by selecting a calculation having the highest correlation in calculations for an objective sample point and a plurality of sample points located about the objective sample point.

Abstract: Motion-adaptive chrominance-luminance separation of a composite video signal is accomplished by comb-filtering the video signal on the time axis, bandpass-filtering the video signal on at least one spatial axis selected according to spatial correlation detected in the video signal, and combining the two filtered results in proportion to motion detected in the video signal. Motion is detected in part by obtaining a one-frame difference signal that has been filtered to eliminate chrominance information; here too the filtering is performed on at least one spatial axis selected according to spatial correlation. Selecting the spatial filtering axes according to spatial correlation enables chrominance and luminance to be separated effectively without unnecessary information loss.
