The present invention relates to a filter 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 fields spaced forwardly and rearwardly 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 sæmple point. Such a correlation is determined by checking the correlation of image signals in the set of sample points which are spaced apart from one another by one frame and located around the objective sample point.
