    • A picture filter for use in such a case and the like that a luminance signal and a chrominance signal are separated from each other, and particularly to separate precisely a desired video signal from a video signal containing a plurality of signals having different information contents. In order that amplitude levels at adjacent plural points S.sub.i, S.sub.i+1, . . . , and S.sub.j, S.sub.j+1, . . . in a picture are filtering-processed on a plurality of amplitude level axis spaces, there is provided an amplitude correlator 20 to discriminate the amplitude level and polarity to thereby filter-process the same.
