ABSTRACT:
Comb filtered video signals having reduced artifacts are adaptively produced by circuitry including delay elements for providing a plurality of video signals delayed by integral numbers of horizontal line periods, for example, signals delayed 1H, 2H, 1 field, 1 frame, etc. Signals from pairs of these lines of signals are compared by developing the sums of cross differences of samples spanning the sample point to be filtered to produce a signal indicative of the pairs of lines having the highest degree of signal correlation at that instant. The pair of lines exhibiting highest correlation are selectively applied to signal combining circuits to generate comb filtered luminance and chrominance signals in the conventional manner.
