ABSTRACT:
A motion adaptive recursive filter is modified to separate luminance or chrominance signal from composite video. The filter proportions and sums current and frame delayed signal recursively to provide signal-to-noise enhanced luminance signal with the chrominance component reduced to a steady state residual value the first frame after motion ceases. Current composite video signal is appropriately scaled and combined with the signal-to-noise enhanced signal to cancel the residual chrominance component therein.
