Title:
RECURRENT TYPE FILTER SYSTEM
Document Type and Number:
Japanese Patent JPS61224609
Kind Code:
A
Abstract:
A motion adaptive recursive filter is modified to separate luminance or chrominance signal from composite video. The filter proportions and sums (18) current (10) and frame delayed (30) 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 (22) and combined (24) with the signal-to-noise enhanced signal (B) to cancel the residual chrominance component therein.
