TWO-DIMENSIONAL ADAPTATION TYPE LUMINANCE/CHROMINANCE SIGNAL SEPARATION APPARATATUS

A two-dimensional adaptation type luminance/chrominance signal separation apparatus for separating the luminance signal from the chrominance signal in accordance with correlation in a vertical direction includes a coefficient generator for generating a selection signal and mixing coefficients according to correlation of composite video signals, a chrominance signal processor for selectively outputting the chrominance signals filtered from the composite video signals according to the coefficients generated from the coefficient generator whereas the chrominance signals are generated by mixing respective chrominance signal filtered through a predetermined region, and a luminance signal generator for detecting a chrominance signal generated from the chrominance signal processor and a luminance signal generated from the composite video signal.
