Summary:내용없음 A luminance and chrominance signal separator includes linear and non-linear type vertical comb filters (6, 5) to which a digital composite video signal comprising the luminance and chrominance signal is supplied. The linear and the non-linear type vertical comb filters (6, 5) are selectively used in response to the result of detection of correlation between successive vertical lines of the digital composite video signal so that both of colour smear and aliasing noise are eliminated. If necessary, linear and non-linear type horizontal filters (11, 10) are further provided, one of which is selectively used in response to the result of detection of correlation between successive picture elements of the digital composite video signal, so that cross-colour component can be eliminated.
