ABSTRACT:
A luminance (Y) and chrominance (C) signals separating filter includes a movement detecting circuit which partially detects a movement of an image utilizing a correlation between frames; an inter-frame YC separating circuit which performs a separation utilizing the inter-frame correlation when the movement detecting circuit detects a still image, and outputs intra-frame YC separated C signals and intra-frame YC separated Y signals; an intra-frame YC separating circuit which partially detects a correlation between fields or between frames and a correlation in a field when the movement detecting circuit detects a moving image, performs a separation utilizing the correlations, and outputs intra-frame YC separated C signals and intra-frame YC separated Y signals; a C signal mixing circuit which mixes the inter-frame YC separated C signals and the intra-frame YC separated C signals in accordance with an output of the movement detecting circuit and outputs movement adaptive YC separated C signals; and a Y signal mixing circuit which mixes the inter-frame YC separated Y signals and the intra-frame YC separated Y signals in accordance with the output of the movement detecting circuit and outputs movement adaptive YC separated Y signals.
