フイルタ。[Claims for Utility Model Registration] Two delay means, each having a delay time corresponding to one horizontal scanning period, are continuously connected to each other, and the input and output signals of each delay means are summed to obtain a luminance signal. A comb filter comprising an adder and a subtracter for obtaining a color signal by taking the difference between the input and output signals of each delay means, the two luminance signals being switched and synthesized by the color signal. .
