The circuit includes a low pass filter(10) for abstracting horizontal luminance signal component(Ya) from image signal(Y+C), a band pass filter(30) for abstracting horizontal chromaticity signal component(Ca) from image signal(Y+C), a line com-filter(25) for abstracting horizontal luminance signal component(Yb,Yc) and horizontal chromaticity signal component(Cb,Cc), a frame com-filter(45) for abstracting a time direction luminance signal component(Yd,Ye) and chromaticity signal component(Cd,Ce), a median filter(24) for generating a luminance signal(Yo), and a median filter(44) for generating chromaticity signal(Co).
