PROBLEM TO BE SOLVED: To obtain an image signal of high definition surely and efficiently. SOLUTION: From each target pixel of an input image signal having any one of a plurality of color components at each pixel position, a cluster tap extracting section 30 extracts a plurality of pixels in the vicinity of the target pixel. A bit reserving section 31 reserves the most significant n bits (n is a positive integer) of each of a plurality of extracted pixels. Based on the most significant n bits of each reserved pixel value, a class sorting section 32 determines a class and based on a class thus determined, an adaptive processing section 33 generates a pixel having a color component at least different from that of the target pixel at the position of the target pixel.
