A difference (43) between the output of a k-signal non-linear type low-pass filter (8g) and the output of an h-signal non-linear low-pass filter (8r) is added (44) to the value of an h-th pixel signal (h(i,j)) at a noted pixel position, to determine a k-th pixel signal (k(i,j)) at a noted pixel position. At a portion having no correlation of color signals, too, it is possible to perform a pixel interpolation of high precision and a pixel interpolation hard to receive the influences of noises. ® KIPO & WIPO 2007
