The information about partial images is outputted for each pixel of an input image and a pattern composed of the information about partial images is obtained. The scaling factor estimation unit 2 uses a pattern composed of the information about partial images outputted from the partial image detection unit 1 to detect an area where a predetermined number of partial images exist, and determines the scaling factor of the input image from information of the area.
