Abstract
A spatial filter applies a modulation transfer function correction process so as to increase a number of bits of input image data. A high-resolution converter converts the image data into output image data having a density higher than a sampling density of the input image data. One of the spatial filter and the resolution converter processes the image data after the other of the spatial filter and the resolution converter has processed the image data A possibility of saturation of an output of the spatial filter is decreased, thereby decreasing generation of moire in a saturation calculation.
