Abstract
An image processing method converts an N-value image into an M-value image (N<M). The method obtains an appearance frequency distribution of M-value image data corresponding to a predetermined N-value pattern around an objective pixel of N-value image data, to which an M-value image (M<N) is converted, for each of N-value patterns different from each other. The method then estimates M-value image data corresponding to a given N-value image on the basis of the appearance frequency distribution.
