Abstract

An image processing apparatus includes a conversion unit configured to convert image data corresponding to a pixel of interest in an image into color material data corresponding to a color material amount of a chromatic color material, and a generation unit configured to generate color material data corresponding to a color material amount of an achromatic color material at the pixel of interest in such a manner that the color material data corresponding to the color material amount of the achromatic color material at the pixel of interest is different from color material data corresponding to a color material amount of the achromatic color material at a pixel adjacent to the pixel of interest.
