Abstract:
1. An image processing apparatus configured to convert image data into color material data including (i) color material data indicating a color material amount of a chromatic color material and (ii) color material data indicating a color material amount of an achromatic color material, the image processing apparatus comprising: a CPU (central processing unit) coupled to a memory; a conversion unit configured to convert image data of a pixel of interest into (i) the color material data of the chromatic color material; a determination unit configured to determine (ii) the color material data of the achromatic color material on the pixel of interest based on (A) coloring information corresponding to the converted color material data of the chromatic color material and (B) coloring information that occurs at surrounding pixels that surround the pixel of interest; and a calculation unit configured to calculate coloring information that occurs at the pixel of interest based on (C) coloring information corresponding to a combination of (i) the converted color material data of the chromatic color material and (ii) the determined color material data of the achromatic color material and (B) the coloring information that occurs at the surrounding pixels, wherein the conversion unit, the determination unit, and the calculation unit are realized by the CPU.
