Abstract:
1. An image processing apparatus comprising: a setting unit configured to set a monochrome mode for printing a monochrome image on a printing medium or a color mode for printing a color image on the printing medium; an acquisition unit configured to acquire monochrome image data indicating a gradation value of a gray line, in a case where the monochrome mode is set by the setting unit; a conversion unit configured to convert the monochrome image data acquired by the acquisition unit into intermediate image data by using a first lookup table, wherein the first lookup table associates the gradation value of the gray line with a coordinate value of a color space; and a transfer unit configured to transfer the intermediate image data converted by the conversion unit to a determination unit configured to determine a color material amount, to print the monochrome image on the printing medium, by using a second lookup table, wherein the second lookup table associates the coordinate value of the color space with the color material amount, wherein a combination of the gradation value and the color material amount is assigned to the coordinate value of the color space, and wherein the first lookup table and the second lookup table are defined based on the color space.
