ABSTRACT:
A color determination device sections a hue plane, in which unit data constituting determining image data is mapped, into partial regions by a color determination boundary, and carries out a color determination according to a number of unit data belonging to each partial region. A gradient of a hue boundary line is a rational number. For example, an affine conversion or the like is executed on the hue plane, and the color determination boundary line is matched with an axis of the hue plane. Accordingly, a calculation amount is reduced in a determination processing for determining in which partial region the unit data belongs.
