Abstract

An image processing apparatus converts an input color signal into a color signal which falls within a color reproduction range of an image output device. The image processing apparatus includes a representative color setting unit that sets plural representative colors, a first hue setting unit that sets hue for an equi-hue line connecting the representative color and black, a hue correcting unit that corrects hue of the input color signal referring to the first hue setting unit, and a mapping unit that maps the input color signal after whose hue is corrected to a color signal within a color range of the image output device.
