Abstract
An image processing device calculates saturation of each pixel on the basis of multicolor image data; determines a pixel as a chromatic/achromatic pixel based on a threshold value; generates achromatic pixel data for formation of an image using only a color material of black; generates chromatic pixel data constituting a double color image and containing single color image data for formation of an image realized by a combination of color materials; generates for the chromatic pixel, single color image data such that the consumption of a color material of a chromatic color corresponding to the single color increases with increase in the saturation of the chromatic pixel. This makes it possible to generate double color image data by which high contrast and rich tone reproduction can be realized and the boundary between the achromatic region and the chromatic region can be expressed with natural gradation.
