Abstract
A bi-color-image-signal generating apparatus includes a reception unit and a generating unit. The reception unit receives specification of a specified color in a case of generating a bi-color image signal from a color image signal. The bi-color image signal has color components representing two colors which are an achromatic color and a chromatic color that is the specified color. The generating unit obtains an amount of each color material which is to be used to form an image having the two colors from the color image signal on the basis of a brightness of the specified color, an amount of each color material which is necessary for image formation using the specified color, and a brightness of the color image signal, and generates the bi-color image signal from the color image signal using the obtained amount of each color material.
