Abstract:
1. An image processing method for generating a density signal, corresponding to a chromatic material and an achromatic material to be used for forming an image, from a luminance signal, wherein a total amount of recording of the chromatic material is smaller than a total amount of recording of the achromatic material, and a plurality of monochrome modes are provided, the total amount of recording of the chromatic material being different for each of the monochrome modes, and wherein the image processing method comprises: a generating step of generating a density signal, corresponding to a chromatic material and an achromatic material, from a luminance signal of the image, the generating step being a process to be executed if the monochrome mode is set, wherein, in the generating step, the density signal is generated from the luminance signal, by using a look-up table in which an amount of a density signal corresponding to the achromatic material is adjusted, such that for identical luminance signals, a recording density of an image if recording is performed by using a first monochrome mode, included in the plurality of monochrome modes, and a recording density of an image if recording is performed by using a second monochrome mode, included in the plurality of monochrome modes, are equivalent to each other.
