Abstract:
A color image processing method comprising the steps of:first selecting a first color processing function defining color characteristics, based on a standard color space, of an input unit; second selecting a second color processing function defining color characteristics, based on the standard color space, of a display unit; third selecting a third color processing function defining color characteristics, based on the standard color space, of an image formation unit; selecting either a first mode for previewing by synthesizing the selected first, second and third color processing functions or a second mode for previewing by synthesizing the selected first and second color processing functions in accordance with an instruction from a user; synthesizing either the selected first, second and third color processing functions or the selected first and second color processing functions so as to generate a composed color processing function in accordance with the selected mode; performing color processing on input image data, by using the composed color processing function so as to generate image data for preview; and outputting the image data for preview, into the display unit so that the display unit can preview an image to be formed by the image formation unit; wherein, in a case where color gamuts of the input unit and of the image formation unit differ and the user does not accept a difference between the color gamuts, the first mode is selected in said selecting step, and in a case where the user accepts the difference between the color gamuts or the color gamuts do not differ substantially from each other, the second mode is selected in said selecting step.
