Claim 24:
25. An image processing method comprising:
acquiring a pixel value from original data of a print target of a print unit, which is formed by a plurality of pages;
deciding, based on the acquired pixel value and a print color gamut of the print unit, a color mapping method to the print color gamut for at least one of a page included in the plurality of pages and a portion in the page; and
performing color conversion of the original data by the decided color mapping method,
wherein in the deciding of a color mapping method, a plurality of color mapping methods as a target to be decided include a first color mapping method of compressing a color space in the print color gamut, and a second color mapping method different from the first color mapping method,
in the deciding of a color mapping method, the color mapping method to the print color gamut is decided based on whether a pixel value outside the print color gamut is included in a plurality of acquired pixel values, and
in the deciding of a color mapping method, the first color mapping method is decided if the pixel value outside the print color gamut is included in the plurality of acquired pixel values, and the second color mapping method is decided if the pixel value outside the print color gamut is not included in the plurality of acquired pixel values.
