Claim 25:
26. 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;
performing color conversion of the original data by the decided color mapping method;
determining whether an acquired first pixel value and an acquired second pixel value are pixel values outside the print color gamut; and
determining whether the first pixel value and the second pixel value satisfy a condition,
wherein in the deciding of a color mapping method, a plurality of color mapping methods as a target 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,
wherein 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
wherein in the deciding of a color mapping method, if it is determined in the determining that the condition is satisfied, the first color mapping method is decided.
