Claim 2:
3. An image processing apparatus comprising:
an acquisition unit configured to acquire a pixel value from original data of a print target of a print unit, which is formed by a plurality of pages;
a decision unit configured to decide, based on the pixel value acquired by the acquisition unit 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
a color conversion unit configured to perform color conversion of the original data by the color mapping method decided by the decision unit,
wherein a plurality of color mapping methods as a target to be decided by the decision unit 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,
the decision unit decides the color mapping method to the print color gamut based on whether a pixel value outside the print color gamut is included in a plurality of pixel values acquired by the acquisition unit, and
the decision unit decides the first color mapping method if the pixel value outside the print color gamut is included in the plurality of pixel values acquired by the acquisition unit, and decides the second color mapping method if the pixel value outside the print color gamut is not included in the plurality of pixel values acquired by the acquisition unit.
