Claim 23:
24. 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;
a color conversion unit configured to perform color conversion of the original data by the color mapping method decided by the decision unit; and
a setting unit configured to set a color gamut corresponding to the original data,
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,
each of the first color mapping method and the second color mapping method is a color mapping method from the color gamut set by the setting unit to the print color gamut, and
the setting unit sets the print color gamut as a default color gamut, and if a pixel value acquired by the acquisition unit is outside the print color gamut, the setting unit expands the default color gamut such that the default color gamut includes the pixel value outside the print color gamut, and sets the expanded color gamut as the color gamut corresponding to the original data.
