Claim 0:
1. An image processing apparatus comprising:
an acquisition unit configured to acquire original data of a print target of a print unit, which is formed by one page or a plurality of pages;
a division unit configured to divide the original data into a plurality of partial original data including at least a first partial original and a second partial original;
a decision unit configured to decide a first color mapping method to a print color gamut for the first partial original based on a pixel value included in the first partial original and the print color gamut of the print unit and further configured to decide a second color mapping method to the print color gamut for the second partial original based on a pixel value included in the second partial original and the print color gamut of the print unit;
a color conversion unit configured to perform color conversion of the first partial original by the first color mapping method decided by the decision unit, and perform color conversion of the second partial original by the second color mapping method decided by the decision unit; and
a setting unit configured to set a color gamut of a partial original corresponding to the partial original data,
wherein each of the first color mapping method and the second color mapping method is a color mapping method from the color gamut of the partial original data 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 of the partial original data 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 of the partial original corresponding to the partial original data.
