Zusammenfassung:	An image processing apparatus obtains image data that is defined as a first color gamut, transforms the image data into image data that is defined as a second color gamut, using color transformation information, and when, as a result of transformation, a first pair of color values included in the image data is transformed into a second pair of color values that have a color difference that is not perceived as different colors, generates second color transformation information such that the first pair of color values is transformed into a third pair of color values that have a color difference that is perceived as different colors as a result of transformation using the second color transformation information. A saturation difference of the third pair of color values is larger than a saturation difference of the second pair of color values.
