17. An image processing method comprising:
inputting image data;
generating image data having undergone color gamut conversion from the input image data using a conversion unit configured to convert a color gamut of the input image data into a color gamut of a device configured to output the image data;
correcting the conversion unit based on a result of the color gamut conversion; and
controlling execution of the correction for an object included in the input image data,
wherein execution of the correction for the object is controlled based on a positional relationship between the object and another object different from the object,
in a case where the conversion unit is corrected, image data having undergone color gamut conversion from the input image data using the corrected conversion unit is generated, and
in the image data having undergone the color gamut conversion by the corrected conversion unit, a color difference between objects in the image data having undergone the color gamut conversion by the conversion unit before the correction is expanded.
