Abstract
A color matching process which can respond to a type of object to be processed is automatically performed by a printer driver. The color conversion method converts first color image information into second color image information output to a color image outputting apparatus. It is determined whether or not the first color image information includes an instruction for designating a color matching method. A type of each object included in the first color image information is discriminated when the first color image information does not include the instruction for designating a color matching method. One of a plurality of color matching methods suitable for the type of each object is selected in accordance with previously prepared correspondence information between each type of object and each color matching method. A color matching process is performed on each object in the first color image information by using the selected color matching method so as to convert the first color image information into the second color image information.
