Patent ID: 7760393

Claim:
A method of applying, to data of a color space depending on an input device, input conversion for converting into data of a device-independent color space, gamut mapping for mapping on data of a gamut of an output device, and output conversion for converting into data of a color space depending on the output device, the method comprising the steps of: generating individual conversion characteristic data of one of the input conversion, the gamut mapping, and the output conversion for each device information indicating one of the input device and the output device, and for each conversion setting; generating integrated conversion characteristic data by combining conversion characteristics of the input conversion, the gamut mapping, and the output conversion for each combination of the device information of the input device and the output device, and for each conversion setting; converting input data into output data using one of the individual conversion characteristic data and the integrated conversion characteristic data; editing the conversion setting of one of the input conversion, the gamut mapping, and the output conversion; and modifying the individual conversion characteristic data and the integrated conversion characteristic data in accordance with the edited contents.
