Abstract
In a color conversion definition correcting method, image data for a target device is converted into image data for an output device using a color conversion definition made by combining a profile for a target device with a profile for an output device, and an image is output according to the converted image data. The profile for the target device is corrected as follows. Coordinate values out of a color gamut for the output device in the calorimetric color space, of coordinate values in a color gamut for the target device in the calorimetric color space, all go in the color gamut for the output device. Likely, calorimetric values for the color chart output from the target device are corrected. The corrected profile for the target device is further corrected according to the calorimetric values after correction and the calorimetric values of the color chart output from the output device.
