Patent ID: 7619773

Claim:
A method for transforming source color image data depending on a source device into destination color image data depending on a destination device, comprising the steps of: accessing a source color data file of the source device and a destination color data file of the destination device, the source and the destination color data file containing colorimetric data and corresponding device data; constructing a source color transform based on the source color data file by using a source color transform constructing function; constructing a destination color transform based on the destination color data file by using a destination color transform constructing function; generating a source gamut boundary of the source device and a destination gamut boundary of the destination device; constructing a gamut transform based on the source gamut boundary of the source device and the destination gamut boundary of the destination device; incorporating the source color transform, the gamut transform and the destination color transform to generate an incorporated transform; transforming the source color image data into the destination color image data by using the incorporated transform; saving the source color transform for future use; and saving the incorporated transform for future use.
