Abstract
The present invention is directed to an apparatus and a method to improve color matching between original color images and reproductions of those images. The present invention comprises an input device and an output device by obtaining a first transformation that maps points representing colors within a first output-device-gamut from a device-dependent color space to points in a device-independent color space, obtaining a second transformation that maps points representing colors within a second output-device-gamut from the device-dependent color space to points in the device-independent color space, and deriving the color space transformation such that it maps a respective point from the device-dependent color space to a corresponding point in the device-independent color space according to whether the respective point is within either or both of the first and second output-device gamuts.
