Abstract
A color-management apparatus and method which can improve color reproducibility during color-gamut mapping of devices having different color gamuts are provided. The apparatus includes a transformation unit transforming a first color space of an original image supplied from a source device into a second color space, a computing unit computing a plurality of second parameters based on at least one among a plurality of first parameter defining the second color space, and a color-gamut mapping unit performing color-gamut mapping between the source device and a reproduction device reproducing an output image from the original image using the plurality of second parameters.
