Abstract
Mapping of color gamut in a three-dimensional color space is performed by converting coordinates of source reference points to coordinates of destination reference points, and converting coordinates of an initial point to coordinates of a target point based on a first relationship among a first set of volumes and a second relationship among a second set of volumes. The first set of volumes are defined at least in part by the initial point and at least a subset of the source reference points, and the second set of volumes are defined at least in part by the target point and at least a subset of the destination reference points.
