Abstract
Color management which uses a color conversion LUT for transformation from an N-dimensional source device color space (N≧4) to a destination device color space, in which the color conversion LUT is constructed in a two-step process. In the first step, an intermediate color conversion LUT is constructed that converts colors in a three-dimensional device-independent color space through a gamut mapping step and through an inverse destination device transform so as to obtain colors in the destination device color space. In the second step, the overall color conversion LUT is obtained by applying a source device transform to color combinations in the source device color space so as to obtain color values in the three-dimensional device-independent color space, and thereafter performing three-dimensional color look-ups in the intermediate color conversion table.
