Method of creating color-mapping lookup table and color-mapping method using the same

摘要

Disclosed is a method of creating a color-mapping lookup table and a color-mapping method using the same. The method of creating a color-mapping lookup table includes; obtaining color-space data for respective solid colors specified as lattice points of the color-mapping lookup table, obtaining color-space data for respective achromatic colors specified as lattice points of the color-mapping lookup table, and tabulating the color-space data for the respective solid colors specified as the lattice points and the color-space for the respective achromatic colors specified as the lattice points. Therefore, the methods can create a color-mapping LUT in which significant colors such as solid colors or achromatic colors are specified as lattice points, so that significant colors are more optimally reproduced since device data for the significant colors are not calculated through interpolation.
