Abstract
A method and apparatus for transforming color signals. The transformation is achieved by use of a first, coarse, look-up table and a second look-up table that provides coefficients to be used in calculating a correction vector. The vector of color components from the first look-up table is added to the correction vector to provide the transformed vector. The method and apparatus have particular application in the display of digital video signals.
