Source color converting method for e.g. phase alternating line video signal, involves mapping colors belonging to source areas in destination color space`s color gamut such that colors of each source area are mapped in same destination area

摘要

The method involves identifying a source area (Tsi), of a set of source areas, to which source colors (OA0-OA2) belong, where the source areas are obtained by partitioning m-cube of color gamut of a source color space. The source colors are mapped in an n-cube of color gamut of a destination color space to obtain destination colors (OA0, OA`1, OA`2). The n-cube is partitioned into a set of k destination areas. The mapping operation is adapted such that the set of colors of each source area is mapped in a same destination area (Tdi).
