摘要： Before the transmission of the source color values of the images of each group Gk of images of this sequence, a partial color transform LUT related to this group Gk is generated, then transmitted, —and, a resultant color transform LUT related to said group Gk is reconstructed by combining the transmitted partial color transform look up table of this group Gk with, if any, all the other partial color transform look up tables that have been previously transmitted, —then each images of said group are color transformed using this LUT. The invention allows a good precision of color transformation with a limited bandwidth.

摘要： In the different mapping planes, described by plane coordinates, of the color space in which colors to map are represented, a uniformity testing curve can be found that intersects all mapping trajectories of this mapping plane and, at any intersection of a mapping trajectory with said uniformity testing curve, the gradients calculated in said plane coordinates of the intersecting mapping lines and the first derivation along this uniformity testing of these gradients are continuous.Thank to the invention, colors are better preserved after mapping, even if there are different mapping methods in the same mapping plane.

摘要： A method for image processing of digital image pixels. Pixels are preferably filtered spatially and dithered, and the value for at least one colour component is bit reduced. The space freed by the bit reduction is used to allocate a look-up table selection bit that indicates which look-up table (LUT), from a plurality of small LUTs partitioned from a bigger LUT, should be used for the colour transform. The transformed pixels are then selected according to the used LUT, format converted and output. The invention, which also covers an apparatus and a pre-processing module, enables an apparatus with a LUT to be used both as a single full-rate LUT apparatus and as a lower-rate n smaller LUT apparatus.
