摘要： The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

摘要： A method for characterizing a colour reproduction device. A first output colour measure responding to a first reference input colour value is measured under normal measurement conditions. The measurement conditions are modified and a second output colour measure responding to the first reference input colour value is measured under the modified measurement conditions. A transformation rule, enabling transformation between the second output colour measure and the first output colour measure, is calculated from the first colour value and the second colour value. A first set of output colour measures responding to a set of input colour values is measured under modified measurement conditions, and the first set of output colour measures is converted, using the transformation rule, to a second set of output colour measures. A system and a control device are also provided.

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.
