摘要： This determination comprises: defining key constant-hue leaves such as to partition the gamut mapping color space into angular hue sectors; for each key constant hue leaf, defining a key hue leaf chroma mapping function; for each angular hue sector, defining a continuous angular hue sector chroma mapping function such that, for any source color belonging to one of the two key constant-hue leaves delimiting this angular hue sector, this continuous chroma mapping function allows to map the chroma of said source color according to the key hue leaf chroma mapping function of the key constant-hue leaf to which said source color belongs. Preferably, this mapping functions are non linear polynomials.

摘要： Before the transmission of the source color values of the images of each group G k of images of this sequence, a partial color transform LUT related to this group G k is generated, then transmitted, - and, a resultant color transform LUT related to said group G k is reconstructed by combining the transmitted partial color transform look up table of this group G k 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： A method for characterising a colour device (401). A first transform (305) is calculated (304) from first input colours (302) and first output colours (303) measured (301) by an optical instrument (403). An intermediate set of output colour values (306) is obtained and transformed (307), using the transform (305), into a second set of input colour values (308), which are used to obtain (309) a second set of output colour values (310). The second sets of input and output colour values (308, 310) are used to calculate (311) a second transform (312). By a judicious choice of intermediate output colour values, e.g. in the Lab colour space, it is possible to obtain a transform that is extra accurate for colours for which the eye is especially sensible. Also provided are a system and a device.
摘要翻译：一种用于表征彩色装置（401）的方法。通过光学仪器（403）从第一输入颜色（302）和测量的第一输出颜色（303）计算第一变换（305）（304）。使用变换（305）获得输出颜色值（306）的中间集合并将其变换（307）到第二组输入颜色值（308）中，用于获得（309）第二组输出颜色值（310）。第二组输入和输出颜色值（308,310）用于计算（311）第二变换（312）。通过明智地选择中间输出颜色值，例如在实验室色彩空间中，可以获得对眼睛特别敏感的颜色更加精确的变换。还提供了系统和设备。
