Abstract: The invention relates to methods and systems for displays with chromatic correction with differing chromatic ranges. A method comprises carrying out a chromatic correction on the content of an image source, by means of at least one of a display of non-reference type with a non-reference chromatic range and a display of the reference type with a reference chromatic range. The above step includes reformatting (530) the content of the image source to give a reformatted image source content which has undergone a chromatic correction for display on displays of the non-reference type with a non-reference chromatic range. The above step also comprises generation (586) of metadata for mapping chromatic range which chromatically transforms the reformatted image content which has undergone a chromatic correction for display on displays of the reference type with a reference chromatic range. The source image content is only reformatted for display of the non-reference type with the non-reference chromatic range.

Abstract: The invention relates to methods and systems for displays with chromatic correction having differing chromatic ranges. A method comprises carrying out (530) an initial chromatic correction on an image content source by means of a display of the reference type having a reference chromatic range to give a reformatted image content having undergone a chromatic correction for display on displays of the reference type with the reference chromatic range. The method further comprises determining (586) a first set of metadata defining a description of mapping a chromatic range for a chromatic range mapping of a display of the non-reference type with a non-reference chromatic range into the display of the reference type. The method further comprises carrying out (535) an ultimate chromatic correction by means of the display of the non-reference type and reformatted image content having undergone a chromatic correction to give a second set of metadata relating to displays of the non-reference type with the non-reference chromatic range. The method further comprises generating (566) a final set of metadata from the first set of metadata and the second set of metadata for an ultimate chromatic transformation which chromatically transforms the reformatted image content having undergone a chromatic correction for display on a display of the non-reference type for client use. The image source content is reformatted for client use only by displays of the reference type having the reference chromatic range.

Abstract: The invention relates to methods and systems for displays with chromatic correction with differing chromatic ranges. A method comprises carrying out a chromatic correction on the content of an image source, by means of at least one of a display of non-reference type with a non-reference chromatic range and a display of the reference type with a reference chromatic range. The above step includes reformatting (530) the content of the image source to give a reformatted image source content which has undergone a chromatic correction for display on displays of the non-reference type with a non-reference chromatic range. The above step also comprises generation (586) of metadata for mapping chromatic range which chromatically transforms the reformatted image content which has undergone a chromatic correction for display on displays of the non-reference type with a non-reference chromatic range. The ultimate inverse chromatic range mapping is an inverse function of a chromatic range mapping applied during the chromatic correction to give the reformatted image content which has been subjected to a chromatic correction for display on displays of the reference type with the reference chromatic range. The source image content is only reformatted for the displays of the reference type with the reference chromatic range.

Abstract: A method for image processing of digital image pixels. Pixels are preferably filtered spatially (212) and dithered (214), and the value for at least one colour component is bit reduced (216). The space freed by the bit reduction is used to allocate a look-up table selection bit (218) that indicates which look-up table (LUT) (123), from a plurality of small LUTs partitioned from a bigger LUT (122), should be used for the colour transform (222). The transformed pixels are then selected (232) according to the used LUT, format converted (234) and output (236). The invention, which also covers an apparatus (100) and a pre-processing module (110), 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.

Abstract translation: 一种用于数字图像像素的图像处理的方法。 像素优选在空间上被滤波（212）和抖动（214），并且至少一个颜色分量的值被减少（216）。 通过比特缩减释放的空间用于分配从多个较大LUT（122）分割的多个小LUT中的哪个查找表（LUT）（123）的查找表选择位（218） 应该用于颜色变换（222）。 然后根据所使用的LUT，格式转换（234）和输出（236）来选择（232）转换的像素。 本发明还包括装置（100）和预处理模块（110），使具有LUT的装置既可用作单个全速率LUT装置，也可用作较低速率的n个较小的LUT装置。
