    摘要： Method of mapping source colors from a source color device having an actual source gamut that is represented by a source convex (gamut boundary descriptor) and a source non-convex into target colors for a target color device having an actual target gamut that is represented by a target convex and a target non-convex, comprising, 1—if the source color to map is located outside the source non-convex, a pre-mapping step that maps the source color into the source non-convex, 2—if the mapped target color is located outside the target non-convex, a post-mapping step that maps the target color into the target non-convex. This method allows precise gamut mapping while allowing also for simple geometrical operations using convex gamuts.

    摘要： A colour quality control device adapted for use in a system for colour correction of an image to be reproduced on at least one reproduction device that is calibrated by a reproduction forward transform. The system also comprises a colour correction device adapted to correct at least one colour in the image. The colour quality control device comprises a false contour detection unit that uses information from the reproduction forward transform to decide if a contour in the image is a false contour introduced by the transform. This facilitates the operator's work during colour correction. A system and a method are also provided.

    摘要： According to the method, starting from the chromatic components xS, yS of the color vector to be converted, the components of an intermediate color vector RINT-CR, GINT-CR, ΣINT-CR are-interpolated, whose chromatic components, expressed in the source color space are: xINT-CR=xS, yINT-CR=yS; starting from the luminance component SS of the color vector to be converted and from the luminance component ΣINT-CR of the intermediate color vector, the luminance component ΣD of the converted color vector is interpolated; the chromatic components RD, GD of the converted color vector are calculated from its luminance component ΣD and from the components of the intermediate color vector RINT-CR, GINT-CR, ΣINT-CR. The conversion methods of the prior art are substantially improved.

    摘要： To describe the actual color gamut, a hierarchical structure is proposed which comprises, from bottom to top: Gamut Components: each GC is a surface, generally described as a set of connected elementary triangles or polygons. Gamut Hulls: each GH is a closed surface formed by the concatenation of connex Gamut Components. Gamut Instances: each GI is an alternative Gamut Boundary Description of the same actual gamut and is built by the union of the volume(s) bordered by at least one Gamut Hull. Such a Gamut Boundary Information may be notably used for gamut mapping operations. Among advantages of the invention, are flexibility and adaptation to available memory and bandwidth capabilities.

    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 color 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 color 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.
