    摘要: An aspect of present principles is directed to methods and systems for gamut mapping source colors into target colors from a source color gamut towards a target color gamut. A difference may be determined source specific colors and corresponding target specific colors. A source hue of the source specific colors is adaptively changed towards a target hue of the corresponding target specific colors based on the difference to determine mapped specific colors. Color gamut mapping is performed for the source colors of the source color gamut towards the target color gamut based on the mapped specific colors. The specific colors are selected from primary colors, secondary colors, a group of primary colors and secondary colors. The difference is based on at least one selected from the group of hue, saturation and lightness of the source specific colors and the corresponding target specific colors.

    摘要: According to this method, upon reception of a color transform (T 2 ) associated with a main sequence (S 2 ), a transition sequence (ST 1-2 ) is generated from successive images of this main sequence such that the first image of this transition sequence is an image received after reception of this color transform (T 2 ), transition color transforms associated with images of said transition sequence (ST 1-2 ) are generated by blending a color transform (T 1 ) associated with a previous main sequence (S 1 ) or no color transform (U) with the second color transform (T 2 ), and each image of this transition sequence (ST 1-2 ) is processed using the transition color transform associated with said image.

    摘要: For the mapping in a non-linear color space of source colors belonging to a same constant-hue leaf, a lightness mapping function can be used which is based on a cusp lightness condition stating that a source cusp color of this leaf should be mapped into a corresponding target cusp color of this leaf. Source and target cusp colors are determined by the intersection of a source and target cusp lines with this leaf. The invention describes a method providing simplified source and target cusp lines based on a convex hull algorithm which are used instead to determine modified source and target cusp colors for the definition of the lightness mapping function.

    摘要: The method comprises segmenting lines into regions of saturated pixels, and, for each of these saturated regions, selecting at least one color channel that is not saturated, then, for each pixel of said region, adding to the color information provided by the saturated color channel for said pixel a difference between the color information provided by the selected non-saturated color channel for said pixel and a baseline color value computed for the region of this pixel.

    摘要: According to the invention, the mapping operations aresubdivided into two main steps: first, a content-dependent mapping of colors from a source content color gamut into an intermediate color gamut which is common to all images to map, and second, a device-dependent mapping of colors from this intermediate color gamut into the target color gamut.
