摘要： A colour quality control device (140) adapted for use in a system (100) for colour correction of an image to be reproduced on at least one reproduction device (120) that is calibrated by a reproduction forward transform (122). The system also comprises a colour correction device (110) adapted to correct at least one colour in the image. The colour quality control device (140) comprises a false contour detection unit (141 ) that uses information from the reproduction forward transform (122) to decide if a contour in the image (322) is a false contour (328) introduced by the transform. This facilitates the operator's work during colour correction. A system and a method are also provided.

摘要： In situation where a capturing device is capturing a first image of a scene comprising a display device displaying a second image, a salient idea is to send both the captured first image and the second image, being displayed by the display device to a processing device, for comparatively processing the first and the second image to determine a characteristic associated with the display device. Being able to process the first image (comprising a displayed second image) together with the original second image advantageously allows to determine various characteristics associated with the display device that altered the displayed second image within the first image, making it different from the initial second image. Characteristics associated with the display device are for example a specular reflection occurring on the display device in the scene and disturbing the capture of the scene. In a second and non-limiting example a characteristic of the display device is the color reproduction function of the display device that makes the displayed second image within a displayed first image be different from the displayed second image in the scene.

摘要： A method and apparatus for inverse tone mapping of an LDR image with computer generated imagery components, such components being also called visual effects, are disclosed. The disclosed method comprises the steps of accessing a first LDR image, the first LDR image being obtained from at least one computer generated imagery component rendered and composited into an LDR reference image or background plate; determining an HDR lighting indication responsive to information extracted from a part of the first LDR image and a respective part of a first intermediate HDR image obtained by applying a first pass inverse tone mapping to said first LDR image; obtaining a second intermediate HDR image by applying a second pass inverse tone mapping to the LDR reference image; obtaining the first HDR image from the computer generated imagery components rendered using HDR lighting indication and composited into the second intermediate HDR image.

摘要： An aspect of present principles is directed to methods and systems for gamut mapping colors from a either a source color gamut or a content color gamut towards a target color gamut. A source hue of the source specific colors and a source hue of the content specific colors is changed towards a target hue of the corresponding target specific colors. Color gamut mapping is performed for the source colors of either the whole source color gamut or the content 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.

摘要： Methods and apparatus for mapping an input image are suggested. The suggested method comprises: determining a computation capability available for the mapping; decomposing the input image into a number M of image portions based on the determined computation capability, M being a positive integer larger than 1; performing mappings on each of the number M of image portions, wherein the mappings are different for at least two of the number M of image portions; and recomposing an output image from the mapped image portions.

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： In order to preserve the discontinuities of an actual gamut surface and/or the discontinuities of its curvature, notably through a smoothing operation, in this method, when at least a vertex of any elementary polygon, the network of which represents an actual gamut boundary, belongs either to a line or a point of discontinuity of this actual gamut boundary, either to a line or a point of discontinuity of curvature of said actual gamut boundary, or both, metadata related to this belongings are added to the definition of the elementary polygons.
