  • Patent number: 10313647
    Abstract: According to this method, upon reception of a color transform associated with a main sequence, a transition sequence 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, transition color transforms associated with images of said transition sequence are generated by blending a color transform associated with a previous main sequence or no color transform with the second color transform, and each image of this transition sequence is processed using the transition color transform associated with said image.

  • Patent number: 10298897
    Abstract: Method wherein each image of the content is transformed using at least one pre-transformed image which is associated with a key image of this content wherein, from each key image and an associated pre-transformed image, a color transform is derived, and wherein each color transform is applied to a selection of images of this content which is associated with said key image. Applied to a content broadcast system comprising a server and a receiver to which are connected several types of display devices, the invention advantageously makes it possible to adapt the content to these different types.

  • Patent number: 10284750
    Abstract: Said method comprises a first cusp-oriented lightness-mapping step and a second lightness-mapping step in which a source color (N) is mapped into a mapped color (N?) having the same hue (H?=H) and the same chroma (C?=C) as the source color, where the second mapping step is defined such as to bring more colors in a target color gamut and more colors closer to the boundary of this target gamut.

  • Patent number: 10270942
    Abstract: Source colors are mapped within a mapping segment starting at a preserved gamut boundary color (PC) and ending at a target gamut boundary color (IT-C) of the chromaticity plane, corresponding, in a linear 3D color space, to an intersection of the target color gamut (TCG) with a plane of constant luminance and with a mapping plane (MKO) comprising said source color (M), a black point (K) and a white point (O).

  • Patent number: 10270943
    Abstract: 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.

  • Publication number: 20180342104
    Abstract: In a 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.

  • Patent number: 10129513
    Abstract: The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

  • Patent number: 10116919
    Abstract: The present invention generally relates to a method and arrangement for estimating said at least one cross-channel color mapping model from a set of tuples of corresponding colors relative to at least two images. The method is characterized in that it uses a processor for selecting at least one intermediate tuple of corresponding colors from the set of tuples of corresponding colors by using at least one channel-wise color mapping model, and for estimating the at least one cross-channel color mapping model from the at least one intermediate selected tuple of corresponding colors.

  • Publication number: 20180191925
    Abstract: For the mapping in a non-linear color space of source colors belonging to a same constant-hue leaf, instead of using a lightness mapping function based only 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, it is proposed to build such a function also on other source cusp color(s) and other target cusp color(s) having hues different from that of said leaf. Preferably, the hue interval in which these other colors are considered is representative of the curvature of the non-linear color space at the position of colors of this constant-hue leaf.

  • Publication number: 20170374345
    Abstract: A method for creating a pair of stereoscopic images is described. The method includes using at least one lightfield camera which receives respective required camera parameters for a left view and a right view. The required camera parameters define a theoretical stereo image pair to acquire respective actual camera parameters for respective sub aperture images that are generated based on the captured image by the lightfield cameras, to determine a best matching sub aperture image for the left view by comparing the required camera parameter for the left view with the actual camera parameters for the respective sub aperture images, to determine a best matching sub aperture image for right view by comparing the required camera parameter for right view with the actual camera parameters for the respective sub aperture images, and to associate the best matching sub aperture image for left view and the best matching sub aperture image for right view as a pair of stereoscopic images.

  • Patent number: 9854136
    Abstract: There are provided a method and system for color correcting displays with different color gamuts. The method includes performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut. The performing step includes mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut. The performing step further includes generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut. The subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut.

  • Publication number: 20170359491
    Abstract: According to this method, the mapping color LUT has input colors that sample not only a source color gamut (included in an input encoding color space in which inputs colors of this LUT are encoded) but also a portion of the input encoding color space which is not included in the source color gamut. Preferably, this color LUT further includes output colors located outside the target color gamut. Accuracy of the mapping is improved, notably for source colors located near the boundary of the source color gamut.
