20090102968 | Color Metadata for a Downlink Data Channel - 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. | 04-23-2009 |
20090141041 | Mapping method along anchored mapping trajectories with improved uniformity - In the different mapping planes, described by plane coordinates, of the color space in which colors to map are represented, a uniformity testing curve can be found that intersects all mapping trajectories of this mapping plane and, at any intersection of a mapping trajectory with said uniformity testing curve, the gradients calculated in said plane coordinates of the intersecting mapping lines and the first derivation along this uniformity testing of these gradients are continuous. | 06-04-2009 |
20100265264 | METHOD, APPARATUS AND SYSTEM FOR PROVIDING COLOR GRADING FOR DISPLAYS - A method, apparatus and system for providing color grading or color correction for displays includes a plurality of virtual device models where each virtual device model has a virtual model specification (VMS) which controls a display feature. Each display includes a display specification including a display requirement or requirements. An apparatus of the present invention is configured to compare the display feature of at least one VMS against the display requirement of the display specification to determine a best match therebetween to select a virtual device model to control a display picture. Color correction is further provided in post production using the VMS to provide consistency across multiple display types. | 10-21-2010 |
20130002810 | OUTLIER DETECTION FOR COLOUR MAPPING - A method and an arrangement for an improved outlier detection for colour mapping are recommended, wherein a neighborhood of a partially colour compensated test-image by comparing the initially corrected test-image with a reference image in a neighborhood comparator is used for outlier detection and not outlier detection of at least two images for colour mapping. | 01-03-2013 |
20130033528 | METHOD FOR CONTROLLING AN IMAGE DISPLAY DEVICE TO ALLOW THE SAME PERCEPTION OF COLOURS OVER A LARGE VARIETY OF OBSERVERS - For each colour, the method comprises the following steps: —converting the first set of colour coordinates (R | 02-07-2013 |
20130077859 | METHOD AND SYSTEM FOR COLOR LOOK UP TABLE GENERATION - In accordance with an exemplary embodiment, a method is provided to generate a color look up table for multiple images. The method includes selecting color points from a first image. The first color points comprise weak image texture. The method also includes identifying feature points in a spatial neighborhood of each first color point. Additionally, the method includes identifying feature points from a second image. The second feature points correspond to the first feature points. The method also includes determining a color points in the second image. The second color points correspond to the first color points, and are determined using a spatial interpolation of the first plurality of color points from the first plurality of feature points and then applying the obtained spatial interpolation to the second plurality of feature points. Further, the method includes generating the color lookup table. | 03-28-2013 |
20130286286 | METHOD OF PROCESSING A VIDEO CONTENT ALLOWING THE ADAPTATION TO SEVERAL TYPES OF DISPLAY DEVICES - 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. | 10-31-2013 |
20140168250 | METHOD FOR CONTROLLING AN IMAGE DISPLAY DEVICE TO ALLOW AN OBSERVER TO PERCEIVE COLOURS AS ANOTHER OBSERVER - Method for transforming a first version of a color to be reproduced by a proof viewing device a into a second version of the same color to be reproduced by the same proof viewing device in a way that a first human observer perceives this color reproduced on said proof viewing device according to said second version as this color is perceived on a final color reproduction device by a second human observer having human visual characteristics different from those of the first observer. | 06-19-2014 |
