Abstract: In some examples, a method includes dividing, by a first display device, video data into multiple buffers corresponding to regions of the video data. In some examples, the method includes receiving, by the first display device, an indicator from a second display device. In some examples, the method includes controlling, by the first display device, color processing of data of a first buffer of the multiple buffers based on the indicator to coordinate with the second display device.

Abstract: Systems and methods for performing color mapping operations. One system includes a processor to perform post-production editing of image data. The processor is configured to identify a first region of an image and identify a second region of the image. The first region includes a first white point having a first tone, and the second region includes a second white point having a second tone. The processor is further configured to determine a color mapping function based on the first tone, apply the color mapping function to the second region of the image, and generate an output image.

Abstract: A device applies a pre-function to an input signal to obtain an intermediate signal, wherein the pre-function has a linear section part of the input range. The device then applies a LUT including LUT entries that define a linear section and that delimit the range of the intermediate signal that corresponds to the part of the input range, resulting in an output signal that can be linearly processed through the pre-function and the LUT. The device can process a signal with positive and negative values, where one of these lies in the part of the input range that results in linear processing.

Abstract: Methods (300, 310, 320) for compensating colors based on luminance adjustment parameters and the related display devices. An electronic device (100) comprises: a display comprising an array of pixels (210, 220, 230，240) and a control circuit (130) electrically connected to the display. Pixels (210，220，230，240) in the array comprise a plurality of first sub-pixels defining a first color area (401，501) in a chromaticity plane (400，500，800，1000，1100，1200，1300), a plurality of second sub-pixels defining a second color area (402，502) in the chromaticity plane (400，500，800，1000，1100，1200，1300) and a plurality of third sub-pixels defining a third color area (403，503) in the chromaticity plane (400，500，800，1000，1100，1200，1300). The plurality of first sub-pixels is associated with a first primary color, the plurality of second sub-pixels is associated with a second primary color, and the plurality of third sub-pixels is associated with a third primary color. The control circuit (130) is configured to receive an input image signal and generate a control signal to the display for driving each pixel of the display to output light in a virtual color gamut (817，1019，1117，1217，1219，1317). The virtual color gamut (817，1019，1117，1217，1219，1317) of the display includes a first virtual color gamut including a first chromaticity coordinate point of the first primary color, a second virtual color gamut including a second chromaticity coordinate point of the second primary color, a third virtual color gamut including a third chromaticity coordinate point of the third primary color, and a fourth virtual color gamut. The fourth virtual color gamut is among the first, second and third color areas (401，501，402，502，403，503) on the chromaticity plane (400，500，800，1000，1100，1200，1300) and does not overlap any of the first, second or third color areas (401，501，402，502，403，503).

Abstract: The present disclosure relates to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may detect at least one of a scene change between successive frames of a plurality of frames or a threshold number of received frames of the plurality of frames. The apparatus may also generate at least one of a saliency map, an object segmentation map, or a depth map based on a down-sampled image of a first frame. The apparatus may also apply a CMF for a color space associated with the plurality of frames to the plurality of pixels in one or more subsequent frames of the plurality of frames, the CMF being applied until at least one of a subsequent scene change or a subsequent threshold number of received frames.
