摘要： A method of dynamic of gamut control is provided for a display having a multi-spectral (typically multi-color) backlight, and sub-pixels corresponding to the different backlight spectra and at least one common sub-pixel. The display may f be an RGBW display having an RGB backlight. The method includes iteratively calculating the minimum required backlight intensities that will allow all (selected) color points of an image to be represented by the display. The determination for a light source of the backlight is based on determinations of intensities determined for other light sources in a previous iteration.

摘要： Clusters of pixels are defined for use in image compression and decompression. The image information used to define the clusters may include pixel values at predetermined positions relative to a pixel or related motion vectors, gradients, texture etc. During compression of images the image information relative to pixels is examined to determine the cluster to which it belongs. Thus pixels can be classified according to the cluster for their image information. In an embodiment the definitions of the clusters are selected dynamically, dependent on image content. For each cluster a control parameter set is computed for a post-processing operation, such as filter coefficients for filtering or statistical data for locally generating texture. The control parameter set is selected dependent on the image content so that, when the post-processing operation is applied to the image after decompression it will improve image quality for the pixels that are classified as belonging to the cluster. The compressed image and the control parameter sets are transmitted to a decompression apparatus. Upon decompression, the image information that represents the decompressed image is examined to classify pixels according to the clusters and the different control parameter sets for the selected clusters are used to control post-processing at the locations of the pixels.

摘要： A multi-primary conversion (5) of input drive values (RGB) defines a color of a pixel (PI) of a multi-primary display(DP) in an M dimensional color space (XYZ) into N>M output drive values (di) in an N dimensional drive space. The N output drive values (di) drive N sub-pixels (SPi) of the pixel (PI). The color of the pixel (PI) in the color space (XYZ) is defined by linear combinations of N color primaries of the respective N sub-pixels (SPi). The multi-primary conversion(5) comprises: defining a constraint in the color space (XYZ) thereby causing in the color space (XYZ) a convex polytope (U0; L0; V50) defined by vertex points (V10, V11, V12; V20, V21; V50), wherein only colors in the color space (XYZ) belonging to the convex polytope fulfill the constraint, determining exemplary solutions of the output drive values (di) for at least a subset of the vertex points (V10, V11, V12; V20, V21; V50), and constructing the output drive values (di) fulfilling the constraint as a convex combination of the exemplary solutions.

摘要： A display system comprises a color sequential display (201) having a backlight (205) comprising several backlight segments and a light modulating panel (207) comprising pixels having controllable light transmission. A backlight unit (211) determines, for a plurality of backlight segments, backlight chromaticities for fields of an image in response to the image content. An order unit (217) determines a sequential order of the backlight chromaticities for each of the plurality of backlight segments for the image in response to the chromaticities. A driver (219) generates a backlight drive signal for the backlight (205) corresponding to the chromaticities and sequential order. A modulating processor (213) determines light modulating values for the pixels in response to the chromaticities, the sequential order and the image. A driver (221) then generates a light modulating drive signal for the light modulating element corresponding to the light modulating values. The system may improve image quality by reducing spatial cross-talk between the backlight segments.

摘要： A controller for a multi-primary display having M>3 primaries receives a set of input N-primary image color defining values comprising drive values for N primaries for each pixel. A compensator (317) generates a set of compensated N-primary image color (N>=3) defining values by applying a luminance compensation to the values of the set of input N-primary image color defining values where the luminance compensation for each pixel depends on the chromaticity of the pixel. A backlight processor (311) determines backlight levels in response to the compensated N-primary image color defining values. A modifier (313) then generates modified N-primary image color defining values by adjusting the input or the modified N-primary image color defining values or the for the backlight level and a primary converter (315) converts the modified N-primary image color defining values into multi-primary drive values for the display. The approach may e.g. reduce clipping for multi-primary displays with dynamic backlight control by introducing a low complexity pre-processing luminance compensation to existing equipment.
