  • Patent number: 10650784
    Abstract: An image of an HDR signal, in which deterioration in luminance due to adjustment of white balance is suppressed while variations of a color of an image of an SDR signal is suppressed, is displayed. A television (1) that displays an image is which white balance is adjusted includes a determination unit (12) that determines whether an image signal is an HDR signal or an SDR signal, and a display control unit (14) that, in a case where the determination unit determines that the image signal is the HDR signal, changes gain of at least one primary color among primary colors to a value higher than a set value.

  • Patent number: 10600148
    Abstract: A system and method that splices an initial 3D LUT for imaging format conversion into a plurality of smaller LUTs that can be stored in separate RAMs. During operation, the upper 5-bits serve as index values of each component of an incoming GBR pixel and are used to determine which of the smaller RAMs contain the correct index values for the pixel data. Specifically, a first index value can be derived from the incoming GBR pixel data and used to lookup all sub-cube vertices corresponding to the incoming pixel and the corresponding RAMs. After determining the correct RAMs, a predetermined algorithm for each given RAM is applied to find the normalized RAM look-up addresses and identify the correct data for the exemplary imaging format conversion process.

  • Patent number: 10516806
    Abstract: A color image is processed into a renderable image. The color image comprises a plurality of pixels. Each pixel has colorimetry defined in a first color space. The renderable image comprises a plurality of renderable pixels defined by a device-vector in a second color space. For each pixel: a device-vector defined in the second color space is selected (301) based on the colorimetry defined in a first color space of the pixel. The device-vector comprises a plurality of elements. Each element includes an identifier and an accumulated weighting. An element of the selected device-vector is reselected (303) until the accumulated weighting (a) is greater than a threshold value (t) associated with the pixel (305). The levels for each color of the second color space (or mappings) for the currently selected (307) element of the selected device-vector is determined (309) to convert the pixel into a renderable pixel.

    Abstract: The present invention relates to the art of color space conversion technique, and discloses a method for processing RGB data and a system for the same. The method comprises: S1: converting input values of three colors RGB into a HSV color space; S2: adjusting a brightness value V while keeping a hue value H and a saturation value S unchanged in the HSV color space; S3: converting the H, S, V values processed by step S2 from the HSV color space to the R, G, B, W color space to display. By converting the RGB color space to the HSV color space firstly, then enhancing the brightness V while keeping H, S unchanged in the HSV color space, and finally converting the HSV color space to the RGBW color space, it can be achieved that the brightness for display is enhanced while better hue, color saturation and natural color transition are maintained at the same time.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying high bit-depth images using temporal modulation on display devices including display elements that have multiple primary colors. In order to reduce visual artifacts produced by angular metamerism, the display elements are configured to display only those combinations of the different primary colors that satisfy certain constraints. Color combinations of the multiple primary colors that satisfy these constraints are included in a constrained color palette that includes fewer than all the possible colors that can be provided by all combinations of the primary colors.

  • Publication number: 20150062152
    Abstract: A method for correcting colors in an image commences by first defining a set of Red-Green-Blue (RGB) color triplets corresponding to user-selected colors defining a designated are of interest in the image to undergo color correction. The set of RGB color triplets are mapped into in a color space defined by cylindrical coordinates to create a three-dimensional look-up table (3D-LUT) that represents a first color range for the designated area of interest. The 3D-LUT undergoes adjustment to establish a second color range. Thereafter, the image is rendered using the 3D-LUT to replace colors in the designated area of interest with colors in the second color range.

  • Publication number: 20150009229
    Abstract: The current disclosure is directed to systems and methods that process standard video signal data and that control a reflective display panel to brightly display videos and images in colors selected from a broad range of colors. In certain implementations, an input video/image signal is first transformed from a RGB encoding to an encoding based on a new color system that encodes colors using spectral, black, and white components. The reflective display panel includes an array of pixels, with each pixel comprising one or more self-parallelizing interferometric modulators (“SPIMs”). Each SPIM contains a plurality of electrodes disposed on a bottom plate, a fixed top plate, and a movable plate separated by a cavity. Appropriate voltages are applied to the electrodes to vary the cavity depth of the SPIM in order for the SPIM to reflect a color of a particular wavelength or to appear black or white.

  • Patent number: 8928684
    Abstract: An overdrive device includes a training unit, an analysis unit and a Contrast adjustment unit. The training unit establishes a luminance difference look-up table (LUT) having an R2 number of luminance differences. Each of the R2 number of luminance differences represents a luminance difference between a measured display luminance value and a target luminance value of a display device when each of first and second viewing angle images correspond to any value of a grayscale range R. With respect to first and second viewing angle input image data, for pixel data therein corresponding to a same pixel position, the analysis unit looks up the luminance difference LUT to obtain a looked-up luminance difference, and accordingly calculates a luminance difference index. The contrast adjustment unit partially adjusts the grayscale of the second viewing angle image according to the luminance value index to obtain headroom for an overdrive operation.

  • Patent number: 8922580
    Abstract: Modifying a color lookup table includes receiving a first image, a first color lookup table (CLUT) indexed in a first image color space, and a second CLUT indexed in a colorimetric space. Tracer pixels from the second CLUT are generated and retained, each tracer pixel including color coordinates of a corresponding unique node in the first CLUT. Tracer pixels are inserted into the first image, and tracer pixels are tracked. Color adjustments are made using image editing software to generate an adjusted combined image having adjusted tracer pixels. The adjusted tracer pixels are extracted. The second CLUT is converted to a third CLUT having a size N1×N2×N3×N4 by replacing each of the output-device color coordinates of the second CLUT nodes by modified device color coordinates computed from the adjusted color coordinates of the adjusted tracer pixels.
