  • Color calibration device, color calibration method, and calibration table generation method
    Patent number: 11749163
    Abstract: The invention provides a color calibration device, a color calibration method and a calibration table generation method. The color calibration device includes a calibration table circuit, a ratio circuit and an image processing circuit. The calibration table circuit provides a selected calibration table including a plurality of zone calibration parameters. Each of the zone calibration parameters corresponds to a corresponding zone among a plurality of zones of a display panel. The ratio circuit calculates a subpixel calibration parameter corresponding to a current subpixel according to at least one of the zone calibration parameters in the selected calibration table. The image processing circuit calibrates original subpixel data of the current subpixel according to the subpixel calibration parameter to generate calibrated subpixel data of the current subpixel.
