    摘要： The disclosure relates to a color gamut mapping device that allows a gamma characteristic for each color to be tuned to match a target gamma curve through color gamut mapping, a tuning method thereof, and an image processor including the same. The color gamut mapping device controls a hue and saturation of an image signal to match a target color gamut using a hue parameter assigned to each of a plurality of hue axes and a saturation parameter assigned to correspond to each of a plurality of saturation control areas of each hue axis, and the color gamut mapping device changes the saturation of the image signal by changing the saturation parameter which is assigned to each hue axis and corresponds to the uppermost saturation control area so that a gamma characteristic for each color of the image signal is changed to match a target gamma curve for each color.

    摘要： Disclosed is a display driving apparatus. The display driving apparatus includes a distance calculator configured to calculate, for a plurality of pixels constituting a frame input to a display panel, distances between respective pixels and a central pixel, a gain calculator configured to divide the frame constituted by the plurality of pixels into an interest area and a non-interest area using the distances between respective pixels and the central pixel, and to determine a gain of each pixel in accordance with an area where the pixel is disposed, and a gain applier configured to generate pixel data using the gain of each pixel. Gains of the pixels disposed in the interest area have a constant value. Gains of the pixels disposed in the non-interest area are decreased in proportion to distances between the pixels in the non-interest area and the central pixel, respectively.
