Color of a color image may be adjusted by a color adjustment apparatus, image display apparatus, and color adjustment method to enable easier distinction between objects shown in the image. A parameter defines a range of saturation to be adjusted within saturation before color adjustment and a range of change of the saturation after color adjustment compared to the saturation before color adjustment. The color adjustment apparatus calculates the saturation from an image signal, calculates the saturation after color adjustment according to the saturation before color adjustment such that the saturation in the range determined by the parameter increases/decreases by an amount determined by the parameter, and generates an image signal from the saturation after color change. By determining the parameter such that the saturation difference between prescribed colors is greater after color adjustment, the difference in color between a plurality of objects shown in the image is increased.

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.

A digital image processing circuit processes macro-pixels of a digital image. A gain control parameter of each pixel of the macro-pixel of the digital image is determined based on a location of the pixel in the digital image. Relative pixel positions of the pixels of the macro-pixel are determined, the relative pixel positions representing pixel positions with respect to color grids. A gain value of each pixel of the macro-pixel is determined based on the relative pixel positions. The gain values are modified based on the gain control parameters. The modified gains are applied to the pixels of the macro-pixel.
