Claim Text:
1. A device for processing an image, the device comprising: a hue compensator that converts a hue of input signals having a first color gamut representing image data to output hue conversion signals; a gamut converter that outputs gamut conversion signals by converting the input signals, the gamut conversion signals having a second color gamut to display the input signals on an image display device representing the second color gamut narrower than the first color gamut; a blend coefficient setter that sets a blend coefficient defining a synthesis ratio of the hue conversion signals and the gamut conversion signals based on saturation obtained from the input signals; and a color synthesizer that generates synthesized image signals by synthesizing the hue conversion signals and the gamut conversion signals at a ratio according to the blend coefficient, wherein the hue compensator converts the hue of the input signals such that a value of each component of the hue conversion signals is from 0 to 1 when a value of each component of the input signals is from 0 to 1, and wherein, the hue conversion signals and the input signals satisfy Equation 1 when the input signals become (Rin, Gin, Bin) [Eij] and [Mij] are matrices, a value of each component of [Eij] is a constant being 0 to 1, a value of each component of [Mij] is a function of the input signals, and a value of each component of [Mij] is from 0 to 1.
