Claim 5:
6. The color gamut mapping method of claim 5, wherein the parameter calculator is configured to:
calculate the first to fourth saturation gains by linearly interpolating first to fourth saturation parameters of the first hue axis, which are set for each of the first to fourth saturation control areas to correspond to the first hue axis, and the first to fourth saturation parameters of the second hue axis, which are set for each of the first to fourth saturation control areas to correspond to the second hue axis, for each of the first to fourth saturation control areas according to the calculated hue angle; and
calculate the first and second hue gains by linearly interpolating first and second hue parameters of the first hue axis, which are set for each of the first and second hue control areas to correspond to the first hue axis, and the first and second hue parameters of the second hue axis, which are set for each of the first and second hue control areas to correspond to the second hue axis, for each of first and second hue control areas according to the calculated hue angle.
