Abstract:
A gamut compressing device for compressing video data in a first gamut into video data in a second gamut. The device includes a compression unit compressing a value of color data in the first gamut, not contained in the second gamut, into a value of color data contained in the second gamut through a predetermined compression calculation. A gradation generating unit generates gradation such that a plurality of values of color data having the same value as a result of the compression become different in the second gamut.
