Abstract
A display device according to an embodiment of the disclosure comprises: a linear gamut mapping unit for deriving a linear gamut mapping result for matching a gamut of an input image signal to a target display gamut; a non-linear gamut mapping unit for deriving a non-linear gamut mapping result for matching the gamut of the input image signal to the target display gamut; and a mixing unit for generating an output image signal by mixing the linear gamut mapping result and the non-linear gamut mapping result. The disclosure may provide an optimal gamut mapping result that is intended by a user and an originator.
