Abstract
The present disclosure provides a gamut mapping method and a system. The method includes: obtaining a brightness value of each sampling point corresponding to image data of a transmission end on a basis of a three-dimensional mapping table; performing equal-brightness cutting on a three-dimensional gamut model of the transmission end and a three-dimensional gamut model of a display end separately on a basis of the brightness value of each sampling point to form a corresponding equal-brightness two-dimensional surface; and performing color mapping on a basis of the formed equal-brightness two-dimensional surface and outputting mapping data. Hence, during gamut mapping, brightness and tone are kept unchanged, precise matching of three-dimensional gamut mapping from a transmission gamut to a display gamut is realized, avoiding problems of image distortion or a display error or the like due to mapping mismatch between the transmission gamut and the display gamut.
