Color gamut mapping method, color gamut mapping assembly and display device

Abstract

The invention discloses a color gamut mapping method. The method comprises the following steps: acquiring a first connecting line between a white point of an original color gamut and an original pointof the original color gamut; obtaining a first mapping point of an intersection point of the first connecting line and the original color gamut in a target color gamut; acquiring a second connectingline between a reference point in the original color gamut and the first mapping point; obtaining color coordinates of a second mapping point of the original point in the target color gamut accordingto the white point, the reference point, the original point, the intersection point and the second connecting line; obtaining a brightness value of the second mapping point according to the original point and the white point; and obtaining a gray-scale value of the second mapping point according to the color coordinate and the brightness value of the second mapping point. The invention further discloses a color gamut mapping assembly and a display device. By automatically adjusting the expression of the color points in the original color gamut in the target color gamut, manual adjustment by professionals is not needed, subjective deviation is avoided, and color adjustment consistency is achieved.
