COLOR GAMUT MAPPING METHOD, COLOR GAMUT MAPPING ASSEMBLY, AND DISPLAY DEVICE

摘要

A color gamut mapping method, a color gamut mapping assembly, and a display device. The color gamut mapping method comprises: obtaining a first connection line between a white point of an original color gamut and an original point of the original color gamut (S100); obtaining a first mapping point in a target color gamut of an intersection point of the first connection line and the original color gamut (S200); obtaining a second connection line between a reference point in the original color gamut and the first mapping point (S300); obtaining color coordinates of a second mapping point of the original point in the target color gamut according to the white point, the reference point, the original point, the intersection point, and the second connection line (S400); obtaining a brightness value of the second mapping point according to the original point and the white point (S500); and obtaining a grayscale value of the second mapping point according to the color coordinates and the brightness value of the second mapping point (S600).
