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

Abstract

The invention discloses a color gamut mapping method, comprising: obtaining a first connecting line between the white point of the original color gamut and the original point of the original color gamut; obtaining the intersection point of the first connecting line and the original color gamut at the first mapping point in the target color gamut; obtain the second connecting line between the reference point in the original color gamut and the first mapping point; according to the white point, the reference point, the original point, the The intersection point and the second connecting line obtain the color coordinates of the second mapping point of the original point in the target color gamut; obtain the brightness value of the second mapping point according to the original point and the white point ; Acquiring the grayscale value of the second mapping point according to the color coordinates and the brightness value of the second mapping point. The invention also discloses a color gamut mapping component and a display device. The present invention automatically adjusts the performance of color points in the original color gamut in the target color gamut, without manual adjustment by professionals, avoiding subjective deviation, and achieving the consistency of color adjustment.
