Claim 1:
2. The color gamut mapping method as claimed in claim 1, wherein the step of obtaining the color coordinates of the 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 comprises:
obtaining a first distance from the reference point to the original point if the original point is not between the white point and the reference point;
obtaining a second distance from the reference point to the intersection point;
obtaining a first ratio of the first distance to the second distance;
obtaining the color coordinates of the second mapping point based on the first ratio and the second connection line; and
determining that the color coordinates of the second mapping point are the color coordinates of the original point if the original point is between the white point and the reference point.
