Abstract:
The present disclosure provides a gamut mapping method including acquiring a first coordinate value of a target pixel point P in a Lab color space according lo digital values of the target pixel point P in a large gamut area; determining a hue plane in which the target pixel point P is located, and determining (H, C, L) of the target pixel point P; mapping the target pixel point P to the small gamut area to acquire a second coordinate value of a mapped pixel point P 1  in the Lab color space; and acquiring mapped digital values of the mopped pixel point P 1  in the small gamut area.

Claim (Index 6):
The gamut mapping method for compressing the out-of-gamut area to the in-of-gamut area of  claim 5 , wherein the step of mapping the target pixel point P to the small gamut area according to (H, C, L) to acquire the second coordinate value of the mapped pixel point P 1  in the Lab color space comprises:\n determining that the target pixel point P is located outside the small gamut area or inside the small gamut area according to values of C and L; acquiring a first reference point P i  (C(P i ), L(P i )) of the target pixel point P in the small gamut area when the target pixel point P is located inside the small gamut area, wherein C(P i )=\u03b1C(P C ), L(P i )=L(L F ), P C  is a vertical connection point of the target pixel point P in a border of the small gamut area, L F  a vertical connection point of P C  in the vertical axis, \u03b1 is a preset adjusting coefficient. \u03b1\u2208[0, 1]; determining that the target pixel point P is located in a left side of the first reference point P i  or a right side; and serving the first coordinate value of the target pixel point P as the second coordinate value of the mapped pixel point P 1  in the Lab color space when the target pixel point P is located in the left side of the first reference point P i .
