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 8):
The gamut mapping method for compressing the out-of-gamut area to the in-of-gamut area of  claim 6 , 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 further comprises:\n acquiring the first reference point P i  (C(P i ), L(P i )) of the target pixel point P in the small gamut area and a second reference point P s  when the target pixel point P is located outside the small gamut area, wherein P s  is a connection point of an extending line in a border of the large gamut area, the extending line connects the target pixel point P with P C , 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  is a vertical connection point of P C  in the vertical axis, P C  is a vertical connection point of the target pixel point P in a border of the small gamut area, and L F  is a vertical connection point of P C  in the vertical axis; and determining a coordinate value P\u2032 (C p\u2032 , L p\u2032 ) in the small gamut area according to the second reference point P s , wherein L p\u2032 =L(L F ), and C p\u2032 =(|PP C |+|P C P i |)*|P i P C |)/(|P S P C |+|P C P i |)+C(P i ).
