GAMUT MAPPING

摘要

The present disclosure provides a gamut mapping method. In the gamut mapping method, a plurality of first color points of a first gamut of an image signal is mapped into a plurality of second color points of a second gamut. Each of the plurality of second color points is generated by multiplying each component value of the plurality of primary colors by a corresponding scaling factor. If at least one component value of the plurality of primary colors is zero, the larger a maximum component value of the plurality of primary colors is, the smaller the corresponding scaling factor is.

1. A gamut mapping method, comprising:
mapping a plurality of first color points of a first gamut of an image signal into a plurality of second color points of a second gamut, each of the plurality of first color points being composed of a plurality of primary colors, wherein each of the plurality of second color points is generated by multiplying each component value of the plurality of primary colors by a corresponding scaling factor; wherein if at least one component value of the plurality of primary colors is zero, the larger a maximum component value of the plurality of primary colors is, the smaller the corresponding scaling factor is.
