Abstract

A color gamut mapping method and apparatus, includes obtaining a to-be-processed image, obtaining lightness and chroma information of a target color gamut, and mapping a lightness value and a chroma value of a pixel in the to-be-processed image to obtain a processed image corresponding to the target color gamut, where a pixel in the processed image has a mapped lightness value and a mapped chroma value, and the mapped lightness value and the mapped chroma value are obtained by mapping the lightness value and the chroma value of the pixel in a color gamut of the to-be-processed image to the target color gamut using a point with a minimum lightness value in the target color gamut as a mapping end point.
