Research on Spatial Gamut Mapping from Source Device to Destination Device

Different device media can be used to display and output colors in the process of color information transmission. It is difficult to achieve high-fidelity reproduction of color information due to the different color reproduction ranges of different devices. This paper designs a gamut mapping algorithm from the source device to the destination device. Based on the design principle of gamut mapping algorithm, the LCUSP algorithm is optimized and improved, and a comprehensive gamut mapping algorithm with both lightness and chroma compression is selected for experiments. The experimental results show that the chroma information of source gamut dark tone area is maintained in the same hue angle plane, which makes up for the poor reproduction ability of the dark tone part of the output device, and the overall reproduction degree is excellent.
