In order to solve the distortion problem of color signal in cross media reproduction process
a gamut mapping algorithm based on spherical coordinates and triangular interpolation was proposed.Firstly
the algorithm chooses the boundary color samples of target gamut as the triangular interpolation nodes.Secondly
three optimal interpolation nodes are selected through a pre-search process.Finally
the algorithm calculates the correspondent gamut boundary point of the mapping color by triangular interpolation.The experimental results demonstrate that the algorithm has good calculation precision and efficiency
and can be used in the color mapping process of different color devices and images.
