Method and apparatus for efficiently calculating multiprimary color conversion matrices

摘要

A method for efficiently calculating multiprimary conversion matrices, the steps of said method comprising: calculating a plurality of conversion matrices, wherein each said conversion matrix converts source image data from its chromaticity triangle into a image point in a target color space; compressing said conversion matrices into smaller dimensioned matrices, wherein said smaller dimensioned matrices may convert source image data from its chromaticity triangle into a image point in a target color space; performing matrix multiplies with said smaller dimensioned matrices on said source image data; and multiplexing the results of said multiplies to create multiprimary values.
