摘要：
This paper presents a color signal processing technique for use in single-chip CCD cameras that have CPUs employing SIMD (Single Instruction Multiple Data) instruction sets for signal processing. With it, processing time can be reduced to a half that of conventional techniques. Color space conversion is performed before color interpolation, rather than after, and as a vector operation; this reduces the number of required multiply-operations to 3 or 4, depending on the number of colors being used, as opposed to 9 for conventional 3 by 3 matrix processing.
