The application of digital imaging to color measurement is more and extensive, which also provides new ideas for gemology. In this paper, the single-factor experiment method orthogonal design are used study influence parameters system (DIS) on gem measurement. Among them, illuminance has most significant impact results, followed by exposure time, change distance an insignificant results; through range analysis variance, suitable red jadeite 1600 lx, 12,500 μs, 25 cm.
