Color space conversion models from RGB to CIEXYZ were established with polynomial regression algorithm. T he conversion was realized wit h pro2 gramming and the accuracy of the model was analyzed. ey words: color space; RGB- CIEXYZ conversion; polynomial regression , , , R, G, B , , , ; [1] , , [ 2] , , ( RGB )RGB , RGB 1.2 CIEXYZ XYZ LAB, RGB CIE 1931 RGB [ 2] ( CRT) CMYK () , , , , RGB CIEXYZ , Phot oShop , RGB CIEXYZ , , 1931 [ 3] , CIE XYZ CIEXYZ , 1 , 1. 1 RGB : 2 RGB CIEXYZ 3 , R, G, B 3 , RGB
