色差公式的发展史和最新CIE色差公式

Developing History of Color Difference Formulae and Last CIE Color Difference Formula

１９７６年是本世纪来现代色度学发展的分水岭．本文评述了１９７６年之前色差公式的开发成果及其实验基础，重点介绍１９７６年以来的ＣＭＣ（ｌ：ｃ）色基公式和ＣＩＥＴＣＩ－２９推荐的ＣＩＥ１９９４（）色差模型及色差公式．ＣＩＥＴＣ１－２９依据一项定期改进战略，在ＣＩＥＬＡＢ系统的基础上，应用加权函数校正空间距离的不均匀性，采用参量因子校正知觉色差的参量效应，从而保证了ＣＩＥＬＡＢ模型为近似均匀色空间，实现了仅用一个容基数值裁定色匹配的可接受性．

To Survey development of modern colorimetry for half century and to divide line by1976, this peper roviewe developed achievements of color difference formulae before 1976 and theirexperimental bases,mainly introduces CMC(l:c) Color difference formula after 1976 and CIE1994 ()Color difference model,color difference formula recommended by CIETC 1-29. On the basis of CIE LAB system and a periodic improvement stratagy,using weightingfunctions correct the nonuniformity of color space distances, using parametric factors Correct parametric effect of color difference perceptiont therfore it retains the CIE LAB model as an approximately uniform color space.It has achieved to judge acceptability of colcr match with only humerical tolerance.
