| 摘 要： | 关于照相物镜色贡献指数的国际标准于1983年公布。但是,关于色贡献指数(ISO/CCI)的容限仍保留在附录中,并以建议的形式给出。本文从色度学基本公式出发,对相应于容限范围内六个边缘点的照相物镜,计算了它们摄影效果的色度坐标。同时计算了它们和ISO标准照相物镜的摄影效果在均匀颜色空间的色差值。据此讨论了该容限的合理性,并提出把容限范围划分成两个区域的建议。

| Abstract: | In this paper, chromaticity co-ordinates of photographic effect of camera lenses corresponding to the six points, which limited the tolerance of ISO/001, is calculated by means of the basic formulae of colorimetry. The color difference of photographic, effects between the lenses according with the six points and the ISO standard camera lens is computed by using the OIE 1964 color difference formulae. According to these results, the rationality of the tolerance of ISO/001 is discussed and the proposal for dividing the telerance of ISO/CCI into two regions is presented. |
