谢谢科普,原来有这么多学问。自行去wikipedia研究了下,发现有如下这段:
请问CIE RA就是你提到的RA吗?根据下文,在5000K以下的光源中CIE RA特别会失真,所以业界提出了CRI R96 - 这和你说的R9是同一回事情吗?
CIE Ra's ability to predict color appearance has been criticized in favor of measures based on color appearance models, such as CIECAM02 and, for daylight simulators, the CIE Metamerism Index.[4] CRI is not a good indicator for use in visual assessment, especially for sources below 5000 kelvin (K).[5][6] A newer version of the CRI, R96, has been developed |
