Photometry for brightness at any level including mesopic vision is described on the basis of the work conducted towards the development of a Commission Internationale de l'Eclairage (CIE) supplementary system of photometry in CIE technical committees. Several critical items in developing such a system are discussed: (1) how to scale brightness using the concept of equivalent luminance; (2) the basic vision model of brightness perception; (3) a description of the chromatic contribution to brightness at the photopic as well as at the mesopic level; (4) formulation of an adaptation coefficient for rod-cone interaction. A possible photometric model for brightness is described based on these considerations, together with a quantitative evaluation of the model using experimental data.
基于国际照明委员会（CIE）技术委员会为开发CIE补充光度系统所开展的工作，描述了包括中间视觉在内的任何亮度水平下的光度测量方法。讨论了开发这样一个系统中的几个关键问题：（1）如何使用等效亮度的概念来缩放亮度；（2）亮度感知的基本视觉模型；（3）明视觉和中间视觉水平下颜色对亮度贡献的描述；（4）杆体-锥体相互作用的适应系数公式。基于这些考虑因素，描述了一种可能的亮度光度模型，并使用实验数据对该模型进行了定量评估。
