摘　　要：中间视觉状态下由于视锥细胞和视杆细胞同时作用,且其响应特性随适应亮度不同而改变,因而中间视觉的光度计算分析一般比较复杂。我们在此前的研究中建立了一套基于人眼神经通路的视觉计算模型,理论上可实现对明视觉、暗视觉和中间视觉各种光环境场景下的视觉感知分析。本文以五种不同颜色LED为视目标构建了实验场景,计算分析了其在中间视觉条件下的视感知对比度,并与国际照明委员会(CIE)推荐模型的计算结果进行了比对分析,初步验证了该视网膜模型在中间视觉光度计算中应用的可行性。In the state of mesopic vision,since the cone and rod cells act at the same time,and their response characteristics change with the adaptation luminance,the photometric analysis of mesopic vision are generally complex.In our previous paper,we have developed a retinal computing model based on human neural pathway,which can theoretically realize the visual perception analysis of photopic,scotopic and mesopic vision in various lighting environments.In this paper,five different colors LED are used as the visual tasks to build the experimental scene.The mesopic luminance contrast are then calculated and compared with the results of CIE recommended model.The application feasibility of the retinal model in the calculation of mesopic vision is preliminarily verified.
