我们确定了锥细胞和黑视蛋白亮度信号对人类亮度感知的贡献。在两种条件下估计了全视场Ganzfeld中呈现的四个窄带原色光的绝对亮度，即视锥亮度相等（186.7 - 1; 867.0 cd . m（-2））或黑视素亮度相等的（31.6 - 316.3黑视素cd . m（-2））。我们表明，亮度估计为每个主要的光遵循一个近似线性增加，增加锥或黑视蛋白亮度（对数单位），但不等同于与锥或黑视蛋白亮度的主要灯光。相反，亮度估计由视锥细胞和黑视蛋白信号传导之间的组合相互作用产生。与波长相关的系数的分析建模表示，黑视蛋白亮度与亮度大小正相关，并且视锥亮度具有两个贡献分量，一个是添加到黑视蛋白亮度，第二个是负的，这意味着适应过程。这些结果提供了一个新的框架，用于评估亮度感知的生理基础，并具有直接的实际应用，为节能光源的发展。(c)2018美国光学学会
We determined the contributions of cone and melanopsin luminance signaling to human brightness perception. The absolute brightness of four narrowband primary lights presented in a full-field Ganzfeld was estimated in two conditions, either cone luminance-equated (186.7 - 1; 867.0 cd . m(-2)) or melanopsin luminance-equated (31.6 - 316.3 melanopsin cd . m(-2)). We show that brightness estimations for each primary light follow an approximately linear increase with increasing cone or melanopsin luminance (in log units), but are not equivalent for primary lights equated with either cone or melanopsin luminance. Instead, brightness estimations result from a combined interaction between cone and melanopsin signaling. Analytical modeling with wavelength-dependent coefficients signifies that melanopsin luminance positively correlates with brightness magnitudes, and the cone luminance has two contribution components, one that is additive to melanopsin luminance and a second that is negative, implying an adaptation process. These results provide a new framework for evaluating the physiological basis of brightness perception and have direct practical applications for the development of energy-efficient light sources.
