The objective of this study is to test the luminous efficiency functions V(lambda), V'(lambda), V(10)(lambda) and their linear combinations on the basis of a data set gained from a simulated mesopic night-time driving experiment. Another aim is to provide 'real-world' data for the 'X framework' or 'linear combination model', and to find out its limits in a practical situation. Human performance was measured by the reaction time method. Results show that the single parameter of the linear combination of photopic and scotopic luminous efficiency functions can be determined analytically with little variation for a given mesopic background luminance level and a given visual target colour, but the computation leads to considerable deviations comparing all three target colours (red, green and blue) used in the experiment. The conclusion for the given experimental conditions is that the single parameter of the linear combination model has an increasing deviation for lower background luminance levels.
本研究的目的是基于从模拟的中间视觉夜间驾驶实验获得的数据集，测试明视觉效率函数V(λ)、V'(λ)、V(10)(λ)及其线性组合。另一个目的是为“X框架”或“线性组合模型”提供“真实世界”的数据，并找出其在实际情况下的局限性。通过反应时间法测量人类表现。结果表明，对于给定的中间视觉背景亮度水平和给定的视觉目标颜色，明视觉和暗视觉发光效率函数线性组合的单参数可以通过分析确定，变化很小，但与实验中使用的所有三种目标颜色（红色、绿色和蓝色）相比，计算会导致相当大的偏差。对于给定的实验条件，结论是线性组合模型的单参数在较低背景亮度水平下偏差会增大。
