过去进行的研究，以确定是否光源的光谱功率分布影响面部识别导致了混合的结果。其中一个原因可能是，不同的研究提出了不同的任务难度水平，这是一个功能的目标大小，观察时间和类型的程序。本文提出了两个人脸识别实验进行匹配和识别程序，探讨任务难度定义的观察时间和目标亮度。据证实，识别比匹配更困难。任务难度（亮度和持续时间）和识别概率之间的关系被发现，这使得亮度被确定为一个给定的概率。
Past studies carried out to determine whether the spectral power distribution of a light source affects facial recognition have led to mixed results. One reason for this could be that different studies presented different levels of task difficulty, this being a function of target size, observation duration and type of procedure. This paper presents two facial recognition experiments carried out using matching and identification procedures to explore task difficulty as defined by observation duration and target luminance. It was confirmed that identification is more difficult than matching. A relationship between task difficulty (luminance and duration) and recognition probability was found and this allows the luminance to be determined for a given probability.
