抽象的。本文报告了在给定白色亮度级别（从五个候选值（100、200、500、1000 和2000 cd / m2)，通过心理物理实验。这项工作表明，随着显示器最大白色亮度的增加，良好可视性的亮度水平也会增加。显示器亮度的白色亮度依赖性是由于人类视觉系统适应最大白色亮度并根据它评估显示器的亮度而引起的。根据实验结果，提出了各种照度条件下的合适亮度区域。适当的亮度区域随显示器的最大白色亮度而变化。这可以理解为意味着在给定照明条件下不存在绝对亮度水平。为了解决这个问题，提出了一种新方法，通过考虑可见度和功耗来确定最佳亮度水平。据报道，通过所提出的方法，室内使用的最佳最大亮度介于 200 至 500cd / m2 之间（低于 500 lx）。这些结果得到了视力正常的年轻人的验证。
Abstract. This paper reports display luminance levels for good visibility under nine ambient illuminance conditions (50, 100, 200, 500, 1000, 2000, 5000, 10,000, and 20,000 lx) for a given white luminance level, chosen from five candidates (100, 200, 500, 1000, and 2000 cd / m2), through a psychophysical experiment. This work reveals that the luminance levels for good visibility increase as the maximum white luminance of the display increases. The white luminance dependency of display luminance is caused by the fact that the human visual system adapts to the maximum white luminance and evaluates the brightness of the display based on it. Based on the experimental results, an appropriate luminance zone under various illuminance conditions is proposed. The appropriate luminance zone varies with the maximum white luminance of the displays. This may be understood to mean that there is no absolute luminance level under a given lighting condition. To solve this issue, a new method is proposed to determine optimum luminance levels by considering both visibility and power consumption. By the proposed method, it is reported that the optimum maximum luminance lies between 200 and 500 cd / m2 for indoor use (below 500 lx). These results were verified by young adults with normal vision.
