Evaluation of Visual Environment Considering Spectral and Luminance Distribution

通过主观实验确定不同波长目标在周边视觉下的可见度差异，以及被试所适应的亮度水平和发光颜色对可见度的影响。结果表明，在各种实验条件下，所有受试者都能感知和判断暴露在视野中心的目标的颜色。被试所适应的亮度或发光颜色的变化对中心视觉上发光颜色的可见性水平没有显著影响。当目标与被试视野的偏心角度大于40度时，能正确判断目标颜色的被试比例急剧下降。还可以看出，在2 lx条件下进行评价的情况下，青年被试能够判断出蓝色发光颜色的比例高于绿色。

Subjective experiment was conducted to identify the difference in visibility of the target with different wavelength at peripheral vision and the effects on visibility of luminance level and luminous colour to which the subjects adapted.As results, all subjects could perceive and judge the colour of the target exposed at the centre of the visual field under every experimental conditions. No significant effects of the change in luminance or luminous colour to which the subjects adapted were found on the visibility level of luminous colour at central vision. In the case when the eccentric angle of the target from the subjects' vision became larger than 40 degree, the percentage of the subjects who could judge the colour of the target correctly decreased dramatically. It also could be seen that the percentage of the young subjects who could judge the luminous colour of blue was higher than that of green in the case when they evaluated under the conditions of 2 lx.
