摘要
VDT的亮度对比度和屏面亮度在对操作者视觉功能的影响中,存在着交互作用。VDT的最佳对比度和适宜对比度范围随屏面亮度水平而变化,提高屏面亮度可以使最佳对比度值和适宜对比度范围向低对比度端偏移。评价VDT显示质量,主观评价法具有与作业绩效指标同样的价值。
There are interactions in the effects of VDT luminance contrast and screen luminance on operator's visual performance. The range of both optimal or proper contrast is the function of the level of background luminance on screen. Increasing screen luminance results in a shift from the optimal and proper contrasts towards the low contrast. Subjective evaluation method has the same validity as the performance index in assessing the quality of VDT display.
