| 摘 要： | 目的]探讨Lab色度系统与人眼视觉感受在评价黑白差异中的异同。方法]采用Lab色度系统光谱光度计测量成对纸片黑白度差异(以L值差值表示),通过正常人群对每对纸片颜色深浅判别的正确率,分析Lab色度系统与人眼视觉感受的关系。结果]L值差值在0~7时,人眼分辨正确率为20.00%~98.57%,男性较女性高,<40岁人群较>40岁人群高;当L值差值≥1时,67.14%的人视觉感受与Lab色度系统结果一致。结论]Lab色度系统评价黑白差异时只有其差值≥1时,才能应用于美白化妆品的评价。

| Abstract: | Objective]To study the relationship between Lab color system and human color vision on black-white discrimination.Methods]The difference of L value was used to quantify black-white discrimination in a pair of paper sheets using spectrophotometer. The discrimination also was determined by human eye vision.Results]When the L value differences are among 0~7,the accuracy of human eyes were among 20.00%~98.57%;the accuracy of male was higher than that of female; when the L value differences were higher than 1,67.14% of people could discriminate them correctly.Conclusion]Only when the L value difference was higher than 1,could the Lab color system be applied in assessment of cosmetic. |
