基于显示器特性的彩色对比敏感度测试
Chromatic contrast sensitivity measurement based on the characteristics of display equipment
摘要
Abstract
In order to obtain the specific characteristics of human visual system and support engineering design and ergonomic evaluation directly,a kind of chromatic contrast sensitivity was defined accord-ing to RGB color space which was widely used by display equipment.First,a threshold measurement method of chromatic contrast sensitivity was generated.Then 12 participants’data which contained two time periods,three variables and ten spatial frequencies were collected.Finally,Pearsontest anal-ysis was used to measure the correlation of results in two time periods,and chromatic contrast sensi-tivity curve of three variables (R,G,B)was drawn.The analysis results showed that measuring re-sults in two time periods were significantly correlated.The tendency of three variables’contrast sen-sitivity curves was similar and the threshold significantly increased when the spatial frequency came to 0.1 and 0.2 cycle/degree.The threshold value of variable R was higher than that of variable G and B on the whole.The reliability of measurement method was verified besides the threshold was high at extremely low spatial frequency and the participants were weak in distinguishing minor differences of red.关键词
