摘要
为实现在实验"中期"内小范围精确控制CRT显示器颜色,提出了一种新的小范围内CRT色彩空间转换方法,并通过实验验证,在"中期"内控制色度Y、L*、a*、b*的精度分别达到0.1711、0.2782、0.1108、0.1134,色差可控制精度达到0.3543ΔE*ab,比现有的LUT方法和GOG模型方法更精确,且用这种方法建立彩色显示器颜色查找表时,只需要测量小范围各单色通道单独显示和三通道共同显示颜色的三刺激值,不需要求解复杂的方程。
CRT monitor controlled by the computer has been applied widely in the color and vision research. However, precision of controlling color is requested higher and higher in some fields and some experiments are needful to be finished in the medium term, therefor color characteristic of CRT monitor is needed to research further. So far, precision of characteristic isn＇t still good because of disturbance among the channels though there are some methods to settle it. A new method of CRT color space conversion in small range was put forward. The experiment showed that precision of controlling color Y,L^＋ ,a^＋ ,b^＋ in the medium term can arrive to 0. 171 1,0. 278 2,0. 110 8,0. 113 4, and precision of controlling chromatic aberration can arrive to 0. 354 3 △E^＋ ab. This precision is higher than that by LUT and GOG method, and when founding LUT of color CRT monitor with the method, small range＇ tristimulus value of three channels displaying by themselves and together are merely needed to be measured, without settling the complicated equations.
