研究了彩色背景对亮度对比敏感度函数的影响。从CIE 17色中心中选取了灰、橙子、黄绿三种背景色。这些颜色的平均亮度大致相等。我们使用CRT显示器显示矩形条纹。每个矩形条纹有6个空间频率（0.4，1，2，3.5，7，14cpd），实验采用极限法，视力正常，视力测验均在1.0以上的5名观察者参加。实验结果表明，彩色背景下的亮度对比灵敏度低于灰色背景下的亮度对比灵敏度。拟合结果表明，Movshon模型的拟合效果优于Barten模型，尤其是对彩色背景的拟合效果更好。两种模型在高空间频率部分都存在偏差。
The effect of chromatic background on luminance contrast-sensitivity function (CSF) is studied. We selected three background-grey, orange and yellow-green from CIE 17 color center. The mean luminance of these colors is approximately equal. We use CRT monitor display the rectangular stripe. Every rectangular stripe has six spatial frequencies (0.4, 1, 2, 3.5,7 and 14cpd) .The method of limits is used in the experiment, 5 observers, who have normal vision and test of vision is all over 1.0, participated in the experiment. The results of experiment show that the luminance contrast sensitivity on chromatic background is lower than the luminance contrast sensitivity under grey background. Fitting results show that Movshon model is better than Barten model, especially for the chromatic background. Both of the models have deviation in the high spatial frequency part.
