Abstract

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.
