We have investigated a computer simulation method of color perception by elderly people. However, the previous method has two problems to be considered. That is, the luminescence spectrum of the display used in the experiments is not sufficiently examined, and there are some mismatches between the results of the artificial test through this simulator and the ones by the clinical test for elderly people using SPP color perception test. To improve this simulation method totally, in this work, (i) we utilize the actual luminescence emission spectrum measured for the LCD display used in the experiments. Also, (ii) we relax the color constancy hypothesis so that the lenticular yellowing changes not only luminosity but also chromaticity in color perception. Experimental results suggest that the accuracy of the simulator is fairly improved by these modifications.
