A Study on Simulation of Color Perception by Elderly People Employed Tritanomaly

Abstract

The ratio of elderly people whose age is more than 65 occupied in the entire population of Japan reached to 25% in 2013, and the ratio increases year by year. Human bodily changes by aging such as yellowing of lens, pupil size reduction and so on, and from this reason elderly people becomes to perceive deteriorated color than young people. From this point of view, a color reproduction method which simulates image that elderly people perceives on PC, and/or a color correction method to make the image that elderly people perceives close to the image that young people does have been proposed. However, in the results of artificial color perception test using SPP3 through the conventional color reproduction method by elderly people, there are a few mismatches with the results of actual color perception test for elderly people. In this report, to improve reproducibility of color perception by elderly people and make the results closer to the clinical data, we propose a new simulation method model that newly employed tritanomaly in conventional color perception model and verify its effectiveness.
