Screen-based color vision test for digital quantification of deutan color defects using a color-calibrated monitor

Display technologies are used in various industries. However, few studies on color vision testing using self-luminous displays are reported. In this study, a screen-based color vision test, termed the digital color vision test (DCVT), is developed on a color-calibrated monitor. A control bar is adjusted by the observer to build just noticeable chromatic difference ellipses in CIE u'v' chromaticity diagram, which indicate the capabilities of subjects' color visions. Ten color-normal observers and 13 deutan observers participated in the psychophysical experiments. The observers also performed the other two typical diagnostic tests (D-15 and anomaloscope). Results from the experiment using the adjustment psychophysical method for digital quantification of deutan color vision defects are presented. It is found that the diagnosis accuracy of the DCVT is approximately equivalent to those of D-15 and anomaloscope tests.
