COLOR MATCHING CONSIDERATION ON THE EFFECT OF IPRGC FOR COLOR REPRODUCTION ON DISPLAY DEVICE

At the beginning of this century, intrinsically photoreceptive retinal ganglion cells (ipRGCs), new photoreceptors different from cones and rods, were discovered. The aim of this study was to experimentally verify the influence of ipRGCs on the colour reproduction of a display. In the experiment, we performed perceptual colour matching between colour patches and displays. Although colorimetric reproduction of the colour patch was used for the initial image of the display, the colour matching results were largely out of colorimetric colour reproduction. Since this result suggests that ipRGCs may affect colour reproduction of displays, a correction equation that accounts for the influence of ipRGCs was derived. Applying this correction formula improved the results. It is considered possible to accurately display the colour of a real object on a display using a correction equation that accounts for the effect of ipRGCs.
