摘要：We propose a color reproduction model concerned for aging a crystalline lens and a method to correct the color schemes on data contents that are imperceptible to the elderly. We assumed that the spectral distribution of the contents is defined with a certain LCD spectrum. Our proposed color reproduction model uses the optical density function of crystalline lenses formatted by Pokorny et al. First, we analyze the effect of aging on color perception using this model. We show that the difference in color perception between the young and the elderly depends on color lightness and hue. Second we show that the spectral compensation of all the screen colors that decrease the spectral transmittance of aged crystalline lenses causes an increase in imperceptibility. Finally, a method using a color palette is proposed for changing the colors in regions that are identified to be imperceptible to the elderly. From these studies, an evaluation and correction support system of color schemes has been prototyped.
