| Abstract(in English) | It is known that the lenticular transmittance of elderly person is lower than that of young person. It is remarkable in a short wavelength in particular. In this report, in order to realize the visibility improvement of blue-tinged colors, the lightness conversion method by $gamma$ correction is proposed. Concretely, an RGB value is converted by the $gamma$ correction with $gamma$ which is set according to the hue, saturation and lightness of each pixel. The effectiveness of the proposed method is verified by some experiments. |
