It is known that the lenticular transmittance of elderly person is lower than that of young person. This low lenticular transmittance property causes the brightness decrease of the visual field of the elderly person. In this report, the lightness transform method of the image for the elderly person is proposed. In the proposed method, the colors, which are hard to see for the elderly person, are transformed into the colors, which are easy to see, by adding them the lightness contrast. The effectiveness of the proposed method is verified by some experiments.
