Abstract:

It is known that the lenticular transmittance of elderly people is lower than that of young people. Especially, it is remarkable for short wavelength lights. Therefore blue-tinged colors become darker comparing with the other colors in the field of vision of elderly people. In this paper, in order to improve the visibilities of blue-tinged colors in the elderly vision, the data-dependent gamma correction is proposed. Concretely, RGB components are converted by the gamma correction with a gamma which is set according to the hue, saturation and lightness contrast in each pixel. Through the experiments using some digital color images, the effectiveness of the proposed method is verified.
