一个物体的颜色似乎是不同的老年人和年轻人。这是因为人类的视觉特征随年龄而变化。通常，老年人的晶状体透镜的光谱透射率低于年轻人的。低光谱透射率降低了视野的亮度。这种现象影响了人类视觉感知中图像的颜色外观。本文提出了一种亮度变换的方法来改善老年人图像的色彩外观。在所提出的方法中，通过添加亮度对比度，将老年人难以看到的颜色转换为容易看到的颜色。所提出的方法的性能在使用数字图像的实验中得到证实。
The color of an object appears to be different for elderly and young persons. This is because human visual features vary with on age. In general, the spectral transmittance of the crystalline lens of an elderly person is lower than that of a young person. The low spectral transmittance decreases the brightness of the visual field. This phenomenon affects the color appearance of an image in human visual perception. In this paper, a lightness transform method is proposed to improve the color appearance of images for elderly persons. In the proposed method, colors that are difficult for an elderly person to see are transformed into colors that are easy to see by adding lightness contrast. The performance of the proposed method is confirmed in experiments using digital images.
