Simulating Vision of Older People for the Design of On-board Visual Displays

摘要

In this paper, we propose a new approach to designing visual displays for older people based on a human vision model. We have developed a system to simulate a human vision using image processing techniques. The model is represented by three vision properties; the contrast sensitivity of eyes, the spectral transmittance of crystalline lens and the accommodation. Which are found in the visual science literature. In order to compensate deteriorations of human vision with age, the image enhancements by sharpening edges and by changing color balance are used.
