Development of Portable Color Discriminagion System for Visually and Color Blind

Accuracy Improvement fo Photoelectric Colorimeter by Automated Calibration System

Abstract

The visually handicapped persons are often inconvenient to distinguish the color in the daily life. We have developed the portable color identification equipment. At first, it measures the surface color in the same way as the photoelectric colorimeter. Next, it translates the measured RGB data into the color name so that we can image the color easily. The color name is expressed by adding a modifier about lightness and chrome to 13 basic color names. Finally, it informs the color name by the voice for the visually handicapped persons. This equipment contains automated calibration system in order to make a measurement result be steady. The effectiveness of this system was shown by the experiment under various conditions of a temperature and illuminants.
