Color Appearance of a Scene under Automotive Headlamp Light 1999-01-0701
It is believed that the driver's color appearance in his visual field illuminated by the headlamps at night is similar to the mesopic vision. In this study, therefore, we attempted to experimentally clarify how colors are appeared when the headlamps are turned on at night.
Processing the results of this experiment with a color engineering technology, we attempted to reproduce the color appearance of scene during nighttime driving.
The purpose of this study was to reproduct the appearance of colors during nighttime driving on the basis of ones in the daytime. By this reproduction, the night driving safety and the visibility of the headlamp evaluation are expected to be improved.
