Outline of Final Research Achievements

In order to apply CIE mesopic photometry to practical road lighting, we conducted the following reasearch. (1) We defined adaptation luminance in the whole visual field. Especially, we found that eyes of human beings were adapted to local luminance. (2) We improved the current CIE mesopic photometry so that we can apply it to the whole visual field. (3) We developed an image processing system for mesopic photometry which can calculate mesopic luminance distributions based on luminance maps taken by cameras.
