On a measurement method of configuration factor distributions with the help of an electronic still camera and a personal computer

Abstract In the field of daylighting design, the configuration factor is widely used as an index of the brightness because it is not affected by variation of illuminance. Therefore, the authors developed a method to measure the configuration factor distribution by using several still video images taken by the electronic still camera. More by this method, the configuration factor can be obtained more simply and exactly moreover in a shorter time. This paper describes the outline of this measurement method.
