ON A MEASUREMENT METHOD OF CONFIGURATION FACTOR DISTRIBUTIONS WITH THE HELP OF AN ELECTRONIC STILL CAMERA AND A PERSONAL-COMPUTER

In the field of daylighting design, the configuration factor is widely used as an index of the brightness because it is not affected by vari ation of illuminance, Therefore, the authors developed a method to mea sure the configuration factor distribution by using several still vide o images taken by the electronic still camera. More by this method, th e configuration factor can be obtained more simply and exactly moreove r in a shorter time, This paper describes the outline of this measurem ent method.
