EVALUATION OF BRIGHTNESS ON HUMAN FACE WITH A WINDOW IN THE BACK

Evaluation of brightness on a human face was investigated under silhouette phenomenon. There were few reports about silhouette phenomena assuming in a residential space. Therefore, we conducted an experimental study with 11 tests by using a 1/10 room model. The brightness on a human face by test's evaluation was well predicted by using brightness conversion technique which was proposed by author's group, even though it was not good correlations with conventional methods using facial illuminance and facial brightness.
