To realize a suitable visual environment in the room in which much information is transmitted using an overhead projector, it is important to identify the conditions of three visual factors (size, background luminance and luminance contrast) of a projected picture under a given situation. The effects of the condition of an original picture, a projector and operation on the characteristics of the projected picture are examined through an experiment in an actual situation. According to results of the experiment, some variables of a projector performance useful for deriving the size of a projected picture and the illuminance on the screen are specified. The calculation formulae to estimate three visual factors of a projected picture are presented. These formulae are composed of instrumental performance variables and the conditions of original picture, lighting and operation.
