[BRIGHTNESS CONTROL]
The projector is equipped with a luminance sensor to measure brightness and color of the lamp, and corrects
brightness and color of the projected image according to the changes in brightness and color of the lamp.
By using this function, it is possible to reduce the changes of brightness and color of the entire multiple screen, or
hold down the differences of the brightness and color, making it possible to maintain uniformity when constructing
multiple screen using multiple projectors.
