Abstract:
A projector including a discharge tube as a light source includes a light source driver that supplies the discharge tube with electric power and an electric power control portion that controls the level of the electric power with which the light source driver supplies the discharge tube to perform a normal mode in which the light source driver supplies electric power of a predetermined electric power level and a power saving mode in which the light source driver supplies electric power of a power saving level lower than the predetermined electric power level. The power saving mode is a mode in which light emission from the discharge tube can be maintained.
