ABSTRACT:
A projector changes stepwise electric energy supplied to a light source based on temperature information which is detected by a temperature sensor. The temperature sensor detects the temperature of components of an optical engine or an ambient air temperature. A lamp output control circuit changes stepwise the electric energy supplied to the light source based on the temperature information detected by the temperature sensor.
