Abstract:
A projector includes a dimming device that moves a light-shielding member for shielding light to adjust the amount of light emitted from a light source, a housing that accommodates the dimming device, a temperature detection section that detects an internal temperature of the housing, and a control section that controls an adjustment state of the amount of light through the dimming device. The control section starts a control of the dimming device when the temperature detected by the temperature detection section is set to equal to or higher than a predetermined temperature.
