Abstract
A liquid crystal projector provided with a cooling fan comprises a temperature sensor for detecting the internal temperature of the liquid crystal projector, an air pressure sensor for detecting outside air pressure, and a control device for controlling the number of revolutions of the cooling fan on the basis of the temperature detected by the temperature sensor and the outside air pressure detected by the air pressure sensor.
