PROJECTOR AND HEAD-UP DISPLAY DEVICE

摘要

A projector includes: a laser light generating unit that emits laser light including image information; a laser light scanning unit that scans the laser light emitted by the laser light generating unit at a predetermined scan angle to project an image on a transparent display plate; and a scan control unit that sets a scan driving voltage, which determines the scan angle, according to an atmospheric pressure of an area in which the laser light scanning unit is disposed and supplies the scan driving voltage to the laser light scanning unit to control fluctuations in the scan angle.
