Abstract
A projector that projects image light on a projection surface includes a light modulator that modulates light emitted from a light source based on image information to form the image light, a projection system that projects the image light modulated by the light modulator on the projection surface, a light modulator moving section that changes the position of the light modulator, a vibration detecting section that detects vibration acting on the projector, and a controller that causes the light modulator moving section to change the position of the light modulator based on the vibration detected by the vibration detecting section.
