Abstract

A projector that projects image light on a projection surface and including a light modulator that modulates light emitted from a light source to form the image light, an optical path deflecting section that changes the projection direction of the image light modulated with the light modulator, a projection system that projects the image light outputted from the optical path deflecting section on the projection surface, a vibration detecting section that detects vibration acting on the projector, and an optical path deflection controlling section that controls the amount of change in the projection direction deflected by the optical path deflecting section based on the vibration detected by the vibration detection section.
