Abstract
A projector includes a light source, a light modulator that has an image drawing region where an image is drawable and modulates light emitted from the light source by using an image drawn in the image drawing region, and a projection system that includes a projection lens and projects image light modulated by the light modulator. The projector further includes a lens shift mechanism that moves the projection lens and a control section that controls the image drawing performed by the light modulator, and the control section provides, based on the position of the projection lens, the image drawing region of the light modulator with a suppression region where the amount of the image light is suppressed.
