摘要： 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.

摘要： A projector projects image light generated by an image generation unit, as an enlarged image via a projection system. The incident position of the image light on the projection system is moved by a lens shift mechanism. The projection system forms an intermediate image in the course of the optical path. A light-shielding mask is provided at an image forming position of the intermediate image. A light-shielding area by the light-shielding mask includes an area that does not overlap the intermediate image within a range of an effective image forming area at the image forming position of the intermediate image. For example, the light-shielding area is an area on the side opposite to the side to which the intermediate image is shifted, of the effective image forming area.
