Abstract
A projector includes a first light source that emits a first light beam from a first light-emitting region including first light-emitting elements, and a second light source that emits a second light beam from a second light-emitting region including second light-emitting elements emitting light. Projector includes optical system that aligns traveling directions of first and second light beams, optical modulation device that adjusts first and second light beams based on image information, projection optical device, and control unit. The control unit changes a light-emitting position of the first light beam in the first light-emitting region to move an illumination region on an image forming region of the optical modulation device, and changes a light-emitting position of the second light beam in the second light-emitting region to move a second illumination region on the image forming region of the optical modulation device in the same direction as the first illumination region.
