Claim 0:
1. A projector comprising:
a first light source including a first light-emitting region including a plurality of first light-emitting elements, the first light source being configured to emit a first light beam from the first light-emitting region;
a second light source including a second light-emitting region including a plurality of second light-emitting elements emitting light having a wavelength different from a wavelength of the first light-emitting element, the second light source being configured to emit a second light beam from the second light-emitting region;
an optical system configured to align traveling directions of the first light beam and the second light beam;
an optical modulation device configured to modulate the first light beam and the second light beam incident from the optical system in accordance with image information;
a projection optical device configured to project an image formed by the optical modulation device; and
a control unit configured to control a light emission intensity of each of the plurality of first light-emitting elements of the first light source and a light emission intensity of each of the plurality of second light-emitting elements of the second light source, wherein
the control unit changes a light-emitting position of the first light beam in the first light-emitting region to move a first illumination region of the first light beam on an image forming region of the optical modulation device,
changes a light-emitting position of the second light beam in the second light-emitting region to move a second illumination region of the second light beam, in the same direction as the first illumination region, on the image forming region of the optical modulation device, and
the first illumination region and the second illumination region do not overlap with each other on the image forming region.
