Claim 5:
6. The projector according to claim 1, further comprising:
a third light source including a third light-emitting region including a plurality of third light-emitting elements emitting light having a wavelength different from the wavelengths of the first light-emitting element and the second light-emitting element, the third light source being configured to emit a third light beam from the third light-emitting region, wherein
the optical system aligns a traveling direction of the third light beam with the traveling direction of the first light beam and the second light beam,
the optical modulation device modulates the first light beam, the second light beam, and the third light beam incident from the optical system based on image information,
the control unit controls a light emission intensity of each of the plurality of third light-emitting elements, and changes a light-emitting position of the third light beam in the third light-emitting region to move a third illumination region of the third light beam, in the same direction as the first illumination region and the second illumination region, on the image forming region of the optical modulation device, and
the first illumination region, the second illumination region, and the third illumination region illuminate different positions of the optical modulation device, respectively.
