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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
