Abstract:
1. A projector comprising: a plurality of laser beam generation portions emitting laser beams having substantially identical lasing wavelengths; a projection portion projecting an image onto an arbitrary projection area by scanning the laser beams emitted from the plurality of laser beam generation portions respectively; and a control portion controlling generation timings of the laser beams emitted from the plurality of laser beam generation portions respectively; wherein the projector that deviates optical axes of the laser beams emitted from the plurality of laser beam generation portions respectively to be irradiated with the laser beams emitted from the plurality of laser beam generation portions respectively on different positions of the projection portion, and the control portion that deviates the timings when the plurality of laser beam generation portions emit the laser beams from each other in response to the quantities of deviation of the optical axes of the laser beams emitted from the plurality of laser beam generation portions respectively to substantially coincide the image projected onto the arbitrary projection area with each other when the image is projected by scanning the laser beams emitted from the plurality of laser beam generation portions whose optical axes have been deviated from each other.
