Abstract
A composite laser beam is swept as a pattern of scan lines on a projection surface, and selected pixels arranged along each scan line are illuminated to project an image of high quality and in color. A data frequency of a video signal supplied by a host is matched to a scan frequency of a scan mirror to reduce the amount of buffer memory required and to make the projected image brighter and more uniform in brightness.
