METHOD FOR INCREASING THE INTENSITY OF A PIXEL AREA IN A PROJECTED IMAGE BY ALTERING THE SCANNING SPEED OF A LASER PROJECTOR

摘要

A method of projecting an image onto a viewing surface (64) uses scanning projector, such as a laser-beam-steering pico projector (46), which scans a laser beam across the viewing surface. Each pixel area (62) on the viewing surface which is included within images defined by a high intensity display digital video data, and each pixel area on the viewing surface which is included within images defined by a low intensity display digital video data are scanned. The projector beam (70) illuminates each pixel area on the viewing surface which is included within images defined by the high intensity display digital video data for a greater period of time than is spent illuminating each pixel area on the viewing surface which is included within images defined by other digital video data.
