Abstract: The reflection surface of a DMD is divided into a first area and a second area, causing the first area to display images while appropriately controlling the on and off states of the micromirrors within the second area on the basis of a prescribed control logic according to the on and off states of the micromirrors within the first area. Further, the DMD off-state light created in the first and second areas is caused to recurse to the DMD via a prescribed recycle optical system for the DMD off-state light, and only the second area in the reflection surface is intensively irradiated along a prescribed irradiation direction, thereby efficiently converting the DMD off-state light to the effective projection light.
