Abstract
Light emitted from a lamp enters a color wheel having a region for allowing a predetermined color to pass therethrough, is reflected on a mirror, and enters a DMD. After this, the light is reflected by the DMD and enters a color sensor, which then detects the color of the transmitting light. A projection apparatus automatically synchronizes the control on the rotation of the color wheel and the control on the proceeding direction of the transmitting light by the DMD, based on a color time-division pattern of the transmitting light detected by the color sensor.
