<P>PROBLEM TO BE SOLVED: To provide a projection system employing a DMD technique which reduces perceivable visual artifacts, in particular, rainbow artifacts. <P>SOLUTION: The projection system includes a color wheel and at least one digital micromirror device. The color wheel generates light of different colors from a light source. The respective colors are sequentially generated with respect to a predetermined color phase. The each digital micromirror device has a plurality of micromirrors. At least one of the plurality of micromirrors is activated in respective different parts of two consecutive color phases in response to a control signal. The projection system further includes a lens configured to project light reflected from at least one of the digital micromirror devices onto a projection surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
