<P>PROBLEM TO BE SOLVED: To reduce a color break-up and to provide high quality projection images, as to a technology for a projector which uses a solid-state light emitting element and a tilt mirror device and a driving method for a spatial light modulator. <P>SOLUTION: The method of driving the spatial light modulator includes: a 1st colored light sub-frame pulse signal generating step for generating a sub-frame pulse signal for first colored light R1 through R8, B1 through B8; a 2nd colored light sub-frame pulse signal generating step for generating a sub-frame pulse signal for a second colored light G1 through G8; a sub-frame pulse signal arranging step for arranging the sub-frame pulse signals for the respective colored light so that at least three of the sub-frame pulse signals for the first colored light R1 through R8, B1 through B8 adjoin either one of the sub-frame pulse signals for the second colored light G1 through G8 during at least one frame of the image; and a movable mirror device driving step for driving a plurality of movable mirror devices in accordance with the sub-frame pulse signals for the respective colored light arranged in the step of arranging the sub-frame pulse signals, the movable mirror devices being alternatively moved at least to a first reflecting position and a second reflecting position. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
