<P>PROBLEM TO BE SOLVED: To secure a constant and continuous light quantity while driving semiconductor lasers with high light emitting efficiency. <P>SOLUTION: A light source device includes: a light source section 17 which has a plurality of semiconductor lasers (21a to 21f); a projection light processing section 36 which respectively pulse-drives the plurality of semiconductor lasers 21a to 21f of the light source section 17 in the same period and at the same duty, and by complementing the intermittent term with one another to adjust phases so as to be always the same number of lighting; input systems 11 and 12 which input an image signal; and projection systems 13 to 16, 18 and 19 which uses light generated in the light source section 17 and forms and projects an optical image corresponding to the image signal to be inputted. <P>COPYRIGHT: (C)2011,JPO&INPIT |
