Abstract: PROBLEM TO BE SOLVED: To obtain a compact and inexpensive projector device projecting a high-luminance picture by collecting and synthesizing only the high-luminance center parts of light beams condensed by a light condensing means from plural light sources, illuminating a finite aperture with the synthesized light and forming a picture. SOLUTION: The light beams emitted from electrode discharge type lamps 1a to 1c to the periphery are respectively condensed by condensing mirrors 3a to 3c.
