Abstract (in Japanese) (See Japanese page) 
(in English) We have developed a Lens-shiftable projector of DLPTM using a non-telecentric optical system that requires no prism. In the optical engine, the ilumination system is always anchored in the position and the pupil position of the projection lens changes in conjuction with the projection lens in appearance. The F-number of the projection lens is reduced less than the F-number of the illumination system and optimized in consideration of the performance and cost. In addition, the optical engine has a fixed aperture in front of the projection lens, which has the opening size equal to the F-number of the illumination system. We integrate these technologies to provide the Lens shiftable projector that offers high-bright and high-contrast images with a compact structure.
