During zooming from a wide angle end to a telephoto end, the first and third lens units move to the object side, the second lens unit moves to the image side, and the aperture stop moves to the object side along a convex path. Radii of curvature of object- and image-side lens surfaces of a lens closest to the object side in the second lens unit, focal lengths of the entire zoom lens at the wide angle end and the telephoto end, and focal lengths of the first and second lens units are set properly. | 03-03-2011 |
20110063578 | ILLUMINATION OPTICAL SYSTEM AND IMAGE PROJECTION APPARATUS - The illumination optical system includes an integrator configured to divide light from a light source into plural light fluxes, and a collection optical system configured to collect the plural light fluxes from the integrator toward an illumination surface. A rear principal point of the collection optical system is located closer to the light source than a front principal point of the collection optical system. The configuration provides a compact illumination optical system which brightly illuminates the illumination surface with the light and enables high contrast image projection. | 03-17-2011 |

20120154551 | STEREO IMAGE DISPLAY SYSTEM, STEREO IMAGING APPARATUS AND STEREO DISPLAY APPARATUS - The stereo display apparatus displays parallax images to present a stereo image. The apparatus acquires the parallax images and information on a maximum pixel shift amount and a minimum pixel shift amount of the parallax images, calculates maximum and minimum relative parallax amounts corresponding to the maximum and minimum relative parallax amounts, by using the information on the maximum and minimum pixel shift amounts and a display condition, and determines whether or not at least one of the maximum and minimum relative parallax amounts exceeds a fusional limit criterion value. The apparatus determines whether or not a difference between the maximum and minimum relative parallax amounts exceeds a fusional limit range amount if the at least one of the maximum and minimum relative parallax amounts exceeds the fusional limit criterion value. | 06-21-2012 |
