<P>PROBLEM TO BE SOLVED: To provide the optical system of a stereoscopic video display device capable of realizing the observation of a stereoscopic video in which binocular parallax, the convergence of both eyes and the focusing action of the eye which are main elements to give a stereoscopic effect are not contradictory. <P>SOLUTION: In the eccentric optical system 2 including an active type catoptric element 3 capable of changing its reflecting direction at every position on a reflection surface, and at least one reflection surface 14 having rotationally asymmetric surface shape, the optical system 2 is arranged between a pupil surface 1 and an image surface 4 and satisfies a following expression. The stereoscopic video display device is constituted by arranging such an eccentric optical system and a video display element corresponding to observer's right and left eyes one by one respectively. (1) (distance between the pupil and the eccentric optical system)/(focal distance)≥0.6. <P>COPYRIGHT: (C)2003,JPO |
