Abstract
It is made possible to view a high-resolution clear stereoscopic image from any direction without taking the projection timing of two-dimensional images into consideration. First and second polygonal mirrors each including mirrors arranged in a ring form around a rotation axis of a screen are disposed. An electronic projector is disposed on an extended line of the rotation axis of the screen so as to be opposed to mirror surfaces of the polygonal mirrors. The electronic projector emits concentrically arranged first and second frame image groups each including frame images arranged in a ring form. The first and second frame image groups are reflected respectively by the first and second polygonal mirrors and projected onto the rotating screen. As the screen rotates, each of the first and second image groups is projected onto the screen and displayed in order from frame image to frame image.
