Patent ID: 8360581

Claim:
A stereoscopic image display system that directs images with binocular parallax separately at left and right eyes of an experiencing person to allow the experiencing person to visually recognize a stereoscopic image, the system comprising: a retroreflection optical part having a plane of incidence oriented in a substantially horizontal direction that is perpendicular to the experience person's upper body, and reflecting a light beam, which is incident on the plane of incidence, in a direction of incidence of the incident light beam; a half mirror disposed so as to traverse a field of view of an experiencing person who sees the retroreflection optical part in a visually recognizable region set previously around a periphery of the retroreflection optical part; an image light beam emission part emitting an image light beam toward the half mirror from an opposite side to a side where the experiencing person is present; and an image transmission part transmitting an image to the image light beam emission part, wherein the half mirror reflects, toward the retroreflection optical part, the image light beam emitted from the image light beam emission part, the image light beam emission part and the half mirror are in a positional relation set such that the image light beam reflected from the half mirror becomes optically conjugate with the field of view of the experiencing person, a plurality of projection units each including the half mirror and the image light beam emission part are arranged around the periphery of the retroreflection optical part at intervals set such that a distance between the visually recognizable regions corresponding to the adjacent projection units becomes equal to a distance between eyes of the experiencing person, and the image transmission part transmits parallax images of an object as a display target seen from directions corresponding to the arrangement positions of the respective projection units to the image light beam emission parts of the respective projection units in accordance with the arrangement positions of the respective projection units.
