Abstract
An image display system for providing images such that a right eye and a left eye of an observer see different images, respectively. The image display system includes: a camera for taking a picture of said observer and then outputting an image of the observer; a pair of liquid crystal display devices transparent to light; an image generation device for generating a back-light image based on an image output signal provided by the camera; a pair of CRT devices for displaying a back-light image generated by the image generation device to illuminate the pair of liquid crystal display devices from their back sides; a mirror for combining images present on the pair of liquid crystal display devices into one image; and optical elements for giving directivity to back-light emitted by the pair of back-lighting devices so that one of the pair of CRT devices provides back-light illumination for the right eye and the other one of the pair of CRT devices provides back-light illumination for the left eye.
