An image display system which provides first and second images such that the right eye and the left eye of an observer see the first and second images at different times, respectively. The image display system comprises a camera for taking a picture of the observer and then outputting an image of the observer; a liquid crystal display device transparent to light, for displaying the first and second images at the different times, respectively; a back-lighting device which displays back light images to illuminate the liquid crystal display device from a back side thereof, at the different times; and an optical element for giving directivity to back light emitted by the back-lighting device so that the back-lighting device provides back light illuminations of the LCD device for the right and left eyes at the different times. The apparatus detects centroids or contours of images of the observer taken by the camera, and generates the back-light images on the basis of the centroids or contours. The apparatus synchronizes the display of the back-light images with the display of the first and second images, respectively.

Image display system

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.

A space modulation device 10 displays an image for right eye and an image for left eye. An observer image display device 12 displays an image of a half surface of an observer's face obtained by an imaging device 14 and a negative-positive reversed image of the image of the half surface of the face. A lens 11 allows the image for right eye or the image for left eye to be observed to the right eye or the left eye of the observer using the image of the half surface or the negative-positive reversed image thereof as an illumination for the spatial modulation device 10 from the back thereof.
