ABSTRACT:
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.
