Abstract:
A method of reproducing three-dimensional images by a three-dimensional image-reproducing device provided with image projecting means and a directional reflective screen for collecting light from said image projecting means toward a specific position in a horizontal direction and diffusing the light from said image projecting means in a vertical direction,said method characterized in that an observer observing three-dimensional images, said directional reflective screen and said image projecting means are positioned with respect to each other such that the observer is outside a region traversed by a portion of light rays which enter said directional reflective screen from said image projecting means, then are reflected by a surface of said directional reflective screen not contributing to reproduction of the three-dimensional images, and then form a mirror image or a conjugate image of said image projecting means.
