Abstract: A three-dimensional image display system utilizing both a light beam reproducing method and a shadowgraph type multi-view parallax method, in which three-dimensional stereoscopic images are observed continuously from the rear to front of the display unit is provided. A color filter (22) is disposed on an observer (23) side of a white-color point light source array (21), and, in an area apart from the color filter (22) and white point light source, light beams emitted from the white-color point light source are selectively colored by the color filter (22) for generating a group of a number of light beams corresponding to a scattered light from each point of an object, while in the region in the vicinity of the point light source and the color filter (22) in which a sufficient number of light beams cannot be reproduced, the light beams are selectively colored by the color filter (22) so that image data reaching the eye from the white-color point light source through the color filter (22) performs a view-dependent parallax type stereoscopic display operation not only laterally but also vertically, and further, in the intermediate region, these two operations are mixed, so that a stereoscopic image is continuously joined to each other.
