Abstract
A three-dimensional image reproducer receives a video signal including three-dimensional information including X and Y information constituting a plane and Z information constituting a depth. This apparatus causes particles to fall with respect to one line. The line from which the particles fall is changed in the Z direction based on the Z information. A light source generates a light beam toward the falling particle based on a video signal. The generated light beam is scanned in the X and Y directions. The focal point of the light beam is controlled to move in the Z direction in synchronism with the change of the line from which the particles fall. The image formed by the particles is viewed as a three-dimensional image if viewed from the Z direction.
