PURPOSE:To eliminate the need for the use of special glasses by forming a screen whose height in the axial direction varies with a prescribed inclination and providing a rotating and driving means rotating a columnar body and an image projecting means which projects a video on one edge of the columnar body in synchronization with the rotation of the body. CONSTITUTION:When the image projecting means 5 projects an image on one edge of the columnar body, the image arrives at the screen 7 because a space between both edges of the columnar body forms a light guide path. Since the screen is formed such that its height in the axial direction varies with a prescribed angle along the rotary shaft 2 and the lateral side of the columnar body, a locus on the screen 7 forms a three-dimensional space when the rotating and driving means 3 rotates the columnar body. Consequently, the image projecting means 5 projects an image in synchronization with the rotation of the columnar body. When the image begins to be projected on the screen 7, a viewer catches a stereoscopic video in a three-dimensional space by his eyes'after image effects. Thus, the stereoscopic image generator not requiring special glasses can be obtained. |
