ABSTRACT:
A three-dimensional image display device comprises a screen shutter unit, a shutter control unit, a display unit, and a display control unit. The screen shutter unit comprises a plurality of long and narrow shutters capable of passing and intercepting light rays. Each of the shutters is positioned vertically and arranged horizontally to each other at equal intervals. The shutter control unit selects shutters from the plurality of shutters at predetermined intervals as long slits to pass light rays through, and moves entire slits horizontally at predetermined time intervals. The display unit displays each image corresponding to each slit on an image display screen provided at a predetermined distance from an arrangement of the shutters. The display control unit displays as images corresponding to respective slits the images obtained by projecting a three-dimensional image to be displayed on the image display screen through the slits synchronously with a moving timing of the slits controlled by the shutter control unit. The images are displayed on respective positions on the image display screen corresponding to respective slits. A part of the image displayed on the image display screen corresponding to the slits is selected through the slits and reaches the viewer's eyes, thereby allowing the viewer to recognize the three-dimensional image.
