Abstract

The present invention relates to an apparatus capable of displaying a stereoscopic image by projecting an optical signal corresponding to an image source onto a stereoscopic display medium.

Conventional image display devices display an image in two dimensions by emitting a phosphor by an electron gun, or an LCD using liquid crystal, an Actuated Mirror Array (AMA) or a Digital Mirror Array (DAM) using a micro-reflective mirror, and an FFD (Field). Emmit display).

However, since all of these conventional video display devices display images in a plane, the viewing direction is limited to the front side, and the viewable angle is also limited to a partial angle of the front side, and the viewable area of the image is also desired from either direction. There is a constraint that only the face is displayed.

On the other hand, a stereoscopic image display device using a visual difference between left and right eyes in order to realize a stereoscopic image has been proposed, but this apparatus is inconvenient because a special apparatus must be worn for viewing a stereoscopic image.

In order to solve the above-mentioned problems, the present invention provides a means for outputting light corresponding to an image source, a medium for reproducing a stereoscopic image with a difference in the passing distance of the output light, and the light output means. It is equipped with means for appropriately adjusting the output of the image corresponding to the image source, so that the image can be reproduced and displayed in three dimensions on the medium, and the image of the object viewed from that direction in any direction before and after, left, right, up and down without a separate wearing mechanism Provided is a stereoscopic image display device for viewing stereoscopically.
