Abstract
The orientation of an image display device is maintained fixed relative to the viewer, the image display device is enclosed in a transparent body, and by detecting rotation angles of the image display device with respect to the transparent body, an image that is to be viewed when the transparent body is held in a hand or the like is displayed on the image display device, thereby enabling the viewer to view a displayed object from any desired direction as if he is holding the object in his hand. The three-dimensional image display apparatus has an image display device whose display surface is held fixed relative to the viewer, a transparent body for accommodating the image display device therein, an encoder for detecting rotation angles of the image display device with respect to the transparent body, an orientation detector for calculating the difference between the orientation of the transparent body and the orientation of the image display device on the basis of the output of the encoder, and an image generator for generating an image for display on the image display device in accordance with the output of the orientation detector.
