Patent Images
1. An image presentation apparatus comprising:
- a storage device storing a three-dimensional image;
a display having a position and orientation which are variable;
a projecting device projecting the three-dimensional image stored in the storage device on a two-dimensional image plane, to thereby obtain a two-dimensional image, a viewpoint being independent of a position and orientation of the image plane; and
a decision device deciding a position of the viewpoint and the position and orientation of the image plane at the time of the projection by the projecting device according to the position and orientation of the display, the two-dimensional image being displayed on the display,wherein after the position of the viewpoint is initially decided, the position and orientation of the image plane are decided in accordance with the position and orientation of the display, and then the position of the viewpoint is decided so as to keep the position of the viewpoint constant.

Abstract
Using a mobile display having ordinary degree of resolution which is directly held by a user'"'"'s hand or supported by a supporter, a three-dimensional virtual world is projected on a two-dimensional plane while varying the positional relations between the viewpoint and the image plane according to the position and orientation of the mobile display, and the resulting two-dimensional image is displayed on the mobile display and presented to the user.
