IMAGE DISPLAY SYSTEM, IMAGE DISPLAY APPARATUS, AND IMAGE DISPLAY METHOD
First Claim
1. An image display system for superimposing a virtual space image onto a real world image and displaying the resultant composite image on an image display apparatus that is of a hand-held type,the image display apparatus including:
- a housing;
a stereoscopic display section which is provided on a front surface of the housing and is capable of providing an image that is stereoscopically visible by naked eyes; and
a first imaging section and a second imaging section provided on a back surface of the housing, andthe image display system comprising;
a marker detection section which automatically detects a marker placed in a real world from a real world image shot by at least one of the first imaging section and the second imaging section;
a virtual camera control section which determines and updates positions and orientations of a pair of virtual cameras including a first virtual camera and a second virtual camera in a virtual space, based on the marker in the real world image detected by the marker detection section;
a first virtual space image generation section which generates a first virtual space image by drawing the virtual space, based on the first virtual camera;
a second virtual space image generation section which generates a second virtual space image by drawing the virtual space, based on the second virtual camera; and
a display control section which displays an image that is stereoscopically visible by naked eyes on the stereoscopic display section, based on a first composite image obtained by superimposing the first virtual apace image onto a first real world image shot by the first imaging section, and on a second composite image obtained by superimposing the second virtual space image onto a second real world image shot by the second imaging section.

Abstract
A hand-held image display apparatus includes a touch panel, a stereoscopic display apparatus, a first imaging section, and a second imaging section. The hand-held image display apparatus detects a marker from a real world image shot by at least one of the first imaging section and the second imaging section, and determines the relative positions of a virtual object and a pair of virtual cameras with respect to each other in a virtual space, based on the result of the detection. Then, the hand-held image display apparatus superimposes virtual space images drawn based on the first virtual camera and the second virtual camera, onto the real world images shot by the first imaging section and the second imaging section, and displays images that are stereoscopically visible by naked eyes, on the stereoscopic display apparatus.
