Abstract

An image photographed by a CCD camera is captured, and this captured image is mapped onto a marker object. The perspective of the captured image is modified in accordance with whether the marker object is far away or near. When the marker object is far away, the perspective is modified to give the impression that it is nearer to the viewer than its actual position. The perspective is modified by varying the scaling factor S of the marker object. When the marker object is behind an obscuring object, an image is generated to make it appear as if the marker object is in front of the marker object. The marker object can be made to appear as if in front of the obscuring object, by increasing the priority that is assigned to the marker object for hidden-surface removal.
