Abstract

As a user inputs instruction to start up content, an initial image is displayed. A viewpoint shift request is made, viewpoint coordinates are calculated according to the viewpoint shift request. Then verified is whether a hierarchical level has been changed in hierarchical image data due to a shift of the viewpoint coordinates or not. If the hierarchical level has been changed, the node of a hierarchical image is extracted from image correspondence data and then a coordinate transform matrix associated with the node is modified. A new elemental image is decoded, each image is subjected to the coordinate transform based on the image correspondence data so as to evaluate the coordinates on display coordinates. Each elemental image is placed on the evaluated coordinates, which in turn integrates the elemental images and updates a displayed imaged.
