Abstract
A hard disk drive stores hierarchical image data, a speed map holding, for each tile image, an index of the processing time required to render a tile image having a predetermined image size obtained by partitioning the image, and scenario data which defines viewpoint shifting. In a control unit of an information processing apparatus having a function of displaying an image, an input information acquisition unit acquires information with respect to the user's input operation via an input device. A loading unit loads necessary data for image displaying from the hard disk drive. A shifting condition adjustment unit adjusts the viewpoint shifting speed based upon the speed map. A frame coordinate determination unit sequentially determines frame coordinates of a display area. A decoding unit decodes compressed image data. A display image processing unit renders a display image.
