Abstract:
1. An information processing apparatus for processing content and displaying an image comprised of elemental images, the elemental images including hierarchical images having a data structure where pieces of image data with different resolutions generated from the single elemental image are hierarchized according to resolution, the information processing apparatus comprising: a viewpoint coordinate acquiring unit configured to receive a request for a shift of a viewpoint for the displayed image and configured to acquire viewpoint coordinates of an image to be displayed next based at least in part on a hierarchical coordinate system comprising levels of hierarchical image data representing different resolutions, wherein image data at a particular hierarchical level is decoded according to the position of the viewpoint; an elemental image rendering unit configured to render the elemental image; and a coordinate conversion unit configured to convert a hierarchical coordinate system unique to each elemental image into a display coordinate system, based on image correspondence data where a layout of the elemental image is expressed by a relative position in relation to another elemental image, and configured to calculate positional coordinates in the display coordinate system of each elemental image corresponding to the viewpoint coordinates of the image to be displayed next; and an elemental image integrating unit configured to generate a displayed image where the elemental image rendered by the elemental image rendering unit is arranged in the respective positional coordinates.
