Abstract
The invention is characterised in that it has a reference/predictive grouping unit 105 into which a plurality of images which are to be encoded is input together with the relevant camera position data, and whereby the plurality of images which are to be encoded is grouped into reference images and predictive images which are predictively encoded from the reference images, a reference image encoding unit 106 which encodes the reference images, a predictive image encoding unit 108 which uses reconstructed reference images to encode predictive images, and a reference relationship table compilation unit 109 which compiles a reference relationship table detailing reference relationships, encoded data positions and camera positions, and outputs the reference relationship table and the encoded data.
