<p>When encoding or decoding a perspective image and a depth image, the invention enables multiple formats having different dependence relationships between the perspective image and the depth image during encoding and decoding to be used in a unified manner. For every specified number of items of encoding format switching data, an image encoding device determines one of multiple encoding formats that have different reference relationships between the perspective image and the depth image, and encodes the perspective image and the depth image by means of the determined encoding format. The image encoding device inserts image-to-image reference information in an encoded data string, said image-to-image reference information indicating the reference relationship between the perspective image and the depth image at the time of encoding. Following the reference relationship indicated by the image-to-image reference information, an image decoding device determines a decoding method and a decoding sequence, and decodes the perspective image and the depth image by means of the determined decoding method and the determined decoding sequence.</p> |
