Abstract:
An encoding device and method, and a decoding device and method, capable of encoding and decoding a multi-viewpoint image in accordance with a mode having compatibility with an existing mode. A compatible encoder generates a compatible stream by encoding an image that is a compatible image. An image converting unit converts the resolution of images that are auxiliary images. An auxiliary encoder generates an encoded stream of the auxiliary image by encoding the auxiliary image of which the resolution is converted. A compatibility information generating unit generates, as compatibility information, information that designates the image as a compatible image. A multiplexing unit transmits the compatible stream, the encoded stream of the auxiliary image, and the compatibility information. The encoding device can encode a 3D image of the multi-viewpoint mode.
