| 摘要 |
The present invention pertains to an encoding device, an encoding method, a decoding device, and a decoding method which enable encoding and decoding of multi-view images using a method compatible with current methods. A compatibility encoder encodes an image (A1) that is a compatible image and generates a compatible stream. An image converter converts the resolution of an image (B1) that is an auxiliary image and an image (C1). An auxiliary encoder encodes an auxiliary image for which the resolution has been converted and generates an encoded auxiliary image stream. A compatibility data generation unit generates, as compatibility data, data specifying the image (A1) as the compatible image. A multiplexing unit transmits the compatible stream, the encoded auxiliary image stream, and the compatibility data. The present invention can be applied, for example, to an encoding device that encodes multi-view 3D images. |
