The present technology pertains to an encoding device, encoding method, decoding device, and decoding method that enable the sharing or prediction of information pertaining to a reference image of an image having a multi-layered structure. An enhancement encoding unit sets reference-image-specification generation information used in generating reference-image-specifying information of an enhancement image using reference-image-specifying information as information pertaining to the reference image of a base image and reference-image-specifying information as information pertaining to the reference image used when encoding the enhancement image. The enhancement encoding unit encodes the enhancement image using the reference image, generating encoded data. A transmission unit transmits the encoded data and the reference-image-specification generation information. The present technology can, for example, be applied to an encoding device. |
