ENCODING DEVICE, ENCODING METHOD, DECODING DEVICE, AND DECODING METHOD

摘要

The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of suppressing the amount of information without degrading the image quality of an image of a viewpoint that is used when the compatibility is secured in a case where a multi-viewpoint image is encoded. A compatible encoder generates a compatible stream by encoding an image A1 that is a compatible image. An image converting unit lowers the resolution of images B1 and C1 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 lowered. A multiplexing unit transmits the compatible stream and the encoded stream of the auxiliary image. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.
