ENCODING DEVICE AND ENCODING METHOD, AS WELL AS DECODING DEVICE AND DECODING METHOD.

摘要

The present technology relates to an encoding device and a encoding method as well as a decoding device and a decoding method which are capable of suppressing the amount of information without degrading the image quality of an image of a view used when securing compatibility in a case when performing encoding for a multi-view image. A compatibility-use encoder encodes an image A1 which is a compatible image to generate a compatible stream. An image conversion unit decimates an image B1 and an image C1 which are auxiliary images. An auxiliary encoder encodes the decimated auxiliary images to generate an encoded stream of the auxiliary images. A frame packing unit transmits the compatible stream and the encoded stream of the auxiliary images. The present technology can be applied, for example, to an encoding device for encoding a 3D image in a multi-view method.
