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

摘要

Provided is an image encoding method capable of responding appropriately to a 3D video format constituted by a basic layer and an enhanced layer. The image encoding method comprises a video layer and a system layer wherein the video layer comprises an encoding step (S1801) for generating an encoding stream by encoding an image, the system layer comprises a multiplexing step (S1802) for generating a system stream by multiplexing (i) an identifier which indicates whether or not an image format is a right/left mixture format which includes the basic layer and the enhanced layer and includes a left viewpoint image area and a right viewpoint image area in one picture, and (ii) encoding stream, and wherein in the encoding step (S1801), if the image format is a right/left mixture format, an image which includes the basic layer and the enhanced layer and includes a left viewpoint image area and a right viewpoint image area in one picture, is encoded to generate an encoding stream.
