Image Coding Device And Method

Abstract: The present disclosure pertains to an image coding device and method which enable a decrease in coding efficiency to be suppressed. In the present invention the following are provided: a coding unit for coding image data consisting of multiple layers; an interlayer prediction correlation information generation unit for generating information related to interlayer prediction of a current slice if the current slice layer is an enhancement layer and if the slice type of such current slice is a P slice or B slice; and a transmission unit for transmitting the coded data of the image data such coded data generated by the coding unit and information related to interlayer prediction such information generated by the interlayer prediction correlation information generation unit. The present disclosure can be applied to for example an image coding device that codes image data in a scalable manner or an image processing device such as an image decoding device that decodes coded data which is image data that was coded in a scalable manner.
