CODING APPARATUS, CODING METHOD, DECODING APPARATUS, AND DECODING METHOD

摘要

The present technique relates to a coding apparatus, a coding method, a decoding apparatus, and a decoding method in which information to control filter processing of an image including a hierarchical structure can be shared.;An enhancement coding unit performs adaptive offset filter processing with respect to a decoded image in an enhancement layer based on control information which is information to control the adaptive offset filter processing and which is used in coding of a base image. The enhancement coding unit codes an enhancement image and generates coded data by using, as a reference image, the decoded image in the enhancement layer on which image the adaptive offset filter processing is performed. A transmission unit transmits the coded data. The present technique can be applied, for example, to a coding apparatus.

1. A coding apparatus comprising:
a filter processing unit configured to perform filter processing with respect to a decoded image in a second hierarchy based on control information which is information to control the filter processing and which is used in coding of an image in a first hierarchy of an image including a hierarchical structure; a coding unit configured to code an image in the second hierarchy and to generate coded data by using, as a reference image, the decoded image in the second hierarchy on which image the filter processing is performed by the filter processing unit; and a transmission unit configured to transmit the coded data generated by the coding unit.
