Abstract

An image decoding apparatus is provided with a CT information decoding unit that decodes division information indicating a division method for binary tree division with respect to a coding node of a coding tree unit, and performs the binary tree division with respect to the coding node by referring to the division information of another decoded coding node.

Claims (6)

1. An image decoding apparatus configured to decode a picture for each coding tree unit, comprising:

a header decoding circuitry configured to receive coded data including the coding tree unit; and

a division information decoding circuitry configured to decode division information indicating a division method of division with respect to coding nodes in the coding tree unit, wherein

the division information decoding circuitry is configured to determine whether or not a hierarchy of the coding node is deeper than a predetermined hierarchy and refer to the division information of another decoded coding node,

whether or not the hierarchy of the coding node is deeper than the predetermined hierarchy is determined by using a depth, and

in a case that a value of the depth is greater than zero, the hierarchy of the coding node is determined as deeper than the predetermined hierarchy.
