Zusammenfassung:	To provide an image coding device capable of realizing a further improvement.SOLUTION: An image coding device comprises: a circuit; and a memory connected to the circuit. The circuit divides a picture into a plurality of coding tree units in an operation, divides a first block into a plurality of second blocks by using a first division mode without writing first division information indicating the first division mode when a first block in which at least one side of the plurality of coding tree units is adjacent to an edge of the picture is in a first shape, writes second division information indicating the second division mode, divides at least one of the plurality of second blocks into a plurality of coding units by using the second division mode, and codes the plurality of coding units.SELECTED DRAWING: Figure 11 【課題】さらなる改善を実現できる画像符号化装置を提供する。【解決手段】画像符号化装置は、回路と、回路に接続されたメモリと、を備え、回路は、動作において、ピクチャを複数の符号化ツリーユニットに分割し、複数の符号化ツリーユニットのうち少なくとも一辺がピクチャのエッジに隣接する第１ブロックが第１の形状であるとき、第１分割モードを示す第１分割情報を書き込まずに、第１分割モードを用いて、第１ブロックを、複数の第２ブロックに分割し、第２分割モードを示す第２分割情報を書き込み、第２分割モードを用いて複数の第２ブロックのうちの少なくとも１つを複数の符号化ユニットに分割して、複数の符号化ユニットを符号化する。【選択図】図１１
