Summary:To suppress block distortion.SOLUTION: In accordance with a block structure having a hierarchical structure in which a transform block, a prediction block, and a coding block are unified, a bitstream is decoded and a decoded image is generated. A deblocking filter is applied to pixels of a line orthogonal to a sub-block boundary that is a boundary between sub-blocks obtained by dividing the transform block of the decoded image. The present technology can be applied to, for example, a case where encoding and decoding of an image are performed.SELECTED DRAWING: Figure 8 【課題】ブロック歪みを抑制する。【解決手段】変換ブロックと予測ブロックと符号化ブロックとが統一された階層構造を有するブロック構造に従って、ビットストリームが復号されて復号画像が生成される。復号画像の変換ブロックを分割したサブブロックの境界であるサブブロック境界と直交するラインの画素に、デブロックフィルタが適用される。本技術は、例えば、画像の符号化及び復号を行う場合に適用することができる。【選択図】図８
