    Abstract: An encoding device (100) that realizes further improvements is provided with a processing circuit and a memory. Using this memory, the processing circuit converts each of blocks, respectively comprising a plurality of pixels, into a block comprising a plurality of conversion coefficients using the base, reconstructs a block comprising the plurality of pixels by performing at least inverse conversion on each block comprising the plurality of conversion coefficients, determines filter characteristics for the boundary of two reconstructed blocks adjacent to each other on the basis of a combination of the bases used for the conversion of each of the two blocks (steps S1201, S1202), and performs a deblocking filter process having the determined filter characteristics (step S1203).

    Abstract: An encoder partitions into blocks using a set of block partition modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block partition mode indicating that the number of partitions is three.
