Abstract: A coding device (100) is provided with a circuit (160) and a memory (162) connected to the circuit (160). The circuit (160): selects, from a plurality of tables which are used, during an operation, to correct a reference motion vector into a predetermined direction using a correction value designated by an index, and which have correction values with respectively different intervals between indexes, a first table used for a partition to be coded of an image in a moving image; writes a parameter indicating a first index to be selected from among indexes included in the first table; and codes the partition using the reference motion vector corrected by means of a correction value designated by the first index.

Abstract: An encoder (100) 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.

Abstract: An image encoder is provided, which includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, performs a boundary smoothing operation along a boundary between a first partition having a non-rectangular shape (e.g., a triangular shape) and a second partition that are split from an image block. The boundary smoothing operation includes: first-predicting first values of a set of pixels of the first partition along the boundary, using information of the first partition; second-predicting second values of the set of pixels of the first partition along the boundary, using information of the second partition; weighting the first values and the second values; and encoding the first partition using the weighted first values and the weighted second values.

Abstract: An encoding device (100) is provided with a circuit and a memory connected to the circuit. In an operation, the circuit writes, into a bit stream, a first parameter indicating whether a prediction mode is (i) a multiplex prediction mode for generating a prediction image by superimposition between an inter-prediction image and an intra-prediction image of a to-be-processed block, or (ii) any one of a plurality of prediction modes including a triangle mode for generating a prediction image by dividing the to-be-processed block into triangular regions, and the circuit encodes the to-be-processed block in accordance with the prediction mode.

Abstract: An encoder (100) that encodes a current block in a picture includes circuitry and memory. Using the memory, the circuitry: splits the current block into a first sub block, a second sub block, and a third sub block in a first direction, the second sub block being located between the first sub block and the third sub block; prohibits splitting the second sub block into two partitions in the first direction; and encodes the first sub block, the second sub block, and the third sub block.

Abstract: ABSTRACT A decoder and a method is disclosed that decodes a current block in a picture. The decoder comprises circuitry and a memory. Using the memory, the circuitry performs a first inverse transform on inverse quantized coefficients of the current block using a first inverse transforrn basis without performing a second inverse transform, when the first inverse transform basis used for the first inverse transform is a discrete cosine inverse transform basis.

Abstract: This image encoding method encodes at least one unit contained in a picture, and includes: a first flag generating step (S221) for generating a first flag indicating whether or not the times that a virtual decoder reads encoded data from a buffer for storing the encoded data are set in units of the units; a second flat generating step (S222) for, when the times are set in units of the units, generating a second flag indicating whether the intervals between the read times of the plurality of units are fixed or arbitrary; and a bitstream generation step (S223) for generating an encoded bitstream containing the encoded data, the first flag, and the second flag.
