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 encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry corrects a base motion vector using a correction value 5 in a fixed direction; and encodes a current partition by using the corrected base motion vector corrected. The correction value is specified by an index indicating one of correction values included in a table. The table is selected from among a plurality of tables, wherein the correction values in one of the plurality of tables have different increments from the correction values in 10 another one of the plurality of tables. 205300261(

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 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.
