Abstract: An encoder includes circuitry and memory. The circuitry, using the memory: writes, into a bitstream, one or more parameters including a first parameter indicating that a first partition of an image is to be split into a plurality of partitions including at least a second partition which is a non-rectangular partition; splits the first partition, based on the first parameter; and encodes at least the second partition.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry performs: deriving a plurality of reference samples positioned on a first line, for intra prediction; and generating a prediction image using the plurality of reference samples. The deriving includes interpolating a value on a second line perpendicular to the first line using values of encoded pixels on the second line to generate an interpolated value, and deriving one of the plurality of reference samples by projecting the interpolated value onto the first line.

Abstract: An encoder is an encoder which encodes image information and includes memory and circuitry accessible to the memory. The circuitry derives, from the image information, a binary data string according to binarization for arithmetic encoding, and outputs a bit stream including the binary data string and application information indicating whether or not the binary data string has been arithmetic encoded. The circuitry outputs, as the bit stream, a string including as the binary data string, a data string which has not been arithmetic encoded; and, as the application information, information indicating that the binary data string has not been arithmetic encoded.

Abstract: When a block (MB22) of which motion vector is referred to in the direct mode contains a plurality of motion vectors, 2 motion vectors MV23 and MV24, which are used for inter picture prediction of a current picture (P23) to be coded, are determined by scaling a value obtained from averaging the plurality of motion vectors or selecting one of the plurality of the motion vectors.

Abstract: A motion vector derivation unit includes a comparison unit for comparing a parameter TR1 for a reference vector with a predetermined value to determine whether it exceeds the predetermined value or not; a switching unit for switching selection between the maximum value of a pre-stored parameter TR and the parameter TR1 according to the comparison result by the comparison unit; a multiplier parameter table (for multipliers); and a multiplier parameter table (for divisors) for associating the parameter TR1 with a value approximate to the inverse value (1/TR1) of this parameter TR1.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry performs prediction on an image. A motion vector predictor list used in the prediction includes a spatially neighboring motion vector predictor obtained from a block spatially neighboring a current block, and a spatially broad motion vector predictor obtained from a block positioned at any of a plurality of predetermined positions in a second range that is broader than a first range that spatially neighbors the current block. The plurality of predetermined positions are defined by a regular interval using the top-left of a current picture as a reference point.
