ENCODER, DECODER, ENCODING METHOD, AND DECODING METHOD

Abstract: an encoder includes circuitry and memory. using the memory, the circuitry, in inter prediction processing: derives a first motion vector of a current block to be processed, using a motion vector of a previous block which has been previously processed; derives a second motion vector of the current block by performing motion estimation in the vicinity of the first motion vector; and generates a prediction image of the current block by performing motion compensation using the second motion vector.
