Abstract
An encoding method executed by an encoding device includes: in encoding a motion vector, determining, from among a plurality of predetermined prediction modes, a prediction mode to be used for determining a prediction vector which is a prediction value of the motion vector (S3901); and transmitting information indicating the determined prediction mode to a decoding device (S3902). The plurality of predetermined prediction modes include at least: a first mode that uses, as the prediction value, an average value of a plurality of reference motion vectors to be referenced in encoding the motion vector, the average value being converted to an integer by truncating a fractional part of the average value; and a second mode that uses, as the prediction value, an average value of the plurality of reference motion vectors, the average value being converted to an integer by rounding the fractional part of the average value.
