摘要：
An encoder which includes circuitry and memory is provided. The circuitry: calculates a cost for each of search points included in a first set; determines whether a base search point has a lowest cost in the first set; when the cost of the base search points is lowest, selects the base search point as a first best search point; when the cost of the base search points is not lowest, calculates a cost for each of search points included in a second set, selects a search point having a lowest cost from among the first set and the second set, as a second best search point, and encodes a current block to be encoded, using a motion vector corresponding to the first best search point or the second best search point.
