An image decoding method of dividing an input image signal into pixel blocks, and performing inter prediction on divided pixel blocks, comprising:
selecting predicted motion information (2755) from a plurality of motion information in decoded regions, based on information acquired in accordance with first information regarding a method of selecting the predicted motion information; and
predicting motion information (2559) of a decoding target block by using the predicted motion information,
wherein the first information includes second information for specifying a position in the decoding target block, the position in the decoding target block being used to select the motion information, and
the position in the decoding target block being used to select the motion information is set based on whether a representative motion information position used to derive the motion information is outside of a picture.
