1. A decoding method, comprising:
configuring a first list comprising a plurality of first candidates using first motion information of a plurality of spatial neighboring blocks and second motion information of a temporal neighboring block of a prediction target block;
updating the first list by adding an additional candidate derived based on a second list to the first list in a case that the number of the plurality of the first candidates in the first list is less than a maximum number of candidates of the first list;
determining third motion information of the prediction target block by selecting one of the plurality of first candidates and the additional candidate in the first list as the third motion information of the prediction target block; and
performing inter prediction on the prediction target block using the third motion information of the prediction target block,
wherein the second list comprising a plurality of fourth motion information is configured using a plurality of fifth motion information derived before decoding of the prediction target block, and
wherein one of the plurality of fourth motion information of the second list is selected as the additional candidate to be added to the first list.
