Abstract
An image encoding/decoding method is disclosed. An image decoding method of the present invention may comprises determining step for determining whether or not to derive second motion information when a current block includes first motion information only and for which bi-directional prediction is available, a deriving step for deriving the second motion information based on the first motion information, and a predicting step for generating a prediction block of the current block by performing BIO prediction based on the first motion information and the second motion information.
