The present invention relates to a method for determining a reference image for inter prediction, and to an inter prediction method according to same. The method for determining a reference image includes: confirming the slice type of a block; if the slice type is a B slice type capable of performing unidirectional prediction or bi-directional prediction, determining the inter prediction direction of the block as a first direction, a second direction, or both directions; if the inter prediction direction is not the second direction, determining a reference index for a block as a first direction reference index from a first direction reference picture list; and, if the inter prediction direction is not the first direction, determining the reference index for the block as a second direction index from a second direction reference picture list. |
