Abstract:
The motion vector determining method involves determining a candidate motion vector list comprising motion vectors of a plurality of candidate blocks referred so as to predict a motion vector of a current block, when a reference image of a first candidate block from among the plurality of candidate blocks is different from a reference image of the current block, determining whether or not to use a motion vector of the first candidate block from the candidate motion vector list, based on whether each of the reference image of the current block and the reference image of the first candidate block is a short-term reference image or a long-term reference image, and determining the motion vector of the current block by using a candidate motion vector selected from among the motion vectors comprised in the candidate motion vector list.

Claim (Index 6):
An apparatus for encoding an image, the apparatus comprising:\n at least one processor configured to: when a reference picture of a candidate block and a reference picture of a current block are different, determine whether each of the reference picture of the candidate block and the reference picture of the current block is a long-term reference picture, wherein the candidate block is from among a plurality of candidate blocks adjacent to the current block; obtain long-term reference information indicating whether the reference picture of the current block is a long-term reference picture; when one of the reference picture of the candidate block and the reference picture of the current block is a long-term reference picture and the other one of the reference picture of the candidate block and the reference picture of the current block is a short-term reference picture, determine that a motion vector of the candidate block is un-available; when both of the reference picture of the current block and the reference picture of the candidate block are short-term reference pictures, obtain a motion vector prediction candidate by scaling the motion vector of the candidate block; and determine difference information by using the motion vector prediction candidate and a motion vector of the current block.
