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 9):
A non-transitory computer-readable storage medium having embodied thereon computer-readable codes, which when executed by a processor of an encoder causes the encoder to execute a method of encoding an image, the method comprising:\n determining a plurality of maximum coding units by splitting an image; generating split information used to hierarchically split a maximum coding unit, among the plurality of maximum coding units, into coding units of depth including at least one of a current depth and a lower depth; when a reference image of a candidate block and a reference image of a current prediction unit are different, determining whether each of the reference image of the candidate block and the reference image of the current prediction unit is a long-term reference image, wherein the candidate block is from among a plurality of candidate blocks adjacent to the current prediction unit; obtaining long-term reference information indicating whether the reference image of the current prediction unit is a long-term reference image; when both of the reference image of the candidate block and the reference image of the current prediction unit are the long-term reference images, obtaining a motion vector prediction candidate without scaling a motion vector of the candidate block; determining difference information by using the motion vector prediction candidate and a motion vector of the current prediction unit; and generating a bitstream comprising the split information, the long-term reference information and the difference information, wherein, when one or more prediction units that comprise the current prediction unit are obtained from a coding unit of the current depth, the split information indicates a non-split of the current depth.
