Abstract

One embodiment of the present invention relates to a method and apparatus for motion vector encoding/decoding using a motion vector resolution limitation, and to an image encoding/decoding method and apparatus using same. The embodiment of the present invention provides a motion vector encoding method, comprising: calculating encoding costs for each limitation level of a motion vector resolution which is limited by levels; selecting a limitation level of the motion vector resolution using the encoding costs calculated for each limitation level; and outputting motion vector encoded data obtained by encoding the motion vector determined by the selected limitation level of the motion vector resolution, and resolution limitation index data obtained by encoding a resolution limitation index for indicating the selected limitation level of the motion vector resolution. According to the embodiment of the present invention, the resolution of the motion vector is adaptively limited to determine and encode a motion vector, thereby improving compression efficiency.
