Abstract
The present disclosure provides a motion vector encoding/decoding method and apparatus using a motion vector resolution combination, and an image encoding/decoding method and apparatus using the same. A motion vector encoding apparatus include: an encoding cost calculator for calculating an encoding cost according to a motion vector resolution for each motion vector resolution combination including one or more motion vector resolutions; a resolution combination determiner for selecting a motion vector resolution combination by using the encoding cost calculated for each motion vector resolution combination; and a motion information encoder for outputting encoded motion vector data generated by encoding a motion vector determined according to the motion vector resolution combination selected, as a bitstream. Accordingly, an efficient motion vector resolution combination is selected adaptively and a motion vector is determined and decoded based on the motion vector resolution combination, thus making it possible to improve compression efficiency.
