Method and apparatus for encoding motion vector, and method and apparatus for encoding/decoding image using same
A method and an apparatus for encoding a motion vector, and a method and an apparatus for encoding/decoding an image using the same are disclosed. The apparatus includes: a prediction candidate selector for selecting one or more motion vector prediction candidates; a predicted motion vector determiner for determining a PMV among the one or more motion vector prediction candidates; and a differential motion vector encoder for calculating a differential motion vector encoder for calculating a DMV by subtracting the predicted motion vector having been determined, from the current motion vector, and encoding the d having been calculated. The apparatus encodes a motion vector by using the prediction motion vector which is more accurately predicted, and reduces an amount of bits required for encoding information of the predicted motion vector, thereby improving the compression efficiency.
