Method and apparatus for encoding/decoding motion vector considering accuracy of differential motion vector and apparatus and method for processing images therefor

The present invention relates to a method and an apparatus for encoding/decoding images using adaptive motion vector resolution. The method for encoding the images of the present invention comprises the steps of: determining motion vector resolution in each region or each motion vector; and performing inter-prediction encoding by using the motion vector according to the motion vector resolution determined in each region or each motion vector. The present invention can efficiently encode the images by adaptively changing the motion vector resolution in predetermined region units of the images and performing the inter-prediction encoding for the images.
