Abstract

The present invention relates to an apparatus and a method for determining a motion vector. The apparatus for determining the motion vector according to an embodiment of the present invention comprises: a block identification unit for identifying a same position block included in a reference picture as a block which is at the same position as a present block; a motion block determination unit for determining whether the present block is a motion block on the basis of the motion vector of the same position block; a motion vector decision unit for deciding the motion vector of the present block according to the determined result; and a resolution conversion unit for converting the resolution of the motion vector of the same position block. According to the present invention, the motion vector resolution is decided in each image region or each motion vector. Inter-prediction encoding or decoding is performed by using the motion vector having the motion vector resolution which is adaptively decided with respect to images. In addition, the present invention enables efficient encoding by adaptively changing the motion vector resolution in predetermined region units of the images and performing the inter-prediction encoding for the images.
