- The present invention relates to an image decoding/encoding apparatus and a computer-readable recording medium. The image decoding device includes: a decoding unit configured to generate a residual block of a current block by decoding a bit stream; a reference frame buffer for storing a reference frame; a motion compensation unit configured to generate a prediction block by using the reference frame and a motion vector of the reference frame; and an adder for adding the residual block and the prediction block. The image-decoding method comprises the following steps: clipping a motion vector ofa reference frame with a predetermined dynamic range so as to generate a clipped motion vector, wherein the scaling of the motion vector of the reference frame is performed based on a picture sequence count of the reference frame, the motion vector of the reference frame is a motion vector of a collocated block in the reference frame, and the collocated block is determined by performing the following operations: calculating a position corresponding to a lower right position of a current block in the current frame; and determining a block covering the calculated position in the reference frame.
