Abstract
A method of decoding images including the steps of: extracting motion vector information from input information to be decoded; synthesizing a prediction image by performing motion compensation using the motion vector information and a reference image which is a previously decoded image; and synthesizing a decoded image by adding the prediction image to an error image, wherein the motion compensation includes specifying either a positive rounding method or a negative rounding method for interpolating intensity values of pixels in performing the motion compensation.
