Abstract
The present invention provides a technology that is implemented in a motion compensation image coding device or a coding method and intended to code motion picture data in real time by performing a decreased number of arithmetic operations so as to determine a motion vector. In motion compensation image coding, macroblocks and sub-blocks into which each of the macroblocks is divided are searched for a motion vector with integer pixel precision. Based on the results of the search, a shape of a block that should be searched for a motion vector with decimal pixel precision is determined as a shape mode. The block of the shape mode is searched for a motion vector with decimal pixel precision, whereby a motion vector needed to produce predictive image data is determined.
