  • Patent number: RE47004
    Abstract: The present invention relates to a A moving image coding apparatus and method involving the simultaneous parallel running of respective modules, namely: a segment-unit-coding module in which an input image frame is divided into segment units and the integer pel (integer pixel) motion is estimated while at the same time the 1/n pixel images are generated with respect to the segments of the image coded in the coding module; and a macroblock-unit-coding module in which the segments of the image frame whose the integer pel motion has been estimated in the segment-unit-coding module are received as input in the form of macroblock units and are coded in macroblock units through the 1/n pixel motion estimation. By separating the coding units into different modules and employing the techniques of parallel processing and pipelining, the present invention makes it possible to effect high-speed encoding with reduced delay in the coding rate due to differences in the processing speeds of the respective modules.
