ABSTRACT:
Provided are a moving picture encoding apparatus having an increased encoding speed, and a method thereof, where the moving picture encoding apparatus includes a first frame memory storing an input image divided into brightness blocks of current macroblocks, each stored in one page; a second frame memory storing a previous image divided into clusters, each including brightness blocks of a predetermined number of macroblocks and being stored in one page; a motion estimation processor reading a brightness block of a current macroblock from the first frame memory, reading a cluster corresponding to a search area of the current macroblock from a search area of the second frame memory, and calculating a motion vector of the brightness block of the current macroblock on the basis of the read brightness block of the current macroblock and the read cluster; and a motion compensation processor reading a brightness block of a macroblock, which is moved by reflecting the motion vector on the current macroblock, from the second frame memory.
