Abstract
A method of estimating motion in a mobile device reduces access of external memory and power consumption while increasing the usability of internal memory. The method includes recognizing an overlapped block of a reference search area between the current and its next macro block, and transferring only non-overlapped blocks to internal memory when motion estimation of a next macro block is performed.
