摘要：Disclosed is a motion estimation apparatus and method capable of reduce amemory bandwidth by accessing reference image data occupying the largest part of thememory bandwidth based on a result of motion estimation skip determination. Themotion estimation apparatus includes a motion estimation skip determination unit, a sum

absolute of absolute difference (SAD) processing unit and a multiplexer (MUX) unit. Themotion estimation skip determination unit determines the presence of motion estimationskip by reading current image data and skip reference image data, and outputs a motionvector in a skip mode. The SAD processing unit calculates an SAD value by reading thecurrent image data and reference image data and outputs a motion vector in a normalmode. The MUX unit outputs the motion vector in the skip mode or the motion vector inthe normal mode as a final motion vector based on a skip flag signal.
