Abstract
A high-speed motion estimation apparatus includes a current region memory, an integer-times motion estimation unit, and a decimal-times motion estimation unit. The current region memory receives pixel data of a current region from an external frame memory to store the pixel data. The integer-times motion estimation unit stores pixel data of an estimation region which are read from the frame memory, and predicts an integer-times motion vector by using the pixel data of the current region and the pixel data of the estimation region. The decimal-times motion estimation unit reads the pixel data of the estimation region, and predicts a decimal-times motion vector by using the read pixel data and the predicted integer-times motion vector.
