ABSTRACT:
A circuit for restoring an image signal using motion compensation is disclosed, which includes an index address generator for storing and selectively generating a start address for each image, an adder for adding the start address generated by the index address generator to an address of a current macroblock to be processed and generating a pseudo address, an address calculator for calculating an address displacement from a motion compensation vector, and an address generator for adding said pseudo address to the address displacement to generate start and end addresses.
