<p>PURPOSE: To shift the block which is small in hardware scale and is composed of n×m picture elements by an (n) picture element unit at high speed. CONSTITUTION: When a motion compensation is performed for every block BK by an image decoder such as an MPEG, etc., a register 43 stores the number SF of shift of picture element to be shifted based on a motion vector. The image information read from a frame memory by an (n) picture element unit is made a write inhibition state in a WE mask pattern generation part 41 and an AND gate 42, the image information is not shifted and the information is stored in a block buffer 31. When reading out, a reading address is shifted by the number of shift of picture element SF by an adder 1414, and the image information is read out of the block buffer 31 by a picture element unit.</p> |
