情報動き補償装置。 A device that compensates for motion when encoding image information, which comprises a previous frame memory that stores image information of a previous screen, a current frame memory that stores image information of a current screen, and the current frame memory or the previous frame. A small block address setting device that divides either one of the memories into blocks of a predetermined size and specifies an address for reading one of the blocks, and a device that supports parallel and rotational movement with respect to the address set by the small block address setting device. an address conversion device that specifies and reads out the other of the previous frame memory or the current frame memory by address conversion; and an approximation comparison device that compares the degree of approximation between the previous frame memory and the current frame memory based on image information of the previous frame memory and the current frame memory; An image information motion compensation device comprising: a threshold setting device for setting a degree of approximation; and a quantization device for quantizing a result of approximation comparison.
