<p>A dividing circuit (11) divides input frames contained in input video (Vi) into a plurality of partial data items that do not overlap each other, and while switching the selection of partial data, outputs one partial data item for one input frame. A memory control circuit (14) writes partial data output from the dividing circuit (11) to a frame memory (15), and reads from the frame memory (15) reconstructed frames having the same size as the input frames and consisting of a plurality of partial data items that are based on the plurality of input frames that are mutually different. A combining circuit (19) combines the reconstructed frames read from the frame memory (15) and finds output video (Vo) containing the combined frames. As a result of the foregoing, without substantially reducing image quality, the access rate related to frame memory is reduced.</p> |
