Abstract
A division circuit 11 divides input frames included in an input video Vi into plural pieces of partial data that are not superimposed with each other and outputs one piece of partial data for one input frame while switching selection of the partial data. A memory control circuit 14 writes the partial data output from the division circuit 11 in a frame memory 15, and reads a reconstruction frame that is configured by plural pieces of partial data based on a plurality of input frames that are different from each other and has a same size as the input frames from the frame memory 15. A composition circuit 19 composites the reconstruction frame read from the frame memory 15, and obtains an output video Vo that includes a composited frame. Thereby, an amount of access to the frame memory is reduced without deteriorating image quality significantly.
