Abstract
This invention improves the image processing speed by implementing efficient access to a buffer memory while suppressing the access count. For this purpose, when transferring ith partial image data obtained from a first signal processing unit to a buffer memory, a data-transfer controlling unit transfers data out of the ith partial image data except the data of a region overlapping an immediately preceding (i−1)th partial image data to the buffer memory, and transfers the ith partial image data including the data of the overlap region to a subsequent second signal processing unit.
