Abstract
An image processing device includes an image acquiring unit, a storage unit, and an image processing unit, wherein the image region is divided into a plurality of sub-regions in the vertical direction, and wherein when the rectangular range set in the image region extends over two or more sub-regions, the image processing unit acquires the cumulative value at a pixel position in the lowermost sub-region of the two or more sub-regions by adding the cumulative values in the upper sub-regions at the pixel position in the same column of a lowermost row in the upper sub-regions, over which the rectangular range extends, to the cumulative value in the lowermost sub-region at the pixel position in the lowermost sub-region.
