Abstract
An image acquiring unit reads an original and outputs whole image data of the original including a vertical streak portion corresponding to a location of a foreign material on a read surface of the reading unit. A storing unit stores therein the image data output from the image acquiring unit. A dividing unit defines an edge portion of the image data and divides the image data into vertical-streak-correction subject data and image portion data. A vertical-streak correcting unit performs a correction process on the vertical-streak-correction subject data to compensate a degradation in image quality due to the foreign material.
