ABSTRACT:
An image correction apparatus1includes an image input device3, a memory device4, a central processing unit2, and and image output device5. In the image correction apparatus1, a locally wrinkled document or a document with a binding portion lifted differently between the top and bottom of the document is read from the image input device3and, using a program which is run on the central processing unit2, an input image is corrected for the geometric distortion and luminance variations caused due to the upper and lower sides of the document making a slope with respect to a document platen, and thereby, a flat document image is restored.
