The inclination angle represents an inclination angle of the edge of the document with respect to a first reference direction and a second reference direction perpendicular to the first reference direction. The correction method further includes correcting the inclination angle of image data of the document with respect to the first and second reference directions. The step of the correcting includes a shift processing conducting a first shift processing in which the image data are shifted to one of the first and second reference directions according to the inclination amount and conducting a second shift processing in which the image data are shifted to the other of the first and second reference directions according to the inclination amount.
