Abstract
An image processor which corrects tilt of an input image without operator intervention. Projections of two partial images of an original are obtained at check points determined from input image information. A tilt angle of the original is obtained from a correction position of the projections of each partial area. The image is divided into belt-shaped small areas and shifted in accordance with the obtained tilt angle to form an image in which the tilt of the input image is corrected.
