Abstract
An image processing device for processing an image read by an image scanner or similar image reading device is disclosed. The image processing device is capable of accurately detecting, without resorting to a range finding sensor or similar special sensing means, the bound portion of a spread book by recognizing the configuration of the bound portion out of a read image, and thereby accurately correcting the distortion of the portion of the image representative of the bound portion.
