An image processing apparatus which includes an image reading apparatus comprising a first memory, a book image corrector, and a selector. The first memory stores optical positioning information of the image reading apparatus. The book image corrector performs an image correction based on reference data from an image read by the image reading apparatus when the image is of a book document. The selector selects one of the plurality of different correction modes of the second corrector based on the optical positioning information stored in the first memory. The book image corrector includes a first corrector configured to correct in a main scanning direction a distortion of the image of the book document based on the reference data and a second corrector having a plurality of different correction modes configured to correct a distortion of the image of the book document in a sub-scanning direction.
