Abstract
A book scanner which reads an image of a book or a bound document placed as turned upward, computes the document inclination from the outer shape of the document, detects the top end of the bound part of the document from the document height, thereby determines the accurate position of the center line existing in a slanted posture, detecting the brightness in the neighborhood of the bound part, thereby computes the erasing width to be erased as unnecessary for an image with precision, and erases only the center line zone without failing to effect thorough erasure of the slanted center line.
