Abstract
An apparatus, system, method, and computer program product is disclosed, each capable of correcting distortion in a scanned image, using at least a character line extracted from the scanned image. The character line is extracted based on a circumscribed rectangle, representing the vertical component of the character. The distortion in the scanned image is corrected based on the length of the circumscribed rectangle in the main scanning direction.
