Abstract
The present disclosure relates an image correction apparatus and method. The image correction apparatus includes a printing unit for printing an image; a scratch detecting unit which detects a scratch region from a scan image scanned per line; and a restoration processing unit which performs the restoration of the scratch region by interpolation if the width of the scratch region detected by the scratch detecting unit is less than a predetermined value and, if the width thereof is not less than the predetermined value, does not perform a restoration of the scratch region but provides the printing unit with the scan image, thereby correcting an image distortion by easily detecting an image distortion due to foreign matter.
