Abstract

A system and method for correcting defects in images. A secondary defect map, defining heavily damaged portions of the image which were not corrected automatically, is generated. The secondary defect map allows the user to correct the defects by highlighting the uncorrected areas. Once the secondary defect map is generated, if the user selects the defect, it is filled in with a correction value obtained from surrounding “good” pixels only, rather than all the pixels—corrected and uncorrected—in a surrounding area.
