Abstract
A device that performs automatic red-eye correction on a digital image saves the original image data and a location indicator from each portion of the digital image on which red-eye correction is performed to facilitate the subsequent undoing of red-eye correction. Red-eye correction may be undone at any time after red-eye correction has been performed by replacing the corrected image data with the original image data that is stored with the corrected digital image, and the device on which red-eye correction is undone may be distinct from the device that captured the digital image and from the device that performed red-eye correction on the digital image.
