Abstract

An apparatus and method for processing digital images having eye color defects. In one method for detecting and correcting eye color defects of a subject in a digital image, the steps comprise: (a) processing the digital image to automatically detect one or more candidate positions of eye color defects in the digital image; (b) automatically applying an eye color defect algorithm to the digital image at the detected candidate positions to automatically correct for the eye color defect; (c) displaying, on a display, at least a portion of the digital image comprising at least one of the corrected eye color defects; and (d) displaying, on the display, an indicator located proximate the at least one of the corrected eye color defects indicative of the at least one of the corrected eye color defects.
