Abstract: A method and apparatus for editing continuous tone digital images representing pixels in which regions containing defects, called "defect regions", are unnoticeable or less visually discernible. Corrected pixel data for pixels in the defect region, called defect pixels, in the digital image are provided while data representing non-defect pixels outside of the defect region are not altered. These digital images may have one color channel (gray side) or multiple color channels. The apparatus and method includes a computer system which operates according to a set of instructions.

Abstract: A method of correcting one or more defect pixels in a defect region of a source image, which image has both the defect pixels and non-defect pixels each of which is represented by at least one defect pixel signal and non-defect pixel signal, respectively. The method comprises:a) searching for edges in a non-defect region of the image adjacent to the defect region by: (i) comparing relative pixel parameters in the non-defect region with a predetermined tolerance to locate a sequence of pixels representing an edge segment the members of which have relative parameters within the tolerance and which sequence is within a predetermined distance of the defect region; and (ii) comparing the length of an edge segment with a minimum length to identify as an edge a segment with at least the minimum length;b) generating at least one pixel signal for the defect region based on the signal of at least one non-defect pixel lying in a direction from the defect pixel which is determined by the direction of an edge.
