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.
