Abstract
The present invention concerns a method and associated apparatus for improving the quality of digital imagery by detecting and correcting erroneous pixel values from image sensors, such as those produced by stuck or dead pixels in a CCD or CMOS sensor. Anomalous pixel values are detected through comparisons with values of adjacent pixels and corrected selectively per channel through interpolation of adjacent pixel values.
