Patent abstract
A method and apparatus that allows for the identification and correction of defective pixels and/or pixel clusters in an imaging device. The method, and implementing apparatus determines that a pixel is defective based upon a comparison of its pixel signal value with the value of neighboring pixels. In one exemplary embodiment, a pixel is defective if it is beyond a pre-determined threshold of either a high or low value from its neighboring, corrected pixels. Pixels identified as defective can be corrected using exemplary methods of the invention such as substituting a value of the defective pixel with a value of one of its non-defective neighbors.
