ABSTRACT:
The present invention is related to methods and systems for detecting defective imaging array pixels and providing correction, thereby reducing or eliminating visible image artifacts. One embodiment of the present invention provides an on-line bad pixel detection and correction process that compares a first pixel readout value with a first value related to the readout values of other pixels in first pixel's local neighborhood. When the first pixel readout value varies by more than a first amount as compared with the first value, a second value related to the readout values of the neighboring pixels is used in place of the first pixel readout value.
