Patent ID: 7932938

Claim:
A method of adjusting a pixel array defect map comprising: storing an initial pixel defect map corresponding to a pixel sensor array; obtaining pixel output signals from said pixel sensor array; using said pixel output signals to determine current defective pixel locations in accordance with pixel defect criteria; for every current defective pixel location: if the corresponding location in the stored pixel defect map was previously marked as defective, comparing the data of the corresponding location in the stored pixel defect map with the data of said respective current defective pixel location, updating the mark for the corresponding location in the map to indicate a true defect if the compared stored data is the same as the compared current data, and removing the defect mark for the corresponding location in the map if the compared stored data is different from the compared current data; and if the corresponding location in the map was not previously marked as defective, marking the corresponding location in the map as defective; and storing the pixel defect map.
