Image detector defective pixel image detection/replacement has sweep charges line generated/integrated and stored with second repetition and comparison finding replacing defective addresses and process line sequenced.
Image detector defective pixel image detection/replacement has sweep charges line generated/integrated and stored with second repetition and comparison finding replacing defective addresses and process line sequenced.
The defective pixel detection and correction technique has an M asterisk N pixel image detector (20). Photoelectric charges are generated over a first pixel line and integrated and stored. A second sweep and integration is then carried out. The first and second digital words are compared, and if the outputs are different store an elementary pixel as a defective pixel address. The process is repeated for the other lines. Where defective addresses are found, corrected digital words are generated.
