A process and apparatus which corrects defective pixels in radiation detector arrays, specifically bad pixel lines along a common electrode.

A limited number of adjacent pixel lines are identified as bad pixel lines, and preferably the window subdivided (5) , into smaller windows along the bad pixel lines with good pixels in each , subdivision being used to calculate correction coefficients (10) for correcting the pixels (13) in the original bad pixel line and the adjacent bad pixel lines.

Why it's free to use
- Filed February 10, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 10, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 10, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
