*
* Depending of the sensor quality, some pixels can be defective and then
* appear significantly brighter or darker than the other pixels.
*
* The Defect Pixel Cluster Correction algorithms is responsible to minimize
* the impact of the pixels. This can be done with algorithms applied at run
* time (on-the-fly method) or with a table of defective pixels. Only the first
