Defect pixel correction (ICategory: DefectPixel)

6.10

In Quartz series cameras defect pixels are corrected in real time.

Adimec does not release cameras with more than 1 adjacent defect pixel upon delivery. However,
additional defect pixels can be user-programmed.

Up to 2 adjacent pixels can be corrected. More than 2 adjacent defect pixels can be user
programmed, but will not result in a reliable correction.

Correction is done by interpolation of the adjacent pixels according to the method illustrated in figures
6.4 and 6.5.

The defect pixel list has a capacity of 500 pixels.

Defect pixel correction method on monochrome cameras.

Find below the list of all commands related to the defect pixel correction. In the next subsections they
are explained in more detail.
