Table 17 : Pixel Correction GeniCam names
The camera will re-calculate the pixel coordinates according to sensor mirror options, sort the
coordinates in ascending order and write them to hardware memory. It will also specify the total
number of pixels to be corrected.

Flat field
To make Dark/Flat field correction, two pictures should be taken. One with lens closed (offset
should be boosted) and one with uniform illumination of around 40%.
There will be TBD tables stored in the camera (For each gain, temperature, etc,).
The operator is per pixel and defined according to following formula:
𝑃(𝑥, 𝑦) = 𝐺𝑎𝑖𝑛(𝑥, 𝑦)[𝑃(𝑥, 𝑦) − 𝑃
𝑑𝑎𝑟𝑘
(𝑥, 𝑦)]
