11.10 Defect Pixel Correction

When analyzing your acquired images, some pixels may appear significantly brighter or darker than
the rest, even when uniform light is used ("outlier pixels"). This problem arises from sensitivity
differences among the pixels due to production tolerances.
The defect pixel correction minimizes the influence of these sensitivity differences. Basler dart
cameras can perform two types of pixel corrections:
The static pixel correction only corrects pixels that have a significantly lesser intensity value

than its neighboring pixels (or that are always completely black).
The dynamic pixel correction only corrects pixels that have a significantly greater intensity

value than its neighboring pixels.
You can specify which corrections should be performed by setting the DefectPixelCorrectionMode
parameter:
On (default): Static and dynamic pixel corrections are both enabled.

Off: Static and dynamic pixel corrections are both disabled.

StaticOnly: Only the static pixel correction is enabled.

You can set the DefectPixelCorrectionMode parameter by using the pylon API. The following code
snippet illustrates using the API to set the pixel correction:
// Disable pixel correction
camera.DefectPixelCorrectionMode.SetValue(DefectPixelCorrectionMode_Off);
// Enable static and dynamic pixel correction
camera.DefectPixelCorrectionMode.SetValue(DefectPixelCorrectionMode_On);
// Enable static pixel correction only
camera.DefectPixelCorrectionMode.SetValue(DefectPixelCorrectionMode_StaticOnly);
