BLC - configurable Back Light Compensation

BLC reduces a phenomenon observed on the images recorded by the cameras positioned directly in front of a high-intensity light source.

 

In the image recorded in front of a high-intensity light source, the foreground is dark and not clearly visible. BLC makes the image brighter, sharper and the objects in the foreground more easily recognisable. As a result, the contours of the objects are more pronounced and can be easily identified.

 

BLC is also immune to noise, and can use automatic detection and image correction, however, the background is usually significantly brightened.
