High Dynamic Range (HDR) feature
Matrix 320 supports the High Dynamic Range (HDR) feature. HDR  performs an image
dynamic  correction  where  low  intensity  pixel  values  are  enhanced,  thus  improving
image contrast and code readability. 
This feature proves particularly useful in the following cases:
• To adjust contrast when the outer area of the image is less exposed than the cen-
tral area because of a large Skew angle:
• To adjust contrast at the FoV edges when illumination is not homogeneous. The 
HDR feature helps normalize image contrast allowing the use of Standard Contrast
