–

Off: turns off all automatic scene detail and enhancements 

(only recommended for testing).

–

XF Dynamic: extra internal processing is enabled for low-

light applications (traffic, etc.). 

–

Smart BLC: BLC window and weighting factor are 

automatically defined. Camera dynamically adjusts these 

for changing light conditions.

Auto black ON automatically increases the visibility of details 

even when scene contrast is less than full-range due to mist, 

fog, etc.

Adjusts the black level between -15 and +15. Zero position of 

slider corresponds to the factory default black level.

A low (negative) value makes the picture less sharp. Increasing 

sharpness brings out more detail. Extra sharpness can enhance 

the details of license plates, facial features and the edges of 

certain surfaces.

In AUTO mode the camera automatically reduces the noise in 

the picture. This may cause some motion blur on exceptionally 

fast moving objects immediately in front of the camera. This can 

be corrected by widening the field of view or selecting Off.
