2.3. Lens option
The lens control is pre-set to DC.
By pressing the joystick, a menu pops up. You can then adjust the brightness (0–70). Press
the joystick again to save your settings.
2.4. Exposure
Shutter:
The flickerless mode (FLK) reduces picture flickering.
AGC (Automatic Gain Control):
Automatic gain control to adjust the brightness (high, medium, off). The brightness can
be re-adjusted.
Sens-Up:
OFF or AUTO. In auto-mode you can select values from 2x to 256x in order to achieve a
better picture under low light conditions or in darkness. Noise may occur. This function
can be de-activated if the shutter is set to FLK mode.
2.5. White balance
ATW:
Auto Tracking White Balance for colour temperatures of 1800°K to 10500°K.
Indoor:
For colour temperatures of 4500°K to 8500°K.
Outdoor:
For colour temperatures of 1800°K to 10500°K.
AWC -> Set:
Auto White Balance Control. Automatic white balance if you hold a white sheet of paper
infront of the camera and press the joystick (sufficient light conditions required).
Manual:
The red and blue values can manually be set.
2.6. Backlight
BLC:
If the lens is exposed to strong backlight, you can activate the „backlight“ function in
order to achieve a clear picture of both the object itself and the background.
HLC:
Highlight Compensation. Highlights in the picture can be deleted which makes the
picture sharper.
2.7. DNR (Digital Noise Reduction)
Noise can be reduced. If the DNR value is increased and thus the noise is reduced, artefacts
may occur.
If AGC is switched off, the DNR function is off, too.
