3. SENSE UP
(AUTO, OFF) : If only a very poor illumination is available,
the light sensitivity of the camera can be increased. The shutter time is
extended so that the exposure time covers several pictures. In the line
SENSE UP it is possible to select if the sensitivity should be increased
(ON) or not (OFF). If On has been selected, adjust the factor for the
exposure time (X2, ….X1024)
2. AGC
(OFF, LOW, MIDDLE, HIGH) : If the illumination is poor, the video
signal is amplified accordingly by the automatic gain control (AGC).
The value AGC in the submenu EXPOSURE defines the control range.
A high amplification increases the picture brightness; however, a higher
picture noise is created as well.
OFF: Deactivates the AGC function
LOW, MIDDLE, HIGH : Adjust AGC level
