7.11.
DNR Control (Digital Noise Reduction)
The Digital Noise Reduction function reduces random noise by averaging multiple frames before outputting
an image. As the image is not output in real time, and the scene must not change while frames are being
averaged, this function is only recommended to use when the camera system is stationary.
Settings:
OFF, LOW, MED, HIGH
7.12.
Day/Night mode
This function allows the camera to operate in a night mode, with the possibility to output monochrome
video and switching to slow shutter (integration mode) for higher sensitivity.
In the AUTO setting, the camera will detect when to switch between Day and Night based on the brightness
of the scene. A hold time of between 1 and 60 seconds can be configured, to avoid erratic switching due to
small variations in scene brightness. The Luminance setting in AES influences the level of brightness for
switching between Day and Night.
When set to COMPUL, it is possible to externally switch between Day/Night modes via pins 6 & 7 on
connector J2. Default is Day mode when pins left open. Shorting pins 6 & 7 together sets Night mode.
When Day/Night mode is set to NIGHT or AUTO, and the function Colour Mode (7.16.) is set to AUTO, the
camera will also switch over to monochrome. See also "Sense Up Priority" under Special Functions menu.
Settings:
DAY, NIGHT, COMPUL, AUTO – Hold Time 1 to 60 sec.
7.13.
Fog Reduction
To correct for environmental influence from fog, haze, rain
or smoke, his function expands the mid-range part of the
camera response curve to provide higher contrast.
Settings:
OFF, LOW, MID, HIGH
NOTE:
Setting Fog Reduction to LOW, MID or HIGH forces Gamma
to 0.45 and turns off Eclipse Control (white peak inverter)
7.14.
Eclipse Control
Allows excessively bright areas in a scene to be rendered as
grey and therefore not adversely affect brightness control
systems in the camera.
Settings:
OFF, LOW, MID, HIGH
NOTE:
Setting Eclipse to LOW, MID or HIGH forces Gamma to 0.45
and turns off Fog Reduction.
