The Plateau Value specifies a limit to the number of pixels that can be associated
with a particular output count value.
2. Linear Histogram algorithm uses scene statistics to set a global gain and offset
(contrast and brightness) for the image. This AGC setting linearly adjusts the full 14
bit video bandwidth over the 256 levels of analog video displayed on the monitor.
3. AutoBright algorithm will automatically optimize the brightness as the scene varies.
AGC Parameters: The AGC Parameters allow for customization of each AGC type.
1. Plateau Value specifies a limit to the number of pixels that can be associated with a
particular output count. This value would apply regardless of the contents of the
scene. It acts to spread the pixel count over bins below and above the bin that has a
higher pixel count than the Plateau Value parameter allows. The lower the value, the
fewer pixels are allowed to be in a given bin, resulting in a darker image
2. Mid ITT Offset helps reduce the artificial darkness of the image due to a small max
gain value. The lower the value, the darker the image.
3. Max Gain allows control of the noise in the image. If the dynamic range of the scene
is low then a larger max gain will cause a nosier image.
Setup Control
TVIS-7º Setup Control
Save Settings: The Save Current Settings to Power On Defaults will save all settings defined in
the User Interface. The TVIS-7° will default to these settings upon power-up.
