Configuration and Operation
Similarly, utilizing gain and increasing its level increases the sensitivity of the image sensor, which
brightens the image and add details. This increases the level of noise in the image.
In Manual Mode, the administrator can select a fixed shutter speed and gain from drop-down menus. The
smaller the shutter speed number (the higher the shutter speed), the lower the exposure level. The higher
the gain, the brighter the picture.
The following settings are available:
·
Shutter Speed – Select the fixed shutter speed according to the environmental luminance. The
following table lists the options:
·
Iris Size – The iris size is adjustable from 0 to 9 or Full Open. The higher the iris size, the lower
the shutter speed should be.
·
Gain – A nominal video signal level is usually 1-volt peak-to-peak for composite video, 0.7 volts for
component or RGB video, or 0.3 volts for the chrominance subsection, at which level a fully
saturated picture is transmitted to the acceptor. However, for cases where the video signal is
attenuated, a low-noise, high-gain analog amplifier is built into quality video processing equipment.
This amplifier provides video gain control whereby the video signal can be boosted or reduced. Dark
pictures caused by low level lighting are easily adjusted. The Gain drop-down menu turns the video
gain Off or moves it in steps from 1 to 9.
