Iris Adjustment; Internal (Electronic) Adjustments - CEI Color Six Operator's Manual

Iris Adjustment

The manual iris adjustment is the center control on the lens.
The iris must be set properly in order for the wide range
automatic gain in the Color Six to accommodate the greatest
range of contrast and brightness. To set the iris,
1. Open the iris as far as possible without causing flare in the
picture. Flare will appear as a halo or glare surrounding
bright objects.
2. Adjust the iris control to give the system as much light as
possible without discernable glare. This will assure the least
video noise in the output.
If the output video shows appreciable noise, verify that the
iris is properly adjusted.

Internal (Electronic) Adjustments

When the Color Six video assist camera is operated in the
AUTO mode, all electronic adjustments are set either to
default values or automatically adjusted for normal video
with average lighting. No menus or messages (beyond the
startup screen) will appear on the LCD monitor or in the "B"
video output. This may be the desired mode of operation in
most cases, but the operator can customize all the important
adjustments should it seem necessary or desirable. In many
respects, the utility of the Color Six is greatly enhanced in
MANUAL operation.
All electronic adjustments are made using the single multi-
purpose control shown in Figure 2.
