o Extended Integration Threshold (EIT)- Extended integration is when the
integration (shutter time) is longer than what is required to run the maximum
frame rate. The maximum frame rate varies depending on the camera model,
whether Binning and/or ROI are being used and whether using 8-bit or 16-bit
operation. This control is active when the camera is in both Auto Gain and Auto
Shutter and also is used when switching Binning modes to calculate the new
exposure when the camera exposure time is able to run into the extended period.
Best Image Quality end- The exposure control will extend integration time
out all the way to 500 milliseconds (if needed) before adding gain to achieve
the auto exposure level. This operation maintains the lowest possible noise
video signal however, may reduce the frame rate if the required exposure
ends up into the extended integration time.
Highest Frame Rate end- The exposure control will add all available gain (if
needed) before increasing the shutter time into the extended integration
period, thereby preserving the frame rate.
Values in between- Allows a portion from 0% (Best Image Quality) to 100%
(Highest Frame Rate) of maximum available gain to be used (if needed)
before increasing the Shutter time into the extended integration period.

Color Toolbar/Toolbox- (Color Cameras) These controls adjust individual color gain
controls for setting white balance. The Gain gauge (& number) shown in the Toolbar
(empty/0 to full/100) is a representation of the min to max range. The actual gain in
dB is displayed in the Status Bar. These controls can be set in one of three ways:
o Manual- In this mode, the user can adjust the individual color gains either
through the Color Toolbox or the Red, Green and Blue gain Toolbars. The
Histogram is a useful tool for manual white balancing. It provides individual
RGB image values which can be used to assist in the balancing of colors.
o One Push- The user can have the camera do the color balance by placing a
white scene in front of the camera and clicking the One Push button. It is
desirable to have the camera in "Auto Shutter" and/or "Auto Gain" to be sure
the image is correctly exposed. The routine can take a few seconds to
complete depending on the shutter time used. The RGB gains are saved in
the camera until another One Push routine or another mode is selected.
o Auto- When Auto is selected, the camera continually white balances.
