Exposure Toolbar/Toolbox - DAGE-MTI Excel Series User Manual

•
Exposure Toolbar/Toolbox- Controls the camera's Exposure by allowing manual or
automatic Gain and Shutter settings and the priority of those settings.
o Exposure- The Exposure control creates a set point that the Auto Shutter and/or
Auto Gain controls use to establish an output video level. Both Shutter and Gain
are used to determine the video level; Shutter by controlling the amount of time
that light is gathered by the sensor, and Gain applied to the sensor's signal before
digitization. When the Exposure control is in Automatic, the Exposure level is
determined by the camera analyzing the video level to determine an ideal set
point. The Shutter and/or Gain automatics then set the output level to that point.
In the Manual Exposure mode, the video set point is determined by the user
adjusting the Exposure control. Exposure can be adjusted or put into automatic
mode from the Exposure Toolbox or the Exposure Toolbar. The Exposure gauge
(& number) shown in the Toolbar (empty/0 to full/100) is a representation of the
minimum to maximum range. The Histogram Toolbox and the highlighter to view
Saturated Pixels can be very useful tools for setting correct exposure.
o Gain- The Gain control can be used to provide gain (amplification) to the sensor's
output signal. In Auto Gain mode, the camera automatically determines the Gain
to achieve a correctly exposed image in accordance with the Exposure control.
The Auto Gain control is deactivated at Shutter times in excess of 500
milliseconds. Gain can be adjusted or put into automatic mode from the Exposure
Toolbox or the Gain Toolbar. The Gain gauge (& number) shown in the Toolbar
(empty/0 to full/100) is a representation of the minimum to maximum range. The
actual gain in dB is displayed in the Status Bar.
o Shutter- The Shutter control determines the length of time in which the CCD
sensor is exposed. Shutter times of 1ms-to-500 milliseconds are controlled via the
Shutter Toolbar, while in the Exposure Toolbox; the Shutter time can be extended
to 60 seconds. In Auto Shutter mode, the camera automatically determines the
shutter time to achieve a correctly exposed image in accordance with the
Exposure control. Auto Shutter is limited to 500 milliseconds. Longer Shutter
times require the camera to operate in the manual Shutter mode. The Shutter can
be adjusted or put into automatic mode from the Exposure Toolbox or the Shutter
Toolbar. The Shutter gauge (& number) shown in the Toolbar (empty/0 to full/100)
is a representation of the 1ms-500ms range. The actual shutter time is displayed
in the Status Bar.
