3.4.1 Trigger
Each exposure is started by a signal connected to the EXPOSE input pins of the “Digital
Interface” connector on the rear panel of the camera. The exposure command sets the exposure
time and, indirectly, the frame rate.
The EXPOSE input sets the start time for each frame of video. When the trigger signal lasts
longer than the combined exposure and readout time, the camera will continue to take exposures
until the trigger signal goes away.
The trigger mode of operation is used to capture a single picture or sequence of pictures. If the
object that you are trying to capture is fast moving, a strobe light may be used to freeze the
action. The short flash duration (sometimes less than 50 microseconds) of a strobe is the key to
minimizing blur caused by speedy subjects. The Strobe Output on the rear panel of the camera
can be used to start the strobe flash.
3.4.2 Continuous
The continuous mode of operation is useful when the operator wishes to monitor an ongoing
event. The camera will repeatedly take pictures as fast as the exposure time selected allows.
The exposure command sets the exposure time and, indirectly, the frame rate. Each new
exposure starts as soon as the previous image has been transferred to the camera output by the
camera electronics.
3.4.3 Control
The start and exposure time of each picture is controlled directly by the user. Control is
accomplished by the EXPOSE input pins in the “Digital Interface” connector on the rear panel of
the camera. The exposure time is equal to the time the EXPOSE input signal is true.
3.4.4 Parallel Interface
This option provides compatibility with previous models of the
Mega Plus Camera. This mode
enables limited camera control by a frame grabber board installed in a host computer. When the
mode is set to Parallel Interface, the state of the control lines MC0, MC1, and MC2 determines
the operating mode of the Camera. See page 4.2 for details on control lines MC0 - MC2.
