Exposure control

Exposure time and dark time can be controlled using the features from the
branch AcquisitionControl of the GigE Vision feature tree.
tbd: More detailed explanation of timing constraints (regarding frame rate and
exposure time) of the individual camera models.
AcquisitionControl
Description
This feature controls the acquisition mode of the software. This
feature works independently (!) of the chosen camera mode
(Continuous, IOD hardware trigger, IOD hardware timer). It
describes how many frames should be acquired.
Starts the image acquisition of the camera.
Stops the image acquisition of the camera.
Modifies the trigger mode of the camera. When the trigger mode
is "Off", the camera will generate frames independently. When
the trigger mode is "On" the camera is switched to the so called
IOD (Image On Demand) mode. In this mode the camera waits for
an external trigger signal or an timer pulse generated internally.
To control exposure and dark time trigger mode must be switched
to "On".
Start or stop the internal exposure signal timer.
This feature is used to set the Exposure time (in microseconds).
This feature is used to set the Exposure time (in microseconds).
Exposure time granularity
This feature is used to set the Exposure time (in milliseconds).
This feature is used to set the Dark time (in microseconds).
This feature is used to set the Dark time (in microseconds).
Dark time granularity
This feature is used to set the Dark time (in milliseconds).
Table 12: Camera standard feature: AcquisitionControl
Note Bigeye P-132, Bigeye P-1100: The TriggerMode feature has to
be set to On and the timer has to be enabled via ExposureMode

in order to control the exposure.
