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
Feature Description
AcquisitionMode 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.
AcquisitionStart Starts the image acquisition of the camera.
AcquisitionStop Stops the image acquisition of the camera.
TriggerMode 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”.
ExposureMode Start or stop the internal exposure signal timer.
ExposureTime This feature is used to set the Exposure time (in microseconds).
ExposureTimeAbs This feature is used to set the Exposure time (in microseconds).
ExposureTimeGranularity Exposure time granularity
ExposureTimeAbsMs This feature is used to set the Exposure time (in milliseconds).
DarkTime This feature is used to set the Dark time (in microseconds).
DarkTimeAbs This feature is used to set the Dark time (in microseconds).
DarkTimeGranularity Dark time granularity
DarkTimeAbsMs This feature is used to set the Dark time (in milliseconds).

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.
