Manually Setting the Overlap Mode of Operation

(daA1280-54bm/bc, daA1600-60bm/bc)
On daA1280-54bm/bc and daA1600-60bm/bc cameras, you can use the OverlapMode parameter
to manually disable or enable overlapping image acquisitions.
If the OverlapMode parameter is set to
On, the sensor is put in the overlap mode of operation. The camera will automatically overlap

exposures and readouts in the free run mode.
Off, the sensor is put in the non-overlap mode of operation. The camera will never overlap

exposures and readouts. This can improve image quality, especially when you are operating
the camera at low frame rates.
For more information about the overlap and non-overlap mode of operation, see Section 9.5 on
page 73.
The following code snippet illustrates using the pylon API to set the OverlapMode parameter value:
// Set for the overlapping mode of operation
camera.OverlapMode.SetValue(OverlapMode_On);
// Set for the non-overlapping mode of operation
camera.OverlapMode.SetValue(OverlapMode_Off);

Table 30: Exposure Active Availability
Cameras with a global shutter imaging sensor provide an "exposure active" (ExpAc) output signal.
The signal goes high when the exposure time for each frame acquisition begins and goes low when
the exposure time ends as shown in
useful when you are operating a system where either the camera or the object being imaged is
movable.
