AW00123409000 Image Acquisition Control
Basler ace USB 3.0 135
For more information about the Frame Trigger Wait signal, see Section 6.8.4.2 on page 168.
You can use the Basler pylon API to set the ExposureOverlapTimeMax parameter value from within
your application software. The following code snippet illustrates using the API to set the parameter
value:
camera.ExposureOverlapTimeMax.SetValue( 3000.0 );
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 61.
Particular Implementation for Cameras with Exposure Overlap Time Modes
For acA640-750, acA800-510, acA1300-200, acA1920-40, acA1920-150, acA1920-155,
acA2040-55, acA2040-120, acA2440-35, acA2440-75, and acA2500-60 cameras, you can choose
between Exposure Overlap Time Modes:
If you set the Manual mode, use of the Frame Trigger Wait signal is strongly recommended to
avoid overtriggering. To use the Frame Trigger Wait signal, you must set the Exposure Overlap
Time Max parameter, described in the preceding section.
If you set the Automatic mode, the camera will automatically use the maximum possible
overlap time for each acquisition. The Automatic mode will be particularly useful with long
exposure times. Note that the Frame Trigger Wait signal is not available when the Automatic
mode is selected. The Automatic mode is the default mode.
You can use the Basler pylon API to set the Exposure Overlap Time Modes and the Exposure
OverlapTimeMax parameter value from within your application software. The following code snippet
illustrates using the API to set the parameter values:
// Set (and read) the Manual mode for the ExposureOverlapTimeMode
// and set an ExposureOverlapTimeMax parameter value
camera.ExposureOverlapTimeMode.SetValue(ExposureOverlapTimeMode_Manual);
ExposureOverlapTimeModeEnums e =
camera.ExposureOverlapTimeMode.GetValue();
// Set an ExposureOverlapTimeMax parameter value
camera.ExposureOverlapTimeMax.SetValue( 3000.0 );
// Set (and read) the Automatic mode for the ExposureOverlapTimeMode
camera.ExposureOverlapTimeMode.SetValue(ExposureOverlapTimeMode_Automati
c);
ExposureOverlapTimeModeEnums e =
camera.ExposureOverlapTimeMode.GetValue();
You can also use the Basler pylon Viewer application to easily set the parameters.
