Image Acquisition Control
Basler scout light 37
6 Image Acquisition Control
This section provides detailed information about controlling image acquisition. You will find details
about setting the exposure time for each acquired image and about how the camera’s maximum
allowed acquisition frame rate can vary depending on the current camera settings.
6.1 Controlling Image Acquisition with
Parameters Only (No Triggering)
You can configure the camera so that image acquisition will be controlled by simply setting the value
of several parameters via the camera’s API. When the camera is configured to acquire images
based on parameter values only, a software trigger or an external hardware trigger (ExTrig) signal
is not required.
You can set the camera so that it will acquire images one at a time or so that it will acquire images
continuously.
6.1.1 Switching Off Triggering
If you want to control image acquisition based on parameter settings alone, you must make sure
that the camera’s acquisition start trigger is set to off. Setting the acquisition start trigger is a two
step process:
First use the camera’s Trigger Selector parameter to select the Acquisition Start trigger.
Second use the camera’s Trigger Mode parameter to set the selected trigger to Off.
You can set the Trigger Selector and the Trigger Mode parameter value from within your application
software by using the pylon API. The following code snippet illustrates using the API to set the
selector and the parameter value:
Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );
Camera.TriggerMode.SetValue( TriggerMode_Off );
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon Viewer, see Section 3.1 on page 17.
