AW00049313000 Acquisition Control
Basler runner 95
You can set the Exposure Time Raw and Exposure Time Base Abs parameter values from within
your application software by using the pylon API. The following code snippet illustrates using the
API to set the parameter values:
Camera.ExposureMode.SetValue( ExposureMode_Timed );
Camera.ExposureTimeRaw.SetValue( 2 );
Camera.ExposureTimeBaseAbs.SetValue( 25.0 );
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.
Setting the Exposure Time Using "Absolute" Settings
You can also set the exposure time with an "absolute" parameter. This is accomplished by setting
the camera’s Exposure Time Abs parameter. The unit for the Exposure Time Abs parameter is µs.
The increment for the Exposure Time Abs parameter is determined by the current setting for the
Exposure Time Base Abs parameter. For example, if the time base parameter is currently set to
62.0 µs, you could set the Exposure Time Abs parameter to 62.0 µs, 124.0 µs, 186.0 µs, etc.
Note that if you set the Exposure Time Abs parameter to a value that is not a multiple of the
Exposure Time Base parameter, the camera will automatically change the setting for the Exposure
Time Abs parameter to the nearest multiple of the time base parameter.
You should also be aware that if you change the exposure time using the raw settings, the Exposure
Time Abs parameter will automatically be updated to reflect the new exposure time.
You can set the Exposure Time Abs parameter value from within your application software by using
the pylon API. The following code snippet illustrates using the API to set the parameter value:
Camera.ExposureTimeAbs.SetValue( 124.0 );
double resultingExpTime = Camera.ExposureTimeAbs.GetValue( );
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.
Note
The setting for the Exposure Time Abs parameter must be between the
minimum and the maximum allowed values (inclusive) shown in Table 7 on
page 91.
