Setting the Exposure Time Using Basler pylon
If you are parameterizing the camera with Basler pylon, the exposure time is determined by the
setting of the Exposure Time Abs parameter. The Exposure Time Abs parameter sets the exposure
time in µs. The exposure time should be set in increments of 1 µs.
You can use the pylon API to set the Exposure Time Abs parameter value from within your
application software. The following code snippet illustrates using the API to set the parameter value:
// Set the exposure time to 1000 µs
Camera.ExposureTimeAbs.SetValue( 1000 );
You can also use the Basler pylon Viewer application to easily set the parameter.
For more information about the pylon API and the pylon Viewer, see Section 4 on page 45.
Setting the Exposure Time Using Direct Register Access
If you are parameterizing the camera via direct register access, the Exposure Time Raw register
sets the exposure time.
To set the exposure time via direct register access:
 Set the value of the Exposure Time Raw register.
A value in a raw register is simply an integer value with no units. To determine what the actual
exposure time will be, you must multiply the value in the raw register by the camera’s time base.
The time base on aviator cameras is 1 µs.
For example, if you set the Exposure Time Raw register to 1000, the exposure time would be
1000 µs (1000 x 1 µs = 1000 µs).
For more information about changing settings via direct register access, see Section 4 on page 45.
