AW00104701000 Image Acquisition Control

Basler scout light GigE 123

Setting the Absolute Exposure Time Parameter

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 );

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 25.

9.8 Use Case Diagrams

For more information about standard mode and legacy mode and how to set them, see Section 9.1

on page 83.

The following pages contain a series of use case descriptions and diagrams. The descriptions and

diagrams are designed to illustrate how acquisition start triggering and frame start triggering work

in some common situations and with some common combinations of parameter settings.

These use cases do not represent every possible combination of the parameters associated with

acquisition start and frame start triggering. They are simply intended to aid you in developing an

initial understanding of how these two triggers interact.

This section assumes that the standard mode is enabled for image acquisition

control.

In principle, this section also applies if the legacy mode is enabled instead.

In this case, however, the following differences must be taken into account:

 the acquisition start trigger of the standard mode is not available in the legacy

mode.

 the frame start trigger of the standard mode is called "acquisition start trigger"

in the legacy mode.

When the camera is started for the first time after delivery from the factory the

image acquisition control will not be in standard mode but in legacy mode.

Use the legacy mode only if you want to operate the camera together with

previous cameras not featuring the standard mode.
