6 Acquisition Control

The sample code included in this section represents "low level" code that is
actually used by the camera.
Many tasks, however, can be programmed more conveniently with fewer lines of
code when employing the Instant Camera classes, provided by the Basler pylon
C++ API.
For information about the Instant Camera classes, see the C++ Programmer's
Guide and Reference Documentation delivered with the Basler pylon Camera
Software Suite.
This section provides detailed information about controlling the acquisition of image information.
You will find details about triggering line acquisition, about setting the exposure time for acquired
lines, about setting the camera's line acquisition rate, and about how the camera's maximum
allowed line acquisition rate can vary depending on the current camera settings.
The following elements are involved in controlling the acquisition of lines:
the line start trigger

exposure time control

Line Start Triggering

The line start trigger is used to start a line acquisition. Keep in mind that the camera will only react
to a line start trigger when the line start trigger is valid. If the line start trigger is invalid, line start
triggers will be ignored.
The first parameter associated with the line start trigger is the TriggerMode parameter. The
TriggerMode parameter has two available settings: off and on.
6.1.1

Line Start with TriggerMode = Off

When the trigger mode is set to Off, selection of a source signal for the line start trigger is not
required. With the trigger mode set to Off, the camera operates the line start trigger automatically
and generates the line start triggers internally.
