12.5 Sequencer
The sequencer feature allows to apply specific sets of configuration parameter settings, called
sequence sets, to a sequence of image acquisitions. As the images are acquired, one sequence
set after the other is applied. This makes it possible to respond to different imaging requirements
and conditions, that may, for example, result from changing illumination, while a sequence of
images is acquired.
Three sequence advance modes provide different schemes for advancing from one sequence set
to the next (see below for details).
The Sequencer and the Active Configuration Set
During operation, the camera is controlled by a set of configuration parameters that reside in the
camera’s volatile memory. This set of parameters is known as the active configuration set or "active
set" for short. When you use the pylon API or the pylon Viewer to make a change to a camera
parameter such as the Gain, you are making a change to the active set. And since the active set
controls camera operation, you will see a change in camera operation when you change a
parameter in the active set. For more information about the active set, see the "Configuration Sets"
section.
The parameters in the active set can be divided into two types: "non-sequence" and "sequence"
parameters (as shown in Figure 73 on page 242). The values of the non-sequence parameters
cannot be changed using the sequencer feature. The values of the sequence parameters, however,
can be set very quickly by using sequence sets: Because the sequence sets reside in the camera,
you can replace the values in the active set with values from one of the sequence sets almost
The sequencer feature will not work if the auto functions feature is enabled.
For more information about the auto functions feature, see Section 12.9 on
page 287.
This section assumes that the standard mode is enabled for image acquisition
control. We strongly recommend to use the standard mode when using the
sequencer feature and avoid using the legacy mode.
For more information about the standard mode, see Section 8 on page 91.
If the sequencer feature is not available, activate the "Full" camera description file.
For more information, see Section 12.19 on page 325.
