10.8 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. Since the active set
controls camera operation, you will
see a change in camera operation
when you change a parameter in
the active set.
The parameters in the active set
can be divided into two types
(Figure 96):
"non-sequence" parameters:
Cannot be changed using the
sequencer feature.
"sequence" parameters:
Because the sequence sets reside in the camera’s FPGA, you can replace the values in the
active set with values from one of the sequence sets almost instantaneously as images are
acquired.
The sequencer feature will not work, if the auto functions feature is enabled. For
more information about the auto functions feature, see Section 10.13 on
page 276.
