13.15 Sequencer Control 123
configured by a list of parameter sets. Each of these sequencer sets contains the settings for a number of camera
features. Similar to user sets, the actual settings of the camera are overwritten when one of these sequencer
sets is loaded. The order in which the features are applied to the camera depends on the design of the vendor.
It is recommended to apply all the image related settings to the camera, before the first frame of this sequence
is captured. The sequencer sets can be loaded and saved by selecting them using SequencerSetSelector. The
Execution of the sequencer is completely controlled by the device.

13.15.2 Configuration of a sequencer set
The index of the adjustable sequencer set is given by the SequencerSetSelector. The number of available se-
quencer sets is directly given by the range of this feature. The features which are actually part of a sequencer set
are defined by the camera manufacturer. These features can be read by SequencerFeatureSelector and acti-
vated by SequencerFeatureEnable[SequencerFeatureSelector]. This configuration is the same for all Sequencer
Sets. To configure a sequencer set the camera has to be switched into configuration mode by Sequencer←-
ConfigurationMode. Then the user has to select the desired sequencer set he wants to modify with the Sequencer←-
SetSelector. After the user has changed all the needed camera settings it is possible to store all these set-
tings within a selected sequencer set by executing SequencerSetSave[SequencerSetSelector]. The user can
also read back these settings by executing SequencerSetLoad[SequencerSetSelector]. To permit a flexible us-
age, more than one possibility to go from one sequencer set to another can exist. Such a path is selected by
SequencerPathSelector[SequencerSetSelector]. Each path and therefore the transition between different se-
quencer sets is based on a defined trigger and an aimed next sequencer set which is selectable by Sequencer←-
SetNext[SequencerSetSelector][SequencerPathSelector]. After the trigger occurs the settings of the next set
are active. The trigger is defined by the features SequencerTriggerSource[SequencerSetSelector][Sequencer←-
PathSelector] and SequencerTriggerActivation[SequencerSetSelector][SequencerPathSelector]. The functions
of these features are the same as TriggerSource and TriggerActivation. For a flexible sequencer implementation,
the SequencerPathSelector[SequencerSetSelector] should be part of the sequencer sets.

Description
SequencerMode sequencerMode Controls if the sequencer mech-
anism is active. Possible values
are:
• Off: Disables the sequencer.
• On: Enables the sequencer.
SequencerConfigurationMode sequencerConfigurationMode Controls if the sequencer config-
uration mode is active. Possible
values are:
• Off: Disables the sequencer
configuration mode.
• On: Enables the sequencer
configuration mode.
