Some controls may not be supported by all camera models.
Trigger signal flow
Figure 80
shows an ideal diagram for the trigger signal flow for Alvium CSI-2 cameras. The external signal
can be a physical source, such as light barrier as hardware trigger or a software trigger. This external signal
starts the exposure of a frame. The end of exposure starts the readout. High levels show the active state of
a signal. The different
signals display the workflow
, not user controls.
