4.1 Overview
4.1.4 Image Acquisition, Frame and Exposure Trigger
The camera can run in "free-running" mode, which means that it captures images
automatically in full frame rate once the acquisition has been started. However the acquisition
and image capturing can be controlled by triggers. For this purposes, there are seven triggers
available:
• Acquisition Start Trigger
• Acquisition End Trigger
• Frame Start Trigger
• Frame Burst Start Trigger
• Frame Burst End Trigger
• Exposure Start Trigger
• Exposure End Trigger
The source of these trigger can be set for every trigger individually; it can come from an
external line, an internally generated pulse from the counters, the timers, the action signals or
from a pulse generated by a software command. Each of these triggers can be switched on or
off individually. The camera generates the triggers pulses internally, which are switched off.
The following sections (Acquisition, Frame & Exposure Control) show the usage of these
triggers.
Each trigger has its own source signal processing path. Section 4.6 gives more information
about the configuration.
4.1.5 Image Acquisition, Frame and Exposure Status
The following list shows the acquisition, frame and exposure related status signals:
• Acquisition Trigger Wait
• Acquisition Active
• Frame Trigger Wait
• Frame Active
• Exposure Active
These status signals are used within the camera to control the camera timing. The current state
of these signals can be read out by software. Furthermore it can be connected to an output
line or LED through the I/O control block (see Chapter 6), which allows tracking the status from
an external device. The timing of these signals are explained in the following sections.
