Image Acquisition
This chapter gives detailed information about the controlling of the image acquisition. It
shows how the camera can be triggered or run in free-running mode, and how the frame rate
can be configured.
The structure offers a lot of flexibility in the configuration. It follows the GenI-
Cam naming convention. Typical camera configurations are included in the chap-
ter "Use Cases" in the Appendix C.
4.1 Overview
The overview shows the major camera elements which are involved in the image acquisition.
The section starts with a description of the vocabulary and terms, which are used to explain the
acquisition related features.
4.1.1 Vocabulary
An acquisition is composed of one or many frames. A frame is a single acquired image which
consists of an exposure time and an image read out. A burst of frame is defined as a capture of
a group of one or many frames within an acquisition. So an acquisition can be grouped in N
single frames or N burst of frames.
4.1.2 Structure
The camera contains a block that controls the image acquisition which contains the sub-blocks
for acquisition control, frame control and exposure control. Furthermore there are a controller
blocks of I/O signals, counters, timers and software interface. All of these elements can be
connected through an interconnection, which allows to control the image acquisition by digital
input signals, by counters, by timers and/or software access.

4 Image Acquisition
Acquisition Control The acquisition control block takes care of the acquisition function. The
camera can only capture frames, when the acquisition has been started and is active (see
Section 4.2 for more information).
Frame Control The frame control block takes care of the capturing of one or many frames and
burst of frames (see Section 4.3 for more information).
Exposure Control The exposure control block takes care of the exposure time of a frame (see
Section 4.4 for more information).
Counter The camera has four independent counters. They count events from a selectable
source (see Section 5.1 for more information about counter configuration and usage).
Timer The camera has four independent timers. A timer delay and duration are configurable
and the timers are triggered by a selectable source (see Section 5.2 for more information
about timer configuration and usage).
I/O Control The I/O control unit manages physical camera inputs and outputs and LED. A
switch matrix within this block allows connecting internal status signals to the output
lines or LED. Status signals can come from the acquisition, frame or exposure control
block, also from timer or counter, or even input lines can be routed to an output. The
input lines can be used to control the acquisition, frame and/or exposure, also to start a
timer or count events with a counter (see Chapter 6 for more information).
Software Signal Pulse and User Output The camera has user outputs, which can be set to 1 or
0 by software access, and a software signal pulse generator block (see Section 4.7). These
user outputs and signal pulses can be used to control camera functions by software
access, such like acquisition and frame capture or counter and timer.
Signal Routing All these elements are connected to each other by the signal routing block. The
following sections show which signals are available and how they can be used in the
others blocks.
4.1.3 Image Acquisition, Frame and Exposure Control Parameters
Mainly the following commands/settings are involved in order to control and configure the
camera acquisition and frame capturing:
• Acquisition Start and Stop Command
• Acquisition Mode (Single Frame, Multi Frame, Continuous Frame)
• Acquisition Frame Count
• Acquisition Frame Burst Count
• Acquisition Frame Rate
• Exposure Mode (Timed, Trigger Controlled)
• Exposure Time
This list shows only an overview of available parameters. The function and usage of them are
explained in the following chapters.
