GenICam stands for GENeric programming Interface for CAMeras.
It's a generic way to access and modify device parameters with a
unified interface. A GenICam compliant device either directly provides
a GenICam compliant description file (in internal memory) or the
description file can be obtained from a local (hard disk etc.) or web
location. A GenICam description file is something like a machine
readable device manual. It provides a user readable name and value
range for parameters that are offered by the device for reading and/or
writing and instructions on what command must be send to a device when
the user modifies or reads a certain parameter from the device. These
description files are written in XML. An excerpt from such a file can
be seen in the figure below:

For further information on this topic please have a look at How to get access to a certain feature in an application that works with the GenICam
interface and for information on the difference between the GenICam interface layout
and the mvIMPACT Acquire interface please have a look at the chapter matching your
preferred programming language:

  • "About different interface layouts"
GenTL GenTL is the transport layer interface for
cameras, acquiring images from the camera, and moving them to the
user application.
Gigabit Ethernet (GigE) The term Gigabit Ethernet (defined by the
IEEE 802.3-2008 standard) represents various technologies for
transmitting Ethernet frames at a rate of a gigabit per second
(1,000,000,000 bits per second).
GigE Vision

GigE Vision is a network protocol designed for the
communication between an imaging device and an application. This protocol completely

  • device discovery
  • data transmission
    • image data
    • additional data
  • read/write of parameters.
    GigE Vision uses UDP for data transmission to reduce overhead introduced by TCP.
    UDP does not guarantee the order in which packets reach the client nor
    does it guarantee that packets arrive at the client at all. However,
    GigE Vision defines mechanisms that can detect lost packets.
    This allows capture driver manufacturers to implement algorithms
    that can reconstruct images and other data by requesting the device to
    resend lost data packets until the complete buffer has been assembled. For further information please have a look at
    The MATRIX VISION GigE Vision capture filter driver as well as the socket based
    acquisition driver and all MATRIX VISION GigE Vision compliant devices support
    resending thus lost data can be detected and in most cases reconstructed. This
    of course can not enhance the max. bandwidth of the transmission line thus if
    e.g. parts of the transmission line are overloaded for a longer period of time
    data will be lost anyway.
    Both capture drivers will allow to fine tune the resend algorithm used internally
    and both drivers will also provide information about the amount of data lost and
    the amount of data that was re-requested. This information/configuration will be
    part of the drivers SDK. More information about it can be found in the
    corresponding interface description.
On Windows 2000 the filter driver does not support the "Resend" mechanism.
High Dynamic Range (HDR) The HDR (High Dynamic Range) mode increases
the usable contrast range. This is achieved by dividing the integration
time in two or three phases. The exposure time proportion of the three
phases can be set independently. Furthermore, it can be set, how many
signal of each phase is charged.
IDE a software application that provides comprehensive facilities to
computer programmers for software development. An IDE normally
consists of a source code editor, a compiler and/or interpreter,
build automation tools, and (usually) a debugger.
mvIMPACT Acquire

This driver supplied with MATRIX VISION products represents
the port between the programmer and the hardware. The driver concept
of MATRIX VISION provides a standardized programming interface to all
image processing products made by
The advantage of this concept for the programmer
is that a developed application runs without the need for any major
modifications to the various image processing products made by MATRIX
VISION GmbH. You can also incorporate new driver versions, which are
available for download free of charge on our website:

The developer interface description of the mvIMPACT Acquire is called

  • mvIMPACT_Acquire_API_CPP_manual.chm
  • mvIMPACT_Acquire_API_C_manual.chm
  • mvIMPACT_Acquire_API_NET_manual.chm

and can be downloaded from our website.

NFS Network File System (NFS) is a network file system protocol,
allowing clients to access files over LAN. Given that you need a NFS
server are uncommon on Windows, this protocol best fits for Linux-Linux
Overlapped / pipelined transfer

By default, the steps exposure and readout out of an image sensor are done one after the other.

  • By design, CCD sensors support overlap capabilities also combined with trigger (see figure).
  • In contrast, so-called pipelined CMOS sensors only support the overlapped mode. Even less CMOS sensors support the overlapped mode combined with trigger.

Please check the sensor summary.

In overlapping mode, the exposure starts the exposure time earlier during readout.

In overlapped trigger mode, you have to keep in mind the following formula
 interval between two trigger events >= (readout time - exposure time)

software library from MARTIX VISION is mvIMPACT.

Shell In computing, a shell is a piece of software that provides an
interface for users. Command-line shells provide a command-line
interface (CLI) to the operating system. The primary purpose of
the shell is to invoke or "launch" another program; however, shells
frequently have additional capabilities such as viewing the
contents of directories.
USB3 Vision A closed source framework, defined and administered by the Automated Imaging Association (AIA), for transmitting video and related control data over USB 3. Sometimes U3V is used as an acronym.
Virtual Network Computing (VNC)

Virtual Network Computing (VNC) is a
graphical desktop sharing system that uses the RFB protocol
to remotely control another computer. Over a network, it
transmits the mouse and keyboard events from one computer
to another, relaying the graphical screen updates back in
the other direction.

To access the camera's desktop from a PC via VNC,

  • you have to know the IP address of the remote system.
  • Start a VNC viewer and
  • point it to the remote system.

You won't need a password. Of course, you won't get a very
fast live image display via the network with VNC but you
should be able to start wxPropView and capture images.
