Gigabit Ethernet Gigabit Ethernet is an industry standard interface used for high-speed com-
puter networks that is now being adapted as a camera interface. This gen-
eralized networking interface is being adapted for use as a standard
interface for high-performance machine vision cameras that is called GigE
Vision.
GigE Vision GigE Vision is a new interface standard, published by the AIA, for high-per-
formance machine vision cameras. GigE (Gigabit Ethernet), on the other
hand, is simply the network structure on which GiGE Vision is built. The
GigE Vision standard includes both a hardware interface standard (Gigabit
Ethernet), communications protocols, and standardized camera control
registers. The camera control registers are based on a command structure
called GenICam. GenICam seeks to establish a common software interface
so that third party software can communicate with cameras from various
manufacturers without customization. GenICam is incorporated as part of
the GigE Vision standard. GigE Vision is analogous to FireWire's DCAM, or
IIDC interface standard and has great value for reducing camera system
integration costs and for improving ease of use.
Global pipelined
shutter A global pipelined shutter assures that the integration for all pixels starts
and stops at the same moment in time. The integration of the next image
is possible during the readout of the previously captured image.
Global shutter All pixels are exposed to the light at the same moment and for the same
time span.

High dynamic range In the high dynamic range mode various nonlinearity points, the so-called
knee-points (and integration time as a second parameter) can be freely
adjusted, leading to increased dynamic range. This enables the high
dynamic range of the sensor to be compressed into 8 bit, preserving inter-
esting details of the image. This mode is also known as multiple slope.
Horizontal binning In horizontal binning adjacent horizontal pixels in a line are combined in
pairs.
This means that in horizontal binning the light sensitivity of the camera is
also increased by a factor of two (6 dB). Signal-to-noise separation
improves by approx. 3 dB. Horizontal resolution is lowered, depending on
the model.
