FPN
Fixed Pattern Noise (equivalent to DSNU). FPN is the peak to peak difference between the
minimum and maximum measured values for all active valid pixels sensor in darkness. Fixed
Pattern Noise does not include a Random Noise component.
Frame
One complete image data set or its equivalent storage space.
Frame buffer
An area of memory used to hold a frame of image data. A frame buffer may exist on the
acquisition hardware or be allocated by the acquisition hardware device driver in host system
memory.
GigE Vision specification
Specification of the Automated Imaging Association (AIA, www.machinevisiononline.org).
Defines the communication interface protocol used by any GigE Vision device.
GenICam specification
Specification of the European Machine Vision Association (EMVA, www.emva.org).
Defines the capabilities of any GigE Vision device.
Grab
Acquiring an image frame.
Grayscale
In image processing, the range of available brightness levels, displayed in shades of gray. In
an 8-bit system, the gray scale contains values from 0 to 255.
GVCP – GigE Vision Control Protocol
One of the core protocols of the GigE Vision specification used to control camera. GVCP
uses UDP port 3956 on the camera.
GVSP – GigE Vision Stream Protocol
One of the core protocols of the GigE Vision specification used to stream images.
Host
Refers to the computer system that supports the installed frame grabber.
IP – Internet Protocol
The Internet Protocol is the method by which data is sent from one computer to another on a
network or across the Internet. Each device must have an IP address to identify that device on
the network or on the Internet.
LLA
Link-Local Address is a protocol providing a scheme for devices to automatically assign
themselves an IP address and check for IP conflict. Used in unmanaged networks.
