Glossary

ADC

Analog to digital converter

Administrator

(Rights) administrator for PC systems at operating system level

ASCII

American standard code for information interchange

Baud

see baud rate

Baud rate

Unit: Baud, number of data units transferred in one second

BIOS

Basic input/output system, 'minimum' operating system for PC booting; allows,

 

among others, settings to be made on available communication (e.g. integral

 

FireWire™) interfaces

Bit

Smallest information unit in digital data processing, values '0' (low, L, off state)

 

and '1' (high, H, on state)

Byte

Combination of 8 bits to form an information unit, value range 28 (0...255)

CameraLink™

Parallel digital transmission standard

CD-ROM

Compact disc read-only memory, storage medium consisting of a metal-

 

coated plastic disk with an information storage layer

Chip set

Set of large-scale integrated circuits in personal computers performing special

 

functions, e.g. the provision of data communication interfaces

CMOS

Complementary metal oxide semiconductor, modern semiconductor

 

technology used e.g. in optical sensors

C mount

standardized mount for optical components, e.g. lenses

dB

see decibel

Decibel

logarithmic measure of a physical unit, e.g. the range of contrast K=20*log

 

(max. contrast/min. contrast) [contrast range in full frame]

DIN

Deutsche Industrie-Norm (German industrial standard)

D-SUB

Standardized connector format with trapezoidal connector screen and two or

 

three lines of male/female contacts for external PC ports, e.g. serial RS-232

 

interfaces

ESD

Electrostatic discharge, ESD caused by electrostatic charging must be

 

avoided when handling PC plug-in cards

EN

European standard

FireWire™

Serial digital transmission standard, also known as IEEE1394a or iLink™

 

(Apple trademark)

Firmware

Operating software of camera function units

fixed pattern noise

Abbr. FPN, here: static image noise on sensors caused during production by

 

random physical processes, results for example in an inhomogeneous grey of

 

a homogeneously illuminated area

fps

Frames per second, frame rate

FPGA

Field programmable gate array, large-scale integrated electronic module

 

comprising a large number of elementary logic elements which can be

 

programmed to carry out complex functions

framegrabber

Framegrabbing unit for electronic cameras, mostly in form of PCI plug-in

 

cards for the PC

Hz

Hertz, unit of frequency (1 MHz = 106 Hz)

Interrupt

(Purposeful) interruption, e.g. of data transmissions or program runs

IPC

see PC

Linux

Alternative PC operating system based on UNIX

LOGLUX®

Product name and acronym derived from 'logarithmic' and 'light' [Greek: Lux]

long

Here: data format comprising 4 bytes or 32 bits, value range: 232

LSB

Lowest significant bit of a larger information unit such as a byte

LUT

Look-up table, value assignment table, e.g. greyscale image data

macro

Function unit, e.g. of camera control commands

MCU

Microcontroller unit

MHz

see Hz

MSB

Highest significant bit of a larger information unit such as a byte

OHCI

Open host controller interface, standard interface for the unified connection of
