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 2

8

(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 = 10

6

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: 2

32

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
