E
EEPROM
Electrically Erasable Programmable Read-Only
Memory. An on-board non-volatile memory chip.
Element
The basic unit of data encoding in a 1D or 2D
symbol. A single bar, space, cell, dot.
Exposure Time
For digital cameras based on image sensors
equipped with an electronic shutter, it defines the
time during which the image will be exposed to the
sensor to be acquired.
F
Flash
Non-volatile memory for storing application and
configuration files.
H
Host
A computer that serves other terminals in a network,
providing services such as network control, database
access, special programs, supervisory programs, or
programming languages.
I
Image Processing
Any form of information processing for which the
input is an image and the output is, for instance, a
set of features of the image.
Image Resolution
The number of rows and columns of pixels in an
image. The total number of pixels of an image
sensor.
Image Sensor
Device converting a visual image to an electric signal.
It is usually an array of CCD (Charge Coupled
Devices) or CMOS (Complementary Metal Oxide
Semiconductor) pixel sensors.
IEC
(International Electrotechnical Commission): Global
organization that publishes international standards
for electrical, electronic, and other technologies.
IP Address
The terminal’s network address. Networks use IP
addresses to determine where to send data that is
being transmitted over a network. An IP address is a
32-bit number referred to as a series of 8-bit
numbers in decimal dot notation (for example,
130.24.34.03). The highest 8-bit number you can use
is 254.
ISO
(International Organization for Standardization): A
network of the national standards institutes of several
countries producing world-wide industrial and
commercial standards.
L
LED (Light Emitting Diode)
A low power electronic light source commonly used
as an indicator light. It uses less power than an
incandescent light bulb but more than a Liquid
Crystal Display (LCD).
LED Illuminator
LED technology used as an extended lighting source
in which extra optics added to the chip allow it to
emit a complex radiated light pattern.
M
Matrix Symbologies (2D Codes)
An arrangement of regular polygon shaped cells
where the center-to-center distance of adjacent
elements is uniform. Matrix symbols may include
recognition patterns which do not follow the same
rules as the other elements within the symbol.
Multi-row (or Stacked) Symbologies
Symbologies where a long symbol is broken into
sections and stacked one upon another similar to
sentences in a paragraph.
