P2X-SERIES™
DEPTH OF FIELD
The difference between the minimum and the maximum distance of the object in the
field of view that appears to be in focus.
DIFFUSED ILLUMINATION
Distributed soft lighting from a wide variety of angles used to eliminate shadows and
direct reflection effects from highly reflective surfaces.
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.
FLASH
Non-volatile memory for storing application and configuration files.
HOST
A computer that serves other terminals in a network, providing services such as net-
work control, database access, special programs, supervisory programs, or program-
ming languages.
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.
INTERNAL ILLUMINATOR
The strobe illuminator that is an integral part of the lens cover for the P2x-Series™.
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 (e.g., 130.24.34.03). The highest
8-bit number you can use is 254.
