Glossary of Terms
Examples: 640 x 480 (VGA); 854 x 480 (WVGA); 1280 x 1024 (SXGA); 2048 x 1536
(QXGA).
Image Sensor
— A device that converts a visual image to an electrical signal; a
CCD
or
CMOS
array.
Initialize
— Implement serial configuration commands into the imager’s active memory.
Input
— A channel or communications line. Decoded data or a discrete signal that is
received by a device.
Integration
— Exposure of pixels on a
CMOS
sensor.
Ladder Orientation
— A linear symbol orientation in which the bars are parallel to the
symbol’s direction of travel.
Light-Emitting Diode (LED)
— A semiconductor device that emits light when conducting
current.
Lens
— A transparent piece of material with curved surfaces which either converge or
diverge light rays.
Machine Vision
— The automatic acquisition and analysis of images to obtain desired
data for controlling a specific activity.
Multidrop
— A communications protocol for networking two or more imagers or other
devices with a concentrator (or controller) and characterized by the use of individual
device addresses and the RS-485 standard.
Noise
— The same as static in a phone line or “snow” in a television picture, noise is any
unwanted electrical signal that interferes with the image being read and transferred by the
imager.
Normally Closed
— A discrete output state that is only active when open.
Normally Open
— A discrete output state that is only active when closed.
Object Plane
— An imaginary plane in the field of view, focused by an imager’s optical
system at the corresponding image plane on the sensor.
Output
— A channel or communications line. Data or discrete signals that are transmitted
or displayed by a device.
Parity
— An error detection routine in which one data bit in each character is set to
1
or
0
so that the total number of
1
bits in the data field is even or odd.
Picket Fence Orientation
— A linear symbol orientation in which the bars are perpendicular
to the symbol’s direction of travel.
Pitch
— Rotation of a linear or 2D symbol around an axis parallel to the symbol length on
the
Substrate
.
Pixel
— An individual element in a digitized image array; “picture element”.
Port
— Logical circuit for data entry and exit. (One or more ports may be included within a
single connector.)
Processing Time
— The time used by a vision system to receive, analyze and interpret
image information. Often expressed in “parts per minute”.
Programmable Logic Controller (PLC)
— An electronic device used in industrial automation
environments such as factory assembly lines and automotive manufacturing facilities.
