AOI is means the a

user-defined area for
measurement application for saving system
images processing time.
Bit Depth -The number of bits used to
code a value (such as a pixel component)
into an integer value. This is directly
related to the number of levels that the
value might have, such as 256 with an
8-bit depth or 1,024 with a 10-bit depth.
CMOS (Complementary Metal-Oxide Semiconductor) – CMOS is a widely used type
of semiconductor. CMOS semiconductors use both
r than chips
so they tend to be extremely inexpensive
the trademark 'FireWire', in reference to it
NMOS (negative polarity) and PMOS (positive polarity)
circuits. Since only one of the circuit types is on at any
given time, CMOS chips require less powe
using just one type of transistor. CMOS traditionally
consumes little power and can be fabricated on just
n production line,
about any standard silico
compared to CCD sensors.
FireWire/1394 - The 1394 digital link
standard was conceived in 1986 by
technologists at Apple Computer, who chose
s
spee s of operation. In 1995, the IEEE d
(Institute of Electrical and Electronic Engineers) defined this standard is IEEE 1394.
There are two IEEE 1394 standards in current market; 1394a for data transmission rates
up to 400Mbps, and the other is IEEE 1394b; for data transmission rates up to 800Mbps.
