Made for Home and Office Networks
Micron Technology’s MT9M131 is an SXGA-format,
single-chip camera with a 1/3-inch CMOS active-
pixel digital image sensor. With the MT9M131
designed in, users can get an affordable
security system that produces high-quality digital
video output. Its progressive-scan images are ideal
for porting to compression and network interface
chips. Data streaming across a network is kept to a
minimum, so the network doesn’t get bogged down
or overloaded.

Featuring Six 8-Bit Formats
The MT9M131 can be programmed to output
progressive-scan images at up to 30 (fps) in preview/
power-saving mode and 15 fps in full-resolution
(SXGA) mode. In either mode, the image data can
be output in any one of six 8-bit formats.
Low Noise, Low Power,
Better Low-Light Performance
Developed by a world-renowned group of imaging
experts, the MT9M131 provides superior low-light
performance, achieving CCD-quality sensitivity levels.
Equipped with Micron’s progressive readout, low-
noise DigitalClarity technology, the high-perfor-
mance MT9M131 delivers brilliant color images
even under some of the poorest lighting conditions,
making it ideal for high-resolution network security
cameras.
Sophisticated On-Board Image Processing
For basic operation, the innovative camera system-
on-a-chip (SOC) requires only a power supply, lens,
and clock source. With the MT9M131, designers
can simply plug and play. Its on-chip image flow
processor performs a host of image correcting and
enhancing functions you’d normally need another
part for, such as color recovery and correction; sharp-
ening; gamma correction; and auto black level offset
correction, exposure, white balance, lens shading,
flicker avoidance, and on-the-fly defect correction
directly on the chip itself, minimizing device form
factor as well as needed board space. And because
it requires fewer parts, the MT9M131 simplifies
design compared to CCDs and enables a much faster
time-to-market.
