Bringing High-Performance Video to
Low-Cost Home Security Systems
Until the introduction of the MT9D131 security cam-
era, designers were forced to sacrifice performance
for cost. With Micron’s 2-megapixel camera system-
on-a-chip, they have an image sensor to design in to
consumer security applications. It outputs full-color
digital video at greater-than-VGA resolutions and
makes scenes and stills clear enough to enable e-mail
or remote viewing.
Unparalleled CMOS Image Quality
Micron’s exclusive DigitalClarity technology dramati-
cally reduces noise levels in our CMOS sensors. While
some security cameras generate shots that look like
abstract paintings, your MT9D131-equipped camera
will deliver sharp, crystal-clear images. Our sensor

Sophisticated On-Board Image
Processing
Our new CMOS image sensor is a complete, inno-
vative camera system-on-a-chip (SOC). With the
MT9D131, designers can simply plug ‘n’ play—for
basic operation, it requires only a power supply,
lens, and clock source. Its on-chip image flow proces-
sor performs a host of image correcting and enhanc-
ing functions you’d normally need another part for,
such as color recovery and correction; sharpening;
gamma correction; and automatic black level offset
correction, exposure, white balance, lens shading,
and flicker avoidance.

mote viewing. The entire field of view of the sen-
sor can be scanned to display any one portion at a
time—without using a motor or any moving parts.
Additionally, because it is fully interpolated, the
zoom moves smoothly instead of jumping from 2X
to 4X as most digital zoom functions do. Until now,
this type of functionality has been out of the reach
of regular home owners.
A Complete System
The camera system features a microcontroller (MCU)
and a sophisticated image flow processor (IFP) with
a real-time JPEG encoder. The microcontroller man-
