Complex Digital Functions
What do you get when you combine 3.1 million
pixelswithacrispdigitalouput?Micron'sMT9T031
CMOS image sensor, complete with electronic pan
andtiltcapabilities.At3.1megapixels,theMT9T031
provides a wide field of view (FOV) that can be
subwindowed, positioned, and sized to enable a
low-cost,high-performance,highlyreliablepan/tilt
camerawithnomovingparts.
With the subwindow sized to produce VGA video,
the camera focuses on 300,000 of the 3.1 million
pixelsatonetime,leavingtherestofthesceneto

High Resolution, High Speed
The MT9T031 showcases Micron's groundbreaking
DigitalClarity technology, which enables brilliant,
high-resolution color images that rival CCD-level
image quality (based on signal-to-noise ratio and
low-lightsensitivity)withoutCCD-levelpowercon-
sumption. The MT9T031 superbly captures single
frames as well as continuous video. What's more,
the sensor's high-speed readout and fast auto ex-
posure,autofocus,andviewfindermodeseliminate

Ease of Design.
Speed of Development.
WithfewerrequiredpartscomparedtoCCD-based
sensors, Micron's MT9T031 CMOS image sensor
simplifies camera design. Its on-chip analog-to-
digital conversion, clock generation, and other
sophisticated camera functions enable designers
to create smaller, higher-performance, lower-cost
applications within shorter product development
periods.
