Complex Digital Functions
What do you get when you combine 3.1 million
pixels with a crisp digital ouput? Micron’s MT9T031
CMOS image sensor, complete with electronic pan
and tilt capabilities. At 3.1 megapixels, the MT9T031
provides a wide field of view (FOV) that can be
subwindowed, positioned, and sized to enable a
low-cost, high- performance, highly reliable pan/tilt
camera with no moving parts.
With the subwindow sized to produce VGA video,
the camera focuses on 300,000 of the 3.1 million
pixels at one time, leaving the rest of the scene to
be accessed through the pan and tilt functions. The
MT9T031 supports both 2X and 3X reductions of the
output resolution and enables independent binning
of rows and columns—which means precise manip-
ulation of images and a wider FOV image is possible
without having to output all of the pixels that the
scene comprises. Additionally, the MT9T031 enables
an electronic zoom function by ending the binning
and selecting a subwindow frame or by reading out
all of the pixels.
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-light sensitivity) without CCD-level power con-
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, auto focus, and viewfinder modes eliminate
two common commercial security camera problems:
shot-to-shot delay and video-to-still lag—the delay
between when someone presses the camera’s but-
ton and when the picture is actually taken.
Ease of Design.
Speed of Development.
With fewer required parts compared to CCD-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.
