Complex Digital Functions
What do you get when you combine 5 million pixels
with a crisp digital ouput? Micron’s MT9P031 CMOS
image sensor, complete with electronic pan and tilt
capabilities. At 5 megapixels, the MT9P031 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 5 million
pixels at one time, leaving the rest of the scene to
be accessed through the pan and tilt functions. The
MT9P031 supports both 2X and 3X reductions of the
output resolution and enables independent binning
of rows and columns—which means precise manipulation of images and a wider FOV image is possible
without having to output all of the pixels that the
scene comprises. Additionally, the MT9P031 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 MT9P031 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
consumption. The MT9P031 superbly captures single
frames as well as continuous video. What’s more,
the sensor’s high-speed readout and viewfinder
modes eliminate two common commercial security
camera problems: shot-to-shot delay and video-tostill lag—the delay between when someone presses
the camera’s button and when the picture is actually
taken.
Ease of Design, Speed of Development
With fewer required parts compared to CCD-based
sensors, Micron’s MT9P031 CMOS image sensor
simplifies camera design. Its on-chip analog-todigital conversion, clock generation, and other
sophisticated camera functions enable designers
to create smaller, higher-performance, lower-cost
applications within shorter product development
periods.
