Pixim D1000 Video Imaging System
for CCTV Cameras
The Pixim D1000 is a highly integrated two chip set utilizing Pixim's innovative new
Digital Pixel System
TM
(DPS) technology that provides the image sensor and the
necessary intelligence to develop high quality, cost-effective color CCTV cameras. The
D1000 is designed to deliver superior quality video, providing up to 95 dB dynamic
range in normal operation while providing excellent resolution, sensitivity and color
fidelity. The D1000 includes configurable software which allows camera manufacturers
to get to market quickly and offer a number of camera products from the same base
hardware design, including an option to select PAL / NTSC operation via a jumper or
switch. Composite and S-Video outputs are available.
The chip set is manufactured in a high volume commercial 0.18 micron CMOS process,
utilizing 1.8V operation for low power dissipation.

About DPS
Pixim's patented Digital Pixel System
TM
(DPS)
technology marks a fundamental breakthrough in
imaging technology. Building upon technology
developed at Stanford University in the 1990s,
Pixim has created an image capture and
processing system that provides high-quality
pictures with enhanced dynamic range. Greater
dynamic range significantly improves image
quality in scenes consisting of both bright and
dark areas.
The core invention in DPS is the inclusion of an
analog-to-digital converter (ADC) within each pixel
of the image sensor. The ADC translates the light
signal into a digital value at the immediate point of
capture, thus minimizing signal degradation and
cross-talk in the array and allowing for greater
noise reduction methods. Once the data is
captured in a digital format, a variety of digital
signal processing techniques are used for optimal
image reproduction.
As imaging technology continues to migrate
toward totally digital systems, Pixim's Digital Pixel
System technology will provide the foundation for
image capture and image processing for the
highest quality video and still cameras.
