The Pixim D2000 Video Imaging System is a highly integrated two chip set utilizing
Pixim's innovative new Digital Pixel System
effective color CCTV cameras. The D2000 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 D2000 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. Simultaneous analog (composite, S-video, or
component) and digital outputs are available.
For advanced applications that utilize additional processing or remote access, the D2000
offers an interface to an external processor. The chip set is manufactured in a high
volume commercial 0.18 micron CMOS process, utilizing 1.8V operation for low power
dissipation.

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.
