The BLINC digital camera, a prototype developed by the Sarnoff Corporation
claims a massive 17 stops of dynamic range. This tiny digital camera uses
a CMOS sensor which captures VGA images. "While Kodak and others
were emphasizing image sharpness in their CMOS chips, Sarnoff's researchers
were more concerned with its dynamic or exposure range". This particular
digital camera isn't aimed at digital still acquisition or to produce
images of that quality it is definetly noteworthy for the potential it
may offer future digital still cameras.
BLINC Miniature Smart Digital Camera Now Available for Delivery
in Prototype and Small Quantities

CMOS APS Sensor Captures Details across Highlights and Shadows; Fast
Response, Low Power Draw for Still and Video Images
Princeton, NJ (April 17, 2001)Sarnoff Corporation, a pioneer in
the development of video cameras and imagers, today announced the availability
of its BLINC smart digital camera in prototype and small quantities
for use in surveillance, automotive, and machine vision applications.
The announcement was made at a demonstration of the camera at the SPIE
Aerosense conference in Orlando, Fl.
BLINC delivers over 100X the dynamic range of typical cameras, capturing
all details in scenes even when they include simultaneous sunlight and
deep shadow. It goes from power-down to image capture in under 1/10th
second, provides both still image and 30 frame per second video capture,
and offers digital and analog output at VGA resolution (640 X 480). The
complete camera assembly is only 30mm (1.2 in) square by 2.5mm (1.0 in)
deep
"Were pleased to offer this advanced camera in prototype and
small quantities, from 10 to 100 units or more, to those who need its
special capabilities. Our focus, however, is developing the high-volume
applications of the future," said Niel McCaffrey, Sarnoffs
Head of Advanced Imaging.
"BLINC has the proven ability to acquire excellent video with full
details in every frame even when scene lighting rapidly varies over a
range of 17 photographic stops. No other video camera can do that. BLINCs
wide dynamic range and fast response make it ideal for automotive and
surveillance applications."
The BLINC assembly is built around Sarnoffs proprietary CMOS Active
Pixel Sensor (APS) technology. Automatic contrast detail enhancement is
performed with an on-board real-time 16-bit DSP. The camera operates on
a single 3.6 volt power supply, requiring less than 90 mJ to capture a
frame.

BLINCs response speed of 1/10th of a second allows it to remain
in standby mode at zero power until just before exposure, further reducing
power requirements. Other cameras require as much as 2 seconds to set
exposure and capture an image. The camera offers a 110 dB dynamic range,
resulting in natural-looking electronic images that closely approximate
photographic film.
