Silicon
Imaging Inc.
Silicon Imaging
has
introduced the world first 3.2 Million pixel High Definition CMOS
all-digital camera capable of running at video rates of 30 frames/second
at its full 2056 x 1560 resolution.
The entire micro-head package is 48 x 42 x 35mm and is small
enough to be hand held for medical video
instruments or placed on a robot for machine vision inspection.
30FPS
3.2MP CMOS Technology breakthrough
CMOS
imagers are breaking technical barriers in noise, sensitivity and
dynamic range. Driven by
the growing demand for consumer Digital Still Cameras, CMOS sensors have
been developed which surpass the performance characteristics of CCD’s
in many photonic, imaging and consumer applications.
By utilizing a single highly integrated CMOS device, which
incorporates Megapixel sensing areas, timing generation, signal
processing and high bandwidth outputs, Silicon Imaging has developed a
compact high definition digital camera system.
12-Bit
Pixel Clock Sampling – No Jitter
The
SI-3170 MegaCamera uses 12-Bit digitizers to sample 2 output taps,
each at 50MHz to achieve a 100Mpixel/sec or 30 Frames/sec data
throughput and uses the 10 most significant bits for further processing.
Converting the pixel data directly to digital at the CMOS sensor
head eliminates pixel-sampling jitter and enables accurate sub-pixel
metrology, image analysis and improved live video reconstruction.
16:9
HDTV Aspect Ratio & High Frame Rates
For HDTV applications,
the aspect ratio can be switched from the traditional 4:3 to 16:9 by
utilizing a region-of-interest (ROI) readout.
A reduced size ROI enables readout rates in excess of 1000 frames
per second, ideal for motion analysis or object tracking.
A sub-sampled mode outputs a 640 x 480 pixel image representing
the entire image on the sensor.
All-Digital
Interface - Camera Linkä
For 12 bit per pixel resolution and multi-tap systems the number of
parallel digital signals becomes cumbersome to cable and physically
large to connect. Therefore,
high Speed digital multiplexers are used to serialize the image data and
transmit the 1.2Gb/sec data, clock and triggers over just a few twisted
pairs, thereby minimizing the cable size and increased flexibility.
An industry standard forum has adopted this method, called Camera
Linkä,
for camera and Frame
Grabber connectivity and low cost cabling.
High Speed
Transfer to PCI Bus
Silicon Imaging provides a high speed PCI Frame Grabber to receive
the 12 bit per pixel image data from the camera.
As a PCI bus master, the frame grabber can transfer image data to the host
computer's memory or a PCI bus target at rates up to 132 megabytes per
second. Imaging
applications which were once restricted to custom image processing
hardware, or limited by expensive image memory, can now be performed by
the SI-3170 Camera, frame grabber, imaging software, and a Pentium
computer.
