Silicon Imaging MegaCamera™ SI-3170
Silicon Imaging MegaCamera
 SI-3170
3.2 Megapixel (2048 x 1536), 12-Bit Resolution
30 FPS High Definition Digital Camera
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 2048 x 1536 resolution. Its ½” imaging format is
ideal for use with standard lenses, microscopes and intensifiers. The entire
micro-head package is 45 x 52 x 50mm and is small enough to be
embedded in a biophotonic instrument or placed on a robot for machine
vision inspection.
30FPS High-Definition 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 30fps digital camera system.
12-Bit Pixel Clock Sampling – Sub-Pixel Accuracy
The MegaCamera uses dual 12-Bit digitizers to sample 2 output taps,
each at 50MHz to achieve 100Mpixel/sec or 30 Frames/sec data
throughput at its full resolution of 3.2Megapixels. Converting the pixel data
directly to digital at the sensor head eliminates pixel-sampling jitter and
enables accurate sub-pixel metrology, image analysis and improved live
video reconstruction. Either 12bit or 8-bit data can be selected for highspeed transfer into PC memory.
500FPS High Frame Rate Windowing & Digital Pan/Tilt/Zoom
A reduced size region of interest (windowing) enables readout rates in
excess of 500 frames per second making it ideal for motion analysis, autofocus or object tracking. This feature can also be used for electronic pan, tilt
and 16x digital zoom. For HDTV applications, the aspect ratio can be
switched from the traditional 4:3 to 16:9 with 1920x1080 resolution.
Serial Capture & Control
The SI3170 is fully programmable through its serial port. These functions
include sampling clock speed, region-of interest window, global gain, RGB
gain, exposure, frame-rate and triggering modes. The camera can operate
in live continuous or in single-shot capture. The capture event can be
started from software command or hardware trigger.
All-Digital Interface - CameraLink
Traditionally, 12 bit per pixel resolution and multi-tap cameras require a
large number of parallel digital signals, which becomes cumbersome to
cable and physically large to connect. The SI3170 utilizes high Speed
digital multiplexers to serialize the image data and transmit 1.2Gb/sec of
data, clock and triggers over just a few twisted pairs, thereby minimizing the
cable size and increased flexibility. An industry standard forum of Camera
and Frame Grabber manufacturers has adopted this method, called
CameraLink, for low cost high bandwidth PC connectivity and cabling.
Silicon Imaging specialize in the design, manufacturing and marketing of
high-definition digital cameras and image processing solutions for the
machine vision, medical, scientific instrumentation, entertainment and
surveillance markets. Silicon's focus has been to exploit the recent
advancements in CMOS imagers and digital processors to develop a new
generation of high definition products, which can outperform traditional
video camera and processing systems at a lower cost.
