2 Silicon Imaging MegaCamera 3.2 Megapixel Micro-HD (2048 x 1536) 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. The entire micro-head package is 45 x 52 x 50mm and is small enough to be embedded in a biophotonic instruments 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 No Jitter 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 high-speed transfer into PC memory. 500FPS High Frame Rate Windowing A futher reduced size ROI enables readout rates in excess of 1000 frames per second, ideal for motion analysis or object tracking. 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. 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.

3 CMOS Camera Block Diagram Acquisition PCB OEM Version 44 x 33 x 14mm - 2PCB Actual size LIVE VIDEO DISPLAY Image display is provided by the host computer's video graphics adapter (VGA) and monitor(s) or flat panel(s). Display resolution is a function of the capabilities of these devices. Some Super VGA (SVGA) monitors can display the full resolution of the camera image. A software look-up-table feature allows display of 8 bits from the 12 bit gray level image. COLOR BAYER CONVERSION & CORRECTION Bayer color Image data from the SI-3170RGB is converted to 24Bit RGB using the most advanced signal color conversion algorithm available. AWB Automatic White Balance functions are implemented to match the true world color to the calculated and displayed values. These functions are also available in the Imaging Library (S-LIB) for OEM applications. SOFTWARE A free ready-to-run interactive capture program (GRAB) that features camera control screens, line and column pixel plots, image sequence capture, and image sequence display. Images can be saved to disk for processing by other programs. ANALYZE is a ready-to-run interactive image processing and analysis program for qualitative and quantitative image operations. A few mouse clicks select FFTs, histograms, morphology, measurements, edge detection, correlations, 3D plots, arithmetic operations, and many other functions. The tools provide analysis of the SI-3170 images using 12 bits of grey level per pixel. GRAB can control up to 8 Frame Grabber boards in a single computer IMAGE PROCESSING LIBRARY An extensive programming library is available which includes sample code for image processing and allows application-specific code to be added to the large selection of functions already developed. No royalties are required for software developed using our libraries. SOLUTIONS and SUPPORT The Silicon Imaging team has provided vision solutions and support for OEM machine vision manufacturers, camera manufacturers, radiologists, astronomers, biologists, and engineers for 15 years.

4 SPECIFICAT IONS FG-3170 PCI-Bus Frame Grabber CameraLink Interface Camera Link is a new digital transmission method designed by imaging component manufacturers as an easy and standard way to connect digital cameras to frame grabbers. The Camera Link specification includes greater than 1.2Gb/sec data transmission as well as camera control and asynchronous serial communications all on a single cable with high-density 26pin connector. Only two connections are required to quickly interface your digital camera to a multitude of frame grabbers. Silicon Imaging has provided the option to further simplify cabling by allowing camera power (+5VDC) directly thru the CameraLink cable using up to 3 pairs of wires in the standard cable. As a standard that has been defined by industry members, Camera Link provides the following benefits: Features 32 bits, 33 MHz PCI slot Volts inches long by 4.20 inches high (short slot) CameraLink MDR-26 pin Connection Camera Power at +5VDC, optional Standard Interface: Every Camera Link product usea the same cable and signaling. Cameras and frame grabbers can easily be interchanged using the same cable. Software Requirements Requires Windows 16/24/32 bit RGB SVGA compatible display system. Display resolution as per installed VGA device driver. Direct Draw with hardware overlay recommended. Motherboard Requires a PCI motherboard capable of sustained transfer rates of at least 100 MB per second for full resolution image capture to motherboard DRAM. Advanced Graphics Port (AGP) PCI motherboard and AGP VGA is recommended. CameraLink Cable Diagram Simple Connection: Only two connections will be required to interface a camera and frame grabber: Power and Camera Link. Lower Cost: Because Camera Link is an industry-wide standard, consumers will be able to take advantage of lower cable prices. Smaller connectors & cables: The technology used in Camera Link reduces the number of wires required to transmit data over traditional LVDS or RS-422 parallel interfaces, allowing for smaller cables. Smaller cables are more robust and less prone to breakage. Higher data rates: The technology used in Camera Link has a maximum data rate of 2.3GB/s, for use in the most demanding high definition, high frame rate and line scan.
