1.3 Megapixel, 12-Bit Sampling

Full-Frame Shutter Digital Camera

Silicon Imaging Inc.

Silicon Imaging is proud to continue its innovation in ultra-high speed machine vision camera. Driven by the growing demand for consumer Digital Still Cameras, CMOS sensors are continuing to break technical barriers and 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 very compact, low-power, ultra high speed Megapixel digital camera system.

1280 x 1024 Megapixel Imaging - Ultra Speed

The SI-1280F is the worlds first 1.3 Million pixel Full-Frame Shutter, all-digital CMOS camera capable of running at video rates of 40 frames/second at its full 1280 x 1024 resolution and over 500 frames/per second at 320 x 240 resolution. The entire package is only 45 x 52 x 50mm and is small enough to placed on a robot for semiconductor machine vision inspection, embedded into a portable medical instrumentation for cell biology or placed in an aerial drones for remote surveillance.

12-Bit Pixel Clock Sampling – Sub-Pixel Accuracy

The MegaCameraä uses 12-Bit digitizers to sample the pixel data at up to 60MHz to achieve 40 Frames/sec data throughput at its full Megapixel resolution. 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.

Full-Frame Triggered Shutter – Stop the Motion

Most common CMOS sensors only have a “Rolling Shutter” to control the exposure time for each line in the image. This method can produce unwanted motion tilts or jagged edges, as each row ends integration after the previous one above it. The SI-1280F provides a Full-Frame triggered shutter, which completely stops any motion artifacts by exposing all pixels simultaneously and holding the exposed value until it is progressively readout.

Dual Slope Exposure - “Super-Dynamic Range”

The SI-1280F can be used in a dual slope bi-linear mode, extending the useful dynamic range in scenes where detail in bright areas are to be preserved at the same time as maintaining details in darker regions. In normal linear response, a camera requires a short exposure to keep the bright areas from saturation. However, the darker regions of the image would not have enough time to integrate charge. If the exposure is set longer the detail in the dark areas will become visible by the brighter areas will become saturated. The dual-slope operation combines the transfer of nominal integration time (steep slope, high sensitivity) with the transfer curve obtained from a short electronic shutter (shorter exposure time, lower sensitivity), into a single exposing operation.

500 Frames per Second - Windowing & Subsampling

Ideal for object tracking and high-speed Motion analysis, the SI-1280 is capable of generating imagery at over 500 frames per second by reducing the size of the readout image (ex. 100x100). This windowed Region-of–Interest (ROI) can be moved dynamically, creating an entirely electronic pan/tilt/zoom function within the camera field-of-view.

USB2.0 Bus-Powered – 40MB/sec Transfers

For low-cost and portable connectivity, with data transfer rates up to 40MB/sec, the SI-1300U provide convenient capture using the High-Speed 480Mb/sec USB 2.0 interface. It is a bus-powered unit, consuming less than 500mA at 5VDC and will operate without any external power supply. The precision-machined C-mount housing includes an integrated tethered USB cable and optional 3-pin trigger/strobe connection. For OEM board level configurations, two General Purpose Outputs are accessible; Pull-Up and pull-down driven transistors to be used to control light sources and switches.
