High Definition Stereo Image Processor

Design Note #111

High Definition Stereo Image Processor

Medical imaging for surgical procedures benefits from high definition imaging systems. Low latency high definition CMOS image sensors may be inserted into the body to view previously inaccessible regions of the human anatomy. Stereo imaging gives the surgeon an adjustable depth perspective in real time. High speed laser based optical links between camera and processing equipment achieve a high degree of reliability and patient safety.

Altera Cyclone and Stratix FPGAs

Altera FPGA technology together with OTEC’s Verilog Image Processing Chain achieves extremely low latency processed video. Image latency below single frame timing is achievable. OTEC’s Image processing IP includes:

• Bayer Color Conversion

• Low Latency Adjustable Zoom

• Gamma Image Correction

• LUT Color Replacement

• HD-SDI Image Generation

• Color Bar Testing

• Region of Interest Detection

• Overlay Image Processing

High Speed DDR3 Memory Subsystem

Dual high speed, 64 bit wide DDR3 memory banks permit the rapid processing of incoming and outgoing video data. 64 bit wide memory allows internal FPGA processes to run at comfortable data rates while maximizing overall data throughput.
