Abstract
A high-fidelity video digitizer/processor extracts spatial and gray-scale information from high resolution dynamic video imagery. The 15-MHz bandwidth 60/s images (fields) are low pass filtered to minimize aliasing and digitized in real-time at 20 million samples pe second (MS/s), 9 bits/sample; sequential fields are transferred to memory, retrieved from memory after computer image processing, and reconstituted at up to 40 MS/s into 60 field/s video of 525, 875, or 1225 lines/frame (two interlaced fields). A/D and D/A converters are synchronized with memory by a high-speed interface, composed of a central data interchange (DI), and 8 radially connected I/O ports.
