A generic real-time video processing unit for low vision

Abstract We describe a generic real-time video processing system for applications in the field of electronic visual aids. A working system has been implemented using a specific hardware (FPGA device) to achieve real-time processing in low cost portable systems. The inclusion of a reconfigurable circuit FPGA allows real-time video processing, the setting control by the user, and personalisation for each individual person in a simple way, resulting in a unique platform to be included in static and portable CCTV systems or in video displays. Several processing algorithms applied to a video source, as digital zoom, edge enhancement or the augmented view scheme are implemented in this device.
