Paper Abstract

We report on processing techniques to effectively control the data bandwidth in larger format Focal Plane Array (FPA) sensors. Bandwidth reduction techniques are possible using image processing functions near or on the FPA. We have developed image processing techniques that give a controlled reduction in the data rate via simple circuit that estimate Activity on the FPA image plane. By filtering on the FPA and sensing pixel signal changes, this allows only transmitting pixel data that are have less interest, and more efficiently manages data flow from the FPA. We describe and demonstrate results of "Activity Sensing" processing near the FPA. The associated computational efficiency with this type of on FPA processing allows data rate reduction from > 20 Mbytes/sec to under 10Kbytes/sec . We report on the continuing development and performance benefits expected from an Activity Sensing algorithm using recorded infrared (IR) data from a large format 1024 x 1024 variable acuity1 FPA.
