Abstract
With the shift of the information processing architecture from sequential processing to parallel and distributed processing has come a great change in the role of the sensor technology, with the integration of the electronic circuit as the background. In other words, the sensor is no longer considered simply as a signal-transforming device but rather as an information processing module . This paper discusses the processing architecture for sensing in terms of the parallel processing. Some examples of the parallel processing architectures for the sensor information is described from such new viewpoints as massively parallel processing vision, optical neurocomputing, active sensing, and sensor fusion.
