ABSTRACT
Computational sensors (smart sensors, a vision chip in other words) are a very small integrated system, in which processing and sensing are unified on a single VLSI chip. It is designed for a specific targeted application. Research activities of computational sensors are described in this chapter. There have been quite a few proposals and implementations in computational sensors. First, their approaches are summarized from several points of view, such as advantages vs. disadvantages, neural vs. functional, architecture, analog vs. digital, local vs. global processing, imaging vs. processing, and new processing paradigms. Then, several examples are introduced, which are spatial processings, temporal processings, A/D conversions, and programmable computational sensors.
