A foveated vision of a human visual processing system is known to reduce the amount of information passed to subsequent processing layers significantly and lends itself to fast image processing and pattern recognition tasks. In order to realize such a vision chip based on the foveated vision processing system, we propose two concepts: the receptive field and the refractory period. Our vision chip can focus the fovea on a target electrically using these concepts.
