An adaptable foveating vision chip

In this work we present an adaptable foveating vision biological eye has exceptionally good optomechanics. This chip. This chip has no physical foveation; all its pixels are in the enables the eye to be moved round the visual field at high speeds. same uniform pattern. However with a given input signal it is In contrast, even with modem MEMS technologies, it is possible to define areas of the chip which act as a fovea, returning challenging to position silicon-based cameras with as many high spatial resolution. The surrounding peripheral vision acts to degrees of freedom at such high speed and accuracy, in addition return lower spatial resolution but much higher temporal to being compact. In silicon however, it is possible to resolution. Our chip is therefore able to achieve full spatial electronically define and reposition the fovea, something difficult resolution via scanning of the fovea across the visual field. This in biology and not seen in nature. Thus, the authors of this paper...
