1. An apparatus for providing image sensing, the apparatus comprising: a pixel array having a plurality of pixels arranged in two dimensions, wherein: input sensed by each pixel of the plurality of pixels results in a value associated with each pixel, each pixel of the plurality of pixels is configured to be periodically evaluated at a frame rate, and each pixel of the plurality of pixels comprises at least one output, the at least one output comprises an analog output that provides an output signal to peripheral circuitry only when the value associated with each pixel has changed above a threshold level since the previous evaluation of the pixel.
