Abstract
An apparatus and method for determining a distance to an object using a binary, event-based image sensor. In one aspect, the image sensor includes memory circuitry and address decode circuitry. In one aspect, activation of a photodiode of the image sensor array by receipt of one or more photons is able to be used directly as an input to logic circuitry. In one embodiment, the image sensor includes photodiodes operating in an avalanche photodiode mode or Geiger mode. In one embodiment, the imaging sensor includes photodiodes operating as thresholded integrating pixels. The imaging sensor can be fabricated from one or more substrates having at least a first and a second voltage portion.
