Abstract
A ranging device includes an array of photon detection devices adapted to receive an optical signal reflected by an object in an image scene. First and second logic devices are adapted to respectively combine the outputs of first and second pluralities of the photon detection devices. A first range detection circuit is coupled to outputs of the first and second logic devices and a first counter is coupled to the output of the first logic device and adapted to generate a first pixel value by counting events generated by the first plurality of photon detection devices. A second counter is coupled to the output of the second logic device and is adapted to generate a second pixel value by counting events generated by the second plurality of photon detection devices. The first and second pixel values may be used in estimating a range to the object in the image scene.
