Abstract
An apparatus includes a single photon avalanche diode pixel that includes a single photon avalanche diode and an output transistor configured to provide an analog output current from the single photon avalanche diode. The single photon avalanche diode pixel is configured to operate in a first mode to output a digital single photon detection event. The single photon avalanche diode pixel is further configured to operate in a second mode to output the analog output current indicating a level of illumination of the pixel.
