Classification: CPC G  H | IPC G  H

Claim 3:
4. A light receiving element, comprising:
a pixel array in which a plurality of pixels is arranged in a matrix; and
a pixel driving unit configured to control respective pixels of the pixel array to be active pixels or non-active pixels,
wherein the pixel includes:
a single photon avalanche diode (SPAD);
a resistance component connected to the SPAD in series;
an output unit configured to output a detection signal indicating incidence of a photon on the SPAD;
a first transistor which is switched on or off in accordance with control of the pixels to be the active pixels or the non-active pixels; and
a second transistor connected to the first transistor in series,
wherein the output unit includes a CMOS inverter, and
a threshold voltage of the second transistor is lower than a threshold voltage of the CMOS inverter.
