Systems and methods for selectively modifying gating rate in single photon avalanche diodes

A method for selectively modifying gating rate in a single photon avalanche diode (SPAD), the method comprising:

• accessing first frame metadata associated with a first image frame, the first image frame being captured by performing a first plurality of gate operations to configure a SPAD array to enable photon detection over a frame capture time period, the first plurality of gate operations being performed at a first gating rate such that the first plurality of gate operations comprises a first quantity of gate operations performed over the frame capture time period, wherein the first frame metadata comprises a data structure indicating dynamic range of a captured scene;
• defining a second gating rate for capturing one or more subsequent image frames based on the data structure indicating dynamic range of the captured scene of the first frame metadata;
• and
• capturing a second image frame by performing a second plurality of gate operations to configure the SPAD array to enable photon detection at the second gating rate.

One or more hardware storage devices storing instructions that are executable by one or more processors of a system to configure the system to selectively modify gating rate in a single photon avalanche diode (SPAD) by configuring the system to:

• access first frame metadata associated with a first image frame, the first image frame being captured by performing a first plurality of gate operations to configure a SPAD array to enable photon detection over a frame capture time period, the first plurality of gate operations being performed at a first gating rate such that the first plurality of gate operations comprises a first quantity of gate operations performed over the frame capture time period, wherein the first frame metadata comprises temperature information associated with the performing of the first plurality of gate operations;
• define a second gating rate based on the first frame metadata;
• and
• capture a second image frame by performing a second plurality of gate operations to configure the SPAD array to enable photon detection at the second gating rate.
