Claim 19:
20. A system for adding persistence to single photon avalanche diode (SPAD) imagery, the system comprising:
one or more processors; and
one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the system to add persistence to SPAD imagery by configuring the system to:
access a plurality of sequentially captured image frames, each image frame of the plurality of sequentially captured image frames being associated with a respective capture timepoint;
measure a brightness of at least a portion of a particular image frame of the plurality of sequentially captured image frames;
determine a persistence term for the portion of the particular image frame based on the brightness of the portion of the particular image frame; and
generate a composite image based on the plurality of spatially aligned sequentially captured image frames and the persistence term, wherein the persistence term defines a contribution of each of the plurality of sequentially captured image frames to the composite image.
