CPC H04N 25/46 (2023.01) [H04N 25/42 (2023.01); H04N 25/75 (2023.01)] | 20 Claims |
1. A system comprising:
an array of light detectors, wherein the array of light detectors comprises a plurality of sets of adjacent light detectors, and wherein each set of adjacent light detectors comprises at least two adjacent light detectors;
a light detector sampling circuit connected to the array of light detectors;
a plurality of capacitors connected in parallel to an output of the light detector sampling circuit via a common node; and
a controller, wherein the controller is configured to perform a set of functions comprising:
selecting a first set of capacitors from the plurality of capacitors for charging at a first time;
selecting a second set of capacitors from the plurality of capacitors for discharging at a second time, wherein the second set of capacitors is different from the first set of capacitors;
sampling an output of the second set of capacitors as they discharge, wherein the output of the second set of capacitors corresponds to a first set of adjacent light detectors; and
determining, based on sampling the output of the second set of capacitors, a collective intensity of light received by the first set of adjacent light detectors.
