Utility
Time-resolved quanta image sensor
8 Mar 22
Multi-stage auto-zeroing signal amplifiers are deployed within event-shuttering pixels of a quanta image sensor (QIS) pixel array to enable reliable per-pixel reporting of photonic events, down to resolution of a single photon strike, for each of a continuous sequence of sub-microsecond event-detection intervals.

Utility
Scalable-pixel-size image sensor
7 Sep 21
Photodetection elements within an integrated-circuit pixel array are dynamically configurable to any of at least three uniform-aspect-ratio, size-scaled pixel footprints through read-out-time control of in-pixel transfer gates associated with respective photodetection elements and binning transistors coupled between the transfer gates for respective clusters of the photodetection elements and a shared reset node.

Utility
Column-interleaved pixel array
12 Oct 20
Shared-readout pixels conventionally disposed in two or more physical columns of a pixel array are spatially interleaved (merged) within a single physical column to yield a pixel array in which each physical pixel column includes two or more logical columns of shared-readout pixels coupled to respective logical-column output lines.

Utility
Split-readout image sensor
6 Apr 20
First and second readout circuits, each having a respective floating diffusion node, are coupled to a photodetection element within a pixel of an integrated-circuit image sensor.

Utility
High-sensitivity depth sensor with non-avalanche photodetector
2 Mar 20
A sensing device includes a light source to emit light, a light sensor to detect reflection of the emitted light and distance determination circuitry responsive to reflected-light detection within the light sensor.
