Camera sensor with event token based image capture and reconstruction
Abstract:
The subject matter described herein includes a camera sensor with event token based image capture and reconstruction. The sensor includes a photodetector for capturing light from a portion of a scene and for producing a signal indicative of the light. An integrator is coupled to the photodetector for accumulating charge resulting from the signal output by the photodetector and can be reset each time the charge reaches a predetermined level. An in-pixel processor is coupled to the integrator for resetting the integrator and generating an event token each time the predetermined level of charge is accumulated. A communication pipeline communicates the event tokens for downstream processing. A postprocessor is coupled to the pipeline for receiving the event tokens and for determining output intensity for the portion of the scene being reconstructed based on a number of reset events and a time between at least two of the event tokens.
