CAMERA SENSOR WITH EVENT TOKEN BASED IMAGE CAPTURE AND RECONSTRUCTION

摘要

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

1. A camera sensor with event token image capture and reconstruction comprising:
a photodetector for detecting light from a portion of a scene and producing a signal indicative of the light; an integrator for accumulating charge resulting from the signal output by the photodetector; an in pixel processor for, in response to each accumulation by the integrator of the predetermined level of charge, resetting the integrator and generating an event token; a communication pipeline for communicating the event tokens from the in-pixel processor for downstream processing; and a post processor for receiving the event tokens and determining an output intensity based on a number of reset events and a time between at least two of the event tokens.
