Advances in Event-Based Cameras

This was brought to my attention based on a project we addressed some time ago, the term 'event based camera'  was brought up as a potential solution.  To address the significant monitoring of lab work.    Here advances in the idea are described.  I am passing this on directly to those that were involved in that work, it may be relevant.

Prophesee’s Event-Based Camera Reaches High Resolution

There’s something inherently inefficient about the way video captures motion today. Cameras capture frame after frame at regular intervals, but most of the pixels in those frames don’t change from one to the other, and whatever is moving in those frames is only captured episodically.

Event-based cameras work differently; their pixels only react if they detect a change in the amount of light falling on them. They capture motion better than any other camera, while generating only a small amount of data and burning little power.

Paris-based startup Prophesee has been developing and selling event-based cameras since 2016, but the applications for their chips were limited. That’s because the circuitry surrounding the light-sensing element took up so much space that the imagers had a fairly low resolution. In a partnership announced this week at the IEEE International Solid-State Circuits Conference in San Francisco, Prophesee used Sony technology to put that circuitry on a separate chip that sits behind the pixels.
