Inspired by the human retina, Prophesee’s event-based Metavision sensor comprises 300,000 independent and asynchronous pixels that are responsive to low contrast, transient events. These pixels are essentially relative-change detectors, and activate independently according to any change in contrast detected in a scene. When activated, the pixels create a stream of time-stamped events in which their location within the sensor and the direction of the change in brightness - event-on or event-off - are encoded.

‘We have software algorithms that mimic the way the brain leverages visual information... Each intelligent pixel is triggered by motion and decides when to activate,’ explained Guillaume Butin, marketing director at Prophesee. ‘One pixel activating is an event, and we only see what moves.’
