FRAME-BASED: A conventional camera takes an arbitrary number of frames per second, usually around 30 fps, in which all pixels record in synchrony regardless of what is going on in the scene. 

EVENT-BASED: In Prophesee Metavision® patented sensor (discover our Evaluation Kits), each pixel is independent and only records when it senses a change or movement. The information created does not arrive frame by frame. Rather, movement is captured as a continuous stream of information.

Prophesee sees between the frames, where all traditional frame-based systems are blind.

Prophesee technology functions like human vision. 

Something moving at high speed will be sampled at a high rate. Something that moves slowly will be sampled at a lower rate, and something that does not change, will not be sampled at all. No excess data is created.

This drastically reduces the power, latency and data processing requirements imposed by traditional frame-based systems.

Onboard is the first device to combine Prophesee’s patented sensor and AI algorithms.

Onboard has  embedded processing capabilities for Industry 4.0 applications, such as vibration measurement or high-speed counting. 

It is now possible to perform theses tasks using minimal power and computational requirements thanks to the very nature of event-based vision, which perceives all the essential information, while overlooking the irrelevant.
