Event-Based Image Sensors

A different kind of imaging

What makes event based image sensors different

Event-based vision sensors operate differently from traditional frame-based sensors by transmitting changes in light intensity per pixel rather than full image frames. 

This results in a continuous stream of temporal event data, enabling ultra-fast effective frame rateslow latency, and reduced data bandwidth—as only relevant changes are captured. 

As an authorized distributor, RESTAR FRAMOS supplies Sony event-based sensors and Prophesee solutions, supporting the development of advanced, high-speed vision applications. 

Key features of Event-Based Vision Sensors

Event-based sensors generate asynchronous pixel events instead of frames.  

Each event includes:  

  • X, Y location 
  • Polarity(intensity increase/decrease) 
  • TimestampEvents are triggered only when intensity change exceeds a threshold, meaning data is captured only where change occurs 

Benefits:  

  • Sparse, efficient data streams 
  • Adaptive bandwidth usage 
  • Compatible withFPGA, ISP, and AI/neuromorphic processing

EVS is not limited by frame timing, enabling extremely high temporal resolution and near-zero latency 

Key advantages: 

  • Microsecond-level motion capture 
  • Software-defined frame reconstruction 
  • Can be combined withframe-based sensorsfor context  

Ideal for capturing fast events without requiring high-speed cameras.

EVS achieves very high dynamic range by detecting relative intensity changes 

Key characteristics:  

  • Pixels continuouslyadapt to lighting conditions 
  • Nofull-well saturation limitations 
  • Handlessimultaneous bright and dark regions 

 

Enables reliable imaging in high-contrast and rapidly changing environments.
