Event Based Image Sensors
EVS
Event-based Vision Sensors (EVS) help alleviate this issue by only sending data from pixels who have detected a change in intensity. This allows them to minimize the volume of data that is transmitted over the sensor’s data bus while minimizing the processing resources need to analyze the image. On top of this, individual pixel autonomously responds to illuminance changes allowing the sensor to detect small and/or high frequency changes with lower bandwidth requirements.
