Sony's New Event-based Vision Sensors (EVS) available through Macnica ATD Europe

Disruptive Sensors for Environment Perception made possible through collaboration between Sony and Prophesee.


Chatou/France, 23 November 2021. Macnica ATD Europe today announced to offer

the Event-based vision sensor (“EVS”) from its long-term distribution partner, Sony

Semiconductor Solutions Corporation (“Sony”). The two sensors IMX636 and IMX637

were made possible through collaboration between Sony and Prophesee, another

distribution partner of Macnica ATD Europe.


EVS realizes high-speed data output with low latency by limiting the output data to

luminance changes from each pixel, combined with information on pixel position

coordinates and time. Only the pixels that have detected a change in luminance for

the object can output data, allowing the sensor to immediately detect the luminance

changes with high-speed, low-latency, high-temporal-resolution while operating with

low power consumption. It represents a whole new approach compared to the

commonly used frame-based method, where the entire image is output at certain

intervals determined by the frame rate.


Application fields where the two new models of EVS specifically exploit their

advantages over frame-based sensors are for example sensing changes in sparks

produced during welding and metal cutting; and sensing slight changes in vibration and detecting abnormalities for use in predictive maintenance.


Macnica ATD Europe as a prime distribution partner of both Sony and Prophesee

covers the full cooperation on the EVS technology and offers technical support as

well as the free loan of evaluation kits in different versions from first “hands on”

evaluation to full performance evaluation (available in Q4). The cooperation also

covers the Metavision® Intelligence Suite from Prophesee, an event signal

processing software optimized for the sensors performance, which is available

through Macnica ATD Europe. Combining Sony’s event-based vision sensors with

this software will enable efficient application development and provide solutions for

various use cases.
