A camera that only detects changing pixels.
Movements are captured digitally while static information is ignored.
In contrast to conventional industrial cameras, which generate complete megapixel image data, the uEye EVS recognizes only contrast changes at each individual sensor pixel. These changes are transferred as independent events in real time, while motionless data is completely omitted.
The event-based vision sensor (EVS) was developed by Sony and Prophesee.

The slightly different sensor
With its unique event-based sensor technology, it only captures the relevant motion in the image: Where, when and how. Each pixel is basically a highly sensitive motion detector.
- 1280 x 720 asynchronous intelligent pixels
- Light sensitive up to 40mlux with 120dB HDR
- Scene-controlled events with 1μs time resolution
- Variable amount of data (10x to 1000x less than image-based sensors)
Features and applications
Detecting extremely fast processes
The temporal resolution, i.e. the minimum measurable time difference between two consecutive pixel events, is less than 100µs. This means that even the fastest movements can be captured with a comparable image-based frame rate of more than 10,000 FPS without motion blur. The result is no more “blind spots” between images.
Application examples:
- High-speed counting
- Analyze vibration frequencies and vibration patterns
- Super slow motion for analyzing finest movement dynamics
Extremely high dynamic range
See in the dark! The uEye EVS ensures results even under almost no light. Thanks to the pixel technology, the Sony IMX636 recognizes contrast changes even from 0.08 lux. Due to the logarithmic processing of high light values, the sensitivity exceeds that of image-based sensors even in very bright scenes.
Application examples:
- Process monitoring in complex lighting situations
- HDR driving assistance systems
- "Images + Events", sharp images even in poor lighting conditions and at high speeds thanks to synchronization of RGB and EVS camera
Results instead of raw data
Inspired by the human eye, the neuromorphic sensor technology from Sony and Prophesee only captures pixel motion and transfers this data with coordinates and a time stamp. Instead of the brightness values of each pixel, usable results are directly available.
Application examples:
- Track moving objects
- Analyze smallest particle movements
Efficient data processing
As only changes are captured and static areas are ignored, the amount of data to be processed is significantly reduced compared to image-based cameras. This saves memory and computing time.
Application examples:
- Embedded motion analysis supported by native motion segmentation
- Continuous traffic data acquisition
