Claimed to be the world’s smallest and most power efficient event-based vison sensor, the GenX320 brings intelligence, privacy and safety to consumer edge AI devices, claimed Prophesee.

The company’s latest event-based Metavision sensor has low power, low latency, high flexibility for efficient integration in AR/VR headsets, security and monitoring/detection systems, touchless displays, eye tracking features and always-on smart IoT devices, said the company. 

It is, said Prophesee, the industry’s first event-based vision sensor developed specifically for integration into low power edge AI vision devices. The fifth generation Metavision sensor is available in a tiny 3.0 x 4.0mm die size.   

The 320 x 320 6.3 micron pixel BSI stacked event-based vision sensor offers a tiny 1/5 inch optical format. It has been developed with a specific focus on the requirements of efficient integration of event sensing in energy-, compute- and size-constrained embedded at-the-edge vision systems. It enables robust, high-speed vision at ultra-low power and in challenging operating and lighting conditions, added the company.

Features of the GenX320 include low latency microsecond resolution timestamping of events with flexible data formatting. There are also on-chip intelligent power management modes reduce power consumption to as low as 36 microW and enable smart wake-on-events. Deep sleep and standby modes are also featured.

Ease of integration/interfacing with standard SoCs with multiple integrated event data pre-processing, filtering, and formatting functions minimises external processing overhead. In addition, MIPI or CPI data output interfaces offer low-latency connectivity to embedded processing platforms, including low power microcontrollers and modern neuromorphic processor architectures.

The GenX320 is AI-ready, with on-chip histogram output that is compatible with multiple AI accelerators. For security, sensor-level privacy is enabled via the event sensor’s inherent sparse frameless event data with inherent static scene removal.

There is also native compatibility with Prophesee Metavision Intelligence event-based vision software suite, which is available free of charge and is used by community of 10,000+ users.

The high speed eye-tracking allows for foveated rendering for seamless interaction in AR/VR/XR headsets. The low latency touch-free human machine interface is suitable for consumer devices (TVs, laptops, game consoles, smart home appliances and devices and smart displays. The event-based sensor is also suitable for smart presence detection and people counting in IoT cameras and other devices as well as for always-on area monitoring systems and fall detection cameras in homes and health facilities.

The GenX320 is available for purchase from Prophesee and its sales partners. It is supported by a complete range of development tools, including a comprehensive evaluation kit housing a chip on board (COB) GenX320 module, or a compact optical flex module. In addition, Prophesee is offering a range of adapter kits that enable seamless connectivity to a large range of embedded platforms, such as a STM32 MCU, enabling faster time-to-market.

Prophesee creates neuromorphic vision systems. It developed an event-based vision approach to machine vision which allows for significant reductions of power, latency and data processing requirements to reveal what was invisible to traditional frame-based sensors until now. Prophesee’s patented Metavision sensors and algorithms mimic how the human eye and brain work to dramatically improve efficiency in areas such as autonomous vehicles, industrial automation, IoT, mobile and AR/VR. Prophesee is based in Paris, with local offices in Grenoble, Shanghai, Tokyo and Silicon Valley.
