Image Sensors Enhance Next-Gen Auto Safety Systems

STMicroelectronics’ latest automotive global shutter image sensors, the VG5661 and VG5761, perform driver monitoring. The image sensors enhance monitoring of vehicle occupants by capturing the scene as illuminated from the camera, eliminating unpredictable external effects such as sunlight or street lighting.

 

The components’ high image quality sharpens the responses of driver-monitoring systems, especially under near-infrared illumination close to 940 nm and makes possible new features such as assessing driver attention, passenger comfort, or child behavior. The sensors embed the company’s automotive global shutter technology that strongly minimizes the illumination power consumption, even in high dynamic range mode.

SENSORS EXPO & CONFERENCE

Sensors 2019 Hits Silicon Valley June 25-27!

Join 7,000+ engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, 10 new and updated tracks, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

Working with Jungo, ST recently showed how the new sensors enable next-generation driver assistance. Jungo’s driver-monitoring software leverages the images from ST’s sensors to monitor the position and movements of all occupants, assessing the driver’s condition and accurately surveying the location and movements of other vehicle occupants.

 

The VG5661 and VG5761 are 1.6 Mpixel and 2.3 Mpixel automotive global shutter sensors, respectively. Unlike the rolling shutter which continuously reads data directly from pixels one row at a time, global shutter captures the data at all pixels simultaneously. Both are supplied in standard BGA packages, or as bare die for direct integration in automotive OEM systems produced in high volumes. They are qualified to AEC-Q100 grade 2 and include complex safety-integrity features as required for an ASIL-B camera system in accordance with the automotive safety standard ISO 26262. For more details, checkout the VG5661 and VG5761 datasheets. Also visit STMicroelectronics.
