Shutter Image Sensor Keeps An Eye On Driver And Passengers

OmniVision Technologies’ OV9284 1-Mpixel global shutter image sensor is promoted as being ideal for in-cabin camera modules in passenger vehicles. This is usually where driver state monitoring (DSM) and passenger-monitoring cameras need to be extremely small and unobtrusive, while complying with stringent safety regulations.


According to the company, the global automotive image sensor market is poised to experience accelerating growth because of increased automation and the new safety regulations imposed on level-3 semiautonomous vehicles. Semiautonomous vehicles use DSM to track the driver’s eye gaze and allow the vehicle to take control when the driver becomes drowsy or distracted. DSM is currently available in high-end cars, but over the next few years, the feature will migrate into mainstream vehicles, a market segment that is much more cost-sensitive.

The OV9284 claims to offer the industry’s best near-infrared (NIR) quantum efficiency (QE) in a driver-monitoring image sensor, with 12% at 940 nm, which allows designers to achieve sufficient illumination with fewer LEDs, thus reducing total system cost and power consumption. It consumes 90 mW of power at 60 fps, which is said to be 30% lower than the nearest competitor. Additionally, the high-speed global shutter sensor with OmniPixel3-GS technology offers 1280 x 800 resolution at video speeds of up to 120 fps.


The sensor comes in a chip-scale package (CSP) that measures 5237 µm x 4463 µm. For deeper vision and insights, he OV9284 image sensor is available now. For more information, visit OmniVision and email [email protected].
