OMNIVISION’s OV9284 is a 1 megapixel global shutter image sensor that is ideal for in-cabin camera modules in passenger vehicles, where driver state monitoring (DSM) and passenger-monitoring cameras need to be extremely small and unobtrusive, while complying with new, stringent safety regulations. 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. The OV9284 is the industry’s first image sensor with the right balance of cost effectiveness, small form factor, high-quality imaging, and advanced features to meet the needs for incorporating DSM in the mainstream automotive market.
The OV9284 also offers 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. This sensor consumes only 90 mW of power at 60 frames per second (fps), which is 30% lower than the nearest competitor. Additionally, the high-speed global shutter sensor with OmniPixel®3-GS technology offers 1280 x 800 resolution at video speeds of up to 120 fps.
This sensor comes in a compact automotive chip-scale package (a-CSP™), which measures 5.2 x 4.5 mm for smaller lens designs. Its 27-degree chief ray angle enables a wider viewing angle in a thinner package, allowing for greater flexibility with camera design and placement.
