New imaging sensors for ADAS applications

0

Many ADAS and AD driving applications rely on the use of high-resolution imaging sensors, with the resolution of these units key to enabling accurate hazard recognition. In a move it says will help enable the next generation of AD systems, imaging specialist SmartSens has launched two advanced automotive CMOS image sensors, the SC100AT and SC410GS. The first of these sensors will form the basis of a new Automotive Series, which the company says is optimized to deliver fast, clear, and high-quality video in complex environments.

The SC100AT carries AEC-Q100 certification and features an ultra-high dynamic range of up to 140dB, to improve performance in variable lighting conditions. SmartSens says the unit incorporates its proprietary PixGain HDR technology giving the ability to produce readout noise levels as low as 0.58e-, giving clear night-vision in low-light environments. The sensor’s intended primary use cases include blind-spot monitoring, side-view mirror replacement, parking assistance, driving recording, back-up monitoring, and vehicle surround view.

The SC410GS meanwhile is the latest solution in the company’s SmartGS Series and uses 4 million BSI pixels compared with the 3 million that are commonly used. Thanks to proprietary global shutter technology, it is said to accurately capture fast-moving objects with no tail shadows or image distortion.

Together, SmartSens says these attributes significantly improve the efficiency of image recognition systems and traffic management applications—such as highway bayonet cameras, traffic junction monitoring, and parking lot toll bayonets—by quickly and accurately capturing detailed information in dark and high-speed traffic environments. The HDR technology behind the high-sensitivity BSI pixel also processes up to 12000mV/Lux-s, helping to resolve overexposures of signal lights at night.
