5Mpixel RGB-IR global shutter sensor is a first for in-cabin monitoring
For simultaneous driver and occupant monitoring in vehicles, the OX05B1S has been introduced by Omnivision. It is claimed to be the smallest 2.2 micron pixel with the highest near infrared (NIR) sensitivity.
It is also believed to be the automotive industry’s first 5Mpixel RGB-IR BSI global shutter sensor for in-cabin driver monitoring systems (DMS). Despite its pixel size of just 2.2 micron, it offers 940nm NIR sensitivity for performance in extremely low light conditions. It has a wide field of view and enough pixels to view both the driver and occupants, adds the company. It is also claimed to be the first RGB-IR sensor for in-cabin monitoring to feature integrated cybersecurity.
The introduction supports the automotive industry’s transition to 5Mpixel operation and only one camera is needed instead of two for simultaneous driver and occupant monitoring systems, reducing complexity, cost and space,” points out Andy Hanvey, director of automotive marketing at Omnivision. The company adds that the OX05B1S was developed with “strong ecosystem partner support, working with companies such as Seeing Machines, to enable a complete, seamless solution for automotive OEMs”.
The sensor is based on Omnivision’s Nyxel NIR technology which uses novel silicon semiconductor architectures and processes to achieve the world’s best quantum efficiency (QE) at the 940nm NIR wavelength, claims the company. The OX05B1S has an NIR QE of 35 per cent which is four times the capability of the previous generation of sensor. This enables the OX05B1S to detect and recognise objects that other image sensors would miss under extremely low lighting conditions, to enhance in-cabin camera capabilities for occupant and driver monitoring and security. In other non-automotive systems it can be used to enhance selfie images and videoconferencing.
The sensor comes in Omnivision’s stacked a‑CSP package that is 50 per cent smaller than competitive products and allows for higher-performance image sensors in tighter camera spaces. It is also available in a reconstructed wafer option for designers who want to customise their own package.
The OX05B1S has an optional always on optional feature.
Samples are available now and the sensors will be in mass production in Q1 2023.
