Developer of semiconductor solutions Omnivision has revealed two new pieces of componentry for its near-infrared (NIR) technology portfolio, consisting of the OX02C1S – a 2.5MP RGB‑IR BSI global shutter (GS) sensor for in-cabin driver and occupant monitoring systems (DMS and OMS) – and the OX01H1B – a 1.5MP mono (IR) GS sensor for driver monitoring systems (DMS).
Both new sensors feature a pixel size of 2.2µm and benefit from an NIR quantum efficiency (QE) at 36%. The units also offer low power consumption and high performance.
The OX02C1S and OX01H1B small-size automotive-grade sensors use OmniPixel4‑GS technology to enable simultaneous image detection in all pixels to accurately reproduce rapid motion without any deformation. Furthermore, both sensors have integrated ASIL B and cybersecurity to adhere to industry standards.
“Our OX02C1S and OX01H1B sensors are the newest additions to our in-cabin solutions portfolio, with the same features as the 5MP OX05B1S GS sensor that we introduced during the Consumer Electronics Show in 2022,” said Paul Wu, automotive product management and marketing manager, Omnivision. “All three sensors share the same pixel technology, so it’s a seamless process for automotive OEMs to incorporate any combination of them as solutions in their full line-up, from high-end to mainstream vehicles.”
“The CMOS image sensor market for automotive DMS and OMS can be divided into three distinct segments: digital cockpit, automated driving and NCAP/GSR (New Car Assessment Program/General Safety Regulation) compliance,” explained Colin Barnden, principal analyst at Semicast Research. “Performance requirements differ significantly for each. Designers must also consider sensor location, including rear-view mirror, steering column and center console. With the new OX02C1S and OX01H1B sensors, and existing OX05B1S, Omnivision provides auto makers with solutions for the total market.”
Wu added, “The OX02C1S is essentially a more economical and lower resolution (2.5MP) version of the OX05B1S for DMS and OMS, while the OX01H1B is a flexible 1.5MP solution for DMS that offers the ideal price/performance for OEMs that need flexibility to place the DMS camera into different locations within the vehicle based on their unique interior design.”
