Cabin monitoring system combines RGB, IR on single sensor
GEO Semiconductor and Omnivsion have jointly developed a solution that simultaneously captures and processes high-quality color (RGB) and infrared (IR) automotive interior video from a single sensor.
The solution combines Omnivision’s OX05B1S 5MP RGB-IR image sensor with GEO’s upcoming GW6 Intelligent Camera Video Processor. The GW6 supports the full 5-MP RGB-IR 4×4 pattern of the OX05B1S running at 60FPS and provides two unique video streams for both computer vision and viewing applications. This results in an integrated in-cabin solution for the driver monitoring (DMS) and occupant monitoring (OMS) algorithms while utilizing only one high-resolution RGB-IR image sensor.
The OX05B1S image sensor is built on Omnivision’s 2.2-micron PureCelPlus‑S and Nyxel pixel technologies. Nyxel delivers the industry’s highest NIR quantum efficiency at 36% with a 3x boost from 12% in the previous generation, the vendor claims.
The GW6 camera video processor is developed on the TSMC 16nm automotive process and will be offered in a 7 x 7mm fcCSP package (video processing only) or a 17 x 17mm fcCSP package (neural network version). The OX05B1S image sensor is offered in a small package for the automotive in-cabin market segment – a 7.9 x 6.3mm automotive CSP.
The OX05B1S will be available in mass production in Q1 2023, with GW6 availability starting in 2023. Both provide advanced ASIL functional safety and AEC-Q100 Grade 2 certification for automotive applications.
The solution will be demoed at the GEO Semiconductor CES 2023 suite in Las Vegas.
