OmniVision and GEO Semiconductor partner on cabin monitoring systems
OmniVision Technologies and GEO Semiconductor announced a joint solution for capturing and processing high-quality color (RGB) and infrared (IR) automotive interior images, day and night, with one camera. This solution combines OmniVision’s OV2778 2MP RGB-Ir image sensor, which is designed to offer high sensitivity across all lighting conditions, in tandem with GEO’s GW5200, which provides dedicated hardware for processing the RGB-IR sensor. The companies say the result is high-quality video for both machine vision and viewing applications to provide easily integrated solutions for the detection of objects and unattended children, remote monitoring, and recording in ride-hailing and robo-taxi vehicles.
The OV2778 image sensor is built on OmniVision’s 2.8-micron OmniBSI-2 Deep Well pixel technology, which delivers a 16-bit linear output from a single exposure with low-light sensitivity. Additionally, the GW5200’s integrated image signal processor (ISP) has an advanced noise filter that further enhances low-light image quality. Both devices combined reportedly consume less than 750 mW in typical operating conditions.
The GW5200 processor can support the full 120 dB high dynamic range (HDR) output of the OV2778 image sensor, which provides high-quality image detail in scenarios with both bright and dark light scenes. The GW5200 includes GEO’s 5th-generation eWARP geometric processor to dewarp fisheye lenses exceeding a 180° field of view. For top color imaging performance across varying lighting conditions, the OV2778 sensor integrates an RGB-IR, 4x4 pattern color filter and an external frame synchronization capability.
The OV2778 image sensor is offered in a 6.5 x 5.7 mm automotive CSP. The GW5200 camera video processor is offered in a 7 x 7 mm BGA package.
Both devices are available now, and both provide advanced ASIL functional safety and AEC-Q100 Grade 2 certification for automotive applications.
