The global shutter image sensor for AR/VR/MR offers HDR, precise tracking, low power, and a compact design for next-generation consumer technology.
OMNIVISION has launched theOG0TC BSI global shutter (GS) image sensor. This product is designed for eye and face tracking in AR/VR/MR consumer headsets and glasses. This marks the first introduction of OMNIVISION’s patented DCG high dynamic range (HDR) technology into the AR/VR/MR sector, featured in the 2.2-micron pixel GS image sensor.
The sensor is described as a 1/14.46-inch B&W 160 Kpixel (400 x 400) CMOS Image Sensor. It incorporates PureCelPlus‑S, Global Shutter, and Nyxel Technologies, specifically tailored for tracking applications in consumer AR/VR/MR devices.
The OG0TC is notably compact, with dimensions of only 1.64 mm x 1.64 mm, making it an ultra-small, low-power option ideal for primarily inward-facing tracking cameras in space-constrained environments. This sensor supports multiple camera setups necessary for comprehensive facial tracking (including eyes, brows, lips, etc.).
Some of the characteristics of the OG0TC image sensor include:
- Construction using OMNIVISION’s advanced PureCelPlus‑S stacked-die technology.
- Incorporation of patented DCG™ HDR technology, ensuring high-quality, ghost-free images and a resolution of 400 x 400 with a 2.2 µm pixel size.
- Nyxel technology, which optimizes quantum efficiency at the 940 nm NIR wavelength, is crucial for capturing precise images of dynamic scenes.
- High modulation transfer function for images with enhanced sharpness, contrast, and detail.
- Support for a flexible interface, including MIPI with multi-drop and CPHY options.
“Ultra-low power consumption is critical for AR/VR battery-powered devices, and our OG0TC BSI GS image sensor reduces power by more than 40% over our previous-generation OG0TB sensor, which is already an extremely low-power device,” says Devang Patel, marketing director – IoT/Emerging, OMNIVISION. “Pin-to-pin compatibility makes the upgrade to the OG0TC easy for our customers, so they do not need to make any change to their design to save power and enjoy new features like DCG technology.”
