Omnivision has claimed the smallest and lowest-power global shutter (GS) image sensor for eye and face tracking in AR/VR/MR consumer headsets and glasses with the introduction of the 2.2-micron (µm) pixel OG0TC BSI GS image sensor. The combination of small size and low power consumption, along with high-performance imaging, make the OG0TC suited for AR/VR/MR tracking cameras.

The OG0TC is the first GS image sensor for AR/VR/MR that uses the company’s on-chip DCG high dynamic range (HDR) technology. Delivering ghost-free HDR imaging, the OG0TC offers a 400 × 400 resolution with a 2.2-µm pixel in a 1/14.46-inch optical format. The image sensor is built on Omnivision’s PureCel Plus-S stacked-die technology and leverages Nyxel technology for the best quantum efficiency at 940-nm near-infrared (NIR) wavelength for sharp images of moving objects.
The sensor also offers a high modulation transfer (MTF) function that enables sharper images with greater contrast and more detail, the company said.
The ultra-small, with a package size of 1.64 × 1.64 mm, and low-power image sensor targets inward-facing tracking cameras. This small form factor is suited for industrial designs that use multiple cameras for tracking the face, including eyes, brows and lips. In addition, it consumes less than 40% of the power at 30 frames per second (fps) compared with the previous-generation sensor.

The OG0TC is pin-to-pin compatible with the previous-generation BSI GS image sensor for easy upgrades. It also offers a flexible interface, including MIPI with multi-drop and C-PHY.
The OG0TC is available now for sampling and is in mass production.
