OMNIVISION announces new OG0TC BSI global shutter (GS) image sensor for eye and face tracking in AR/VR/MR consumer headsets and glasses. The semiconductor solution provider brings its patented DCG high dynamic range (HDR) technology to the AR/VR/MR market for the first time in the 2.2-micron (µm) pixel OG0TC GS image sensor.
OC0TC comes in a package size of 1.64mm x 1.64mm and is an ultra-small and low-power image sensor that optimizes inward-facing tracking cameras. This small form factor is essential to industrial designs as multiple cameras are required for tracking all aspects of the face (eyes, brows, lips, and more). The OG0TC is pin-to-pin compatible with OMNIVISION’s previous-generation BSI GS image sensor for easy upgrades.
“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.”
The OG0TC image sensor, built on OMNIVISION’s PureCel Plus-S stacked-die technology, features the company’s patented DCG HDR technology and offers a 400×400 resolution with a 2.2µm pixel in a 1/14.46-inch optical format. Enhanced by Nyxel technology, it delivers superior quantum efficiency at the 940nm near-infrared (NIR) wavelength, ensuring sharp, accurate images of moving objects. Consuming less than 40% of the power at 30 frames per second (fps) compared to its predecessor, this sensor’s high modulation transfer function enables sharper images with greater contrast and detail. Additionally, it supports a flexible interface, including MIPI with multi-drop and CPHY options.
“We are excited to introduce our single-exposure DCG HDR technology for ghost-free image capture to the AR/VR market. It already has proven to be extremely successful in the security, mobile and automotive industries,” added Devang.
