Intended for eye and face tracking in AR/VR/MR consumer headsets and glasses it is the first time that OMNIVISION has brought its patented DCG high dynamic range (HDR) technology to the AR/VR/MR market in the 2.2-micron (µm) pixel OG0TC GS image sensor.
With a package size of just 1.64mm x 1.64mm, the device is an ultra-small and low-power image sensor that’s intended for optimising primarily inward-facing tracking cameras. This small form factor is key to industrial designs as multiple cameras are required for tracking all aspects of the face (eyes, brows, lips, etc.). 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,” said 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.”
Key features of the OG0TC image sensor include:
· The sensor is built on OMNIVISION’s PureCel Plus-S stacked-die technology.
· It features OMNIVISION’s patented DCG HDR technology and offers 400x400 resolution with a 2.2µm pixel in a 1/14.46-inch optical format.
· Nyxel technology enables the best quantum efficiency at the 940nm near-infrared (NIR) wavelength for sharp, accurate images of moving objects.
· It consumes less than 40% of the power at 30 frames per second (fps) compared with the previous-generation sensor.
· The sensor’s high modulation transfer function enables sharper images with greater contrast and more detail.
· It supports a flexible interface, including MIPI with multi-drop, CPHY, etc.
Patel added, “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.”
The OG0TC GS image sensor is available now for sampling and is in mass production.
