For the first time ever, Omnivision is bringing 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 1.64- x 1.64-mm, the OG0TC is an ultra-small and low-power image sensor for optimizing 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 the 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 is built on PureCel®Plus-S stacked-die technology developed by Omnivision and features patented DCG™ HDR technology that offers 400 x 400 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.

The image sensor consumes less than 40% of the power at 30 frames per second (fps) compared with the previous-generation sensor. Further, its high modulation transfer function enables sharper images with greater contrast and more detail. The sensor supports a flexible interface, including MIPI with multi-drop, CPHY, etc.

The OG0TC GS image sensor for AR/VR/MR applications is available now for sampling and is in mass production.
