Sensor enables ghost-free HDR imaging

The OG0TC global-shutter image sensor from Omnivision brings the company’s DCG high dynamic range technology to AR/VR/MR tracking cameras. Intended for eye and face tracking, the backside-illuminated sensor’s on-chip single-exposure DCG extends dynamic range up to 140 dB, ensuring images are free of ghosting and motion artifacts.

Based on a stacked-die construction, the OG0TC sensor is just 1.64×1.64 mm. It offers a resolution of 400×400 pixels with a pixel size of 2.2 µm in a 1/14.46-in. optical format. This small, low-power CMOS sensor is designed primarily for inward-facing tracking cameras. Its small form factor is key to AR/VR designs, as multiple cameras are required for tracking all aspects of the face (eyes, brows, lips).

Ultra-low power consumption is crucial for AR/VR devices. The OG0TC image sensor cuts power usage by over 40% compared to the previous-generation OG0TB, while maintaining pin-to-pin compatibility for easy upgrades and adding features like DCG technology, according to Devang Patel, Marketing Director of IoT/Emerging, Omnivision.

Offered in a 16-pin chip-scale package, the OG0TC global-shutter image sensor is now available for sampling and in mass production.
