OMNIVISION Achieves Two Sensor Firsts | Business

Semiconductor technology and digital image company OMNIVISION has developed pixel technology that is smaller than the wavelength of red light. The company’s OVBOA is a 200-MP image sensor with a pixel size of 0.56 μm. It is designed for rear-facing main cameras in high-end smartphones. The device features 16-cell binning capability, enabling it to achieve video capture of 12.5-MP/4K at 120 fps. The technology additionally features 100% quad phase detection (QPD) for more effective autofocus.

According to Arun Jayaseelan, senior product marketing manager at OMNIVISION, OVB0A’s 0.56-µm pixel is the first in the world smaller than the wavelength of red light.

“Leveraging our PureCel Plus-S stacked-die technology, we can maintain extremely high resolution in the smaller 0.56-µm pixel size, packing 200 million pixels into a 1/1.4-in. optical form factor,” Jayaseelan said.

In addition to a video capture of 12.5-MP/4K at 120 fps, the sensor achieves 12.5-MP/4K at 60 fps with 2-exposure staggered HDR timing. An on-chip re-mosaic function enables 8K video and 2× crop zoom (with HDR) at 12.5 MP.

Samples of the image sensor will be available in the fourth quarter of 2022.

In a separate development, OMNIVISION announced what it said is the industry’s first and only three-layer stacked BSI global shutter (GS) image sensor. The OG0TB is for eye and face tracking in AR/VR/MR devices. The device features a package size of 1.64 mm × 1.64 mm. It has a 2.2-μm pixel in a 1/14.46-in. optical format. It features 400 × 400 resolution and ultralow power consumption, ideal for some of the smallest and lightest battery-powered wearables such as eye goggles and glasses, according to the company.

“Ultralow power consumption is critical for these battery-powered devices, which can have 10 or more cameras per system. Our OG0TB BSI GS image sensor consumes less than 7.2 mW at 30 frames per second,” said David Shin, staff product marketing manager of IoT/Emerging at OMNIVISION.

The latest developments build on previous results that the company has reported in the last two years. OMNIVISION announced its 0.61-μm pixel 4K image sensor in May 2021. Earlier in 2021, the company reported it had quadrupled the resolution and reduced the size of what had been the world’s smallest commercial image sensor.

Samples of the OG0TB GS image sensor will be available in the third quarter of 2022, and mass production is expected in the second half of 2023.
