The OV2281 has 1.12-micron pixels that can record 1080p high-definition video at 60 frames per second in both portrait and landscape orientation, thus supporting iris detection in either situation. When recording full-resolution 1920 x 1920 video at 30 fps, the sensor requires 126 mW. It also supports a low power mode that can reduce power consumption to approximately 25 mW. As a monochrome sensor, the OV2281 produces images in low-light conditions.

"Industry experts project that 13 billion biometric applications will be downloaded by 2.2 billion mobile users between 2014 and 2020," said Archie de Guzman, staff product manager at OmniVision. "In this context, iris detection appears poised to become the next trend in biometric security for mobile devices. The OV2281 therefore enters the market as an extremely compelling solution by offering accurate horizontal or vertical iris detection in a compact and power-efficient package."

The sensor fits into a 5.5 x 5.5-mm module with a z-height of less than 4.5 mm and is in volume production.
