OmniVision Technologies announced it has released the OV2281, a new PureCel sensor with improved biometric security functionality for mobile devices.
Build on OmniVision’s 1.12-micron pixel technology and optimized IR sensitivity, the low-power, compact OV2281 sensor provides accurate iris recognition capabilities for smartphones, tablets and notebooks, in both landscape and portrait orientations.
“With the convergence of digital identities, security concerns and mobile commerce, 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 1/7.5-inch OV2281 PureCel sensor is able to record 1080p high-definition video at 60 frames per second (FPS) in both portrait and landscape orientation, allowing it to support iris detection in either format.
When recording full-resolution 1920 x 1920 video at 30 FPS, the sensor requires just 120 mW. It also supports an ultra-low power mode that can reduce power consumption to approximately 25 mW.
The monochrome sensor offers significantly high IR sensitivity to generate clear and fully stable images in even low-light environments.
The OV2281 sensor, which is currently in volume production, fits into a 5.5 x 5.5 mm module with a z-height of less than 4.5 mm.
