Biometric Security for Next-Generation
Smartphones, Tablets and Notebooks
OmniVision's OV2281 is a new PureCel® sensor that
brings enhanced biometric security functionality to
mobile devices. The low-power, ultra-compact OV2281
leverages a 1.12-micron pixel with PureCel technology
to enable accurate, reliable iris recognition for
smartphones, tablets and notebooks.
When recording full-resolution 1944 x 1944 video at
30 fps, the sensor requires just 126 mW, and supports
ultra-low power mode to reduce power consumption to
approximately 25 mW. Additionally, the OV2281
features optimized IR sensitivity to produce a clear,
fully stable image in difficult, low-light conditions.
The 1/7.5-inch OV2281 PureCel sensor can record
1080p high-definition (HD) video at 60 frames per
second (fps) in both landscape and portrait modes to
support apps with horizontal or vertical orientation.
The OV2281 sensor fits into a 5.5 x 5.5 mm module with
a z-height of less than 4.5 mm.
