Smallest-footprint sensor for presence detection, facial recognition and always-on

OMNIVISION has announced the new OV0TA1B monochrome/infrared CMOS image sensor, the first and only solution that fits 3mm module Y dimension and smaller notebook computers, webcams, and IoT devices. The low-power sensor is ideal for AI-based HPD, facial authentication, and always-on (AON) technology.

"Stand-alone 940nm IR cameras are becoming more mainstream, especially in the latest generation of ultrathin-bezel design notebooks that feature personalised AI features and require HPD and facial authentication capabilities," said Jason Chiang, staff marketing manager computing, OMNIVISION. "The OV0TA1B is the newest mono/IR sensor in our computing portfolio designed to be a cost-effective, ultra-small-footprint device; it is ideal for HPD and facial authentication in 3mm module Y bezel and smaller designs. The ultra-small size of the OV0TA1B sensor also makes it useful for webcams and IoT devices, like those used for people and traffic counting."

The sensor comes in IR or mono, depending on the customers' design needs (in cases where the system has another stand-alone RGB camera). It features a 2µm pixel based on PureCel pixel technology for high-performance sensitivity and MTF (modulation transfer function), allowing it to maintain the HPD and facial authentication.

The sensor delivers 440 x 360 resolution at 30fps. It is a low-power 220x180 (2.58mW@3fps) image sensor in a 1/15.8" optical format.
