Sensor Enables Single Camera for 2-in-1 Convertible Laptops, Along With Greater Accuracy for Infrared Facial Recognition and High Quality Color Selfie Photos and Videoconferencing
SANTA CLARA, Calif. — May 21, 2019 — OMNIVISION Technologies, Inc., a leading developer of advanced digital imaging solutions, today announced the OV5678—the industry’s first 5MP RGB-Ir image sensor for 2-in-1 convertible laptops. This sensor enables a single camera with greater accuracy for infrared (IR) Windows Hello facial authentication as well as high quality color (RGB) images for selfies and videoconferencing. Combining IR and color imaging allows designers to create more compact, thinner 2-in-1 convertible laptops with greater functionality.
“Previously, Windows Hello facial authentication was not commonly found in 2-in-1 convertible laptops, as it required a second camera for IR functionality,” said Jason Chiang, product marketing manager at OMNIVISION. “The OV5678 eliminates the need for a second camera by combining RGB and IR capabilities in a single 5MP sensor, saving space while increasing value.”
To ensure high quality color images, the OV5678 is built on OMNIVISION’s 1.12 micron PureCel®Plus pixel architecture with deep trench isolation for greatly reduced color crosstalk. Additionally, its buried color filter array (BCFA) has a high tolerance for collecting light with various incident light angles.
The PureCel®Plus architecture also utilizes thicker silicon to improve quantum efficiency when capturing images using near-infrared light outside the visible spectrum. This is accomplished with only 1.3MP, which is a quarter of the OV5678 sensor’s full resolution. This IR performance enables machine vision applications such as Windows Hello facial authentication. It can also be used to perform eye tracking for reduced power consumption when the user is not viewing the screen. Eye tracking can also enable user warnings about eye fatigue from looking at the screen for an extended period of time.
The OV5678 is available now for samples and volume production, along with an evaluation kit. To learn more, visit OMNIVISION’s VIP suite at Computex, May 28-30. For those not attending, contact your OMNIVISION sales representative for more information: www.ovt.com/contact-sales.
