描述 Description

OmniVision's OV5678 is the industry's first 5MP RGB-Ir image sensor for 2-in-1 convertible laptops. The 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. To ensure high quality color images, the OV5678 is built on OmniVision's 1.12?μm 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 isn't 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.
