High-Res Image Sensors Exploit NIR+

ON Semiconductor introduces what it’s calling the first CMOS image sensors to feature its Near Infra-Red+ (NIR+) technology, which effectively combines high dynamic range (HDR) with enhanced low light performance to enable high-end security and surveillance cameras. The AR0522 is a 1/2.5-inch 5.1 Megapixel (MP) image sensor based on a 2.2 micrometer (μm) Back Side Illuminated (BSI) pixel technology platform, developed for industrial applications that require high resolution, high quality video capture in low light conditions. The AR0522 image sensor delivers approximately twice the sensitivity in the near Infra-Red wavelength of the existing AR0521 image sensor.

 

The AR0431 is a 1/3.2-inch 4 MP sensor based on a 2 μm BSI pixel technology platform. Offering versatile low power modes and a frame rate of up to 120 fps, it is perfect for applications where slow-motion video capture is required. Its low operating power makes it ideal for battery-powered security cameras, as well as action/sports cameras, in-car DVRs and general surveillance cameras.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

ON Semiconductor developed NIR+ technology to increase the Quantum Efficiency (QE) of the sensors in the near Infra-Red region without sacrificing color fidelity in the visible spectrum. Reportedly, through this technique, security cameras can use fewer IR LEDs on BOM driven at lower voltages and still achieve high quality images in low light and NIR conditions.

 

Engineering samples of the AR0522 are available now in a 12 mm x 12 mm mPLCC package, with mass production planned for May 2018. Engineering samples of the AR0431 will be available later this month in a 10 mm x 10 mm mPLCC package, with mass production starting in July. If you got a minute or two, take a gander at the AR0522 datasheet and AR0431 datasheet.
