HDR image sensors offer improved night vision
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. It 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 2.0 μm BSI pixel technology platform. Offering versatile low power modes and a frame rate of up to 120 fps, it suits applications where slow motion video capture is required. Its low operating power makes it fit for battery-powered security cameras, as well as action/sports cameras, in-car DVRs and general surveillance cameras.
The NIR+ technology was developed to increase the Quantum Efficiency (QE) of the sensors in the near Infra-Red region without sacrificing colour fidelity in the visible spectrum. 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.
The AR0522 engineering samples are available now in a 12x12mm mPLCC package, with mass production planned for May 2018. Engineering samples of the AR0431 will be available later in April 2018 in a 10x10mm mPLCC package, with mass production starting in July 2018.
