ON Semiconductor introduced their CMOS image sensor targeted for use in advanced video security cameras, especially the automotive industry. The AR0230AT image sensor is a 1/2.7-inch optical format device with high 105 decibel (dB) dynamic range that combines low-light capabilities with near-infrared (NIR) performance.https://cdn.specpick.com/images/photonics/onsemi_ar0230at_300.jpg712370
According to Sibel Yorulmaz, Line Manager at OnSemi’s distributor FRAMOS, the AR0230AT produces clear, sharp digital pictures, and has the ability to capture both continuous video and single frames that make it a good choice in a wide range of applications such as surveillance, HD video, and automotive scene viewing. Its extended operating temperature from -40°C to +105°C and iBGA packing requires less space. In addition, its lower thermal resistance is great for automotive challenges.
The image sensor enables capture of full high-definition (Full HD) 1080p video data at a rate of 30 frames-per-second (fps) or even 60 fps for less quality surveillances tasks. It includes integrated support for HDR video, with improved motion compensation, advanced local tone mapping (ALTM), and digital lateral overflow (DLO) to minimize motion artifacts and enhance HDR color reproduction. This complete HDR functionality ensures fast time to market for new HDR 1080p camera designs. Additionally, the AR0230AT provides interleaved T1/T2 output for those using third-party ISP HDR support.
ON Semiconductor’s proprietary dual-conversion gain 3.0 micron (µm) DR-Pix™ pixel technology is used to enhance low light performance and broaden the dynamic range up to a maximum of 105 dB. The DR-Pix™ technology pixel provides two modes. One, is a low conversion gain mode optimized to offer greater charge handling capacity in bright environments. Two, is a high conversion gain mode that delivers increased sensitivity and reduced readout noise in low light environments. Additional features include global reset release shutter mode, sophisticated on-board statistics engine, high-speed configurable context switching, automatic black level calibration (BLC), on-chip phase-locked loop (PLL) and temperature sensor.
