ON Semiconductor, driving energy efficiency innovations, has introduced its latest high performance CMOS image sensor targeted for use in advanced video security cameras. The AR0230CS image sensor is a 1/2.7 inch optical format device with 105 decibel (dB) dynamic range that combines industry leading low-light capabilities with superior near-infrared (NIR) performance.
For security camera makers looking to upgrade their current 720p IP camera designs, the AR0230CS offers high quality 1080p (1920 x 1088 resolution) video, from the 1/2.7 inch 2.1 megapixel (MP) CMOS sensor with integrated high dynamic range (HDR) support. This image sensor enables the capture of high-definition (HD) 1080p video data at a rate of 60 frames-per-second (fps). 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 colour reproduction. This complete HDR functionality ensures fast time to market for new HDR 1080p camera designs. Additionally, the AR0230CS 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: a low conversion gain mode that is optimised to offer greater charge handling capacity in bright environments and a high conversion gain mode which 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.
The operating temperature of the AR0230CS spans from -30 °C to +85 °C, and has both parallel and HiSPi interfaces.
“With demands for higher resolutions, the growth in professional and consumer 1080p security cameras has been tremendous and the 2.1 megapixel, 1/2.7 inch AR0230CS sensor is well positioned for this market,” said Alvin Wong, senior director of automotive and industrial CMOS imaging products, ON Semiconductor. “This sensor’s extensive dynamic range, superior low light performance and NIR sensitivity set it apart from other imaging solutions on the market.”
