ON Semiconductor has recently introduced AR0521 CMOS image sensor, the first imaging product based on a 2.2 micrometer (µm) Back Side Illuminated (BSI) pixel technology platform. The sensor is targeted particularly for the security and surveillance applications.
Coming to the product details, the AR0521 is a small optical format 1/2.5-inch (7.13mm), 5 mp digital image sensor carrying an active pixel array of 2592 (H) x 1944 (V). It works in either linear or high dynamic range (HDR) modes with roller-shutter readout, and is equipped with sophisticated camera functions like binning, windowing, and both video and single frame modes.
Moving on, it also offers 8, 10, or 12-bit outputs and delivers excellent performance at 5MP 60 frames per second (fps) videos with a 1440p mode for 16:9 video. Besides, its low-light performance is enabled mainly due to the larger 2.2 µm BSI pixel offering high linear full well and lower noise than a smaller pixel.
Carrying an electronic rolling shutter, the device offers advanced line synchronization controls for multi-camera (stereo) support. It’s capability of producing extraordinarily clear, sharp images is enhanced by sophisticated digital processing functions such as integrated color and lens shading correction, digital gain, and dynamic defect correction.
The sensor consumes very less power while operating at full resolution of 60 fps at 10-bit output. It operates at the temperature range of -30 degree Celsius to +85 degree Celsius, thus allowing the device to be used outdoors even in harsh environments. It is suitable for multiple use cases in mid- to high-end security applications like panoramic security cameras, speed dome security cameras, long range security cameras, and birdseye security cameras.
