Sensors Expo 2019: An image sensor family with near-infrared and low light technology

25 June 2019

Omnivision Technologies Inc. has introduced a family of four megapixel image sensors with Nyxel near-infrared (NIR) and ultra-low light (ULL) sensors.

The OS04A10 gives security cameras a greater zoom range and artificial intelligence surveillance systems better object identification and facial authentication accuracy. The Nyzel NIR technology allows for quantum efficiency of 60% at 850 nm and 40% at 940 nm, which OmniVision said is three to five times better than sensors without the technology.

The 940 nm NIR lighting cannot be detected by human eyes in dark indoor settings, while 850 nm light is for outdoor security cameras. Because 940 nm NIR light is undetectable in dark indoor settings, indoor security cameras can capture clear images without disturbing sleeping occupants and can be concealed from intruders.

The OS04A10 series can produce 4 MP and 1080 images for recording as well as integrated dual-conversion-gain technology for high dynamic range (HDR) performance with three-frame staged shutter for minimizing motion artifacts and enable an HDR of 120 dB.

Sensors Expo 2019 takes place at the San Jose Convention Center on June 26 and 27.
