New OmniVision image sensor combines Ultra Low Ligt and Nyxel near-infrared technologies for industry’s best nighttime camera performance

New OmniVision image sensor combines Ultra Low Light and Nyxel near-infrared technologies for industry’s best nighttime camera performance.

Elevated ULL and NIR Performance, along with high resolution and low power consumption, enable remote surveillance security cameras with AI for accurate facial recognition in all lighting conditions – OmniVision Technologies,a developer of advanced digital imaging solutions, today announced the OS02C10, a 2.9-micron, 2-megapixel image sensor with breakthrough ultra-low-light (ULL) technology.

Combining ULL with OmniVision’s industry-leading Nyxel(tm) near-infrared (NIR) technology, the OS02C10 works equally well in all lighting conditions. It can detect incident light in both visible and NIR wavelengths and produce precise color and monochrome images for security applications.

Nxyel NIR technology infuses the OS02C10 with exceptional quantum efficiency (QE) of 60% at 850nm and 40% at 940nm, which is 2x to 4x better than competing devices. Such excellent QE enables the use of lower-power IR illumination in total darkness, resulting in an estimated 3x reduction in system-level power consumption. Additionally, 940nm NIR lighting cannot be detected by the human eye in dark indoor settings, while 850nm light is ideal for outdoor security cameras. The OS02C10’s ability to capture crisp, clear images using undetectable 940nm NIR light means that indoor security cameras will not disturb sleeping occupants, and can be easily concealed from intruders.

The amount of NIR light that a sensor requires to capture high-quality images can be quantified with a new metric called NIR SNR1, which takes into account the QE, pixel size and read noise. The OS02C10 achieves an SNR1850nm of 23nw/cm2 and an SNR1940nm of 31nw/cm2, which are 2x to 4x smaller numbers compared with the leading competitors’ sensors. For the designers of security cameras that operate in total darkness, this means they can reduce IR illumination to consume 2x to 4x less power compared to the competitors’ sensors, for the same environment and over the same image-detection range.

“Surveillance cameras with AI functionality need the highest possible resolution in all lighting conditions for accurate facial recognition,” said Brian Fang, business development director at OmniVision. “These next-generation, intelligent-sensing surveillance systems are being enabled by our new sensor’s top imaging performance, with industry-best detection capabilities under both extremely low visible light and infrared light in complete darkness.”

The OS02C10 has a superior low-noise design, achieving an SNR1 of 0.16 lux while producing high definition 1080p images. OmniVision’s proprietary dual-conversion-gain technology allows this sensor to achieve the industry’s best ULL performance, while the 3-frame staggered shutter minimizes motion artifacts and enables a high dynamic range (HDR) of 120 dB. Additionally, these technologies are easily upgradable to 2K and 4K resolution as security systems begin their transition to higher-quality displays.

The OS02C10 image sensor is available now in an extremely small package. For more information, product samples or a demonstration, please contact your OmniVision sales representative at sales@ovt.com.
