Low light imaging

ON Semi lli intro and video (MM)

While capturing a still image or a video clip on a bright, sunny day can be straightforward, the situation becomes much more complicated when lighting is uncontrolled. A street at night, an underground garage, a dark corner with little illumination – these are the type of situations where a standard image sensor may not be sufficient.

Fortunately, several different technologies are available which can enhance an image sensor’s ability to successfully capture an image under these types of challenging lighting. Specialized color filter arrays increase the amount of visible light available for capture, or enable capture of near-infrared light. Pixel designs can be modified to maximize the amount of light that can be captured by the image sensor, and advanced electron multiplication technology can enable detection under sub-lux illumination.

onsemi has implemented these technologies – and more – in a portfolio of image sensors designed for use in challenging lighting conditions. See how these advanced devices, available from Avnet Silica, can help solve your low-light imaging needs.

Technologies for low light image sensing

On Semi LLI Technology Table

Technology	Description	Details
RGB-IR	RGB-InfraRed is a different filter type where one green spot in the standard Bayer Color Filter Array (CFA) is substituted with a spot which admits the Near-Infrared (NIR) wavelength to reach the sensor.	Learn more
Clarity+	Clarity+ is an alternative filter where, in the standard Bayer Color Filter Array (CFA), the green spots are substituted with clear spots, allowing the entire visible spectrum to pass through.	Learn more
HDR	High-Dynamic Range is a technology more efficient for photo capturing than for video. To take an HDR photo, the sensor takes different shots of the same scene at different exposure times and then mixes the shots by selecting the best.	Learn more
BSI	Back-Side Illumination, as the definition suggests, is referring to the part of the sensor which is actually exposed to the light.	Learn more

On Semi LLI Market Security HTML

Security & surveillance

In security and surveillance applications, there is very often the need to monitor environments which could be either very bright or very dark. In such applications a sensor should have good performance in dark light conditions as well as a high dynamic range.

ON Semi lli Markets Medical HTML

Medical & scientific

Medical imaging applications often require wide dynamic range and high light sensitivity to enable capture of the subtlest details without the loss of valuable information. Scientific imaging also presents demanding imaging requirements, whether for research or analysis, with the finest details of an image needing to be faithfully preserved.

On Semi LLI Market Automotive HTML

Automotive

Advanced Driver Assistance Systems (ADAS) require sensors with higher functionality to meet the evolving standards for car safety. Automotive camera systems are performing more complex algorithms at higher vehicle speeds and in new, challenging lighting conditions. Detecting and recognizing road signs, people, moving objects, hazards in low light scenarios is critical for ADAS systems.
