OMNIVISION, a global developer of semiconductor solutions encompassing advanced digital imaging, analog, and touch & display technology, recently announced two novel CMOS global shutter (GS) image sensors tailored for machine vision applications.
OMNIVISION has established a new Machine Vision Unit, dedicated to creating innovative solutions for industrial automation, robotics, logistics barcode scanners, and intelligent transportation systems (ITS).
The latest GS sensors from OMNIVISION, according to the company, boast the industry’s smallest 2.2-micron (µm) backside-illuminated (BSI) pixel, ensuring high resolution within a compact design. These high-resolution, small-format GS sensors offer shutter efficiency, enabling the clear and precise capture of high-speed moving objects at elevated frame rates. They also exhibit high sensitivity, minimal noise, and enhanced NIR quantum efficiency (QE), leading to exceptional low-light performance.
In comparison to the previous generation, 2.5µm frontside-illuminated (FSI) GS sensors, the 2.2µm BSI GS sensors can achieve 1.08x sensitivity with an F2.0 lens and 2.16x sensitivity with an F1.4 lens. The newly introduced OG05B1B is a 5-megapixel (MP) resolution CMOS monochrome GS sensor with a 1/2.53-inch optical format (OF), while the OG01H1B is a 1.5MP resolution CMOS monochrome GS sensor with a 1/4.51-inch OF.
“We see a huge demand in the machine vision market for 3D cameras and CMOS image sensors,” said Michael Wu, Senior Vice President, Global Sales and Marketing, OMNIVISION. “With our strong technological backbone in Nyxel, BSI and GS technology, we bring great innovation to the industry. Our new Machine Vision Unit will focus on understanding our customers’ needs and product roadmaps and address them with novel vision solutions.”
Both image sensors incorporate OMNIVISION’s Nyxel near-infrared (NIR) technology, enhancing QE to 700-1050nm, thereby facilitating the capture of brighter images from extended distances. They also integrate PureCel Plus-S stacked-die architecture for superior image sensor performance, along with CSP™ package technology for minimal dimensions.
Key features of the OG05B1B GS image sensor include:
- 2592 x 1944 resolution (5MP)
- Rapid frame rate of 60fps
- High shutter efficiency of 106 dB
- Interface: 4-lane MIPI & DVP
- External trigger snapshot mode enabling back-end exposure control for enhanced accuracy
- Nyxel boosting QE from 700 to 1050nm, 58% QE @850nm
Key features of the OG01H1B GS image sensor include:
- 1440 x 1080 resolution (1.5MP)
- Swift frame rate of 120fps
- High shutter efficiency of 106 dB
- Interface: 4-lane MIPI & DVP
- External trigger snapshot mode enabling back-end exposure control for enhanced accuracy
- Nyxel boosting QE from 700 to 1050nm, 58% QE @850nm
