Omnivision has announced the launch of three CMOS global shutter (GS) image sensors for machine vision applications and its Machine Vision Unit, which will develop solutions for industrial automation, robotics, logistics barcode scanners and intelligent transportation systems (ITS). The new unit was created to meet increased demand for 3D cameras and CMOS image sensors in machine vision applications.

Delivering high shutter efficiency and low-light performance for vision-guided robotics, logistics barcodes, high-speed inspection and intelligent transportation systems, the new OG05B1B and OG01H1B GS sensors feature the industry’s smallest 2.2-micron (µm) backside-illuminated (BSI) pixel for high resolution in a compact design. Compared to the previous-generation 2.5-µm frontside-illuminated (FSI) GS sensors, the BSI GS sensors can achieve 1.08× sensitivity with an F2.0 lens and 2.16× sensitivity with an F1.4 lens.
The 9-MP OG09A GS sensor, with a one-inch optical format, is the company’s first large-format GS solution for factory automation and ITS. The large-pixel, 3.45-µm BSI stacked sensor provides low readout noise and claims the highest quantum efficiency (QE) in its class. Its high image quality makes it suitable for machine vision applications that require the ability to capture clear images of high-speed moving objects. The OG09A is available in color (OG09A10) and mono (OG09A1B) versions.

The OG05B1B is a 5-MP resolution (2592 × 1944) CMOS monochrome GS sensor in a 1/2.53-inch optical format (OF). The image sensor offers a fast frame rate of 60 frames per second (fps) and high shutter efficiency of 106 dB. It supports 4-lane MIPI and DVP interfaces and features an external trigger snapshot mode, enabling back-end exposure control for improved accuracy.
The OG01H1B is a 1.5-MP resolution (1440 × 1080) CMOS monochrome GS sensor in a 1/4.51-inch OF. The image sensor offers a frame rate of 120 fps and high shutter efficiency of 106 dB. Like the OG05B1B, it supports 4-lane MIPI and DVP interfaces and has an external trigger snapshot mode, enabling back-end exposure control for improved accuracy.

Both image sensors feature high sensitivity, low noise and enhanced near-infrared (NIR) QE for low-light performance. They leverage the company’s Nyxel NIR technology, which boosts QE to 700-1050 nm (58% QE @850 nm), enabling the capture of brighter images from farther away; PureCel Plus-S stacked-die architecture and CSP package technology for a small solution size.
Omnivision said the “GS sensors provide the highest shutter efficiency available on the market with the ability to capture high-speed moving objects clearly and accurately at high frame rates.”

Targeting high-speed machine vision requirements, the OG09A image sensor’s 3.45-µm pixel is based on the PureCel Plus-S stacked-die architecture and Nyxel NIR technology for clear images in low-light conditions. The image sensor also features the company’s Dual Conversion Gain high dynamic range (DCG HDR) technology that extends the image sensor’s dynamic range capabilities and reproduces artifact–free, low-noise images in challenging lighting conditions, the company said.

“With the OG09A GS sensor, digital industrial cameras can now feature HDR support, high frame rates and higher resolution with better shutter efficiency,” said Kelly Yan, senior product marketing manager, in a statement.
Key features of the OG09A GS image sensor include high shutter efficiency of 106 dB, 90% QE response, 76-dB dynamic range with DCG HDR and high frame rate of 60 fps at 12-bit (8 × 8 region of interest reduces data bandwidth at even higher frame rates). It features an external trigger mode, enabling backend exposure control for improved accuracy, and supports up to a 16-lane LVDS interface to 1.05 Gbits/s.
The OG05B1B, OG01H1B and OG09A image sensors are sampling now. Mass production of the OG05B1B and OG01H1B will follow this quarter. Omnivision is exhibiting at the Automate Show, Chicago, Illinois, May 6-9, at booth #4279.
