CMOS Image Sensor Enables High-Speed Machine Vision

Now in mass production, the CMV50000 CMOS image sensor from ams features a 35mm-format 7920 x 6004 array of 4.6µm-sized pixels based on a patented eight-transistor pixel architecture, is a breakthrough in CMOS image sensor performance. It operates at a fast 30 frames/s with 12-bit pixel depth at full resolution or a binned 4K and 8K modes, and even faster – up to 60 frames/s – with pixel sub-sampling at 4K resolution.

 

This means the CMV50000 can provide the detailed views of a large surface area that are required in factory automation applications such as automated optical inspection (AOI) equipment and systems for the inspection of displays of mobile phones, tablets, laptops and TVs. The combination of high frame rate and high resolution enables manufacturers to increase their already high throughput rates at consumer product assembly plants.

SENSORS EXPO & CONFERENCE

Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

The low-noise ams pixel architecture offers excellent electronic shutter efficiency, and the global shutter operation produces distortion-free images of fast-moving objects. The sensor offers 64dB optical dynamic range at full resolution and up to 68dB in binned 4K mode. The image sensor benefits from the implementation of sophisticated new on-chip noise-reduction circuitry such as black-level clamping, enabling it to capture high-quality images in low-light conditions. For more details, a datasheet is available.
