CMV50000 features low noise, high frame rate, and high dynamic range; easy-to-design-with sensor excels in automated optical inspection systems, machine vision users and prosumer video applications

Premstaetten, Austria — CMOSIS a member of the ams AG (SIX: AMS) group, a leading provider of high-performance sensors and analog ICs, today launched the CMV50000, an industry first global shutter CMOS image sensor offering high resolution of 48Mpixels, more than twice the resolution of its previous generation CMOSIS global shutter CMOS image sensors.

The CMV50000 is a medium format 48Mpixels sensor with 7920 x 6002 4.6-µm sized pixels using the patented 8-transistor pixel architecture to offer low noise and excellent electronic shutter efficiency. Global shutter operation means, that images of fast-moving objects can be captured without distortion.

Its pixel offers 64dB optical dynamic range at full resolution and up to 68dB in subsampled 4k mode, and the imagers benefits from the implementation of sophisticated new, on-chip noise reduction circuitry such as black level clamping to enable it to capture high-quality images under low-light conditions.

Operating at a fast 30 frames/s with 12 bit pixel depth at full resolution or a binned 4k mode, and at up to 60 frames/s with pixel subsampling to 4k resolution, the sensor is suitable for use in high-speed machine-vision systems, as well as in TV broadcasting and video cameras.

The CMV50000 provides detailed views of a large surface area required in factory automation applications such as automated optical inspection (AOI) systems and systems for the inspection of displays of mobile phones, tablets, laptops and TVs. The combination of high frame rate and high resolution allows further increase of the already high throughput rates at consumer product assembly plants.

A High Dynamic Range (HDR) mode is supported by an odd/even row dual-exposure operation.

The CMV50000 is expected to replace high pixel-count charge-coupled device (CCD) image sensors used in machine-vision cameras and high-end security cameras. Compared to the older CCD sensor technology, CMOS image sensors are easier to integrate in camera designs, use less power, and can operate at much higher frame rates.

“The introduction of the 48Mpixel CMV50000 gives camera manufacturers the opportunity to enjoy the design and operating advantages of a CMOS image sensor while gaining the ultra-high resolution, which has previously only been available through the use of CCD sensors”, said Wim Wuyts, Marketing Manager for image sensors at ams.

“The CMV50000’s advanced noise-reduction features such as black level clamping combined with its high optical dynamic range, results in high picture quality at full operation speed without the need for complex analog output matching required for multi-tap CCD image sensors and therefore also decreases the camera development time significantly.”

The monochrome version of the CMV50000 is sampling now. The color version will be available for sampling by the end of 2016. Unit pricing is €3,450.
