CMOSIS, the world’s leading supplier of high-performance sensors and analog ICs (ams AG, Swiss stock exchange stock code: AMS), today launched the industry’s first global shutter CMOS image sensor CMV50000, which can provide 48M pixels The high resolution is more than twice that of the previous generation CMOSIS global shutter CMOS image sensor.


CMV50000 is a medium-format 48M pixel sensor made with a patented 8-transistor pixel structure, with a pixel size of 4.6µm and a resolution of 7920 x 6002. It has very low noise and can provide excellent electronic shutter efficiency. The global shutter operation means that images of fast-moving objects can be captured without distortion.


In the full resolution mode, the optical dynamic range can reach up to 64dB, and in the sub-sampling 4K mode, the optical dynamic range can reach up to 68dB. The sensor uses a sophisticated new on-chip noise reduction circuit such as dark level clamping, which can capture high-quality images in low-light environments.


The sensor runs at a speed of 30 frames/sec in the full resolution or vertical combined 4k mode, and the pixel depth is 12 bits. When the sub-sampling is 4k resolution, the speed can reach up to 60 frames/sec, which is very suitable for High-speed machine vision systems, as well as TV broadcasting and video cameras.


CMV50000 can meet the requirements of large field of view for factory automation applications, including automated optical inspection (AOI) systems and systems for inspecting the display conditions of mobile phones, tablets, laptops and TVs. The combination of high frame rate and high resolution has further improved the already high output rate in consumer product assembly plants.


High Dynamic Range (HDR) mode is supported by odd/even line double exposure operation. CMV50000 is expected to replace the high-pixel-count charge-coupled device (CCD) image sensor used in machine vision cameras and high-end security cameras. Compared with CCD sensor technology, CMOS image sensors are easier to integrate in camera design, have lower power consumption, and have a much higher frame rate.


WimWuyts, image sensor marketing manager of ams, said: "The launch of the 48M pixel CMV50000 gives camera manufacturers the opportunity to enjoy the design and operation advantages of CMOS image sensors, while also obtaining ultra-high resolution. It can only be achieved with a CCD sensor. The advanced noise reduction design of CMV50000, such as the dark level clamp circuit combined with its high optical dynamic range, can achieve excellent image quality at full operating speed, and does not require a multi-tap CCD image sensor The complex analog output matching device, therefore, it can also significantly reduce camera development time."
