CMOSIS, a member of the ams AG group, has introduced the CMV50000, which the company says it considers to be the industry's first global shutter CMOS image sensor offering 48-megapixel resolution — more than twice that of CMOSIS' previous-generation global shutter CMOS image sensors.

The CMV50000 is a medium-format image sensor with 7920 x 6002 4.6-µm sized pixels using an 8-transistor pixel architecture to offer low noise and "excellent electronic shutter efficiency." Global shutter operation allows images of fast-moving objects to be captured without distortion.

CMOSIS' CMV50000 offers up to 8k video resolution.CMOSIS' CMV50000 offers up to 8k video resolution.The sensor's pixel architecture offers 64dB optical dynamic range at full resolution and up to 68dB in sub-sampled 4k mode. The company says that the imager benefits from the implementation of 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 30 frames per second (FPS) with 12-bit pixel depth at full resolution or a binned 4k mode, and at up to 60 FPS with pixel sub-sampling to 4k resolution, the sensor may be 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 as required in factory automation applications such as automated optical inspection (AOI) systems and systems for inspecting the 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 by the company to replace high pixel-count charge-coupled device (CCD) image sensors used in machine-vision cameras and high-end security cameras. Comparing CMOS image sensor technology to CCD technology, CMOSIS says that CMOS image sensors are easier to integrate in camera designs, use less power, and can operate at much higher frame rates.

The company also highlights the CMV50000’s noise-reduction features such as black-level clamping that — when combined with the imager's high optical dynamic range — results in high picture quality at full operation speed while avoiding the need for complex analog output matching required for multi-tap CCD image sensors.
