48MP CMOS image sensor supports 8K resolution

Article By : CMOSIS

The CMV50000 is a 35mm format 48MP sensor with 7920 x 6002 4.6µm sized pixels using the patented 8-transistor pixel architecture.

CMOSIS, a member of the Ams AG group, has launched a global shutter CMOS image sensor offering high resolution of 48MPs, more than twice the resolution of its previous generation global shutter CMOS image sensors.

The CMV50000 is a 35mm format (36.43mm x 27.62 mm) 48MP sensor with 7920 x 6002 4.6µm 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, according to the company.

Its pixel offers 64dB optical dynamic range at full resolution and up to 68dB in binned 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 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 re-solution 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 monochrome version of the CMV50000 is sampling now. The colour version will be available for sampling by the end of 2016. Unit pricing is ₹2.55 lakh (€3,450).
