48MP Image Sensor Offers 8K Resolution In Machine Vision & Video Apps


CMOSIS has launched a high-resolution 48Mpixel CMOS image sensor with global shutter, which allows it to capture images of fast-moving objects without distortion.

The CMV50000 operates at a fast 30 frames/s supporting 8k image resolution, and at up to 60 frames/s in 4k mode, making it suitable for use in high-speed machine-vision systems, as well as in TV broadcasting and video cameras.

The sensor’s high resolution of 48Mpixels is said to be more than twice the resolution of the firm’s previous generation CMOSIS global shutter CMOS image sensors.

The 48MP sensor has 7920 x 6002 4.6-µm sized pixels and uses a patented 8-transistor pixel architecture to offer low noise and excellent electronic shutter efficiency, says the firm.

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.

In addiition, the CMV50000 can offer 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.

The new sensor 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 firm noted.

Low-noise Transistors For Noise Sensitive Circuit Design

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.
