CMV50000 features low noise, high frame rate, and high dynamic range; the easy-to-design-with sensor is aimed at automated optical inspection systems, machine vision uses and ‘prosumer’ video applications
The CMV50000 is a medium format 48 Mpixels 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 means, that images of fast-moving objects can be captured without distortion.
Its pixel offers 64 dB optical dynamic range at full resolution and up to 68 dB in subsampled 4k mode, and the imagers employ on-chip noise-reduction circuitry such as black level clamping to enable capture of high quality images under low-light conditions.
Operating at a 30 frames/sec with 12 bit pixel depth at full resolution or a binned 4k mode, and at up to 60 frames/sec 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 ap-plications 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. CMOSIS intends the CMV50000 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; they yield high picture quality at full operation speed without the need for complex analogue output matching required for multi-tap CCD image sensors.
