Detailed introduction of industrial cameras
Publication time:2017年11月06日 Click:order Browse times:

It is commonly known as industrial camera camera, compared to the traditional civil camera (camera), it has high image stability, high transmission capacity and high anti-interference ability, currently on the market of industrial camera is mostly based on CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) chip camera. CCD is the most commonly used image sensor in machine vision. It integrates photoelectric conversion, charge storage, charge transfer and signal reading, and is a typical solid imaging device. The prominent feature of CCD is that the charge is used as the signal, and unlike other devices, the signal is current or voltage. This kind of imaging device transfers charge packets by photoelectric conversion, then transfers and amplifies the output image signals under the action of driving pulses. A typical CCD camera consists of optical lens, timing and synchronous signal generator, vertical driver, analog / digital signal processing circuit. As a functional device, CCD has the advantages of no burn, no lag, low voltage, low power consumption compared with vacuum tube. The development of CMOS image sensor first appeared in the early 1970s, and in the early 90s, with the development of VLSI technology, CMOS image sensor developed rapidly. CMOS image sensor integrates photosensitive element array, image signal amplifier, signal reading circuit, analog to digital conversion circuit, image signal processor and controller into one chip, and also has the advantages of random access of local pixel programming. At present, CMOS image sensor has been widely used in high resolution and high speed applications because of its good integration, low power consumption, high speed transmission and wide dynamic range.
