Understand machine vision CCD industrial camera in seconds

What is a CCD Industrial Camera? In fact, the CCD industrial camera is a video camera, compared with the traditional civilian camera (video camera), it has high image stability, high transmission capacity and high anti-interference ability. Next, Xinxiwang will introduce you to the knowledge of machine vision CCD industrial camera.

CCD industrial camera is currently the most commonly used image sensor for machine vision. It integrates photoelectric conversion, charge storage, charge transfer, and signal reading, and is a typical solid-state imaging device.

The outstanding feature of CCD industrial cameras is that they use electric charge as a signal, unlike other devices, which use current or voltage as a signal. This type of imaging device forms a charge pack through photoelectric conversion, and then transfers and amplifies the output image signal under the action of the driving pulse. A typical CCD industrial camera consists of an optical lens, a timing and synchronization signal generator, a vertical driver, and an analog/digital signal processing circuit. As a functional device, CCD industrial camera has the advantages of no burn, no hysteresis, low voltage operation, and low power consumption compared with vacuum tubes. The development of CMOS image sensors appeared as early as the early 70s of the 20th century, and in the early 90s, with the development of VLSI manufacturing process technology, CMOS image sensors have 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 on a single chip, and also has the advantage of programming random access of local pixels.
