CCD

CCD is the core component of the scanner. CCD is called a photoelectric coupling device. It can output different currents according to the intensity of the irradiated light to complete the photoelectric conversion process. The scanner generally uses a linear CCD. Each line of the linear CCD is generally composed of 3000 to 10000 light detection points, and there are three lines of R, G, and B. The more light detection points in a certain unit length, the higher the opti...
