Modern society, the rapid development of computer technology, people's homes have some more demand - scanner. It is more harmonious family offers a new way for home entertainment. Before choosing Zhaoqing scanner barcode scanner, the first to know about scanning gun. Scanner as optical, mechanical, electronic, software applications and other technology closely integrated high-tech products Zhanjiang barcode scanner, keyboard and mouse following the third generation of major computer input device. Since the birth of scanner barcode scanner Qingyuan 1980s, has been the rapid development and wide application, drawings, graphics, and presentation materials can be entered into the most direct, photographs, film to various types of computers with a scanner, and then realization of these image information processing, management, use, storage or output. Scanner works: using photoelectric element converts the optical signal into an electrical signal is detected, then the signal processing by the analog to digital converter into a digital signal is transmitted to the computer. When one image is scanned when the light source image of the reflected light after passing through the converging lens to the scanning module, the scanning module converts the optical signal into an analog digital signal (i.e., the voltage, the intensity of light it receives related), also pointed out that as the number of gray degree. This time analog - digital conversion circuit converts the analog voltage to a digital signal, transmitted to the computer. Colors with three colors of RGB bits 8,10,12 quantify both the number of bits of the signal into the above-described image output. If there is a higher number of quantization bits, means that the image can have a richer level and depth, but the color range beyond recognition capabilities of the human eye, it can be resolved within the range for us, a higher median scanner scanned color convergence effect is smooth, able to see more picture detail.
