(Camera (CAMERA), also known as a computer camera, computer eye it as a video input device, and in the past has been widely used in video conferencing, telemedicine and real-time monitoring. In recent years, with the development of Internet technology, the continuous improvement of the speed of the network, coupled with a mature and a large number of photographic imaging device technology used in the manufacturing of the camera, which makes it the price down to the level of ordinary people can afford. At the same time two years CAMERA widely used in mobile phone, so also promote further improvement of photographic imaging technology, such as 300,000 pixels, 130 Vientiane)
