We know that a web camera system consists of a video camera plus software that runs on a personal computer to periodically upload an image from the camera to a web page. Software running on PC functions to periodically upload the captured video image to an Internet web page. The basic purpose of a web camera system is to post a reasonably live picture on a user-specified web page. Many webcam systems upload images on a periodic basis; for example, uploading an image once per hour. Using the Internet connection, the captured video information is transmitted from the personal computer of one user over the Internet to a personal computer of another user. Webcams typically include a lens, an image sensor, and some support electronics. Image sensors can be CMOS or CCD. CMOS image sensors, when compared to charge-coupled-device (CCD) arrays, provide a low cost imaging semiconductor solution for web cameras and other optical sensing devices.
