Windows 7 programming framework consolidates a staggering collection of gadgets and usefulness, including webcam programming.
2、Webcams are electronic cameras that are available for general public use. These cameras are typically installed at an angle and are capable of taking pictures or video. Most Windows 7 webcams come with special software that can allow the user to capture images or videos, organize the data, and even transmit the data over the Internet.

二、Connect Win7 Webcam to your Computer
