This function initiates the capture process.

When that has finished, the image will be present in memory, in device-independent bitmap DIB format. The function takes two integer parameters; in most cases these will both be zero. It returns a handle to the image. This displays a continuous feed of the image. At any time, the user can click on the Capture button to take the photograph.
