The "ThinkVantage Virtual Camera" or "Camera Plus (VGA Resolution Maximum)" is a pseudo camera device to expand camera experiences with features such as Face Focusing or Desktop sharing. It does not support HD resolution currently which limits the default camera resolution to VGA, even if the camera itself supports a higher resolution such as 1280x720.
Users have two cameras in their systems and can switch between "Integrated Camera" (High resolution) and "ThinkVantage Virtual Camera" (VGA resolution with additional features). The latter is chosen by default in many camera applications.
