In the recent times, many computer vision supported e-learning applications have been constructed, to provide the participants with the automated and real-time camera control capabilities. In this paper, we describe a portable and single-PC based instructional video capture system, which incorporates a variety of computer vision techniques for its video directing and close-up region specification. We describe the technologies used, including the laser-pointer detections, instructor's lip tracking and individual teaching object recognition. As the same time, we also explain how we have achieved both low-cost and portability property in our design.
