Popis: When lecture scenes are videoed for the distant lecture, a camera-person usually controls a camera to take suitable shots; alternatively, the camera is static and captures the same location all the time. Both of them, however, have some defects. It is necessary to control a camera automatically. We are developing ACE (Automatic Camera control system for Education) with computer vision techniques. The early version of ACE captures the lecture focusing on the latest object written on the blackboard. When noting something written on it or thinking over them, however, students may not always want to watch the latest object. We designed a recording function of the scene captured by ACE before for one of the solutions of this problem.
