PURPOSE: A lecture filming system using a sensor is provided to prevent the movement detection of students by detecting the movement of a lecturer from a down side using a sensor. CONSTITUTION: A sensing unit(10) includes a plurality of sensors(11). A sensing direction of each sensing sensor faces to the down side of a ceiling(43). A left and right rotatable camera films a platform area(40). A control unit receives the sensing result of the sensor. The control unit detects the location of a lecturer. The control unit matches the filming direction of camera with the detected location of the lecturer. |
