PURPOSE:To automatically change an image pickup direction, viewing angle, and sound collecting direction in a real time corresponding to the movement of a speaker without fixing the position of the speaker, and to detect the direction of the speaker by using at least three microphones in order to suppress the increase of a cost. CONSTITUTION:A camera 1 and a high directivity sound collecting microphone are fixed to a stand 4 by a direction controller 3. Also, a speaker direction detecting part 5 which detects the direction of the speaker is fixed to the stand 4. Information obtained from the speaker direction detecting part 5 is supplied to a speaker position analyzing part 6, and the direction of the speaker is obtained. A system control part 7 controls a camera control part 8 in order to move the camera 1 and the high directivity sound collecting microphone 2 by the information searched by the speaker position analyzing part 6, and controls the movement of the direction controller 3 in order to set the direction of the camera 1 and the high directivity 2 sound collecting microphone 2. |
