Relative to the microphone array system, toward a location corresponding to the position specified by the image of the predetermined range in which the camera device is the image imaging to form a sound collection directivity of the sound, and sound collection audio data with high accuracy. The directivity control system 10, the signal processing unit 33, in response to designation of an arbitrary position from the user in the video data displayed on the screen of the display device 36, into the screen from the installation position of the microphone array system 2 It picked up toward the sound position corresponding to the position of the specified video data Te (8MAh, 8MAv) to derive. The signal processing section 33 forms a sound collection directivity of the sound data to the derived sound collection direction (8MAh, 8MAv).
