Abstract: PURPOSE:To avoid trouble of an object having an oscillator by moving an optical axis of a video camera in a direction in which a signal difference is minimized based on a voice signal obtained from vertical and horizontal pairs of plural microphones each having directivity. CONSTITUTION:Microphones 101, 102 have a directivity respectively and they are fixed to a direction so that each direction axis is always symmetrical with respect to an optical axis of a video camera. Detectors 103, 104 output a voltage in response to the quantity of an output of each microphone and a difference device 105 discriminates the quantity of voice output obtained from the microphones 101, 102 and a motor controller 106 drives a motor 107 to the right or to the left based on the result of discrimination and stops the motor when each voice output is equal to each other. The motor 107 drives the optical axis of the video camera and the microphones 101, 102. Thus, it is not required for a person or an object being a pickup object to carry an oscillator.
