<p>PROBLEM TO BE SOLVED: To prevent unpleasant noise at zoom lens drive from being recorded onto a magnetic tape by attenuating an audio signal in interlocking with the operation of the zoom lens controlling a field angle of an image formed onto a film. SOLUTION: A video camera section 3 reaches a recording state by an operation of a video camera operation section 6a. When the camera section 33 reaches the recording state, the attenuation of an audio control circuit 13a is maximized to record no audio signal onto a magnetic tape. The attenuation of the audio control circuit 13 is decreased in a prescribed time and the audio recording by the video camera section 3 restores to the normal state. In the case of the recording state of the video camera 3, when a zoom lens operation section 6c of an operation section 6 is operated, the attenuation of the audio control circuit 13a is maximized to record no audio signal onto the magnetic tape 2. Thus, unpleasant zoom lens operation noise is not recorded onto the magnetic tape 2. When a stop button of the operation section 6a is operated, the attenuation of the audio control circuit 13a is increased and the camera section 3 is stopped with the maximum attenuation.</p> |
