Abstract

PURPOSE:To record narration at a position separated from a video camera by incorporating a narration mike in a remote controller. CONSTITUTION:The narration mike 12 is incorporated in the remote controller 10. Namely, the narration mike 12 converts voice to an electric signal, and outputs it to a transmitter 14. The transmitter 14 frequency-modulates a voice signal, and transmits it via an antenna 16. Meanwhile, a video camera 20 is provided with an antenna 21, a receiver 22, and a mixing circuit 23, etc. A signal sent from the remote controller 10 is inputted to the receiver 22 via the antenna 21, and an input signal is demodulated, and the voice signal is outputted to a recorder 25 via the mixing circuit 23. The recorder 25 includes an audio system signal processing circuit, and performs the magnetic recording of the signal on a video tape via an audio magnetic head after converting the signal to the one suitable for the magnetic recording. In such a manner, the narration can be recorded at the position separated from the video camera 20.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control with a built-in narration microphone, and more particularly to a remote control with a built-in narration microphone for remotely controlling a video camera.

[Conventional technology]

Traditionally, video cameras are equipped with a narration microphone in addition to a normal sound-collecting microphone.For example, by turning on the narration microphone switch and switching the microphone power, it is possible to record the narration in the desired recording. is now possible.

[Problem that the invention aims to solve]

However, when recording a narration while hand-held shooting, there is a problem in that camera shake is likely to occur during recording. Furthermore, some video cameras can be remotely controlled using a remote control, but the narration cannot be recorded from the position where the remote control is operated.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a remote control with a built-in narration microphone that can record a narration at a location remote from a video camera.

[Means for solving problems]

In order to achieve the above object, the present invention provides a remote control that transmits a remote control signal for remotely controlling a video camera.
The remote controller is characterized by comprising a narration microphone disposed on the remote control, and a transmitter that converts an audio signal manually inputted through the narration microphone into a predetermined transmission signal and transmits the signal to the video camera.

[Effect]

According to the present invention, when a voice is input manually through a narration microphone provided on a remote control, the voice is converted into a predetermined transmission signal by a transmitter and transmitted. and,
This transmission signal is received by the video camera and recorded along with the recording.

〔Example〕

Preferred embodiments of a remote controller with a built-in narration microphone according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a remote control with a built-in narration microphone and a video camera according to the present invention.

As shown in the figure, the remote control 10 with a built-in narration microphone includes a narration microphone 12, a transmitter 14, an antenna 16, an operation section 18, a microcomputer, and an electronic 7! (not shown), etc.

The operating section 18 includes a switch for instructing the video camera 20 to start/stop recording, and a predetermined signal is output from the microcomputer to the transmitter 14 in response to an operation on the operating section 18. The transmitter 14 performs FM modulation on the human input signal, for example, and outputs the modulated signal to the antenna 16, from which a remote control signal is transmitted.

Furthermore, the narration microphone 12 converts audio into an electrical signal and outputs this audio signal to the transmitter 14. Transmitter 14
FM modulates the audio signal and transmits it via the antenna 16 in the same manner as described above.

On the other hand, the video camera 20 is, for example, a camera-integrated VTR.
In addition to parts for normal functions, it includes an antenna 21, a receiver 22, a mixing circuit 23, etc. In the figure, 24 is a microphone, 25 is a recording device, and 26 is an electronic viewfinder.

The signal transmitted from the remote control 10 is transmitted to the antenna 21.
The signal is input manually to the receiver 22 via. The receiver 22 demodulates the human signal and outputs the audio signal to the recording device 25 via the mixing circuit 23. The recording device 25 includes an audio signal processing circuit, converts the signal into a signal suitable for magnetic recording, and then magnetically records the signal onto a video tape via an audio magnetic head.

Further, the remote control signal demodulated by the receiver 22 is outputted to a control section (not shown) of the video camera.

In this way, by using the remote controller 1O, the narration can be recorded at a location away from the video camera 20.

In the above embodiment, the mixing circuit 23 mixes the narration that is manually input via the receiver 22 and the audio that is manually input via the microphone 24 of the camera body. The microphone power may be switched by transmitting a remote control signal so that only the narration can be recorded.

FIG. 2 is a plan view showing another embodiment of the remote control with built-in narration microphone according to the present invention, and in this remote control with built-in narration microphone 30, the transmission medium of the remote control signal in the remote control IO shown in FIG. The difference is that it uses infrared radiation. In addition, in the figure, 31 is a narration microphone, 32 is a light emitting window, and 3
3 is an operation section.

FIG. 3 is a block diagram showing the internal configuration of the remote control 30 shown in FIG. 2. As shown in the figure, when an appropriate switch operation is performed on the operation unit 33, the microcomputer 34 outputs a signal in a predetermined format to the infrared light emitting diode 35 in accordance with the manual switch operation, and the infrared light emitting diode 35 outputs a manually operated electric signal. is converted into an optical signal, and an infrared remote control signal is transmitted via the light emitting window 32.

On the other hand, the narration microphone 31 converts the audio into an electrical signal, and outputs this audio signal to the optical modulator 37 via the amplifier 36. and transmits an infrared audio signal via this infrared light emitting diode 35.

The infrared signal transmitted as described above is received by a light receiver on the camera body side and demodulated. This allows the camera body to be remotely controlled, and narration to be recorded if necessary.

Note that infrared signals are directional, and depending on the direction of the remote control, the transmitted signal may not reach the user. Therefore, it is preferable to transmit the narration signal using radio waves as shown in Figure 1. good.

〔Effect of the invention〕

As described above, according to the narration microphone built-in remote control according to the present invention, since the narration microphone is built into the remote control and the narration signal is transmitted, the narration can be recorded at a location away from the video camera.

Additionally, since it uses a handheld remote control, it has the advantage of making it easier to record narration.
