Abstract

PURPOSE:To select and record a voice signal of a radio broadcast simultaneously during video recording by incorporating a radio tuner to the video camera main body. CONSTITUTION:A video camera main body 1 is provided with an ancillary microphone 3 to record an external voice signal and a radio tuner 2 receiving a radio broadcast and the recorded voice signal is selected by a changeover section 7. The selected voice signal is recorded by a voice recording section 8. Simultaneously, the voice signal is listened to externally by a monitor earphone 9. The radio tuner 2 consists of an antenna 4, a tuning section 5 and a channel selection section 6 such as a dial and selects a broadcast suitable for recording at the outside of the main body. Thus, the surrounding voice signal during video recording is inputted from the ancillary microphone 3 or the voice signal of the FM or AM radio broadcast is inputted from the built-in radio receiver and recorded selectively by the changeover section 7, then a monotonous voice signal is avoided and the recording is attained while hearing the voice signal during the recording.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio receiving tuner comprising an antenna, a tuning section and a tuning operation section as a device for receiving a radio broadcast in a video camera body capable of simultaneously recording and recording video and audio. The present invention relates to a video camera capable of simultaneously recording radio broadcasts by incorporating (hereinafter abbreviated as radio tuner).

[0002]

2. Description of the Related Art Conventionally, the following recording methods have been used for audio from video cameras. 1. Record the voice from the accompanying microphone. 2. When editing after recording, add audio by inputting from the audio input terminal. 3. Record the selected sound from the built-in sound source. As a conventional technique of this system, for example, as described in Japanese Patent Laid-Open No. 2-182085, there is one in which a voice IC memory in which voice is recorded is built in a video camera, and the voice is selectively reproduced and recorded at the time of recording.

[0003]

However, each of these conventional recording systems has the following problems. With method 1, the audio that can be recorded by the video camera was monotonous and lacked in fun. In the second method, it is complicated and troublesome to operate the editing device and input the voice after the recording. In the method of 3, since the voice of the voice IC memory mounted on the video camera is simultaneously recorded at the time of recording,
Since it is necessary to carry an IC memory such as a card,
It can be lost. Also, the voices that can be recorded are limited to those recorded in the memory. An object of the present invention is to provide a video camera capable of recording a sound source of radio broadcast with a simple structure.

[0004]

By incorporating a radio tuner into a conventional video camera body capable of simultaneously recording and recording video and audio, it is possible to select and simultaneously record audio of a radio broadcast.

[0005]

The video camera according to the present invention has a camera body,
It has a built-in radio tuner consisting of an antenna, a tuning unit and a tuning operation unit. When recording, the audio of radio broadcast can be selectively recorded at the same time, and can be recorded while listening to the audio with an earphone from the monitor terminal.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an embodiment of a voice processing circuit of the present invention. The video camera body 1 has a built-in microphone 3 for recording an external sound and a radio tuner 2 for receiving a radio broadcast, and the recording sound is selected by the switching unit 7. The selected voice is recorded by the voice recording unit 8. At the same time, the sound can be heard from the outside by the monitor earphone 9.

The radio tuner 2 is composed of an antenna 4, a tuning section 5 and a tuning operation section 6 such as a dial, and can select a broadcast suitable for recording from outside the main body. Even in the non-recording state, the radio broadcast can be heard by the earphones. In the configuration diagram, the antenna is made to circulate around the main body in order to obtain a reception gain. Although the recording sound can be switched, it is of course possible to record the sound from the incidental microphone and the sound from the radio in a mixed manner.

[0008]

As described above, according to the present invention, during video recording,
Surrounding voice can be input from the attached microphone, and FM or AM radio broadcast voice can be input from the built-in radio, and it can be selectively recorded at the switching unit, so the monotony of the voice disappears and it becomes fun. . Moreover, you can record while listening to the voice being recorded. As a result, after recording, it is not necessary to operate the editing device to input the voice, or even if it is necessary, since the radio is built in, the operation is easy and most of the trouble is eliminated. Since the radio tuner is built into the video camera body, it is easy to carry. In addition, various sound source devices that emit audio signals within the frequency band of radio broadcasting, such as wireless headphone stereo and wireless microphones, are commercially available, and the audio signals from these external sound source devices are also built into the video camera. The selected radio tuner allows selective reception. By using these together when recording with a video camera, the sound that can be recorded is input from not only the incidental microphone but also the radio broadcast or the external sound source device, and the abundance is further enhanced to improve the enjoyment of the recorded work.
