Abstract
Description
【発明の詳細な説明】 産業上の利用分野 本発明は、ビデオカメラに関するものである。[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to a video camera.
従来例の構成とその問題点
従来のビデオカメラはビューファインダＴＶＴＲの録画
再生画面を見ることができるが、テレビ放送画面を見る
ことはできなかった。Conventional configuration and its problems Conventional video cameras can view the recording and playback screen of the viewfinder TVTR, but cannot view the television broadcast screen.
発明の目的
本発明は、ビデオカメラのビューファインダを通してテ
レビ放送画面も見ることが出来るよう江したものである
。OBJECTS OF THE INVENTION The present invention is directed to the ability to view television broadcast screens through the viewfinder of a video camera.
発明の構成
そのために本発明は、チーーナー回路、音声映像分離回
路等を有するテレビチューナーをビデオカメラに対し着
脱自在とし、ビューファインダへの映像信号の切換がで
きるようにしだものである。Structure of the Invention For this purpose, the present invention is such that a television tuner having a tuner circuit, an audio/video separation circuit, etc. is detachably attached to a video camera, and a video signal can be switched to a viewfinder.
実施例の説明
以下本発明の一実施例を第１図〜第４図により説明する
。ｌはビューファインダ、２はビデオカメラ、３はビデ
オカメラ２に対し着脱自在のテレビチューナーである。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. 1 is a viewfinder, 2 is a video camera, and 3 is a television tuner that can be attached to and detached from the video camera 2.
この場合、ビデオカメラは第２図のように撮像出力端子
４．ＶＴＲ（図示せず）およびテレビチー−チー３等が
接続される端子５．および端子５側に制菌信号が加わっ
た際、これでもってオフになるスイッチ回路５ａからな
る。In this case, the video camera has an imaging output terminal 4. Terminal 5 to which a VTR (not shown), TV Qi-Chi 3, etc. are connected. and a switch circuit 5a which turns off when a sterilization signal is applied to the terminal 5 side.
また、テレビチューナー３は第３図のようにチーーチー
回路６．音声映像分離回路７．音声出力回路８．電源回

力端子１０とカメラ２の端子５とは、第４図のように結
合自在であって、両者を結合する際カメラ２とテレビチ
ー−す−３とは電気的２機械的に結合できるようになっ
ている。Also, the TV tuner 3 has a chi-chi circuit 6. as shown in FIG. Audio video separation circuit 7. Audio output circuit 8. Power supply circuit 9. and an output terminal 10. In this case, the output terminal 10 and the terminal 5 of the camera 2 can be freely connected as shown in FIG. It looks like this.
以上の構成において、ビデオカメラ２の端子５にＶＴＲ
が接続されれば、スイッチ回路５ａがオフとなり、ビュ
ーファインダ１ではＶＴＲへの録画内容、またＶＴＲの
再生画を見ることができる。In the above configuration, a VTR is connected to terminal 5 of video camera 2.
When the switch circuit 5a is connected, the switch circuit 5a is turned off, and the viewfinder 1 allows the user to view the contents recorded on the VTR and the reproduced image of the VTR.
今、ＶＴＲの代わりにカメラ２にテレビチー一ナ−３を
結合すればカメラ２のスイッチ回路６がオフになるため
にビューファインダ１はテレビチューナー３のモニタと
なる。Now, if a TV tuner 3 is connected to the camera 2 instead of a VTR, the switch circuit 6 of the camera 2 is turned off, and the viewfinder 1 becomes a monitor for the TV tuner 3.
なお、スイッチ回路６はカメラ側でオン、オフするよう
にしてもよい。また、電源回路９のうち特にバッテリは
テレビチューナー３とは別構成とし、ケーブルでもって
結合するタイプとしても、またはカメラ、テレビ、チュ
ーナーとの王者一体形式としてもよい。Note that the switch circuit 6 may be turned on and off on the camera side. Further, in the power supply circuit 9, the battery in particular may be configured separately from the television tuner 3, and may be of a type that is connected via a cable, or may be of a type that is integrated with the camera, television, and tuner.
発明の効果
本発明は上記のような構成であり、本発明によればビュ
ーファインダの有効活用がはかれ、テレビ放送画１岳を
見ることができるものである。Effects of the Invention The present invention has the above-mentioned configuration, and according to the present invention, the viewfinder can be used effectively, and it is possible to see a single television broadcast image.
