Abstract

PURPOSE:To improve the convenience of operation by providing a switch selecting a control signal of a character generator at recording and at reproduction and inserting a title character even at reproduction. CONSTITUTION:A switch 5 is thrown to the position of a recording character adder circuit 2 at recording, then a control signal from a character generator 4 is added to a signal inputted from a video signal input terminal 1 and the result is outputted to a video signal output terminal via a recording signal circuit 6 and the switch 3. On the other hand, since the switch 5 is thrown to the position of a reproduction character adder circuit 9 at reproduction, the character generator 4 controls the reproduction character adder circuit 9 to add the character to the video signal reproduced from a reproduction signal processing circuit 8 and the result is outputted to the video signal output terminal via the switch 3. Thus, even when no character is recorded at the pickup of the video camera, a title character is inserted without haste in the case of edit of a tape later and the convenience of operation is improved.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ＶＴＲ一体形カメラにおけるタイトル文字の
制御方法に関し、特に再生時にもタイトル文字を挿入す

る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling title characters in a VTR-integrated camera, and more particularly to a simple character generator that can insert title characters even during playback.

〔従来の技術〕[Conventional technology]

従来のＶＴＲ一体形カメラにおいては、キャラクタ−ジ
ェネレーターによって発生したタイトル文字を一旦記憶
しておき、録画時に、撮影シーンと一緒にこのタイトル
文字をテープへ記録する様になっていた。In conventional VTR-integrated cameras, the title characters generated by a character generator are temporarily stored, and the title characters are recorded on the tape together with the photographed scene at the time of recording.

なお、この種の装置として例えば、キャノン社製Ｅ８０
取扱説明書「４７．タイトル機能」に記載のものがある
。An example of this type of device is E80 manufactured by Canon.
There is a description in the instruction manual "47. Title function".

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上記従来技術は、再生時におけるタイトル文字の挿入ま
では考慮されておらず、テープ編集時等の再生時にタイ
トル文字を入れたい場合にタイトル文字を入れることは
できなかった。The above-mentioned prior art does not take into consideration the insertion of title characters during playback, and it is not possible to insert title characters when it is desired to insert title characters during playback, such as when editing a tape.

本発明の目的は、再生時にもタイトル文字を挿入するこ
とのできる簡易キャラクタ−ジェネレーターを提供する
ことにある。An object of the present invention is to provide a simple character generator that can insert title characters even during playback.

〔課題を解決するための手段〕[Means to solve the problem]

回路を設け、記録時と再生時に、それぞれタイトル文字
を挿入できる様にしたものである。In order to achieve the above object, the present invention provides a switch for switching the control output signal of the character generator between recording and reproduction, a recorded character addition circuit, and a reproduction character addition circuit. This allows you to insert title characters.

独立にタイトル文字を挿入できる。The switch for changing the output of the character generator is switched during recording and playback, and operates to control the recorded character addition circuit during recording and to control the reproduced character addition circuit during playback. This allows title characters to be inserted independently during recording and playback.

〔実施例〕〔Example〕

以下、本発明の一実施例を図を用いて説明する。 An embodiment of the present invention will be described below with reference to the drawings.

される。The figure shows a block diagram of a simple character generator for a VTR-integrated camera according to the present invention. During recording, the control signal of the character generator 4 is connected to the video signal adding circuit 2 by the switch 5. Characters are added to the signal input from input terminal 1, and
The signal is outputted to the video signal output terminal via the recording signal circuit 6 and the switch 3. On the other hand, during playback, switch 5
is connected to the reproduced character addition circuit 9, the character generator 4 controls the reproduced character addition circuit 9, adds characters to the reproduced video signal by the reproduction signal processing circuit 8, and adds the characters to the reproduced video signal via the switch 3. The video signal is output to the video signal output terminal 7.

本実施例によれば、記録時にも、再生時にも、タイトル
文字を挿入できるという効果がある。According to this embodiment, title characters can be inserted both during recording and during playback.

〔発明の効果〕〔Effect of the invention〕

本発明によれば、再生時においてもタイトル文字を挿入
