CONSTITUTION:In the case of pickup of, e.g. a scene, a title picture signal is stored in advance in a video memory 8. When the title picture is desired to be superimposed on a pickup signal during the pickup of the scene, the title picture signal is read from the video memory 8 by the specified operation of the user. Then a video signal being a moving picture outputted from a camera processing circuit 4 and the title picture signal are added by an adder 5. An output video signal is fed to a video head 9 via a video processing circuit 6 and a recording amplifier 7 and recorded on a magnetic recording medium 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording and reproducing device that is capable of superimposing images such as titles.

Conventional technology] In the conventional magnetic recording/reproducing device, for example,
As described in Japanese Patent No. 72577, there is known a system in which a title captured by an image scanner is superimposed on the screen. However, in this prior art, only the image signal is superimposed, and in order to record the audio signal for this image signal, it is necessary to perform after-recording after recording and replace it with the desired audio signal. There was a problem in that it was extremely time consuming.

On the other hand, magnetic recording and reproducing devices are also known that are capable of superimposing audio, in order to create sound effects not only for images such as titles, but also for images such as superimposed titles ( For example, Japanese Patent Application Laid-Open No. 64-39879.

That is, a title picture memory is provided to store image signals such as titles, and a title sound memory is also provided to store audio signals of desired content, and image signals and audio signals are read from the title picture memory and title sound memory as necessary. , these are added to the video signal from the video camera and the audio signal from the microphone, respectively.

The image signal stored in the title picture memory is obtained from this video camera, and the audio signal stored in the title sound memory is obtained from this microphone.

In addition, in the above-mentioned conventional technology, a sound effect memory storing several sound effect signals is also provided, and any one of these sound effect signals is selected and read out, and the sound effect signal is converted into an audio signal from the microphone. It allows superimposition. As for the title picture, a character generator is also provided, so that the title picture created by this can also be superimposed on the video signal from the video camera.

[Problem to be solved by the invention]

However, in the above-mentioned conventional technology, the image to be superimposed is displayed in the viewfinder of the video camera, and the audio to be superimposed is heard through the video camera's speakers or earphones, and is not displayed in the viewfinder. The supplied video signal is similar to the video signal recorded on a magnetic recording medium, and
Since the audio signals supplied to speakers and earphones are similar to the audio signals recorded on magnetic recording media, it is not possible to check the image or audio to be superimposed while recording. Verification must be done before recording.

This becomes a particular problem when one of multiple types of titles is selected and superimposed, and one of multiple types of audio is selected and superimposed.

In other words, in the conventional technology described above, before shooting a scene, titles and audio that are considered optimal for the scene to be shot are selected, but after actually starting shooting the scene, the selected titles and audio are superimposed. Even if you pause, the audio may not match the shooting scene or title. In such a case, it is possible to reselect another preferable audio, but in order to confirm the selection 2, recording must be stopped, and if recording is interrupted, the necessary scene may not be recorded. (It becomes. Therefore,
Unless the recording of the scene is interrupted, the audio selected before shooting will have to be superimposed as it is, even if it is undesirable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic recording and reproducing apparatus that solves this problem and allows title images and audio to be arbitrarily selected, confirmed, and superimposed without interrupting recording.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a first storage means for storing a desired image signal, a second storage means for storing a desired audio signal, and a first storage means for storing a video signal of a moving image. The first . Second
and a third adding means for adding the desired audio signal read from the second storage means to the audio signal accompanying the video signal of the moving image. A fourth addition means is provided.

[Effect]

The video signal from the first addition means and the audio signal from the third addition means are recorded signals, and the video signal from the second addition means and the audio signal from the fourth addition means are supplied to the monitor. Ru.

This makes it possible to superimpose images and audio independently of the recorded video and audio signals and the video and audio signals provided to the monitor, allowing them to be monitored without affecting the recorded content. This allows you to check and select titles and audio.
