JPS6369062A - Reproducing device for still picture disk with sound - Google Patents

Abstract

PURPOSE:To prevent a picture from being cut at the time of the output of a sound by providing a control means to store sound information only into a memory and output the sound information from the memory while the picture is reproduced as needed. CONSTITUTION:By the instruction of the change of a reproducing picture, a control part 14 moves a track head, in which the sound information related to the designating picture is recorded, by a head moving means 13, reproduces the information and stores it into a sound information memory 12. Thereafter, the track head is moved in which the designating picture is recorded and the picture is continuously reproduced. By the request of a sound output, the information is outputted from the memory 12. When the repeating output is requested, the information is outputted from the memory 12 at each time. During the period, the reproducing picture information is continuously projected on the screen. Thus, the sound information and the picture information can be simultaneously and continuously reproduced on the screen, the relation of the picture and sound is cleared and the cutting of the picture can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reproduction device for a disc on which still image information and audio information are recorded in a mixed manner.

[Conventional technology]

FIG. 3 is a block diagram showing an example of a conventional still image disc playback device with audio.
13 is a head moving means, and 14 is a control section. FIG. 4 is a flowchart showing the control process of a conventional still image disc playback device with sound, in which 21 is a playback image change instruction process, 22 is a head movement and playback process, 24 is an audio output instruction process, and 2
5 is an audio output process.

Next, the operation will be explained according to FIG. Upon receiving the instruction to change the reproduced image, the control section 14 controls the head moving means 13.
The head is moved to the designated track and the image information of the track is continuously reproduced.

Furthermore, if there is a request for audio output related to the image,
The control unit 14 moves the head to the designated trunk by the head moving means 13, reproduces the audio information of the track, and then moves the head again to the previous image track to continue reproduction.

[Problem that the invention seeks to solve]

Conventional still image disc playback devices with audio are configured as described above, so when audio is being output, the image is not displayed on the screen, making it difficult to understand the relationship between the image and the sound, and making it difficult to repeatedly play back the sound. There was a drawback that the head had to be moved each time, and the image was interrupted each time.

This invention was made to solve the above-mentioned problems, and there is no need to interrupt the image when outputting audio, and there is no need to move the head to the audio information trunk each time when outputting audio repeatedly. The purpose of the present invention is to provide a still image disc playback device with audio.

[Means for solving problems]

The still image disc playback device with sound according to the present invention includes a memory for storing played back sound information, and when receiving an instruction to play back an image such as changing a playback image, first plays back the sound information trunk related to the image. After the audio information is stored in the memory, the instruction image is continuously reproduced, and if there is a request for audio output, the audio information is output from the memory while the image is being reproduced.

[Effect]

Since this invention has the above-mentioned memory for storing audio information and control means, image playback is not interrupted when audio is output, and playback with a clear relationship between images and audio is possible. , it also becomes easier to repeatedly output audio.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram of an embodiment of the present invention. In the figure, 1 is a head, 2 is a disk such as a still video floppy, and 3 is a disk drive device. Further, 11 is an image input/audio input switch, 12 is a memory for storing reproduced audio information, 13 is a head moving means, and 14 is a memory for storing reproduced audio information.
2 is a control section that controls each section according to the control process shown in FIG. 2, which will be described later.

FIG. 2 is a flowchart showing the control process in this embodiment; 21 is a reproduction image change instruction process;
2 is a head movement and reproduction process; 23 is a process for inputting reproduced audio information into the memory 12; 24 is an audio output instruction process; and 25 is an audio output process.

Next, the operation will be explained according to FIG. When receiving an instruction to change the reproduced image, the control unit 14 first moves the head using the head moving means 13 to a track where audio information related to the specified image is recorded, reproduces the information, and converts the reproduced information into audio information. The data is stored in the storage memory 12. after that,
The head is moved to the track where the specified image is recorded, and the image is continuously reproduced. And if there is a request for audio output,
Audio is output from the audio information storage memory 12. If there is a repeated request for audio output, the audio will be output from this memory each time. During this time, reproduced image information is continuously displayed on the screen.

In this embodiment, audio information and image information can be continuously reproduced on the screen at the same time, and the relationship between images and audio can be clarified.

In the above embodiment, the audio information is stored in the memory, read out and output, but in the process, A/D conversion and D/A conversion are performed, and the information is output to the memory. The clock may be different.

Further, although the number of image information associated with the audio information of one trunk is usually one trunk, there may be a plurality of image information.

〔Effect of the invention〕

As described above, according to the present invention, a memory is provided for storing reproduced audio information, and after first storing audio information related to a specified image in the memory during reproduction, the image is reproduced, and when an audio output request is made, Since the audio information is output from this memory, the image can continue to be played on the screen even when the audio is being output, and even when the audio is being played repeatedly, the image can be played as many times as desired without interruption. This has the effect of clarifying the relationship between voice and voice.
