DETAILED DESCRIPTION OF THE INVENTION The present invention uses an ordinary audio magnetic tape, an audio tape recorder, or a device of the same kind or similar thereto to reproduce audio information and image information, and to display images together with the pronunciation of the audio. The present invention relates to a device designed to do this.

Traditionally, video tape recorders and video disk devices have been used as image signal recording devices, but these devices record image signals as analog signals on magnetic tapes or disks, and are capable of recording detailed images as moving images in real time. It can be recorded with
It is unique in that it can be played back using a television display, and is used for recording image signals from television broadcasts and television cameras.

Unlike the above-mentioned video tape recorder and video disc device, the present invention uses a conventional audio magnetic tape, an audio tape recorder, or a device of the same type or similar as both the recording medium and the playback device to generate audio information and image information. The present invention provides a device that can simultaneously present the following information.

Note that since an audio tape recorder with a fixed head or the same or similar equipment is used, the amount of information that can be processed per unit time is limited, so graphics, characters, still images, animations, etc. Although it is mainly used for applications such as information, education, entertainment, etc., its applications are extremely wide. The present invention will be explained in detail below with reference to the drawings. FIG. 1 shows a schematic configuration diagram showing an embodiment of a recording device for recording audio information and image information presented in the present invention on a magnetic tape, and 1 in the figure shows an image signal formed by a television camera or the like. Input section, 2 is a control/processing section, 3 is an operation/control signal input section, 4 is an image memory section,
5 is a modulator, 6 is an audio signal input section consisting of a microphone or other acoustic device, etc., and 1 is a recording/reproducing device (or recorder), 8 and 9 are input terminals of the recording/reproducing device 7. FIG. 2 shows a schematic configuration diagram showing an embodiment of the present invention for reproducing and presenting audio information and image information recorded by the recording device shown in FIG. A recording/reproducing device (or reproducing device) consisting of a stereo audio tape recorder using a fixed head similar to 7, or a device of the same type or similar, 11 and 12 are output terminals of the recording/reproducing device 10, 13 is a demodulator, 14 is a control/processing unit;
15 is an operation input section, 16 is an image memory section, 17 is a display section using a television receiver or the like, and 18 is an audio signal output section composed of a speaker or the like. FIG. 3 shows an example of the recording format of a signal on a magnetic tape handled by the present invention. In the figure, 19 and 20 indicate stereo two-channel tracks, where 19 is the right channel and 20 is the left channel. ing. Further, 21, 22, and 23 indicate the types of recorded signals, 21 indicates control program data, 22 indicates image data, and 23 indicates a recording section for audio signals. FIG. 4 is a diagram showing an example of the configuration of the image memory unit 16 in FIG.
2, 44, and 46 are read control circuits.

Now, in FIG. 1, the image signal input section 1 is configured using a television camera and an analog-to-digital converter when inputting image information such as still images, animations, figures, etc., and encodes the image information. and supplies it to the control/processing section 2. In addition, image information such as text and simple shapes can be
Constructed using a figure generator to control and control digital image signals.
It is supplied to the processing section 2. The control/processing section 2 temporarily transfers the image signal (digital signal) from the image signal input section 1 to the image memory section 4 and stores it in order to match the recording speed of the audio tape recorder, that is, the recording/reproducing device 7.

That is, the image memory section 4 becomes a buffer memory. In addition, from the operation/control signal input section 3, a command signal (control signal in FIG. 1) for causing the control/processing section 14 of the playback device shown in FIG. - It is more rational to configure both the processing unit 2 and the control/processing unit 14 in FIG. 2 with a microprocessor as the main component, and the command signal in this case is a program).

Here, the control/processing section 2 outputs the command signal from the operation/control signal input section 3 and the image signal stored in the image memory section 4 at the recording speed (1200 to 9600 BP) of the recording/reproducing device 7.
As shown in the recording signal format of the track 19 in FIG. 3, the signals are first transferred to the control/processing unit 14 of the playback device in FIG.
A command signal (program data) is sent to the image memory section 4, and then an image signal (image data) stored in the image memory section 4 is read out and transferred. As a result, the command signal and the image signal become serial signals and are transferred to the modulator 5. This serial signal that has been transferred is sent to the modulator 5 in a number of hundreds to several tens.
It is modulated with a carrier wave signal of 0 Hz using a modulation method such as phase modulation, frequency modulation, or amplitude modulation, and this modulated signal is supplied to the input terminal 8 of the recording/reproducing device 7. If a conventional fixed-head stereo audio tape recorder, which is currently widely used, is used as the recording/playback device 7, the input terminal 8
, 9 are two recording input terminals for stereo recording, in which 8 is the right channel input terminal and 9 is the left channel input terminal.

The input terminal 8 of this recording/reproducing device 7 is supplied with the output signal from the modulator 5 as described above, but the input terminal 9 is supplied with the same means used for conventional audio recording, that is, a microphone or An audio signal is supplied from an audio signal input section 6 that inputs an audio signal from another audio device.

Incidentally, when the recording apparatus shown in FIG. 1 is assembled into the apparatus shown in FIG. 2, the recording/reproducing device 7 can be controlled by the control/processing section 14. With the above configuration, when a command signal and an image signal are supplied to the input terminal 8 of the recording/reproducing device 7, and an audio signal is supplied to the input terminal 9, and the recording/reproducing device 7 performs stereo recording on a magnetic tape, the result shown in FIG. As shown in tracks 19 and 20, command signals (program data) and image signals (image data) are recorded on the right channel track, and audio signals are recorded on the left channel track.

The timing of recording the command signal, image signal, and audio signal can be arbitrarily set depending on the type of display when they are played back. The timing can be set to record the accompaniment music of the poem as an audio signal, and when a still image or video is displayed, the narration of the commentary can be recorded at the same time.

FIG. 2 is a schematic configuration diagram of an embodiment of the present invention for reproducing a magnetic tape recorded by the recording device shown in FIG. It goes without saying that the same audio tape recorder can be used.

Now, the output terminals 11 and 12 are two stereo reproduction output terminals of the recording/reproducing device 10, with 11 being the right channel output terminal and 12 being the left channel output terminal.

As mentioned above, assuming that the command signal and the image signal are recorded on the right channel track of the magnetic tape, when the magnetic tape is played back by the recording/playback device 10, the output terminal 11
The serial signals of command and image signals are reproduced and extracted in a modulated state.

This signal is then demodulated by a demodulator 13 and converted into a digital command and image signal. The command and image signal from the demodulator 13 are supplied to the control/processing section 14,
The control/processing unit 14 has a microprocessor as its main component.
A RAM (Random Access Memory) that stores (programs) is configured with a controller that performs various controls and processes, and first, command signals are stored in the RAM that stores programs. The control/processing section 14 operates by sequentially executing the instructions stored in this RAM. Note that if only certain instructions are to be executed, it is also possible to use a ROM (read only memory). Next, when an image signal is supplied, the control/processing section 14 transfers the image signal to the image memory section 16 and stores it.

The image memory section 16 has a configuration as illustrated in FIG. 4.

In the figure, the full-screen memory 41 includes a readout control circuit 42.
is attached to the uppermost position of the display section screen under the control of the control/processing section 14 to control from which part of the entire screen memory the display starts. As a result, for example, if the position of the display part of the full screen memory 41 is moved one line at a time in accordance with the vertical synchronization signal of the display unit 17, the displayed image moves in the vertical direction, making it possible to scroll the display. . Furthermore, if the portions of the full screen memory 41 that are not displayed (for example, portions in the vertical synchronization period) are sequentially rewritten by the buffer memory 47, a long strip in the vertical direction will appear on the screen of the display section 17. It becomes possible to display images over time.

For example, when the audio information is music, a ``karaoke'' device that has both the so-called music and image display function, which displays lyrics, etc. on the display screen in time with the music being played, can be used with a normal audio cassette tape. It means that it can be realized by using. In addition, the read control circuit 44 in FIG.
, 46 is a control/processing unit 1 that determines in which position in the entire screen the screen memories 43 and 45 are displayed or not.
It is controlled by the control of 4. As a result, when attempting to display an action such as a person walking, the partial screen memories 43 and 45 alternately display the action pattern (for example, the up and down movements of the feet) from the buffer memory 47 in accordance with the vertical synchronization of the display unit 17. By sequentially displaying images (such as movement, etc.) and moving their positions using the readout control circuits 44 and 46, a pattern of a person walking within the screen can be displayed on the screen of the display unit 17. In other words, rewriting the screen memory at low speed,
With a small screen memory, a moving image can be displayed on the screen and audio information suitable for the moving image can be produced. This case can also be realized using a normal audio magnetic tape. Note that the data in the buffer memory 47 described above can be read sequentially from the magnetic tape, or all the data can be read first. Display section 1
7 uses the display section (video section) of the television receiver, but in order to display the image signal on the television screen,
The image memory unit 16 must be controlled in accordance with the timing of screen scanning, and signals must be read out and supplied to the display unit 17.

Such control and processing are also processed by the control/processing section 16.
In addition, in the case of characters or simple figures, a binary digital signal of 1 or O can be directly supplied to the display unit 17 for display, but in the case of still images or other images that require multiple gradations, control and
The processing unit 14 includes a digital-to-analog converter, converts the encoded signal into an analog signal, and displays the display unit 1.
Supply to 7.

Also, when supplying image signals to a television receiver,
Separates the image signal into red, blue, and green signals and supplies them to the input terminal of the primary color drive circuit of the television receiver's red, blue, and green signals,
A color image can be obtained by using a color display configuration. On the other hand, an audio signal is reproduced and taken out at the output terminal 12 of the recording/reproducing device 10.

This audio signal is supplied to an audio signal output section 18 comprising an audio signal amplifier, a speaker, etc., and outputs audio. It goes without saying that the audio circuit and speakers of the television receiver used in the display section 17 can be used as the audio signal output section 18. The operation input unit 15 is an operation input unit configured with a light pen, a keyboard, a tablet, etc. for interacting with the display image on the display unit 17, modifying the display image, and performing various other types of control and operation.

As explained in detail above, the present invention enables the use of a conventional stereo audio tape recorder, a conventional stereo audio tape recorder, a device of the same kind or a similar type thereof, and an image display unit such as a television receiver on a conventional audio magnetic tape. This allows scrolling images and video images to be displayed along with audio pronunciation. Note that as the audio tape recorder or a device of the same type or similar thereto, either a normal cassette type tape recorder or an open tape recorder can be used, but it is advantageous to use a set type because it is small and easy to operate. In this case, the tape speed is as low as 4.75CT1L/sec, but this does not pose any problem in the apparatus of the present invention. Furthermore, the present invention records audio signals, image signals, and command signals for the Mitaro computer on a cassette tape, and by replacing the cassette tape, the various functions described above can be easily changed and used in the same device. is possible.

Furthermore, both the image memory section 4 in FIG. 1 and the image memory section 16 in FIG. 2 can be constructed of a semiconductor memory or a magnetic bubble memory as a memory element.

Applications of the present invention include so-called karaoke, where accompaniment music is played while displaying poetry, picture stories and narrations similar to picture-story shows, language practice, displays in which various shapes change with music, and audio explanations such as cooking and childcare. There are many types of displays, various games, etc.

Furthermore, display in various colors is also possible.
