The read MIDI data is read by 78 and transferred to the MIDI data reproducing circuit 84. A MIDI message is reproduced based on the MIDI data transferred to the MIDI data reproduction circuit 84. The reproduced MIDI message is converted into a MIDI signal of a predetermined transfer format by the MIDI interface 86, and then MIDI-O
Output to UT terminal 87. The MIDI signal is transferred to the sound source device 18 via the connection line 502 connected to the MIDI-OUT terminal 87. When a MIDI signal is input to the sound source device 18, a stereo music signal representing, for example, classical music, corresponding to the MIDI message represented by this MIDI signal, is converted and generated based on the sound source data. The generated music signal is
The signals are output to the outputs 504L and 504R of the sound source device 18 and input respectively. The music signals are amplified by the amplifiers 20R and 20L, respectively, and the amplified music signals are amplified by the loudspeaker 22R.
And 22L, and classical music corresponding to the MIDI message is sequentially output.

Next, in step 714, the image data stored in the RAM 78 is read by the memory controller 78, and the read image data is transferred to the image data expansion circuit 80 via the connection line 610. It Image data expansion circuit
The image data input to 80 is decompressed, and the image data for display is reproduced. The reproduced image data is output to the output interface 82 via the connection line 614, added with a sync signal for display on the NTSC color monitor device, and converted into a composite video signal. The composite video signal generated by the conversion is output from the output interface 82.
Output to 500, forwarded to display 16 and display 16
The image represented by the composite video signal is displayed on the display screen. While this image is displayed, the music information corresponding to the MIDI data that was started to be played in step 712 continues to be played. In this case, the classical music is the loudspeaker 22.
The output from R and 22L continues.

Next, in step 716, if it is desired to display another image, for example, when the system controller 88 is notified of the operation information detected by the operation section 90, the process advances to step 708 to select the desired image. The image data is read out, and the processing from step 710 is continued.

Image and MI
Since the music represented by the DI data is reproduced in synchronization with each other, the image and the music can be reproduced with a simple system configuration. Especially, the image formed on the film is displayed, and the music as the background music flows to the displayed image with high sound quality. Therefore, for example, it is possible to effectively produce the appreciation of the photographic image taken by oneself. it can.

The optical disk 12 in the image reproducing system 10 has a ROM area 40 as an area for recording code data forming music information and a recordable area 42 as an area for recording image data forming image information. Since it has, the recording area of the image data is not significantly reduced, and since code data such as MIDI messages representing music information is recorded in the ROM area 40, a large amount of music information can be recorded. I can do it. Further, since this music information is recorded in the premastered area copied by, for example, a stamper, a large amount of optical discs in which this music information is recorded can be created quickly,
Therefore, the inexpensive optical disk 12 can be provided.
Further, in the ROM area 40 of the optical disc 12, a control program for reproducing the MIDI data is recorded together with the MIDI data representing the music data, so that the reproducing device for reproducing the MIDI data can be configured simply. it can.

In this embodiment, image data and MIDI
The control program for synchronizing and playing the data is the directory "SEQENCE" in the second program area 56.
However, the control information representing the information for associating the image data with the MIDI data may be stored in, for example, NVRAM or the like. May be stored in the non-volatile memory.

As described above, according to the image reproducing system and the optical disc of the present invention, when the music data, the image data and the control information recorded on the optical disc as the image recording medium are read and the image data is reproduced, Since the music data is reproduced based on the read control information, it is possible to reproduce and output the image represented by the image data and the music represented by the music data with a simple system configuration. This music data is recorded in a dedicated premastered area for reading the data that constitutes the optical disc, and the image data is
It is recorded in a writable area in which the data forming the optical disc can be written. Therefore, an optical disc on which music data and image data representing a desired image are recorded can be produced relatively inexpensively and quickly.

Further, in the pre-mastered area, music data in which information constituting music is defined as a predetermined code is recorded, so that PCM which digitizes actual music is recorded.
Compared to data, music data has a smaller amount of information, so that the data storage capacity in the writing area where image data is recorded is not significantly reduced, and a large amount of music data is recorded in the premastered area. Can be made. Therefore, it is possible to arbitrarily select music data corresponding to a desired reproduced image from a large amount of music data.
