止画像を同期して再生する静止画再生装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a still image reproducing device that synchronously reproduces audio and still images recorded on separate recording media.
［従来の技術］
近年、複数の静止画像が記録された記録媒体から静止画
像を再生する再生装置が提供されている。[Background Art] In recent years, there have been provided playback devices that play back still images from a recording medium on which a plurality of still images are recorded.

の為、静止画作製者の意図が充分に反映され難いという
欠点があった。又、従来、動画の再生時には音声の再生
が可能であるが、静止画の再生時には音声の再生が禁止
されるのが通常であった。In such playback devices, the still images to be played back are switched by externally designated by the user of the device, or automatically and sequentially at predetermined intervals. For this reason, there is a drawback that it is difficult to fully reflect the intention of the still image creator. Furthermore, in the past, while it was possible to play back audio when playing back a moving image, playing back audio was usually prohibited when playing back a still image.
そこで、静止画を記録している媒体（例えば、フロッピ
ーディスク）とは別の媒体（例えば、磁気テープ）に音
声を記録しておぎ、静止画の再生と同時に音声を再生す
ることにより、情報量の増大を図った静止画再生装置が
提案されている。Therefore, by recording audio on a medium (e.g., magnetic tape) that is different from the medium on which still images are recorded (e.g., a floppy disk), and playing back the audio at the same time as the still images, the amount of information can be increased. A still image reproducing device has been proposed that aims to increase the number of images.
