First, the image and audio file reproducing unit 23 obtains frame reproduction information from the image file (S31). At this time, the display time of one frame becomes "1 (frames) / frame reproduction information (frames / sec)".

In step S31, the display time of one frame, the number of video data for configuring one frame, and the number of audio data to be reproduced while displaying one frame of video data can be obtained from the frame reproduction information. The number of image data to be obtained is obtained by the image resolution of the LCD, and the number of audio data to be reproduced while the image data of one frame is displayed is obtained by multiplying the number of audio data to be reproduced in one second by the display time (sec) of one frame. can do. This is the basis for confirming whether or not the audio data and the image data are synchronized in step S35.

The video and audio file reproducing unit 23 acquires audio data from the audio file, reproduces the obtained audio data through the speaker or earphone 25 when the reproduction operation of the video and audio file starts, and reproduces the audio data. Increase the number (S32).

The video and audio file reproducing unit 23 checks whether the display time of one frame has been reached through the system timer (S33). If the display time of one frame has elapsed, the image and audio file reproducing unit 23 obtains one frame of image data from the image file and the LCD (26). And display the number of image data of one frame (S34).

In step S32, the image data of the frame corresponding to the reproduced audio data with the increased number of reproduced audio data and the increased number of reproduced image data in step S34 is displayed, that is, whether the audio data and the image data are normally synchronized (S35). ). If the image data of the frame corresponding to the reproduced audio data is not displayed, steps S34 and S35 are repeated to synchronize the audio and the image.

The video and audio file reproducing unit 23 compares the total number of audio data and the total number of audio data by comparing the total number of reproduced audio data with the total number of audio data after synchronizing the reproduction audio data with the reproduction image data. When the number of reproduced audio data is greater than or equal to the total number of audio data (S36), the synchronization operation of the audio file and the video file is terminated (S36).

On the other hand, if the comparison result of step S36 indicates that the number of reproduced audio data is smaller than the total number of audio data, the operation of synchronizing the audio file and the image file is continued while repeating steps S32 to S35.

As shown in FIG. 6, the synchronization of the number of audio data for playback and the number of video data for playback other than the system timer is caused by a mismatch between the audio data for playback and the video data for playback due to a system timer error of the multimedia information reproducing means 20.
