Note that the moving image data that has been reproduced is deleted from the moving image data temporary storage unit 608 as needed, and a storage area for acquiring and storing unreproduced moving image data is secured in the moving image data temporary storage unit 608. .
[0057]
Next, it is determined whether the reproduction of the moving image data has been completed (step S506). That is, it is determined whether or not unreproduced moving image data exists. If the moving image data has not been completed (NO in step S506), the process returns to step S502 to reproduce the moving image data not yet reproduced, acquires the moving image data (step S502), and temporarily stores (step S503). Screen display (step S505) is repeatedly executed. Then, when the reproduction of the moving image data is completed (YES in step S506), the process returns to step S501.
[0058]
On the other hand, in step S501, when there is no moving image reproduction operation (NO in step S501), it is determined whether the card detection unit 601 has detected removal of the card 110 (step S507). When the removal of the card 110 is not detected (NO in step S507), the process returns to step S501. On the other hand, if the removal of the card 110 is detected (YES in step S507), the user interface processing ends.
[0059]
Next, the details of the moving image data prefetch processing in step S705 in FIG. 5 will be described with reference to FIG.

FIG. 7 is a flowchart showing the details of the moving image data prefetch processing according to the first embodiment of the present invention.
[0061]
First, moving image information (moving image position information and name information) corresponding to the extracted moving image reproduction information is read (step S801). Next, it is determined whether the reading of the moving image information has been completed (step S802). That is, it is determined whether or not unread moving image information exists. If there is no unread moving image information (YES in step S802), the moving image data prefetching process ends.
[0062]
On the other hand, if there is unread moving image information (NO in step S802), moving image data corresponding to the moving image information is obtained by the moving image data obtaining unit 604 for a predetermined unit (step S803). Next, the obtained moving image data is temporarily stored in the moving image data temporary storage unit 608 (step S804).
[0063]
Next, it is determined whether storage of a predetermined amount (for example, 10 seconds) of moving image data has been completed (step S805). If the storage is not completed (NO in step S805), the acquisition of the moving image data for each predetermined unit is completed until the storage of the predetermined amount of moving image data in the moving image data temporary storage unit 608 is completed (step S803). The temporary storage (step S804) is repeated. When the storage of the predetermined amount of moving image data in the moving image data temporary storage unit 608 is completed (YES in step S805), the process returns to step S801, and the moving image information corresponding to the next moving image reproduction information is read out. Until the reading of all the moving image information is completed, the processing of steps S801 to S805 is repeated.
[0064]
As described above, according to the first embodiment, when the card 110 is inserted, the portable information terminal 100 uses the index printed on the card 110 based on the operation information stored on the card 110. A predetermined amount of moving image data corresponding to an image is acquired and stored in the moving image data temporary storage unit 608. As a result, immediately after detecting the user's operation on the actual index image, the corresponding moving image data can be obtained from the moving image data temporary storage unit 608 and played back, and the moving image with high responsiveness to the user's operation can be obtained.
