- the image reproduction system shown in FIG. 8 includes an input device 1, a data processing device 11, a storage device 13, a storage medium 12, and an output device 4.
- the fifth embodiment of the present invention includes an input device, a data processing device, a storage device, and an output device, as in the first to fourth embodiments of the present invention.
- a storage medium 12 in which a search program is recorded may be a magnetic disk, a semiconductor memory, a CD-ROM or other storage medium.
- the search program is read from the storage medium 12 to the data processing device 11, controls the operation of the data processing device 11, and the storage device 3, the storage device 6, the storage device 8, and the like in the first to fourth embodiments.
- a metadata storage unit 31 a content storage unit 32, a display effect storage unit 33, and a display order list storage unit 61 are generated in the storage device 13.
- the data processing generation device 11 is the same as the processing by the data processing device 2, the data processing device 5, the data processing device 7, and the data processing device 9 in the first to fourth embodiments under the control of the search program. Execute the process. [0094] According to the fifth embodiment, as in the first to fourth embodiments, it is possible to easily determine that the content has been switched.
- the present invention can be effectively applied to an image reproduction system, an image reproduction method, and an image reproduction program for reproducing a plurality of still images or moving images while switching them automatically or manually, and in particular, recorded on a recording medium. It can be applied to systems and programs that reproduce and display content. Specifically, it can be applied to playback and display of content stored in hard disk recorders, home servers, personal computers, mobile phones, DVDs, digital cameras, and the like. It can also be used to display digital television programs when switching channels, and to display content contained in recording media such as personal computers and mobile phones that have been accessed via a network such as the Internet. Is also applicable.
