Abstract: To easily edit dynamic image content suiting user's preferences in consideration of the geographical position. A trajectory information generation unit 230 generates trajectory information about a trajectory during imaging of dynamic image content based on position information, wherein the dynamic image content is associated with the position information and azimuth information. An editing point setting unit 260 sets a section of the dynamic image content on a time axis based on the generated trajectory information. For example, the section is set based on a comparison result of an imaging range of the trajectory identified by the generated trajectory information (imaging range identified by azimuth information) and a specific target area such as a landmark. A play list information generation unit 270 generates play list information about a playback of the dynamic image content based on the set section.

Abstract: On a recording medium, there are recorded content files and an index file. The index file is constituted by attribute information of the content files (title text data, thumbnail-image data or the like). In the case of changing (recording or deleting) the content file, the index file is updated after the change. A computer sets up, in a nonvolatile memory, status information indicative of being in a predetermined process stage, during the predetermined process stage from a start of changing the content file to a termination of updating the index file. The computer, at turning on power, determines the matching/mismatching between the content and index files recorded on the recording medium utilizing the status information, thus repairing the index file as required.

Abstract: A file managing apparatus is disclosed which is capable of restoring deleted files with ease. When a user gives an instruction to delete a file 6, a parent entry number for the file 6 is changed from “1” to “2” in a property list having the entry number 6 associated with the file 6. Because the parent entry number that is set for the value “2” points to the entry of a recycle bin, the file 6 is placed in a virtually deleted state. Any virtually deleted file is later restored easily through simple processing.

Abstract: The occurrence of fragments is suppressed in an index file that manages individual contents files recorded on a recording medium. On an optical disk 2, a contents file and an index file that manages each of the contents files are recorded. The index file is formed of attribute information of each of the contents files (including text data of a title, thumbnail image data and so on). When a predetermined contents file is recorded on the optical disk 2, a microcomputer 19 updates an index file so as to register this predetermined contents file in the index file. In this case, the microcomputer 19 secures a predetermined number of continuous slots in fixed length in the index file, and allocates attribute information of this predetermined contents file to the slots. For example, a predetermined number is set to the maximum number of the slots, or to the average number of the slots to be predicted for use in order to register the contents file.
