An information processing device, which includes: a data holding section which holds first time-series data of an operation parameter which varies through a predetermined capturing operation; a data comparing section which compares second time-series data of the operation parameter with the first time-series data, the second time-series data being correlated with a moving image recorded through an actual capturing operation and varying through the actual capturing operation; and a data area specifying section which specifies, among the second time-series data, a data area corresponding to the first time-series data on the basis of the comparison of the first and second time-series data.

Information processing device, information processing method and program

An information processing apparatus may generate resource information used for playing back image content that can be divided into a plurality of zones. The information processing apparatus may include an image generator generating a still image from each of the plurality of zones, a face processor setting each of the plurality of zones to be a target zone and determining whether a face of a specific character which is determined to continuously appear in at least one zone before the target zone is contained in the still image generated from the target zone, and an information generator specifying, on the basis of a determination result obtained for each of the plurality of zones by the face processor, at least one zone in which the face of the specific character continuously appears as a face zone, and generating information concerning the face zone as one item of the resource information.

Information processing apparatus and method, and program

An information processing apparatus may control display of a GUI image including indexes that allow a user to select the entirety or part of an image content piece. The information processing apparatus may include a controller configured to control display of a first GUI image including an index of each of at least one image content piece, and to control a display of a second GUI image including face thumbnail images, which serve as indexes that allow the user to select the entirety or part of an image content piece corresponding to an index selected from the first GUI image by the user, the face thumbnail images corresponding to faces detected from the entirety or part of the image content piece.

Update processing and the like of an index file relating to change of a hierarchical structure is performed. The index file is recorded in a recording medium with content files. The index file is generated based on attribute information of content files and folders including the content files. Content files and folders form a hierarchical structure in which the folders are in an upper hierarchy. In the index file, a prescribed number of entries (management information areas) corresponding to content files and folders, respectively, are provided. Second index information indicating second entries corresponding to folders or content files positioned in a lower hierarchy of folders in the upper hierarchy is provided at first entries corresponding to folders in the upper hierarchy in a list format. First index information indicating the first entries is provided at the second entries.

File processing apparatus, file processing method, program and recording medium

To search image information regarding image data, recorded on a storage medium, based on a desired search condition and to perform efficient display. An attribute-information obtaining sectionobtains attributes. For respective chapters, the attributes are held by an attribute file. A condition searching sectionsearches the attributes for the respective chapters in accordance with a condition input from a condition inputting section. A thumbnail obtaining sectionobtains thumbnails that match the search condition. An index displaying sectiondisplays the obtained thumbnails. When a thumbnail is selected via an image selecting section, an image reproducing sectionreproduces image data in accordance with link information extracted by a link-information extracting section

Image-information recording device and image-information display device

A recording apparatus such as an optical disk and a file management method are disclosed by which wastefulness caused by free slots in an index file can be reduced. To each slot of a property entry of the index file, valid/invalid information representative of whether the slot is valid or invalid is set. Further, to the header of the property entry, a last valid slot number indicative of a last one of those slots which are set to valid with the valid/invalid information is set.

The present invention is applied to reproduction of typically a fragment movie file having a QT format. In accordance with the present invention, management information associated with each block following a first block of the fragment movie file is modified to information compatible with management information associated with the first block and real data of the file is reproduced on the basis of the modified management information.

File reproduction apparatus, file reproduction method, file reproduction method program and recording medium for recording file reproduction method program

The present invention relates to a file management technique using indexes, wherein retrieval results and conditions for retrieval are recorded and stored on an entry for a virtual folder on the index for efficient later use. By this feature, objects for retrieval can be refined by using the recorded retrieval results, so that the processing for retrieval can substantially be simplified.

File management device

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, a parent entry number for the fileis changed from '1' to '2' in a property list having the entry numberassociated with the file. Because the parent entry number that is set for the value &#x201c;2&#x201d; points to the entry of a recycle bin, the fileis placed in a virtually deleted state. Any virtually deleted file is later restored easily through simple processing.

File management device, file management method, file management method program, and recording medium the file management method program

A recording apparatus such as an optical disk and a file management method are disclosed by which, where an index file is formed from groups of data wherein extract information is collected for different types and one of the groups of data is used to collectively manage the other groups of data, a process relating to deletion or addition of extract information can be executed simply, easily, and with certainty. In each of slots of a property entry, information representing whether the slot is valid or invalid and information representative of a relationship to different slots to which extract information relating to the same file is allocated are recorded, and a combination of the slots in which the extract information of the one file is allocated is managed with the property entry.

Before each content file is recorded first to a recording medium, a flag indicating a recording state of a content file is generated corresponding to a physical area where an index file can be continuously recorded. An index file is generated which associates attribute information with the generated flag added thereto with real data of each content file, and the generated index file is recorded to the recording medium. Since fragmentation of the physical area where the index file is recorded is restrained to a minimum level, a high-speed reading operation is realized.

Recording apparatus and method for generating an index file for a content file

A recording apparatus and a file management method are disclosed which can be applied typically to an optical disk apparatus and make it possible to grasp a hierarchical structure readily and register or delete extract information simply and easily. Reference information pointing to slots of a higher hierarchy, a lower hierarchy and the same hierarchy is set, and a flag is set to delete or register extract information without varying the reference information.
