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.

An information processing system includes: an imaging device including a first recording medium recording a content file, and a management information storage unit storing management information for managing the content file in the first recording medium; an information processing device including a second recording medium recording a predetermined content file; and a control unit controlling so as to detect difference information relating to the storage state of the content file recorded in the first recording medium, based on the results of comparing present management information stored in the management information storage unit, with past management information which has been recorded before the present management information and is management information of the point-in-time at which the content file in the first recording medium was saved to the second recording medium, and record, in the second recording medium, the content file in the first recording medium, based on the detected difference information.

Imaging device, information processing device, information processing system, recording control method thereof, and program for causing a computer to execute the method

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.

Disclosed herein is an image processing apparatus, including a representative face extraction unit configured to detect face images in an image frame that forms part of video image data, and select, from the detected face images, a face image to be used as index information. The representative face extraction unit is configured to calculate a score of each of the face images detected in the image frame based on characteristics of the face image, and select a detected face image whose score is high as an index-use face image.

Image processing apparatus, imaging apparatus, image processing method, and computer program

A recording apparatus includes a first recording control unit configured to control recording of first management information so that fragments of the first management information and fragments of data are alternately placed, each fragment of the first management information being used to read the corresponding data fragment; a second recording control unit configured to control recording of second management information after all of the data has been recorded, the second management information being used to read all of the data; and a rewrite control unit configured to control rewrite of the first management information or the data after all of the data has been recorded so that any fragment of the first management information is not used to read the corresponding data fragment.

Recording apparatus, recording method, program, recording medium, and data recording medium

An information recording apparatus recording contents on a recording medium and managing the contents by using a content management file includes a control unit that checks a recording state of the recording medium loaded in the information recording apparatus to determine how to set up the content management file to be recorded on the recording medium and recording means for recording the content management file on the recording medium. The control unit determines the file setup of the content management file on the basis of the recording capacity of an area where the contents can be recorded on the recording medium. The recording means records the content management file in accordance with the file setup on the recording medium.

Information recording apparatus and information recording method

The present invention provides a file management apparatus for managing files, recorded on a recording medium, on the basis of an index file including management information about the files, the apparatus including: a management status information holding unit for holding management status information indicative of a management status of the files in the index file; a recording status detecting unit for detecting a recording status of the files recorded on the recording medium; and an inconsistency detecting unit for detecting an inconsistency between the management status of the files in the index file and the recording status of the files recorded on the recording medium on the basis of the management status information and the recording status detected by the recording status detecting unit.

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.

An electrical connector comprises a cover insulator and a base insulator relatively movable with respect to each other in a first direction. The base insulator has a plurality of conductive contacts assembled to extend in a second direction perpendicular to the first direction. The cover insulator has a plurality of pin insertion holes in one-to-one correspondence to the contacts. A board has a plurality of conductive terminal pins to be inserted in the second direction into the pin insertion holes in one-to-one correspondence. Each contact has a pair of resilient contact pieces biased in a third direction perpendicular to the first and the second directions when the cover insulator is moved in the first direction. Each of the resilient contact pieces has a contacting portion to be contacted to or released from each of the terminal pins. The cover insulator is provided with a plurality of preload projections protruding from one surface thereof to preliminarily bias the resilient contact pieces until the terminal pins are moved to be received between the contacting portions. The terminal pin and the preload projection are in a positional relationship such that either one is located at a position corresponding to the contact and can be moved to another position where it is separated from the contact.
