摘要:
Parallel light rays are applied to a cylinder and true exit positions of the rays from the cylinder are measured, phantom exit positions for the incident rays are calculated by using a mathematical function representing a phantom refractive index profile, and the mathematical function is modified so as to minimize the sum of the squared differences between the true and phantom exit positions.

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.

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 section 221 obtains attributes. For respective chapters, the attributes are held by an attribute file 500. A condition searching section 223 searches the attributes for the respective chapters in accordance with a condition input from a condition inputting section 222. A thumbnail obtaining section 224 obtains thumbnails that match the search condition. An index displaying section 226 displays the obtained thumbnails. When a thumbnail is selected via an image selecting section 227, an image reproducing section 228 reproduces image data in accordance with link information extracted by a link-information extracting section 225.
摘要:
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.
摘要:
To perform update processing and the like of an index file relating to change of a hierarchical structure easily and rapidly.The index file is recorded in a recording medium 2 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.

摘要:
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.
摘要:
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.
摘要:
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.
