Abstract

An annotation database section 232 of a hard disk drive 208 stores annotation data corresponding to each file separately from the file. The annotation data include attribute information, history information, and location information regarding each file. In response to input of desired conditions of an object file to be extracted, a data management module 226 reads out annotation data that meet the input conditions. An annotation information analyzer module 224 analyzes the syntax of the annotation data to gain location information. A data management module 226 obtains the object file from a location identified by the location information. Even when the object file is located at a remote place, for example, in a server on a network, this arrangement enables the object file to be readily extracted. The object file may be an image file or any other file.

Description

technical field [0001] The present invention relates to a technique for obtaining a desired file from among a plurality of files or displaying a history of the desired file. The present invention also relates to techniques for generating annotation information corresponding to image files. Background technique [0002] Due to the development of computer technology and network technology, in recent years, computers and networks have been filled with many files such as image files, voice files, official documents and program files. [0003] Therefore, it becomes a problem how the user obtains a desired file from among these many files. [0004] For example, a system described in JP-A-11-234605 is known as a system for searching such documents. [0005] This system is a system for retrieving image files such as photos. An image display device equipped with a magneto-optical disk retrieves images from many image files stored in the magneto-optical disk according to the combina...

Problems solved by technology

[0006] However, according to the above-mentioned prior art, since the image file is integrated with information on the shooting conditions and history of the image file, for example, when the image file is moved from the magneto-optical disk provided in the image display device to a remote location such as a network server, , because the image file is also moved together with the shooting conditions and history information, so there is a problem that the image display device can no longer acquire the image file

[0007] According to the prior art described above, since the files as objects are limited to image files, there is also a problem that other kinds of files such as voice files, text files, and program files cannot be obtained.

[0008] According to the above-mentioned prior art, since the information prepared for the image file is only the shooting conditions recorded at the time of shooting and the history information realized for the image file, even if the image content represented by the image file is used as a clue to obtain the desired image files, there is also the problem of not being able to obtain

[0009] Although such information can also be prepared by the user's text input, in this case, there is also a problem that the burden on the user is increased.
