Abstract

PURPOSE:To eliminate file design for image housing by adopting a standby coupling and composing file in the case of image retrieving system constitution. CONSTITUTION:Image housing files 3 and 4 has a retrieving key in each standby coupling and composing file, namely, in each sub file to be composed of plural records. A retrieving information file 1 incidentally has an index for other retrieval with a number as a main key. A position control file 2 defines a registering number as a key. Then, after the file 2 is retrieved by a retrieving information key, it is positioned again by the registering number. Then, images on an image file 3 or 4 are read by the physical standby coupling file of retrieving subject image data and the sub file in the coupling file. Thus, when the image data are retrieved, it is enough to designate the registering number, namely, a sub file name and the other retrieving key. Then, the file design for the image housing is eliminated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image data retrieval system.

[Conventional technology]

Conventionally, in image data retrieval systems that store image files on magnetic disks, files for storing image data are designed to have a file structure unique to each system.

[Problem to be solved by the invention]

When designing image storage files in the conventional image data retrieval system described above, the association with index information and address management of stored images are considered, and management information and recovery methods in the event of storage efficiency failure are considered as file design conditions. This has the disadvantage that the total number of designs increases and the recovery method in the event of a failure becomes complicated.

[Means to solve the problem]

The image data retrieval system of the present invention comprises: an image storage file that is composed of a data area storing image data and a directory area having an address that specifies a storage area, and is organized in a standby connection corresponding to files; The subfile name named by .

A location management file consisting of a registration number and file name identical to the sub-file name, and an index information file storing the registration number and search key are provided, and the image data can be searched using the registration number and search key. It is characterized by the following.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, which includes an index information file 1, a location management file 2, and two image storage files 3 and 4.

The image storage file 3.4 is a standby combined organization file, that is, a file having a search key for each subfile consisting of a plurality of records, and is formed on a magnetic disk.

The index information file 1 has a number as a primary key and other search items as well.

The location management file 2 uses the registration number as a key, and after being searched using the index information key, it is located again using the registration number, and the image data is searched using the physical standby combined file of the image data to be searched and the subfiles therein. It is possible to read images on storage files 3' and 4.

Here, the registration number and subfile name are set to be equal.

In the image storage file 3.4, physical addresses of subfiles are managed in a directory area whose details are shown in FIG.

As a result of the above configuration, it can be seen that when searching for image data, it is sufficient to specify the registration number, that is, the subfile name, and other search keys.

〔Effect of the invention〕

As explained above, the present invention employs a standby combined organization file in constructing an image search system, which eliminates the need for file design for image storage and is effective in reducing man-hours. Furthermore, since there is no need to incorporate recovery into the image search system in the event of a failure, there is an overall effect of reducing development man-hours.
