Abstract

PURPOSE:To shorten the restoring time of a fault and to facilitate the management of image information by dividing the image information into plural files and thereby storing them. CONSTITUTION:An image management record 7 is read out of an image management file 6. The smallest image number 9 is compared with the largest image number 10 in an image information file included in the record 7. Then a fact whether the image numbers are kept between both numbers 9 and 10 or not. If so, a file name 8 of the image information file is saved. Then the image information 5 is read out of the image information file corresponding to the file name 8 with the number 10 defined as a key.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of managing image information, and more particularly to a method of managing image information in an auxiliary storage device of a computer.

[0002]

2. Description of the Related Art Conventionally, when managing image information by using an image number as a key item, the amount of image information data is enormous, and one index file must be used. Therefore, a large capacity file must be created. I won't.

[0003]

In the above-mentioned conventional image information management method, all the image information must be stored in one file, so that the file must be created over a plurality of auxiliary storage devices. Not
There is a problem that all information must be restored when a failure occurs. There is also a problem that it takes time to back up the medium and expand the file.

[0004]

According to a method of managing image information of the present invention, a plurality of image files having an image number as a key item and image information as items, a file name of this image file and the image file are stored. First, input the image number to be searched by using the image information file in which the record having the first and last image numbers as the items is the same number as the image file.
Step, the second step of reading the image management record from the image management file, the smallest smallest image number stored in the image information file and the largest largest stored in the image information file in the image management record. The image number is compared with the image number, and it is checked whether the image number falls within the range. If the image number does not fall within the range, the process returns to the second step. If the image number falls within the range, the file name of the image information file is saved. It is characterized in that the third step and the fourth step of reading the image information from the image information file corresponding to the file name of the image information file saved in the third step with the maximum image number as a key are executed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram of a file in an embodiment of the present invention. This file has a plurality of image information files 11, 12, ..., 1n each having an image number 4 as a key item and an image information record 3 having an image information 5 as an item and a file name of the image information file. 8, the smallest image number 9 stored in the image information file, and the largest image number 10 stored in the image information file, the image management record 7 having the items as the number of image information files. And an image management file 6 having the same number of records.

FIG. 1 is a flow chart showing the operation of an embodiment of the present invention. In step 21, the image number to be searched is input. In step 22, the image management record 7 is read from the image management file 6. In step 23, the smallest minimum image number 9 stored in the image information file and the largest largest image number 10 and image number stored in the image information file in the image management record 7 are compared to obtain the image. It is checked whether the number falls within the range, and if not, the process returns to step 22. If the image number falls within the range, the file name of the image information file 8
To evacuate. In step 24, the image information 5 is read from the image information file corresponding to the file name 8 of the image information file saved in step 23 by using the maximum image number 10 as a key.

[0008]

As described above, according to the present invention, an image management file for managing a plurality of image information files can be created to divide an image file into a plurality of image files. It is only necessary to restore the file, and it is possible to shorten the work time when expanding the file.

Claims (1)

[Claims] [Claim 1] A plurality of image files having an image number as a key item and image information as an item, the file name of this image file, and the first and last image numbers stored in the image file. Using an image information file that has as many image files as there are records that have items as items, the first step of inputting the image number to be searched, the second step of reading the image management record from the image management file, and the The smallest image number stored in the image information file is compared with the largest image number and image number stored in the image information file to check if the image number falls within the range. If not, return to the second step, If the image number falls within the range, the third step of saving the file name of the image information file, and the image information file corresponding to the file name of the image information file saved in the third step, using the maximum image number as a key And a fourth step of reading the image information, which is a method of managing the image information.
