Abstract

PURPOSE:To retrieve the records based on the image information by storing this information in response to a key word at the lowest level of an index part. CONSTITUTION:A file 1 consists of a record memory area 11 and an index part 12 which stores an index to give the accesses to the records stored in the area 11. A data processor 2 includes a keyboard 21, a picture display device 22, an image display control part 23, and a record reading part 24. The image information stored in response to a key word at the lowest level of the part 12 is displayed for retrieval of records. When the discontinuation of a retrieving operation is instructed, the records are read out based on the position information added to the key word. Thus a desired record can be retrieved with use of the image information like a phase photo, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file device that can use image information as a search keyword.

[Conventional technology]

Conventionally, file devices have indexes in which coded search keywords form a hierarchical structure, and when searching for records, the index is searched by using the coded search keywords. .

[Problem to be solved by the invention]

Therefore, in the conventional file device described above, a target record cannot be retrieved unless the encoded search keyword is known in advance. Therefore, it is not possible to search for a desired record using image information such as a facial photograph.

[Failure to solve the problem]

The file device of this invention has the following means.

(a) At the lowest level, there is an index section in which keywords and image information are stored as pairs; (b) When an instruction is given to start a file search using image information, the lowest level of the index section is searched to store keywords and image information. (C) An image display control unit that sequentially displays image information stored in pairs on an image display device; A record reading unit that reads records from the storage device according to the position information added to the keyword.

[Effect]

The search is completed by displaying the image information stored in pairs with the keyword at the lowest level of the index section, and when an instruction to stop the search is given, records are read out according to the position information added to the keyword.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of the file device of the present invention.

Reference numeral 1 denotes an auxiliary storage device for storing files, and this file is composed of a record storage area 11 for storing records and an index section 12 for storing an index for accessing the records.

2 is a data processing device, which is composed of a keyboard 21, an image display device 22, an image display control section 23, and a record reading section 24.

The keyboard 21 is used by the operator to instruct the start and stop of searching for files in the auxiliary storage device 1 . The image display control unit 23 reads the image information stored in the lowest level of the index unit 12 in the file of the auxiliary storage device 1 based on the search start and search stop instructions from the keyboard 21, and displays the image information in the image display device 2.
2 to display the image information. The record reading unit 24 reads records according to the record position information added to the keyword stored at the lowest level of the index unit 12 corresponding to the image information displayed on the image display unit 22.

FIG. 2 is a file structure diagram showing the structure of files in the auxiliary storage device 1. As shown in FIG.

The index section 12 is composed of an upper index block B and a plurality of lower index blocks B1 to BN.

The lower block B1 is composed of a plurality of keys Y11"YIM, and each key Yll~YIM is associated with records R11~RIM and 1 stored in the record storage area 11.
It corresponds to 1:1. The key Yll is 11 for the keyword of the record R11, and the record position information P1 indicates where the record R11 is located in the record storage area 11.
1, and image information I corresponding to record R11
It is composed of three pieces of data: II. The same applies to other keys as above.

Furthermore, in the lower block B1, keys ytt~Y1
m is arranged in ascending order of the code values of the keywords Kll to K I M , with the keyword Kll being the minimum code and the keyword YIM being the maximum code. In addition,
The key YIM including the keyword K I M of the maximum code becomes a representative key representing this lower block B1.

Moreover, the above-mentioned contents are exactly the same for other lower blocks.

The upper block B includes positional information P1 to PM indicating the location of each lower block, and a key Y1 having 1mxKNm as a keyword of the representative key of the lower block.
~YN.

Next, the operation will be explained.

First, the operator instructs the image display control unit 23 from the keyboard 21 to start a search using image information.

The image display control section 23 displays the index section 1 in the file in the auxiliary storage device f1 based on instructions from the keyboard 21.
The minimum code keyword Xtt of the lower block B1 is searched via the key Y1 of the upper block B of No.2. Then, the image information January stored corresponding to this keyword Kll is read out and displayed on the image display device 22.

After the display, the above-described operations are repeated unless an instruction is given from the keyboard 21 to stop the search.

That is, the image display control unit 23 controls the lower block B.
12 to KIM are sequentially searched for the keyword 1, and the same operation is performed for the other lower blocks B2 to BN.

When the operator looks at the image display device 22 and sees the desired image displayed, the operator instructs the image display control section 23 from the keyboard 21 to stop the search.

Based on instructions from the keyboard 21, the image display control unit 23 displays the image information currently displayed on the image display device 22, for example, if this is IIM, the record position information PI is input from the key YIM having the image information IIM.
M is transferred to the record reading unit 24 and the record reading υ unit 24 is activated.

The activated record reading unit 24 reads the record RIM specified by the record position information PIM from the record storage area 11 and transfers it to the image display control unit 23, and also activates the image display control unit 23.

The activated image display control section 23 causes the image display device 22 to display the transferred record RIM. This completes the series of search operations.

〔Effect of the invention〕

As explained above, since image information is stored in pairs with keywords at the lowest level of the file device ID index section of the present invention, records can be searched using this image information, such as a face photo. It has the advantage of
