Abstract

PURPOSE:To make index recovery efficient by providing a picture data storing part with a picture associated information control part. CONSTITUTION:The picture associated information control part B is provided at the head of the picture data storing part 1, and the addresses of picture associated information a1, a2... are recorded in it. At the time of index recovery processing, at first, the picture associated information control part B is read, and the first picture associated information a1 is read, and an attribute necessitated for generating an index is extracted from the picture associated information a1, and is turned into a key word for retrieval. Next, the address in which the next picture associated information a2... is recorded is recognized from the picture associated information control part B, and the picture associated information a2... is read. The above-mentioned processing is repeated. Thus, the read of the free area of a picture data part and the discrimination between the free area and a picture associated area can be omitted, and the speed of the index recovery processing can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image data retrieval device, and particularly aims to improve the efficiency of index recovery in a medical image retrieval device that needs to manage a large amount of image data. related to what happened.

[Prior Art] FIG. 5 shows an overall view of a conventional image data retrieval device, FIG. 6 shows details of an image data storage unit, and FIG. 7 shows contents of image accompanying information. In the figure, 1 is an image data storage unit, 2 is an image data management unit, 3 is a main controller, and the image data storage unit 1
contains a large number of image data A, , A2 . ．． ．． And each image data A1 ゜ A2, and the information AT with images that are each paired.

Areas A2-, , and free areas X+, X2, . . . are set.

Further, a conventional index recovery procedure is shown in FIG. Index recovery is a repair process when the image data management section 2 is destroyed. In the conventional index recovery process, first, the address of the first image accompanying information a1 is known (step 1), and the first image accompanying information a1 is found.
Attribute m+ required for index recovery from 1.

m2. , , is read (step 2), an index is created (step 3), and if the processing is not completed, the image data size n in the image accompanying information a1 is recognized and that portion is read quickly (step 5), Necessary attributes m, m2, . . . in the next image accompanying information a2 are read (step 6).

At this time, there is generally a margin between certain image data, such as image data 80, and the next image accompanying information, such as image accompanying information a2, to account for writing errors during data recording and for determining boundaries. There is a free area with a regular capacity, for example, free area X. Therefore, image accompanying information a
l+a2. , is read and image data A is obtained.

After reading A2.2, continue reading the area and read the empty area X,, X2. ．． ．． Image accompanying information al, a2.
．． ．． Step 7) is repeated to determine if the area is the area of , and then proceed to the previous step to obtain all the image accompanying information al, a2 . ．．
．． It was necessary to read the index and complete the index recovery.

[Problems to be Solved by the Invention] In the index recovery process in the conventional image data search device described above, free areas Xr, X2 .
, , and the free space xl.

Is it X2? Image a) Additional information a8. a296. This has the disadvantage that it takes time to complete index recovery because it has to be repeated for each image.

[Means for Solving the Problems] The present invention provides an image data retrieval device comprising an image data storage section, an image data management section, and a main control device. The present invention is characterized in that the image data storage section includes an image ancillary information management section for improving index recovery efficiency that manages ancillary information.

[Example] Next, an example of the present invention will be described with reference to the drawings. In addition, in the following, parts that are common to the conventional one are given the same reference numerals and redundant explanations will be omitted.

14I is a graph diagram showing the arrangement in the image data storage section of an embodiment of the present invention, FIG. 2 is a graph diagram showing the contents of the image ancillary information management section, and FIG. 3 is an attribute of the image ancillary information. FIG. 5 is a block diagram showing how an index is created by converting the index.

As shown in FIG. 1, an image accompanying information management section B is provided at the beginning of the image data storage section 1. This image accompanying information management unit B contains image accompanying information al+a2. , address b
,,b2. b, , , are recorded.

During index recovery processing, first the image accompanying information management section B of the image data storage section 1 is read (step 1 in FIG. 4), and the first image accompanying information a1 is read (step 2).
. The attributes necessary for creating an index from the image accompanying information a1 are extracted as ml, m2, , , and are converted into search keywords in blocks la and lb in Fig. 3.
, , ), attributes ml, m2. ．． ．． Create each index (Step 3), and add the attribute ml to the image data management section 2.
, m2. ．． ．． Add it as an index. Next, the image accompanying information management unit B sends the next image accompanying information a2. ．． ．．
Recognizes the address where is written and displays the image accompanying information a,
The process of reading , , , is repeated. Then, it is determined that the image accompanying information for all images is read and the index creation has been completed, step 4), and the index recovery process is ended.

[Effects of the Invention] As explained above, the image data retrieval device according to the present invention adds an image ancillary information management section to the image data storage section, thereby reading the free space of the image data section and managing the free space and images. Delete the process of distinguishing it from the attached area,
This has the effect of increasing the speed of index recovery processing.
