Abstract

PURPOSE:To understand the access frequency of the picture information by totalizing the access frequency of each picture information to store it in a memory and then delivering these memory contents in a retrieval mode. CONSTITUTION:For registration of information, the retrieval code of the picture information is stored in a main memory MM13. When the information equivalent to one page is stored on an optical disk 19, the memory address is set opposite to its retrieval code and stored in the MM13. Then this stored retrieval data is supplied to a disk device 27. Therefore the retrieval code and the memory address are stored in areas 28a and 28b of a disk 28, respectively. In a retrieval mode the memory contents of areas 28a and 28b are read out through a read-out part 28b and stored in a title memory 18. Then a supplied retrieval code is compared with that of the memory 18. The access frequency corresponding to the retrieval code is read out of the memory 18 and displayed at a CRT device 24.

Image information and the like are output as a hard copy 26. Reference numeral 27 denotes a magnetic disk device that writes search data for original image information consisting of a search code entered through the keyboard 23 and a storage address on the optical disk 19 where the image information corresponding to this search code is stored. Part 28. is used to store each piece of image information on the magnetic disk 28, and
Part 28 continues to appear for each image information! The data is reproduced from the magnetic disk 28 using. Above magnetic disk 2
8 is a search code storage area 28m in which a search code for each piece of image information is stored, as shown in FIG.
The above search code is composed of a memory address storage area 28b in which a memory address for each search code is stored, and a memory address storage area 28b for each search code. 28
It consists of a storage start address C2 of storage addresses in bζ2. As shown in FIG. 5, the search address is the image storage sector on the optical disc 19 for the image information corresponding to the search code, the track number T-ADH as the head address of the image information, and the sector number S@ADR.

It consists of an image size S, an access frequency storage area a, and a deletion mark b.

Next, the operation in such a configuration will be explained. first,
To explain the registration (storage) of image information, the user selects and sets the registration mode using the keyboard 23 and inputs the search code for the image information to be registered. This (from the second, 0PU12
The validity of the input data is checked based on the predefined search code format l2, the number of digits, character type, etc. (cyclic redundancy check, C-0), and the search codes that have already been registered are checked. Checks are made to see if there is any duplicate registration, and if the search code is correct as a result of these checks, it is stored in the main memory 13C. Then, set the original on the two-dimensional scanning device 2o, and
The PU 12 is an optical disk device 22 and a two-dimensional scanning device 2.
Operate 0. The two-dimensional scanning device 20 performs two-dimensional (two-scanning) and photoelectric conversion of image information such as a set document. This photoelectrically converted line information is transferred to the page buffer 1.
4'. When this page buffer 14 (knee pages worth of image information is stored), the image information is stored in the display interface 17, and the image information is displayed on the OIT display device 24. If the image displayed on the ray device 24 is satisfactory, a record key (not shown) is turned on.

Then, 0PUZ2 performs the well-known MH (Modifier-Hoffman) conversion (
2, and the compressed line information is supplied to optical disk drive #22. As a result, the optical disk device 2
2 stores the supplied image information on the optical disk 19.

When the storage of this image information is completed, the 0PU 12 stores the storage address such as the track number where the image information is stored, the starting sector, and the length of the image in the main memory 13 in correspondence with the search code.

Next, the 0PU 12 supplies the search data stored in the main memory 13, ie, the search code, track number, image length, etc., to the magnetic disk device 27. As a result, the magnetic disk device 27 transfers the supplied search data to the writing section 2.
7a is used to store information on the magnetic disk 28ζ2. That is, the search code of the search data is stored in the search code storage area 28g on the magnetic disk 28, and the storage address is stored in the storage address storage area 28b on the magnetic disk 28.
l2 memorized. Thereafter, other image information is also stored on the optical disk 19 in the same manner.

On the other hand, a search for image information registered as described above will be explained. First, the keyboard 23 is used to set the search mode. At this time, the storage contents of the search code storage area 28a and the storage address issue area 28b on the magnetic disk 28 are read out by the continuous output section 28b and stored in the title memory 18.

The operator then enters a search code.

Then, the 0PU 12 sequentially compares and collates the search code with the search codes stored in the title memory 18, and sequentially checks whether the search code matches the input search code.

As a result of this check, if there is only one search code, the CPU
12 reads the search code and the access frequency corresponding to the search code from the title memory 18 and displays it on the ORT display device 24. At this time, 0PU12
sets the access frequency within the search title in the counter 29.

Then, based on the above display, the operator inserts a recording key (not shown). As a result, the 0PUI 2 reads out the track number and start sector number of the image clearing corresponding to the search code C2 from the title memory 18. Then, the 0PU 12 causes the optical disk device 22 to convert the track on the optical disk 19 corresponding to that track number. Then, the 0PU 12 supplies the image information (compressed information) from the optical disk device 22 to the compression/expansion circuit 15 for each scanning line, performs band expansion by MH inverse conversion C2, and transfers the original image information to the page buffer 14. Supply sequentially.

In this way, the image 1 for one page is created in the page buffer 14.
? Once all the information has been stored, the 0PU 12 displays the image information on the CRT display device 24 using the display interface 16, or causes the recording device 25 to issue a hard copy 26 of the image information. At this time, the 0PU 12 counts up the counter 29 and updates the access frequency in the title memory 18 corresponding to the search code with this count content, and also updates the access frequency storage area of the storage address storage area 28b in the magnetic disk 28I: The memory contents of a are updated once.

Further, as a result of the above search code check, if there are a plurality of matching search codes, the 0PU 12 reads out the matching search codes and the access frequencies corresponding to those search codes from the title memory 18 and displays them on the CRT display device 24. For example, as shown in FIG.
3 (Input the second selection and input the record key.

At this time, 0PU12 reads the access frequency corresponding to the selected search code from the title memory 18 and sets it in the counter 29 (2). Then, 0PUJ and ? are the track number and start sector number of the corresponding image information. is read from the title memory 18.

Then, the 0PU 12 causes the optical disc device 22 to reproduce the track on the optical disc 19 corresponding to that track number. Then, the CPU 12 supplies the image information (compressed information) from the optical disk device 22 to the compression/decompression circuit 15 for each scanning line (2), performs band expansion by MH inverse conversion, and sequentially transfers the original image information to the page buffer 14. In this way, when all of the image information for one reproduced page is stored in the page buffer 14, the 0PUf2 uses the display interface 16 to display the image information on the OIT display gray device 24 (or display it on the display interface 16). Alternatively, the recording device 25 issues a hard copy 26 of the image information. At this time, the 0PU 12 counts up the counter 29 and updates the access frequency in the title memory 18 corresponding to the search code 52 with this count. C2, the storage contents of the access frequency storage area a of the storage address storage area 28b on the magnetic disk 28 (2) are updated. Also, when searching for other search codes, C2 operates in the same manner as described above.

The above search operation is shown in FIG.
It is C2 so that there are two lines.

In addition, as mentioned above, ≦2 registered optical dinuks19
When editing from to the optical disk 19s, the number of accesses for each image information is used as the editing condition, and a search code (deletion mark 1r2j? in the storage address storage area 28h of the magnetic disk 28 corresponding to 2?
Area I) Store the two deletion marks. As a result, it becomes possible to re-edit only the image information that has been accessed more than the number of times specified by the editing condition (difference is 1/).

In the above embodiment, the access frequency is displayed together with the search code, but since the key for commanding access frequency display is provided, the search operation and the access frequency can be displayed separately. (Do one line (you can do two).

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to provide an image information storage and retrieval device that can know the access frequency of image information.
