The magnetic disk device 27 stores various control programs on a magnetic disk 28 attached to the magnetic disk device 27, and also has an optical disk 20 that stores search information input from the keyboard 23 and images corresponding to this search information. It stores search data consisting of the above storage address, image size, etc.

The change in the storage location of the original image and the previous and previous images (old images) in the display memory 42 will be explained using the configuration diagram of the main parts shown in FIG. That is, the original processed image retrieved and read from the optical disc 20 is first stored in the page memory 40.

Before outputting the image in the page memory 40 to the display memory 42, the CPU 34 instructs the display control unit 4 to copy the image.
Output to 4. Then, the display control unit 44 uses the address control circuit 44a to designate the subsequent address and the write address, thereby saving the previous search contents stored in the storage area 42b from Memory to Mem.

The image (the latest image: the image currently being processed) supplied from the enlargement/reduction circuit 46 is stored in a (corresponding to ■ in FIG. 1).

As a result, the display control unit 44 changes the storage contents of the storage areas 42 a % 42 b % 42 c of the display memory 42 into the display area aS of the CRT display device 24, respectively.
Displayed as b and c.

As a result, the currently searched image is displayed in display area a, and the images searched last time and the time before last are displayed in display areas b and c, respectively, reduced to 1/2.

Next, the operation of image storage and retrieval processing in the electronic filing device with such a configuration will be described. First, image storage processing will be explained. For example, the user selects and sets the registration mode using the keyboard 23 and inputs search information for images to be stored on the optical disc 20. This search information is composed of a plurality of search keys, and the contents of the search key items are set in advance. The CPU 34 checks the validity of the input search information according to a predefined format.

Further, the search information is compared with the search information already registered on the optical disc 20 to check for double registration. Depending on the result of this check, the input search information is stored in the main memory 13.
is memorized.

Next, the original is set on the scanner device 18, and the CPU 34
operates the optical disk device 22 and scanner device 18. The scanner device 18 two-dimensionally scans and photoelectrically converts an image of a set document or the like. The line information of this photoelectrically converted image is sequentially stored in the page memory 40. The image stored in the page memory 40 is stored in the display memory 42 and displayed on the CRT display device 24. The user checks the skew, density, resolution, etc. of the image displayed on the CRT display device 24, and when the displayed image is satisfactory, inputs a memory key (not shown). Then, the CPU 34 compresses and expands the image stored in the page memory 40 for each line information.
ODEC) 50, the well-known MR (Modifier)
Encoding processing is performed by band compression using a method such as dRead). This encoded image is supplied to the optical disc device 22 and stored on the optical disc 20.

When the storage of the image on the optical disk 20 is completed, the CPU 34
stores the physical track address where the image is stored, the logical address determined from the physical sector address, the image length expressed by block length, image attributes, etc. in the main memory 38 in correspondence with the search code (search information). Then,
The CPU 34 supplies the search data stored in the main memory 38 to the magnetic disk device 27. Thereby, the magnetic disk device 27 stores the supplied search data in the magnetic disk 26.

Next, the search process for images stored on the optical disc 20 will be explained with reference to the flowchart shown in FIG. First, a search mode is set using the keyboard 23, and search information corresponding to the image desired to be searched is input. The CPU 34 sequentially compares and collates the input search information with the search information stored on the magnetic disk 26, and sequentially checks whether or not search information that matches the input search information is stored. Then, the CPU 34 reads out the logical address corresponding to the search information that matches the input search information. The CPU 34 calculates a physical track address and a physical sector address corresponding to this address, and uses these addresses to cause the optical disc device 22 to reproduce images from the optical disc 20. Also, CPU34
supplies the image (compressed information) for each scanning line supplied from the optical disk device 22 to the compression/expansion circuit 50, performs band expansion processing, and sequentially supplies it to the page memory 40. The image stored in the page memory 40 is reduced at a reduction rate of 80% by the enlargement/reduction circuit 46 and output to the display memory 42. As a result, the above-mentioned image is stored in the storage area 42a corresponding to the display area a of the display memory 42. Therefore, the display control unit 44 transfers the stored contents of the storage area 42a of the display memory 42 to the CRT display device 24.
Display in display area a.

Further, if a search has been performed before the above search is performed, the CPU 34 outputs an image copy instruction to the display control unit 44 before outputting the image from the page memory 40 to the display memory 42. Then, the display control unit 44 stores the previous search contents stored in the storage area 42b as a memory.
yt.

It is stored in the storage area 42c corresponding to the display area C using the Memory function. Next, CPU3
4, the previous search content stored in the storage area 42a is reduced to 172 by the enlargement/reduction circuit 46 and displayed in the display memory 42.
Output to. As a result, the previously searched image is reduced to 1/2 and stored in the storage area 42b corresponding to the display area b of the display memory 42. Next, the image stored in the page memory 40 is enlarged by an enlargement/reduction circuit 46.
The image is reduced at a reduction rate of 0%, displayed, and output to the memory 42. As a result, the latest image (the image currently being processed) is stored in the storage area 42a corresponding to the display area a of the display memory 42.

Therefore, the display control unit 44 records the contents of the storage areas 42a, 42b, and 42c of the display memory 42, respectively.
It is displayed in the display area aSbSC of the T-display device 24.

As a result, the currently searched image is displayed in display area a, and the images searched last time and the time before last are displayed reduced to 1/2 in display areas b and c. As a result, it is possible to understand what kind of searches have been performed, and the operability is good.

Also, the storage area 24b124c of the display memory 24
Writing images to the storage area 24a handles images in the display memory 24 (without using the page memory 40).
The page memory 40 is used when writing an image to the page memory 40. Therefore, as the page memory 40,
It can always handle A3.400ppi images.

Furthermore, when editing an image, etc., when an image is searched, a part of the searched image is extracted, and the image is rotated or enlarged, the same processing as described above is performed. As a result, the image currently being processed is displayed in display area a, and the previous image and the image before that are displayed in display areas b and c, respectively. As a result, it is possible to grasp what kind of editing processing has been performed, and the operability is good.

As mentioned above, when displaying on a single screen, images that have been processed (operated) in the past (previously and the time before last) are also displayed on the screen, so you can understand how the search or editing process was performed. It is easy to grasp the context of images, and has good operability.

Further, a rectangular display is used as the CRT display device, and when a vertically long image or a horizontally long image is displayed on the display, the gap can be effectively utilized.

In addition, in the embodiment described above, the case where the image displayed in the second display area is a reduced version of the image displayed in the first display area has been described, but the present invention is not limited to this. The image displayed in the area may be an enlarged version of the image displayed in the first display area.

[Effects of the Invention] As detailed above, according to the present invention, when the display means displays a single screen, it is possible to display the previously processed image in addition to the currently processed image, which improves operability. It is possible to provide an image processing device with good performance.
