On the other hand, the scanner device 18 is, for example, a two-dimensional scanning device, which obtains an electric signal corresponding to an image of an original by two-dimensional scanning an original (document) image with a laser beam light. 18 and the like are sequentially stored in the optical disc 20, and the image corresponding to the search information designated by the keyboard 23 or the like is retrieved from the optical disc 20. FIG.

The keyboard 23 inputs unique search information corresponding to an image stored in the optical disk 20 and various operation commands such as memory, search, editing processing, and the like. The mouse 29 is, for example, a CRT display device 24. Display cursor (not shown) on the display window (24a) on the up and down, left and right to give an instruction at the desired position (various operation modes, area for editing image or Icon or the like).

The CRT display device 24 (cathode ray tube display device) is made of a rectangle that displays the image read out from the scanner device 18 and the image retrieved from the optical disc 20. The CRT display device 24 Icon is displayed on the top, bottom, and right ends of the display window 24a (a square or approximately forward display area), and the forward portion in the center of the screen is the entire display area A for displaying an image. In the case of displaying the vertical length image or the horizontal length image of the area A, the image displayed in one revolution and the image displayed in two revolutions are reduced to 1/2 in the blank area.

Therefore, if the original image is a vertical image, the old image (last image, the previous image) is reduced to 1/2 and displayed in two vertical lengths. If the original image is a horizontal image, 1/7 Zoom out to 2 and display it on two sides vertically. For example, as shown in FIG. 4 and FIG. 5, the original processing image is displayed in the display area a (first display area), and the spherical image (the previous or previous image) is respectively displayed in the display areas b and c; 2 display area).

In addition, the display area a of the CRT display device 24 is a multi-window display device capable of simultaneously displaying four images by using up to four windows (not shown). Each of the images displayed on the screen is independently subjected to editing processing such as enlargement, reduction, rotation, scrolling, and the like of the images.

The printer apparatus 25 prints and outputs the image read by the scanner apparatus 18 and the image retrieved from the optical disk 20 or the image displayed on the CRT display apparatus 24, and the magnetic disk apparatus ( The optical disc 20 stores various programs in the magnetic disc 26 mounted on the magnetic disc apparatus 27, and also stores the retrieval information input from the keyboard 23 and an image corresponding to the retrieval information. Is for storing the retrieval data consisting of the memory address, image size, and the like.

The change of the storage position of the original image and the previous or previous image (old image) in the display memory 42 will be described using the configuration diagram of the main part shown in FIG. The original processing image retrieved and read out from the optical disc 20 is first stored in the page memory 40, and before the image of the page memory 40 is output to the display memory 42, the CPU 34 copies the image. An instruction is outputted to the display control section 44. In this case, the display control section 44 designates the read address and the write address using the address control circuit 44a, thereby storing the information stored in the storage area 42b of the display memory. The contents of the previous search are stored in the storage area 42c corresponding to the display area c using the copy function (corresponding to Fig. 1).

Next, the CPU 34 specifies the read address using the address control circuit 44a of the display control unit 44 to output the entire search contents stored in the storage area 42a to the enlarged reduction circuit 46. The output image is reduced to 1/2 in the enlargement reduction circuit 46 and output to the display memory 42. At this time, the CPU 34 designates the write address by using the address control circuit 44a of the display control unit 44, so that the enlarged and reduced circuit is stored in the storage area 42b corresponding to the display area b of the display memory 42. The image supplied from 46 (the image obtained by retrieving the image searched last time by 1/2) is stored (corresponding to FIG. 1).

Next, the image stored in the page memory 40 is reduced to 80% reduction in the enlargement reduction circuit 46 and output to the display memory 42. At this time, the CPU 34 controls the address control circuit of the display control section 44 (the By specifying the write address using 44a, the image supplied from the enlargement / reduction circuit 46 to the storage area 42a corresponding to the display area a of the display memory 42 (the latest image: currently processed Image) is stored (corresponding to Fig. 3).

As a result, the stored contents of the storage areas 42a, 42b, 42c of the display memory 42 are displayed in the display areas a, b, c of the CRT display device 24, respectively. The image is displayed in the display area a at a reduction rate, and the image retrieved the previous time and the previous time is reduced to 2/1 in the display areas b and c, respectively.

Next, the operation of the image storage and retrieval processing in the electronic filing device will be described. First, the image storage processing will be described. For example, the keyboard 23 selects and sets the registration mode and inputs the search information of the image stored in the optical disk 20. The search information is composed of a plurality of search keys, The content will be set in advance. Thereafter, the CPU 34 checks the validity of the input search information according to a predefined format, and checks the double registration by comparing with the search information registered in the optical disc 20 in advance. The search information input in accordance with the inspection result is stored in the main memory 38.

Next, the original is placed in the scanner apparatus 18, and then the CPU 34 operates the optical disk apparatus 22 and the scanner apparatus 18. The scanner apparatus 18 two-dimensionally displays an image displayed on the set original. The image is scanned sequentially and photoelectrically converted into line information, and output. The line information of the output 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 then displayed on the CRT display device 24. By checking the skew, density, resolution, etc. of the image displayed on the CRT display device 24, When the displayed image can be satisfied, a memory key (not shown) is input. In this case, the CPU 34 compresses the image stored in the page memo 40 by band compression by a known MR (Modified Read) method or the like in the compression extension circuit 50 (CODEC) for each line information. This encoded image is supplied to the optical disk device 22 and stored in the optical disk 20. As shown in FIG.

When the recording of the image is finished on the optical disc 20, the CPU 34 retrieves the code for storing the image, the image length represented by the block length, the image length, the image attribute, and the like determined from the physical track access and the physical sector access. It is stored in the main memory 38 in correspondence with the (search information). Next, the CPU 34 supplies the search data stored in the main memory 38 to the magnetic disk device 27, and the magnetic disk device 27 stores the search data supplied in the magnetic disk 26. As shown in FIG.

Next, the retrieval process of the image stored in the optical disc 20 will be described with reference to the flowchart shown in FIG. First, the search mode is set by the keyboard 23, and search information corresponding to an unsearched image is input (T1). The CPU 34 then sequentially compares the input search information with the search information stored in the magnetic disk 26, and sequentially checks whether the search information matching the input search information is stored (T2). The logical address corresponding to the search information corresponding to the search information input by the 34 is read out, and the CPU 34 calculates the physical track address and the physical sector address corresponding to this address, and calculates the optical disk ( 20 reproduces the image from the optical disk device 22, and the CPU 34 compresses the image (compression information) for each scan line supplied from the optical disk device 22 into the compression extension circuit 50. ), Band extension processing is performed to sequentially supply to the page memory 40 (T3). The image stored in this page memory 40 is reduced by an enlargement reduction circuit 46 at a reduction rate of 80% and output to the display memory 42, so that the storage area corresponds to the display area a of the display memory 42. The image is stored at 42a (T4). Therefore, the display control unit 44 displays the stored contents of the storage area 42a of the display memory 42 in the display area a of the CRT display device 24.

In addition, when an image exists in the storage area 42a before the search is performed, the CPU 34 displays a copy instruction of the image before outputting the image from the page memory 40 to the display memory 42. In this case, the display control unit 44 stores the previous search contents stored in the storage area 42b in the storage area 42 corresponding to the display area c by using a copy function. The CPU 34 then reduces the previous search contents stored in the storage area 42a by half in the enlarged reduction circuit 46 and outputs them to the display memory 42. In the storage area 42b corresponding to the display area b, the previously retrieved image is reduced to 1/2 and stored (T5). Next, as the image stored in the page memory 40 is reduced to 80% by the enlargement reduction circuit 46 and output to the display memory 42, it corresponds to the display area a of the display memory 42. The best image (the image currently being processed) is stored in the storage area 42a (T6).

Therefore, the display control unit 44 displays the stored contents of the storage areas 42a, 42b, 42c of the display memory 42 in the display areas a, b, c of the CRT display device 24, respectively (T7). The retrieved image is displayed in the display area a, and the image retrieved the last time and the previous time is reduced to 1/2 in the display areas b and c. As a result, it is possible to grasp what kind of search has been performed and the operability becomes good.

In addition, the recording of the images in the storage areas 42b and 42c of the display memory 42 handles the images in the display memory 42 (the page memory 40 is not used), and the storage area 24a is stored in the storage area 24a. In the case of recording a Korean image, the page memory 40 is handled so that the A3,400 ppi image is always handled as the page memory 40.

In the case of editing an image or the like, an image is searched, an image from which a part of the retrieved image is extracted, and a case in which the image is rotated or enlarged are processed in the same manner as above. Therefore, the image currently being processed is displayed in the display area a, and the previous image and the previous image are displayed in the display areas b and c, respectively. As a result, it is possible to grasp which editing process has been performed and improve operability.

As described above, in the case of the one-screen display, the image processed (manipulated) in the past (previous and previous time) can be displayed on the screen, so that it is possible to grasp how the search or editing process has been performed, so that the front and rear relationship of the screen can be determined. The operability easy to grasp becomes favorable.

In addition, when a CRT display device uses a directional display and displays a vertical image or a horizontal image on the display, the gap can be effectively used.

In the above embodiment, the case where the image displayed in the second display area is a reduction of the image displayed in the first display area has been described. However, the image displayed in the second display area is not limited to the first display area. An enlarged image may be displayed.

In the above embodiment, the case where the entire display area A has three display areas a, b, and c has been described. However, two or more of the total display areas may be used, and the magnification ratio may also be used. It is not limited to 50% and 80% reduction like an Example, You may expand, for example. If one memory area is shifted, the other may be 100% shifted. The shape of the entire display area is not necessarily limited to the forward direction, but may be another shape, for example, a long direction.

[Effects of the Invention]

As described above, according to the present invention, the display means can display a previously processed image in addition to the image currently being processed in the case of single-screen display, and can provide an image processing apparatus having good operability.
