Next, FIG. 2 is a concrete configuration diagram of the mapping controller of FIG. The window controller 101 has
The window operation signal 106 is input from the control unit 4, the address conversion unit 102 and the frame memory logical address 107 of the window are output, and the image information 108 and 111 are exchanged with the frame memory 3, and the CR
The image information and the device select signal 112 are output to the T / printer selector 104 to display or print the image information on the CRT or the printer. The address changing unit 102 converts the frame memory logical address 107 from the optical disc controller 5 or the window controller 101 into a frame memory physical address 110 and outputs it to the frame memory 3. The boundary check and address conversion table control unit 103 uses the window operation signal 106,
The boundary condition of the window is checked by the frame memory logical address 107 from the optical disk control unit 5 and the window controller 101, and the address conversion information 109 is output to the address conversion unit 102 based on the result, and the frame memory physical page address / logical The page address translation table is dynamically reconfigured. In addition, the control unit 4
The interrupt / status signal 105 is output to.

In the above configuration, the page link memory 2 has the third
As shown in FIG. (A), it is a memory that stores in a matrix how each page of image information that spans multiple pages has a two-dimensional image-like connection relationship, and each cell is Corresponding to the image information for one page, the physical page address on the optical disk 6 of that page is held. The page link memory having the arrangement shown in FIG. 3 (a) is continuously allocated on the actual memory as shown in FIG. 3 (b). Next, the frame memory 3 is 4
It is a memory capable of storing image information for pages, and has a configuration having fixed physical page addresses m _{1 to} m ₄ as shown in FIG.

The operation of the system having the above configuration will be described with reference to the operation flowcharts of FIGS. 5 and 6 and the operation explanatory diagrams of FIGS. 7 to 9. First, the frame memory logical page address and the frame memory physical page address will be described. The frame memory logical page address is
As shown in Fig. 9, it is actually displayed on the CRT or printer,
This is a page address on a two-dimensional image to be printed, and in the case of the present embodiment, it has a logical page address for four pages, the upper left is L ₁ page, the upper right is L ₂ page, the lower left is L ₃ page, the right below is L ₄ page. However, what is output to the CRT or the printer is an area for one arbitrary page among them. Each address of the image information in each logical page is called a frame memory logical address. On the other hand, the frame memory physical page address is an actual page address on the frame memory 3 shown in FIG. 4, and in the case of the present embodiment, it is from page m _{1 to} page m _{4 as described} above.
Each address of the image information in each physical page at this time is called a frame memory physical address. In the case of the present embodiment, it is necessary to allocate the frame memory physical page addresses m _{1 to} m ₄ to the frame memory logical page addresses L _{1 to} L ₄ .
The allocation is performed by the frame memory physical page address / logical page address conversion table in the address conversion unit 102 (FIG. 2).
It is assumed that they are assigned as shown in Figure (a).

Next, FIG. 5 is an operation flowchart when calling the image information. First, when the operator specifies an image identification name from the keyboard 8, the control unit 4 searches the directory control on the magnetic disk 10 (S ₁ ) and obtains image attribute information and page link information (physical address) (S ₂ , S ₃ ). Then, whether the image information from the attribute information is composed of a single page, examines whether comprise a plurality of pages (S _4), checks whether comprise a plurality of pages (S _4), consist of a plurality of pages to set the page link information to a page link memory 2 when you are (S _5). Here, the meaning of being composed of a plurality of pages means that, for example, when a large map is divided into a matrix, one matrix corresponds to one page, and does not mean a stacked state like a book. Next, the information of the first page of the image is read from the optical disc 6, and is written in the frame memory 3 as the image information 108 from the optical disc control section 5. At this time, the frame memory logical address 10 that is output at the same time
7 specifies an address within the logical page address L ₁ .
As a result, in the initial state, each page in the logical page address L ₁ is processed by the address translation unit 102 in FIG.
Each address 110 in the physical page address m ₁ as shown in
Is converted to a physical address on the frame memory 3. Also, the image information 108 of the first page at this time is
Window controller 101, CRT / printer selector 104
Is displayed on the CRT via. If there are multiple pages,
Not only the first page but also the operator can specify a specific page. Subsequently, checks whether a plurality of pages (S _7), over a period of activation Figure 5 if a plurality of pages task A in (b) as a subtask (S _8), waits for an input. If it is a single page, it will be immediately waiting for input. Fig. 5
Task A exerted activation by S ₈ of (a) refers to the page link memory 2, the image information of the remaining adjacent pages buffered in the frame memory 3 (S _9), the task A is ended To do. At this time, the frame memory logical address 107 output from the optical disc control unit 5 is, of course, an address within the logical page addresses L _{2 to} L ₄ , and the address is converted by the address conversion unit 102 as shown in FIG. It is converted into the frame memory physical address 110 according to the allocation relationship.

Now, with the above operation, the cells 1 to 6 of the page link memory 2 are
A physical page on the optical disk 6 as shown in FIG.
It is assumed that the page link relation of is described. This allows
The controller 1 executes the task A of FIG. 5 (b) to set the image information of each page on the optical disk 6 described in the cells 1, 2, 3, and 4 of the page link memory 2 as the initial state in the frame memory. Buffers to the logical page addresses L ₁ , L ₂ , L ₃ , and L ₄ . Therefore, from FIG. 7 (a), each image information is a physical page address on the frame memory 3.
Written to m ₁ , m ₂ , m ₃ , m ₄ .

Next, the window control operation will be described. Operator by using the mouse 7 (FIG. 1) can be set on the image of the frame logical page address L ₁ ~L memory _4, the output region to the CRT or printer image information as a window. That is, now, the logical image on the frame memory by the above operation is
It looks like Figure (a). That is, the image information of the physical address m ₁ on the frame memory 3 in the logical page address L ₁ (page on the optical disk is stored) is the L ₂ m ₂ (), the L ₃ m ₃ (), M ₄ for L ₄ ()
The image information of is stored. Now, when the mouse 7 is moved, the control unit 4 causes the window operation signal 10
6 is output to the window controller 101 in the mapping controller 1. As a result, the window controller 101 outputs the frame memory logical address 107 in the range indicated by W in FIG. 9A (hereinafter referred to as window) to the address conversion unit 102, and the corresponding image information 111 is sent from the frame memory 3. To get As a result, the image information in the range shown by the window W in FIG. 9A can be displayed on the CRT or printed on the printer via the CRT / printer selector 104. Then, by moving the mouse 7 vertically and horizontally, the output range of the image information can be freely specified within the images of the logical pages L _{1 to} L ₄ . As described above, it is possible to arbitrarily output the image information extending over the pages. The range of the window W is usually one page, but it can be arbitrarily set below it.

Next, the operation when the boundary condition occurs will be described. By the above operation, it is assumed that the window W contacts the lower end of the logical image as shown in FIG. 9 (b), for example. At this time, the boundary check and address conversion table control unit 103 judges that the window W has reached the lower boundary by judging the window operation signal 106 from the control unit 4 and the frame memory logical address 107 from the window controller 101. Is detected, and the operation flow of FIG. 6 (a) is entered. Thus, firstly, the generated direction boundary condition is checked (FIG. 6 (a) S _10). Now, Fig. 9
In the case of (b), the boundary condition occurred at the lower end, so the process is S ₁₂
Then, the boundary check and address conversion table control unit 103 outputs the address conversion information 109 to the address conversion unit 102 and outputs the physical page addresses corresponding to the upper half logical page addresses L ₁ and L ₂ on the image of the frame memory. release. In the example of FIG. 9 (b), the address conversion table is in the state of FIG. 7 (a), so the physical page addresses m ₁ and m _{2 of the} frame memory are released. By this operation, the logical image of the frame memory is shown in FIG.
It becomes like (c). Then, the address conversion information 109 is output again to reconfigure the frame memory (S ₁₉ ). Fig. 9
In (b), since it is desired to see the image further below, the lower half logical page addresses L ₃ and L ₄ correspond to the corresponding physical page addresses m ₃ and m ₄ and the upper half logical page addresses L ₁ and L _{2 respectively.} There are assignment change, physical page address m ₁ released by the action logical page address L _3, L ₄ of the lower half, m ₂
Is reassigned to. As a result, the frame memory physical page address / logical page address conversion table is reconfigured from FIG. 7 (a) to FIG. 7 (b). After the above operation,
A boundary condition generation interrupt / status signal 105 is output to the first control unit 4, and the frame memory physical page address corresponding to the lower half frame memory logical page addresses L ₃ and L _{4 according} to the operation flow of FIG. 6 (b). Input a new downward image to m ₁ and m ₂ .

First, the control unit 4 receives the interrupt / status signal 105,
Know that the direction of the boundary condition is downward (Fig. 6 (b) S
₂₁ ). Obtaining the information of FIG. 8 from the page link memory 2,
Optical disc 6 of image information corresponding to cells 5 and 6 in the downward direction
Get the physical page address, above (S ₂₂ ). Then, the control unit 4 instructs the optical disc control unit 5 to read the image information of the address. As a result, the optical disc control unit 5 outputs L ₃ and L ₄ as the frame memory logical address 107 to the address conversion unit 102, and subsequently the image information of the physical page address on the optical disc 6.
Writing 108 in the frame memory _{3 (S 23, S 24)} . By the above operation, the lower half logical page address on the image
New downward image information is loaded into the physical page addresses m ₁ and m ₂ corresponding to L ₃ and L _4, and the image structure of the frame memory is as shown in FIG. 9 (d). In this state, a new lower half image portion can be freely output using the window W.

As described above, when the lower boundary condition occurs, the physical addresses corresponding to the upper half logical addresses L ₁ and L ₂ are first released on the image, and then the lower half logical addresses L ₃ and L ₄ are released.
L ₁ and L ₂ are reassigned to the physical address corresponding to. As a result, the image information in the lower half of the image can be transferred to the upper half without performing data transfer between pages of the frame memory. Further, the page link memory 2 allows the downward image information to be automatically loaded from the optical disc 6 to the logical addresses L ₃ and L ₄ of the frame memory.

The above operation is performed when the boundary condition of the lower end occurs due to the movement of the window W, but the upper end, the left end, the right end, the upper left end,
Even in the case of the upper right corner, the lower left corner, and the lower right corner, S ₁₁ in FIG.
Similarly, the translation table (FIG. 7) in the address translation unit 102 is rewritten by S _{13 to} S ₁₈ , and the frame memory is reconfigured.

As described above, according to the present invention, first, since the frame memory is made up of four pages, it is possible to specify an arbitrary area between the pages by a window and perform display or printing. Furthermore, even if the boundary condition of the frame memory occurs, the image information on the image can be moved quickly by reconfiguring the correspondence between the logical page address on the image and the physical page address on the actual frame memory. It is possible. In addition, the page link memory allows the image information in the direction of the boundary conditions to be automatically loaded from the optical disc into the frame memory.

In the above embodiment, the frame memory has a 4-page structure and the data transfer unit is a page unit. However, the present invention is not limited to this. You may load from an optical disk.

The image information storage medium is not limited to the optical disc, of course.

〔The invention's effect〕

According to the present invention, by providing the page link memory, it is possible to quickly access the image information in each adjacent direction.

Further, since the frame memory has a 4-page structure, the display speed does not decrease even if the window moves within the range.

In addition, by adding the dynamic reconfiguration function of the frame memory, even if the boundary condition of the frame memory occurs, the minimum image data speed is required.

Since the window can be moved more quickly than the above and the output can be performed over pages, it is possible to dramatically improve the man-machine interface and save resources of hard copy.
