Mapping control, boundary condition control when scrolling the screen,
and image editing control.

Next, FIG. 2 is a concrete configuration diagram of the mapping controller shown in FIG. 1. The window controller 101 receives a window operation signal 106 from the control unit 4, outputs the frame memory logical address 107 of the address conversion unit 102 and the window, and exchanges image information 108, 111 with the frame memory 3. The image information and device selection signal 112 are output to the CRT/printer selector 104, and the CRT
Or cause the printer to display or print image information. The address conversion unit 102 converts the frame memory logical address 107 from the optical disk controller 5 or the in-to controller 101 into a frame memory physical address 110 and outputs the frame memory physical address 110 to the frame memory 3. Boundary check and address conversion table control unit 103
checks the window boundary conditions using the window operation signal 106, the frame memory logical address 107 from the optical disk control unit 5 and the window controller 101, and outputs address translation information 109 to the address translation unit 102 based on the result. , to dynamically reconfigure the frame memory physical page address/logical page address conversion table. In addition, the control unit 4
An interrupt/status signal 105 is output.

In addition, in the above configuration, the page link memory 2 is the third
As shown in Figure fa), this is a memory that stores in a matrix the connection relationship between each page of image information that spans multiple pages in terms of a two-dimensional image, and each cell is It corresponds to the page's worth of image information, and holds the physical page address on the optical disk 6 of that page. In addition, the page link memory arranged as shown in ta+ in FIG. 3 is allocated consecutively on the actual memory as shown in FIG. 3 (bl).
is a memory capable of storing four pages of image information, and has a configuration having fixed physical page addresses m1 to m4 as shown in FIG.

The operation of the system having the above configuration will be explained using the operation flowcharts shown in FIGS. 5 and 6 and the operation explanatory diagrams shown in FIGS. 7 to 9. First, the frame memory logical page address and frame memory physical page address will be explained. The frame memory logical page address is
As shown in FIG. 9, it is a page address on a two-dimensional image that is actually displayed and printed on a CRT or printer, and in this embodiment, it has logical page addresses for four pages, and the upper left is the LI The upper right corner is the L2 page, the lower left corner is the L3 page, and the lower right corner is the L4 page.

However, what is output to the CRT or printer is an area for any one page within this. Further, each address of image information in each logical page is called a frame memory logical address. On the other hand, the frame memory physical page address is the actual page address on the frame memory 3 shown in FIG.
There are pages from page to m4 page. Each address of the image information in each physical page at this time is called a frame memory physical address. In the case of this embodiment, it is necessary to allocate frame memory physical page addresses m1 to m4 to frame memory logical page addresses L1 to L4. It is assumed that this is a page address/logical page address conversion table, and is allocated as shown in FIG. 7+a) at the start of operation.

Next, FIG. 5 is an operation flowchart when image information is called. First, when the operator specifies an image identification name from the keyboard 8, the control unit 4 searches the directory information on the magnetic disk 10 (S+), the image attribute information,
Get page link information (physical address) (32, S3
). Next, it is checked from the above attribute information whether the image information consists of a single page or multiple pages (S4), and if it consists of multiple pages, page link information is set in the page link memory 2. (S5). Here, the meaning of consisting of multiple pages means that, for example, when a large map is divided into a matrix, one matrix corresponds to one page, and it means that it is stacked like a book. It's not a thing. Next, information on the first page of the image is read from the optical disk 6 and written into the frame memory 3 as image information 108 from the optical disk control section 5. At this time, the frame memory logical address 107 output at the same time is the logical page address L +
Specify the address within. As a result, in the initial state, each address in the logical page address Lr is converted by the address conversion unit 102 into each address 110 in the physical page address m1 as shown in FIG. Specify the physical address. Further, the image information 108 of the first page at this time is displayed on the CRT via the window controller 101 and the CR'I''/printer selector 104. Note that in the case of multiple pages, the image information 108 is not limited to the first page. , the operator can also specify a specific page.

Next, check if there are multiple pages (S?),
If there are multiple pages, task 8 in FIG.

Task A started by Ss in Figure 5(a)
refers to the page link memory 2 and buffers the image information of the remaining adjacent pages in the frame memory 3 (S9), and task Δ ends. At this time, the frame memory logical address 107 output from the optical disk control unit 5 is of course a logical page address 1.2 to ■-74.
This address is translated into a frame memory physical address 110 by the address translation unit h 102 with the assignment relationship +a+ in FIG.

Now, by the operation described in -, cells 1 to 1 of page link memory 2 are
6, it is assumed that the physical page [phase] to {Oki page link relationship} on the optical disk 6 as shown in FIG. 8 is described. As a result, the control unit 1 performs task 8 in FIG. 5 fb).
The image information of each page on the optical disk 6 written in cells 1.2.3.4 of the page link memory 2 is set to the logical page addresses Ll and L of the frame memory as an initial state.
Buffer to 2, L3, ■, 4. Therefore, the seventh
As shown in FIG. 81, each image information is written to the physical page addresses m1, m?, m3, and m4 on the frame memory 3.

Next, the window control operation will be explained.

By using the mouse 7 (FIG. 1), the operator selects the logical page addresses L1 to L a of the frame memory.
An area for outputting image information to a CRT or printer can be set as a window on the image. That is, the logical image on the frame memory is now as shown in FIG. 9 fa) by the above operation. That is, the logical page address L1 contains the image information of the physical address m1 on the frame memory 3 (where the second +-th column of the optical disc is stored), and the image information of the physical address m1 (where the second +-th column of the optical disk is stored) is stored in the logical page address L1, and m2 (Q),
Image information of m3 <9 is stored in i-3, and image information of m4 (0) is stored in x-t. Now, by moving the mouse 7, the control unit 4 receives the window operation signal 106.
is output to the window controller 101 in the mapping controller 1. As a result, window controller 1-
The frame memory logical address 107 in the range indicated by W (hereinafter referred to as Win 1 to Win 1) of the roller 101 (+8 in FIG. 9) is output to the address conversion unit 102, and the corresponding image information 111 is obtained from the frame memory 3. As a result, the ninth
Image information in the range shown by window W in the figure (al) is
It can be displayed on RT or printed on printer.

By moving the mouse 7 vertically and horizontally, it is possible to freely specify the output range of image information within the images of the logical pages L1 to L4. As described above, image information that spans between pages can also be arbitrarily output. Note that the range of window W is usually one page, but
You can set it arbitrarily below that.

Next, the operation when a boundary condition occurs will be explained. Assume that the window W comes into contact with the lower end of the logical image as shown in FIG. By determining the frame memory logical address 107 from the window controller 101, it is detected that the window W has reached the lower boundary, and the operation flow shown in FIG. 6 f8) is entered. As a result, first, the direction in which the boundary condition occurs is checked (Fig. 6 (al.
s+o). Now, in the case of fb) in FIG. 9, the boundary condition has occurred at the lower end, so the process moves to S+2, and the boundary check and address conversion table control unit 103
Address translation information 109 is sent to the address translation unit 102.
is output, and the physical page address corresponding to the logical page address L l %L2 in the upper half on the image of the frame memory is released.

In the example of FIG. 9(b), the address translation table is shown in FIG. 7(f).
Since the state was a), the physical page addresses m I and m 2 of the frame memory are released. Through this operation, the logical image of the frame memory becomes as shown in FIG. 9 (C1). Next, the address conversion information 109 is output again and the frame memory is reconfigured (S19). FIG.
In bl, since we want to see the image further below, the logical page addresses Ll and L2 in the upper half are reassigned to the physical page addresses m3 and m4 corresponding to the logical page addresses L0 and L a in the lower half, and the lower half The logical page addresses L3, L a of are reassigned to the physical page addresses m + , , m 2 released by the above operation.

As a result, the frame memory physical page address/logical page address conversion table shown in FIG.
). After the above operation, an interrupt/status signal 105 indicating the occurrence of a boundary condition is output to the first control unit 4, and according to the operation flow shown in FIG. A new downward image is manually created at memory physical page addresses m1 and m2.

First, the control unit 4 learns from the interrupt/status signal 105 that the direction of the boundary condition is downward (see FIG.
bls2+). Obtain the information shown in FIG. 8 from the page link memory 2 and obtain the physical page address @0 on the optical disk 6 of the image information corresponding to the cell 5.6 in the lower direction (322).
. Subsequently, the control section 4 instructs the optical disk control section 5 to read the image information at the address. This results in
The optical disk control unit 5 controls the frame memory logical address 1
07, outputs L3 and L4 to the address conversion unit 102, and then outputs the physical page address (
01, C7) Write the image part @108 to the frame memory 3 (S23.524). By the above operation, new downward image information is loaded into the physical page addresses m l and m 2 corresponding to the logical page addresses L3 and L6 in the lower half of the image, and the conceptual configuration of the frame memory is shown in FIG. di. In this state, the new lower half image portion can be freely output using window W.

As described above, when the lower boundary condition occurs, the physical addresses corresponding to the logical addresses L1 and L2 in the upper half of the image are first released, and then the logical addresses L in the lower half are released.
3. Ll and L2 are reassigned to the physical address corresponding to L4. This allows image information in the lower half of the image to be moved to the upper half without data transfer between pages of the frame memory. moreover,
The page link memory 2 automatically transfers downward image information from the optical disk 6 to the logical address L of the frame memory.
3. Can be loaded to L4.

The above operation occurs when the lower edge boundary condition occurs due to the movement of the window W, but the upper edge, left edge, right edge, upper left edge,
Also in the case of the upper right edge, lower left edge, and lower right edge, S of ta+ in Figure 6
11, S13 to S818, the conversion table (FIG. 7) in the address conversion unit 102 is similarly rewritten, and the frame memory is reconfigured.

As described above, according to the present invention, first, by configuring the frame memory into four pages, any area between the pages can be designated by a window and displayed or printed. Furthermore, even if frame memory boundary conditions occur, the image information on the image can be quickly processed by reconfiguring the correspondence between the logical page address of the image and the physical page address on the actual frame memory. It allows for easy movement. In addition, the page link memory allows image information in the direction of the boundary conditions to be automatically loaded from the optical disc into the frame memory.

In the case of the above embodiment, the frame memory has a four-page configuration, and the data transfer unit is also a page unit. However, the frame memory is not limited to this, and the frame memory is set to be slightly larger than one page, and data is transferred in each predetermined data unit. Loading from an optical disc may also be performed.

Furthermore, it goes without saying that the image information storage medium is not limited to an optical disk.

〔Effect of the invention〕

According to the present invention, by providing the page link memory, image information in adjacent directions can be quickly accessed.

Furthermore, since the frame memory is structured into four pages, the display speed does not decrease even if the window moves within that range.

In addition, by adding a frame memory dynamic reconfiguration function, even if frame memory boundary conditions occur, minimal image data transfer is required.

Since it is possible to move windows more quickly than above, and output can be performed across pages, it is possible to dramatically improve the man-machine interface and save resources on hard copies.
