Similarly, a second frame memory 13 is connected to the second cell map 6 and the second video memory 8, and the second frame memory 13
A second display device 14 is connected to 13.

The control unit 2 includes a processor for controlling each unit constituting the display control device 1, a storage device for storing programs, data, and the like that are referred to by the processor. The first and second cell maps 5 and 6 are composed of a RAM for determining cell data on the first and second video memories to be transferred to the first and second frame memories 11 and 13, respectively. The first and second video memories 7 and 8 store RAs for storing cell data of a predetermined number of dots, for example, 16 × 16 dots.
M, etc.

Here, the relationship between the first cell map 5, the first video memory 7, and the first frame memory 11 will be described with reference to FIG.

 FIG. 3 is a memory-related diagram of the cell map system.

As shown in the figure, in the first cell map 5, n addresses from 1 to n are sequentially stored. This address indicates a storage position of each cell data on the first video memory 7. The first video memory 7 is provided with first to n-th areas for storing cell data. Cell data (image data) indicating “○” is stored in the first area, cell data indicating “△” is stored in the second area, and cell data indicating “￥” is stored in the n-th area. . The first frame memory 11 is also provided with first to n-th areas for storing cell data.

Now, the first to fifth items of the first cell map 5 include “2”, “1”, “4”, “n−3”, and “3”, respectively, and
Items include “5”, “n−4”, “n”, “n−2”, “n”
Therefore, the first item of the first cell map 5 is the second item of the first video memory 7, and the second item is the first item of the first video memory 7. , Third
The item indicates the fourth item of the first video memory 7. As a result, the first item in the first frame memory 11 is “△”.
, But the second item has “○” and the third item has “◎”
Will be stored.

The first display device 12 constantly scans the contents of the first frame memory 11 and displays the contents of the first frame memory 11.

The above description also applies to the second cell map 6, the second video memory 8, the second frame memory 13, and the second display device 14.

By the way, when displaying the same contents on both the first display device 12 and the second display device 14, the first and second frame memories 1
Make the contents of 1,13 identical. In other words, the contents of the first cell map 5 and the second cell map 6 are made the same, and the contents of the first video memory 7 and the second video memory 8 are made the same.
As a result, the contents of the first and second frame memories 11 and 13 become the same, and the same display is made on the first and second display devices 12 and 14.

When the contents of the first and second video memories 7 and 8 are different, for example, when the content displayed on the first display device 12 is also displayed on the second display device 14, the first cell map is used. 5 and the contents of the first video memory 7 are copied to the second cell map 6 and the second video memory 8.

(Problems to be Solved by the Invention) When copying contents between the first cell map 5 and the second cell map 6, and between the first video memory 7 and the second video memory 8, the cell map Since the transfer of the address indicating the item of the video memory may be performed, the processing can be completed in a relatively short time. Also in the video memory, when the cell data is a character code or the like, the copying process can be completed in a short time.

However, when the cell data is image data indicating a graph or the like, the time required for copying becomes long, and it is very difficult to quickly switch the display. In the case of color or multi-tone image data, the data amount further increases,
There has been a problem that copying takes much longer.

The present invention has been made in view of the above points, and minimizes the amount of data of copying and transfer performed when the display content of one display device is also displayed on another display device, and promptly displays the content. A display control device capable of performing switching is provided.
