, The screen dividing means 1 is obtained. In step A3, the screen dividing means 1 is stored in the screen dividing means / mouse cursor position storage area 32. It is assumed that the screen dividing means 1 divides the image into four, as shown in FIG. When the area where the mouse cursor 41 is located changes to the area 2, the screen division means 1: area 2 is stored in the screen division means / mouse cursor position storage area 32 in steps A4 and A5. In step A6, the address conversion list 2 is obtained from the screen division storage unit 33, and “address A, address B,...” And “address A ″ corresponding to the address conversion list 2 are obtained from the address conversion list group storage unit 35. .. Are obtained and stored in the conversion list address storage area 34. In step 7, the screen image transformation unit 23 transforms the screen image as shown in FIG.

In the address conversion list 2, as for the address A at the pixel position after the transformation, the address A ″ before the transformation is
As the address B of the pixel position after the transformation, the address B ″ before the transformation is designated. Therefore, the pixel information (color) of the address A of the screen image after the transformation is the same as that of the address A ″ of the screen image before the transformation. The same as the pixel information (color), the pixel information (color) at the address B of the transformed screen image
Is the same as the pixel information (color) at the address B ″ of the screen image before deformation.

Referring to FIG. 7A, the screen "GHIJK" of the area 2 where the mouse cursor 41 was located in FIG.
L ”is doubled in the vertical direction. The screen “MNOPQR” in the area 3 in FIG. 6 is hidden. When the mouse cursor 41 is located in the area 1, the result is as shown in FIG.

FIGS. 8 (a) and 8 (b) show an example in which hidden areas are eliminated. Referring to FIG. 8A, the screen “GHIJKL” of the area 2 is displayed in the vertical direction in the same manner as in FIG. 7A.
It has been doubled. The screen “MN” of the area 3 in FIG.
OPQR ”and the screen“ STUVWX ”in the area 4 are shown in FIG.
In (a), both are reduced in half in the vertical direction. Thus, the screen “MNOPQR” in the area 3 is not hidden. When the mouse cursor 41 is located in the area 1, the result is as shown in FIG.

When “vertical double” and “vertical double” are prepared as the deformation mode, and “vertical double” is selected, FIG.
When the image is deformed as shown in FIGS. 8A and 8B and “double height” is selected, it is possible to set such that the image is deformed as shown in FIGS. 8A and 8B.

A process for obtaining a corresponding screen division means by referring to the transformation mode storage unit 31 with respect to the conversion mode given by the input device 1, ie, the heading of the transformation mode storage unit 31, Processing for obtaining the address of the address conversion list using the dividing means and the area of the screen division where the mouse cursor is located (these are stored in the screen dividing means / mouse cursor position storage area 32). Then, a process of transforming the screen image given from the input device 1 based on the address conversion list specified in the conversion list address storage area 34 and outputting it to the output device 4 is performed.

[0052]

As described above, according to the present invention, the area in which the mouse cursor is located changes as the mouse moves, and the address conversion list changes. The effect is that the part can be enlarged.

Also, since the transformation method is given in advance for each pixel by the address conversion list, it is only necessary to change the display address position. hand,
This has the effect of improving the display speed.

Further, since an address conversion list to be given in advance can be prepared according to the difference between the transformation methods, there is an effect that a plurality of transformation methods can be prepared.
