DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. An image storage area 14 in the memory 13 stores an image to be drawn.

FIG. 2 shows an operation when an image is displayed on the graphic display 12 in the same size as in the prior art. In the figure, 21 is a circle before the image storage areas 14 and 22 are drawn. The later image storage areas 14 and 23 are graphic displays 12 and 24 in which the image stored in the image storage area 14 is displayed in its original size. The graphic displays 12 and 24 are in the middle of drawing a circle on the displayed image. , 25
The graphic displays 12 and 26 that have finished drawing a circle on the displayed image represent the image storage area drawing device 18.

FIG. 3 shows an example of an operation for displaying a reduced image on the graphic display 12, in which 31 is an image storage area before drawing a circle and 32 is an image storage area after drawing a circle. Reference numerals 14 and 33 represent reduced images of the image stored in the image storage area 14. Graphic displays 12 and 34 represent a circle on the displayed image. Graphic displays 12 and 35 are in the middle of drawing. The graphic displays 12 and 36 that have drawn the circle on the image represent the image storage area drawing devices 18 and 37, which represent the coordinate information conversion device.

FIG. 4 shows an example of an operation for enlarging and displaying an image on the graphic display 12, where 41 is an image storage area 14 before drawing a circle and 42 is an image storage area after drawing a circle. Reference numerals 14 and 43 indicate that the image stored in the image storage area 14 is enlarged and displayed. Graphic displays 12 and 44 indicate that the graphic displays 12 and 45 are displaying a circle on the displayed image. The graphic displays 12 and 46 that have drawn the circle on the image represent the image storage area drawing devices 15 and 47, which represent the coordinate information conversion device.

First, the case where an image is displayed on the graphic display 12 as it is will be described with reference to FIG. The image stored in the image storage area 14 is displayed at the same size on the graphic display 12. The mouse device 11 is used to specify the center portion of the position on the displayed image where the circle is to be drawn. When the mouse device 11 is moved, a circle passing through the moved point centered on the previously designated point is drawn by the graphic display drawing device 17 on the graphic display. Therefore, the mouse device 11 is moved until the circle becomes the circle to be drawn. Once the circle you want to draw becomes mouse device 1 again
The part that becomes the decision point is designated by 1. When the decision point is designated, the image storage area drawing device 18 draws a circle on the image stored in the image storage area 14 by using the coordinate information of the center point and the decision point read by the mouse device 11. Image storage area 14 in which a circle is drawn
The image inside is displayed again on the graphic display 12, and the drawing process of the circle ends.

Next, the image is reduced by using FIG.
A case where the entire image is displayed on the graphic display 12 will be described. The image stored in the image storage area 14 is reduced and converted by the image magnification conversion device 15, and the result is converted into the graphic display 1.
Display on 2. The mouse device 11 is used to specify the center portion of the position on the displayed image where the circle is to be drawn. When the mouse device 11 is moved, a circle passing through the moved point centered on the previously specified point is drawn by the graphic display drawing device 17 on the graphic display. Therefore, the mouse device 11 is drawn until the circle becomes the desired circle.
To move. When the circle to be drawn is reached, the mouse device 11 is used again to specify the portion to be the decision point. When the decision point is designated, the coordinate information of the center point and the decision point read by the mouse device 11 is converted by the coordinate information conversion device 16,
The image storage area drawing device 18 is added to the image stored in the image storage area 14 using the converted coordinate information.
Draws a circle. The image in the image storage area 14 in which the circle has been drawn is converted into an image magnification conversion device 15 again.
