There is a point. In other words, as shown in FIG. 8, there is a problem in that the real image is not displayed in the output area on the screen.

SUMMARY OF THE INVENTION An object of the present invention is to provide an initial display method for binary image information that allows confirmation of a real image at all times.

[Means for Solving the Problem] According to the present invention, it is used when displaying binary image information in an output area set on a screen, and while inputting the binary image information, input means for inputting the number of vertical dots and the number of horizontal dots in the binary image information as output area dot number information, and the number of vertical dots and the number of horizontal dots in the binary image information as binary image dot number information; a center of gravity calculating means for calculating the center of gravity of the binary image information based on the information on the number of binary image dots and outputting it as binary center information; and an output means for outputting the binary image information to the output area so that the center of gravity indicated by the center of gravity information overlaps with the center of gravity indicated by the center of gravity information. The invention will be explained by way of examples.

Referring to FIG. 1, 2. The initial display method of image information according to the present invention is as follows: 1. Manual means 11. Center of gravity calculation means 2. and an output means 3, and the output means 3 outputs and displays binary image information in an output area 4 on the screen as described later.

Referring also to FIG. 2, in step 21, the input means 1 inputs the number of vertical dots and the number of horizontal dots in the output area on the screen.

Next, in step 22, the binary image information and the number of vertical dots and horizontal dots of this binary image information are input manually.

Referring to FIGS. 3 and 4, the single center of gravity calculation means 2 receives the binary image information, and calculates the sum of distances (vertical dot positions) from the top of all black dots on the binary image information (hereinafter referred to as vertical dot positions). At the same time, the number of black dots on the binary image information is determined, and the vertical dot position of the center of gravity of the binary image information is determined from the vertical dot total/number of black dots (step 31). Do the same.

The centroid calculation means 2 calculates the sum of the distances (horizontal dot positions) from the left edge of all black dots on the binary image information (hereinafter referred to as the horizontal dot total), and calculates the binary image information from the horizontal dot total/number of black dots. Find the horizontal dot position of the center of gravity (step 32)
). In this way.

The center of gravity calculation means 2 calculates the center of gravity of the binary image information.

Next, referring to FIGS. 5 and 6, the output means 3 receives binary image information from the input means 1 and also receives the center of gravity of the binary image information from the center of gravity calculation means 2.

Binary image information is output to the output area so that the upper right coordinates (upper right corner, indicated by a cross in FIG. 6) of the output area on the screen and the center of gravity of the binary image information overlap.

That is, as shown in FIG. 5, the output means 3.

First, in step 501, the value "1" is set to Pl.

The "vertical dot position of the center of gravity of binary image information" is set in P2. Next, in step 502, it is checked whether (the number of horizontal dots in the output area on the screen)<(the horizontal dot position of the center of gravity of the binary image information). (Number of horizontal dots in the output area on the screen)
If <(horizontal dot position of the center of gravity of the binary image information), the process proceeds to step 503, where the value "Y°" is set in P3 and the value of (horizontal dot position of the center of gravity of the binary image information) - (horizontal dot position of the center of gravity of the binary image information) on the screen is set in P4. (number of horizontal dots in the output area) -1.

On the other hand, (number of horizontal dots in the output area on the screen)≧(horizontal dot position of the center of gravity of the binary image information).

In step 504, P3 is set to (number of horizontal dots in the output area on the screen)-(horizontal dot position of the center of gravity of the binary image information)+1.

In this way, in steps 501 to 504, the display start vertical dot position and display start horizontal dot position in the output area on the screen and the display start vertical dot position and display start horizontal dot position on the binary image information are determined.

Then, when step 503 or 504 is completed, in step 505 Wl (the number of vertical dots in the output area on the screen) is
, set W2 as (the number of vertical dots in the binary image information) - P2+1, and set W3 as (the number of horizontal dots in the output area on the screen) - P3+1.
and set W4 to (number of horizontal dots in binary image information) - P4+1.

When step 505 is completed, in step 507 Wl<
Check whether it is W2. As a result.

If Wl<W2, in step 508 Wl is set to Sl and Sl, respectively. On the other hand, if Wl≧W2,
In step 509, W2 is set to S] and S2, respectively. Then, when step 508 or 509 is completed,
Proceed to step 510.

In step 510, it is checked whether W3<W4, and W
If 3<W4, step 511 sets W3 to each of S3 and S4. On the other hand, if W3≧W4, W4 is set in each of S3 and S4 in step 512.

When step 511 or 512 is completed, the output means 3 executes step 513. In step 513, the display on the binary image information is started for the display start vertical dot position PI, the display start horizontal dot position WP3, the display vertical dot number Sl, and the display horizontal dot number 83 on the output area on one screen. A portion from the vertical dot position P2 and the display start horizontal dot position P4 to the display vertical dot number S21 and the display horizontal dot number 84 is displayed.

That is, in steps 505 to 512, the number of displayed vertical dots and the number of displayed horizontal dots in the output area on the screen and the number of displayed vertical dots and the number of displayed horizontal dots on the binary image information are determined. Then, in step 513, binary image information is displayed on the screen from the display start vertical dot position 1 display start horizontal dot position obtained in steps 501 to 504 to the display vertical dot number 1 display horizontal dot number obtained in steps 507 to 512. will be displayed in the output area.
