The distance in the X-axis direction from the leftmost side to the point (X ₆ , Y ₆ ) is divided by the width of the enlargement / reduction display target range (step S17).

N = | X ₆ −X ₁ | ÷ (X ₃ −X ₁ ) At this time, since the enlargement / reduction display magnification N is 1 or more, it means that the enlarged display is performed.

As a result of the comparison in step S16, the point (X ₆ ,
If Y ₆ ) falls within the range of the enlargement / reduction display, that is, if X ₃ > X ₆ ≧ X ₁ , the enlargement / reduction display magnification N is calculated as the point (X ₅ , Y ₅ ) to the point (X ₆ , Y ₆ )
This is obtained by dividing the distance in the axial direction by the width of the enlargement / reduction display target range (step S18).

N = | X ₆ −X ₅ | ÷ (X ₃ −X ₁ ) At this time, since the enlargement / reduction display magnification N is 1 or less, it means that the reduced display is performed.

As a result of the comparison in step S16, the point (X ₆ ,
If Y ₆ ) is to the left of the range of the enlargement / reduction display, that is, if X ₁ > X ₆ , the enlargement / reduction display magnification N is calculated as follows: The distance in the X-axis direction from the rightmost side to the point (X ₆ , Y ₆ ) is divided by the width of the enlargement / reduction display target range (step S19).

N = | X ₆ −X ₃ | ÷ (X ₃ −X ₁ ) At this time, the enlargement / reduction display magnification N is 1 or more, which means that the enlarged display is performed.
