After that, the number of stages to be changed is obtained based on the difference DP. For example, when | difference DP | <constant DS1, it is assumed to be one step change (number of steps is 1). When constant DS1 ≦ | difference DP | <constant DS2, change in two steps (the number of steps is 2). Thereafter, the same applies. Finally, when constant DS (n−1) ≦ | difference DP | <constant DSn, N step change (the number of steps N) is set.

  Then, from the current size of the area A displayed on the display 2, the display size is changed by the number of steps obtained based on the | difference DP | to enlarge / reduce the area A.

Whether to enlarge or reduce the area A is determined as follows.
((| DP | == | DX | && DX <= 0) || (| DP | == | DY | && DY <= 0))
When is established, the area A is enlarged,
((| DP | == | DX | &&DX> 0) || (| DP | == | DY | &&DY> 0))
When is established, the area A is reduced.
