10A, when the mobile terminal travels at a higher speed, the distance between the icon i indicating the mobile terminal and the center point CP of the map screen is smaller than the distance Is longer than the distance between the icon (i) indicating the mobile terminal and the center point (CP) of the map screen when traveling at a lower speed.

This reflects the fact that the faster the speed of the mobile terminal (especially when mounted on the vehicle), the greater the interest in the front area of the wider mobile terminal D in the running direction.

10A, the scale of the second map BR displayed when the mobile terminal travels at a higher speed is a map in which the mobile terminal travels at a lower speed as shown in FIG. 10B Is smaller than the scale of the second map BR displayed in the case of the second map BR.

This is because the faster the speed of the mobile terminal (particularly, when mounted on the vehicle) is, the more attention is paid to the area ahead of the driving direction D of the wider mobile terminal, Even if the display area of the second map BM expressing the rear area of the second map BM is different, the second map BM always displays the area of the similar real area.

11A and 11B are display screens of a mobile terminal performing a navigation function according to another embodiment of the present invention.

11A shows a deformation map displayed when the mobile terminal is traveling at a speed of 100 km / h, FIG. 11B shows a deformation map displayed when the mobile terminal is traveling at a speed of 40 km / h, It is.

The deformation map of the present embodiment displays the area FR ahead of the traveling direction D of the mobile terminal in a wider range than the rear area BR of the traveling direction D when the mobile terminal is traveling. This is almost the same as the case of the embodiment of Figs. 6A and 6B.

11A, when the mobile terminal travels at a higher speed, the distance between the icon i indicating the mobile terminal and the center point CP of the map screen is shifted as shown in FIG. 10B It can be seen that the distance between the icon i indicating the mobile terminal and the center point CP of the map screen is longer when the terminal travels at a lower speed.

This reflects the fact that the faster the speed of the mobile terminal (especially when mounted on the vehicle), the greater the interest in the front area of the wider mobile terminal D in the running direction.
