In the embodiment described above, when the acquired position information satisfies a predetermined position condition, that is, when the fixed display is sufficient, the map data is displayed in a fixed manner without impairing the user's convenience. Electricity can be achieved.
Further, when the acquired position information does not satisfy the predetermined position condition, that is, when the fixed display is not suitable, the convenience of the user can be ensured by updating and displaying the map data.
In addition, when the fixed display is sufficient, the map data is fixedly displayed, and further, the power consumption to hold the display contents can be suppressed by suppressing the power supply to the display unit.
In addition, when the fixed display is sufficient, the map data is displayed in a fixed manner, and further, the acquisition of the position information is suppressed, thereby reducing the power consumption for acquiring the position information.

In addition, by setting the position condition as “whether the acquired position information is included in a predetermined range” or “whether the acquired position information is included in predetermined map data”, For example, in the case of map data that is sufficiently displayed by a fixed display because the user knows it well, such as the area around the user's home or the area where the user frequently visits, the display is updated without impairing the user's convenience. Power consumption can be suppressed.
Further, by setting the position condition as “whether or not the map data including the acquired position information and the target position information can be displayed at a predetermined scale”, the user position and the target position are included. Therefore, in the case of sufficient map data with fixed display, it is possible to suppress power consumption for updating the display without impairing user convenience.

Also, if the battery level is low or the operation mode is set to reduce power consumption, that is, if it is necessary to reduce power consumption more than usual, the map data is fixed if the fixed display is sufficient. By displaying, the power consumption for updating the display can be suppressed without impairing the convenience of the user.
In addition, by notifying that the map data has been fixedly displayed, the user can recognize that the map has been fixedly displayed, so that the user can be prevented from mistaking the fixed display and the update display.
Also, in the case of fixed display, map data is displayed on a display means suitable for fixed display, and in the case of update display, map data is displayed on a display means suitable for update display. Further, it is possible to display the map data on the display means, and to prevent the user from mistaking the fixed display and the update display.

In the above-described embodiment, the fixed display is black and white display and the update display is color display so that the user can distinguish between them. However, the present invention is not limited to these display methods. For example, any display method may be used as long as the display method allows the user to distinguish between the fixed display and the update display, such as displaying a fixed display mark or an update display mark or changing the display color.
