2. The non-transitory computer readable recording medium according to claim 1, wherein the curbing includes requesting to cancel curbing any one of the frequency of the executing and the accuracy of the acquiring when there is object data registered in a position in the area.

3. The non-transitory computer readable recording medium according to claim 1, wherein the process further comprises:

accepting specifying a distance from the position of the terminal; and

fixing the area on the basis of the specified distance.

4. The non-transitory computer readable recording medium according to claim 1, wherein

the acquiring the position of the terminal includes acquiring the positon of the terminal by performing positioning using signals of a global navigation satellite system, and

the curbing includes curbing frequency of executing computing based on the signals when there is no object data registered in a positon in the area.

5. The non-transitory computer readable recording medium according to claim 1, wherein

the acquiring the position of the terminal includes acquiring the position of the terminal by performing positioning using signals of a global navigation satellite system, and

the curbing includes curbing accuracy of positioning based on the signals when there is no object data registered in a positon in the area.

6. The non-transitory computer readable recording medium according to claim 1, wherein

the acquiring the position of the terminal includes acquiring the position of the terminal by performing positioning using a plurality of positioning units;

and

the curbing includes, when there is no object data registered in a position in the area, curbing any one of frequency of executing the process of acquiring the position of the terminal and accuracy of the acquiring by reducing the number of the positioning units used for the positioning.

7. The non-transitory computer readable recording medium according to claim 6, wherein the positioning units are at least two of a global navigation satellite system, a positioning unit using mobile phone base stations, and a positioning unit using wireless LAN access points.

8. A display control method comprising:

executing a process of acquiring a position of a terminal, using a processor;

fixing an area on the basis of the acquired position of the terminal and determining whether there is object data registered in a position in the fixed area corresponding to the acquired position by referring to a storage that stores positions in which multiple sets of the object data are registered in association with the sets of object data, respectively, using the processor; and

displaying object data on a display when there is the object data registered in a position in the area, and requesting to curb any one of frequency of executing the process of acquiring the position of the terminal and accuracy of the acquiring when there is no object data registered in a position in the area, using the processor.
