Abstract

An electronic apparatus includes a processor and a memory. The processor executes a program stored in the memory to perform operations including: acquiring a series of position information of a user; detecting whether or not a loss part, in which position information corresponding to a predetermined time or a predetermined number of times of measurement is lost, is present in the series of position information acquired; and specifying the detected loss part in a case where the loss part is detected.

Claims

1. An electronic apparatus comprising:

a processor; and

a memory,

wherein the processor executes a program stored in the memory to perform operations comprising;

acquiring a series of position information of a user;

judging whether or not a loss part is present in the series of position information acquired; and

in a case where it is judged that the loss part is present, specifying a predetermined part including the loss part and an adjacent part which is adjacent to the loss part,

wherein the adjacent part is arranged after the loss part and has a predetermined time length which is determined based on a predetermined ratio to the loss part, and

wherein the predetermined part is a part that is not appropriate for display in the series of position information.

2. The electronic apparatus according to claim 1, wherein the processor is further configured to output the series of position information in which the predetermined part is specified.

3. The electronic apparatus according to claim 2, wherein outputting the series of position information further comprises outputting data acquired by excluding the predetermined part from the series of position information.

4. The electronic apparatus according to claim 3, wherein specifying the predetermined part further comprises variably setting a length of a period in which position information subsequent to the loss part is not output.

5. The electronic apparatus according to claim 3, wherein, as a length of the loss part increases, specifying the predetermined part further comprises setting a length of a period in which position information subsequent to the loss part is not output.

6. The electronic apparatus according to claim 3, wherein in a case where a length of the loss part is equal to or longer than a threshold, specifying the predetermined part further comprises setting a period in which position information subsequent to the loss part is not output.

7. The electronic apparatus according to claim 3, wherein specifying the predetermined part further comprises:

discarding or invalidating the position information acquired in a period in which the position information subsequent to the loss part is not output, and

maintaining the position information acquired after elapse of the period in which the position information subsequent to the loss part is not output.

8. The electronic apparatus according to claim 2, wherein specifying the predetermined part further comprises variably setting a length of a period in which position information subsequent to the loss part is not output.

9. The electronic apparatus according to claim 8, wherein, as a length of the loss part increases, specifying the predetermined part further comprises setting a length of a period in which position information subsequent to the loss part is not output.

10. The electronic apparatus according to claim 8, wherein in a case where a length of the loss part is equal to or longer than a threshold, specifying the predetermined part further comprises setting a period in which position information subsequent to the loss part is not output.

11. The electronic apparatus according to claim 8, wherein specifying the predetermined part further comprises:

discarding or invalidating the position information acquired in the period in which the position information subsequent to the loss part is not output, and

maintaining the position information acquired after elapse of the period in which the position information subsequent to the loss part is not output.

12. The electronic apparatus according to claim 2, wherein, as a length of the loss part increases, specifying the predetermined part further comprises setting a length of a period in which position information subsequent to the loss part is not output.

13. The electronic apparatus according to claim 12, wherein in a case where the length of the loss part is equal to or longer than a threshold, specifying the predetermined part further comprises setting the length of the period in which the position information subsequent to the loss part is not output.

14. The electronic apparatus according to claim 12, wherein specifying the predetermined part further comprises:

discarding or invalidating the position information acquired in the period in which the position information subsequent to the loss part is not output, and

maintaining the position information acquired after elapse of the period in which the position information subsequent to the loss part is not output.

15. The electronic apparatus according to claim 2, wherein in a case where a length of the loss part is equal to or longer than a threshold, specifying the predetermined part further comprises setting a period in which position information subsequent to the loss part is not output.

16. The electronic apparatus according to claim 15, wherein specifying the predetermined part further comprises:

discarding or invalidating the position information acquired in the period in which the position information subsequent to the loss part is not output, and

maintaining the position information acquired after elapse of the period in which the position information subsequent to the loss part is not output.

17. The electronic apparatus according to claim 2, wherein specifying the predetermined part further comprises:

discarding or invalidating the position information acquired in a period in which the position information subsequent to the loss part is not output, and

maintaining the position information acquired after elapse of the period in which the position information subsequent to the loss part is not output.

18. A position specifying system comprising:

a first electronic apparatus that includes a processor and a memory; and

a second electronic apparatus that includes a processor and a memory,

wherein in at least one of the first electronic apparatus and the second electronic apparatus, the processor executes a program stored in the memory to perform operations including;

acquiring a series of position information of a user;

judging whether or not a loss part is present in the series of position information acquired; and

in a case where it is judged that the loss part is present, specifying a predetermined part including the loss part and an adjacent part which is adjacent to the loss part,

wherein the adjacent part is arranged after the loss part and has a predetermined time length which is determined based on a predetermined ratio to the loss part, and

wherein the predetermined part is a part that is not appropriate for display in the series of position information.

19. A position specifying method executed by a processor of an electronic apparatus under control of a program stored in a memory, the position specifying method comprising:

acquiring a series of position information of a user;

judging whether or not a loss part is present in the series of position information acquired; and

in a case where it is judged that the loss part is present, specifying a predetermined part including the loss part and an adjacent part which is adjacent to the loss part,

wherein the adjacent part is arranged after the loss part and has a predetermined time length which is determined based on a predetermined ratio to the loss part, and

wherein the predetermined part is a part that is not appropriate for display in the series of position information.

20. A non-transitory computer-readable storage medium storing a program that is executable by a computer that comprises a processor, the program being executable to cause the computer to perform operations comprising:

acquiring a series of position information of a user;

judging whether or not a loss part is present in the series of position information acquired; and

in a case where it is judged that the loss part is present, specifying a predetermined part including the loss part and an adjacent part which is adjacent to the loss part,

wherein the adjacent part is arranged after the loss part and has a predetermined time length which is determined based on a predetermined ratio to the loss part, and

wherein the predetermined part is a part that is not appropriate for display in the series of position information.
