Time display control device, navigation device, method for controlling time displayed, and program
First Claim
1. A time display control device comprising:
- a self-position detecting unit configured to detect a self-position;
a time calculating unit configured to calculate time of a first time zone where the self-position detected using the self-position detection unit exists;
a time display unit configured to display the time calculated using the time calculating unit; and
a display control unit configured to;
i) cause the time display unit to display time of the first time zone continually in an area in an second time zone, which is adjacent to the first time zone, when determining that the self-position moves into the second time zone, the area having a predetermined width from a boundary between the first time zone and the second time zone; and
ii) cause the time display unit to display time of the second time zone when determining that the self-position moves beyond the area.

Abstract
A self-position detecting unit detects a self-position. A time calculating unit calculates a time of a time zone where the self-position detected using the self-position detection unit exists. A time display unit displays the time calculated using the time calculating unit. A display control unit causes the time display unit to display time of the first time zone where the self-position exists continually in an area in a second time zone, which is adjacent to the first time zone, when determining that the self-position moves into the second time zone. The area has a predetermined width from a boundary between the first time zone and the second time zone. The display control unit further causes the time display unit to display time of the second time zone when determining that the self-position moves beyond the area.

1. A time display control device comprising:
-
a self-position detecting unit configured to detect a self-position; a time calculating unit configured to calculate time of a first time zone where the self-position detected using the self-position detection unit exists; a time display unit configured to display the time calculated using the time calculating unit; and a display control unit configured to; i) cause the time display unit to display time of the first time zone continually in an area in an second time zone, which is adjacent to the first time zone, when determining that the self-position moves into the second time zone, the area having a predetermined width from a boundary between the first time zone and the second time zone; and ii) cause the time display unit to display time of the second time zone when determining that the self-position moves beyond the area. - View Dependent Claims (2, 3, 4, 5, 6, 8, 9)

7. A navigation device comprising:
-
a self-position detecting unit configured to detect a self-position; a time calculating unit configured to calculate time of a self-position time zone where the self-position detected using the self-position detection unit exists; a time display unit configured to display the time calculated using the time calculating unit; a destination setting unit configured to set a destination; a route search unit configured to search a route from a start point to the destination set using the destination setting unit; and a display control unit configured to cause the time display unit to display time of a destination time zone where the destination exists continually until arriving at the destination when determining that the self-position moves beyond the boundary and when the route searched using the route search unit intersects a boundary between a start time zone where the start point exists and an adjacent time zone adjacent to the start time zone for a plurality of times.

10. A method for controlling time displayed on a display device, the method comprising:
-
detecting a self-position; calculating time of a first time zone where the self-position exists; calculating time of a second time zone adjacent to the first time zone; determining whether the self-position moves into the second time zone; displaying time of the first time zone continually in an area in the second time zone in response to determination that the self-position moves into the second time zone, the area having a predetermined width from a boundary between the first time zone and the second time zone; and displaying time of the second time zone in response to determination that the self-position moves out of the area into an other area in the second time zone.

11. A method for controlling time displayed on a display device, the method comprising:
-
searching a route from a start point to a destination; determining whether the route intersects a boundary between a start time zone where the start point exists and an adjacent time zone adjacent to the start time zone for a plurality of times; detecting a self-position; determining whether the self-position moves beyond the boundary; calculating time of the start time zone; calculating time of a destination time zone where the destination exists; displaying time of the start time zone before determination that the self-position moves beyond the boundary; and displaying time of the destination time zone continually until arriving at the destination in response to determination that; the self-position moves beyond the boundary; and the route intersects the boundary for a plurality of times.
