Abstract

An electronic device has a reception device; a display device; an input device; a display controller that controls the display device to display the set time zone data when a first operation of the input device instructing displaying time zone data is detected; a positioning driver that operates the reception device to run a reception process and acquire positioning information when a second operation of the input device instructing starting reception in the navigation mode is detected while time zone data is displayed on the display device; and a time zone setter that sets time zone data based on the acquired positioning information.

First claim

What is claimed is:

1 . An electronic device comprising:
a receiver that receives satellite signals; a display; an interface; a display controller that controls the display to display the set time zone data when a first operation of the interface instructing displaying time zone data is detected; a positioning driver that drives the receiver to run a reception process of the satellite signal in a navigation mode and acquire positioning information when a second operation of the interface instructs starting reception of the satellite signal in the navigation mode while the display is displaying time zone data; and a time zone setter that sets time zone data based on acquired positioning information.

2 . The electronic device described in claim 1 , wherein:
the positioning driver executes the reception process if the second operation is detected when time zone data is not displayed by the display.

3 . The electronic device described in claim 1 , further comprising:
a timekeeper that operates the receiver to run the reception process in the timekeeping mode to acquire time information when a third operation of the interface instructing starting reception in the timekeeping mode is detected when time zone data is not displayed by the display.

4 . The electronic device described in claim 3 , wherein:
the timekeeper executes the reception process if the third operation is detected when time zone data is not displayed by the display.

5 . The electronic device described in claim 3 , wherein:
the display has a hand; and the display controller sets the hand to indicate the set time zone data when the first operation is detected, and while the hand indicates the time zone data,
sets the hand to indicate the navigation mode if the second operation is detected, and
sets the hand to indicate the timekeeping mode if the second operation is detected.

6 . The electronic device described in claim 1 , wherein:
the display controller displays the reception result on the display if a fourth operation of the interface instructing displaying the reception result is detected while time zone data is displayed on the display.

7 . The electronic device described in claim 1 , further comprising:
a mode setter that selects and sets either a time zone confirmation mode or time zone setting mode based on operation of the interface; the display controller displaying the set time zone data on the display if a confirm time zone operation, which is the first operation of the interface, is performed and the time zone confirmation mode is set by the mode setter; the display controller displaying the set time zone data on the display, and the time zone setter sets the time zone data according to the change time zone operation of the interface, if a set time zone operation of the interface is performed and the time zone setting mode is set by the mode setter; and the positioning driver executing the reception process if the second operation is detected when the time zone confirmation mode is set, and not executing the reception process if the second operation is detected when time zone setting mode is set.

8 . The electronic device described in claim 1 , further comprising:
a mode setter that selects and sets either a time zone confirmation mode or time zone setting mode based on operation of the interface; the display controller displaying the set time zone data on the display if a confirm time zone operation, which is the first operation of the interface, is performed and the time zone confirmation mode is set by the mode setter; the display controller displaying the set time zone data on the display, and the time zone setter setting the time zone data according to the change time zone operation of the interface, if a set time zone operation of the interface is performed and the time zone setting mode is set by the mode setter; and the positioning driver executing the reception process if the second operation is detected when the time zone confirmation mode is set, and executing the reception process if the second operation is detected when time zone setting mode is set.

9 . The electronic device described in claim 7 , wherein:
the interface includes a crown and a button; and the mode setter detects the confirm time zone operation when the button is pushed while the crown is at the 0 stop.

10 . The electronic device described in claim 7 , wherein:
the mode setter ends the time zone confirmation mode if a stop time zone confirmation operation of the interface instructing ending the time zone confirmation mode is detected.

11 . The electronic device described in claim 7 , wherein:
the mode setter ends the time zone confirmation mode if a previously set hold-mode time passes without the interface being operated after the time zone confirmation mode is set.

12 . A control method of an electronic device, the control method comprising:
displaying time zone data on a display of the electronic device when a first operation of an interface of the electronic device instructing displaying time zone data is detected; driving a receiver of the electronic device to run a reception process to receive satellite signals in a navigation mode and acquire positioning information when a second operation of the interface instructing starting reception in the navigation mode is detected while the display is displaying time zone data; and setting time zone data based on acquired positioning information.
