Abstract

An electronic device has a first hand that displays a first time; a second hand that displays a second time; an indicator hand; a detection device that outputs a first time selection signal when it detects a first time selection operation of an input device, and outputs a second time selection signal when it detects a second time selection operation of the input device; a mode setter that sets a first time correction mode to correct the first time when the first time selection signal is received, and sets a second time correction mode to correct the second time when the second time selection signal is received; and a display controller that points the indicator hand to a position other than that of the second hand when the first time correction mode is set, and points the indicator hand to the second hand when the second time correction mode is set.

First claim

What is claimed is:

1. An electronic device comprising:
a first hand that displays a first time;
a second hand that displays a second time and is disposed to a different position than that of the first hand;
an indicator hand disposed to a different position than that of the first hand and second hand;
an interface;
a detector that outputs a first time selection signal when it detects a first time selection operation of the interface, and outputs a second time selection signal when it detects a second time selection operation of the interface;
a mode setter that sets a first time correction mode to correct the first time when the first time selection signal is received, and sets a second time correction mode to correct the second time when the second time selection signal is received; and
a display controller that points the indicator hand to a position other than that of the second hand when the first time correction mode is set, and points the indicator hand to the second hand when the second time correction mode is set.

2. The electronic device described in claim 1 , wherein:
the indicator hand is configured to indicate calendar information corresponding to the first time; and
the display controller sets the indicator hand to indicate the calendar information when the first time correction mode is set.

3. The electronic device described in claim 1 , further comprising:
a dial;
the pivot of the first hand being disposed to the plane center of the dial, and the pivot of the second hand being offset to a position toward the outside circumference from the plane center of the dial.

4. The electronic device described in claim 1 , wherein:
the detector outputs the time zone correction signal when it detects the time zone correction operation of the interface;
the controller further including
a time zone setter that corrects the time zone data of the first time according to the time zone correction signal when the first time correction mode is set the time zone correction signal is received, and corrects the time zone data of the second time according to the time zone correction signal when the second time correction mode is set and the time zone correction signal is received; and
a time corrector that corrects the first time based on the time zone data of the corrected first time, and corrects the second time based on the time zone data of the corrected second time.

5. The electronic device described in claim 4 , further comprising:
a third hand;
the display controller setting the third hand to the time zone data of the first time when the first time correction mode is set, and setting the third hand to the time zone data of the second time when the second time correction mode is set.

6. The electronic device described in claim 1 , wherein:
the first hand includes a first hour hand and a first minute hand;
the second hand includes a second hour hand and a second minute hand; and
when the first time correction mode or the second time correction mode is set, the display controller continues moving the first hour hand, first minute hand, second hour hand, and second minute hand.

7. The electronic device described in claim 1 , wherein:
when a previously set indication time has past after pointing the indicator hand to the second hand, the display controller points the indicator hand to a position other than that of the second hand.

8. The electronic device described in claim 1 , wherein:
the detector outputs a stop indication signal if it detects a stop indication operation of the interface to stop pointing to the second hand with the indicator hand; and
the display controller moves the indicator hand to a position other than that of the second hand if the stop indication signal is received while the indicator hand is pointing to the second hand.

9. The electronic device described in claim 1 , wherein:
to indicate the second hand with the indicator hand, the display controller points the indicator hand to a specific position in a range where a line extending from the pivot of the indicator hand in the indicated direction intersects a circle drawn by the distal end of the second hand.

10. A time correction method of an electronic device, the method comprising:
setting a first time correction mode to correct a first time displayed by a first hand of the electronic device when a first time selection signal is received, the first time selection signal being output from a detector of the electronic device when the detector detects a first time selection operation of an interface of the electronic device;
setting a second time correction mode to correct a second time displayed by a second hand of the electronic device, the second hand being disposed to a different position than that of the first hand and an indicator hand, when a second time selection signal is received, the second time selection signal being output from the detector when the detector detects a second time selection operation of the interface; and
pointing the indicator hand to a position other than that of the second hand when the first time correction mode is set, and pointing the indicator hand to the second hand when the second time correction mode is set.

11. A device-readable medium containing a time correction program comprising instructions to be executed by an electronic device, the instructions to cause the electronic device to perform operations comprising:
setting a first time correction mode to correct a first time displayed by a first hand of the electronic device when a first time selection signal is received, the first time selection signal being output from a detector of the electronic device when the detector detects a first time selection operation of an interface of the electronic device;
setting a second time correction mode to correct a second time displayed by a second hand of the electronic device, the second hand being disposed to a different position than the first hand and an indicator hand, when a second time selection signal is received, the second time selection signal being output from the detector when the detector detects a second time selection operation of the interface; and
pointing the indicator hand to a position other than that of the second hand when the first time correction mode is set, and pointing the indicator hand to the second hand when the second time correction mode is set.
