Abstract

According to an aspect, a mobile electronic device includes a display unit, an operating unit, and a control unit. The display unit displays a lock screen in a first locked state. The operating unit receives an input of an operation. The control unit cancels the first locked state when an input of a first operation is detected through the operating unit while the lock screen is displayed on the display unit, and enters a second locked state when an input of a second operation is detected through the operating unit while the lock screen is displayed on the display unit.

Claims

1. A mobile electronic device comprising:

a display unit for displaying a lock screen;

an operating unit for receiving an input of an operation; and

a control unit for cancelling a first locked state when an input of a first operation is detected through the operating unit while the lock screen is displayed on the display unit, and entering a second locked state when an input of a second operation is detected through the operating unit while the lock screen is displayed on the display unit,

wherein the first operation and the second operation are contact operations that start from a contact to a same location, respectively, and

wherein the lock screen includes an object, and the first operation and the second operation start from the contact to the display area of the object, respectively.

2. The mobile electronic device according to claim 1, wherein

the first locked state is a locked state for reducing false operation, and

the second locked state is a locked state for reducing unauthorized use.

3. The mobile electronic device according to claim 1, wherein

a control unit is configured to cancel the second locked state when an input of a different operation from the first operation is detected through the operating unit.

4. The mobile electronic device according to claim 1, wherein

a control unit is configured to display a first lock screen on the display unit in the first locked state, and to display a second lock screen on the display unit in the second locked state.

5. The mobile electronic device according to claim 1, wherein

the second locked state requires more complex operation to be canceled than the first locked state.

6. The mobile electronic device according to claim 1, wherein

the first operation is an operation to sweep on a trace after the contact to the display area, and

the second operation is an operation to sweep on a trace different from that of the first operation after the contact to the display area.

7. The mobile electronic device according to claim 1, wherein

the first operation is an operation to sweep to a set goal point after the contact to the display area, and

the second operation is an operation to sweep to a different point from the goal point.

8. The mobile electronic device according to claim 7, wherein

the second operation is an operation to move the object toward outside the lock screen.

9. The mobile electronic device according to claim 1, wherein

the second operation is an operation to rotate the object after the contact to the display area.

10. The mobile electronic device according to claim 1, wherein

the lock screen displays a locked state display object indicating the locked state, and

the second operation is an operation to imply to change a state of the locked state display object.

11. The mobile electronic device according to claim 1, wherein,

the control unit is configured to display the lock screen on the display unit when an operation is detected through the operating unit in a power saving state where no image is displayed on the display unit.

12. A control method of a mobile electronic device including a display unit and an operating unit, the control method comprising:

displaying a lock screen on the display unit in a first locked state;

detecting an operation through the operating unit while displaying the lock screen on the display unit;

cancelling the first locked state when an input of a first operation is detected at the detecting; and

entering a second locked state when an input of a second operation is detected at the detecting,

wherein the first operation and the second operation are contact operations that start from a contact to a same location, respectively, and

wherein the lock screen includes an object, and the first operation and the second operation start from the contact to the display area of the object, respectively.

13. The control method according to claim 12, wherein

the first locked state is a locked state for reducing false operation, and

the second locked state is a locked state for reducing unauthorized use.

14. The control method according to claim 12, further comprising

canceling the second locked state when an input of a different operation from the first operation is detected through the operating unit.

15. A non-transitory storage medium that stores a control program for causing, when executed by a mobile electronic device including a display unit and an operating unit, the mobile electronic device to execute:

displaying a lock screen on the display unit in a first locked state;

detecting an operation through the operating unit while displaying the lock screen on the display unit;

cancelling the first locked state when an input of a first operation is detected at the detecting; and

entering a second locked state when an input of a second operation is detected at the detecting,

wherein the first operation and the second operation are contact operations that start from a contact to a same location, respectively, and

wherein the lock screen includes an object, and the first operation and the second operation start from the contact to the display area of the object, respectively.
