Abstract

According to one embodiment, an electronic device includes: a display; a touch panel provided on the display; a lock controller configured to shift the electronic device to a locked state and configured to cancel the locked state when a touch input in a predetermined position of the touch panel is detected; and an unlock screen display controller configured to generate an image as a reference of the position of the touch input for cancellation of the locked state, display the image on the display, and control a display form of the image so that the display form corresponding to a first timing is different from the display form corresponding to a second timing.

Claims

1. An electronic device comprising:

a display;

a touch panel provided on the display;

a lock controller configured to shift the electronic device to a locked state and configured to cancel the locked state when a touch input in a predetermined position of the touch panel is detected; and

an unlock screen display controller configured to generate an image as a reference of the position of the touch input for cancellation of the locked state, display the image on the display, and control a display form of the image so that the display form corresponding to a first timing is different from the display form corresponding to a second timing.

2. The electronic device according to claim 1, wherein

the unlock screen display controller controls a position of the image as the display form.

3. The electronic device according to claim 1, wherein

the unlock screen display controller controls positions of the image and other objects displayed on the display as the display form.

4. The electronic device according to claim 1, wherein

the unlock screen display controller controls a size of the image as the display form.

5. The electronic device according to claim 1, wherein

the unlock screen display controller controls an angle of the image as the display form.

6. The electronic device according to claim 1, wherein

the unlock screen display controller controls a shape of the image as the display form.

7. The electronic device according to claim 1, wherein

the unlock screen display controller controls at least two of a position, a size, an angle and a shape of the image as the display form.

8. The electronic device according to claim 1, further comprising:

a detection unit configured to detect an attitude of the electronic device;

wherein

the unlock screen display controller controls the display form of the image according to a result detected by the detection unit.

9. A recording medium configured to store a program executed in an electronic device equipped with a display and a touch panel provided on the display, comprising:

shifting the electronic device to a locked state;

cancelling the locked state when a touch input in a predetermined position of the touch panel is detected;

generating an image as a reference of the position of the touch input for cancellation of the locked state and displaying the image on the display portion; and

controlling a display form of the image so that the display form corresponding to a first timing is different from the display form corresponding to a second timing.

10. A lock control method comprising:

shifting the electronic device to a locked state;

generating an image as a reference of a position of a touch input on a touch panel for cancellation of the locked state and displaying the image on the display;

controlling a display form of the image so that the display form corresponding to a first timing is different from the display form corresponding to a second timing; and

canceling the locked state when a touch input in a predetermined position of the touch panel is detected.
