Abstract

A mobile terminal device includes a display control module 100 performing display control on display modules 11 and 21 and a setting module 100 setting an icon to be kept secret according to a setting operation. In this arrangement, the display control module 100 performs control such that the secret icon set by the setting module 100 is not included in an icon display screen.

Claims

1. A mobile terminal device comprising:

a display operable to display an icon;

an operation accepting module operable to accept an operation input;

a setting module operable to set an icon to be kept secret according to a setting operation;

a display control module operable to control the display such that, in a first mode, the secret icon set by the setting module is not included in an icon display screen, and, in a second mode, the secret icon set by the setting module is included in the icon display screen;

a memory module operable to register an operation input as a permission operation which permits the second mode; and

a detection module operable to detect the permission operation based on a comparison of the registered operation input with an operation input accepted by the operation accepting module;

wherein, when the display is in the first mode and the permission operation is detected by the detection module, the display control module switches the display to the second mode such that the secret icon is included in the icon display screen, and

wherein, when the icon display screen is closed, the display control module cancels the second mode and switches to the first mode such that, when the icon display screen is subsequently redisplayed without detection of the permission operation, the secret icon is not included in the icon display screen.

2. The mobile terminal device according to claim 1, further comprising a touch panel, wherein the permission operation comprises a figure drawn on the touch panel.

3. The mobile terminal device according to claim 2,

wherein the display comprises a first display and a second display,

wherein the first and second displays are configured to switch between a closed state in which only the first display is exposed and an open state in which both the first display and the second display are exposed, and

wherein, when the permission operation is detected while the first and second displays are in the closed state and then the first and second display are switched to the open state, the display control module switches the display to the second mode such that the secret icon is included on the icon display screen displayed on one or both of the first display and the second display.

4. The mobile terminal device according to claim 3, wherein, when the first and second displays are in the open state, a secret application corresponding to the secret icon is under execution, an operation screen for the secret application is displayed, and then the first and second displays are switched to the closed state, the secret application continues to be executed but the display control module stops displaying the operation screen for the executing secret application.

5. The mobile terminal device according to claim 4, wherein, when the permission operation is detected while the first and second displays are in the closed state after stoppage of display of the operation screen and then the first and second displays are switched to the open state, the display control module displays again the operation screen for the secret application.

6. The mobile terminal device according to claim 4, wherein, when the permission operation is not detected while the first and second displays are in the closed state after stoppage of display of the operation screen and then the first and second displays are switched to the open state, the display control module does not display the operation screen for the secret application.

7. The mobile terminal device according to claim 3, wherein, after the permission operation is detected by the detection module while the first and second displays are in the closed state, when the first and second displays are not switched to the open state within a predetermined time limit, the display control module invalidates the permission operation.

8. The mobile terminal device according to claim 3, wherein the permission operation is accepted when the operation input is performed to the first display while the first and second displays are in the closed state.

9. The mobile terminal device according to claim 8, wherein the operation accepting module comprises a touch sensor arranged on the first display.
