The user may display a spotlight mode menu as shown in FIG. 3 by selecting a mobile phone setting menu or by long touching a specific position on a screen on which a plurality of menus are displayed. In the spotlight mode menu, a user selects a spotlight menu, sets a shape (eg, a square), a size, and a position (eg, a dial icon) of the spotlight area to be displayed on the menu screen, and then uses the adjustment bar to adjust the brightness of the spotlight area. And transparency (or brightness) of the area (the part which looks dark) except for the spotlight area. In this case, the controller 180 allows the user to directly check the brightness and the transparency that change according to the movement of the adjustment bar.

Areas other than the spotlight area (the part that looks dark) include a method of preventing power from being applied and a darker than an initial menu screen in order to reduce power consumption.

When the user selects the OK button after the detailed information on the spotlight area is set, the controller 180 generates a spotlight area 50 that accepts a "call" icon, as shown in FIG. 4, and the spotlight area. (50) is displayed at the brightness set by the user. In addition, the remaining area is darkened with the set transparency. Accordingly, the user selects a dial icon in the spotlight area 50 to perform a dial.

In the present invention, the spotlight region 50 may be variously applied. The spotlight area 50 can be moved, copied and deleted, and can be combined if necessary. The controller 180 detects the movement, copying, and deletion of the spotlight area 50 through a sensor and performs a control operation corresponding thereto.

5A to 5D show various application examples of the spotlight area 50 possible on the menu screen.

As shown in FIG. 5A, the movement of the spotlight area 50 is made by touching the edge (edge) and dragging it to a desired point. If the spotlight area 50 is set to the maximum size in the horizontal direction, only the moving distance is possible, and if the spotlight area 50 is set to the maximum size in the vertical direction, only the left and right movements are possible. In other cases, it is possible to move in a diagonal direction as well as up, down, left, and right.

As illustrated in FIG. 5B, the user may touch (eg, multi-touch) the spotlight area 50 to generate a spotlight area having the same size, and the generated spotlight area may be moved to a desired position by a user's touch & drag operation. Is moved to.

As illustrated in FIG. 5C, the spotlight area 50 may be enlarged or reduced by a touch operation of the user, that is, an operation of spreading or pinching two fingers out.

The spotlight area 50 is fixed unless the user moves it. Therefore, as shown in FIG. 5D, when the user slides the menu screen in the spotlight area 50 to the left, the left and right screens are moved, and the menu of the right screen is displayed in the spotlight area 50.

6 shows an example of deleting the spotlight area 50 from the menu screen.

The spotlight area 50 may be arbitrarily deleted by the user. As shown in FIG. 6, since the delete button is displayed when the user long touches a specific border (upper right corner) of the spotlight area 50, the user selects the corresponding delete button to selectively select at least one spotlight area 50. Can be deleted. When the last spotlight area 50 is deleted by the delete button, the controller 180 returns to the initial menu screen.

In addition, the user may change detailed settings while the spotlight area 50 is displayed on the menu screen. That is, the user may long-touch a specific border (lower right) of the spotlight area 50 or change the detailed setting in the spotlight menu displayed when an icon indicating that the spotlight mode is currently executed in the indicator area is selected.

7 is a diagram illustrating a menu configuration for setting a spotlight function according to an embodiment of the present invention, and an example of setting a blacklight region.

The user selects the black light menu from the spotlight mode menu, sets the shape, size, and position of the black light area to be displayed on the screen, and then uses the control bar to adjust the brightness of the black light area and the area except the backlight area (the part that is visible). Adjust the brightness individually. In this case, the user may directly check the brightness that changes according to the movement of the adjustment bar. In order to reduce power consumption, the black light area is not powered or is displayed darker than the initial menu screen.

If the user presses a confirmation button after the detailed information on the black light area is set, the controller 180 does not apply power or darkens the power corresponding to the spot light area on the screen. Therefore, the region except for the black light region, that is, the bright portion, looks like the spotlight region 50 described above.

Like the spotlight area 50, the black light area can also be moved, deleted and enlarged / reduced.

8 illustrates an example of performing a spotlight function using a black light area on an application screen.

The user may display a spotlight mode menu as shown in FIG. 3 by selecting a mobile phone setting menu or by long touching a specific position on a screen on which a plurality of menus are displayed. In the spotlight mode menu, the user selects the blacklight menu, sets the shape, size, and position of the blacklight area, and then uses the control bar to adjust the brightness of the blacklight area and the brightness of the area excluding the blacklight area. Adjust each. In this case, the controller 180 allows the user to directly check the brightness and the transparency that change according to the movement of the adjustment bar.

Areas other than the spotlight area (the part that looks dark) include a method of preventing power from being applied and a darker than an initial menu screen in order to reduce power consumption.

If the user selects the OK button after the detailed information on the black light area is set, the controller 180 generates the black light area 51 as shown in FIG. 8. The generated black light region 51 may be moved and adjusted in size by a user's touch operation. Therefore, since the area other than the black light area 51 plays the same role as the spotlight area 50 described above, the user can not only reduce power consumption when executing an application such as KakaoTalk, but also communicate with each other. It can be prevented from being easily exposed to others.

The black light region 51 may be applied in various ways like the spotlight region 50. The black light region 51 may also be moved, deleted and enlarged / reduced. The controller 180 detects the movement, deletion, and enlargement / reduction of the black light region 51 through a sensor and performs a control operation corresponding thereto.

9A to 9C illustrate various application examples of the black light area 51 that can be used in the application screen.

As shown in FIG. 9A, the black light area 51 is fixed while the user receives a conversation from the other party, but when the keypad is selected for input of the conversation, a black pad is displayed at the lower part or the upper part of the bright part. . At this time, the black light area 51 is automatically reduced by the size of the keypad.

As illustrated in FIG. 9B, the black light region 50 may be enlarged or reduced by a user's touch operation, that is, by spreading or pinching two fingers out. In addition, the black light region 50 may be moved by a user's touch and drag operation or may be deleted by a release button displayed during long touch, similar to the spotlight region.

In particular, as shown in FIG. 9C, the color processing may be smoothed by performing a gradation process on the part where the black light area 50 contacts the bright part using a graphic processing technique.

In the present invention, the spotlight area 50 and the black light area 51 are divided and described for convenience of description. However, when any one area is set, the remaining area is automatically determined, and thus the same effect is obtained.

10 is a flowchart illustrating a screen spotlighting method of a mobile terminal according to an embodiment of the present invention.

As illustrated in FIG. 10, a user may execute a spotlight function on the screen of the mobile terminal. The screens are all screens that can be displayed on the mobile terminal, and the display unit 151 displays a screen where a user uses only a part as needed or visually sees only a part of time, for example, a menu screen, a text screen, and an application screen. (S10).

On the screen, the user selects a spotlight mode and sets a spotlight area or a blacklight area in the mode (S11, S12), and at least one of detailed settings for each area, for example, size, brightness, shape, and position. Set (S13). The set detailed information is stored in the memory 160 and may be equally applied when the same screen is displayed later.

After performing the above operation and pressing the OK button, the controller 180 checks whether the spotlight area or the black light area is set (S14). If the spotlight area is set as a result of the check, the controller 180 displays the spotlight area 50 at a predetermined brightness at a predetermined position on the screen according to the set detailed information (S15), and if the black light area is set, the controller 180 sets the set detail. According to the information, the black light region 51 is displayed at a predetermined brightness on a certain position of the screen (S16).

When the spotlight or the blacklight mode is released or the spotlight area 50 or the blacklight area 51 is deleted by a touch operation, the controller 1800 ends all processes of the spotlight function (S18).

As described above, the present invention can reduce unnecessary power consumption by adjusting the brightness, size, and position of a corresponding portion of the screen so that only a desired portion of the screen appears bright by using a spotlight function, and particularly, unwanted information is exposed to others. Can be reduced.

Further, according to an embodiment of the present invention, the above-described method can be implemented as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
