In the foregoing, the configuration of the mobile terminal 100 according to the present invention has been described with reference to FIG. 1 to FIG. Hereinafter, a mobile terminal capable of efficiently capturing a screen image of a size larger than an output screen of a display unit according to a preferred embodiment of the present invention and an operation method thereof will be described in detail.

4 is a flowchart illustrating an operation of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 4A, the controller 180 displays a predetermined operation screen on the display unit 151 according to a user command (S410). At this time, the operation screen may be any screen that can be output from the mobile terminal 100, but it is not limited thereto. For example, the operation screen includes a home screen, a main menu screen, a setting screen, a broadcast screen, a web page screen, an application execution screen, a list screen, and the like. Hereinafter, in the present embodiment, for the sake of explanation, it is assumed that the operation screen is a web page screen.

When a user of the mobile terminal 100 views an image of a web page displayed on the display unit 151 and needs an image corresponding to all or a part of the content of a specific web page screen, Technology.

That is, the control unit switches the operation mode of the mobile terminal to the screen capture mode in response to the predetermined user input (S415). The predetermined user input may be a user input for operating a predetermined hot key or a user input for simultaneously operating at least two predetermined hard keys or soft keys, And may be a user input that touches the screen capture menu displayed in the area.

Upon entering the screen capture mode, the controller 180 activates a capture window for setting a screen capture area and displays the activated capture window on the output screen of the display unit 151. [ At this time, it is preferable to set the capture area so that the entire output screen of the display unit 151 is captured, and the position and size of the initial capture area can be changed according to the user setting and the design of the manufacturer .

In addition, it is preferable that the capture window is displayed in the same rectangular shape as that of the display unit 151, and that the shape of the capture window may be changed according to the user setting. In addition, the capture window may include a status bar area (i.e., a region in which icons representing status information of the mobile terminal are displayed) displayed at the top of the display unit 151 according to a user setting or a manufacturer's design May or may not be included.

When the capture window is displayed on the display unit 151, the controller 180 determines whether the user's touch and drag input is received through the boundary region of the capture window (S425). In other words, the control unit 180 confirms whether a boundary region of the capture window is touched by the user, and then an input for dragging in the inside or outside direction of the capture window is received.

If the user's touch and drag input is received through the boundary of the capture window, the controller 180 changes the position and size of the capture window according to the direction of the received touch and drag input (S430). Through the change of the capture window, the mobile terminal 100 can display not only the content corresponding to the entire area of the web page screen displayed on the output screen of the display unit 151, but also the content corresponding to the partial area of the web page screen Screen capture can also be performed.

If it is determined that the user's touch and drag input is not received through the boundary of the capture window, the control unit 180 continues to display the initially set capture window on the display unit 151.

Referring to FIG. 4B, the controller 180 controls the display unit 151 to capture a screen image of a size larger than an output screen of the display unit 151, It is checked whether user input is received (S435).

The first user input may include an input for double-touching the capture window area, an input for long-touching the capture window area for a predetermined time, and an input for flicking the capture window area in a predetermined direction, Input. Also, the first user input may be a user input for selecting a predetermined hard key or a soft key.

If it is determined in step 435 that the first user input for entering the scroll capture mode is not received, the control unit 180 determines whether a third user input for performing a normal screen capture is received S440). Herein, the third user input is a user input distinguished from the first user input. The input is a double-touch input to the capture window area. The input and capture window areas are long-touched for a predetermined time in a predetermined direction And may be any one of the inputs that flicking. The third user input may also be a user input for selecting a predetermined hard key or a soft key.

If it is determined in step 440 that a third user input for performing a normal screen capture is received, the controller 180 captures a screen image displayed in the capture window area in step S460. On the other hand, if it is determined that the third user input is not received, the controller 180 proceeds to step 420 and continues to display the capture window on the web page screen.

As a result of the checking in step 435, when the first user input is received, the control unit 180 displays the scroll capture mode (step < RTI ID = 0.0 > scroll capture mode (S445). At this time, the control unit 180 may display a notification window for informing the user that the user has entered the scroll capture mode, for a predetermined period of time and then disappear.

In this scroll capture mode, when a user's touch and drag input (i.e., the user's scroll operation) is received through the capture window area, the control unit 180 scrolls the web page screen according to the direction of the touch and drag input S450). At the same time, the control unit determines the area of the web page screen passing through the capture window area through the screen scroll operation. Accordingly, in the scroll capture mode, the mobile terminal 100 can easily display a predetermined screen capture area for a web page screen having a size larger than the output screen of the display unit 151, based on the scroll operation input from the user .

In another embodiment, when an input for touching and dragging the capture window region is received within a predetermined time after the initial capture window is displayed, the web page screen may be scrolled simultaneously with the entry of the scroll capture mode.

Thereafter, the controller 180 determines whether a second user input for ending the scroll capture mode is received (S455). Here, the second user input may include an input for double-touching the capture window area, an input for long-touching the capture window area for a predetermined time, and an input for flicking the capture window area in a predetermined direction, Input. Also, the second user input may be a user input for selecting a predetermined hard key or soft key. Also, the second user input may be the same user input as the first user input, or a user input different from the first user input.

If it is determined in step 455 that the second user input for ending the scroll capture mode is not received, the controller 180 moves to step 450 and continues to operate in the scroll capture mode. If it is determined in operation 455 that the second user input is received, the control unit 180 automatically captures an image corresponding to the capture area set by the user after the scroll capture mode is terminated in operation S460.
