Hereinafter, operation modes of the display unit 151 and the touch pad (not shown) that are related to each other will be described with reference to FIGS. 2A and 2B.

2A and 2B are front views of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be referred to as a so-called " virtual keypad ".

2A illustrates inputting of a touch applied to a virtual keypad through a front surface of a terminal body.

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a virtual keypad 151c is displayed in which a number for inputting a telephone number or the like is displayed. When the virtual keypad 151c is touched, numbers and the like corresponding to the touched virtual keypad are displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

2B shows a touch input to the virtual keypad through the rear surface of the terminal body. FIG. 2A shows a case where the terminal body is vertically arranged, and FIG. 3B shows a case where the terminal body is arranged horizontally. The display unit 151 may be configured to convert the output screen according to the arrangement direction of the terminal body.

2B shows that the text input mode is activated in the portable terminal. The display unit 151 displays an output window 151a 'and an input window 151b'. The input window 151b 'may have a plurality of virtual keypads 151c' displayed with at least one of characters, symbols, and numbers. The virtual keypads 151c 'may be arranged in the form of a QWERTY key.

When the virtual keypads 151c 'are touched through the touchpad (not shown), letters, numbers, symbols, etc. corresponding to the touched virtual keypad are displayed on the output window 151a'. As described above, the touch input through the touch pad is advantageous in that the virtual keypad 151c 'can be prevented from being hidden by the finger when the touch is input, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad are formed transparently, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

In addition to the input method described in the above embodiments, the display unit 151 or the touch pad may be configured to receive touch input by scrolling. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad. Further, when the finger is moved on the display unit 151 or the touch pad, the path along which the finger moves may be visually displayed on the display unit 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

3 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 3, when a pointer such as a user's finger, a pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

In FIG. 3, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity depth and proximity position of the pointer, and perform various operation control according to the various input signals.

It is assumed that the mobile terminal referred to herein may include at least one of the components shown in FIG.

At this time, the user proximity touch operation is performed for a specific object, and the specific object selected by the user proximity touch operation can be displayed to be distinguished.

Further, the mobile terminal can make the selection range of the specific object different according to the proximity touch distance. For example, the shorter the proximity touch distance, the smaller the number or the area of objects to be selected.

5C shows a state in which a selection operation of a user is input using a camera.

Here, the camera may be the camera 121 shown in FIG. 1 and separately provided for the selection operation.

In addition, the camera 133 and the display unit 151 may be disposed on the same plane in order to allow the user to input a selection operation for a specific object while confirming the selected specific object corresponding thereto.

FIG. 5D shows a state in which the user's selection operation is input using the wind sensor.

Here, the wind sensing sensor may be provided in a microphone / earphone or a speaker, and when the user blows wind on the microphone / earphone / speaker, the strength or the end of the wind can be recognized. Particularly, the wind sensor can use only the portion where noise is removed from the wind inputted by the user.

Referring to FIG. 5D, the wind sensor 134 is provided at the lower end of the display unit 151, and recognizes the selection operation corresponding to the wind detected by the user.

Here, the screen effect processing means editing an image portion corresponding to a specific object. For example, the image effect processing includes at least one of zooming, shaking, position shifting, shape transformation, and color change for a specific object can do.

In the performing step S430, the mobile terminal 100 may perform different screen effect processing according to the type of selection operation for a specific object. For example, when a touch drag operation from a specific object to another point in the first image is input as a selection operation, the specific object can be moved to another point.
