The camera 121 of the second body 205 has a photographing direction which is substantially opposite to that of the camera 121 of the first body 200 and a different pixel from the camera 121 of the first body 200 Lt; / RTI >

For example, the camera 121 of the first body 200 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit it to the other party, It is preferable to have a high pixel since the subject is often photographed and not immediately transferred.

A flash 250 and a mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 illuminates the subject when the subject of the subject is photographed by the camera 121 of the second body 205.

In the above description, the second camera 121 or the like is disposed on the second body 205, but the present invention is not limited thereto.

For example, at least one of the configurations 260, 121 to 250, and 152 described as being disposed in the second rear case 235, such as the camera 121 of the second body, It is also possible that the first rear case 225 is mounted to the rear case 225. In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state is protected by the second body 205. Further, even if the camera 121 of the second body is not separately provided, the camera 121 of the first body may be configured to be rotatable so that the camera 121 of the second body can be photographed up to the photographing direction .

The terminal 100 shown in Figs. 1 to 3 is operable in a communication system capable of transmitting data through a frame or a packet, including a wired / wireless communication system and a satellite-based communication system .

Hereinafter, a communication system capable of operating a terminal according to the present invention will be described with reference to FIG.

The communication system may use different air interfaces and / or physical layers. For example, wireless interfaces that can be used by communication systems include, but are not limited to, Frequency Division Multiple Access ('FDMA'), Time Division Multiple Access ('TDMA'), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE)), Global System for Mobile Communications (GSM) . Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, the present invention is applicable to all communication systems including CDMA wireless communication systems.

4, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BSs) 270, and base station controllers (BSCs) 275 , And a mobile switching center ('MSC') 280. MSC 280 is configured to be coupled to a Public Switched Telephone Network (" PSTN ") 290, and is also configured to be coupled to BSCs 275. BSCs 275 may be coupled in pairs with BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial from BS 270. [ In addition, each sector may include two or more antennas of various types. Each BS 270 may be configured to support a plurality of frequency assignments and each of the plurality of frequency assignments has a specific spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. BS 270 may be referred to as a Base Station Transceiver Subsystem (BTSs). In this case, the word "base station" may be referred to as a combination of one BSC 275 and at least one BS 270. [ The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

In addition, FIG. 4 illustrates several Global Positioning System ('GPS') satellites 300. The satellites 300 help to locate at least one of the plurality of terminals 100. Although two satellites are shown in Figure 4, useful location information may be obtained by two or more satellites. The location information module 115 shown in FIG. 1 cooperates with satellites 300 to obtain desired location information. Here, you can track your location using all of the technologies that can track your location, as well as your GPS tracking technology. Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Among the typical operations of a wireless communication system, the BS 270 receives a reverse link signal from the various terminals 100. At this time, the terminals 100 are in the process of connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

A method for changing a keypad display according to a keypad setting change in a mobile terminal according to an embodiment of the present invention will now be described. The mobile terminal 100 according to the present embodiment can change the key arrangement and the display key of the keypad when the display position and size of the keypad are changed in relation to touch or proximity.

A touch refers to a state in which a pointing device contacts a display screen. Here, the positioning tool is a tool for specifying a specific point on a display screen, and includes a user's finger, a stylus, a light pen, and the like.

The proximity means a state in which the positioning tool does not touch the display screen and is a certain distance away from the screen.

That is, the mobile terminal according to an exemplary embodiment of the present invention can sense the touch and the proximity through the sensing unit 140. The sensing unit 140 may include a touch sensor for sensing a touch and / or a proximity sensor for sensing proximity.

The proximity sensor senses the proximity sensor when it approaches within a predetermined distance from the screen, and generates and outputs a corresponding sensing signal. That is, the proximity sensor can detect and output the distance (proximity distance) between the positioning tool and the sensor based on the capacitance that varies according to the approach distance of the positioning tool. In addition, the proximity sensor may output positional information (coordinate value) of a specific point vertically corresponding to the positioning tool when the positioning tool approaches.

In addition, the proximity sensor may sense a speed at which the positioning tool approaches the display screen (proximate speed) or a speed at which the positioning tool moves away from the display screen (proximate speed). In addition, the proximity sensor may detect proximity drag in which the proximity point moves while the positioning tool is located within a predetermined distance from the display screen.

Although the capacitive proximity sensor is described in this specification as an example, various types of proximity sensors may be used.

The touch sensor outputs position information (coordinate value) of a corresponding point at which the touch of the positioning tool is sensed. Such a touch sensor can be realized by various types of touch pads such as an electrostatic type and a static pressure type. In addition, the touch pad may be formed as a touch screen in a mutual layer structure with the display unit 151, so that the display unit 151 can be used not only as a display device but also as an input device.

The touch sensor can sense the drag distance, drag direction, drag speed, flick direction, and so on. The drag refers to a state in which the touch point moves (changes) while the touch is maintained.

5 is a diagram illustrating an example in which touch and proximity are sensed.

As shown, the sensing unit 140 can detect proximity only when the positioning tool is located within a predetermined distance D from the display unit 151 (a). Here, the predetermined distance D is a proximity sensing area in which the proximity sensor can sense the approach of the positioning tool. Accordingly, when the positioning tool (e.g., user finger) is positioned within the proximity sensing area, the sensing unit 140 can sense the approach of the positioning tool.

On the other hand, if the positioning tool is located in a space outside the proximity sensing area, the sensing unit 140 can not sense the positioning tool. That is, when the positioning tool existing in the proximity sensing area is out of the proximity sensing area, the controller 180 recognizes that the proximity is released.

In addition, the sensing unit 140 may sense a touch on the screen of the display unit 151. FIG. That is, when the position specifying tool touches the screen of the display unit 151, the sensing unit 140 can detect the touch of the position specifying tool (c).

On the other hand, if the positioning tool is separated from the display unit 151, the sensing unit 140 can not detect the positioning tool. Accordingly, the mobile terminal 100 recognizes that the touch is released.

When the keypad setting such as the keypad display position and / or the keypad size is changed by an input such as proximity and / or touch, the control unit 180 changes the keypad display based on the changed setting. That is, the controller 180 may change the key arrangement of the keypad, the shape of the keypad, the display keys, the key arrangement, and the like.

6 is a flowchart illustrating a keypad display method of a mobile terminal according to an embodiment of the present invention. This embodiment describes changing the keypad display in accordance with the change of the display position of the keypad.

First, the sensing unit 140 may sense the touch on the screen of the display unit (S101). That is, when the position designation tool is touched to one point of the keypad displayed on the display unit 151, the sensing unit 140 senses the touch of the position designation tool.

The controller 180 determines whether the sensing signal transmitted from the sensing unit 140 is a keypad setting change command (S103). In order to distinguish whether the sensed touch is for data input or for changing the keypad setting, the controller 180 recognizes the touchpad as a keypad setting change command if the touch is maintained for a predetermined time (2-3 seconds) And recognizing the touch as a data input when the holding time is less than a predetermined time.

In this embodiment, the input of the keypad setting change command and the data input are distinguished by using the long touch, but it is possible to distinguish the input of the setting change command and the data input by using proximity sensing. For example, the mobile terminal 100 recognizes a command for data input when the touch is sensed, and recognizes the command as a keypad setting change command when proximity is sensed.

After the keypad setting change command is input, the controller 180 determines whether the display position of the keypad is changed (S105). That is, when the dragging is performed, the controller 180 grasps the drag distance and direction through the sensing unit 140, and changes the display position of the keypad according to the detected drag distance and direction. Here, if the drag distance is equal to or greater than a predetermined distance, the controller 180 recognizes the command as a command for changing the keypad display position.

If it is determined that the display position of the keypad is changed, the controller 180 may change the keypad display according to the changed keypad display position (S107). That is, when the keypad display position is changed, the controller 180 can change the key arrangement and the shape of the keypad according to the changed display position.

If it is determined in step S103 that the sensing signal is not a keypad setting change command, the controller 180 may recognize the key selection corresponding to the sensed touch point in step S115. Accordingly, the information allocated to the selected key may be received as data and displayed on the display unit 151 or a specific function assigned to the selected key may be executed.

FIG. 7 is an exemplary view showing a display position at which a keypad can be displayed in a mobile terminal according to the embodiment of FIG. 6. FIG.

As shown in the drawing, the mobile terminal 100 related to the present invention can divide a position where the keypad can be displayed into four areas A1 to A4. That is, the mobile terminal 100 may place a keypad on any one of the upper end A1, the lower end A2, the left end A3, and the right end A4 of the display screen according to user input. Here, the dividing line for dividing the area may be shown so that the user can recognize a changeable keypad display position.

For example, when dragging is performed in the upward direction, the mobile terminal 100 places the keypad at the top A1 of the display screen. Also, when dragging is performed in the left direction, the mobile terminal 100 displays a keypad on the 'A3' area of the display screen. Also, if the dragging is performed in the right direction, the mobile terminal 100 changes the keypad display position to the 'A4' area of the display screen. Also, if the dragging is performed in the downward direction, the controller 180 changes the keypad display position to the area 'A1'.

8 is an exemplary diagram illustrating an example associated with the embodiment of FIG.

As shown in FIG. 8A, when a user's finger is touched at one point on the keypad displayed on the display unit 151, the sensing unit 140 senses the touch of the user's finger. If the sensed touch is maintained for a predetermined time or longer, the control unit 180 recognizes the command as a command for changing the keypad setting. For example, when the time for which the touch is maintained exceeds 3 seconds, the control unit 180 recognizes the touch input as a command for changing the keypad setting. If the touch holding time is less than 3 seconds, .

Then, when the user's finger moves from one point to another point, the controller 180 can change the keypad display position according to the moving direction. For example, when the user's finger is dragged upward, the control unit 180 changes the keypad display position to the area " A1 ". At this time, the controller 180 checks whether the change of the keypad display is required according to the change of the keypad display position. If the confirmation of the keypad display is not required, only the display position of the keypad is changed.

In addition, the control unit 180 can change the position (information display position) where the input data and various information are displayed as the keypad display position is changed.

Referring to FIG. 8B, when a user's finger is touched on the keypad displayed at the bottom of the screen of the display unit 151, the sensing unit 140 senses the user's finger and informs the control unit 180 of the sensing result. After the touch is detected, if the drag operation is performed to the left, the controller 180 grasps the dragged direction. Then, the control unit 180 changes the keypad display position to the area 'A3' based on the detected drag direction.

When the setting of the keypad display position is completed, the controller 180 determines whether the keypad display needs to be changed. If it is determined that the keypad display needs to be changed, the controller 180 may change the keypad shape and key arrangement. That is, when the shape of the keypad is different from the shape of the 'A3' area where the keypad is located, the controller 180 changes the shape of the keypad to be the same as the shape of the 'A3' area. In addition, the controller 180 may change the key arrangement according to the modified keypad pattern.

9 is a flowchart illustrating a keypad display method of a mobile terminal according to another embodiment of the present invention. This embodiment describes changing the keypad display according to the size change of the keypad.

The sensing unit 140 may sense a touch on the screen of the display unit (S201). That is, the sensing unit 140 senses the touch of the positioning tool when the positioning tool touches one of the edges (borders) of the keypad displayed on the display unit 151.

The control unit 180 determines whether the sensing signal transmitted from the sensing unit 140 is an input for changing the keypad setting (S203). That is, when the sensed touch point is the edge of the keypad, the controller 180 can recognize the input for changing the size of the keypad.

After the touch is detected, if the drag operation is performed, the controller 180 may change the size of the keypad based on the detected drag distance (S205). The drag distance means a straight line distance between the start point and the end point of the drag. For example, when any one of the sides of the keypad is moved by dragging, the controller 180 may enlarge or reduce the size of the keypad by moving corresponding sides of the keypad by the drag distance.

If one of the corners of the keypad is moved by dragging, the control unit 180 may enlarge or reduce the size of the keypad by changing the width and height of the keypad.

When the size of the keypad is changed, the controller 180 may change the keypad display based on the size of the changed keypad (S207). That is, when the size of the keypad is enlarged or reduced, the controller 180 can change the key arrangement, shape, display key, and the like constituting the keypad according to the changed size.

10 is an exemplary view showing an example related to the embodiment of FIG.

10A, when a user's finger is touched at one point on the top of the keypad during message creation, the sensing unit 140 senses it and notifies the control unit 180 of the sensed result. After the touch is sensed, if the user's finger moves from one point to another point, the controller 180 moves the top of the keypad by the distance moved through the drag. At this time, if the size of the keypad becomes smaller than a predetermined size, the controller 180 can change the key arrangement and the display key of the keypad.

10B, when the user's finger approaches one point of the right end of the keypad displayed on the display unit 151, the sensing unit 140 senses approach of the user's finger and informs the control unit 180 of the approach. Then, when the drag operation is performed in the left direction, the controller 180 can change the size of the keypad by moving the right side of the keypad by the drag distance. Here, if the size of the keypad becomes smaller than a predetermined size, the controller 180 may change the key arrangement and display key of the keypad.

As shown in FIG. 10C, when the position specifying tool is touched to the upper right corner of the keypad displayed on the display unit 151, the sensing unit 140 can sense the touch. After the detected touch is maintained for a predetermined time (for example, 2 seconds), if the proximity drag is detected, the controller 180 moves the corner of the keypad according to the proximity drag. For example, when the proximity drag is performed in the left lower direction, the controller 180 moves the upper right corner of the keypad in the left lower direction by the drag distance. In addition, the controller 180 may change the size of the keypad according to the movement of the corner of the keypad, and may change the key arrangement and the display key of the keypad according to the changed keypad size.

11 is a flowchart illustrating a keypad display method of a mobile terminal according to another embodiment of the present invention. The present embodiment explains the control of the keypad display according to the state in which the terminal is placed.

Referring to FIG. 5, the sensing unit 140 may sense movement of the terminal, such as tilting or rotating, through an acceleration sensor and / or a tilt sensor (S301). When the movement of the terminal is sensed, the controller 180 grasps the state of the terminal based on the sensing signal transmitted from the sensing unit 140. Here, the laying state of the terminal may be divided into a landscape view and a portrait view.

Then, the controller 180 determines whether the detected state of the terminal is inconsistent with the previous state (S303, S305). That is, the control unit 180 determines whether the state of the terminal is changed.

If it is determined in step S307 that the status of the terminal is changed, the controller 180 changes the keypad display according to the changed status of the terminal. That is, the control unit 180 can change the key arrangement, shape, display key, and the like of the keypad based on the state of the terminal.

12 is an exemplary view showing an example related to the embodiment of FIG.

As shown in FIG. 12, when the terminal is rotated in the counterclockwise direction by 90 degrees while the terminal is being placed in the portrait view, the sensing unit 140 senses the rotation of the terminal.

After the rotation of the terminal is sensed, the controller 180 grasps the state of the terminal based on the sensing signal generated from the sensing unit 140. As a result, if the state in which the terminal is laid out is recognized as a landscape view, the controller 180 changes the keypad corresponding to the laid-in state and displays the changed keypad. For example, when the terminal is rotated in a state where the keypad of the 4X3 array is displayed, the controller 180 senses the keypad through the sensing unit 140, 2x6 array keypad. In other words, the mobile terminal 100 related to the present embodiment can change the key arrangement and shape of the keypad according to the laying state of the terminal.
