Referring to FIG. 3, a second camera module 121-2 may be additionally mounted on the rear surface of the second rear case 100B-2 of the second body 100B. The second camera module 121-2 may have a photographing direction substantially opposite to that of the first camera module 121-1 (see FIG. 1), and may have different pixels from the first camera module.

For example, the first camera module 121-1 has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the second camera module 121-2 is a general subject. It can be configured to have high pixels because it is often not taken and sent immediately.

The flash 121-3 and the mirror 121-4 may be further disposed adjacent to the second camera module 121-2. The flash 121-3 illuminates the light toward the subject when the subject is photographed by the second camera module 121-2. The mirror 121-4 allows the user to see his / her own face or the like when the user wants to photograph himself (self photographing) using the second camera module 121-2.

The second sound output module 152-2 may be further disposed on the second rear case 100B-2.

The second sound output module 152-2 may implement a stereo function together with the first sound output module 152-1 (see FIG. 2), and may be used for a call in a speakerphone mode.

In addition, an antenna 111-1 for receiving a broadcast signal may be disposed on one side of the second rear case 100B-2 in addition to an antenna for a call. The antenna 111-1 may be installed to be pulled out of the second body 100B and 2.

A portion of the slide module 100C for slidably coupling the first body 100A and the second body 100B to the first rear case 100A-2 side of the first body 100A is disposed.

The other part of the slide module 100C may be disposed on the side of the second front case 100B-1 of the second body 100B and may not be exposed to the outside as shown in the drawing.

In the above description, the second camera module 121-2 is disposed on the second body 100B, but is not necessarily limited thereto.

For example, at least one of the elements 111-1, 121-2 to 121-3, and 152-2 described as disposed on the second rear case 100B-2, such as the second camera module 121-2. At least one may be mounted to the first body 100A, mainly the first rear case 100A-2. In such a case, there is an advantage that the configuration (s) arranged in the first rear case 100A-2 in the closed state are protected by the second body 100B. Furthermore, even if the second camera module 121-2 is not separately provided, the first camera module 121-1 is formed to be rotatable so that shooting can be performed up to the shooting direction of the second camera module 121-2. It may be configured.

The portable terminal according to an embodiment of the present invention may perform a road guidance function. One such example is shown in FIG. 4.

As shown, the display module 151 displays a map displaying the current location. Using the displayed map, the user can easily find the destination.

In addition, the portable terminal capable of performing the road guidance function may be implemented in a navigation form attached to the vehicle. One such example is shown in FIG. 5.

Meanwhile, the portable terminal 100 according to an embodiment of the present invention may use specific information to perform a specific function. The specific information may be stored in the portable terminal, or may be received by performing data communication with a server, as shown in FIG. 6.

On the other hand, the portable terminal 100 according to an embodiment of the present invention performs the road guidance function as described above. If the mobile terminal 100 is located in the GPS shadowed area, it may not be possible to properly receive location information. The GPS shaded area refers to an area where the location information cannot be properly received due to the obstacles in receiving the location information. The GPS shadowed area may include a multipath area, which is an area where signals arrive in multiple paths and signal reception is disturbed.

Next, a method of adjusting the current position in the mobile terminal 100 according to an embodiment of the present invention will be described in more detail.

7 is a flowchart illustrating a method of adjusting a current position in the mobile terminal 100 according to an embodiment of the present invention.

While driving on the road, the mobile terminal 100 may enter the GPS shadow area (S10). If a user enters a GPS shadow area, the user may be notified of the entry. The GPS shadowed area information may be stored in the mobile terminal or provided from a specific server (shown in FIG. 6). In addition, the information on the GPS shadow linear region may be provided in the form of a Transport Protocol Experts Group (TEPG).

8 is a state diagram illustrating a screen displaying a pop-up window for notifying the entry of a GPS shadow area when the portable terminal according to an embodiment of the present invention enters the GPS shadow area.

As shown, by displaying a pop-up window 803 indicating that the GPS shadow area has been entered, a user may be able to confirm that his or her current location is correctly displayed. In this case, the current location of the user may be displayed using the icon 801.

In addition, the mobile terminal 100 according to an embodiment of the present invention may predict the entry of the GPS shadow area. For example, the display may indicate the entry of the GPS shaded area by displaying the phrase "enter 1km shaded area (not shown)". Of course, the fact that the GPS shadow area entry and the GPS shadow area entry notice may be notified to the user through the audio signal or the vibration output.

When the user enters the GPS shadowed area, the user may check whether the display indicating the current location corresponds to the actual driving road (S20). If the current location indication matches the road currently being driven, the road guide may be performed based on the displayed current location.

On the other hand, when the display indicating the current position and the actual traveling road do not coincide, correction of the display indicating the current position is necessary. In this case, the user may adjust the current position by moving the display indicating the current position (S20, S30). This will be described in more detail. Of course, an error may occur in the display of the current location even in areas where the mobile terminal does not indicate the GPS shadow area.

9 is a diagram illustrating a state in which a current position is corrected in a mobile terminal according to an embodiment of the present invention.

FIG. 9A illustrates a case where an icon 801 indicating a current driving road does not match. The user may visually check whether or not the actual driving road and the icon 801 are correctly matched. For example, the user may know how many times the road is currently driven through a milestone or the like. By the way, when the icon 801 displayed on the road guidance screen is not displayed on the road which is actually driving, the user may think that an error has occurred in the current location display.

9B illustrates a method of correcting the current position by moving an icon when an error occurs in the current position display. As illustrated, when the road actually being driven is a darkly displayed road indicated by the arrow 901, the user may move the icon 801 in the direction of the arrow 901 through the manipulation of the manipulation unit 130.

There may be various methods of moving the icon 801 to match the actual road. For example, the display unit 151 may be moved using a direction key provided in the manipulation unit 130, or when the display module 151 displaying the road guidance screen is configured as a touch screen, the icon 801 may be dragged. You can move it.

As described above, the icon 801 moved through the manipulation of the user manipulation unit 130 is displayed to be matched with the road that is actually driving (FIG. 9C).

When the icon 801 is corrected to match the actual road, the controller 180 performs road guidance based on the icon whose position is corrected (S40). In this case, the current position correction algorithm may be performed by weighting the road selected by the user.

In addition, the portable terminal 100 according to an embodiment of the present invention may store an area where the current position is corrected by moving the icon 801 as described above. For example, the area where the current position is corrected through the movement of the icon 801 may be set as the GPS sound region.

10 shows such an example. As shown, when the current position is corrected through the movement of the icon 801, a popup window 1001 is displayed allowing the user to set the GPS shaded region for the region whose current position is corrected. By setting the GPS shaded area in the region where the current position is corrected, the user may prevent an error in the display of the current position when driving the region where the current position is corrected later.

On the other hand, the error of the display of the current position of the portable terminal according to an embodiment of the present invention may also occur in an area where several roads are layered, such as ground / underground roads.

11 is a flowchart illustrating still another method for adjusting a current position in a mobile terminal 100 according to an embodiment of the present invention.

While driving on the road, the mobile terminal 100 may enter a location where a plurality of roads having different altitudes exist (S110). For example, the user may enter a place where the ground / underground roadway and the like exist together, or may enter a place where the ground / highway roadway and the like exist together.

When the portable terminal 100 is located where a plurality of roads having different altitudes exist, the mobile terminal 100 may display a screen displaying a list of the plurality of roads (S120). The screen on which the list of the plurality of roads is displayed may be displayed at the same time as the entry of the plurality of roads, or may be displayed by manipulation of the manipulation unit 130 of the user.

Meanwhile, according to an exemplary embodiment of the present invention, when the mobile terminal 100 enters a place where the plurality of roads exist, the mobile terminal 100 may inform the user of the entry to the place. For example, upon entering a place where a plurality of layers of roads exist as described above, the place may be automatically notified of the entry of the place, or a specific key signal may be input to notify the entry of the place. When entering the above places, there may be a variety of ways to inform the user of the fact. For example, a vibration output, an audio signal output, a video signal output, or the like can be used.

In addition, the information on the location of the plurality of roads layered may be stored in the mobile terminal 100, or may be provided from a specific server. In addition, information on a place where a plurality of layers of roads exist may be provided in the form of a Transport Protocol Experts Group (TEPG).

As described above, the mobile terminal 100 may be located on any one of the plurality of roads. However, since the plurality of roads exist in layers, the mobile terminal 100 may not recognize exactly which road it is located in. In this case, the user may receive a more accurate road guide by accurately selecting a road that is actually driving. That is, the user may select a road that is actually driving from among the plurality of displayed roads (S130).

Then, the controller 180 can perform a road guide based on the selected road (S140). That is, the mobile terminal 100 may recognize that the mobile terminal 100 is located on the selected road and perform road guidance (S140).

Next, a process of adjusting the current position of the mobile terminal 100 by the method illustrated in FIG. 11 will be described in more detail.

12 is a diagram illustrating a state in which a current position is corrected in a mobile terminal according to an embodiment of the present invention.

FIG. 12A is a diagram illustrating one road on a map, but a plurality of roads traveling on a road having an upper and lower layer.
