       FIG. 1  is a block diagram of a mobile terminal  100  in accordance with one exemplary embodiment. 
     The mobile terminal  100  may comprise components, such as a wireless communication unit  110 , an Audio/Video (A/V) input unit  120 , a user input unit  130 , a sensing unit  140 , an output unit  150 , a memory  160 , an interface unit  170 , a controller  180 , a power supply  190  and the like.  FIG. 1  shows the mobile terminal  100  having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented. 
     Hereinafter, each component  110  to  190  is described in sequence. 
     The wireless communication unit  110  may typically include one or more modules which permit wireless communications between the mobile terminal  100  and a wireless communication system or between the mobile terminal  100  and a network within which the mobile terminal  100  is located. For example, the wireless communication unit  110  may include at least one of a broadcast receiving module  111 , a mobile communication module  112 , a wireless Internet module  113 , a short-range communication module  114 , a location information module  115  and the like. 
     The broadcast receiving module  111  receives a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. 
     The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast managing entity may indicate a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which receives a pre-generated broadcast signal and/or broadcast associated information and sends them to the mobile terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. The broadcast signal may further include a data broadcast signal combined with a TV or radio broadcast signal. 
     Examples of broadcast associated information may include information associated with a broadcast channel, a broadcast program, a broadcast service provider, and the like. The broadcast associated information may be provided via a mobile communication network, and received by the mobile communication module  112 . 
     The broadcast associated information may be implemented in various formats. For instance, broadcast associated information may include Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), Electronic Service Guide (ESG) of Digital Video Broadcast-Handheld (DVB-H), and the like. 
     The broadcast receiving module  111  may be configured to receive digital broadcast signals transmitted from various types of broadcast systems. Such broadcast systems may include Digital Multimedia Broadcasting-Terrestrial (DMB-T), Digital Multimedia Broadcasting-Satellite (DMB-S), Media Forward Link Only (MediaFLO), Digital Video Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T) and the like. The broadcast receiving module  111  may be configured to be suitable for every broadcast system transmitting broadcast signals as well as the digital broadcasting systems. 
     Broadcast signals and/or broadcast associated information received via the broadcast receiving module  111  may be stored in a suitable device, such as a memory  160 . 
     The mobile communication module  112  transmits/receives wireless signals to/from at least one of network entities (e.g., base station, an external mobile terminal, a server, etc.) on a mobile communication network. Here, the wireless signals may include audio call signal, video (telephony) call signal, or various formats of data according to transmission/reception of text/multimedia messages. 
     The mobile communication module  112  may implement a video call mode and a voice call mode. The video call mode indicates a state of calling with watching a callee&#39;s image. The voice call mode indicates a state of calling without watching the callee&#39;s image. The wireless communication module  112  may transmit and receive at least one of voice and image in order to implement the video call mode and the voice call mode. 
     The wireless Internet module  113  supports wireless Internet access for the mobile terminal. This module may be internally or externally coupled to the mobile terminal  100 . Examples of such wireless Internet access may include Wireless LAN (WLAN) (Wi-Fi), Wireless Broadband (Wibro), Worldwide Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA) and the like. 
     The short-range communication module  114  denotes a module for short-range communications. Suitable technologies for implementing this module may include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee™, Near Field Communication (NFC) and the like. 
     The location information module  115  denotes a module for detecting or calculating a position of a mobile terminal. An example of the location information module  115  may include a Global Position System (GPS) module or a wireless fidelity (WiFi) module. 
     Still referring to  FIG. 1 , the A/V input unit  120  is configured to provide audio or video signal input to the mobile terminal. The A/V input unit  120  may include a camera  121  and a microphone  122 . The camera  121  receives and processes image frames of still pictures or video obtained by image sensors in a video call mode or a capturing mode. The processed image frames may be displayed on a display unit  151 . 
     The image frames processed by the camera  121  may be stored in the memory  160  or transmitted to the exterior via the wireless communication unit  110 . Also, user&#39;s position information and the like may be calculated from the image frames acquired by the camera  121 . Two or more cameras  121  may be provided according to the configuration of the mobile terminal. 
     The microphone  122  may receive an external audio signal while the mobile terminal is in a particular mode, such as a phone call mode, a recording mode, a voice recognition mode, or the like. This audio signal is processed into digital data. The processed digital data is converted for output into a format transmittable to a mobile communication base station via the mobile communication module  112  in case of the phone call mode. The microphone  122  may include assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal. 
     The user input unit  130  may generate input data input by a user to control the operation of the mobile terminal. The user input unit  130  may include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch and the like. 
     The sensing unit  140  provides status measurements of various aspects of the mobile terminal. For instance, the sensing unit  140  may detect an open/close status of the mobile terminal, a change in a location of the mobile terminal  100 , a presence or absence of user contact with the mobile terminal  100 , the location of the mobile terminal  100 , acceleration/deceleration of the mobile terminal  100 , and the like, so as to generate a sensing signal for controlling the operation of the mobile terminal  100 . For example, regarding a slide-type mobile terminal, the sensing unit  140  may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include sensing functions, such as the sensing unit  140  sensing the presence or absence of power provided by the power supply  190 , the presence or absence of a coupling or other connection between the interface unit  170  and an external device. 
     The output unit  150  is configured to output an audio signal, a video signal or a tactile signal. The output unit  150  may include a display unit  151 , an audio output module  153 , an alarm unit  154  and a haptic module  155 . 
     The display unit  151  may output information processed in the mobile terminal  100 . For example, when the mobile terminal is operating in a phone call mode, the display unit  151  will provide a User Interface (UI) or a Graphic User Interface (GUI), which includes information associated with the call. As another example, if the mobile terminal is in a video call mode or a capturing mode, the display unit  151  may additionally or alternatively display images captured and/or received, UI, or GUI. 
     The display unit  151  may be implemented using, for example, at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-Liquid Crystal Display (TFT-LCD), an Organic Light-Emitting Diode (OLED), a flexible display, a three-dimensional (3D) display, an e-ink display or the like. 
     Some of such displays  151  may be implemented as a transparent type or an optical transparent type through which the exterior is visible, which is referred to as ‘transparent display’. A representative example of the transparent display may include a Transparent OLED (TOLED), and the like. 
     The display unit  151  may also be implemented as a stereoscopic display unit  152  for displaying stereoscopic images. 
     Here, the stereoscopic image may be a three-dimensional (3D) stereoscopic image, and the 3D stereoscopic image is an image refers to an image making a viewer feel that a gradual depth and reality of an object on a monitor or a screen is the same as a reality space. A 3D stereoscopic image is implemented by using binocular disparity. Binocular disparity refers to disparity made by the positions of two eyes. When two eyes view different 2D images, the images are transferred to the brain through the retina and combined in the brain to provide the perception of depth and reality sense. 
     The stereoscopic display unit  152  may employ a stereoscopic display scheme such as stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like. Stereoscopic schemes commonly used for home television receivers, or the like, include Wheatstone stereoscopic scheme, or the like. 
     The auto-stereoscopic scheme includes, for example, a parallax barrier scheme, a lenticular scheme, an integral imaging scheme, a switchable scheme, or the like. The projection scheme includes a reflective holographic scheme, a transmissive holographic scheme, or the like. 
     In general, a 3D stereoscopic image is comprised of a left image (a left eye image) and a right image (a right eye image). According to how left and right images are combined into a 3D stereoscopic image, the 3D stereoscopic imaging method is divided into a top-down method in which left and right images are disposed up and down in a frame, an L-to-R (left-to-right, side by side) method in which left and right images are disposed left and right in a frame, a checker board method in which fragments of left and right images are disposed in a tile form, an interlaced method in which left and right images are alternately disposed by columns and rows, and a time sequential (or frame by frame) method in which left and right images are alternately displayed by time. 
     Also, as for a 3D thumbnail image, a left image thumbnail and a right image thumbnail are generated from a left image and a right image of the original image frame, respectively, and then combined to generate a single 3D thumbnail image. In general, thumbnail refers to a reduced image or a reduced still image. The thusly generated left image thumbnail and the right image thumbnail are displayed with a horizontal distance difference therebetween by a depth corresponding to the disparity between the left image and the right image on the screen, providing a stereoscopic space sense. 
     As illustrated, a left image and a right image required for implementing a 3D stereoscopic image is displayed on the stereoscopic display unit  152  by a stereoscopic processing unit (not shown). The stereoscopic processing unit may receive the 3D image and extract the left image and the right image, or may receive the 2D image and change it into a left image and a right image. 
     Here, if the display unit  151  and a touch sensitive sensor (referred to as a touch sensor) have a layered structure therebetween (referred to as a ‘touch screen’), the display unit  151  may be used as an input device as well as an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touchpad, and the like. 
     The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit  151 , or a capacitance occurring from a specific part of the display unit  151 , into electric input signals. Also, the touch sensor may be configured to sense not only a touched position and a touched area, but also touch pressure. Here, a touch object is an object to apply a touch input onto the touch sensor. Examples of the touch object may include a finger, a touch pen, a stylus pen, a pointer or the like. 
     When touch inputs are sensed by the touch sensors, corresponding signals are transmitted to a touch controller. The touch controller processes the received signals, and then transmits corresponding data to the controller  180 . Accordingly, the controller  180  may sense which region of the display unit  151  has been touched. 
     Still referring to  FIG. 1 , a proximity sensor  141  may be arranged at an inner region of the mobile terminal  100  covered by the touch screen, or near the touch screen. The proximity sensor  141  may be provided as one example of the sensing unit  140 . The proximity sensor  141  indicates a sensor to sense presence or absence of an object approaching to a surface to be sensed, or an object disposed near a surface to be sensed, by using an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor  141  has a longer lifespan and a more enhanced utility than a contact sensor. 
     The proximity sensor  141  may include a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and so on. When the touch screen is implemented as a capacitance type, proximity of a pointer to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor. 
     Hereinafter, for the sake of brief explanation, a status that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as ‘proximity touch’, whereas a status that the pointer substantially comes in contact with the touch screen will be referred to as ‘contact touch’. For the position corresponding to the proximity touch of the pointer on the touch screen, such position corresponds to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer. 
     The proximity sensor  141  senses proximity touch, and proximity touch patterns (e.g., distance, direction, speed, time, position, moving status, etc.). Information relating to the sensed proximity touch and the sensed proximity touch patterns may be output onto the touch screen. 
     When a touch sensor is overlaid on the stereoscopic display unit  152  in a layered manner (hereinafter, referred to as ‘stereoscopic touch screen’), or when the stereoscopic display unit  152  and a 3D sensor sensing a touch operation are combined, the stereoscopic display unit  152  may also be used as a 3D input device. 
     As examples of the 3D sensor, the sensing unit  140  may include a proximity sensor  141 , a stereoscopic touch sensing unit  142 , an ultrasonic sensing unit  143 , and a camera sensing unit  144 . 
     The proximity sensor  141  detects the distance between a sensing object (e.g., the user&#39;s finger or a stylus pen) applying a touch by using the force of electromagnetism or infrared rays without a mechanical contact and a detect surface. By using the distance, the terminal recognizes which portion of a stereoscopic image has been touched. In particular, when the touch screen is an electrostatic touch screen, the degree of proximity of the sensing object is detected based on a change of an electric field according to proximity of the sensing object, and a touch to the 3D image is recognized by using the degree of proximity. 
     The stereoscopic touch sensing unit  142  is configured to detect the strength or duration of a touch applied to the touch screen. For example, the stereoscopic touch sensing unit  142  may sense touch pressure. When the pressure is strong, it may recognize the touch as a touch with respect to an object located farther away from the touch screen toward the inside of the terminal. 
     The ultrasonic sensing unit  143  is configured to recognize position information of the sensing object by using ultrasonic waves. 
     The ultrasonic sensing unit  143  may include, for example, an optical sensor and a plurality of ultrasonic sensors. The optical sensor is configured to sense light and the ultrasonic sensors may be configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, a time for which the light reaches the optical sensor is much shorter than a time for which the ultrasonic wave reaches the ultrasonic sensor. Therefore, a position of a wave generation source may be calculated by using a time difference from the time that the ultrasonic wave reaches based on the light as a reference signal. 
     The camera sensing unit  144  includes at least one of a camera  121 , a photo sensor, and a laser sensor. 
     For example, the camera  121  and the laser sensor may be combined to detect a touch of the sensing object with respect to a 3D stereoscopic image. When distance information detected by a laser sensor is added to a 2D image captured by the camera, 3D information can be obtained. 
     In another example, a photo sensor may be laminated on the display device. The photo sensor is configured to scan a movement of the sensing object in proximity to the touch screen. In detail, the photo sensor includes photo diodes and transistors at rows and columns to scan content mounted on the photo sensor by using an electrical signal changing according to the quantity of applied light. Namely, the photo sensor calculates the coordinates of the sensing object according to variation of light to thus obtain position information of the sensing object. 
     The audio output module  153  may convert and output as sound audio data received from the wireless communication unit  110  or stored in the memory  160  in a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. Also, the audio output module  153  may provide audible outputs related to a particular function performed by the mobile terminal  100  (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module  153  may include a speaker, a buzzer or the like. 
     The alarm unit  154  outputs a signal for informing about an occurrence of an event of the mobile terminal  100 . Events generated in the mobile terminal may include call signal reception, message reception, key signal inputs, a touch input etc. In addition to video or audio signals, the alarm unit  154  may output signals in a different manner, for example, using vibration to inform about an occurrence of an event. The video or audio signals may be also outputted via the audio output module  153 , so the display unit  151  and the audio output module  153  may be classified as parts of the alarm unit  154 . 
     A haptic module  155  generates various tactile effects the user may feel. A typical example of the tactile effects generated by the haptic module  155  is vibration. The strength and pattern of the haptic module  155  can be controlled. For example, different vibrations may be combined to be outputted or sequentially outputted. 
     Besides vibration, the haptic module  155  may generate various other tactile effects such as an effect by stimulation such as a pin arrangement vertically moving with respect to a contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a contact on the skin, a contact of an electrode, electrostatic force, etc., an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat. 
     The haptic module  155  may be implemented to allow the user to feel a tactile effect through a muscle sensation such as fingers or arm of the user, as well as transferring the tactile effect through a direct contact. Two or more haptic modules  155  may be provided according to the configuration of the mobile terminal  100 . 
     The memory  160  may store software programs used for the processing and controlling operations performed by the controller  180 , or may temporarily store data (e.g., a phonebook, messages, still images, video, etc.) that are inputted or outputted. In addition, the memory  160  may store data regarding various patterns of vibrations and audio signals outputted when a touch is inputted to the touch screen. 
     The memory  160  may include at least one type of storage medium including a Flash memory, a hard disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. Also, the mobile terminal  100  may be operated in relation to a web storage device that performs the storage function of the memory  160  over the Internet. 
     The interface unit  170  serves as an interface with every external device connected with the mobile terminal  100 . For example, the external devices may transmit data to an external device, receives and transmits power to each element of the mobile terminal  100 , or transmits internal data of the mobile terminal  100  to an external device. For example, the interface unit  170  may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like. 
     The identification module may be a chip that stores various information for authenticating the authority of using the mobile terminal  100  and may include a user identity module (UIM), a subscriber identity module (SIM) a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (referred to as ‘identifying device’, hereinafter) may take the form of a smart card. Accordingly, the identifying device may be connected with the terminal  100  via the interface unit  170 . 
     When the mobile terminal  100  is connected with an external cradle, the interface unit  170  may serve as a passage to allow power from the cradle to be supplied therethrough to the mobile terminal  100  or may serve as a passage to allow various command signals inputted by the user from the cradle to be transferred to the mobile terminal therethrough. Various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle. 
     The controller  180  typically controls the general operations of the mobile terminal. For example, the controller  180  performs controlling and processing associated with voice calls, data communications, video calls, and the like. The controller  180  may include a multimedia module  181  for reproducing multimedia data. The multimedia module  181  may be configured within the controller  180  or may be configured to be separated from the controller  180 . 
     The controller  180  may perform a pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. 
     Also, the controller  180  may execute a lock state to restrict a user from inputting control commands for applications when a state of the mobile terminal meets a preset condition. Also, the controller  180  may control a lock screen displayed in the lock state based on a touch input sensed on the display unit  151  in the lock state of the mobile terminal. 
     The power supply unit  190  receives external power or internal power and supplies appropriate power required for operating respective elements and components under the control of the controller  180 .

     Hereinafter, a communication system which is operable with the mobile terminal  100  according to the present disclosure will be described. 
       FIGS. 2A and 2B  are conceptual views of a communication system operable with a mobile terminal  100  in accordance with the present disclosure. 
     First, referring to  FIG. 2A , such communication systems utilize different air interfaces and/or physical layers. Examples of such air interfaces utilized by the communication systems include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS), the Long Term Evolution (LTE) of the UMTS, the Global System for Mobile Communications (GSM), and the like. 
     By way of non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types including the CDMA wireless communication system. 
     Referring now to  FIG. 2A , a CDMA wireless communication system is shown having a plurality of mobile terminals  100 , a plurality of base stations (BSs)  270 , base station controllers (BSCs)  275 , and a mobile switching center (MSC)  280 . The MSC  280  is configured to interface with a conventional Public Switch Telephone Network (PSTN)  290 . The MSC  280  is also configured to interface with the BSCs  275 . The BSCs  275  are coupled to the base stations  270  via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, the plurality of BSCs  275  can be included in the system as shown in  FIG. 2A . 
     Each base station  270  may include one or more sectors, each sector having an omni-directional antenna or an antenna pointed in a particular direction radially away from the base station  270 . Alternatively, each sector may include two or more different antennas. Each base station  270  may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz, etc.). 
     The intersection of sector and frequency assignment may be referred to as a CDMA channel. The base stations  270  may also be referred to as Base Station Transceiver Subsystems (BTSs). In some cases, the term “base station” may be used to refer collectively to a BSC  275 , and one or more base stations  270 . The base stations may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station  270  may be referred to as cell sites. 
     A broadcasting transmitter (BT)  295 , as shown in  FIG. 2A , transmits a broadcast signal to the mobile terminals  100  operating within the system. The broadcast receiving module  111  ( FIG. 1 ) is typically configured inside the mobile terminal  100  to receive broadcast signals transmitted by the BT  295 . 
       FIG. 2A  further depicts several Global Positioning System (GPS) satellites  300 . Such satellites  300  facilitate locating the position of at least one of plural mobile terminals  100 . Two satellites are depicted in  FIG. 2A , but it is understood that useful position information may be obtained with greater or fewer satellites than two satellites. The GPS module  115  ( FIG. 1 ) is typically configured to cooperate with the satellites  300  to obtain desired position information. It is to be appreciated that other types of position detection technology, (i.e., location technology that may be used in addition to or instead of GPS location technology) may alternatively be implemented. If desired, at least one of the GPS satellites  300  may alternatively or additionally be configured to provide satellite DMB transmissions. 
     During typical operation of the wireless communication system, the base stations  270  receive sets of reverse-link signals from various mobile terminals  100 . The mobile terminals  100  are engaging in calls, messaging, and executing other communications. Each reverse-link signal received by a given base station  270  is processed within that base station  270 . The resulting data is forwarded to an associated BSC  275 . The BSC  275  provides call resource allocation and mobility management functionality including the orchestration of soft handoffs between base stations  270 . The BSCs  275  also route the received data to the MSC  280 , which then provides additional routing services for interfacing with the PSTN  290 . Similarly, the PSTN  290  interfaces with the MSC  280 , and the MSC  280  interfaces with the BSCs  275 , which in turn control the base stations  270  to transmit sets of forward-link signals to the mobile terminals  100 . 
     Hereinafter, description will be given of a method for acquiring location information of a mobile terminal using a wireless fidelity (WiFi) positioning system (WPS), with reference to  FIG. 2B . 
     The WiFi positioning system (WPS)  300  refers to a location determination technology based on a wireless local area network (WLAN) using WiFi as a technology for tracking the location of the mobile terminal  100  using a WiFi module provided in the mobile terminal  100  and a wireless access point  320  for transmitting and receiving to and from the WiFi module. 
     The WiFi positioning system  300  may include a WiFi location determination server  310 , a mobile terminal  100 , a wireless access point (AP)  320  connected to the mobile terminal  100 , and a database  330  stored with any wireless AP information. 
     The WiFi location determination server  310  extracts the information of the wireless AP  320  connected to the mobile terminal  100  based on a location information request message (or signal) of the mobile terminal  100 . The information of the wireless AP  320  may be transmitted to the WiFi location determination server  310  through the mobile terminal  100  or transmitted to the WiFi location determination server  310  from the wireless AP  320 . 
     The information of the wireless AP extracted based on the location information request message of the mobile terminal  100  may be at least one of MAC address, SSID, RSSI, channel information, privacy, network type, signal strength and noise strength. 
     The WiFi location determination server  310  receives the information of the wireless AP  320  connected to the mobile terminal  100  as described above, and compares the received wireless AP  320  information with information contained in the pre-established database  330  to extract (or analyze) the location information of the mobile terminal  100 . 
     On the other hand, referring to  FIG. 2B , as an example, the wireless AP connected to the mobile terminal  100  is illustrated as a first, a second, and a third wireless AP  320 . However, the number of wireless APs connected to the mobile terminal  100  may be changed in various ways according to a wireless communication environment in which the mobile terminal  100  is located. When the mobile terminal  100  is connected to at least one of wireless APs, the WiFi positioning system  300  can track the location of the mobile terminal  100 . 
     Next, considering the database  330  stored with any wireless AP information in more detail, various information of any wireless APs disposed at different locations may be stored in the database  330 . 
     The information of any wireless APs stored in the database  330  may be information such as MAC address, SSID, RSSI, channel information, privacy, network type, latitude and longitude coordinate, building at which the wireless AP located, floor number, detailed indoor location information (GPS coordinate available), AP owner&#39;s address, phone number, and the like. 
     In this manner, any wireless AP information and location information corresponding to the any wireless AP are stored together in the database  330 , and thus the WiFi location determination server  310  may retrieve wireless AP information corresponding to the information of the wireless AP  320  connected to the mobile terminal  100  from the database  330  to extract the location information matched to the searched wireless AP, thereby extracting the location information of the mobile terminal  100 . 
       FIG. 3A  is a front perspective view of the mobile terminal  100  according to an embodiment of the present invention. 
     The mobile terminal  100  according to the present disclosure is a bar type mobile terminal. However, the present disclosure is not limited to this, but may be applied to a watch type, a clip type, a glasses type, or a slide type in which two or more bodies are coupled to each other so as to perform a relative motion, a folder type, or a swing type, a swivel type and the like. 
     A case (casing, housing, cover, etc.) forming an outer appearance of the body may include a front case  101  and a rear case  102 . A space formed by the front case  101  and the rear case  102  may accommodate various components therein. At least one intermediate case may further be disposed between the front case  101  and the rear case  102 . A battery cover  103  for covering a battery  191  may be detachably mounted to the rear case  102 . 
     Such cases may be formed by injection-molded synthetic resin, or may be formed using a metallic material such as stainless steel (STS) or titanium (Ti). 
     At the front case  101 , may be disposed a display unit  151 , a first audio output unit  153   a , a first camera  121   a , a first user input unit  131 , etc. On the side surfaces, may be disposed a microphone  122 , an interface unit  170 , a second user input unit  132 , etc. 
     The display unit  151  may output information processed in the mobile terminal  100 . The display unit  151  may be implemented using, for example, at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-Liquid Crystal Display (TFT-LCD), an Organic Light-Emitting Diode (OLED), a flexible display, a three-dimensional (3D) display, an e-ink display or the like. 
     The display unit  151  may include a touch sensing means to receive a control command by a touch method. When a touch is made to any one place on the display unit  151 , the touch sensing means may be configured to sense this touch and enter the content corresponding to the touched place. The content entered by a touch method may be a text or numerical value, or a menu item capable of indication or designation in various modes. 
     The touch sensing means may be formed with transparency to allow visual information displayed on the display unit  151  to be seen, and may include a structure for enhancing the visibility of a touch screen at bright places. Referring to  FIG. 3A , the display unit  151  occupies a most portion of the front surface of the front case  101 . 
     The first audio output unit  153   a  and the first camera  121   a  are disposed in a region adjacent to one of both ends of the display unit  151 , and the first manipulation input unit  131  and the microphone  122  are disposed in a region adjacent to the other end thereof. The second manipulation interface  132  (refer to  FIG. 3B ), the interface  170 , and the like may be disposed on a lateral surface of the terminal body. 
     The first audio output module  153   a  may be implemented in the form of a receiver for transferring voice sounds to the user&#39;s ear or a loud speaker for outputting various alarm sounds or multimedia reproduction sounds. 
     It may be configured such that the sounds generated from the first audio output module  153   a  are released along an assembly gap between the structural bodies. In this case, a hole independently formed to output audio sounds may not be seen or hidden in terms of appearance, thereby further simplifying the appearance of the mobile terminal  100 . However, the present invention may not be limited to this, but a hole for releasing the sounds may be formed on the window. 
     The first camera  121   a  processes video frames such as still or moving images obtained by the image sensor in a video call mode or capture mode. The processed video frames may be displayed on the display unit  151 . 
     The user input unit  130  is manipulated to receive a command for controlling the operation of the mobile terminal  100 . The user input unit  130  may include a first and a second manipulation unit  131 ,  132 . The first and the second manipulation unit  131 ,  132  may be commonly referred to as a manipulating portion, and any method may be employed if it is a tactile manner allowing the user to perform manipulation with a tactile feeling such as touch, push, scroll or the like. 
     In the present drawing, it is illustrated on the basis that the first manipulation unit  131  is a touch key, but the present disclosure may not be necessarily limited to this. For example, the first manipulation unit  131  may be configured with a mechanical key, or a combination of a touch key and a mechanical key. 
     The content received by the first and/or second manipulation units  131 ,  132  may be set in various ways. For example, the first manipulation unit  131  may be used to receive a command such as menu, home key, cancel, search, or the like, and the second manipulation unit  132  may receive a command, such as controlling a volume level being outputted from the first audio output module  153   a , or switching into a touch recognition mode of the display unit  151 . 
     The microphone  122  may be formed to receive the user&#39;s voice, other sounds, or the like. The microphone  122  may be provided at a plurality of places, and configured to receive stereo sounds. 
     The interface unit  170  serves as a path allowing the mobile terminal  100  to exchange data with external devices. For example, the interface unit  170  may be at least one of a connection terminal for connecting to an earphone in a wired or wireless manner, a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), and a power supply terminal for supplying power to the mobile terminal  100 . The interface unit  170  may be implemented in the form of a socket for accommodating an external card such as Subscriber Identification Module (SIM) or User Identity Module (UIM), and a memory card for information storage. 
       FIG. 3B  is a rear perspective view illustrating mobile terminal  100  illustrated in  FIG. 3A . 
     Referring to  FIG. 3B , a second camera  121   b  may be additionally mounted at a rear surface of the terminal body, namely, the rear case  102 . The second camera  121   b  has an image capturing direction, which is substantially opposite to the direction of the first camera unit  121   a  (refer to  FIG. 3A ), and may have a different number of pixels from that of the first camera unit  121   a.    
     For example, it is preferable that the first camera  121   a  has a relatively small number of pixels enough not to cause difficulty when the user captures his or her own face and sends it to the other party during a video call or the like, and the second camera  121   b  has a relatively large number of pixels since the user often captures a general object that is not sent immediately. The first and the second camera  121   a ,  121   b  may be provided in the terminal body in a rotatable and popupable manner. 
     Furthermore, a flash  123  and a mirror  124  may be additionally disposed adjacent to the second camera  121   b . The flash  123  illuminates light toward an object when capturing the object with the second camera  121   b . The mirror  124  allows the user to look at his or her own face, or the like, in a reflected way when capturing himself or herself (in a self-portrait mode) by using the second camera  121   b.    
     A second audio output unit  153   b  may be additionally disposed at a rear surface of the terminal body. The second audio output unit  153   b  together with the first audio output unit  153   a  (refer to  FIG. 3A ) can implement a stereo function, and may be also used to implement a speaker phone mode during a phone call. 
     An antenna (not shown) for receiving broadcast signals may be additionally disposed at a lateral surface of the terminal body in addition to an antenna for making a phone call or the like. The antenna constituting part of the broadcast receiving module  111  (refer to  FIG. 1 ) may be provided in the terminal body in a retractable manner. 
     A power supply unit  190  (refer to  FIG. 1 ) for supplying power to the mobile terminal  100  may be mounted on the terminal body. The power supply unit  190  may be incorporated into the terminal body, or may include a battery  191  configured in a detachable manner on the outside of the terminal body. According to the drawing, it is illustrated that the battery cover  103  is combined with the rear case  102  to cover the battery  191 , thereby restricting the battery  191  from being released and protecting the battery  191  from external shocks and foreign substances. 
     A display unit that is in an inactivated state according to an embodiment of the present invention displays predetermined screen information when a main body of a mobile terminal is moved. The phrase “state in which a display  151  is inactivated” used therein means that an internal light for illuminating the display unit  151  is turned off. That is, when the display unit  151  is inactivated, no information or graphic image is displayed on the display unit  151 . 
     In other words, when the display unit  151  is inactivated, the control unit  180  may control the sensing unit  120  to sense a movement of the main body of the terminal and display screen information on the display unit  151  or switch the display unit  151  to be activated when the movement is sensed. 
       FIG. 4  is a flowchart showing a method of controlling a mobile terminal according to an embodiment of the present invention, and  FIG. 5A  is a conceptual view showing the control method shown in  FIG. 4  according an embodiment of the present invention. 
     In operation S 601 , a plurality of images that are separated from one another are displayed together on the display unit  151 . For example, screen information  600  displayed on the display unit  151  may correspond to an execution screen of a gallery application for displaying at least one image  510  that is photographed or stored using another path. 
     The display unit  151  may display a predetermined number of images  510  together. That is, the plurality of images  510  that are displayed together on the display unit  151  may be downsized and displayed in substantially the same size. The plurality of images  510  may be sequentially arranged according to a storage order, storage method, or capacity of the memory  160 . In the drawing, nine images are shown to be displayed together. However, the present invention is not limited thereto. 
     That is, a larger or smaller number of images may be displayed together by a user&#39;s setting. For example, on the basis of a pinch-in or pinch-out type touch input while the screen information  500  is displayed, the control unit controls the display unit  151  to display a larger or smaller number of images. 
     Although not shown in the drawing, a user may apply a touch input to one of the plurality of images  510  to select the image. For example, the control unit may control the display unit  151  to display the image, to which the touch input is applied, on the entire display unit  151 . 
     In addition, the control unit may control a function (for example, copy, deletion, editing, or movement) corresponding to the image by any other type of touch input (for example, a long touch input). 
     The plurality of images  510  are displayed separately from one another. That is, the plurality of images  510  are displayed to have separation spaces  510 ′ which are spaced at a predetermined distance. The separation spaces  510 ′ may be defined along edges of the images  510  and displayed in a predetermined color such as black. 
     According to an embodiment of the present invention, a touch input is applied to the separation space (hereinafter referred to as a control region) for separating the plurality of images in operation S 602 . Referring to (a) of  FIG. 5A , the screen information  500  includes an editing menu  501  for editing the image. For example, a touch input for adjusting a brightness of the image, changing a display form of the image, enlarging or reducing the image, or changing a display direction of the image may be applied to the editing menu  501 . The editing menu  501  includes a plurality of icons for receiving respective touch inputs for respective editing items. That is, when the plurality of images are displayed, the control unit  180  may control the display unit  151  to display the editing menu  501 . 
     Alternatively, while the plurality of images are displayed, the control unit  180  may control the display unit  151  to display the editing menu  501  when a predetermined touch input is applied, or when any touch input is applied to the control region. 
     When a touch input is applied to the editing menu  501 , the control unit  180  may control the display unit  151  to display a first control image  610  in the control region  510 ′. The first control image  610  may be displayed in the form of a line segment that extends along the control region  510 ′. However, the form is not limited thereto. 
     For example, when a brightness icon is selected from the editing menu  501  to adjust brightness, the form of the brightness icon is transformed and then displayed. Further, the control unit  180  controls the display unit  151  to display the first control image  610  for receiving a user&#39;s touch input in order to adjust the brightness. 
     However, the present invention is not limited to the above-described order. For example, a touch input may be applied to the brightness icon in order to adjust a display brightness of the image  510  while the first control image  610  is displayed. In this case, when a touch input is applied to an effect icon while the first control image  610  is displayed, a touch input for changing a display effect of the image may be applied to the first control image  610 . 
     Referring to (b) of  FIG. 5A , the first control image  610  includes a plurality of line segments extending in a horizontal direction between the images  510 . When nine images are displayed on the display unit  151 , the first control image  610  may include three line segments that are parallel to one another. 
     Alternatively, according to another embodiment of the present invention, the first control image  610  may not be displayed. For example, a touch input applied to the control space  510 ′ between the images may be sensed. That is, with the first control image  610 , a user may recognize a region where a touch input is to be applied. 
     In operation S 603 , the control unit  180  controls the display unit  151  to transform and display an image adjacent to the control region where the touch input is applied. Referring to (b) and (c) of  FIG. 5A , the control unit  180  may control the display unit  151  to transform and display a brightness of one of the plurality of images on the basis of the touch input applied to the first control image  610  while the brightness icon is selected. 
     The image to be transformed and displayed is determined as at least one image adjacent to one region of the first control image  610 , in which the touch input is applied. Referring to (b) and (c) of  FIG. 5A , on the basis of a touch input that is applied to a central region of the first control image  610  in the second row on the display unit  151 , a image ( 510 ; an image corresponding to the second row and second column) adjacent to the central region is darkly displayed. 
     In order to change the form of the image  510 , the touch input applied to the first control image  610  may correspond to a continuous touch input. For example, the touch input type may correspond to a dragging type in which a touch input is first applied to the first control image  610  and continuously moved. 
     Although not shown in the drawing, the control unit  180  may control the display unit  151  to transform and display the first control image  610  when a touch input is applied to the first control image  610  or the control region  510 ′ other than the image  510 . Thus, a user may sense that the touch input has been applied to the first control image  610 . Alternatively, when the touch input is applied to the control region  510 ′ while the first control image  610  is not displayed, the display unit  151  may display the first control image  610  extending from a region where the touch input has been applied. 
     In order to transform the image  510 , the dragging type touch input may be applied in a direction intersecting with an extending direction of the first control image  610 . That is, the user may control a display brightness to make the image  510  brighter or darker by applying a touch input in both directions perpendicular to the extending direction. 
     Fore example, as shown in the drawing, a continuous touch input may be applied downward (with respect to the drawing) from a region of the first control image  610  adjacent to the image  510 . In this case, the control unit  180  may control the display unit  151  to decrease a display brightness of the image  510  to make the image  510  darker. 
     Although not shown in the drawing, the control unit  180  may control the display unit  151  to increase the display brightness of the image  510  to make the image brighter when a continuous touch input is applied upward (with respect to the drawing) from a region of the first control image  610  adjacent to the image  510 . 
     That is, a user may select a region of the first control image  610  to select an image to be transformed and displayed. Alternatively, the user may select a transforming method by applying continuous touch inputs having different directions to the first control image  610 . 
     The display unit  151  may transform and display the first control image  610  on the basis of the continuous touch input applied to the first control image  610 . That is, the display unit  151  may display one region of the first control image  610  in the form in which the region is stretched according to the continuously moved touch input. That is, the control unit  180  transforms and displays the first control image  610  in the form of a rubber band that is stretched in a direction where the touch input is moved. 
     Further, the display unit  151  may display the first control image  610  that is before the transformation as if the rubber band is restored by the elastic force when the touch input applied to the control image  610  is released. That is, the user may feel like the first control image is flicked by applying a touch input to some of the first control image  610  and may feel like the image selected is transformed by flicking the first control image  610 . 
     Although not shown in detail in the drawing, when a touch input applied to the first control image  610  is released, the display unit  151  may display the first control image  610  that is vibrated while being moved back to its original position. 
     According to an embodiment of the present invention, a touch sensing unit of the display unit  151  receives a touch input applied to a control region between images while a plurality of images are displayed together. It is possible to select an image adjacent to the control region where the touch input is received and transform the selected image on the basis of a touch input scheme. 
     That is, it is possible to easily select one of the plurality images and to simply transform and display the selected image in a desired method without switching the screen. 
     In addition, a control image may be displayed between the plurality of images, thus allowing a user to easily recognize a touch region. The control image may be transformed in an elastic form according to a touch input of a user, thus providing the user with a feeling like flicking an elastic material. 
     As described above, the image may be transformed in various methods on the basis of selection of one icon from the editing menu  501 . Various modifications of the image will be described below. 
       FIGS. 5B to 5C  show a control method for transforming an image in various methods using a control image. Other than the form in which the image is transformed, a touch input applied to the first control image and a control method for the same, and a control method for displaying the first control image are substantially the same as described in  FIG. 5A . Therefore, a repeated description thereof will be described. 
     Referring to  FIG. 5B , the control unit  180  may control the display unit  151  to display a first control image  610  on the basis of selection of an effect icon from the editing menu  501 . The form of the first control image  610  may be substantially the same as or different from that of when another icon is selected from the editing menu  501 . 
     The control unit  180  selects one of the plurality of images on the basis of one region of the first control image  610 , in which a touch input is applied. The control unit  180  may control the display unit  151  to apply a predetermined effect to the selected image on the basis of the continuous touch input that are applied to the first control image  610  and then to display the image to which the predetermined effect is applied. 
     Here, the term “effect” means a variety of transforming method for displaying an image. That is, different display methods are determined to provide a user with different feelings by adjusting brightness, chroma, and sharpness and applying various filters. 
     The control unit  180  may define a predetermined number of effects. In addition, the control unit  180  controls the display unit  151  to apply one of effects, which are sequentially listed, on the basis of a one-directional touch input applied to the first control image  610  and to display the image  510 . 
     Further, the control unit  180  controls the display unit  151  to apply a next effect and to display the image  510  when a one-directional touch input is applied to the first control image  610  again. Although not shown in the drawing, the display unit  151  may apply the effects that are sequentially listed to the image on the basis of the touch input that is repeatedly applied and display the image. 
     In addition, the control unit  180  may control the display unit  151  to apply a previous effect and to display the image  510  when an opposite directional touch input is applied to the first control image  610 . 
     A control method for enlarging or reducing an image on the basis of a touch input applied to the first control image will be described with reference to  FIG. 5C . The control unit  180  may control the display unit  151  to enlarge and display the image  510  on the basis of an one-directional continuous touch input applied to the first control image  610 . 
     However, a size on the display unit  151  on which the image  510  is displayed is constant. That is, the display unit  151  displays an enlarged region of the image  510  on the basis of the touch input. 
     The display unit  151  may reduce and display the image on the basis of an opposite directional touch input applied to the first control image  610 . In this case, a region of the display unit  151  on which the image  510  is displayed is also constant. That is, the control unit  180  may control the display unit  151  to entirely reduce the image  510  and to display the reduced image  510  to an existing display region. 
     Thus, a user may be provided with one image having an enlarged or reduced region while a plurality of images are displayed together. 
       FIGS. 6A to 6C  are conceptual views showing various control images. 
     A second image that is displayed to indicate a degree of control of an image will be described with reference to  FIG. 6A . When one icon is selected from the editing menu  501 , the display unit  151  displays the first control image  610  having a form of a line segment extending in one direction. As shown in the drawings, the first control image  610  is in a line segment extending in a horizontal direction, and may be displayed in a control region  510 ′ adjacent to respective bottom edges of the plurality of images. 
     The control unit  180  controls the display unit  151  to display a status indication point  620  in a control region adjacent to respective side edges of the plurality of images along with the first control image  610 . The status indication point  620  may have the form of a dot. However, the form is not limited thereto. 
     The statue indication point  620  is displayed at a position for indicating a degree of control corresponding to a function of an icon selected from the editing menu, with respect to a side length of each image. For example, when the brightness icon is selected, if one region of the first control image  610  is touched, the status indication point  620  is displayed on the basis of a degree of brightness of the image selected by the control image  610 . For example, the status indication point  620  may be displayed to a right side of the selected image. The status indication point is displayed close to a top of the image  510  when the image  510  is bright and is displayed close to a bottom of the image  510  when the image  510  is dark. 
     However, the present invention is not limited thereto. For example, when a touch input is applied to the brightness icon, a plurality of status indication points  620  may be displayed to indicate brightness for all images that are displayed on the display unit  151 . 
     In addition, when brightness of the image  510  is adjusted on the basis of the touch input applied to the first control image  610 , a position of the statue display point  620  is moved corresponding to the adjusted brightness. 
     Thus, a user may recognize a degree of transformation of a display status of the image on the basis of the status indication point  620  having a position transformed on the basis of the touch input applied to the first control image  610 . 
     The third control image  630  having a form different from the first control image will be described with reference to  FIG. 6B . Except the form of the third control image  630 , a control method using the third control image  630  is substantially the same as the control method using the first control image  610 . Thus, a repeated description thereof will be omitted. 
     The third control image  630  may have the form of a scroll bar and be provided in a plural number corresponding to respective images. As shown in the drawings, the third control image  630  may extend in a horizontal direction with respect to the images  510  and may be formed to correspond to a width of respective images  510 . 
     The third control image  630  includes a scroll box for indicating statuses of respective images corresponding to control items selected from the editing menu  501 . For example, the scroll box is displayed on a position for indicating brightness of respective images with respect to the length of the scroll bar. 
     The control unit  180  may transform the image on the basis of a user&#39;s touch input that applied to the scroll box. That is, the touch input applied to the third control image  630  may correspond to a continuous touch that reciprocates along an extending direction in which the scroll bar is formed. 
     The control unit  180  selects an image  150  corresponding to the third control image  630  where a user&#39;s touch is applied. The control unit  180  may control the display unit  151  to transform and display the image on the basis of a touch input that is continuously applied to the third control image  630 . In addition, the display unit  151  moves and displays the scroll box on the basis of the continuous touch input. 
     Thus, a user may recognize a display status of each image on the basis of a position of the scroll box and facilitate control of a display of an image by applying the touch input to a scroll bar-formed third image. 
     A method of controlling a degree of transformation of an image on the basis of a degree of touch input applied to the first control image will be described with reference to  FIG. 6C . 
     The control unit  180  transforms and displays the image  510  when one icon is selected from the editing menu  501  and a continuous touch input is applied to the first control image. 
     The control unit  180  may control the display unit  151  to transform and display the image  510  on the basis of a degree of transformation corresponding to a movement range of the touch input that is continuously applied to the first control image  610 . That is, the degree of transformation is defined to increase as the movement range increases. 
     For example, when brightness of an image is selected to be adjusted, the degree of transformation is defined to increase as the movement range of the continuous touch input applied to the first control image  610  increases. Thus, as a distance from a region of the first control image  610  to which the touch input is first applied to a region to which the touch input is released increases, the brightness changes significantly. 
     Thus, a user may significantly transform and display the image on the basis of a one-time touch input applied to the first control image. 
     In addition, the display unit  151  transforms and displays the first control image to form a portion of the first control image  610  in a touch region that is in contact with the display unit  151  on the basis of a touch input that is moved on the display unit  151 . That is, the first control image  610  is stretched by the touch input. 
     Thus, the user may predict a degree of transformation of an image on the basis of a degree of transformation of the first control image  610 . 
     Although not shown in the drawing, when the transformation of an effect in which the image is displayed in a predetermined number is selected, the control unit  180  may select one of sequential effects in proportion to a movement range of a touch input applied to the first control image  610 . 
       FIGS. 7A to 7D  are conceptual views showing a control method for transforming an image on the basis of touch inputs that are applied to a control region according to various embodiments of the present invention. 
     A control method for transforming and displaying a plurality of images substantially simultaneously will be described with reference to  FIG. 7A . According to an embodiment of the present invention, a plurality of touch inputs may be applied to different regions of the first control image  610 . 
     When the plurality of touch inputs are applied to specific regions of the first control image  610 , the control unit  180  selects first and second images  510  and  512  corresponding to respective touch inputs. In the drawings, the first and second images  510  and  512  are shown to be disposed adjacent to each other. However, the present invention is not limited thereto. 
     When a plurality of touch input is applied to the first control image  610  and one image is selected by the plurality of touch input, the control unit  180  senses the plurality of touch inputs as one touch input. 
     When the first and second images  510  and  512  are selected on the basis of the plurality of touch inputs, the control unit  180  controls the first and second images  510  and  512  independently on the basis of the respective touch input. 
     That is, display of the respective image is controlled on the basis of the respective touch inputs, which do not affect each other. The control unit  180  may control the display unit  151  to transform and display the first and second images  510  and  512  on the basis of independent touch inputs applied to a plurality of regions of the first control image  610 . 
     That is, a user may transform and display a plurality of images substantially simultaneously by applying touch inputs to a plurality of regions of the first control image  610  at the same time. 
     A control method for displaying a plurality of control images corresponding to a selected plurality of editing items will be described with reference to  FIG. 7B . The control unit  180  may select a plurality of editing items together on the basis of touch inputs applied to a plurality of icons in the editing menu  501 . 
     The control unit  180  controls the display unit  151  to display a plurality of control images corresponding to the selected plurality of editing items. The plurality of control images are displayed in the control region  510 ′ that is formed between the images. 
     For example, a brightness item and a beauty item may be selected by a user&#39;s touch input. Here, the beauty item is used to apply an effect for making a person look more beautiful to an image and display the image on the basis of a predetermined criteria (for example, a face of the person is brighter, a region of the face is dimmer, eyes of the face is larger). 
     The first control image  610  corresponding to the brightness item is displayed in a control region  510 ′ adjacent to a bottom edge of the image  510 , and formed to extend in a horizontal direction. In addition, the fourth control image  640  corresponding to the beauty item is displayed in a control region  510 ′ adjacent to a left side edge of the image, and formed to extend in a vertical direction. The first control image  610  and the fourth control image  640  may have different forms from each other. For example, the first and fourth control images  610  and  640  may be displayed in different colors from each other. 
     On the basis of the touch inputs applied to the first and fourth control images  610  and  640 , the control unit  180  may control the display unit  151  to transform and display the selected image according to items corresponding to respective control images. 
     For example, while the first and fourth control images  610  and  640  are displayed, the control unit  180  transforms and displays the selected image on the basis of the touch inputs applied to the control images. Alternatively, the control unit  180  may select different images on the basis of one region of the touch input applied to the control image. 
     Although not shown in detail in the drawings, when a touch input is applied to an icon corresponding to the selected item again, the control unit  180  may control the display unit  151  to release the selection and limit the display of a corresponding control image. 
     Thus, the display unit  151  may display control images for different items and may transform and display the selected image according to the respective items by applying the touch input to the respective control images. 
     A control method for changing a rotational direction of an image on the basis of a touch input applied to a control image will be described with reference to  FIGS. 7C and 7D . 
     The editing menu  501  includes a rotation/reversal item for rotating a display direction of the image or reversing the image. When a touch input is applied to the rotation/reversal icon, the control unit  180  controls the display unit  151  to display a fifth control image  650  that extends in directions intersecting with each other and that are displayed in the control region  510 ′. The fifth control image  650  may be formed in the form of a plurality of line segments that extend in directions perpendicular to each other to surround the image. 
     Referring to  FIG. 7C , the control unit  180  selects an image  510  displayed between two regions on the basis of a touch input that is applied together to the two regions of the fifth control images  650  adjacent to left and right sides of the image  510 . 
     The control unit  180  may rotate a display direction of the image  510  at a 90 degree angle on the basis of a continuous touch input that is applied in opposite directions in the two regions and display the rotated image. Here, the opposite directions correspond to an extending direction of the fifth control image having the form of the line segment. That is, the touch inputs applied to the two regions are applied in the same rotational direction with respect to the image, and the display unit  151  rotates the image at a 90 degree angle in the rotational direction and display the rotated image. 
     Referring to  FIG. 7D , the control unit  180  selects the image  510  displayed between the two touch inputs on the basis of the respective touch inputs applied to two line segments that extend in a horizontal direction. The control unit  180  may control the display unit  151  to reverse and display the image on the basis of continuous touch inputs that are applied in opposite directions with respect to the selected image  510 . Here, the two opposite directions correspond to an extending direction of the fifth control image having the form of the line segment. 
     According to an embodiment of the present invention, it is possible to select one image on the basis of two touch inputs applied to two line segments that are displayed in parallel to each other and to change the display direction of the image on the basis of the touch inputs having opposite directions. 
       FIGS. 8A to 8C  are conceptual views showing a control method for transforming and display at least one image selected from among a plurality of images. 
     A control method when a selected image is displayed on an adjacent region will be described with reference to  FIG. 8A . When a continuous touch input moved along the sixth control image  660  forms a closed loop (that is, the touch input is released in the region to which the touch input has initially been applied) while the sixth control image  660  is displayed, the control unit  180  may select at least one image displayed inside the closed loop. That is, at least one image selected by the continuous touch input is disposed adjacent to each other. 
     When first to fourth images  510 ,  512 ,  513 , and  514  are selected by a continuous touch input applied along the sixth control image  660 , the control unit  180  controls the display unit  151  to highlight the first to fourth images  510 ,  512 ,  513 , and  514 . For example, the display unit  151  may increase a border thickness of the first to fourth images  510 ,  512 ,  513 , and  514 . 
     Referring to (b) and (c) of  FIG. 8A , the control unit  180  may select one editing item on the basis of a touch input applied to the editing menu  501 . For example, an icon for adjusting brightness may be selected on the basis of a touch input applied to one icon. 
     When a touch input is applied to one icon, the control unit  108  controls the display unit  151  to suppress a display of the sixth image  660  and to display a first transformed image  611 . 
     The first transformed image  611  may have the form of a line segment extending in one direction. The first transformed image  611  may be a portion of the sixth control image  660  that forms the closed loop. For example, the first transformed image  611  may be formed along the edges of the plurality of images to extend in one direction. That is, the first transformed image  611  may be displayed to have the form of a line segment extending in a horizontal direction along bottom edges of the first and second images  510  and  5112 . 
     The control unit  180  may control the display unit  151  to transform and display the first to fourth images  510 ,  512 ,  513 , and  514  on the basis of a touch input applied to the first transformed image  611 . Here, the touch input may correspond to a continuous touch input applied in a direction intersecting with an extending direction of the first transformed image  611 . 
     However, when the first transformed image  611  has the form of a scroll bar, the touch input may correspond to a continuous touch input moved along an extending direction of the first transformed image  611 . 
     The control unit  180  controls the display unit  151  to adjust brightnesses of the first to fourth images  510 ,  512 ,  513 , and  514  at one time on the basis of the touch input and to display the first to fourth images  510 ,  512 ,  513 , and  514  having the adjusted brightnesses. For example, when the brightnesses of the first to fourth images  510 ,  512 ,  513 , and  514  are the same as one another, brightnesses of the transformed first to fourth images  510 ,  512 ,  513 , and  514  are substantially the same. 
     When the brightnesses of the first to fourth images  510 ,  512 ,  513 , and  514  are different from one another, the control unit  180  may adjust the brightnesses on the basis of substantially the same degree of transformation according to a movement range of the touch input applied to the first transformed image  611 . That is, the transformed images may be displayed to have different brightnesses from one another. 
     That is, a user may select a plurality of images adjacent to one another based of the displayed control image and adjust display statuses of the images at one time. 
     A control method for adjusting display statuses of a selected plurality of images at one time will be described with reference to  FIG. 8B . Referring to (a) of  FIG. 8B , when one item is selected from the editing menu  501 , the control unit  180  may select some of a plurality of images having touch inputs applied thereto. When the touch input is applied, the control unit  180  selects an image having the touch input applied thereto and highlights the image to indicate that the image has been selected. For example, the display unit  151  increases a border thickness of the image selected on the basis of the touch input. 
     Thus, a user may select independent images that spaced apart from one another. In the drawings, the first to third images  510 ,  512 , and  513  are shown to be adjacent to each other. However, according to an embodiment of the present invention, a user may select a plurality of images that are displayed to be spaced apart such that the plurality of images may not share the side with one another on the basis of a touch input applied to the images. 
     The control unit  180  controls the display unit  151  to display a second transformed image  612  to be adjacent to one of the plurality of images. For example, the display unit  151  displays the second transformed image  612  to be adjacent to an image that is finally selected (that is, an image having a final touch input applied thereto). 
     The second transformed image  612  corresponds to a length of one side of one image. For example, the second transformed image  612  is formed along a bottom side of the first image  510 . 
     Referring to (b) and (c) of  FIG. 8B , the control unit  180  controls the display unit  151  to transform and display the first to third images  513 ,  512 , and  513  on the basis of a touch input applied to the second transformed image  612 . 
     The display unit  151  may transform and display the second transformed image  612  on the basis of a touch input applied to the second transformed image  612  that is displayed adjacent to the first image  510 . In addition, the display unit  151  may display the original state of the second transformed image  612  when a touch input applied to the second transformed image  612  is released. 
     According to an embodiment of the present invention, the control unit  180  may select a plurality of images that are not adjacent to one another and may transform and display a plurality of images selected together by applying a touch input to a transformed image that is displayed adjacent to one image. 
     A control method using a third transformed image corresponding to one image will be described with reference to  FIG. 8C . When one adjustment item is selected and then one image is selected on the basis of a user&#39;s touch input, the control unit  180  may control the display unit  151  to highlight the selected image. 
     Further, when another adjustment item is selected from the editing menu  501 , the control unit  180  controls the display unit  151  to display third and fourth transformed images  631  and  632 . The third and fourth transformed images  631  and  632  correspond to the selected two adjustment items. For example, when brightness and enlargement items are selected from the editing menu  501 , the third transformed image  631  may correspond to the brightness item, and the fourth transformed image  632  may correspond to the enlargement item. 
     The third and fourth transformed images  631  and  632  may have one intersection and extend in width and length directions of the display unit  151 . For example, the third and fourth transformed images  631  and  632  may be formed in the form of a scroll bar. 
     The third and fourth transformed images  631  and  632  may be formed to be longer than the width and the length of the selected image  510 . However, only the image  510  is transformed and displayed on the basis of the touch input applied to the third and fourth transformed images  631  and  632 . 
     Thus, a user may easily transform and display an image using the control image that formed to be long. 
       FIG. 9  is a conceptual view showing a control method for deleting a selected image using a control line. The display unit  151  displays the fifth control image  650 , and the fifth control image  650  is formed in the control region  510 ′ between the images  510 . The fifth control image  650  has the form of a plurality of line segments that intersect with one another. 
     When touch inputs are applied to two line segments that face each other of the fifth control image  650 , the control unit  180  selects an image  510  that is displayed between the two line segments. The touch inputs applied to the fifth control image  650  may correspond to touch inputs that are moved in a direction approaching each other. The control unit  180  controls the display unit  151  to display the image  510  as a transformed image  510 ′ on the basis of the touch inputs moved in a direction approaching to each other. The transformed image  510 ′ may be implemented in the form in which a paper is crumpled as the touch inputs applied to the two regions approach each other. In addition, the display unit  151  may transform a region of the fifth control image  650 , in which the touch input is applied, into a form in which the region is stretched, and display the transformed region. 
     When the both touch inputs applied to the fifth control image  650  are closer than a predetermined distance, the control unit  180  may control the memory  160  to delete the selected image  510 . In addition, the display unit  151  may limit display of the selected image  510  and change an arrangement of the remaining images that have been displayed on the display unit  151 . 
     According to an embodiment of the present invention, a user need not touch a separate graphic image in order to delete an image, can get a feeling that he/or she crushes the image, and may delete the image easily. 
       FIG. 10  is a conceptual view showing a control method for adjusting a display status of a frame of a video. The control unit  180  may control the display unit  151  to select a video file  520  and to display the selected video in addition to a plurality of frames that are divided into predetermined periods. First to fourth images  521 ,  522 ,  523 , and  524  are listed in one direction. 
     The display unit  151  displays a seventh image  670  in addition to the first to fourth frames  521 ,  522 ,  523 , and  524 . The seventh control image  670  may include first to fourth control lines  671 ,  672 ,  673 , and  674 . However, the number of control lines is not limited thereto. Respective control lines correspond to different display statuses. Fore example, the display statuses may include an effect, a brightness, an enlargement, a rotation, and so on. 
     The control unit  180  may adjust a display status of one of a plurality of frames on the basis of a touch input applied to one of the plurality of control lines. The control line may be divided into regions corresponding to the plurality of frames. Thus, the control unit  180  may select one of a plurality of frames on the basis of a touch input applied to one region of the control line. 
     When one framed is selected to be controlled, the control unit  180  controls the display unit  151  to adjust a display status of the selected frame on the basis of the touch input applied to the control line. 
     For example, the control unit  180  may control the display unit  151  to adjust the brightness to make the second frame  522  darker on the basis of a continuous touch input applied to a region corresponding to the second frame  522  of the second control line  672 . 
     Thus, a user may independently adjust display statuses of a plurality of frames included in a video file while comparing the frames with each other. 
       FIG. 11  is a conceptual view showing a control method for changing a display status of one frame on a screen information window where a plurality of images are displayed according to another embodiment of the present invention. 
     Referring to (a) and (b) of  FIG. 11 , when the image  510  is displayed on the entire display unit  151 , the control unit  180  controls the display unit  151  to reduce and display the image  510  on the basis of a touch input applied to the display unit  151 . 
     The display unit  151  displays the reduced image  510  at the center of the display unit  151  and displays first and second additional images  530  and  540  adjacent to the right and left of the image  510 , respectively. The display unit  151  may display only a portion of the first and second additional images  530  and  540 . 
     Eighth and ninth control images  680  and  690  are displayed in a control region  510 ′ adjacent to the image  510  and the first and second additional images  530  and  540 . In addition, the display unit  151  further displays eighth and ninth status indication point  681  and  691  corresponding to the eighth and ninth control images  680  and  690 , respectively. 
     For example, the eighth and ninth control images  680  and  690  may be formed in a control line adjacent to the top edge and the bottom edge of the image, and the eighth and ninth status indication points  681  and  691  may be displayed adjacent to a side edge of the image  510 . The eighth and ninth status indication points  681  and  691  denote degrees of display statuses that are adjusted by the eighth and ninth control images  680  and  690 , respectively. 
     The control unit  180  selects the image displayed at the center of the display unit  151  as an image having a display status to be controlled. The control unite  180  may display the first and second additional images  530  and  540  at the center of the display unit  151  on the basis of the touch input. In this case, the first and second additional images  530  and  540  is selected. 
     The control unit  180  may adjust a display status of the image  510  on the basis of a touch input applied to the eighth and ninth control images  680  and  690 . Thus, positions for displaying the eighth and ninth status indication points  681  and  691  are changed. 
     The display status of the selected image may be changed. Screen information including a plurality of images is not limited to that shown in the drawings. 
     That is, the user may select at least one image using a control space between images, and easily change a display status of the image by applying a continuous touch input to the control space. 
     Therefore, the user need not display a menu screen for changing one image and may adjust a display status of a selected image while comparing the image with other images. 
     According to an embodiment of the present invention, a touch sensing unit of the display unit receives a touch input applied to a control region between images while a plurality of images are displayed together. It is possible to select an image adjacent to the control region where the touch input is received and transform the selected image on the basis of a touch input scheme. 
     That is, it is possible to easily select one of the plurality images and to simply transform and display the selected image in a desired method without switching the screen. 
     In addition, a control image may be displayed between the plurality of images, thus allowing a user to easily recognize a touch region. The control image may be transformed in an elastic form according to a touch input of a user, thus providing the user with a feeling like flicking an elastic material. 
     As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
