       BACKGROUND 
       [0002]    Mobile devices can be used to provide wireless communication between users. In particular, a user of a mobile device can place a telephone call to a landline or to another user of a mobile device. As mobile device capability has advanced in recent years, mobile devices have increasingly become able to provide functionality in addition to wireless communication. For example, some mobile devices provide internet access and other functionality. Moreover, as additional functionality is provided by mobile devices, additional means of rendering can also be employed.

     DETAILED DESCRIPTION 
       [0031]      FIG. 1  is a schematic block diagram showing a configuration of a mobile communication terminal employing an image display apparatus according to an exemplary implementation. The mobile communication terminal  100  may be implemented in various forms, such as mobile phones, smart phones, notebook computers, digital broadcast terminals, Personal Digital Assistants (PDAs) or Portable Multimedia Player (PMPs). 
         [0032]    As shown in  FIG. 1 , the mobile communication terminal  100  includes 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 , and a power supply unit  190 .  FIG. 1  shows the mobile communication terminal  100  having various components, but it is understood that implementing all of the illustrated components is not a requirement. In particular, various implementations of the mobile communication terminal  100  may include greater or fewer components in configurations other than the configuration illustrated by  FIG. 1 . 
         [0033]    The wireless communication unit  110  can include one or more components that enable radio communication between the mobile communication terminal  100  and a wireless communication system or a network in which the mobile communication terminal is located. For example, the wireless communication unit 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 , and a location information module  115 . 
         [0034]    The broadcast receiving module  111  receives broadcast signals and/or broadcast associated information from an external broadcast management server or other network entity (not shown) via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits the same to a terminal. The broadcast associated information may refer to information associated with a broadcast channel, a broadcast program or a broadcast service provider. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, or other signals. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. 
         [0035]    The broadcast associated information may also be provided via a mobile communication network and, in this case, the broadcast associated information may be received by the mobile communication module  112 . The broadcast signal may exist in various forms. For example, broadcast associated information may be implemented according to various formats, such as electronic program guide (EPG) of digital multimedia broadcasting (DMB), and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H). 
         [0036]    The broadcast receiving module  111  may be configured to receive signals broadcast using various types of broadcast systems. In particular, the broadcast receiving module  111  may receive a digital broadcast using a digital broadcast system, such as multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®), integrated services digital broadcast-terrestrial (ISDB-T), or other broadcast systems. The broadcast receiving module  111  may be configured to be suitable for broadcast systems that provide a broadcast signal as well as the above-mentioned digital broadcast systems. Broadcast signals and/or broadcast-associated information received via the broadcast receiving module  111  may be stored in the memory  160 . 
         [0037]    The mobile communication module  112  may transmit and receive radio signals to and from at least one of a base station (e.g., access point or node), an external terminal (e.g., other user devices) and a server or other network entity. Such radio signals may include a voice call signal, a video call signal, or various types of data according to text and/or multimedia message transmission and/or reception. 
         [0038]    The wireless Internet module  113  supports wireless Internet access for the mobile communication terminal. This module may be internally or externally coupled to the terminal. Here, as the wireless Internet technique, a wireless local area network (WLAN), Wi-Fi, wireless broadband (WiBro), world interoperability for microwave access (WiMAX), high speed downlink packet access (HSDPA) may be used. The short-range communication module  114  is a module for supporting short range communications. Some examples of short-range communication technology include Bluetooth™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), and ZigBee™. 
         [0039]    The location information module  115  is a module for checking or acquiring a location (or position) of the mobile communication terminal or vehicle in which the mobile communication terminal is located. For example, the location information module  115  may be embodied using a Global Positioning System (GPS) module that receives location information from a plurality of satellites. Here, the location information may include coordinate information represented by latitude and longitude values. For example, the GPS module may measure time and distance with respect to three or more satellites so as to calculate a current location of the mobile communication terminal  100  according to trigonometry based on the measured time and distances. A method of acquiring distance and time information from three satellites and performing error correction with a single satellite may be used. In particular, the GPS module may acquire time and three-dimensional speed information as well as a latitude, longitude, and altitude from the location information received from the satellites. A Wi-Fi position system and/or hybrid positioning system may be used as the location information module  115 . 
         [0040]    The A/V input unit  120  is configured to receive an audio or video signal. The A/V input unit  120  may include a camera  121  and a microphone  122 . The camera  121  processes image data of still pictures or video obtained by an image capture device in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit  151  (or other visual output device). The image frames processed by the camera  121  may be stored in the memory  160  (or other storage medium) or transmitted via the wireless communication unit  110 . Two or more cameras  121  may be provided according to the configuration of the mobile communication terminal. 
         [0041]    The microphone  122  may receive sounds via a microphone in a phone call mode, a recording mode, a voice recognition mode, or other modes, and can process the received sounds into audio data. In implementations using mobile telephone systems, the processed audio data may be converted for output into a format transmittable to a mobile communication base station (or other network entity) via the mobile communication module  112 . The microphone  122  may implement various types of noise canceling or suppression algorithms to cancel or suppress noise or interference generated in the course of receiving and transmitting audio signals. 
         [0042]    The user input unit  130  may generate key input data from commands entered by a user to control various operations of the mobile communication terminal  100 . The user input unit  130  allows the user to enter various types of information, and may include a keypad, a dome switch, a touch pad (e.g., a touch sensitive member that detects changes in resistance, pressure, or capacitance due to being contacted) a jog wheel, a jog switch, or other input mechanisms. In particular, when the touch pad is overlaid on the display unit  151  in a layered manner, it may form a touch screen. 
         [0043]    The sensing unit  140  detects a current status or state of the mobile communication terminal  100 , such as an opened or closed state of the mobile communication terminal  100 , a location of the mobile communication terminal  100 , the presence or absence of user contact with the mobile communication terminal  100  (i.e., touch inputs), the orientation of the mobile communication terminal  100 , an acceleration or deceleration movement and direction of the mobile communication terminal  100 , or other input mechanisms so as to generate commands or signals for controlling the operation of the mobile communication terminal  100 . For example, when the mobile communication terminal  100  is implemented as a slide type mobile phone, the sensing unit  140  may sense whether the slide phone is opened or closed. In addition, the sensing unit  140  can detect whether or not the power supply unit  190  supplies power or whether or not the interface unit  170  is coupled with an external device. 
         [0044]    The interface unit  170  serves as an interface by which at least one external device may be connected with the mobile communication terminal  100 . For example, the external devices may include wired or wireless headset ports, an external power supply or battery charger 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, or earphone ports. Here, the identification module may be a memory chip or other element with memory or storage capabilities that stores various information for authenticating a user&#39;s authority for using the mobile communication terminal  100 . This information may include, for example, a user identity module (UIM), a subscriber identity module (SIM), or a universal subscriber identity module (USIM). 
         [0045]    In addition, the device having the identification module (referred to as the ‘identifying device’, hereinafter) may take the form of a smart card. Accordingly, the identifying device may be connected with the mobile communication terminal  100  via a port or other connection means. The interface unit  170  may be used to receive inputs (e.g., data, information, or power) from an external device and transfer the received inputs to one or more elements within the mobile communication terminal  100  or may be used to transfer data between the mobile communication terminal and an external device. 
         [0046]    The output unit  150  is configured to provide outputs in a visual, audible, and/or tactile manner (e.g., audio signal, video signal, alarm signal, or vibration signal). The output unit  150  may include the display unit  151 , an audio output module  152 , an alarm unit  153 , or other units. 
         [0047]    The display unit  151  may display information processed in the mobile terminal  100 . For example, when the mobile terminal  100  is in a phone call mode, the display unit  151  may display a User Interface (UI) or a Graphic User Interface (GUI) associated with a call or other communication (such as text messaging or multimedia file downloading). When the mobile terminal  100  is in a video call mode or image capturing mode, the display unit  151  may display a captured image and/or a received image, or a UI or GUI that shows videos or images and functions related thereto. 
         [0048]    The display unit  151  may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, or a three-dimensional (3D) display. The mobile terminal  100  may include two or more display units or other display means according to its particular desired functionality. For example, the mobile terminal may include both an external display unit (not shown) and an internal display unit (not shown). When the display unit  151  and the touch pad are overlaid in a layered manner to form a touch screen, the display unit  151  may function as both an input device and an output device. The touch sensor may, for example, have the form of a touch film, a touch sheet, or a touch pad. In some cases, touch sensors (or touch screens) can operate without physical contact. For example, touch screens operating on changed capacitance or other electrical characteristics may operate by the nearby presence of a finger or object with or without physical contact with the screen. As such, a “touch screen” may not actually require a touch for operation. 
         [0049]    The touch sensor may be configured to convert the pressure applied to a particular portion of the display unit  151  or a change in capacitance or other electrical characteristic generated at a particular portion of the display unit  151  into an electrical input signal. The touch sensor may be configured to detect a touch input pressure as well as a touch input position and a touch input area. When there is a touch input with respect to the touch sensor, the corresponding signal is sent to a touch controller (not shown). The touch controller processes the signal and transmits corresponding data to the controller  180 . Accordingly, the controller  180  can recognize a touched region of the display unit  151 . A proximity sensor  141  of the mobile communication terminal  100  will now be described with reference to  FIG. 2 . 
         [0050]      FIG. 2  illustrates a proximity touch. A proximity touch can, for example, refer to recognition of the pointer positioned to be close to the touch screen without being actually in contact with the touch screen. In addition, a proximity touch can also refer to other touch screen functionality, as discussed above. 
         [0051]    The proximity sensor  141  may be disposed within the mobile terminal covered by the touch screen or near the touch screen. The proximity sensor  141  can refer to a sensor for detecting the presence or absence of an object that accesses a certain detection surface or an object that exists nearby by using the force of electromagnetism or infrared rays without a mechanical contact. Thus, the proximity sensor  141  can have a longer life span than a contact type sensor and can be utilized for various purposes. 
         [0052]    Examples of a proximity sensor  141  include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror-reflection type photo sensor, an RF oscillation type proximity sensor, a capacitance type proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is an electrostatic type touch screen, an approach of the pointer can be detected based on a change in an electric field according to the approach of the pointer. For example, the touch sensor may be classified as a proximity sensor. 
         [0053]    In the following description, for the sake of brevity, recognition of the pointer positioned to be close to the touch screen without being contacted will be called a ‘proximity touch’, while recognition of actual contacting of the pointer on the touch screen will be called a ‘contact touch.’ In this case, the pointer being in the state of the proximity touch can indicate that the pointer is positioned to correspond vertically to the touch screen. 
         [0054]    The proximity sensor  141  detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch speed, a proximity touch time, a proximity touch position, or a proximity touch movement state), and information corresponding to the detected proximity touch operation and the proximity touch pattern can be outputted to the touch screen. 
         [0055]    The audio output module  152  may output audio data received from the wireless communication unit  110  or stored in the memory  160  in various modes. The modes may include a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, or other modes. Also, the audio output module  152  may provide audible outputs related to a particular function (e.g., a call signal reception sound or a message reception sound) performed in the mobile terminal  100 . The audio output module  152  may include a receiver, a speaker, or a buzzer. 
         [0056]    The alarm unit  153  outputs a signal for informing a user about an occurrence of an event of the mobile terminal  100 . Events generated in the mobile terminal may include receipt of a call, receipt of a message, or received key or touch inputs. In addition to video or audio signals, the alarm unit  153  may output signals in a different manner, for example, to inform a user about an occurrence of an event. The video or audio signals may be also outputted via the audio output module  152 , so the display unit  151  and the audio output module  152  may be classified as parts of the alarm unit  153 . 
         [0057]    A haptic module  154  generates various tactile effects the user may feel, such as, for example, vibration. The strength and pattern of the haptic module  154  can be controlled. For example, different vibrations may be combined to be outputted or sequentially outputted. Besides vibration, the haptic module  154  may generate various other tactile effects. The generated effects can include stimulation with a pin arrangement moving vertically 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, and the sense of cold or warmth using an element that can absorb or generate heat. In addition, the haptic module  154  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  154  may be provided according to the configuration of the mobile terminal  100 . 
         [0058]    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, or video) 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. 
         [0059]    The memory  160  can be implemented using any type of suitable storage medium, such as, for example, 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. 
         [0060]    The interface unit  170  can serve as an interface with external devices connected with the mobile terminal  100 . For example, the external devices may transmit data to an external device, receive and transmit power to elements of the mobile terminal  100 , or transmit internal data of the mobile terminal  100  to other devices.

This information may include a UIM, a SIM a USIM, or other information. 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 mobile communication terminal  100  via a port. The interface unit  170  may be used to receive inputs (e.g., data, information, or power) from an external device and transfer the received inputs to one or more elements within the mobile communication terminal  100  or may be used to transfer data between the mobile terminal and an external device. 
         [0062]    When the mobile communication 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 communication 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 communication terminal  100  therethrough. Various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile communication terminal  100  is properly mounted on the cradle. 
         [0063]    The controller  180  can control the general operations of the mobile communication terminal  100 . For example, the controller  180  can perform controlling and processing associated with voice calls, data communications, video calls, or other operations. 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 . Also, the controller  180  may perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images. The power supply unit  190  receives external power or internal power and supplies power required for operating respective elements and components under the control of the controller  180 . 
         [0064]    Various embodiments described herein may be implemented in a computer-readable medium using, for example, software, hardware, or a combination thereof.

Each software module may perform one or more functions or operations described herein. Software codes can be implemented by a software application written in any suitable programming language. The software codes may be stored in the memory  160  and executed by the controller  180 . The voice recognition module  182  recognizes a voice pronounced by the user and performs a corresponding function according to the recognized voice signal. 
         [0067]    A navigation session  300  applied to the mobile communication terminal  100  can be used in displaying a travel route.  FIG. 3  is a schematic block diagram showing a configuration of a vehicle navigation system. As shown in  FIG. 3 , a vehicle navigation system includes an information providing center  30  for providing traffic information and various data (e.g., programs, execution, and files). A telematics terminal  200  that is mounted within a vehicle, receives traffic information via a remote wireless communication network  20  and/or short-range wireless communication network, and provides a road guidance service based on a GPS signal received via a satellite  10  and the traffic information. 
         [0068]    The configuration of the telematics terminal  200  according to various implementations is described below with respect to  FIG. 4 .  FIG. 4  is a schematic block diagram showing a configuration of a telematics terminal  200 . As shown in  FIG. 4 , the telematics terminal  200  includes a main board  210  including a controller or CPU (Central Processing Unit)  212  for controlling the telematics terminal  200 , memory  213  for storing various information, a key controller  211  for controlling various key signals, and an LCD controller  214  for controlling an LCD. 
         [0069]    The memory  213  stores map information (map data) for displaying road guidance information on a digital map. Also, the memory  213  stores a traffic information collection and control algorithm for inputting traffic information according to a present condition of a road on which the vehicle is currently traveling . 
         [0070]    The main board  210  includes a Code Division Multiple Access(CDMA) module  206  and a GPS module  207 . The GPS module  207  can guide a location of the vehicle, receive a GPS signal for tracking a travel route from a start point to a destination, and transmit traffic information collected by the user as a GPS signal. The main board  210  can also include a CD deck  208  for reproducing a signal recorded in a CD (Compact Disk) and a gyro sensor  209 . The CDMA module  206  and the GPS module  207  transmit or receive signals via antennas  204  and  205 . 
         [0071]    A broadcast receiving module  222  is connected with the main board  210  and receives a broadcast signal via an antenna  223 . An LCD  201  under the control of the LCD controller  214 , a front board  202  under the control of the key controller  211 , and a camera  227  for capturing the interior and/or the exterior of a vehicle are connected to the main board  210  via an interface board  203 . The display unit  201  displays various video signals and character signals, and the front board  202  includes buttons for various key signal inputs and provides a key signal corresponding to a button selected by the user to the main board  210 . Also, the display unit  201  can include a proximity sensor and a touch sensor. In addition, the front board  202  can include a menu key for directly inputting traffic information. The menu key may be configured to be controlled by the key controller  211 . 
         [0072]    An audio board  217  is connected with the main board  210  and processes various audio signals. The audio board  217  includes a microcomputer  219  for controlling the audio board  217 , a tuner  218  for receiving a radio signal, a power source unit  216  for supplying power to the microcomputer  219 , and a signal processing unit  215  for processing various voice signals. Further, the audio board  217  includes a radio antenna  220  for receiving a radio signal and a tape deck  221  for reproducing an audio tape. The audio board  217  may further include a voice output unit  226  including, for example, an amplifier, for outputting a voice signal processed by the audio board  217 . 
         [0073]    The voice output unit  226  is connected to a vehicle interface  224 . Namely, the audio board  217  and the main board  210  are connected to the vehicle interface  224 . A hands-free unit  225   a  for inputting a voice signal, an airbag  225   b  configured for the security of a passenger, and a speed sensor  225   c  for detecting the speed of the vehicle, may be connected to the vehicle interface  224 . The speed sensor  225   c  calculates a vehicle speed and provides the calculated vehicle speed information to the CPU  212 . 
         [0074]    The display unit  201  detects a proximity touch within a display window via a proximity sensor. For example, when a pointer (e.g., user&#39;s finger or stylus) becomes adjacent to or touches the display unit  201 , the display unit  201  detects the position of the proximity touch and outputs position information corresponding to the detected position to the CPU  212 . A voice recognition module  301  recognizes a voice pronounced by the user and performs a corresponding function according to the recognized voice signal. 
         [0075]    The navigation session  300  applied to the telematics terminal  200  generates road guidance information based on the map data and current location information of the vehicle and provides the generated road guidance information to a user. The vehicle navigation session  300  applied to the telematics terminal  200  displays a travel route on map data, and when the location of the mobile communication terminal  100  is within a pre-set distance from a dead zone included in the travel route, the vehicle navigation session  300  automatically forms a wireless network with a terminal (e.g., a vehicle navigation device) mounted within a nearby vehicle and/or a mobile communication terminal carried around by a nearby pedestrian through radio communication (e.g., a short range wireless communication network), in order to receive location information from one or more of the terminal mounted within the nearby vehicle and the mobile communication terminal carried around by the nearby pedestrian. 
         [0076]      FIG. 5  is a schematic block diagram showing a configuration of a data display apparatus. The data display apparatus may be applicable to smart phones, notebook computers, digital broadcasting terminals, PDAs, PMPs, desktop computers, and the mobile communication terminal  100  and the telematics terminal  200 . 
         [0077]    As shown in  FIG. 5 , a data display device  500  includes a display unit  403 , a storage unit  402  for storing data (e.g., multimedia data) and information related to the data, a controller  401 . The controller  401  can be configured to enable display of overview information of first data selected by the user and display of information related to the first data in a map form on the display unit  402  when an icon indicating information in relation to the first data is selected by the user. The data display apparatus  400  may download the data (e.g., multimedia data) and information related to the data from a server  500  via a communication unit  404 . 
         [0078]      FIG. 6  is a flow chart illustrating a first process for data display. Initially, first data is selected from among a plurality of data items (S 11 ). Next, overview information of the first data is displayed (S 12 ). In particular, when first data is selected by the user from among data items (e.g., multimedia data) displayed on the display unit  403 , the controller  401  reads overview information of the first data from the storage unit  402  and displays the overview information on the display unit  403 . Here, the first data may be multimedia data such as movie data, music data, photo data, or music album data. The overview information may be overview information regarding movies, music, photos, or other information. 
         [0079]      FIGS. 7 and 8  are overviews of display screens illustrating selection of data. As shown in  FIG. 7 , the controller  401  displays the multimedia data (e.g., movie, music, or photos) on the display unit  403 , and when a movie is selected by the user from among the displayed multimedia data, the controller  401  searches one or more of a hard disk drive (HDD), a universal serial bus (USB), a digital living network alliance (DLNA), a common Internet file system (CIFS), and an online server for the selected movie and displays retrieved movie data on the display unit  403 . 
         [0080]    As shown in  FIG. 8 , the controller  401  displays movie data which has been searched from one or more of the hard disk drive (HDD), the universal serial bus (USB), the digital living network alliance (DLNA), the common Internet file system (CIFS), and the online server on the display unit  403 . When first data (e.g., data regarding the movie “Dark Knight”)  8 - 1  is selected by the user from the movie data displayed on the display unit  403 , the controller  401  reads overview information of the first data and displays the read overview information on the display unit  403 . 
         [0081]    Then, it is determined whether a relation map icon that is displayed on overview information has been selected (S 13 ). Specifically, the controller  401  determines whether or not an icon included in the overview information is selected by the user. The icon can be displayed together with the overview information on the display unit  430  and can indicate information related to the first data. 
         [0082]    Hereinafter, the overview information of the first data and the icon indicating the information related to the first data will now be described with reference to  FIG. 9 . As shown in  FIG. 9 , when the first data  9 - 1  (e.g., a poster or representative image of “Dark Knight”) is selected by the user from among data displayed on the display unit  403 , the controller  401  reads overview information of the first data from the storage unit  402  and displays the read overview information on the display unit  403 . The overview information may include information about a director of the movie, information about actors, information about a writer, information about a release date, information about a genre, awards information, NewsDesk, or other information. 
         [0083]    The overview information may further include almighty search icon. When the almighty search icon is selected by the user, the controller  401  searches movie data (e.g., “Dark Knight”) corresponding to the first data  9 - 1  from the storage unit  402  or the server  500  and reproduces (i.e., plays) the searched movie data. Also, the controller  401  determines whether or not an icon  9 - 2  displayed on the overview information screen image and indicating information related to the “Dark Knight”  9 - 1  has been selected. Here, the icon  9 - 2  refers to an icon searching and indicating various representative image information related to the data (e.g., “Dark Knight”  9 - 1 ) selected by the user. 
         [0084]    Next, information related to the first data is searched (S 14 ). When the icon included in the overview information is selected by the user, the controller  401  searches the storage unit  402  for information related to the first data. Also, searched information is displayed in map form centering around the first data. That is, when information related to the first data is searched from the storage unit  402 , the controller  401  displays the searched information related to the first data in a map form centering around the first data on the display unit  403 . 
         [0085]      FIG. 10  illustrates information related to the first data according to various implementations. As shown in  FIG. 10 , when the information related to the first data  9 - 1  is searched from the storage unit  402 , the controller  401  displays the searched information related to the first data in a map form centering around the first data  9 - 1  on the display unit  403 . For example, the controller  401  may display representative images (e.g., poster images of films in which Heath Ledger acted) representing first actor information related to the representative image  9 - 1  of “Dark Knight” in a row on the display unit  403  such that they are gradually reduced in size toward a first direction (e.g., at 45 degrees clockwise) from the poster image  9 - 1  of “Dark Knight.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films in which Heath Ledger acted) in the first direction such that the more recent the films, the closer they are to the poster image  9 - 1  displayed at the center of the searched information related to the first data. 
         [0086]    The controller  401  may display representative images (e.g., poster images of films in which Christian Bale acted) representing second actor information related to the representative image  9 - 1  of “Dark Knight” in a row on the display unit  403  such that they are gradually reduced in size toward a second direction (e.g., at 135 degrees clockwise) from the poster image  9 - 1  of “Dark Knight.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films in which Christian Bale acted) in the second direction such that the more recent the films, the closer they are to the poster image  9 - 1  of “Dark Knight” displayed at the center of the searched information related to the first data. 
         [0087]    The controller  401  may display poster images representing series information (e.g., “Batman” series 1, 2, 3, . . . ) related to the poster image  9 - 1  of “Dark Knight” in a row on the display unit  403  such that they are gradually reduced in size toward a third direction (e.g., at 225 degrees clockwise) from the poster image  9 - 1  of “Dark Knight.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the “Batman” series films) in the third direction such that the more recent the films, the closer they are to the poster image  9 - 1  of “Dark Knight” displayed at the center of the searched information related to the first data. 
         [0088]    The controller  401  may display representative images (e.g., poster images of films produced by Christopher Nolan) representing director information related to the representative (poster) image  9 - 1  of “Dark Knight” in a row on the display unit  403  such that they are gradually reduced in size toward a fourth direction (e.g., at 315 degrees clockwise) from the poster image  9 - 1  of “Dark Knight.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films produced by Christopher Nolan) in the fourth direction such that the more recent the films, the closer they are to the poster image  9 - 1  of “Dark Knight” displayed at the center of the searched information related to the first data. 
         [0089]    Here, the controller  401  may display first actor information, second actor information, series information, and director information in various directions according to a setting of a designer, and may further display writer information, genre information, awards information, and other information related to the first data. Also, the controller  401  may download information (e.g., actor information, series information, director information, writer information, genre information, or award information) related to the first data from the server  500  via the communication unit  400  or from an external storage medium (e.g., a USB memory). 
         [0090]    Thereafter, it is determined whether first data that is displayed on information in map form has been selected (S 16 ). If so, overview information of the first data is displayed (S 17 ). More specifically, the controller  401  may determine whether or not the first data  9 - 1  within the information displayed in the map form has been selected again by the user. When the first data  9 - 1  displayed on the information displayed in the map form is selected by the user, the controller  401  displays overview information of the first data  9 - 1  on the display unit  403 . 
         [0091]    In the above description, representative images are described as being within rows in first through fourth directions defined in terms of degrees. This description is exemplary as, the representative images may be placed on a purely linearly axis (as shown in  FIG. 10 ) in specified degree angles or may be placed along a non-linear axis. Whether linear or non-linear in nature, the axis defines the points in which the representative images are placed on the screen. For example, the first through fourth rows may be placed along axes that are curved or spiral in nature. That is, the representative images may be placed at points along a spiral direction away from a central image. Also, the first through fourth rows may be placed along a circular axis, a three-dimensional axis, or an axis with another shape. In addition, various combinations and axes may be used. For example, in one implementation, the first and second rows are linear and the third and fourth rows are spiral. 
         [0092]    For simplicity of description, the further implementations described below similarly refer to implementations using linear axes. However, the use of various types of non-linear axes described above also applies to the description below. For example, the rows in  FIGS. 12-14  and  17 - 19  need not be linear and may be, for example, spiral, circular, three-dimensional, or a combination thereof. 
         [0093]      FIG. 11  is a flow chart of a second process for data display. Initially, when the first data is selected by the user from among data (e.g., multimedia data) displayed on the display unit  403 , the controller  401  reads the overview information of the first data from the storage unit  402  and displays the read overview information on the display unit  403 . The controller  401  determines whether or not an icon included in the overview information has been selected by the user. When the icon included in the overview information is selected by the user, the controller  401  searches information related to the first data from the storage unit  402 . 
         [0094]    Search information is displayed in map form centering around first data (S 21 ). That is, when information related to the first data is searched from the storage unit  402 , the controller  401  displays the searched information related to the first data in a map form on the display unit  403 , centering around the first data. Then, whether second data has been selected from among searched information is determined (S 22 ). For example, the controller  401  determines whether or not second data has been selected by the user from among the information related to the first data (S 22 ). If so, information related to the second data is searched (S 23 ). For example, when the second data is selected by the user from among the information related to the first data, the controller  401  searches information related to the second data from the storage unit  402 . 
         [0095]    Thereafter, searched information is displayed in map form centering around the second data (S 24 ). More specifically, when information related to the second data is searched from the storage unit  402 , the controller  401  displays the searched information related to the second data in a map form on the display unit  403 , centering around the second data. 
         [0096]    The information related to the second data will now be described with reference to  FIGS. 12 and 13 .  FIGS. 12 and 13  are overviews of display screens illustrating information related to a second data item. As shown in  FIG. 12 , when information related to second data  12 - 1  is searched from the storage unit  402 , the controller  401  displays the searched information related to the second data in a map form on the display unit  403 , centering on the second data  12 - 1 . 
         [0097]    As shown in  FIG. 13 , the controller  401  may display representative images (e.g., poster images of films in which Sam Worthington acted) representing first actor information related to a representative image  12 - 1  of “Terminator” in a row on the display unit  403  such that they are gradually reduced in size toward a first direction (e.g., at 45 degrees clockwise) from the poster image  12 - 1  of “Terminator.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films in which Sam Worthington acted) in the first direction such that the more recent the films, the closer they are to the poster image  12 - 1  of Terminator displayed at the center of the searched information related to the second data. 
         [0098]    The controller  401  may display representative images (e.g., poster images of films in which Christian Bale acted) representing second actor information related to the representative image  12 - 1  of “Terminator” in a row on the display unit  403  such that they are gradually reduced in size toward a second direction (e.g., at 135 degrees clockwise) from the poster image  12 - 1  of “Terminator.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films in which Christian Bale acted) in the second direction such that the more recent the films, the closer they are to the poster image  12 - 1  of “Terminator” displayed at the center of the searched information related to the second data. 
         [0099]    The controller  401  may display poster images representing series information (e.g., “Terminator” series 1, 2, 3, . . . ) related to the poster image  12 - 1  of “Terminator” in a row on the display unit  403  such that they are gradually reduced in size toward a third direction (e.g., at 225 degrees clockwise) from the poster image  12 - 1  of “Terminator.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the “Terminator” series films) in the third direction such that the more recent the films, the closer they are to the poster image  12 - 1  of “Terminator” displayed at the center of the searched information related to the second data. 
         [0100]    The controller  401  may display representative images (e.g., poster images of films produced by Joseph McGinty Nichol) representing producer information related to the representative image  12 - 1  of “Terminator” a row on the display unit  403  such that they are gradually reduced in size toward a fourth direction (e.g., at 315 degrees clockwise) from the poster image  12 - 1  of “Terminator.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant films (e.g., the films produced by Joseph McGinty Nichol) in the fourth direction such that the more recent the films, the closer they are to the poster image  12 - 1  of “Terminator” displayed at the center of the searched information related to the second data. 
         [0101]    Here, the controller  401  may display first actor information, second actor information, series information, and producer information in various directions according to a setting of a designer, and may further display writer information, genre information, awards information, or other information related to the second data. 
         [0102]    Thereafter, it is determined whether second data that is displayed on information in map form has been selected (S 25 ). In particular, the controller  401  may determine whether or not the second data  12 - 1  displayed on the information displayed in the map form has been selected again by the user. If so, overview information is second data is displayed (S 26 ). That is, when the second data  12 - 1  displayed on the information displayed in the map form is selected by the user, the controller  401  displays overview information of the second data  12 - 1  on the display unit  403 . 
         [0103]    A method of displaying overview information of the second data when the second data is selected again by the user will now be described with reference to  FIG. 14 .  FIG. 14  is an overview of display screens illustrating overview information. As shown in  FIG. 14 , the controller  401  determines whether or not the second data  12 - 1  displayed on the information that is displayed in the map form has been selected again by the user. When the second data  12 - 1  is selected by the user, the controller  401  displays overview information of the second data  12 - 1  on the display unit  403 . The overview information may include a poster image of “Terminator” and director information, actor information, writer information, release date information, genre information, awards information, NewsDesk, or other information. 
         [0104]    The overview information further includes an almighty search icon. When the almighty search icon  14 - 1  is selected by the user, the controller  401  searches movie data (e.g., “Terminator”) corresponding to the second data  12 - 1  from the storage unit  402  or from the server  500 , and reproduces (plays) the searched movie data. 
         [0105]      FIG. 15  is a flow chart illustrating a third process for data display. Initially, first data is selected from among music album data (S 31 ). Then, overview information of the first data is displayed (S 32 ). In particular, when the first data (e.g., first music data) is selected from the data (e.g., music data) displayed on the display unit  403 , the controller  401  reads overview data of the first data from the storage unit  402  and displays the read overview information on the display unit  403 . Here, the first data may be multimedia data, such as photo data or music data. The overview information may be overview information regarding specific music selected by the user, or overview information regarding photo/music data. 
         [0106]    Next, it is determined whether a relational map icon that is displayed on overview information has been selected (S 33 ). Specifically, the controller  401  determines whether or not the icon (e.g., the relation map icon) included in the overview information has been selected by the user. The icon is displayed on the display unit  403  together with the overview information and indicates information related to the first data. 
         [0107]    Hereinafter, icons for indicating the overview information of the first data (music data) and the information related to the first data (music data) will now be described with reference to  FIG. 16 .  FIG. 16  is an overview of a display screen illustrating overview information. As shown in  FIG. 16 , when first music data  16 - 1  (e.g., a poster or representative image) of “Crazy In Love” of Beyonce is selected by the user from among a plurality of music data (e.g., posters or music representative images) displayed on the display unit  403 , the controller  401  reads overview information of the first music data from the storage unit  402  and displays the read overview information on the display unit  403 . The overview information may include information about the singer, the album, the lyrics, a release date, genre, NewsDesk of the title of the song “Crazy In Love.” 
         [0108]    The overview information further includes an almighty search icon. When the almighty search icon is selected by the user, the controller  401  searches a music file (e.g., “Crazy In Love”) corresponding to the first data  16 - 1  from the storage unit  402  or from the server  500 , and reproduces (plays) the searched music data. In addition, the controller  401  determines whether or not an icon  16 - 2  for indicating information displayed on the overview information and related to the title of the song “Crazy In Love”  16 - 1  has been selected. 
         [0109]    Next, information related to the first data is searched (S 34 ). Then, searched information is displayed in map form centering around the first data (S 35 ). Specifically, when an icon (e.g., a relation map icon) included in the overview information is selected by the user, the controller  401  searches information related to the first music data from the storage unit  402 . When the information related to the first music data is searched from the storage unit  402 , the controller  401  displays the information related to the searched first data in a map form, centering around the first data, on the display unit  403 . 
         [0110]    Hereinafter, the information related to the first music data will now be described with reference to  FIG. 17 .  FIG. 17  is an overview of a display screen illustrating information related to a first music data item. As shown in  FIG. 17 , when information related to the first music data  16 - 1  is searched from the storage unit  402 , the controller  401  displays the searched information related to the first music data in a map form, centering around the first data  16 - 1 , on the display unit  16 - 1 . For example, the controller  401  displays the representative images (e.g., the poster images of a first music album and a second music album) representing album information related to the representative image  16 - 1  in a row on the display unit  403  such that they are gradually reduced in size toward a first direction (e.g., at 45 degrees clockwise) from the poster image  16 - 1  of “Crazy In Love.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant music albums in the first direction such that the more recent the music albums, the closer they are to the poster image  16 - 1  displayed at the center of the searched information related to the music data. 
         [0111]    The controller  401  may display representative images (e.g., poster images of songs sung by Beyonce) representing artist (e.g., singer) information related to the representative image  16 - 1  of “Crazy In Love” in a row on the display unit  403  such that they are gradually reduced in size toward a second direction (e.g., at 135 degrees clockwise) from the poster image  16 - 1  of “Crazy In Love.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant title of songs in the second direction such that the more recent the songs, the closer they are to the poster image  16 - 1  of “Crazy In Love” displayed at the center of the searched information related to the first data. 
         [0112]    The controller  401  may display poster images representing music video information related to the poster image  16 - 1  of “Crazy In Love” in a row on the display unit  403  such that they are gradually reduced in size toward a third direction (e.g., at 225 degrees clockwise) from the poster image  16 - 1  of “Crazy In Love.” Namely, the controller  401  sequentially displays the poster images corresponding to the relevant music video in the third direction such that the more recent the music video, the closer they are to the poster image  16 - 1  of “Crazy In Love” displayed at the center of the searched information related to the first data. Here, the controller  401  may download the music video from a website, such as www.youtube.com. 
         [0113]    The controller  401  may display representative images representing photo information (e.g., photo images of the single of “Crazy In Love”) related to the representative (poster) image  16 - 1  of “Crazy In Love” in a row on the display unit  403  such that they are gradually reduced in size toward a fourth direction (e.g., at 315 degrees clockwise) from the poster image  16 - 1  of “Crazy In Love.” Namely, the controller  401  sequentially displays the poster images (here, the poster images may be the photo images) corresponding to the relevant photo images in the fourth direction such that the more recent the photo images, the closer they are to the poster image  16 - 1  of “Crazy In Love” displayed at the center of the searched information related to the first data. Here, the controller  401  may download the photo images stored in the server  500  through a website, such as www.picassa.com. 
         [0114]    Here, the controller  401  may display the album information, artist information, music video information, and the photo information in various directions according to a designer&#39;s setting, and may further display composer information, genre information, or other information related to the first data in various forms. Also, the controller  401  may download information (e.g., album information, artist information, music video information, or photo information) related to the first data from the server  500  or an external storage medium (e.g., a USB memory) through the communication unit  404 . 
         [0115]    Thereafter, it is determined whether the first data that is displayed on information in map form has been selected (S 36 ). If so, overview information of the first data is displayed (S 37 ). For example, the controller  401  determines whether or not the first data  16 - 1  displayed on the information displayed in the map form is selected again by the user. When the first data  16 - 1  displayed on the information displayed in the map form is selected by the user, the controller  401  displays overview information of the first data  16 - 1  on the display unit  403 . Meanwhile, when a poster image representing first music video information is selected by the user from among the information displayed in the map form, the controller  401  receives the first music video data through the storage unit  402  or the communication unit  404 , and reproduces (plays) the received first music video data. 
         [0116]    Hereinafter, a method of receiving the first music video data through the storage unit  402  or the communication unit  404  and reproducing the received first music video data when the poster image representing the first music video information is selected by the user will now be described with reference to  FIG. 18 .  FIG. 18  is an overview of display screens illustrating a method of reproducing music video. As shown in  FIG. 18 , when a poster image  18 - 1  representing the first music video information is selected by the user, the controller  401  receives first music video data linked to the poster image  18 - 1  through the storage unit  402  or the communication unit  404  and reproduces (i.e., plays) the received first music video data. In addition, when the first music video data is reproduced, if a return relation map icon displayed on the screen for reproducing the first music video data is selected by the user, the controller  401  displays information related to the first music data again on the display unit  403 . 
         [0117]    Hereinafter, the method of receiving first photo data through the storage unit  402  or the communication unit  404  and displaying the received first photo data when a poster image representing first photo information is selected by the user from among information displayed in the map form will now be described with reference to  FIG. 19 .  FIG. 19  is an overview of a display screen illustrating a method of displaying a photo image. As shown in  FIG. 19 , when a poster image  19 - 1  representing the first photo information is selected by the user, the controller  401  receives first photo data linked to the poster image  19 - 1  through the storage unit  402  or the communication unit  404 , and displays the received first photo data. When the first photo data linked to the poster image  19 - 1  is displayed, the controller  401  reproduces music corresponding to the photo data. Here, the controller  401  may display the first photo data in the form of a slide show. For example, in displaying the first photo data in the form of a slide show, the controller  401  may set a display time duration of each photo image such that it is the same as a reproduction time duration of music related to each photo image. 
         [0118]    In addition, when the first photo data is displayed, if a return relation map icon displayed on the display screen for displaying the first photo data is selected by the user, the controller  401  may display the information related to the first music data again on the display unit  403 . 
         [0119]    As described above, an apparatus and method for displaying data provides various functionality. This functionality can include the following description. 
         [0120]    That is, first, when the first data is selected from among a plurality of data items, overview information of the selected first data is displayed on the display unit, and when an icon included in the overview information and indicating information related to the first data is selected, information related to the first data is displayed in a map form on the display unit. Thus, the user can easily select data. 
         [0121]    Second, when the first data is selected from among a plurality of data items, overview information of the selected first data is displayed on the display unit, and when an icon included in the overview information and indicating information related to the first data is selected, information related to the first data is displayed in a map form on the display unit. Thus, information related to the data selected by the user can be intuitively checked. 
         [0122]    As the above description may be implemented in various forms without departing from the characteristics thereof, it should also be understood that the above-described implementations 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.
