     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a mobile terminal, and more particularly, to a mobile terminal and controlling method thereof. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for facilitating a terminal to be used in further consideration of user&#39;s convenience. 
     Discussion of the Related Art 
     A mobile terminal is a device which may be configured to perform various functions. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files and outputting music via a speaker system, and displaying images and video on a display. Some terminals include additional functionality which supports game playing, while other terminals are also configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of contents, such as videos and television programs. 
     Generally, terminals can be classified into mobile terminals and stationary terminals according to a presence or non-presence of mobility. And, the mobile terminals can be further classified into handheld terminals and vehicle mount terminals according to availability for hand-carry. 
     There are ongoing efforts to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components which form the mobile terminal. 
     When a photo is taken using a camera built in a terminal, an image corresponding to a timing of pressing a photographing button is saved in general. In case of editing the saved image, it is able to edit the image acquired by the photographing button using a photo editing function installed on the terminal or a photo editing application downloaded to the terminal. 
     Recently, a panoramic photo function of creating a panoramic photo in a manner of acquiring several images and then synthesizing them into a single photo has been introduced. However, the panoramic photo function just provides an image created in a manner of synthesizing several photos.

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. 
     In the following description, the above elements of the mobile terminal  100  are explained in sequence. 
     First of all, the wireless communication unit  110  typically includes one or more components which permits wireless communication between the mobile terminal  100  and a wireless communication system or network within which the mobile terminal  100  is located. For instance, the wireless communication unit  110  can include a broadcast receiving module  111 , a mobile communication module  112 , a wireless internet module  113 , a short-range communication module  114 , a position-location module  115  and the like. 
     The broadcast receiving module  111  receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel 
     The broadcast channel may include a satellite channel and a terrestrial channel. 
     The broadcast managing server generally refers to a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which is provided with a previously generated broadcast signal and/or broadcast associated information and then transmits the provided signal or information to a terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. 
     At least two broadcast receiving modules  111  can be provided to the mobile terminal  100  in pursuit of simultaneous receptions of at least two broadcast channels or broadcast channel switching facilitation. 
     The broadcast associated information includes information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. And, the broadcast associated information can be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module  112 . 
     The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H). 
     The broadcast receiving module  111  may be configured to receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), DVB-CBMS, OMA-BCAST, the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module  111  can be configured suitable for other broadcasting systems as well as the above-explained digital broadcasting systems. 
     The broadcast signal and/or broadcast associated information received by 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 one or more network entities (e.g., base station, external terminal, server, etc.) via a mobile network such as GSM (Global System for Mobile communications), CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA) and so on. Such wireless signals may represent audio, video, and data according to text/multimedia message transceivings, among others. 
     The wireless internet module  113  supports Internet access for the mobile terminal  100 . This module may be internally or externally coupled to the mobile terminal  100 . In this case, the wireless Internet technology can include WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), GSM, CDMA, WCDMA, LTE (Long Term Evolution) etc. 
     Wireless internet access by Wibro, HSPDA, GSM, CDMA, WCDMA, LTE or the like is achieved via a mobile communication network. In this aspect, the wireless internet module  113  configured to perform the wireless internet access via the mobile communication network can be understood as a sort of the mobile communication module  112 . 
     The short-range communication module  114  facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few. 
     The position-location module  115  identifies or otherwise obtains the location of the mobile terminal  100 . If desired, this module may be implemented with a global positioning system (GPS) module. 
     According to the current technology, the GPS module  115  is able to precisely calculate current 3-dimensional position information based on at least one of longitude, latitude and altitude and direction (or orientation) by calculating distance information and precise time information from at least three satellites and then applying triangulation to the calculated information. Currently, location and time informations are calculated using three satellites, and errors of the calculated location position and time informations are then amended using another satellite. Besides, the GPS module  115  is able to calculate speed information by continuously calculating a real-time current location. 
     Referring to  FIG. 1 , the audio/video (A/V) input unit  120  is configured to provide audio or video signal input to the mobile terminal  100 . As shown, the A/V input unit  120  includes a camera  121  and a microphone  122 . The camera  121  receives and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. And, the processed image frames can be displayed on the display  151 . 
     The image frames processed by the camera  121  can be stored in the memory  160  or can be externally transmitted via the wireless communication unit  110 . Optionally, at least two cameras  121  can be provided to the mobile terminal  100  according to environment of usage. 
     The microphone  122  receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module  112  in case of a call mode. The microphone  122  typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal. At least two microphones  122  may be provided. For instance, in case that the at least two microphones  122  exist, one of the two microphones  122  is slanted to one side (e.g., a left side) in the mobile terminal  100 , while the other is slanted to another side (e.g., a right side) in the mobile terminal  100 . 
     The user input unit  130  generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, etc. 
     The sensing unit  140  provides sensing signals for controlling operations of the mobile terminal  100  using 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  100 , relative positioning of components (e.g., a display and keypad) of the mobile terminal  100 , a change of position of the mobile terminal  100  or a component of the mobile terminal  100 , a presence or absence of user contact with the mobile terminal  100 , orientation or acceleration/deceleration of the mobile terminal  100 , and free-falling of the mobile terminal  100 . As an example, consider the mobile terminal  100  being configured as a slide-type mobile terminal. In this configuration, the sensing unit  140  may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include 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. And, the sensing unit  140  can include a proximity sensor  141 . 
     The output unit  150  generates outputs relevant to the senses of sight, hearing, touch and the like. And, the output unit  150  includes the display  151 , an audio output module  152 , an alarm unit  153 , a haptic module  154 , a projector module  155  and the like. 
     The display  151  is typically implemented to visually display (output) information associated with the mobile terminal  100 . For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal  100  is in a video call mode or a photographing mode, the display  151  may additionally or alternatively display images which are associated with these modes, the UI or the GUI. 
     The display module  151  may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal  100  may include one or more of such displays. 
     Some of the above displays can be implemented in a transparent or optical transmittive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display  151  can be implemented in the optical transmittive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display  151  of the terminal body. 
     At least two displays  151  can be provided to the mobile terminal  100  in accordance with the implemented configuration of the mobile terminal  100 . For instance, a plurality of displays can be arranged on a single face of the mobile terminal  100  in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal  100 . 
     In case that the display  151  and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display  151  as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like. 
     The touch sensor can be configured to convert a pressure applied to a specific portion of the display  151  or a variation of a capacitance generated from a specific portion of the display  151  to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size. 
     If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller  180 . Therefore, the controller  180  is able to know whether a prescribed portion of the display  151  is touched. 
     Referring to  FIG. 1 , a proximity sensor ( 141 ) can be provided to an internal area of the mobile terminal  100  enclosed by the touchscreen or around the touchscreen. The proximity sensor is the sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor has durability longer than that of a contact type sensor and also has utility wider than that of the contact type sensor. 
     The proximity sensor can include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor and the like. In case that the touchscreen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of electric field according to the proximity of the pointer. In this case, the touchscreen (touch sensor) can be classified as the proximity sensor. 
     The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). And, information corresponding to the detected proximity touch action and the detected proximity touch pattern can be outputted to the touchscreen. 
     The audio output module  152  functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode and the like to output audio data which is received from the wireless communication unit  110  or is stored in the memory  160 . During operation, the audio output module  152  outputs audio relating to a particular function (e.g., call received, message received, etc.). The audio output module  152  is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof. 
     The alarm unit  153  is output a signal for announcing the occurrence of a particular event associated with the mobile terminal  100 . Typical events include a call received event, a message received event and a touch input received event. The alarm unit  153  is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be outputted via the display  151  or the audio output unit  152 . Hence, the display  151  or the audio output module  152  can be regarded as a part of the alarm unit  153 . 
     The haptic module  154  generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module  154 . Strength and pattern of the vibration generated by the haptic module  154  are controllable. For instance, different vibrations can be outputted in a manner of being synthesized together or can be outputted in sequence. 
     The haptic module  154  is able to generate various tactile effects as well as the vibration. For instance, the haptic module  154  generates the effect attributed to the arrangement of pins vertically moving against a contact skin surface, the effect attributed to the injection/suction power of air though an injection/suction hole, the effect attributed to the skim over a skin surface, the effect attributed to the contact with electrode, the effect attributed to the electrostatic force, the effect attributed to the representation of hold/cold sense using an endothermic or exothermic device and the like. 
     The haptic module  154  can be implemented to enable a user to sense the tactile effect through a muscle sense of finger, arm or the like as well as to transfer the tactile effect through a direct contact. Optionally, at least two haptic modules  154  can be provided to the mobile terminal  100  in accordance with the corresponding configuration type of the mobile terminal  100 . 
     The projector module  155  is the element for performing an image projector function using the mobile terminal  100 . And, the projector module  155  is able to display an image, which is identical to or partially different at least from the image displayed on the display unit  151 , on an external screen or wall according to a control signal of the controller  180 . 
     In particular, the projector module  155  can include a light source (not shown in the drawing) generating light (e.g., laser) for projecting an image externally, an image producing means (not shown in the drawing) for producing an image to output externally using the light generated from the light source, and a lens (not shown in the drawing) for enlarging to output the image externally in a predetermined focus distance. And, the projector module  155  can further include a device (not shown in the drawing) for adjusting an image projected direction by mechanically moving the lens or the whole module. 
     The projector module  155  can be classified into a CRT (cathode ray tube) module, an LCD (liquid crystal display) module, a DLP (digital light processing) module or the like according to a device type of a display means. In particular, the DLP module is operated by the mechanism of enabling the light generated from the light source to reflect on a DMD (digital micro-mirror device) chip and can be advantageous for the downsizing of the projector module  151 . 
     Preferably, the projector module  155  can be provided in a length direction of a lateral, front or backside direction of the mobile terminal  100 . And, it is understood that the projector module  155  can be provided to any portion of the mobile terminal  100  according to the necessity thereof. 
     The memory unit  160  is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal  100 . Examples of such data include program instructions for applications operating on the mobile terminal  100 , contact data, phonebook data, messages, audio, still pictures (or photo), moving pictures, etc. And, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia) can be stored in the memory unit  160 . Moreover, data for various patterns of vibration and/or sound outputted in case of a touch input to the touchscreen can be stored in the memory unit  160 . 
     The memory  160  may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory, XD memory, etc.), or other similar memory or data storage device. And, the mobile terminal  100  is able to operate in association with a web storage for performing a storage function of the memory  160  on Internet. 
     The interface unit  170  is often implemented to couple the mobile terminal  100  with external devices. The interface unit  170  receives data from the external devices or is supplied with the power and then transfers the data or power to the respective elements of the mobile terminal  100  or enables data within the mobile terminal  100  to be transferred to the external devices. The interface unit  170  may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, an earphone port and/or the like. 
     The identity module is the chip for storing various kinds of information for authenticating a use authority of the mobile terminal  100  and can include User Identify Module (UIM), Subscriber Identify Module (SIM), Universal Subscriber Identity Module (USIM) and/or the like. A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectible to the mobile terminal  100  via the corresponding port. 
     When the mobile terminal  110  is connected to an external cradle, the interface unit  170  becomes a passage for supplying the mobile terminal  100  with a power from the cradle or a passage for delivering various command signals inputted from the cradle by a user to the mobile terminal  100 . Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the mobile terminal  100  to recognize that it is correctly loaded in the cradle. 
     The controller  180  typically controls the overall operations of the mobile terminal  100 . For example, the controller  180  performs the control and processing associated with voice calls, data communications, video calls, etc. The controller  180  may include a multimedia module  181  that provides multimedia playback. The multimedia module  181  may be configured as part of the controller  180 , or implemented as a separate component. 
     Moreover, the controller  180  is able to perform a pattern (or image) recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images, respectively. 
     The power supply unit  190  provides power required by the various components for the mobile terminal  100 . The power may be internal power, external power, or combinations thereof.

     Referring to  FIG. 2B , a camera  121 ′ can be additionally provided to a backside of the terminal body, and more particularly, to the rear case  102 . The camera  121  has a photographing direction that is substantially opposite to that of the former camera  121  shown in  FIG. 21A  and may have pixels differing from those of the firmer camera  121 . 
     Preferably, for instance, the former camera  121  has low pixels enough to capture and transmit a picture of user&#39;s face for a video call, while the latter camera  121 ′ has high pixels for capturing a general subject for photography without transmitting the captured subject. And, each of the cameras  121  and  121 ′ can be installed at the terminal body to be rotated or popped up.

     In the following description, embodiments related to a controlling method implemented in the above-configured mobile terminal  100  are explained with reference to the accompanying drawings. 
     For clarity and convenience of the following description, assume that a mobile terminal  100  mentioned in the following description includes at least one of the components shown in  FIG. 1 . In particular, a mobile terminal  100  according to the present invention may include the user input unit  130 , the display unit  151 , the memory  160  and the controller  180 . In some cases, the mobile terminal  100  according to the present invention may further include the proximity sensor  141 . If the display module  151  includes a touchscreen  151 , implementation of the following embodiments may be further facilitated. Therefore, the following description is made on the assumption that the display module  151  includes the touchscreen  151 . Moreover, if the user input unit  130  includes the touch sensor  137 , the touchscreen  151  may be usable as the user input unit  130 . 
     According to the present invention, the mobile terminal  100  may become a sender terminal or a receiver terminal depending on a corresponding embodiment. 
     The mobile terminal according to one embodiment of the present invention preferably includes the camera  121 , the controller  180 , the display unit  151 , the memory  160 , the microphone  122 , the audio output module  152  and the like, by which the present invention may be non-limited. And, it is apparent to those skilled in the art that at least operation of the above-enumerated components can be omitted. 
     Modules configuring the mobile terminal  100  are described in association with embodiments of the present invention as follows. 
     First of all, the camera  121  acquires a first image in response to a shooting command and also acquires a plurality of second images in accordance with a preset condition. 
     The first image is acquired in response to a user&#39;s shooting command like the case that a user takes a photo using the camera  121  in general. 
     A plurality of the second images are acquired in accordance with a preset condition in case that a user intends to acquire the first image. For instance, a plurality of the second images are acquired periodically or aperiodically for a prescribed time ranging from a timing point of activating a program or application for the photographing to a timing point of receiving a shooting command, a prescribed time interval before/after receiving a shooting command from a timing point of activating a program or application for the photographing, or a prescribed time after receiving a shooting command, by which the present invention may be non-limited. Images acquired through the camera  121  in accordance with a preset condition are commonly called a second image. And, it is unnecessary for the second image to mean a photographed image of a same part of a same subject. 
     The memory  160  stores the acquired first image and a plurality of the acquired second images. In some cases, the memory  160  may play a role in temporarily storing the acquired first image and a plurality of the acquired second images until a synthetic image, which will be described later, is created. 
     The controller  180  creates a synthetic image based on the first image and a plurality of the second images. The controller  180  can select images, which will be used for creation of the synthetic image, from the first image and a plurality of the second images with reference to resolution. Since the first image acquired in response to a shooting command while a user focuses a camera lens for the purpose of taking a photo, the resolution of the first image may be higher than that of a plurality of the second images acquired in accordance with a preset condition. Hence, the controller  180  can create the synthetic image using the whole first image and at least one portion of a plurality of the second images. 
     The controller  180  controls the display unit  151  to display a prescribed visual effect for indicating a region corresponding to the first image in the synthetic image. 
     In case that at least two of a plurality of the second images include the same region, the controller  180  can create a synthetic image using an image having a highest resolution of the same region among the at least two images. In creating the synthetic image, a whole part of each of a plurality of the second images is usable or a partial region of the corresponding image may be usable depending on the resolution. For instance, the controller  180  can determine the resolution based on a contrast value. 
     Algorithm or program for the image synthesis may be saved in the memory  160 . 
     The display unit  151  displays the created synthetic image. In doing so, the synthetic image may be partially displayed on a screen of the display unit  151 . Alternatively, a portion or whole part of the synthetic image may be displayed on the screen of the display unit  151  in a manner of having its display magnification reduced. 
     The first image in the exact size acquired by the camera  121  may be included in the synthetic image. 
     On the contrary, each of a plurality of the second images used for the creation of the synthetic image may exist in the synthetic image in a manner of overlaying the second image adjacent to the corresponding second image in part at least. 
     The synthetic image includes a first region meeting a first condition and a second region meeting a second region. In this case, according to the first condition, a resolution is equal to or greater than a specific value. According to the second condition, a resolution is smaller than the specific value. Hence, the second region meeting the second condition is larger than the first region and includes the first region. The first region may correspond to the first image acquired by the camera  121 . In some cases, the synthetic image may further include a 3 rd  region that meets a 3 rd  condition. In this case, the resolution according to the 3 rd  condition is smaller than that according to the second condition. 
     The controller  180  can control the display unit  151  to display an indicator indicating the first region and an indicator indicating the second region on the synthetic image. In some cases, the controller  180  may control the display unit  151  to further display an indicator indicating the 3 rd  region on the synthetic image. For instance, the 3 rd  region may correspond to the whole synthetic image. 
     A first thumbnail image corresponding to the first region and a second thumbnail image corresponding to the second region can be displayed on the screen of the display unit  150 . In some cases, the display unit  151  may further display a 3 rd  thumbnail image corresponding to the 3 rd  region. If a first command for selecting the first thumbnail image is detected, the controller  180  controls the first region to be displayed on the display unit  151 . If a second command for selecting the second thumbnail image is detected, the controller  180  controls the second region to be displayed on the display unit  151 . If a 3 rd  command for selecting the 3 rd  thumbnail image is detected, the controller  180  can control the 3 rd  region to be displayed on the display unit  151 . 
     The controller  180  control electric audio data to be generated by receiving an external audio signal through the microphone  122  for a time ranging from a timing point of acquiring a first acquired image from the first image and a plurality of the second images to a timing point of acquiring a last acquired image from the first image and a plurality of the second images. In particular, the microphone  122  continuously receives the audio signal for the time ranging from the timing point of acquiring the first acquired image from the first image and a plurality of the second images to the timing point of acquiring the last acquired image from the first image and a plurality of the second images and then generates the electric audio data based on the received audio signal. 
     The memory  160  stores the generated audio data. The controller  180  controls each of the first image and a plurality of the second images to be saved in the memory  160  in a manner of being matched with a part of the audio data corresponding to the timing point of acquiring each of the first image and a plurality of the second images in the audio data. 
     The controller  180  can control the audio output module  152  to output the audio data in a preset interval from the part of the audio data corresponding to the first image acquired timing point in the whole audio data. 
     If a specific command is detected, the controller  180  can control the audio output module  152  to output a part of the audio data corresponding to images configuring the second region among the first image and a plurality of the second images. 
     For instance, assume that the images configuring the second region include the first image and two second images, that the two second images include a first subimage and a second subimage, respectively, that the first subimage is acquired by the camera  121  in the first place, and that the first image and the second subimage are then acquired by the camera  121  in order. On this assumption, if the specific command is detected, the controller  180  can control the audio output module  152  to output parts of the audio data ranging from an audio data part corresponding to a timing point of acquiring the first subimage to an audio data part corresponding to a timing point of acquiring the second subimage. In this case, the audio data parts corresponding to the images configuring the second region are taken as an example for this description. Moreover, since the above method can be similarly applied to a case of outputting audio data parts corresponding to images configuring the 3 rd  region or audio data parts corresponding to images configuring a prescribed region selected by a user, corresponding details shall be omitted from the following description. 
     In the following description, embodiments of the present invention are explained in detail with reference to the accompanying drawings. 
       FIG. 3  is a flowchart for a method of controlling a mobile terminal according to one embodiment of the present invention. 
     Referring to  FIG. 3 , the camera  121  of the mobile terminal  100  acquires a first image in response to a shooting command and a plurality of second images according to a preset condition [S 201 ]. According to an embodiment, the controller  180  can control electric audio data to be generated in a manner of receiving an external audio signal through the microphone  122  for a time ranging from a timing point of acquiring a first acquired image from the first image and a plurality of the second images to a timing point of acquiring a last acquired image from the first image and a plurality of the second images. 
     The memory  160  can store the acquired first image, a plurality of the acquired second images and the audio data. 
     The controller  180  of the mobile terminal  100  creates a synthetic image by synthesizing the whole first image and at least one portion of a plurality of the second images [S 202 ]. The memory  160  can store the created synthetic image. 
     The display unit  151  of the mobile terminal  100  displays the synthetic image [S 203 ]. In doing so, the synthetic image may be partially displayed on a screen of the display unit  151 . Alternatively, a portion or whole part of the synthetic image may be displayed on the screen of the display unit  151  in a manner of having its display magnification reduced. 
     In the following description, a synthetic image and a process for creating the synthetic image are explained in detail with reference to  FIGS. 4 to 6 . 
       FIG. 4  is a diagram for one example of a synthetic image created from a mobile terminal according to one embodiment of the present invention. 
       FIG. 4( a )  shows a first image acquired by the camera  121  in response to a shooting command.  FIG. 4( b )  shows one example of a synthetic image  400  created based on the first image  310  acquired by the camera  121  in response to the shooting command and a plurality of the second images acquired by the camera  122  in accordance with a preset condition. 
     In the synthetic image, a prescribed visual effect I 1  indicating a region  401  corresponding to the first image  310  is displayed. For example, referring to  FIG. 4( b ) , as the prescribed visual effect indicating the region  401  corresponding to the first image, a first indicator I 1  indicating an outline of the region  401  corresponding to the first image  310  is displayed on the synthetic image  400 . In doing so, the first image  310  can be included in the synthetic image  400  by maintaining the exact size acquired by the camera  121 . 
     In the synthetic image  400 , a region  402  except the region  401  corresponding to the first image  310  is created using at least one portion of a plurality of the second images acquired according to the preset condition. In the synthetic image  400 , the region  402  except the region  401  corresponding to the first image  310  may exist in a manner that at least two adjacent images among a plurality of the second images overlay each other in part at least. 
       FIG. 5  is a diagram for another example of a synthetic image created in a mobile terminal according to one embodiment of the present invention. 
     Referring to  FIG. 5 , a synthetic image  400  created based on the first image  310  acquired by the camera  121  in response to the shooting command and a plurality of the second images acquired by the camera  122  in accordance with a preset condition is shown. 
     The synthetic image  400  includes a first region  411  meeting a first condition, a second region  412  meeting a second region by including the first region  411 , and a 3 rd  region  413  meeting a 3 rd  condition by including the second region  412 . In this case, the first condition includes a condition having a resolution set equal to or greater than a specific value, the second condition includes a condition having a resolution set smaller than the specific value, and the 3 rd  condition may include a condition having a resolution set smaller than that of the second condition. For instance, the first region  411  may include the region corresponding to the first image  310  acquired by the camera  121  in response to the shooting command and the 3 rd  region  412  may include the region corresponding to the whole synthetic image  400 . 
     On the synthetic image  400 , a first indicator I 1  indicating the first region  411  and a second indicator I 2  indicating the second region  412  may be displayed. For instance, the first indicator I 1  may indicate an outline of the first region  411  and the second indicator I 2  may indicate an outline of the second region  412 . 
     Moreover, in the synthetic image  400 , indicators P 1  to P 3  indicating informations on the first to 3 rd  regions  411  to  413  may be displayed on the first to 3 rd  regions  411  to  413 , respectively. For instance, the indicators P 1  to P 3  may include texts, pictures, graphic images and the like, which indicate informations on the first to 3 rd  regions  411  to  413 , respectively. 
       FIG. 6  is a diagram to describe one example of a process for creating a synthetic image in a mobile terminal according to one embodiment of the present invention, by which the synthetic image creating process according to the present invention may be non-limited. 
       FIG. 6( a )  shows that a first image  310  and a plurality of second images  320  are arranged in a manner of overlaying each other to connect objects in the images to each other.  FIG. 6( b )  shows that the first image  310  and a plurality of the second images  320  are rearranged by determining the before-after relationship of adjacent images shown in  FIG. 6  ( a ). 
     Referring to  FIG. 6 , the controller  180  creates a synthetic image  400  based on the first image  310  and a plurality of the second images  320 . In particular, the controller  180  can select images to use for the creation of the synthetic image  400  from the first image  310  and a plurality of the second images  320  with reference to resolution. The controller  180  can create the synthetic image  400  by synthesizing at least one portion of the first image  310  and a plurality of the second images  320 . 
     In  FIG. 6 , for example of a plurality of the second images  320  to be used for the creation of the synthetic image  400 , a first subimage  321 , a second subimage  322 , a 3 rd  subimage  323  and a 4 th  subimage  324  are shown. 
     Since the resolution of the first image  310  acquired in response to a shooting command is generally greater than that of the second images  320 , referring to  FIG. 6( b ) , the following description is made on the assumption of the case of using the whole first image  310  for the creation of the synthetic image  400 , by which the present invention may be non-limited. 
     In case that at least two of a plurality of the second images  320  include the same region, the controller  180  creates the synthetic image  400  using an image having the highest resolution of the same region among the at least two images. When the synthetic image  400  is created, a whole part of each of a plurality of the second images  320  may be used or a partial region of the corresponding image may be usable depending on the resolution. 
     Referring to  FIG. 6( a ) , the controller  180  compares the resolutions of the region  331  in the first subimage  321  and the second subimage  322 , each of which includes the same region  331 . As a result of the comparison, if the resolution of the region  331  in the second subimage  322  is greater than that of the region  331  in the first subimage  321 , referring to  FIG. 6( b ) , the controller  180  creates the synthetic image  400  using the region  331  included in the second subimage  322 . 
     The controller  180  compares the resolutions of the region  332  in the second subimage  322  and the 4 th  subimage  324 , each of which includes the same region  332 . As a result of the comparison, if the resolution of the region  332  in the second subimage  322  is greater than that of the region  332  in the 4 th  subimage  324 , the controller  180  creates the synthetic image  400  using the region  332  included in the second subimage  322 . 
     The controller  180  compares the resolutions of the region  333  in the first subimage  321  and the 3 rd  subimage  323 , each of which includes the same region  333 . As a result of the comparison, if the resolution of the region  333  in the 3 rd  subimage  323  is greater than that of the region  333  in the first subimage  321 , the controller  180  creates the synthetic image  400  using the region  333  included in the 3 rd  subimage  323 . 
     And, the controller  180  compares the resolutions of the region  334  in the 3 rd  subimage  323  and the 4 th  subimage  324 , each of which includes the same region  334 . As a result of the comparison, if the resolution of the region  334  in the 3 rd  subimage  323  is greater than that of the region  334  in the 4 th  subimage  324 , the controller  180  creates the synthetic image  400  using the region  334  included in the 3 rd  subimage  323 . 
     In the following description, a synthetic image  400  displayed on the display unit  151  of the mobile terminal  100  is explained in detail with reference to  FIG. 7 . 
       FIG. 7  is a diagram for one example of a synthetic image displayed on a display unit of a mobile terminal according to one embodiment of the present invention. 
     Referring to  FIG. 7 , a synthetic image  400  is displayed on the display unit  150  of the mobile terminal  100 . Since the synthetic image  400  is created using a first image  310  and a plurality of second images  320 , it is difficult for the whole synthetic image  400  to be displayed on a screen of the display unit  150  unless a display magnification is changed. Hence, the synthetic image  400  may be partially displayed on the screen of the display unit  151 . Alternatively, a portion or whole part of the synthetic image may be displayed on the screen of the display unit  151  in a manner of having its display magnification reduced. 
     Referring to  FIG. 7( a ) , a user is able to change a part of the synthetic image  400  displayed on the screen of the display unit  150  by touching and dragging the screen of the display unit  150 . The controller  180  can control the display unit  150  to display the synthetic image  400  in a manner of moving the synthetic image  400  on the screen of the display unit  150  in response to a touch command. 
     Referring to  FIG. 7( b ) , a user is able to change the display magnification of the synthetic image  400  displayed on the screen of the display unit  150  by performing zoom-in or zoom-out on the screen while touching two random points within the screen of the display unit  150 . In response to the zoom-in or zoom-out command attributed to the touch, the controller  180  can control the display unit  150  to display the synthetic image  400  in a manner of changing the display magnification of the synthetic image  400  on the screen of the display unit  150 . 
     Meanwhile, according to the present invention, when the synthetic image  400  is displayed on the display unit  150  of the mobile terminal  100 , a user can be informed whether the synthetic image  400  exists in a region except the screen of the display unit  150 . This is described in detail with reference to  FIG. 8  as follows. 
       FIG. 8  is a diagram for another example of a synthetic image displayed on a display unit of a mobile terminal according to one embodiment of the present invention. 
     Referring to  FIG. 8 , a synthetic image  400  is displayed on the display unit  150  of the mobile terminal  100 . 
     Since the synthetic image  400  is created using a first image  310  and a plurality of second images  320 , it is difficult for the whole synthetic image  400  to be displayed on a screen of the display unit  150  unless a display magnification is changed. In this case, the controller  180  can control the display unit  150  to display an indicator A indicating whether a part of the synthetic image  400  not displayed on the screen of the display unit  150  exists. 
     Referring to  FIG. 8( a ) , an indicator A 1  indicating that a continuous image does not further exist can be displayed on a part having no synthetic image  400  failing to be displayed on the screen of the display unit  150 , i.e., on an outline part of the synthetic image  400  displayed on the screen of the display unit  150 . For instance, the indicator A 1  may be denoted by coloring the outline of the synthetic image  400  black, by which the present invention may be non-limited. 
     Referring to  FIG. 8( b ) , an indicator A 2  indicating that a continuous image exists can be displayed on a part having the synthetic image  400  failing to be displayed on the screen of the display unit  150 . For instance, the indicator A 2  may be denoted by blurring a boundary line having the continuous image exist outside the screen in a part of the synthetic image  400  displayed on the screen of the display unit  150 , by which the present invention may be non-limited.
