     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an electronic device. More particularly, the present invention relates to a method and apparatus for capturing and transmitting an image, in a state where a message transmission/reception history is displayed in an electronic device. 
     2. Description of the Related Art 
     Most of electronic devices such as recently launched smart phone, tablet Personal Computer (PC) and the like are equipped with cameras in order to capture an image. Particularly, as a camera function becomes increasingly important, various interfaces for interworking a camera application with other applications in the electronic device are being provided. For example, by interworking the camera application with a messenger application, the electronic device can capture an image through the camera application during messenger application execution and then transmit the captured image to at least one other electronic device through the messenger application. 
     In a case where the electronic device intends to capture and transmit an image during the execution of a general messenger application (e.g., Kakaotalk), the electronic device performs a process of, after converting a messenger application screen into a camera application screen, capturing an image of a subject through the camera application, and again converting the camera application screen into the messenger application screen to transmit the captured image. However, there is a shortcoming in that a user has to undergo a plurality of processes in order to capture and transmit the image during the execution of the messenger application as described above. Also, as the screen conversion from the messenger application screen to the camera application screen occurs as described above, the user suffers an inconvenience of, when a message is received while capturing the image, failing to determine the received message instantly. 
     According to this, there is a need to provide a method for capturing and transmitting an image without a trouble process during messenger application execution in an electronic device. 
     The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present invention.

     In the following description, an electronic device includes a mobile communication terminal with a camera, a smart phone, a tablet Personal Computer (PC), a digital camera, a laptop computer, a netbook computer, a computer and the like. 
       FIG. 1A  is a block diagram illustrating a construction of an electronic device according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 1A , the electronic device  100  includes a memory  110 , a processor  120 , an Input/Output (IO) unit  130 , a camera  140 , and a communication unit  150 . The memory  110  and the processor  120  can be composed of a plurality of memories  110  and a plurality of processors  120 , respectively. 
     The memory  110  includes a data storage unit  111 , an Operating System (OS) program  112 , an application program  113 , a Graphical User Interface (GUI) program  114 , a camera program  115 , a message program  116  and the like. Also, the program that is a software constituent element can be expressed as a set of instructions, so the program may be expressed as an instruction set. The program is also expressed as a module. 
     The memory  110  can store at least one or more programs including instructions performing an exemplary embodiment of the present invention. 
     The data storage unit  111  stores data generated during the execution of a function corresponding to the program stored in the memory  110 . The data storage unit  111  according to the present exemplary embodiment can store an image. At this time, the stored image includes at least one of an image captured through the camera  140 , a previously stored image, and an image received from at least one other electronic device or a server. Further, the data storage unit  111  can store a message transmission/reception history by electronic device. 
     The OS software  112  (for example, a built-in operating system such as WINDOWS, LINUX, Darwin, RTXC, UNIX, OS X, or VxWorks) includes various software constituent elements controlling general system operations. Control of the general system operations includes memory management and control, storage hardware (device) control and management, power control and management and the like. Further, the OS software  112  performs a function of making smooth communication between various hardware (devices) and software constituent elements (programs). 
     The application program  113  includes applications of a browser, an electronic mail (e-mail), a message, word processing, an address book, a widget, Digital Right Management (DRM), voice recognition, voice replication, a position determining function, a location-based service, a call and the like. 
     The graphical user interface program  114  includes at least one software constituent element providing a user interface using a graphic between a user and the electronic device  100 . That is, the graphical user interface program  114  includes at least one software constituent element for displaying user interface information on the I/O unit  130 . According to the present exemplary embodiment, the graphical user interface program  114  includes an instruction for displaying a message transmission/reception history with at least one other electronic device. At this time, the at least one other electronic device represents a conversation partner&#39;s electronic device transmitting/receiving a message, and the message transmission/reception history represents a transmission/reception history (e.g., transmission message content, message transmission time, reception message content, message reception time, conversation partner&#39;s confirmation or non-confirmation for a transmission message and the like) of a message transmitted/received between the user of the electronic device  100  and a conversation partner of at least one other electronic device. 
     Also, the graphical user interface program  114  includes an instruction for displaying a preview screen of the camera  140  within a screen in which a message transmission/reception history is displayed. At this time, the preview screen can be displayed in any region within the screen in which the message transmission/reception history is displayed or can be displayed within a talk balloon in which message content is displayed. Also, the graphical user interface program  114  includes an instruction for moving the preview screen from a current region to another region by the camera program  115 . That is, the preview screen is displayed in a lower right region within the screen in which the message transmission/reception history is displayed in the drawing illustrating exemplary embodiments of the present invention described below. But, according to user control, the preview screen can be moved even to any location within the screen in which the message transmission/reception history is displayed. 
     Also, if a multi touch on a preview screen is sensed by the camera program  115 , the graphical user interface program  114  can zoom in or out the preview screen according to the sensed multi touch and display the zoomed preview screen. Also, the graphical user interface program  114  can display the preview screen in a full screen region in which a message transmission/reception history is displayed. Here, in a case where the preview screen is displayed in the full screen region in which the message transmission/reception history is displayed, the preview screen can be displayed as a wallpaper screen of the message transmission/reception history. 
     Also, the graphical user interface program  114  can arrange the displayed preview screen in front of a message window, or arrange the displayed preview screen as the wallpaper in rear of the message window. 
     Further, the graphical user interface program  114  includes an instruction for displaying recently stored at least one image around the preview screen. For example, the graphical user interface program  114  can display the recently stored at least one image at a lower end of the preview screen. 
     The camera program  115  includes a camera related software constituent element enabling camera related processes and functions. In the present exemplary embodiment, if a camera execution menu is selected in a state in which a message transmission/reception history is displayed, the camera program  115  can execute the camera  140  to display a camera preview screen in any region of a screen in which a message transmission/reception history is displayed. For example, the camera program  115  includes an instruction for displaying the camera preview screen in any region within the screen in which the message transmission/reception history with at least one other electronic device is displayed as illustrated in  FIG. 6 , or displaying the camera preview screen within a talk balloon within the screen in which the message transmission/reception history with the at least one other electronic device is displayed as illustrated in  FIG. 7 . 
       FIG. 6  is a diagram illustrating an example of displaying a preview screen in any region of a screen in which a message transmission/reception history is displayed, to capture and transmit an image in an electronic device according to an exemplary embodiment of the present invention.  FIG. 7  is a diagram illustrating an example of displaying a preview screen within a talk balloon including a transmission message, to capture and transmit an image in an electronic device according to an exemplary embodiment of the present invention. 
     At this time, the camera preview screen can be arranged and displayed in front of a message window, or can be arranged and displayed as the wallpaper in rear of the message window. The arrangement of the camera preview screen can be set in a setting step, and can be changed according to user control. 
     Further, the camera program  115  can display recently stored at least one or more images around a region in which a camera preview screen is displayed. At this time, whether to display only the camera preview screen or whether to concurrently display the camera preview screen and the recently stored at least one or more images can be determined according to user control or can be previously determined in a setting step. 
     Further, the camera program  115  includes an instruction for recognizing that a multi touch on a preview screen region is sensed through the I/O unit  130 , and performing a function corresponding to the sensed multi touch. For example, if at least two or more drags making progress in different directions about the preview screen region are sensed, the camera program  115  can zoom in or out the preview screen region depending on progress lengths of the sensed drags and/or progress locations thereof. At this time, if the sensed drags make progress a preset threshold distance or more, the camera program  115  zooms in the preview screen region by as much as a size of a screen in which a message transmission/reception history is displayed, thereby being capable of displaying the preview screen like a wallpaper screen of the screen in which the message transmission/reception history is displayed as illustrated in  FIG. 9 . 
       FIG. 9  is a diagram illustrating an example of zooming in a preview screen region by as much as a size of a screen in which a message transmission/reception history is displayed in an electronic device according to an exemplary embodiment of the present invention. 
     For another example, if the sensed multi touch on the preview screen region is dragged so as to be getting closer to each other, the camera program  115  can zoom out the preview screen region depending on progress lengths of the sensed drags and/or progress locations thereof. Also, if at least two or more drags making progress in the same direction about the preview screen region are sensed, the camera program  115  can move the preview screen from a current region to another region according to the progress locations of the sensed drags to display the moved preview screen. 
     Further, if a touch on a camera preview screen is sensed, the camera program  115  captures an image of a subject. Particularly, in a case where the preview screen is zoomed in by as much as a full screen in which a message transmission/reception history is displayed, if a touch on a region in which the message transmission/reception history is not displayed is sensed among a region of the zoomed-in preview screen, the camera program  115  can capture the image of the subject. 
     If the image of the subject is captured due to the sensing of the touch on the preview screen, the camera program  115  converts the preview screen into a screen displaying a captured image. That is, the camera program  115  displays the captured image instead of the preview screen in the preview screen region. After the image is captured, if a cancel menu is selected by user control, the camera program  115  again converts the screen displaying the captured image into the preview screen. 
     Also, if a touch on a recently stored image displayed around a preview screen region is sensed, the camera program  115  displays the touch-sensed image instead of the preview screen in the preview screen region. After displaying of the touch-sensed image, if a cancel menu is selected by user control, the camera program  115  again converts a screen displaying the touch-sensed image into the preview screen. 
     Further, the camera program  115  includes an instruction for, if a gesture for a captured image is sensed, transmitting the captured image to at least one other electronic device. At this time, the gesture includes at least one of a drag, a multi touch double tap, and a tap of a predetermined period of time. For example, if the double tap is sensed for the captured image, the camera program  115  can transmit the captured image to at least one other electronic device associated with a message transmission/reception history that is being displayed at least on a screen. 
       FIG. 4  is a diagram illustrating an example of capturing and transmitting an image within a screen in which a message transmission/reception history is displayed in an electronic device according to an exemplary embodiment of the present invention. 
     For another example, as illustrated in  FIG. 4 , if a drag making progress from the inside of a captured image to the outside thereof is sensed, the camera program  115  can transmit the captured image to at least one other electronic device. Particularly, if a drag makes progress from the inside of the captured image to a direction in which a message received from at least one other electronic device has been displayed, the camera program  115  can transmit the captured image to the at least one other electronic device. 
     Further, the camera program  115  can split a screen region in which a message transmission/reception history is displayed into at least two regions and then, store or transmit a corresponding image according to which region among the split screen regions a drag sensed for a captured image makes progress to. For example, assuming that the camera program  115  splits a screen region into three regions, if a drag for a captured image is sensed only within a 1st screen region, the camera program  115  can store the captured image in the data storage unit  111  of the memory  110 , without transmitting the captured image to the at least one other electronic device. For another example, if it is sensed that the drag for the captured image makes progress from the 1st screen region to a 2nd screen region, the camera program  115  can store the captured image in the data storage unit  111  of the memory  100  while transmitting the captured image to the at least one other electronic device. For further example, if it is sensed that the drag for the captured image makes progress from the 1st screen region to a 3rd screen region, the camera program  115  can transmit the captured image to the at least one other electronic device, without storing the captured image in the data storage unit  111  of the memory  110 . 
     Also, if a gesture for a recently stored image is sensed, the camera program  115  can transmit a gesture-sensed image to at least one other electronic device. For example, if it is sensed that a drag makes progress from the inside of a recently stored image displayed around a preview screen region to the outside thereof, the camera program  115  can transmit the drag-sensed image to at least one other electronic device. At this time, if a touch on a specific image among recently stored images displayed around the preview screen region is sensed, the camera program  115  can display the touch-sensed specific image in the preview screen region and then, sense a separate drag for the displayed image to transmit the drag-sensed image to the at least one other electronic device. Also, if the drag for the specific image among the recently stored images displayed around the preview screen region is sensed, the camera program  115  can just transmit the drag-sensed specific image to the at least one other electronic device, without displaying the drag-sensed specific image in the preview screen region. 
     Also, the camera program  115  includes an instruction for displaying an icon for capturing mode conversion within a screen in which a message transmission/reception history is displayed and, if the icon is selected by user control, converting an image (or still picture) capturing mode into a video capturing mode or converting the video capturing mode into the image capturing mode. Also, the camera program  115  can sense a preset gesture to convert a capturing mode. For example, the camera program  115  can sense a double tap, a tap of a predetermined period of time, and a single touch or multi touch making progress in a preset shape to convert the capturing mode. 
     After converting the image capturing mode into the video capturing mode, if a tap of a predetermined period of time for a preview screen is sensed, the camera program  115  can capture a video for a time during which the tap is sensed. For example, if a tap of one minute for the preview screen is sensed in the video capturing mode, the camera program  115  can capture a video for one minute. 
     The message program  116  can control the communication unit  150  for the sake of message transmission/reception with at least one other electronic device. 
     The processor  120  can be, although not illustrated, composed of at least one processor and peripheral interface. Also, the processor  120  executes a specific program (i.e., an instruction set) stored in the memory  110  to perform a plurality of specific functions corresponding to the executed program. 
     The I/O unit  130 , which is a touch-sensitive display, provides an interface for touch input/output between the electronic device  100  and a user. The I/O unit  130  is a medium for sensing a touch (or a contact) through a touch sensor (not shown), forwarding a sensed touch input to the electronic device  100 , and visually providing an output of the electronic device  100  to the user. That is, the I/O unit  130  provides a visual output based on a text, a graphic, and a video to the user, in response to the touch input. 
     The I/O unit  130  includes a touch sense surface sensing a user&#39;s touch input, to sense a user&#39;s touch input of a haptic contact scheme, a tactile contact scheme or a combination scheme of them. For example, a touch sense point of the I/O unit  130  corresponds to a digit that is used for contact to the touch sense surface. Also, the I/O unit  130  senses a contact of an external device such as a stylus pen and the like through the touch sense surface. The detected contact is transformed into interaction corresponding to a user interface object (e.g., a soft key) displayed on the I/O unit  130 . 
     The I/O unit  130  provides an interface for touch input/output between the electronic device  100  and a user. In detail, the I/O unit  130  is a medium for forwarding a user&#39;s touch input to the electronic device  100 , and visually providing an output of the electronic device  100  to the user. The I/O unit  130  can use various display technologies such as a Liquid Crystal Display (LCD), a Light Emitting Diode (LED), a Light emitting Polymer Display (LPD), an Organic Light Emitting Diode (OLED), an Active Matrix Organic Light Emitting Diode (AMOLED), or a Flexible LED (FLED). The I/O unit  130  of the present exemplary embodiment is not limited to a touch screen using these display technologies. Also, the I/O unit  130  can sense a start of a contact to a touch sense surface, a movement of the contact, or an interruption or termination of the contact, by using various touch detection (or sensing) technologies such as capacitive detection, resistive detection, infrared detection and surface acoustic wave detection technologies. The I/O unit  130  according to the present exemplary embodiment can display a message transmission/reception history and can display a camera preview screen in any region of a screen in which the message transmission/reception history is displayed. Further, the I/O unit  130  can sense a gesture for the displayed preview screen. At this time, the gesture includes at least one of a tap, a double tap, a drag, and a tap of a predetermined period of time. 
     The camera  140  can capture an image of a subject according to user control. Particularly, if a camera execution menu is selected in a state where a message transmission/reception history is displayed, the camera  140  according to the present exemplary embodiment can be executed to capture an image of the subject. Further, in a video capturing mode, the camera  140  can capture a video during a time during which a touch is sensed for a preview screen by control of the camera program  115 . At this time, the camera  140  can be provided at least one surface among a front surface of the electronic device  100  and a rear surface thereof. In a case where the camera  140  is provided at all of the front surface and the rear surface, the rear surface camera  140  is executed as default. At this time, the executed camera among the front and rear surface cameras can be changed according to user control, and can be previously determined in a setting step. 
     The communication unit  150  can include a radio frequency receiver and transceiver and/or an optical (e.g., infrared) receiver and transceiver. For example, the communication unit  150  can include a wireless communication system supporting any one of a Global System for Mobile Communication (GSM) network, an Enhanced Data GSM Environment (EDGE) network, a Code Division Multiple Access (CDMA) network, a Wireless-Code Division Multiple Access (W-CDMA) network, a Long Term Evolution (LTE) network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, a Wireless Fidelity (Wi-Fi) network, Near Field Communication (NFC), Infrared Data Association (IrDA), a Wireless interoperability for Microwave Access (WiMAX) network or/and a Bluetooth network. A wireless communication system according to an exemplary embodiment of the present invention is not limited to the wireless communication system supporting the aforementioned networks, and may be a wireless communication system supporting other networks. The communication unit  150  according to the present exemplary embodiment can transmit an image and a video to at least one other electronic device by the camera program  115 . Further, the communication unit  150  according to the present exemplary embodiment can receive an image and a video from at least one other electronic device. Also, the communication unit  150  can transmit/receive a message with at least one other electronic device. 
       FIG. 1B  illustrates a construction of a processor of an electronic device according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 1B , the processor  120  includes a camera processor  122  and a message control processor  124 . According to this, the processor  120  directly performs functions of the camera program  115  and the message program  116  in  FIG. 1A . 
     That is, the camera processor  122  includes a camera related software constituent element enabling camera related processes and functions. In the present exemplary embodiment, if a camera execution menu is selected in a state in which a message transmission/reception history is displayed, the camera processor  122  can execute the camera  140  to display a camera preview screen in any region of a screen in which a message transmission/reception history is displayed. For example, the camera processor  122  performs a function for displaying the camera preview screen in any region within the screen in which the message transmission/reception history with at least one other electronic device is displayed as illustrated in  FIG. 6 , or displaying the camera preview screen within a talk balloon within the screen in which the message transmission/reception history with the at least one other electronic device is displayed as illustrated in  FIG. 7 . At this time, the camera preview screen can be arranged and displayed in front of a message window, or can be arranged and displayed as the wallpaper in rear of the message window. The arrangement of the camera preview screen can be set in a setting step, and can be changed according to user control. 
     Further, the camera processor  122  can display recently stored at least one or more images around a region in which a camera preview screen is displayed. At this time, whether to display only the camera preview screen or whether to concurrently display the camera preview screen and the recently stored at least one or more images can be determined according to user control or can be previously determined in a setting step. 
     Further, the camera processor  122  performs a control function for recognizing that a multi touch on a preview screen region is sensed through the I/O unit  130 , and performing a function corresponding to the sensed multi touch. For example, if at least two or more drags making progress in different directions about the preview screen region are sensed, the camera processor  122  can zoom in or out the preview screen region depending on progress lengths of the sensed drags and/or progress locations thereof. At this time, if the sensed drags make progress a preset threshold distance or more, the camera processor  122  zooms in the preview screen region by as much as a size of a screen in which a message transmission/reception history is displayed, thereby being capable of displaying the preview screen like a wallpaper screen of the screen in which the message transmission/reception history is displayed as illustrated in  FIG. 9 . For another example, if the sensed multi touch on the preview screen region is dragged so as to be getting closer to each other, the camera processor  122  can zoom out the preview screen region depending on progress lengths of the sensed drags and/or progress locations thereof. Also, if at least two or more drags making progress in the same direction about the preview screen region are sensed, the camera processor  122  can move the preview screen from a current region to another region according to the progress locations of the sensed drags to display the moved preview screen. 
     Further, if a touch on a camera preview screen is sensed, the camera processor  122  captures an image of a subject. Particularly, in a case where the preview screen is zoomed in by as much as a full screen in which a message transmission/reception history is displayed, if a touch on a region in which the message transmission/reception history is not displayed is sensed among a region of the zoomed-in preview screen, the camera processor  122  can capture an image of the subject. 
     If the image of the subject is captured due to the sensing of the touch on the preview screen, the camera processor  122  converts the preview screen into a captured image display screen. That is, the camera processor  122  displays a captured image instead of the preview screen in the preview screen region. After the image is captured, if a cancel menu is selected by user control, the camera processor  122  again converts the captured image display screen into the preview screen. 
     Also, if a touch on a recently stored image displayed around a preview screen region is sensed, the camera processor  122  displays the touch-sensed image instead of the preview screen in the preview screen region. After displaying of the touch-sensed image, if a cancel menu is selected by user control, the camera processor  122  again converts a screen displaying the touch-sensed image into the preview screen. 
     Further, the camera processor  122  performs a control function for, if a gesture for a captured image is sensed, transmitting the captured image to at least one other electronic device. At this time, the gesture includes at least one of a drag, a multi touch double tap, and a tap of a predetermined period of time. For example, if the double tap is sensed for the captured image, the camera processor  122  can transmit the captured image to at least one other electronic device associated with a message transmission/reception history that is being displayed at least on a screen. For another example, as illustrated in  FIG. 4 , if a drag making progress from the inside of a captured image to the outside thereof is sensed, the camera processor  122  can transmit the captured image to at least one other electronic device. Particularly, if a drag makes progress from the inside of the captured image to a direction in which a message received from at least one other electronic device has been displayed, the camera processor  122  can transmit the captured image to the at least one other electronic device. 
     Further, the camera processor  122  can split a screen region in which a message transmission/reception history is displayed into at least two regions and then, store or transmit a corresponding image according to which region among the split screen regions a drag sensed for a captured image makes progress to. For example, assuming that the camera processor  122  splits a screen region into three regions, if a drag for a captured image is sensed only within a 1st screen region, the camera processor  122  can store the captured image in the data storage unit  111  of the memory  110 , without transmitting the captured image to at least one other electronic device. For another example, if it is sensed that the drag for the captured image makes progress from the 1st screen region to a 2nd screen region, the camera processor  122  can store the captured image in the data storage unit  111  of the memory  100  while transmitting the captured image to the at least one other electronic device. For a further example, if it is sensed that the drag for the captured image makes progress from the 1st screen region to a 3rd screen region, the camera processor  122  can transmit the captured image to at least one other electronic device, without storing the captured image in the data storage unit  111  of the memory  110 . 
     Also, if a gesture for a recently stored image is sensed, the camera processor  122  can transmit a gesture-sensed image to at least one other electronic device. For example, if it is sensed that a drag makes progress from the inside of a recently stored image displayed around a preview screen region to the outside thereof, the camera processor  122  can transmit the drag-sensed image to at least one other electronic device. At this time, if a touch on a specific image among recently stored images displayed around the preview screen region is sensed, the camera processor  122  can display the touch-sensed specific image in the preview screen region and then, sense a separate drag for the displayed image to transmit the drag-sensed image to the at least one other electronic device. Also, if the drag for the specific image among the recently stored images displayed around the preview screen region is sensed, the camera processor  122  can transmit the drag-sensed specific image to the at least one other electronic device, without displaying the drag-sensed specific image in the preview screen region. 
     Also, the camera processor  122  performs a function for displaying an icon for capturing mode conversion within a screen in which a message transmission/reception history is displayed and, if the icon is selected by user control, converting an image (or still picture) capturing mode into a video capturing mode or converting the video capturing mode into the image capturing mode. Also, the camera processor  122  can sense a preset gesture to convert a capturing mode. For example, the camera processor  122  can sense a double tap, a tap of a predetermined period of time, and a single touch or multi touch making progress in a preset shape to convert the capturing mode. 
     After converting the image capturing mode into the video capturing mode, if a tap of a predetermined period of time for a preview screen is sensed, the camera processor  122  can capture a video for a time during which the tap is sensed. For example, if a tap of one minute for the preview screen is sensed in the video capturing mode, the camera processor  122  can capture a video for one minute. 
     The message processor  124  can control the communication unit  150  for the sake of message transmission/reception with at least one other electronic device. 
       FIG. 2A  illustrates a procedure of transmitting a captured image to at least one other electronic device in an electronic device according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 2A , in step  201 , the electronic device  100  displays a message transmission/reception history with at least one other electronic device. At this time, the message transmission/reception history represents a transmission/reception history of a message transmitted/received between the user of the electronic device  100  and a conversation partner of at least one other electronic device. 
     After that, the electronic device  100  proceeds to step  203  and senses a selection of a camera execution menu. At this time, the electronic device  100  can display a menu (e.g., a camera icon) for camera execution within a screen in which the message transmission/reception history is displayed. 
     In step  205 , the electronic device  100  can display a camera preview screen within the screen in which the message transmission/reception history is displayed. At this time, the electronic device  100  can display the camera preview screen in any region within the screen in which the message transmission/reception history is displayed, or display the camera preview screen within a talk balloon including a transmission message. 
     Next, the electronic device  100  proceeds to step  207  and can capture an image of a subject if a touch on the preview screen is sensed. At this time, the electronic device  100  can display a captured image in a preview screen region. Further, in a video capturing mode, the electronic device  100  can capture a video for a time during which the preview screen is touched. 
     After that, the electronic device  100  proceeds to step  209  and transmits the captured image to the at least one other electronic device if a gesture for the captured image is detected. At this time, the gesture includes at least one of a double tap, a drag, and a tap of a predetermined period of time. For example, if the double tap for the captured image is sensed, the electronic device  100  can transmit the captured image to the at least one other electronic device. For another example, if a drag making progress from the inside of the captured image to the outside thereof is sensed, the electronic device  100  can transmit the captured image to the at least one other electronic device. At this time, the outside of the captured image means a direction in which a message received from the at least one other electronic device is displayed within the screen in which the message transmission/reception history is displayed. 
       FIG. 2B  illustrates a means for transmitting a captured image to at least one other electronic device in an electronic device according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 2B , the electronic device  100  includes a means  211  for displaying a message transmission/reception history with at least one other electronic device, and a means  213  for sensing a selection of a camera execution menu. At this time, the camera  140  can be provided in at least one surface among a front surface of the electronic device  100  and a rear surface thereof. If the camera  140  is provided in all of the front surface and the rear surface, the electronic device  100  basically executes a rear surface camera  140 . The electronic device  100  can include a means for changing the executed camera  140  according user control. 
     Further, the electronic device  100  includes a means  215  for displaying a camera preview screen within a screen in which a message transmission/reception history is displayed. 
     Also, the electronic device  100  includes a means  217  for, if a touch on a preview screen is sensed, capturing an image of a subject, and includes a means  219  for, if a gesture for a captured image is detected, transmitting the captured image to at least one other electronic device. At this time, the gesture includes at least one of a double tap, a drag, and a tap of a predetermined period of time. The electronic device  100  includes a means for detecting the gesture. 
       FIG. 3  illustrates a procedure of capturing and transmitting an image within a screen in which a message transmission/reception history is displayed in an electronic device according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 3 , the electronic device  100  executes a messenger application in step  301  and then, proceeds to step  303  and displays a message transmission/reception history. At this time, the message transmission/reception history represents a transmission/reception history of a message transmitted/received between a user of the electronic device  100  and a conversation partner of at least one other electronic device. For example, the message transmission/reception history includes at least one of transmission message content, message transmission time, reception message content, message reception time, conversation partner&#39;s confirmation or non-confirmation for a transmission message and the like. 
     After that, in step  305 , the electronic device senses a selection of a camera execution menu (e.g., a camera icon). In other words, the electronic device  100  can sense the selection of the camera execution menu displayed within the screen in which the message transmission/reception history is displayed. 
     Next, the electronic device  100  proceeds to step  307  and displays a camera preview screen and a recently stored image. At this time, the preview screen can be displayed in any region within the screen in which the message transmission/reception history is displayed or can be displayed within a talk balloon in which message content is displayed. For example, the electronic device  100  can display a preview screen in a lower right region within the screen in which the message transmission/reception history is displayed as illustrated in  FIGS. 4 to 6 . 
     For another example, the electronic device  100  can display a preview screen within a talk balloon including a transmission message within the screen in which the message transmission/reception history is displayed as illustrated in  FIG. 7 . Also, the recently stored at least one image can be displayed in any region within the screen in which the message transmission/reception history is displayed or in a region around the preview screen. For example, the electronic device  100  can display recently stored three images among images stored in the data storage unit  111 , at a lower end of the preview screen as illustrated in  FIG. 8 . 
       FIG. 8  is a diagram illustrating an example of displaying a recently stored image around a preview screen to transmit the displayed image in an electronic device according to an exemplary embodiment of the present invention. 
       FIG. 5  is a diagram illustrating an example of adjusting a size of a preview screen and a location thereof in an electronic device according to an exemplary embodiment of the present invention. 
     At this time, as illustrated in  FIG. 5 , if a multi touch on the preview screen is sensed, the electronic device  100  can adjust a size of the preview screen and a location thereof according to the sensed multi touch. For example, if the multi touch sensed for the preview screen region is dragged to as to be getting distant from each other, the electronic device  100  can zoom in a preview screen region depending on progress lengths of the sensed drags and progress locations thereof. Particularly, if the drags sensed for the preview screen region make progress a preset threshold distance or more, the electronic device  100  zooms in the preview screen region by as much as a size of a screen in which a message transmission/reception history is displayed, thereby being capable of obtaining the same effect as the preview screen is a wallpaper screen of the screen in which the message transmission/reception history is displayed as illustrated in  FIG. 9 . For another example, if the sensed multi touch on the preview screen region is dragged to as to be getting closer to each other, the electronic device  100  can zoom out an image displayed in the preview screen region depending on progress lengths of the sensed drags and/or progress locations thereof. For further example, if at least two or more drags making progress in the same direction about the preview screen region are sensed, the electronic device  100  can move the preview screen according to locations of the sensed drags. 
     After that, the electronic device  100  proceeds to step  309  and determines whether a touch on a preview screen is sensed or whether a touch on a stored image is sensed. 
     If the touch on the preview screen is sensed in step  309 , the electronic device  100  proceeds to step  311  and captures an image of a subject. At this time, after capturing the subject, the electronic device  100  can convert the preview screen into a screen displaying a captured image. That is, the electronic device  100  can display the captured image instead of the preview screen in a region in which the preview screen is displayed. Here, if the preview screen region is zoomed in by as much as a size of the screen in which the message transmission/reception history is displayed according to user control, the electronic device  100  can capture the image of the subject, when a touch is sensed on a region in which the message transmission/reception history is not displayed. Further, if a current capturing mode is a video capturing mode, after sensing a touch of a predetermined period of time on the preview screen, the electronic device  100  can capture a video while the sensed touch is maintained. 
     Next, the electronic device  100  proceeds to step  313  and determines if a gesture for the captured image is sensed. At this time, the gesture includes at least one of a double tap, a drag, and a tap of a predetermined period of time. Here, the captured image is a meaning including the captured video. 
     If it is determined in step  313  that the gesture for the captured image is not sensed, the electronic device  100  senses a selection of a cancel menu in step  315  and then, returns to step  307  and again performs the subsequent steps. 
     On contrary, if it is determined in step  313  that the gesture for the captured image is sensed, the electronic device  100  proceeds to step  317  and transmits the captured image to at least one other electronic device and then, terminates the procedure according to the present exemplary embodiment. For example, as illustrated in  FIG. 6 , the electronic device  100  can sense a drag for a captured image displayed in the preview screen region, to transmit the captured image to at least one other electronic device. For another example, as illustrated in  FIG. 7 , the electronic device  100  can sense a drag for a captured image displayed in the preview screen region within a talk balloon including a transmission message, to transmit the captured image displayed in the preview screen region to at least one other electronic device. 
     At this time, the electronic device  100  can split a screen region in which a message transmission/reception history is displayed into at least two regions and then, store and transmit a corresponding image depending on which screen region among the split screen regions a drag sensed for an image makes progress to. 
       FIG. 10  is a diagram illustrating an example of storing and transmitting an image depending on a progress region of a drag of the image in an electronic device according to an exemplary embodiment of the present invention. 
     For example, as illustrated in  FIG. 10 , the electronic device  100  can split a screen region in which a message transmission/reception history is displayed into regions ‘A’, ‘B’, and ‘C’ and then, store and transmit a corresponding image depending on which region among the regions ‘A’, ‘B’, and ‘C’ the drag sensed for the image makes progress to. At this time, if a drag sensed for a captured image makes progress only within the region ‘C’, the electronic device  100  can store the captured image in the memory  100  and, if the drag sensed for the captured image starts from the region ‘C’ and makes progress to the region ‘B’, the electronic device  100  can store the captured image in the memory  110  and concurrently transmit the captured image to at least one other electronic device. Also, if the drag sensed for the captured image starts from the region ‘C’ and makes progress to the region ‘A’, the electronic device  100  can transmit the captured image to at least one other electronic device without storing the captured image in the memory  110 . 
       FIG. 11  is a diagram illustrating an example of storing and transmitting a video depending on a progress region of a drag of the video in an electronic device according to an exemplary embodiment of the present invention. 
     For another example, as illustrated in  FIG. 11 , the electronic device  100  can split a screen region in which a message transmission/reception history is displayed into regions ‘A’ and ‘B’ and then, store and transmit a captured video depending on which region among the regions ‘A’ and ‘B’ the drag sensed for the captured video makes progress to. If a drag sensed for a captured video makes progress only within the region ‘B’, the electronic device  100  can store the captured video in the memory  100  and, if the drag sensed for the captured video starts from the region ‘B’ and makes progress to the region ‘A’, the electronic device  100  can store the captured video in the memory  110  and concurrently transmit the captured video to at least one other electronic device. 
     Also, in a state where an image is captured after a preview screen region is zoomed in by as much as a size of a screen in which a message transmission/reception history is displayed, the electronic device  100  can sense a touch on a region in which the message transmission/reception history is not displayed, and store and transmit the captured image depending on which screen region the sensed touch is dragged to. 
       FIG. 12  is a diagram illustrating an example of storing and transmitting a zoomed-in image depending on a progress region of a drag of the zoomed-in image in an electronic device according to an exemplary embodiment of the present invention. 
     For example, as illustrated in  FIG. 12 , the electronic device  100  can split a screen region in which a message transmission/reception history is displayed into regions ‘A’, ‘B’, and ‘C’ and then, store and transmit a captured image depending on which region among the regions ‘A’, ‘B’, and ‘C’ a touch generated in a region in which a message transmission/reception history is not displayed is dragged to. If the touch for the region in which the message transmission/reception history is not displayed is dragged only within the region ‘C’, the electronic device  100  can store the captured image in the memory  100 . For another example, if the touch for the region in which the message transmission/reception history is not displayed is sensed within the region ‘C’ and is dragged to the region ‘B’, the electronic device  100  can store the captured image in the memory  110  while transmitting the captured image to at least one other electronic device. For further example, if the touch for the region in which the message transmission/reception history is not displayed is sensed within the region ‘C’ and is dragged to the region ‘A’, the electronic device  100  can transmit the captured image to at least one other electronic device without storing the captured image in the memory  110 . 
     If the touch on the stored image is sensed in step  309 , the electronic device  100  proceeds to step  319  and substitutes and displays the touch-sensed image in the preview screen region. In detail, if a touch on a specific image among images displayed around the preview screen is sensed, the electronic device  100  can display the touch-sensed specific image in the preview screen region. At this time, if the preview screen region is greater than a recently stored image display region, the touch-sensed specific image can be zoomed in and displayed according to a size of the preview screen region. 
     Next, the electronic device  100  proceeds to step  321  and determines if a gesture for the substituted and displayed image is sensed. At this time, the gesture includes at least one of a double tap, a drag, and a tap of a predetermined period of time, and can be the same gesture as the gesture for transmitting the captured image. 
     If it is determined in step  321  that the gesture for the substituted and displayed image is not sensed, the electronic device senses a selection of a cancel menu in step  323  and then, returns to step  307  and again performs the subsequent steps. 
     On contrary, if it is determined in step  321  that the gesture for the substituted and displayed image is sensed, the electronic device  100  proceeds to step  325  and transmits the substituted and displayed image to at least one other electronic device and then, terminates the procedure according to the present exemplary embodiment. At this time, if a gesture for image transmission is sensed for an image displayed around the preview screen as illustrated in  FIG. 8 , the electronic device  100  can transmit the gesture-sensed image to at least one other electronic device without a process of substituting and displaying the gesture-sensed image in the preview screen region.
