The user input unit 130 generates input data for the user to control the operation of the terminal. The user input unit 130 may include a key pad dome switch, a touch pad (static pressure / capacitance), a jog wheel, a jog switch, and the like. In particular, when the touch pad has a mutual layer structure with the display unit 151 described later, this may be referred to as a touch screen.

The sensing unit 140 detects a current state of the mobile terminal 100 such as an open / closed state of the mobile terminal 100, a location of the mobile terminal 100, presence or absence of a user contact, orientation of the mobile terminal, acceleration / deceleration of the mobile terminal, and the like. To generate a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it may sense whether the slide phone is opened or closed. In addition, it is responsible for sensing functions related to whether the power supply unit 190 is supplied with power or whether the interface unit 170 is coupled to an external device.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, wired / wireless headset ports, external charger ports, wired / wireless data ports, memory card ports, ports for connecting devices with identification modules, audio input / output (I / O) ports, Video I / O (Input / Output) port, earphone port, etc. may be included.

Here, the identification module is a chip that stores various types of information for authenticating the use authority of the mobile terminal 100, and includes a user identification module (UIM) and a subscriber identify module (SIM). ), A Universal Subscriber Identity Module (“USIM”), and the like. In addition, the device equipped with the identification module (hereinafter referred to as 'identification device'), may be manufactured in the form of a smart card (smart card).

When the mobile terminal 100 is in a video call mode or a photographing mode, the mobile terminal 100 displays a photographed and / or received image, a UI, or a GUI.

Meanwhile, as described above, when the display unit 13 and the touch pad form a mutual layer structure to form a touch screen, the display unit 151 may be used as an input device in addition to the output device. The display unit 151 may include a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and a three-dimensional display. 3D display). In addition, two or more display units 151 may exist according to an implementation form of the mobile terminal 100. For example, an external display unit (not shown) and an internal display unit (not shown) may be simultaneously provided in the mobile terminal 100. The touch screen may be configured to detect not only the touch input position and the touched area but also the touch input pressure. In addition, the touch screen may be configured to detect not only the real-touch but also proximity touch.

In the present specification, the term "real-touch" refers to a case in which a pointer is actually touched on the screen, and the term "proximity-touch" refers to a point in which the pointer actually touches the screen. Instead, it refers to the case where the screen approaches a distance from the screen. In the present specification, a pointer refers to a tool for touching or proximity touching a specific portion of a displayed screen. Examples include stylus fans, fingers, and the like.

Although not shown in the drawing, various sensors may be provided inside or near the touch screen to detect a touch or a proximity touch of the touch screen. Alternatively, various sensors for detecting the touch or the proximity touch of the touch screen may be disposed in the sensing unit 140.

An example of a sensor for sensing a touch of the touch screen is a tactile sensor.

The tactile sensor refers to a sensor that senses the contact of a specific object to the extent that a person feels or more. The tactile sensor may sense various information such as the roughness of the contact surface, the rigidity of the contact object, the temperature of the contact point, and the like.

In addition, a sensor for detecting a touch of the touch screen may detect a touch drag. "Touch drag" refers to a case where a touched point is moved while the touch is maintained. That is, it is a case of dragging while the touch is maintained. Tapping a predetermined point on the display screen with a pointer to distinguish it from touch drag may be referred to as a "tap-touch". In this case, a sensor (eg, a tactile sensor) that detects a touch may sense a drag direction, a drag speed, a drag length, and the like of the touch drag.

An example of a sensor for sensing a touch of the touch screen is a proximity sensor.

The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. Thus, proximity sensors have a considerably longer life than contact sensors and their utilization is also quite high.

Examples of the proximity sensor include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

To explain an example of the operation principle of the high frequency oscillation type proximity sensor, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface in the state of oscillating the high frequency wave of the wave in the oscillation circuit. This change is converted into an electrical signal to detect the presence or absence of a sensing object. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even when the proximity sensor is not firmly mounted, when the touch screen is capacitive, the proximity sensor may be configured to detect the proximity of the pointer by a change in an electric field according to the proximity of the pointer. Therefore, when the pointer is located in close proximity to the touch screen although it is not actually touched, the position of the pointer and the distance between the pointer and the touch screen may be detected.

In addition, the position of the proximity touch with the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in proximity touch. If the proximity sensor is within a predetermined distance range, the proximity sensor may recognize it as a proximity touch. Proximity means the distance away from the screen and the pointer. In particular, the proximity distance may mean the shortest distance away from the screen and the pointer.

In addition, in the present specification, the term "predetermined touch of the screen" means that the pointer is located at a position on the space vertically corresponding to the predetermined point, and is recognized as a proximity touch.

The proximity sensor detects a proximity touch and a proximity touch pattern (eg, proximity distance, proximity touch direction, proximity speed, proximity touch time, proximity touch position, proximity touch movement state, etc.), and detects the detected proximity. Information corresponding to the touch operation and the proximity touch pattern may be output on the touch screen. In this specification, the proximity speed means a speed at which the pointer approaches the screen or a speed at which the pointer moves away from the screen. For example, the proximity sensor may detect the drag direction, drag speed, drag length, and the like of the proximity drag. The term "proximity-drag" refers to a case where the proximity touched point is moved while the proximity touch is maintained. That is, the case where the drag is performed while the proximity touch is maintained.

The sound output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. In addition, the sound output module 152 outputs a sound signal related to a function (eg, a call signal reception sound, a message reception sound, etc.) performed in the mobile terminal 100. The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying occurrence of an event of the mobile terminal 100. Examples of events occurring in the mobile terminal include call signal reception, message reception, and key signal input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, the alarm unit 153 may output a vibration in response to the key signal input. Through the vibration output as described above, the user can recognize the occurrence of the event. Of course, the signal for event occurrence notification may be output through the display unit 151 or the voice output module 152.

The memory 160 may store a program for processing and controlling the controller 180 and may provide a function for temporarily storing input / output data (for example, a phone book, a message, a still image, a video, etc.). It can also be done.

For example, perform related control and processing for voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for playing multimedia. The multimedia module 181 may be implemented in the controller 180 or may be implemented separately from the controller 180.

The power supply unit 190 receives an external power source and an internal power source under the control of the controller 180 to supply power for operation of each component.

The camera 121 of the second body 205 has a photographing direction substantially opposite to the camera 121 of the first body 200, and the camera 121 and the camera 121 of the first body 200. And may have different pixels.

For example, the camera 121 of the first body 200 has a low pixel so that it is easy to take a picture of the user's face and transmit it to the counterpart in the case of a video call, and the camera 121 of the second body has a general structure. It is desirable to have a high pixel because the subject is often photographed and not immediately transmitted.

The flash 250 and the mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 illuminates the subject when the subject is photographed by the camera 121 of the second body 205.

The user may transmit his / her own image taken using the camera 121 of the mobile terminal 100 to the other party, and receive the other party's image to perform a video call (S10). The image transmission and the counterpart image reception of the user may be performed through the wireless communication unit 110. The transmitted user's image and the received counterpart's image are displayed on the display unit 151. In this case, the user may transmit a substitute image instead of the image photographed through the camera 121 (S20). In this case, the substitute image may include at least one of a still picture and a moving picture.

When a key signal for transmitting an alternate video is input, the controller 180 determines whether a video call counterpart ID is stored (S30). In the present specification, the ID refers to information for identifying a specific person, and may include a name, nickname, and ID on the Internet.

When the ID of the call counterpart is stored, the controller 180 may search for the ID of the call counterpart in the storage space of the mobile terminal 100 (S40). Here, the storage space refers to a space where data is stored and may be a memory 160.

The controller 180 can extract an image related to the call counterpart ID using the searched ID (S50).

When the video associated with the ID of the video call counterpart is extracted, the controller 180 may transmit only the extracted video to the counterpart (S60, S80), or may include and transmit specific additional information in the extracted video (S60, S70). The additional information may include temporal information, spatial and the like of the transmitted image.

"Temporal information" is information indicating a temporal relationship between each transmitted image or a temporal relationship between the transmitted image and the image, and information on the duration of time that the image is displayed (for convenience, referred to as duration information), Information indicating a time interval between the displayed image and the image (for convenience, referred to as interval information). "Spatial information" refers to information for laying out in a specific space of an image. The display information may be provided using the additional information.

In addition, the controller 180 may automatically transmit all of the extracted images, or may transmit only the image selected by the user among the extracted images.

In addition, only one extracted image may be transmitted or a plurality of images may be transmitted. In particular, when a plurality of images are transmitted, the images may be transmitted at predetermined time intervals. For example, if there are five images to be transmitted, five images may be repeatedly transmitted at three second intervals.

Meanwhile, when the ID of the video call counterpart is not stored, the controller 180 can display the stored image. In this case, the user may select an image to be transmitted as a substitute image among the displayed stored images (S90). In this case, one image may be selected or a plurality of images may be selected.

When an alternative image to be transmitted is selected by the user, the controller 180 may transmit only the selected image to the counterpart (S100, S120), or may include and transmit specific additional information in the selected image (S100, S110). The additional information may include temporal information, spatial and the like of the transmitted image. The display information may be provided using the additional information. In particular, when a plurality of images are transmitted, the images may be transmitted at predetermined time intervals. For example, if there are five images to be transmitted, five images may be repeatedly transmitted at three second intervals.

Hereinafter, the data transmission method of the mobile terminal shown in FIG. 5 will be described in more detail.

6 is a diagram illustrating a display state of a screen when a signal for transmitting a substitute video is input during a video call. In particular, this indicates a case where the ID of the video call counterpart is not stored.

6A illustrates a display state of a screen during a video call. The other party's image is displayed at the top of the screen, and the user's image is displayed at the lower right of the screen. The controller 180 can display an image of a user captured by the camera 121 in real time.

When a signal for transmitting a substitute video is input during a video call, the controller 180 can display an image that can be selected as a substitute video in a thumbnail form (FIGS. 6B and 6C). 6C illustrates a state in which a pop-up window 601 including an image that can be selected as a substitute image is displayed while the video call screen is displayed. In a state where a selectable image is displayed as shown in FIG. 6B or 6C, the user may select an image to be transmitted as a substitute image. The user input for selecting an image may vary depending on the implementation form of the mobile terminal 100. For example, when the display screen is configured as a touch screen, the image to be selected may be touched or in close proximity. There may be a plurality of images selected. When there are a plurality of images selected, the controller 180 may transmit the plurality of selected images to the counterpart at predetermined time intervals. For example, if there are five images to be transmitted, five images may be repeatedly transmitted at three second intervals. It is also possible to transmit with different time intervals. For example, the second image may be transmitted 5 seconds after the first image transmission, and the third image may be transmitted after 3 seconds. The predetermined time interval for transmitting the image and the image may be default or may be set by the user.

As described above, when a plurality of images are transmitted at predetermined time intervals, the receiving terminal may receive the images in a slide format. This may be applied even when the video is transmitted. For example, when a still image is transmitted after the moving image is transmitted, the last frame and the still image of the moving image may be displayed in a slide format.

7 is a diagram illustrating a display state of a screen when a signal for transmitting a substitute video is input during a video call. In particular, it represents a case where the ID of the video call counterpart is stored.

7A illustrates a display state of a screen during a video call. The other party's image is displayed at the top of the screen, and the user's image is displayed at the lower right of the screen. The controller 180 can display an image of a user captured by the camera 121 in real time. In addition, the screen 701 displays information for identifying a video call counterpart. For example, the name and phone number of the video call counterpart may be displayed.

When a signal for transmitting a substitute video is input during a video call, the controller 180 may extract a video related to a video call counterpart ID as a substitute video and display the thumbnail in a thumbnail form (FIGS. 7B and 7C). FIG. 7C illustrates a state in which a pop-up window 703 including an extracted image is displayed while a video call screen is displayed.

The video associated with the call counterpart ID refers to a video that can be identified using the counterpart ID. For example, the controller 180 may extract an image related to the counterpart ID from the phone book. The phone book may store a name, date of birth, address, email address, ringtone, music, image, etc. of a specific counterpart. Also, the controller 180 may extract an image related to the counterpart ID from the storage area related to the video call counterpart. For example, the controller 180 may search for a specific folder related to a specific counterpart and extract an image stored in the found folder. In addition, the controller 180 may extract an image file related to the counterpart image using identification information of the file. The "identification information of a file" is information for identifying a file and may include a file type, a file size, a file name, and a playing time of the file. For example, the user may input an ID of a specific counterpart in a tag portion of an image file name to identify whether the video is associated with a specific counterpart. In this case, the controller 180 inputs the tag portion in the tag portion. The video associated with the ID of the video call counterpart may be extracted using the counterpart ID.

In a state where a selectable image is displayed as shown in FIG. 7B or 7C, the user may select an image to be transmitted as a substitute image. The user input for selecting an image may vary depending on the implementation form of the mobile terminal 100. For example, when the display screen is configured as a touch screen, the image to be selected may be touched or in close proximity. There may be a plurality of images selected. When there are a plurality of images selected, the controller 180 may transmit the plurality of selected images to the counterpart at predetermined time intervals. For example, if there are five images to be transmitted, five images may be repeatedly transmitted at three second intervals. It is also possible to transmit with different time intervals. For example, the second image may be transmitted 5 seconds after the first image transmission, and the third image may be transmitted after 3 seconds. The predetermined time interval for transmitting the image and the image may be default or may be set by the user.

As described above, when a plurality of images are transmitted at predetermined time intervals, the receiving terminal may receive the images in a slide format. This may be applied even when the video is transmitted. For example, if a still image is transmitted after the moving image is transmitted, the last frame and the still image of the moving image may be displayed in a slide format.

In addition, although not shown, the controller 180 may extract an image related to a video call counterpart and automatically transmit all of the extracted images when a key signal for transmitting an alternate image is input. In this case, the screen for selecting the extracted image may not be displayed.

8 is a diagram illustrating an example of extracting an image from a specific storage area associated with a speed dial number of a video call counterpart. In addition, the shortcut number may be associated with the phone number of the counterpart as well as the specific storage area.

When a specific speed dial number is input during a video call, the controller 180 may display a video stored in a folder associated with the specific speed dial number as a thumbnail. For example, when the other party's shortcut number is "1", the controller 180 may display an image stored in "folder 1" according to a key input of "1" during a video call. The user may store only the image related to the counterpart in the "folder 1".

By the above method, the user may conveniently transmit a substitute image related to a specific counterpart through a shortcut number input during a video call.

In addition, the mobile terminal 100 according to an embodiment of the present invention may also transmit additional information when the replacement image is transmitted. For example, an image effect may be inserted into a transmitted image and transmitted. Such an example is shown in FIG. 9.

As illustrated, when the replacement image is selected, the controller 180 may display a pop-up window 901 for selecting whether to insert an image effect automatically or by a user input. When the insertion of an image effect is selected through the pop-up window 901, the controller 180 may include temporal information, spatial information, etc. of the image in the substitute image.

Meanwhile, additional information such as temporal information and spatial information of the transmitted image may be encoded and transmitted in a specific language format. For example, it may be encoded in a synchronous multimedia integration language (SMIL) format. Synchronized Multimedia Integration Language (SMIL) is an XML-based language designed to make it easier for users to synchronize multimedia content such as audio, video, text, and images so that they can be viewed by users. SMIL can add media items (Fade in / out, wipe in / out) for each content by adding attribute items. With SMIL, website creators can easily define and synchronize multimedia elements for presentation or interaction on the web, including video, sound, and still images. On the web today, although it can deliver video, still images, and sound to the user, each element is isolated from the others and cannot interact with other elements without sophisticated programming. SMIL allows site creators to control the time and area of view, even if they send multiple movies, still images and sound separately.

In addition, the display unit 151 of the mobile terminal 100 according to an embodiment of the present invention may be configured as a touch screen. In this case, the controller 180 may recognize handwriting of the user. Therefore, when a specific character is written on the touch screen by the user, the controller 180 may recognize the handwriting of the user as an input of the character. As used herein, a “character” may include letters, symbols, pictures, and the like. The controller 180 may transmit a character written by the user when the substitute image is transmitted. Such an example is shown in FIG. 10.

As shown, the controller 180 can transmit the text written by the user together with the replacement image. For example, in a video call, a user may write specific text by handwriting on an area where the counterpart image is displayed. When a specific signal is input, the controller 180 may transmit the text together with the substitute image. For example, when a key signal for text transmission is input, the controller 180 may transmit the text to the counterpart. Also, the text may be transmitted to the counterpart by touch dragging. For example, when the touch drag is made in the direction of the arrow, the controller 180 may recognize it as a signal input for text transmission.

The controller 180 may transmit the text in the form of an image. For example, the controller 180 may extract and image only the text, or may image the text so that the text is overlapped on the replacement image.

In addition, the mobile terminal 100 according to an embodiment of the present invention may also transmit a specific music when transmitting an alternative image. Such an example is shown in FIG. 9.

The controller 180 may display a pop-up window 1101 for transmitting specific music when the substitute image is transmitted (FIG. 11A). The specific music may be music associated with the counterpart ID. The music associated with the counterpart ID refers to music that can be identified using the counterpart ID. The music related to the counterpart ID may have the same description of the video associated with the video call counterpart ID.

If “Yes” is selected in the pop-up window 1101, the controller 180 may display music related to the counterpart ID (FIG. 11B). In this case, the controller 180 may transmit the music selected by the user to the counterpart. The transmitted music may be stored in the counterpart terminal or played as background music during a video call. The background music playback may be performed in at least one of a user terminal and a counterpart terminal.

In addition, although not shown, when "Yes" is selected in the pop-up window 1101, the controller 180 may automatically transmit all of the music related to the counterpart ID to the counterpart.

FIG. 12 illustrates a state in which an image is displayed at a receiving terminal in which a substitute image is transmitted by the method illustrated in FIGS. 6 to 11.

As shown, the receiving terminal may receive the replacement image and display the slide image. In this case, when additional information of the image is further received by the receiving terminal, a specific effect may appear together on the displayed image.

In addition, according to an embodiment of the present invention, the above-described method may be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (eg, transmission over the Internet). It also includes. In addition, the computer may include the controller 180 of the terminal.
