The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of regions may be configured to operate in association with one another.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output. When the soft key 151c is touched, a number corresponding to the touched soft key is displayed on the output window 151a. When the first operation unit 116 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

When the soft keys 135c are touched through the touch pad 135, characters, numbers, symbols, etc. corresponding to the touched soft keys are displayed on the output window 135a. As described above, the touch input through the touch pad 135 is advantageous in that it is possible to prevent the soft key 135c from being covered by the finger when touching, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad 135, and the like.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a finger of a user approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

The distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. The proximity signal output from each proximity sensor is simply used by using a plurality of proximity sensors having different detection distances, The depth is known.

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance d2 or more and less than the distance d3, it is recognized as a proximity touch of the third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity and proximity positions of the pointer to the touch screen, and perform various operation controls according to the various input signals.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 155 and 156 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 155 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 156 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 155 and 156 may be configured as a touch screen capable of touch input, respectively.

For example, when a touch (a contact touch or a proximity-touch) to the first display unit or the TOLED 155 is detected, the control unit 180 determines whether the touch At least one of the images displayed in the TOLED 155 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 156 is controlled when touching the TOLED 155 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

In the overlapped state (the mobile terminal is in a closed state), the TOLED 155 is arranged to overlap the lower side of the LCD 156. In this state, if a touch such as a long touch (for example, a touch that lasts for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 155 in advance, ) Causes at least one image of the image list displayed on the LCD 156 to be selected according to the sensed touch input. The result according to the execution of the selected image is displayed on the TOLED 155.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 156 to the TOLED 155 (without performing any action thereto). That is, when the user touches one area of the TOLED 155 corresponding to the specific entity of the LCD 156 for a long time, the controller 180 moves the corresponding entity to the TOLED 155 to be displayed. Meanwhile, the object displayed on the TOLED 155 may also be displayed on the LCD 156 according to a predetermined touch input to the TOLED 155. [ In this figure, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 155. If the drag is detected with the long touch, the control unit 180 displays the drag

As a function associated with the selected image, for example, a preview screen for the image may be displayed on the TOLED 155. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 moves a selection cursor (or a selection bar) of the LCD 156 while the preview screen is being output and the TOLED 155 is further dragged while maintaining the long touch, The selected cursor displays the selected image on the preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch. When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 155 .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

FIGS. 6A and 6B are views referred to the description of a haptic region that generates a haptic effect and an adjacent region in which a proximity signal is detected.

6A shows objects such as icons and menu items in a circular form for convenience of explanation. The area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the center area as shown in FIG. 6A. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

The haptic region in which the tactile effect is generated and the adjacent region in which the proximity signal is detected can be set to be different from each other if the proximity region and the haptic region are simultaneously set in the region where the object is displayed. That is, the haptic region may be set narrower than the adjacent region, or the haptic region may be set wider than the adjacent region. For example, in (a) of FIG. 6A, the area including the first area A and the second area B may be an adjacent area, and the first area A may be set as the haptic area.

As shown in (b) of FIG. 6A, the area where the object is displayed can be divided into three areas A, B, and C, or as shown in FIG. 6A, have. Each divided region can be configured to generate a tactile effect with different intensities or patterns. Even when an area in which one object is displayed is divided into three or more areas, the haptic area and the adjacent area can be set differently according to the use environment.

The size of the adjacent region may be changed according to the position of the display unit 151. That is, as shown in (a) of FIG. 6B, the corresponding adjacent region may be gradually reduced to 'C', 'B', or 'A' depending on the position close to the display unit 151, Conversely, it may be configured such that the corresponding adjacent region gradually increases in accordance with the position close to the display unit 151. [ In this case as well, the haptic area may be set to a fixed size regardless of the position close to the display unit 151, such as the 'H' area shown in FIG. 6B.

In the case of dividing a region in which an object is displayed for setting a haptic region or an adjacent region, in addition to the concentric segmentation as shown in Fig. 6A, segmentation in the horizontal direction or vertical direction, radial segmentation, There are many ways to use it.

7 is a flowchart illustrating a method for providing video call information of a mobile terminal according to an exemplary embodiment of the present invention. 8 is a flowchart illustrating a method of reproducing video call information in a video call information providing method of a mobile terminal according to an exemplary embodiment of the present invention. 9 to 14 are diagrams illustrating a screen to which a method for providing video call information of a mobile terminal is applied according to an embodiment of the present invention.

The method for providing video call information of a mobile terminal according to an embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. 1 to FIG. Hereinafter, a method of providing a mobile path of a mobile terminal according to an embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to FIG. 7 and necessary drawings.

And performs a video call (S210). When the user sets up a call to perform a video call or receives a call request from the opposite terminal, the control unit 180 of the mobile communication terminal 100 receives the call from the opposite terminal through the wireless communication unit 110 And displays the image of the user obtained from the camera unit 121 on the touch screen 151 by controlling the camera unit 121. [ For example, on the lower right side.

The control unit 180 displays the image 12 of the user obtained from the camera unit 121 on the touch screen 151 and transmits the image 12 to the counterpart terminal through the wireless communication unit 110.

On the other hand, in the upper part of the left space of the user image 12, the controller 180 displays a menu for blocking the transmission of the video call and a speaker-shaped icon for displaying the menu for blocking the output of the speaker outputting the video call sound For example, a user image 12 as one of the images stored in the memory unit 160. In addition, the icon image 14 may be displayed on the lower side of the memory unit 160, It is possible to display a substitute image 13 that can be transmitted to the other terminal.

The control unit 180 displays various soft keys 15 used as shortcut keys for matching the specific functions provided by the mobile communication terminal 100 at the lower end of the touch screen 151, can do.

The control unit 180 may display information about the duration of the video call in a space between the counterpart video 11 and the user video 12 displayed on the touch screen 110, for example.

Accordingly, the user can control the environment of the mobile communication terminal 100 using the icons and soft keys displayed while watching the information related to the video and the video communication with the other party's video 11, and perform video communication.

The control unit 180 temporarily stores the video call information for the video 11 of the other party during the video call (S220). Here, the video call information may refer to the video call information of the other party in the video call, and the video call information may include video data and voice data during the video call. The method of temporarily storing the video call information may be performed in various ways.

First, the entire video call performing interval can be temporarily stored at the same time as the start of the video call according to the setting of the user. In addition, the control unit 180 can temporarily store the video call information from the input time of the soft key 15 through the input of a specific soft key 15 during the video call.

In addition, the video data of the video call information can be stored in the form of moving picture or still picture.

Here, when the image data is stored in the form of a moving image, the moving image of the whole section during the video call can be temporarily stored. In addition, if a video of a certain period is temporarily stored during the video call, a video for a specific time period is temporarily stored. If a video having a predetermined amount of time or more is stored, the video of the oldest frame is discarded, have.

For example, if the 5-second moving picture is set to temporarily store according to the user's setting, 5-second moving picture data starts to be stored from the start of the video call. Thereafter, when the amount of stored video temporarily stored exceeds 5 seconds, the video of the oldest frame is discarded and the video of the latest frame is temporarily stored. Thereafter, when the video call ends, the moving picture of 5 seconds before the end of the video call can be temporarily stored.

In addition, when the image data is stored in the form of a still image, the image data of the entire section during the video call can be captured as a still image according to a predetermined period and temporarily stored. For example, if the predetermined period is 3 seconds, the image data of the other party's image 11 can be captured and stored temporarily at a cycle of 3 seconds.

In addition, the image data of a certain section during the video call can be captured as a still image according to a predetermined period and temporarily stored. For example, if the preset capture period is set to 3 seconds, and if it is set to capture and temporarily store only the interval of 15 seconds during the video call, the video data is transmitted at intervals of 3 seconds from the start of the video call. Capture and start to save.

Thereafter, if the video call duration exceeds 15 seconds, the sixth still image is captured and temporarily stored, and then the first captured still image and the temporarily stored still image are deleted. After the still image is captured in this manner, when the video call ends, five still images can be temporarily stored at intervals of 3 seconds from the still image captured 15 seconds before the end of the video call.

The controller 180 determines whether the video call is terminated (S230). If it is determined in step S230 that the video call has not ended, the operation in step S220 is repeated.

If it is determined in step S230 that the video call is terminated, the temporarily stored video call information is played (S240). 8 is a detailed flowchart of a method of reproducing video call information in step S240.

The control unit 180 determines whether the video call information is automatically reproduced after the video call is terminated (S241). The method for reproducing the video call information may be preset according to the setting of the user.

When the video call information is set to be automatically reproduced after the end of the video call, the video call information is automatically reproduced for a time until returning to the idle screen after the video call ends. Referring to FIG. 10, after the video call is terminated, the temporarily stored video call information may be played back on the display unit 151 of the mobile terminal 100. [ The reproduction of the video call information may be displayed together with the video call execution time (00:03:08) with the other party and the telephone number of the video call partner.

The reproduction of the video call information may be reproduced differently according to the type of the temporarily stored video call information. If the temporarily stored video call information is a still image, the temporarily stored still image may be reproduced in a slideshow format. In addition, when the temporarily stored video call information is a moving image, the temporarily stored moving image can be played back together with the temporarily stored audio data.

On the other hand, if it is determined in step S241 that the video call information is not to be automatically reproduced, the display unit 151 of the mobile terminal 100 after the video call ends, as shown in FIG. 11, It is possible to display the reproduction selection screen 16 for the video call information. A predetermined reproduction key 17 capable of inputting a reproduction request signal may be displayed on the reproduction selection screen 16 together. Then, by inputting the play key 17 on the play selection screen 16, a play request signal is generated.

The control unit 180 receives the reproduction request signal (S243). In response to the reproduction request signal, the temporarily stored video call information can be reproduced (S244). On the other hand, referring to FIG. 12, a plurality of thumbnail images 18 may be displayed on the play selection screen 16 for the video call information. When the temporarily stored video call information is a moving image, the plurality of thumbnail images (18) extract a frame at a specific point in the moving image and display a plurality of thumbnail images on the screen. Each of the plurality of thumbnail images 18a, 18b, and 18c may display the playback time of the moving image.

If the controller 180 receives the reproduction request signal through selection of one of the plurality of thumbnail images, the control unit 180 can reproduce the moving image associated with the selected thumbnail image.

After the automatic reproduction of the video call information is completed, the control unit 180 reproduces the video call information in response to the reproduction request signal on the reproduction selection screen 16, or after reproducing the video call information on the reproduction selection screen 16 It is determined whether there is a storage request in any one of the states where there is no request signal (S250).

As a result of the determination in S250, if there is a storage request, the temporarily stored video call information is stored in the memory 160 in association with a specific application (S260). The specific application may be at least one of a phone book, a schedule, and an alarm. Here, the phone book may be an address book or a call list.

FIG. 13 is a view showing an example in which the temporarily stored video call information is linked to a call list, and FIG. 14 is a screen showing an example in which the temporarily stored video call information is linked to an address book.

Referring to FIG. 13, when the controller 180 receives the store request signal after reproducing the video call information, the controller 180 stores the call list and the temporarily stored video call information in association with each other. The number / call information of the video caller and the video call information temporarily stored at the time of performing the video call with the other party are displayed together in the call list. The video call information may be stored in the form of a thumbnail image (19). Thereafter, the user selects the thumbnail image 19 for the specific party on the call list, thereby allowing the video call information stored at the time of video communication with the other party to be confirmed in the slide show format or moving picture playback do.

Referring to FIG. 14, when the controller 180 receives the store request signal after playing the video call information, the controller 180 stores the address book and the temporarily stored video call information together with the subscriber information of the video call partner . For example, if there is no video call information stored in the address book of the video call destination, the video call information may be stored in the address book of the other party in the form of a thumbnail image (19). Also, even if there is video call information stored in the address book of the video call destination, the latest video call information can be updated and stored. Here, the subscriber information may be at least one of a phone number and a name of the other party.

Thereafter, the user selects the thumbnail image 19 for the specific party on the address book, thereby enabling the video call information stored at the time of the video call with the other party to be confirmed through the slideshow format or moving picture playback .

Although not shown, a specific application may be applied to a schedule, an alarm, a memo, etc. in addition to a phone book (address book, call list), and may be applied to applications other than the listed applications.
