Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a corresponding sensing signal. The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is arranged to scan the motion of the object to be sensed proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

The cases constituting the external appearance of the mobile terminal may be formed by injection molding synthetic resin or may be formed of metal such as stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

The mobile terminal 100 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, a universal mobile terminal 100 in which a synthetic resin or metal is connected from the side to the rear side can be realized.

Meanwhile, the mobile terminal 100 may include a waterproof unit (not shown) for preventing water from penetrating into the terminal body. The mobile terminal 100 is provided with a display unit 151, first and second sound output units 152a and 152b, a proximity sensor 141, an illuminance sensor 142, a light output unit 154, Cameras 121a and 121b, first and second operation units 123a and 123b, a microphone 122, an interface unit 160, and the like.

The display unit 251 according to the present invention may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means may be provided in the flexible display unit 251 or the case to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case accommodating the flexible display unit 251. The case may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, a battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 due to an external force, taking into account the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

In the mobile terminal according to the present invention, the rolled-up display portion is housed in a dried state. The user can expose or store the display unit by applying an external force to the mobile terminal.

FIGS. 2A, 2B, and 2C are conceptual diagrams illustrating a rolled mobile terminal according to an embodiment of the present invention.

FIG. 2B is a perspective view showing the mobile terminal in the open state in which the display unit is exposed from the body part, FIG. 2C is a perspective view of the mobile terminal in the open state As shown in FIG.

The mobile terminal 200 of the present invention includes first and second body parts 201, 202. The first and second body portions 201 and 202 extend in the first direction D1 and are spaced apart from each other based on a tension applied in a direction intersecting the first direction D1.

One surface of the first body part 201 and one surface of the second body part 202 may be in contact with each other in a closed state. May extend along the first direction D1 such that the lengths of the first and second body portions 201 and 202 are substantially equal. For example, the shape of the one surface of the first body part 201 may correspond to the shape of one surface of the second body part 202.

As shown in FIG. 2A, in the closed state, the display unit 251 may be housed in at least one of the first and second body parts 201 and 202 and may not be exposed. This is to prevent the display unit 251 from being damaged by the external environment.

Hereinafter, for the sake of convenience, the display unit 251 is housed in at least one of the first and second body units 201 and 202 in the closed state, Explanation, but not limited thereto. In another exemplary embodiment, the predetermined area of the display unit 251 may be exposed without being housed in the first and second body units 201 and 202 in the closed state. In this case, the user can check the information related to the event occurring in the mobile terminal even in the closed state through the predetermined area.

The first body part 201 and / or the second body part 202 of the mobile terminal 200 includes a guide unit for guiding the display part to be folded and stored. When the guide unit is provided in the first body part 201, the guide unit extends along the first direction D1, and the guide unit 300 is accommodated in the first body part 201, Space.

The mobile terminal 200 may further include a stylus pen 900 accommodated in the first body 201. The stylus pen 900 may extend along the first direction D1 and may be received in the first body 201 along the first direction D1. The stylus pen 900 is formed to be detachable from the first body part 201 based on the external force of the user.

The end of the stylus pen 900 may be exposed to the outside of the first body 201 in a state of being housed in the guide unit. The user can separate the stylus pen 900 from the first body part 201 by applying a force to the stylus pen 900 exposed from the first body part 201. [

One end of the display unit 251 is fixed to the first body 201 by the guide unit 300 so that the other end of the display unit 251 can be rolled, As shown in FIG. When the distance between the first and second body parts 201 and 202 is shortened, the display part 251 is gradually dried by the guide module 300, .

The first and second body parts 201 and 202 are spaced apart from each other based on a tension applied in a direction intersecting the first direction D1 and between the first and second body parts 201 and 202 The display unit 251 is exposed. As the first and second body portions 201 and 202 are moved away from each other due to the external force, the area of the display portion 251 exposed increases.

The first body 201 may include a transparent portion 203 made of a transparent material so that a portion of the display portion 251 is exposed. The image projected by the transparent portion 203 can be confirmed in an area of the display unit 251 housed in the first body 201.

The display unit 251 may be formed integrally with a touch sensor unit for receiving a touch input of a user. Accordingly, the touch sensor included in the display unit 251 can sense the touch input applied through the transparent portion. An independent touch sensor may be included on the transparent portion 302.

The display unit 251 may be formed integrally with a touch sensor unit for receiving a touch input of a user. Accordingly, a touch sensor included in the display unit 251 can sense a touch input applied through the transparent portion 203. [ For example, in the closed state, the control unit determines that one area of the display unit 251 corresponding to the transparent portion 203 is in the closed state, the current state information of the mobile terminal 200 (current time, Etc.), received event information, and the like. At this time, the remaining region except for one region of the display unit 251 corresponding to the transparent portion 203 can be kept off in the closed state. Thereby, unnecessary power can be prevented from being wasted.

The second body part 202 may be provided with an acoustic output part 252.

Referring to FIG. 2B, one end of the display unit 251 is fixed to the first body 201, and the other end of the display unit 251 is fixed to the second body 202. Accordingly, the user can grasp the first and second body parts 201 and 202 by hand and expose the display part that is curled and stored inside the first and second body parts 201 and 202.

The display unit 251 displays (outputs) information processed by the mobile terminal 100 in the open state. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

In addition, the display unit 151 may exist in two or more depending on the embodiment of the mobile terminal 100. In this case, the mobile terminal 100 may be provided with a plurality of display portions spaced apart from each other or disposed integrally with one another, or may be disposed on different surfaces, respectively.

The display unit 151 may include a touch sensor that senses a touch with respect to the display unit 151 so that a control command can be received by a touch method. When a touch is made to the display unit 151, the touch sensor senses the touch, and the control unit 180 generates a control command corresponding to the touch based on the touch. The content input by the touch method may be a letter or a number, an instruction in various modes, a menu item which can be designated, and the like.

The touch sensor may be a film having a touch pattern and disposed between the window 151a and a display (not shown) on the rear surface of the window 151a, or may be a metal wire . Alternatively, the touch sensor may be formed integrally with the display. For example, the touch sensor may be disposed on a substrate of the display or inside the display.

In this way, the display unit 151 can form a touch screen together with the touch sensor. In this case, the touch screen can function as a user input unit 123 (see FIG. 1A). In some cases, the touch screen may replace at least some functions of the first operation unit 123a.

Meanwhile, the controller controls the display unit to display information on the exposure range of the display unit 251 in the open state (exposure limit information of the display unit) in one area corresponding to the transparent unit 203 .

In the opened state, the stylus pen 900 can be separated from the first body 201.

Referring to FIG. 2C, a first camera 121a and a second camera 121b may be disposed on a rear surface of the mobile terminal. Specifically, the first camera 121a is disposed on the first body 201, and the second camera 121b is disposed on the second body 202. FIG.

However, these configurations are not limited to this arrangement. These configurations may be omitted or disposed on other surfaces as needed. For example, the first camera 121a is provided on a side surface of the first body part 201 rather than on the rear surface thereof, and the second camera 121b is also provided on a side surface of the second body part 202, As shown in FIG.

The first camera and the second camera 121a and 121b process an image frame of a still image or a moving image obtained by the image sensor in a photographing mode or a video communication mode. The processed image frame can be displayed on the display unit 151 and can be stored in the memory 170. [

3 is a conceptual diagram for explaining roll-out and roll-in in a mobile terminal according to the present invention.

The first body part 201 and the second body part 202 may move in a direction toward or away from each other by a user gesture due to the characteristics of the rolled mobile terminal.

For example, in a state where the first body part 201 is fixed, the second body part 202 can move toward the first body part 201 (or in the second direction D2). In this case, at least one area of the display unit 251 exposed is accommodated in the guide unit. Roll-in 'means that at least one area of the display unit 251 is accommodated in the guide unit by the movement of at least one of the first body unit 201 and the second body unit 202 define. The open state may be switched to the closed state by the roll-in.

In another example, in a state where the first body part 201 is fixed, the second body part 202 can move in the third direction D3. In this case, at least one area of the display unit 251 housed in the guide unit is exposed outside the guide unit. Roll out "that an area of the display unit 251 is exposed to the outside of the guide unit by movement of at least one of the first body unit 201 and the second body unit 202, '. The closed state can be switched to the open state by the roll-out.

The first camera 121a is provided in the first body 201 and the second camera 121b is provided in the second body 202. [ Accordingly, the first camera 121a and the first camera 121b have substantially the same photographing direction. Specifically, when the photographing direction of the first camera 121a is defined as the first photographing direction and the photographing direction of the second camera 121a is defined as the second photographing direction, the first and second photographing directions are defined as Parallel to other axes.

A first image may be generated by the first camera 121a, and a second image may be generated by the second camera 121b. Furthermore, the controller may control the display unit 251 to output at least one of the first and second images. The control unit may control the display unit 251 such that at least one of the entire areas of the display unit 251 is output to at least one area (hereinafter, referred to as 'display area') not accommodated in the first and second body units 201 and 202 And controls the display unit 251. At this time, the display area outputs the at least one in a turned-on state, and the remaining areas except for the display remain turned off.

If the roll-out or the roll-in occurs during the output of the at least one, the controller 180 adjusts the display area. The controller 180 may adjust the display area based on the base line BL. And enlarges or reduces the at least one size in the output according to the adjusted display area.

For example, the rolled-up mobile terminal can be switched to the state shown in Fig. 3 (c) by roll-out in the state shown in Fig. 3 (b). In this case, the display area is adjusted, and the size of at least one of the first and second images is also adjusted to correspond to the adjusted display area.

Meanwhile, when at least one of the first image and the second image is displayed in the display area, the control unit may control the graphic object to receive the shooting command so as not to overlap with the at least one. For example, as shown in FIG. 3B, when at least one is displayed in a part of the display area, a graphic object to receive the photographing command is displayed in the remaining area except for the part of the area . 3, if there is no space to display the graphic object to receive the photographing command in the display area, the control unit controls the light projecting unit 203 to photograph The display unit 251 may be controlled so that a graphic object to receive the command is displayed. Thereby, the user can more conveniently apply the shooting command to the mobile terminal.

When the roll-out or the roll-in occurs, the distance between the first camera 121a and the second camera 121b is variable. Different functions must be performed for the first image received from the first camera 121a and the second image received from the second camera 121b in accordance with the change in the distance.

Hereinafter, the distance between the first camera 121a and the second camera 121b will be referred to as 'baseline (BL)'.

As the base line BL is shorter, the first image and the second image can be overlapped with each other. Accordingly, the controller can perform the function of enhancing the image quality by synthesizing the first and second images. For example, when the base line BL is smaller than the reference distance, the controller 180 can perform a high dynamic range (HDR) function, a super resolution (SR) function, and a noise reduction (NR) function.

In contrast, as the base line BL is longer, the first image and the second image can be overlapped with each other relatively narrowly. In this case, because the overlapping area between the first and second images is small, the image quality can not be enhanced for the overlapping area, so that the function of enhancing the image quality by combining the first and second images is inefficient do. However, if the baseline BL is greater than or equal to the reference distance, a three-dimensional image can be generated in consideration of the binocular parallax using the first and second images. Accordingly, when the base line BL is greater than or equal to the reference distance, the controller 180 can perform a function related to the three-dimensional image.

The three-dimensional image may be referred to as a three-dimensional stereoscopic image. The three-dimensional image is an image that allows the user to feel the progressive depth and reality of the object placed on the monitor or screen to be the same as the real space. Three-dimensional images are implemented using binocular disparity. The binocular parallax means the parallax caused by the positions of two eyes, which are about 65 millimeters apart. When two eyes see two different images and the images are transmitted to the brain through the retina and are fused, the depth and real feeling of the stereoscopic image are felt .

The three-dimensional display method includes a stereoscopic method (eyeglass method), an autostereoscopic method (non-eyeglass method), and a projection method (holographic method). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method. The autostereoscopic method, which is widely used in mobile terminals, includes a parallex barrier system and a lenticular system. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images include left images (left eye image) and right images (right eye image). A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

The three dimensional depth or three dimensional depth value means an index representing the difference in three dimensional distance between objects in the image. For example, when a depth of three-dimensional depth is defined as 256 levels and the maximum value is 255 and the minimum value is 0, the higher the value, the closer to the viewer or the user.

The three-dimensional depth sense may be defined at different levels according to the baseline BL. For example, when the baseline BL has a first length, a three-dimensional image defined as an X level may be generated. When the baseline BL has a second length that is longer than the first length, a three-dimensional image that is defined as a Y level larger than the X level may be generated. As the base line BL is longer, the three-dimensional depth sense is enlarged, and the shorter the base line BL is, the smaller the three-dimensional depth sense is. In other words, as the baseline BL increases, the maximum depth sense that a user experiences in a three-dimensional image increases proportionally.

Since the base line BL may be different, the rollerable mobile terminal according to the present invention may selectively display graphic objects related to the 3D image according to the base line BL.

Hereinafter, a control method of the rolled mobile terminal that performs different controls according to the base line BL will be described in detail.

FIG. 4 is a flowchart for explaining a control method of the rolled mobile terminal, and FIG. 5 is a flowchart illustrating a method of controlling a display unit such that at least one of a first image received from a first camera and a second image received from a second camera is output Fig.

First, the controller 180 controls the display unit to output at least one of a first image received from the first camera 121a and a second image received from the second camera 121b in the open state S410).

When the control unit 180 is switched from the closed state to the open state, the control unit 180 can automatically execute the photographing application and output the execution screen to the display area. Alternatively, when an execution command for the imaging application is received, the execution screen may be output to the display area. The execution image includes at least one of the first image and the second image.

Referring to FIG. 5, the controller may display at least one of the first image and the second image in the display area in various ways.

For example, either the first image or the second image may be displayed alone. In other words, either one of the first image or the second image may be output to the display area, and the other output may be restricted. In this case, information indicating which one of the first camera and the second camera is photographed may be displayed on the display area together with any one of the first and second cameras.

In another example, the first image may be displayed in a first area of the display area, and the second image may be displayed in a second area different from the first area.

In another example, the controller 180 may output a three-dimensional image (see the 'third image' in FIG. 4) to the display area in consideration of the binocular parallax using the first and second images. Specifically, the control unit may extract overlapping regions from the first and second images, and output a three-dimensional image using the extracted regions.

In another example, the controller 180 may combine the first and second images to generate a new image. A panoramic image such as a fourth image may be generated or a fifth image (not shown) having the same horizontal / vertical length as the first and second images may be generated by combining the first and second images. The fifth image may mean an image having an improved image quality by combining the first and second images.

Consequently, at least one of the first to fifth images may be displayed in the display area. The mobile terminal according to the present invention may provide a user interface configured to selectively output at least one of the first to fifth images. That is, any one of the first to fifth images may be output and may be switched to another by a user request.

Next, the controller 180 displays graphical objects related to the photographing on the at least one based on the distance between the first camera 121a and the second camera 212b (S430). In other words, the graphical objects displayed on the at least one of the graphic objects vary depending on the base distance BL.

The controller may include a sensing unit configured to sense the base line BL, and the control unit may include a sensing unit configured to sense the at least one graphic object based on the base line BL sensed by the sensing unit, Respectively.

According to one embodiment, when the base line BL is greater than or equal to a predetermined distance from which a three-dimensional image can be generated using the binocular parallax, guidance information for guiding the photographing of the three- May be displayed on at least one of the above. For example, the guide information may be text or images such as '3D'.

If the base line BL becomes smaller than the predetermined distance while the guide information is being displayed, the control unit controls the display unit 251 so that the guide information disappears. In other words, the guide information is displayed only when the three-dimensional image capturing is possible based on the baseline BL.

The predetermined distance may vary depending on the distance between any one of the at least one subject and the mobile terminal.

Specifically, the controller focuses the first camera 121a and the second camera 121b on any one of the at least one subject. At this time, the controller can calculate the distance between the focused object and the mobile terminal. For distance calculation, the mobile terminal may further include a distance measuring unit for measuring a distance between the focused object and the mobile terminal.

The control unit calculates a predetermined distance for capturing a three-dimensional image based on the focused object based on the calculated distance. Further, the control unit compares the calculated predetermined distance with the base line (BL), and determines whether to output the guide information according to the comparison result.

The optimum baseline BL may be calculated based on the focused object. In this case, the controller may set the terminal state to a first state in which the base line BL can not generate a three-dimensional image, a second state that is capable of generating a three-dimensional image but is not the optimal base line, It can be classified into the third state which is the optimal baseline, and it can be determined which state the current state is in.

The guide information may be different images according to the terminal status. Here, different images mean images having different shapes, lengths, colors, and the like, for example. For example, the control unit displays the guide information in a first color in the first state, a second color in the second state, and a third color in the third state. The user can check the terminal status based on the color of the guide information.

When a plurality of subjects are included in the image displayed on the display area, one of the plurality of subjects may be focused by user input. When the focused subject is changed, It will not be output or output. In other words, each time the focus is changed, the control unit recalculates a predetermined distance for taking a three-dimensional image based on the focused object, and determines whether to output the guidance information.

Accordingly, the user can adjust the interval between the first camera and the second camera using the characteristics of the rolled mobile terminal, and can confirm whether or not the three-dimensional image can be photographed from the guidance information displayed on the display unit. The user can easily take a two-dimensional image or a three-dimensional image by adjusting the base line BL.

In order to provide user convenience in photographing, the control unit may display at least one of the distance between the focused object and the mobile terminal, and the base line BL in the display area.

Hereinafter, various embodiments in which the control unit controls graphic objects related to photographing based on the base line BL will be described in detail.

6, 7A, 7B, 7C, and 7D are conceptual diagrams for explaining the control method of FIG.

6, when displaying at least one of a first image received from the first camera 121a and a second image received from the second camera 121b, the first camera 121a, Based on the distance (or baseline) between the first camera 121a and the second camera 121b.

More specifically, the control unit displays graphical objects included in the first group on the at least one of the base lines BL when the base line BL is smaller than a preset reference distance, Or may display graphical objects contained in the second group on the at least one. That is, the functions related to the photographing are divided into the functions that can not be performed while the baseline BL increases or decreases, and the functions that can be performed. The graphic objects corresponding to the functions that can not be performed disappear from the display area, The graphic object corresponding to the function is displayed in the display area.

The graphic objects included in the first group correspond to the functions related to the two-dimensional image processing, and the graphic objects included in the second group correspond to the functions related to the three-dimensional image processing considering the binocular disparity .

For example, as shown in FIG. 6A, the first group includes two-dimensional imaging, high dynamic range (HDR), super resolution (SR), noise reduction And at least one of graphic objects corresponding to the 3D panoramic imaging. The graphic objects included in the first group are related to a function of processing a two-dimensional image.

Alternatively, as shown in FIG. 6 (b), at least one of graphic objects corresponding to three-dimensional image capturing, 3D HDR, 3D NR, and three-dimensional panoramic photographing in consideration of binocular disparity . The graphic objects included in the second group are related to the function of processing a three-dimensional image.

The control unit selectively displays graphic objects included in the first group or graphic objects included in the second group when the base line BL is changed while the at least one is output.

For example, when the base line BL becomes smaller than the reference distance while displaying graphic objects included in the second group, the control unit controls the graphics objects included in the second group to disappear, Instead, the graphic objects included in the first group are displayed on the at least one. On the other hand, when the base line BL is larger than the reference distance while displaying graphic objects included in the first group, the control unit controls the graphics objects included in the first group to disappear, 2 < / RTI > above the at least one.

When a touch is applied to any one of the graphic objects displayed in the display area, the control unit can activate / deactivate the function corresponding to any one of the graphic objects. For example, when a touch is applied to a graphic object corresponding to a high dynamic range (HDR) function, the HDR function is activated or deactivated.

6 (c), when the base line BL is extended, the subject is captured in only one of the first camera 121a and the second camera 121b, and the other one It may not be captured. In this case, since the three-dimensional image can not be generated with respect to the subject, the control unit controls the display unit 251 so that any one of the first image and the second image, including the subject, ).

An indicator for guiding the direction in which at least one of the first body 201 and the second body 202 should move in order to capture a three-dimensional image of the subject may be displayed on the display area. For example, when an object is captured only in the first camera 121a, the indicator is guided to roll-in the second body 202 while the first body 201 is fixed Can be output. Accordingly, the user can check the photographing ability of the three-dimensional image in real time, and if the three-dimensional image can not be photographed, the user can quickly switch to a state in which the three-dimensional image can be photographed using the indicator.

If the base line BL is smaller than the reference distance, the control unit displays at least one of the at least one base line BL as a two-dimensional image, and if the base line BL is greater than or equal to the reference distance, The image and the second image can be displayed as a three-dimensional image in consideration of binocular parallax.

For example, as shown in FIG. 7A, when the base line BL has a first length L1 and the first length L1 is smaller than the reference distance, And display the included graphic objects on the display area. In this case, at least one of the first image and the second image is displayed on the display area as a two-dimensional image.

When the base line BL is smaller than the reference distance, capturing of a three-dimensional image is not possible, so that the display of the graphic objects corresponding to the functions related to the three-dimensional image processing is limited.

7B, if the base line BL has a second length L2 and the second length L2 is greater than or equal to the reference distance, The graphic objects included in the second group can be displayed on the display area. In this case, the controller outputs the three-dimensional image to the display area using the first image and the second image.

 According to the base line BL, a two-dimensional image may be output to the display area or a three-dimensional image may be output. Since the image output to the display area according to the base line BL is selectively output as a two-dimensional image or a three-dimensional image, the user can easily capture a two-dimensional image by adjusting the base line BL, So that the user can take a picture.

On the other hand, when the base line BL is larger than the reference distance, not only a three-dimensional image but also a two-dimensional image can be photographed. In this case, the control unit may provide a user interface to select a two-dimensional imaging or a three-dimensional imaging. For example, referring to FIG. 7B, when a touch is applied to the two-dimensional image capturing icon 710, at least one of the first and second images is output as a two-dimensional image, Dimensional image using the first and second images when a touch is applied to the first and second images.

On the other hand, assuming that the terminal and the subject are fixed, the depth sense of the three-dimensional image formed by the first image and the second image changes according to the change of the base line BL.

The control unit may calculate a disparity in the base line BL and calculate a depth of the corresponding three-dimensional image. The depth sense of the three-dimensional image and the baseline (BL) are proportional. Accordingly, as the base line BL increases, the maximum depth sense that a user experiences in a three-dimensional image increases proportionally.

When the controller outputs the three-dimensional image using the first image and the second image, the controller can guide the depth of the three-dimensional image being output to the display area. More specifically, the control unit may calculate a depth sense of the three-dimensional image formed by the base line BL and display depth information for guiding the calculated depth sense on the display area.

The depth information 722 may be displayed in a graphical form.

More specifically, the control unit measures the distance between the focused object and the mobile terminal using the distance measuring unit, and calculates the maximum depth value of the three-dimensional image that can be generated based on the measured distance. 0 and the depth information can be displayed in the coordinate corresponding to the depth value of the 3D image currently being photographed in the generated axis.

Thereby, the user can confirm not only the depth feeling of the currently captured three-dimensional image but also the maximum depth feeling that can be produced. In addition, the user can adjust the base line BL so that a depth feeling desired by the user is generated while checking the depth information.

Referring to FIG. 7C, as the base line BL is continuously expanded, a subject photographed in a three-dimensional image escapes from a field of view (FOV) of the first and second cameras 121a and 121b . In this case, the controller may display a message indicating that the three-dimensional image can not be photographed on the display area, and display the indicator 730 when the base line BL is reduced.

Alternatively, as shown in FIG. 7D, as the base line BL is continuously expanded, a subject photographed in a three-dimensional image is displayed on any one of the first and second cameras 121a and 121b FOV), and it may not disappear in the other clock (FOV).

In this case, the control unit may control the display unit 251 so that an image received from one of the above is displayed on the display area, and an image received from the other is not displayed on the display area.

When one of the objects included in the 3D image disappears from any one of the first and second cameras 121a and 121b during the output of the 3D image, a two-dimensional image is displayed instead of the 3D image do. Any one of the subjects may be a subject to which the first and second cameras 121a and 121b are focused among the subjects included in the three-dimensional image.

Further, the control unit may include a message 740 informing that the two-dimensional image is being output, a message 750 informing the type of the camera (the first camera or the second camera) that has captured the two-dimensional image, A message 760 indicating that the photographing of the image can not be performed can be displayed on the display area.

Although not shown in the drawing, the control unit terminates the at least one display and controls the entire area of the display unit to be turned off when the open state is switched to the closed state while the at least one is being output.

FIG. 8 is a view for explaining an embodiment in which graphical objects displayed on the display unit are changed according to a focused object.

The controller may include a sensing unit configured to sense the base line BL, and the control unit may include a sensing unit configured to sense the at least one graphic object based on the base line BL sensed by the sensing unit, Respectively.

According to one embodiment, when the base line BL is smaller than a predetermined distance that can generate a three-dimensional image using the binocular disparity, the control unit displays graphical objects included in the first group, If greater than or equal to, the graphical objects included in the second group may be displayed.

The predetermined distance varies depending on the distance between any one of the at least one subject and the mobile terminal. The subject may be a subject focused on the first and second cameras 121a and 121b have.

More specifically, a plurality of subjects may be included in a first image received from the first camera 121a and a second image received from the second camera 121b. The controller may focus the first and second cameras 121a and 121b on at least one of the plurality of subjects. When focused, a graphics object that guides the focused subject may be displayed in the display area.

Furthermore, it is possible to calculate a predetermined distance based on the focused object, and to calculate the distance between the calculated graphical objects included in the first group or the graphic objects included in the second group based on the calculated distance and the base line BL Is displayed on the display area.

For example, as shown in FIG. 8, when a banner included in only the clock (FOV) of the first camera 121a is focused, it is impossible to photograph a three-dimensional image with respect to the banana, Graphic objects corresponding to functions related to processing are displayed in the display area, and display of graphic objects corresponding to functions related to the three-dimensional image processing is limited.

A message 810 informing the photographing of the two-dimensional image and a message 820 informing the camera photographing the image being output may additionally be displayed in the display area.

Meanwhile, when a touch is applied to a region where apples other than the banana are displayed, the control unit controls the first and second cameras 121a and 121b to focus on the apples. Since the apples can be photographed in three-dimensional images, graphic objects corresponding to the functions related to the two-dimensional image processing disappear, and graphic objects corresponding to the functions related to the three-dimensional image processing are displayed on the display area.

Since the graphical objects related to the shooting are different depending on the focused object, a new effect is generated in which the user's convenience is increased.

FIGS. 9 and 10 are diagrams for explaining a method of outputting an indicator for assisting in capturing a three-dimensional image.

When capturing a three-dimensional image, the control unit selects one of the plurality of subjects as a reference according to a predetermined reference, and selects one of the first and second And controls the cameras 121a and 121b.

The control unit may calculate a disparity in the base line BL and calculate a depth of the corresponding three-dimensional image. Then, the depth value of the focused object can be calculated.

In the case of outputting or generating a three-dimensional image, the controller may display a depth value of a subject having a maximum depth perception and a depth value that the focused object has on the display area.

9, the controller measures the distance between the focused object and the mobile terminal using the distance measuring unit, calculates a maximum depth value of the three-dimensional image that can be generated based on the measured distance, . 0 and a graphical object 912 in the coordinates corresponding to the depth value of the 3D image currently being photographed in the generated axis. For example, when the focused subject is located at the convergence point with the depth sense of the three-dimensional image at the 255 level, the depth value of the focused object corresponds to level 126, and the axis 910 The graphical object 912 is displayed at the center of the graphical object 912.

Meanwhile, the graphic object 912 may be configured to adjust the 3D depth value of the subject. The controller sets a 3D depth value of the subject based on a touch input applied to the graphic object 912 and controls the first camera to have the set 3D depth value in the 3D image, A baseline indicator 920 for calculating the distance between the first camera 121a and the second camera 121b and guiding the distance between the first camera 121a and the second camera 121b by the calculated distance, Can be displayed on the display area.

For example, if the set 3D depth value is greater than the current 3D depth value, a baseline indicator may be displayed to induce roll-out so that a deeper depth is generated. Alternatively, if the set three-dimensional depth value is less than the current three-dimensional depth value, a baseline indicator may be displayed that induces a roll-in such that a smaller depth of view is generated.

The rollable mobile terminal according to the present invention may further include a distance measuring unit for measuring a distance to the focused object, and the control unit controls the focusing unit such that the focused object has the set 3D depth value in the 3D image A distance between the first camera and the second camera may be used in calculating the distance between the first camera and the second camera.

On the other hand, it may happen that the first camera 121a and the second camera 121b can not be separated by the calculated distance due to physical constraints. In this case, the control unit may notify the user that the roll-out state is the maximum roll-out state in at least one of a visual, auditory, and tactile manner. The distance indicator may further include a distance indicator for calculating the distance between the subject and the mobile terminal for allowing the subject to have the set 3D depth value in the 3D image and guiding the subject and the mobile terminal to be spaced apart by the calculated distance Can be displayed on the display area. For example, a distance indicator such as 'Move back 10m' or 'Move forward 1m' may be displayed in the display area.

Meanwhile, when the display unit 251 is flexible, the user may apply an external force to the first and second bodies 201 and 202 to bend the display unit 251. When the display unit 251 is bent, the first and second cameras 121a and 121b are oriented in different directions.

When a convergence point is designated for a certain object, it may occur that the object can not be expressed in three dimensions due to the angle of view of the first and second cameras 121a and 121b. In particular, in the case of a short-range subject, the baseline BL of the binocular disparity can not be secured, so that a three-dimensional image can not be captured.

In this case, as shown in FIG. 10, the control unit can calculate the direction and angle at which at least one of the first and second cameras 121a and 121b should be bent so that a throttle point is designated for the subject . Further, a notification message may be output to the display area so that at least one of the first and second cameras 121a and 121b is bent in the calculated direction and angle.

The control unit may receive a first image received from the first camera 121a, a second image received from the second camera 121b, and a second image received from the first camera 121a, And the third image newly generated using the two images can be stored as different files. At this time, the distance between the first camera 121a and the second camera 121b may be stored as the metadata of the third image.

The present invention described above can be embodied as computer-readable codes on a medium on 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 the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
