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.

Meanwhile, the two different cameras 210a and 210b may be configured to photograph images at a predetermined angle of view.

The angle of view may mean a photographing range of a camera (more specifically, a lens included in the camera). At this time, the larger the angle of view of the camera, the shorter the focal length can be. Therefore, when the camera photographs an image with a lens having a large angle of view, the camera can photograph a wide range of images. In addition, when a camera photographs an image with a lens having a small angle of view, a narrow range of images can be photographed.

Depending on the angle of view, the lens can be distinguished as a wide-angle lens, a standard lens, and a telephoto lens. The standard lens is a lens having an angle of view of about 45 degrees and a focal length of about 50 mm. A lens having a large angle of view and a short focal length can be distinguished from a wide angle lens, a lens having a smaller angle of view and a longer focal length than a standard lens can be distinguished from a standard lens by a telephoto lens.

In other words, the respective incidence planes 211a and 211b of the first and second cameras may be arranged substantially parallel. That is, the angle? 1 formed by the incident surfaces 211a and 211b of the first and second cameras may be substantially a square.

Therefore, in the second state, the first and second cameras 210a and 210b can photograph a wider range of regions in the first state. This will be discussed in more detail later with reference to Figs. 10A and 10B.

4A and 4B, the first state 212a and the second camera 212b can be shifted from the first state to the second state by lifting the first and second cameras 212a and 212b by the mounting unit 220, respectively. Likewise, the first state can be switched from the second state to the first state by lowering one side 212a, 212b of each of the first and second cameras by the mounting portion 220. [

Although not shown separately, the incident surfaces 211a and 211b of the first and second cameras are positioned on the left and right sides of the first and second cameras, respectively, based on the degree of lifting and lowering of one side 212a and 212b of the first and second cameras, It is apparent to those skilled in the art that the angle with the outer surface of the body can be adjusted.

At least a part of the second members 222a and 222b is connected to a guide slot 221a formed in the first member 221 so that the first member 221 is moved in the first direction d1 And can linearly move in a second direction (d2) intersecting with the first direction (d1) when linearly moving.

5C, a guide slot 221a may extend along a predetermined direction d in the first member 221. The predetermined direction may be defined by the first and second directions d1 and d2, , d2). < / RTI >

In other words, the guide slot 221a includes second members 222a and 222b connected to the guide slot 221a when the first member 221 linearly moves in the first direction d1 May be formed to be linearly movable in a second direction (d2) intersecting the first direction (d1).

More specifically, the second members 222a and 222b may be formed as a pair to be coupled to the first and second cameras 210a and 210b, respectively.

That is, one of the pair of second members 222a and 222b may be coupled to the first camera 210a and the other may be coupled to the second camera 210b.

Specifically, the pair of second members 222a and 222b may be configured such that the first and second cameras 210a and 210b face each other in the first state 215a and 215b, 2 camera inner surface), respectively. More specifically, the pair of second members 222a and 222b are arranged on the sensor surfaces 214a and 214b of the first and second cameras among the inner surfaces 215a and 215b of the first and second cameras, respectively. 4b). ≪ / RTI >

When the pair of second members 222a and 222b are coupled to the first and second cameras 210a and 210b respectively, 1 and the second cameras 210a and 210b may be rotatably coupled. In other words, the pair of second members 222a and 222b can be rotatably coupled to the first and second cameras 210a and 210b, respectively, through a pair of rotation shafts 224a and 224b .

When the pair of second members 222a and 222b linearly moves in the second direction d2, the entire first and second cameras 210a and 210b are moved in the second direction d2 , Only a part of the first and second cameras 210a and 210b can linearly move along the second direction d2 without performing linear motion along the second direction d2. This will be described in more detail later when the first and second fixing projections are explained.

Meanwhile, guide protrusions 225a and guide grooves 225b may be formed on the opposite sides of the pair of second members 222a and 222b, respectively. Here, the guide protrusion 225a may be formed to be engageable with the guide groove 225b.

A guide protrusion 225a is formed on the second member 222a coupled to the first camera 210a and a guide groove 225b is formed on the second member 222b coupled to the second camera 210b. As shown in Fig.

On the other hand, the surfaces 216a and 216b disposed on the opposite sides of the inner surfaces 215a and 215b of the first and second cameras (hereinafter, referred to as outer surfaces of the first and second cameras) (217a, 217b) may be provided.

More specifically, the first and second fixing protrusions 217a and 217b are formed on the outer surfaces 216a and 216b of the first and second cameras 210a and 210b, respectively, (211a, 211b).

In addition, the first and second fixing protrusions 217a and 217b may be formed to catch at least a part of the terminal body in the second state.

Referring to FIG. 4B, the terminal body facing the first and second fixing protrusions 217a and 217b has first and second grooves 117a and 117b corresponding to the first and second fixing protrusions 217a and 217b, 117b. That is, the first and second fixing protrusions 217a and 217b may be formed to be engaged with the first and second grooves 117a and 117b, respectively, in the second state.

5A to 5C, the rotation mechanism of the first and second cameras 210a and 210b is rearranged so that the rotation of the motor 230 causes the first member 221 to rotate in the first direction d1, < / RTI > The second members 222a and 222b connected to the first member 221 through the guide slot 221a can linearly move along the second direction d2. By the linear motion of the second members 222a, 222b in the second direction d2, one side 212a, 212b of each of the first and second cameras can be lifted.

Meanwhile, the first and second fixing protrusions 217a and 217b continuously extend from the first and second grooves 117a and 117b while the first and second cameras 212a and 212b are being lifted, The first and second cameras 210a and 210b can be rotated relative to the outer surface of the terminal body.

More specifically, the first and second gears 321a and 321b may be configured to rotate in different directions.

For example, although not shown, when either one of the first and second gears 321a and 321b is rotated in one direction in a state where the first and second gears 321a and 321b are directly meshed with each other , And the other one can be rotated in the direction opposite to the one direction.

Alternatively, even when an even number of other gears meshed with each other are disposed between the first and second gears 321a and 321b so as to be engaged with the first and second gears 321a and 321b, The two gears 321a and 321b may be configured to rotate in different directions.

 For example, as shown in FIGS. 6A to 6C, between the first and second gears 321a and 321b, a main gear 323 connected to the motor 230, a main gear 323, And an auxiliary gear 324 which is formed to be engaged with the auxiliary gear 324.

6A, when the main gear 323 is rotated in the counterclockwise direction R1, the auxiliary gear 324 meshing with the main gear 323, the first gear 321a, Can be rotated in the clockwise direction R2. Further, the second gear 321b engaged with the auxiliary gear 324 may be rotated in the counterclockwise direction R1. Accordingly, the first and second gears 321a and 321b can be rotated in opposite directions to each other.

The first and second link members 322a and 322b are engaged with the first and second gears at one end and connected to the first and second cameras 210a and 210b at the other end, .

More specifically, one end of each of the first and second link members 322a and 322b may be formed with a plurality of protrusions so as to engage with the first and second gears 321a and 321b, respectively.

One end of the first and second link members 322a and 322b may be fixed to the first and second cameras 210a and 210b, respectively. In other words, when one end of the first and second link members 322a and 322b is moved by the rotation of the first and second gears 321a and 321b, the first and second cameras 210a and 210b ) Can also be moved together.

The other ends of the first and second link members 322a and 322b may be connected to the first and second cameras 210a and 210b through first and second rotation shafts 325a and 325b.

6C, the first and second rotation shafts 325a and 325b are disposed on opposite sides of the opposite surfaces 215a and 215b in the first state, As shown in FIG. Further, the first and second rotation shafts 325a and 325b may be disposed adjacent to the outer surfaces 216a and 216b and the edges adjacent to the respective incident surfaces 211a and 211b.

The first and second rotation shafts 325a and 325b are coupled to at least a part of the terminal body so that the other ends of the first and second link members 322a and 322b can be fixed.

As shown in FIGS. 6A and 6B, when the first and second gears 321a and 321b are rotated, the first and second link members 322a and 322b rotate One side 212a, 212b of the first and second cameras can be lifted.

Meanwhile, the other ends of the first and second link members 322a and 322b are connected to the first and second cameras 210a and 210b while the first and second cameras 212a and 212b are lifted. The first and second cameras 210a and 210b can be rotated relative to the outer surface of the terminal body.

Meanwhile, referring to FIG. 6C, a motor 230 may be disposed between the first and second cameras 210a and 210b.

In addition, the first and second gears 321a and 321b may be connected to the motor 230. More specifically, the rotational axis of the motor 230 is coupled to the periodic gear 323, and the periodic gear 323 can be coupled to the first and second gears 321a and 321b. Accordingly, the first and second gears 321a and 321b can receive rotational force from the motor 230. [

Up to now, the rotation mechanism of the first and second cameras by the mounting portion has been described in detail.

4A and 4B, the first and second cameras 210a and 210b protrude from the outer surface of the terminal body in the second state. However, the present invention is not limited to this. In other words, in the present invention, the first and second cameras 210a and 210b may not protrude from the outer surface of the terminal body in the first and second states. This will be described more specifically with reference to the drawings.

7 and 8 are conceptual diagrams showing the arrangement relationship between the camera and the transparent member related to the present invention.

Referring to FIG. 7, a transparent member 410 may be mounted on the terminal body. Specifically, the transparent member 410 may be mounted at a position corresponding to the first and second cameras 210a and 210b of the terminal body.

7, contents common to the first and second cameras 210a and 210b are described, so that the term camera 210 is used instead of the first and second cameras 210a and 210b. Use.

More specifically, the camera 210 may be disposed below the transparent member 410 to receive light through the transparent member 410.

According to this structure, since the camera 210 is not directly exposed to the outside, foreign matter can be prevented from being introduced.

In addition, a bracket 420 may be mounted on at least a part of the camera 210.

More specifically, the bracket 420 may be disposed to cover a part of one surface of the camera 210. That is, the bracket 420 may be disposed to cover the edge of the incident surface 211 of the camera. In this case, an adhesive material 430a may be disposed on a portion of the bracket 420 facing the camera 210. [

In addition, the transparent member 410 may be disposed on the bracket 420. In other words, the edge of the transparent member 410 can be seated on the bracket 420. Between the bracket 420 and the transparent member 410, an adhesive material 430b may be disposed. Through the adhesive material, the transparent member 410 can be adhered on the bracket 420.

Referring to FIG. 8, the transparent member 410 may be disposed at a predetermined distance d from the first and second cameras 210a and 210b in the first state. Accordingly, the first and second cameras 210a and 210b may be configured to be rotatable inside the transparent member 420. [

Meanwhile, in the present invention, in order to prevent the gap between the first and second cameras 210a and 210b and the body from being worsened, at least a part of the first and second cameras 210a and 210b may be curved .

Referring to FIG. 8, the facing surfaces of the first and second cameras 210a and 210b in the first state may include first and second curved surfaces 215a and 215b, respectively. More specifically, the first and second curved surfaces 215a and 215b may be convex surfaces convex toward each other.

Particularly, a part of the body may be disposed between the first and second cameras 210a and 210b. Alternatively, fixing members 115a and 115b connected to the mobile terminal body may be disposed between the first and second cameras 210a and 210b. In this case, the fixing members 115a and 115b may be fixed with respect to the mobile terminal body.

The first and second curved surfaces 215a and 215b of the first and second cameras 210a and 210b face the first and second curved surfaces 215a and 215b, 215b, respectively. In other words, when the first and second curved surfaces 215a and 215b are convex surfaces, one side surfaces 116a and 116b of the fixing member may be concave surfaces corresponding to the convex surface.

By the shape of the first and second cameras 210a and 210b and the fixing members 115a and 115b, the gap formed between the first and second cameras and the fixing member can be minimized. As a result, foreign matter can be prevented from entering through the gap formed between the camera and the fixing member.

Meanwhile, according to the present invention, the first and second cameras 210a and 210b can be selectively arranged in parallel in either the longitudinal direction or the width direction of the body. Hereinafter, this will be described in more detail with reference to the drawings.

FIGS. 9A to 9C are conceptual diagrams illustrating the rotation module 430 related to the present invention, and FIG. 9D are conceptual diagrams showing images having various shooting ranges under the control of the rotation module 430 related to the present invention.

Referring to FIG. 9A, on one side of the body, a rotatable rotation module 430 may be mounted. The rotation module 430 may be rotated in a clockwise or counterclockwise direction while maintaining a substantially parallel state with one surface of the body.

The first and second cameras 210a and 210b may be formed on the rotation module 430.

The first and second cameras 210a and 210b are rotated on one side of the body together with the rotation of the rotation module 430 so that the first and second cameras 210a and 210b are aligned along the width direction w or the longitudinal direction 1 of the body .

Referring to FIG. 9A, the first and second cameras 210a and 210b may be arranged along the width direction w of the body. In this state, when the rotation module 430 is rotated clockwise or counterclockwise by about 90 degrees, as shown in (b) of FIG. 9A, the first and second cameras 210a, Can be arranged side by side along the longitudinal direction (l).

When the first and second cameras 210a and 210b are relatively rotated by the mounting portion in a state where the first and second cameras 210a and 210b are arranged along the width direction w of the body, The photographing range can be increased in the width direction w.

When the first and second cameras 210a and 210b are relatively rotated by the mounting unit while the first and second cameras 210a and 210b are arranged along the longitudinal direction 1 of the body, The photographing range can be increased in the longitudinal direction (1).

In the present specification, the first and second cameras 210a and 210b are arranged along one of the width direction w and the longitudinal direction 1 of the body, But is not limited thereto.

That is, in the present invention, the first and second cameras 210a and 210b may be disposed along the diagonal direction of the body, depending on the rotation angle of the rotation module 430, May be possible.

9B, the rotation module 430 may be provided with a circuit board 431 for performing control related to the first and second cameras 210a and 210b.

More specifically, the first and second cameras 210a and 210b are disposed along an arbitrary diameter direction of the rotation module 430, and the remaining areas where the first and second cameras 210a and 210b are not disposed The circuit board 431 may be disposed on the circuit board 431. According to this structure, the first and second cameras 210a and 210b are disposed on the rotation module 430, and the remaining area can be used more efficiently.

9B, the first and second cameras 210a and 210b, as well as the first and second cameras 210a and 210b, are rotated relative to the rotation module 430, A mounting portion 320 mounted to the first and second cameras 210a and 210b may be disposed together.

Further, the rotation of the first and second cameras 210a and 210b by the mounting unit 320 can be controlled independently of the rotation of the rotation module 430. [

Meanwhile, the rotation of the rotation module 430 may be performed manually or automatically.

Referring to FIG. 9C, when the rotation module 430 is rotated manually, a locking structure may be applied to the rotation module 430.

For example, a plurality of grooves for locking may be formed on the side surface of the rotation module 430. At this time, the locking protrusion 433 is coupled to one of the locking grooves 432 through at least a part of the terminal body 105, so that the rotation module 430 can be fixed to the body.

More specifically, after the locking protrusion 433 is released from the first locking groove, after the rotation module 430 is rotated by an external force, the locking protrusion 433 is coupled to the second locking groove again The rotation of the rotation module 430 may be manually performed.

Alternatively, the rotation of the rotation module 430 may be automatically performed by a driving unit (not shown) configured to rotate the rotation module 430.

Furthermore, the control unit 180 according to the present invention can control the driving unit based on a subject image included in an image input through the first and second cameras 210a and 210b.

More specifically, the control unit 180 controls the first and second cameras 210a and 210b based on a subject image included in the image input through the first and second cameras 210a and 210b, And the second cameras 210a and 210b may be disposed in any one of the longitudinal direction (l) and the width direction (w) of the body.

Hereinafter, the case where the terminal bodies 100 are arranged vertically with respect to the direction of gravity will be described in the present specification.

The control unit 180 can specify a subject image by a predetermined method in an image input through the first and second cameras 210a and 210b. The predetermined method may be a method of using outline information or color information of a person or an object which is distinguished from other areas in the image.

The control unit 180 may determine whether the specified subject image is arranged in the horizontal direction or the vertical direction within the image based on the region where the specified subject image is arranged in the image.

The first camera 210a and the second camera 210b are arranged in the width direction w of the body in the case where it is determined that the specified subject image is arranged mainly horizontally in the image, The module 430 may be rotated.

The first camera 210a and the second camera 210b are arranged in the longitudinal direction 1 of the body in the case where it is determined that the specified subject image is mainly arranged vertically in the image, The module 430 may be rotated.

9D, when a first object image (for example, an image corresponding to a horizontal line) is included in the image 910, the controller 180 determines that a larger area on the first object The first and second cameras 210a and 210b may be disposed in the width direction w of the body.

On the other hand, this is based on the case where the terminal body 100 is disposed vertically with respect to the direction of gravity. If the terminal body 100 is disposed horizontally with respect to the gravity direction, The first and second cameras 210a and 210b may be disposed in the longitudinal direction 1 of the body.

9B, when the second image of the object (for example, an image corresponding to a high-rise building) is included in the image 920, the controller 180 may include a wide area on the second object The first and second cameras 210a and 210b may be disposed in the longitudinal direction 1 of the body.

On the other hand, this is based on the case where the terminal body 100 is disposed vertically with respect to the direction of gravity. If the terminal body 100 is disposed horizontally with respect to the gravity direction, The first and second cameras 210a and 210b may be disposed in the width direction w of the body.

Therefore, according to the present invention, as the arrangement of the first and second cameras 210a and 210b is changed by the rotation module 430 based on the object image included in the image, the image suitable for the object is more convenient Can be provided.

Meanwhile, in the present invention, relative rotation of the first and second cameras 210a and 210b by the mounting portion can be controlled more conveniently by the user. This will be described more specifically with reference to the drawings.

FIG. 10A is a flowchart illustrating a method of controlling the relative rotation of the first and second cameras 210a and 210b according to the present invention, and FIG. 10B is a conceptual diagram illustrating the control method of FIG. 10A.

Referring to FIG. 10A, in the control method according to the present invention, through the first and second cameras 210a and 210b, the first and second shooting modes, which are respectively photographed in the first and second shooting modes The step of outputting the image to the display unit 151 may proceed (S1010).

Specifically, when an application related to the dual camera is executed by the user, the control unit 180 can receive the first and second images through the first and second cameras 210a and 210b, respectively. The control unit 180 may combine the first and second images to obtain one composite image, and output the obtained composite image 1040 to the display unit 151. FIG.

4A, the first camera can receive the first image for the first photographing region R1, and the second camera can receive the second image for the second photographing region R2 The second image can be received. At this time, if the first and second images are combined to obtain one composite image, the composite image may correspond to the third photographing region R3, which is the sum of the first and second photographing regions R1 and R2 have.

That is, the composite image may correspond to a range of photographing areas wider than the respective first and second images. Therefore, if both of the first and second cameras 210a and 210b are used, a wider range of images can be obtained than using one camera.

Referring to FIG. 10B, the composite image 1040 output to the display unit 151 may be an image photographed in the first photographing mode. That is, as described above, when the first and second cameras 210a and 210b are arranged in the first state, the first and second cameras 210a and 210b perform shooting One result may be obtained.

After the step S1010, a step of receiving an input of a change of the photographing mode from the user may be performed (S1020).

Referring to FIGS. 10A and 10B, an icon 1050 related to the photographing mode change may be output to the display unit 151. FIG. That is, the icon 1050 may include first and second icons 1051 and 1052 corresponding to the first and second shooting modes, respectively. Any one of the first and second icons 1051 and 1052 may be highlighted so that a photographing mode corresponding to the composite image 1040 currently displayed on the display unit 151 is displayed.

The control unit 180 may display the photographing mode corresponding to one of the first and second icons 1051 and 1052 on the other one of the first and second icons 1051 and 1052, The photographing mode can be switched to the corresponding photographing mode.

In the figure, only the method related to the change of the photographing mode through the icon is shown, but the present invention is not limited thereto. For example, when the composite image corresponding to the first photographing mode is output, the first photographing mode may be changed to the second photographing mode if the terminal body moves according to a preset movement.

In operation S 1020, in response to the input, a step of outputting an image photographed in one shooting mode other than the shooting mode through the display unit 151 may be performed.

Referring to FIG. 10B, in response to the input, the display unit 151 may output an image 1060 photographed in the second photographing mode. The first and second cameras 210a and 210b are disposed in the second state as described above. In this case, the first and second cameras 210a and 210b are disposed in the second state, 210b. ≪ / RTI >

As described above, the first photographing mode may be a mode for photographing an image at a narrow angle as compared with the second photographing mode, and the second photographing mode may be a mode for photographing an image at a wide angle as compared with the first photographing mode.

However, in both of the first and second shooting modes, a mode for shooting an image using both the first and second cameras 210a and 210b is used. In this mode, a wider range than a mode for shooting an image using only one camera It will be appreciated by those skilled in the art that it is possible.

As described above, according to the present invention, rotation of the first and second cameras 210a and 210b by the mounting portion can be more conveniently and intuitively controlled by the user.

Specifically, when an application related to the camera is executed by the user, the control unit 180 can receive the first and second images through the first and second cameras 210a and 210b, respectively. Then, the control unit 180 may output at least one of the first and second images 1110 through the display unit 151. At this time, the first and second images may be moving images.

In addition, the control unit 180 can specify the subject image 1120 in a predetermined manner in the image output to the display unit 151. [ The predetermined method may be a method of using outline information or color information of a person or an object which is distinguished from other areas in the image.

The first and second cameras 210a and 210b according to an embodiment of the present invention are disposed below the transparent member mounted on the body, so that the first and second cameras 210a and 210b can be prevented from protruding outward. Accordingly, the appearance is not hindered by the first and second cameras 210a and 210b.

The first and second cameras 210a and 210b according to an embodiment of the present invention are configured such that the first and second cameras 210a and 210b and the body (Or the fixing member fixed to the body) can be minimized. As a result, foreign matter can be prevented from flowing through the gap.
