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 uses 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, Detection.

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 adapted to scan the movement of the object to be detected 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.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

[ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Meanwhile, in the present invention, information processed in the mobile terminal can be displayed using a transparent display. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a conceptual diagram for explaining another example of a mobile terminal including a transparent display unit according to the present invention.

As shown, the display unit 251 may be formed of a transparent material. Since the transparent display unit 251 transmits light, the user can see the opposite side through the transparent display unit 251. In general, the transparent display unit 251 may be implemented with a transparent LCD (Liquid Crystal Display) or a transparent OLED (Organic Light Emitting Diode). The way in which transparent LCD displays is similar to the conventional LCD method. However, in order to implement a transparent display module, a transparent LCD can transmit all light to a portion without content. In the above-described manner, the transparent LCD may be implemented such that a portion where a content exists in a display screen is output as a content, and a portion where no content exists is transparent so as to transmit light. Transparent OLED displays are similar to OLED. Like transparent LCDs, transparent OLEDs can transparently display the display by transmitting all light over the content-free areas.

In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

Meanwhile, the transparent display unit 251 may be combined with a touch sensor to implement a transparent touch screen. When a touch is made to the transparent touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input.

The mobile terminal 200 including the transparent display unit may include first and second cameras 221a and 221b and a distance sensor 243. In one embodiment, the first and second cameras 221a and 221b may be disposed toward the second direction, and the distance sensor 243 may be disposed toward the first direction. The distance sensor 243 may be implemented by a laser type sensor, an ultrasonic type sensor, an infrared type sensor, a camera sensor, or the like. That is, the distance sensor 243 may include a transmitter and a receiver, and may output light or sound waves at a transmitter. The output light or sound wave can be reflected or refracted if there is an object. Reflected or refracted light or sound waves may be input to the receiver of the distance sensor 243. The distance sensor 243 can sense the distance to the object using the speed and time of light or sound waves. On the other hand, the camera sensor may mean a general camera. The camera sensor can detect the distance to the object by focusing the object and using the focal distance.

The first and second cameras 221a and 221b can take an object. 2, the first camera 221a and the second camera 221b are arranged in the left end corner area and the right end corner area, respectively. However, the first and second cameras 221a and 221b are arranged in different areas As shown in FIG. In addition, the mobile terminal 200 including the transparent display unit may include one camera or three or more cameras. The first and second cameras 221a and 221b and the distance sensor 243 shown in Fig. 2 may equally be included in the mobile terminal 100 shown in Figs. 1B to 1C.

Meanwhile, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly grasps and uses. These wearable devices include smart watch, smart glass, and head mounted display (HMD). Hereinafter, examples of a mobile terminal extended to a wearable device will be described.

The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device. For example, when a telephone is received in the mobile terminal 100, it is possible to perform a telephone conversation via the wearable device or to confirm the received message via the wearable device when a message is received in the mobile terminal 100 .

3 is a perspective view showing an example of a watch-type mobile terminal 300 according to another embodiment of the present invention.

3, the watch-type mobile terminal 300 includes a main body 301 having a display portion 351 and a band 302 connected to the main body 301 and configured to be worn on the wrist. In general, the mobile terminal 300 may include features of the mobile terminal 100 of Figures 1A-1C or similar features.

The main body 301 includes a case that forms an appearance. As shown, the case may include a first case 301a and a second case 301b that provide an internal space for accommodating various electronic components. However, the present invention is not limited to this, and one case may be configured to provide the internal space, so that a mobile terminal 300 of a unibody may be realized.

The watch-type mobile terminal 300 is configured to allow wireless communication, and the main body 301 may be provided with an antenna for the wireless communication. On the other hand, the antenna can expand its performance by using a case. For example, a case including a conductive material may be configured to electrically connect with the antenna to extend the ground or radiating area.

A display unit 351 is disposed on a front surface of the main body 301 to output information, and a touch sensor is provided on the display unit 351 to implement a touch screen. The window 351a of the display unit 351 may be mounted on the first case 301a to form a front surface of the terminal body together with the first case 301a.

The main body 301 may include an acoustic output unit 352, a camera 321, a microphone 322, a user input unit 323, a distance sensor 343, and the like. When the display unit 351 is implemented as a touch screen, the display unit 351 may function as a user input unit 323, so that the main body 301 may not have a separate key.

The band 302 is worn on the wrist so as to surround the wrist and can be formed of a flexible material for easy wearing. As an example, the band 302 may be formed of leather, rubber, silicone, synthetic resin, or the like. In addition, the band 302 is detachably attached to the main body 301, and can be configured to be replaceable with various types of bands according to the user's preference.

On the other hand, the band 302 can be used to extend the performance of the antenna. For example, the band may include a ground extension (not shown) that is electrically connected to the antenna and extends the ground region.

The band 302 may be provided with a fastener 302a. The fastener 302a may be embodied by a buckle, a snap-fit hook structure, or a velcro (trademark), and may include a stretchable section or material . In this drawing, an example in which the fastener 302a is embodied as a buckle is shown.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

FIG. 4 is a view for explaining an embodiment for adjusting the angle of view of the image to be photographed according to the distance from the user.

Referring to FIG. 4, a mobile terminal 200 including a transparent display unit and an image angle of view are shown. The image angle of view may be associated with the zoom function of the camera. For example, a camera can shoot a relatively small object when the angle of view is narrowed, but a detailed image of the object can be taken at the same resolution. On the contrary, a camera can shoot relatively many objects when the angle of view is widened, but a simple image of the object can be taken at the same resolution.

The user can see through the object on the opposite side of the mobile terminal 200 through the transparent display unit. Since the width of the transparent display unit of the mobile terminal 200 is constant, the user 11a located close to the mobile terminal 200 can see an object in a relatively wide range 51a. The user 11b located far away from the mobile terminal 200 can see an object in a relatively narrow range 51b. The mobile terminal 200 including the transparent display unit in the above-described manner can determine the angle of view of the photographed image.

In one embodiment, the mobile terminal 200 may include a distance sensor toward a first direction in which the user is located. The distance sensor can measure the distance from the user. The mobile terminal 200 may include information on a reference angle of view at a reference distance. The mobile terminal 200 may include the rate of change of the angle of view as the user approaches the reference distance. Likewise, the mobile terminal 200 may include rate of change information of the angle of view as the user moves away from the reference distance. If the rate of change of the angle of view is linear, the rate of change information of the angle of view as the user approaches the reference distance and the rate of change of the angle of view of the angle of view away from the reference distance may include a constant slope.

That is, the mobile terminal 200 measures the distance between the mobile terminal 200 and the user using the sensing unit, sets the angle of view of the image to be photographed wider according to a predetermined ratio as the distance from the user is measured , And as the distance increases, the image angle of the image to be photographed can be set to be narrower according to the predetermined ratio.

In the case of a general mobile terminal, a preview screen is displayed using a display unit because an object can not be seen through. However, the mobile terminal 200 including the transparent display unit may not display the preview image because the user can see the object through the transparent display unit. When the mobile terminal 200 including the transparent display unit does not display the preview image, battery consumption according to the preview image can be reduced. In addition, there is an advantage that the reaction speed of the camera can be increased.

On the other hand, the mobile terminal 200 including the transparent display unit does not display the preview image but determines the image angle of view based on the distance from the user, so that the user can not know the exact image to be photographed. Accordingly, the mobile terminal 200 including the transparent display unit can display the angle-of-view frame of the image to be photographed.

For example, the landscape displayed through the transparent display unit may be a mountain, a tree, or the like as shown in Fig. When the user 11a is positioned near the mobile terminal 200, the mobile terminal 200 can display the first angle-of-view frame 51a corresponding to the image to be photographed. When the user 11b is located at a position distant from the mobile terminal 200, the mobile terminal 200 can display the second angle of view frame 51b corresponding to the image to be photographed. As the user moves, the mobile terminal 200 can detect a distance to the user and display a proper angle-of-view frame on the transparent display unit. The mobile terminal 200 can take an image of the angle of view range indicated in the frame. The adjustment of the angle of view of the image to be photographed described in FIG. 4 can also be applied to a general mobile terminal.

5 is a view for explaining another embodiment for adjusting the angle of view of the image to be photographed according to the distance from the user.

Referring to FIG. 5 (a), a general mobile terminal 100 is shown. The camera 121 can shoot an object. The user 11a may be located relatively close to the mobile terminal 100. [ The distance sensor 143 can sense the distance from the user. As described with reference to FIG. 4, the mobile terminal 100 can set a wider angle of view of the image to be photographed according to a predetermined ratio as the distance from the user is detected.

That is, when the mobile terminal 100 determines that the user 11a is relatively located, it can set a relatively wide angle of view. In one embodiment, the mobile terminal 100, which captures an object of ABC, may display an image of ABC on the display unit 151.

Referring to Fig. 5 (b), a user 11b located at a relatively large distance is shown. The mobile terminal 100 can narrow the angle of view of the image to be photographed according to a preset ratio as the distance from the detected user increases.

That is, when the mobile terminal 100 determines that the user 11b is located relatively far away, the mobile terminal 100 can set a relatively narrow angle of view. In one embodiment, the mobile terminal 100, which captures an object of ABC, may display an image of B on the display unit 151.

The general mobile terminal 100 of FIG. 5 has only a difference in transparency between the mobile terminal 200 including the transparent display unit illustrated in FIG. 4 and the display unit, and the overall operation method may be similar.

Up to now, the process of setting the angle of view of the image related to the camera preview and shooting has been described. However, the above-described method can be similarly applied to the magnification control of the display screen.

6 is a view for explaining an embodiment for adjusting an image magnification to be displayed according to a distance from a user.

6 (a), a user 11a wearing a watch-type mobile terminal 300 is shown. A display unit 351 of the watch-type mobile terminal 300 displays contents. The screen 53a displayed on the display unit 351 is shown separately.

The user 11a may be located close to the watch-type mobile terminal 300. [ The watch-type mobile terminal 300 can sense the distance from the user. For example, the watch-type mobile terminal 300 can sense the distance to the user based on the user's eyes. Alternatively, the distance to the user may be sensed based on an arbitrary position of the user's body. 4, the watch-type mobile terminal 300 can adjust the screen magnification displayed on the display unit 351 in proportion to the distance from the user. In one embodiment, the watch-type mobile terminal 300 may zoom-out and display an image to be displayed according to a predetermined ratio as the distance from the detected user approaches.

As shown in FIG. 6 (a), the watch-type mobile terminal 300 can display a screen of 'ABC'. The distance from the user detected by the watch-type mobile terminal 300 may be relatively short. The watch-type mobile terminal 300 can zoom out the display screen 53a in proportion to the distance from the user. Therefore, the watch-type mobile terminal 300 can display 'ABC'.

Referring to FIG. 6 (b), a zoon-in display screen 53b is shown. In one embodiment, the watch-type mobile terminal 300 may zoom-in and display an image to be displayed according to a preset ratio as the distance from the detected user increases.

The user 11b may be detached from the mobile terminal 300. [ The mobile terminal 300 can detect that the distance from the user is far. In this case, the distance from the user sensed by the mobile terminal 300 may be relatively long. The watch-type mobile terminal 300 can zoom in on the display screen 53a in proportion to the distance from the user. Accordingly, the mobile terminal 300 can display only 'B' in 'ABC'.

In FIG. 6, an embodiment has been described in which the screen is displayed by zooming-out as the mobile terminal 300 approaches the user, and is displayed by zooming-in as the user moves further away from the user. However, zoom-in and zoom-out of the screen may vary depending on the setting. For example, the mobile terminal 300 zooms in and displays an image to be displayed according to a predetermined ratio as the distance from the user approaches, and zooms out the image to be displayed as the distance from the user increases, You may.

Meanwhile, the mobile terminal 100 may include a plurality of cameras. An embodiment of the mobile terminal 100 including a plurality of cameras will be described below.

Fig. 7 is a view for explaining an embodiment of shooting an object with a camera in a direction corresponding to an eye out of two eyes of a user.

The distance sensor 143 may be disposed on the mobile terminal 100 in a first direction in which the user is located. A plurality of cameras may be disposed in a second direction opposite to the first direction. For example, the plurality of cameras may be disposed continuously on one side of the mobile terminal. Alternatively, the plurality of cameras may be disposed in the right corner area and the left corner area. In Fig. 7, the first and second cameras 121a and 121b are arranged in the right and left corner areas.

Meanwhile, the distance sensor 143 may be implemented by at least one of a laser type sensor, an ultrasonic type sensor, an infrared type sensor, and a camera sensor. The camera sensor can be the same as a normal camera. That is, the camera sensor can focus on the user's image and detect the distance to the user based on the focal distance when the camera is in focus. Further, the camera sensor can photograph the user's two eyes 13a and 13b. The mobile terminal 100 may analyze the images of the two eyes of the photographed user to determine whether the two eyes 13a and 13b of the user are floating or wound.

When it is determined that only the left eye 13a of the two eyes of the photographed user is moving, the mobile terminal 100 can take an object with the camera 121a located at the leftmost of the plurality of cameras. When the mobile terminal 100 determines that only the right eye 13b of the two eyes of the photographed user is floating, the mobile terminal 100 can shoot an object with the camera 121b located at the rightmost of the plurality of cameras. If the mobile terminal 100 determines that both eyes of the two eyes of the photographed user are both floating, the mobile terminal 100 can photograph an object with the plurality of cameras 121a and 121b. Or, if it is judged that both eyes are open, an object can be photographed with two cameras.

When the mobile terminal 100 photographs an object with the left camera 121a, the first image 55a can be photographed. When the mobile terminal 100 photographs an object with the right camera 121b, the second image 55b can be photographed. When the mobile terminal 100 photographs an object with the left and right cameras 121a and 121b, both the first and second images 55a and 55b can be photographed. The first image 55a and the second image 55b have a parallax with respect to each other. Therefore, a 3D image can be generated by combining two images with time lag. That is, the mobile terminal 100 can generate a 3D image when a plurality of images are captured with a plurality of cameras to obtain a plurality of images having a time difference.

Although the general mobile terminal 100 is described in FIG. 7, the mobile terminal 200 including the transparent display unit may be similarly applied. On the other hand, the mobile terminal 100 can adjust the angle of view of the image to be photographed or the magnification of the image to be displayed according to the distance of the user. However, even if the desired angle of view or magnification is matched, the desired angle of view or magnification may vary due to slight movement of the user or the mobile terminal 100. [ In Fig. 8, a method of fixing the set angle of view or magnification will be described.

8 is a view for explaining an embodiment for fixing a set angle of view or magnification.

8 (a), the camera 121 of the mobile terminal 100 photographs an object, and the user 11a is a certain distance from the mobile terminal 100. FIG. The distance sensor 143 of the mobile terminal 100 may sense the distance to the user. The mobile terminal 100 determines that the distance from the user is relatively close to the user, and can set the angle of view of the image to be photographed wider. The image of the object to be photographed can be previewed on the display unit 151 of the mobile terminal 100 as shown in Fig. 8 (a) because the angle of view of the image to be photographed is set wide. The user can input a touch gesture for fixing the angle of view set on the display unit 151 of the mobile terminal 100. [ For example, a touch gesture that fixes a set angle of view may be one of a tab gesture, a sweep gesture, or a grip gesture. Alternatively, the mobile terminal 100 may fix the set angle of view only when the user 11a maintains the tap gesture for a certain period of time.

In FIG. 8 (a), the touch gesture for fixing the set angle of view is the tap gesture 21. The mobile terminal 100 can maintain the set angle of view by maintaining the tap gesture 21 state. Alternatively, the mobile terminal 100 may be operated in such a manner that the set angle is fixed by tapping once using the toggle function, and is unlocked by tapping again.

Fig. 8 (b) shows a view in which the set angle of view is fixed. As shown in FIG. 8 (b), the mobile terminal 100 can fix the angle of view of the image set in FIG. 8 (a). Therefore, even if the user 11b moves away from the mobile terminal 100, the mobile terminal 100 can maintain the angle of view of the set image.

8 illustrates an embodiment in which the angle of view of an image to be photographed is fixed, but the present invention can be similarly applied to a case of fixing a magnification of an image to be displayed.

Various embodiments have been described in which the angle of view of an image to be photographed by the mobile terminal 100 and the magnification of an image to be displayed are adjusted. A flow chart of the control method of the mobile terminal will be described below.

9 is a flowchart of a method of controlling a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 9, the mobile terminal can sense a distance to a user using a sensing unit disposed in a first direction in which a user is located (S910). The sensing unit may be realized by a sensor such as a laser type sensor, an ultrasonic type sensor, an infrared type sensor, a camera sensor, or the like. In particular, when the camera is implemented as a camera sensor, the mobile terminal can photograph two eyes of the user and detect the eyes of the two eyes. The mobile terminal can photograph an object with a camera in a direction corresponding to the detected bounced eye. In addition, if the mobile terminal detects that both eyes of the user are sensed, the mobile terminal may photograph an object with a plurality of cameras and generate a 3D image using a plurality of photographed images.

The mobile terminal can adjust the angle of view of the image to be captured or the magnification of the image to be displayed based on the distance from the detected user (S920). As described above, the angle of view of the image may be set wider according to a predetermined ratio as the distance from the user is detected, and may be set narrower as the distance increases. The magnification of the image can be displayed by zooming out the image to be displayed according to a preset ratio as the distance from the detected user approaches, and zooming in as the distance increases.

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.
