The components shown in Fig. 1 are not essential, so that a mobile terminal having more or fewer components can be implemented.

Hereinafter, the components 110 to 190 of the mobile terminal 100 will be described in order.

The wireless communication unit 110 may include one or more modules for enabling wireless communication between the mobile terminal 100 and the wireless communication system or between the mobile terminal 100 and the network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short distance communication module 114, and a location information module 115.

The broadcast receiving module 111 receives broadcast signals and broadcast related information from an external broadcast management server through a broadcast channel. Here, the broadcast-related information means information related to a broadcast channel, a broadcast program, or a broadcast service provider. The broadcast-related information can also be provided through a mobile communication network. In this case, the broadcast-related information may be received by the mobile communication module 112. The broadcast signal and the broadcast-related information received through the broadcast receiving module 111 may be stored in the memory 160.

The mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Such wireless signals may include various types of data depending on a voice call signal, a video call signal, a text message, or a multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and may be embedded in the mobile terminal 100 or externally. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

The short-range communication module 114 refers to a module for short-range communication. As a short range communication technology, Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and the like can be used.

The position information module 115 is a module for acquiring the position of the mobile terminal 100, and a representative example thereof is a Global Position System (GPS) module.

1, an A / V (Audio / Video) input unit 120 is for inputting an audio signal and a video signal, and may include a camera 121, a microphone 122, and the like. The camera 121 processes image frames such as still images and moving images obtained by the image sensor in the video communication mode or the photographing mode. The image frame processed by the camera 121 can be displayed on the display unit 151. [ The image frame may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ More than two cameras 121 may be provided depending on the use environment.

The microphone 122 processes the sound signal input from the outside in the communication mode, the recording mode, the voice selection mode, and the like as electrical voice data. The voice data processed by the microphone 122 in the communication mode can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated when an external sound signal is input.

The sensing unit 140 senses the current state of the mobile terminal 100 such as presence or absence of a user, the open / close state of the mobile terminal 100, position, orientation, acceleration, deceleration, And generates a sensing signal. For example, when the mobile terminal 100 is in the form of a slide phone, the sensing unit 140 may detect whether the slide phone is opened or closed. The sensing unit 140 may sense whether the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144. The sensing unit 140 may be configured as a three-dimensional sensor that detects the position of a moving object (hereinafter, referred to as a sensing target) existing in a three-dimensional space. Here, the object to be sensed may be, for example, a body part (finger) of the user, an accessory device, or the like.

The sensing unit 140 may include a touch sensor (not shown) for sensing a touch operation with respect to the display unit 151. The touch sensor may have the form of a touch film, a touch sheet, a touch pad, or the like. The touch sensor may be configured to convert a pressure applied to a specific portion of the display portion 151 or a change in capacitance generated at a specific portion of the display portion 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the touch pressure.

When the touch sensor and the display unit 151 have a mutual layer structure, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be referred to as a 'touch screen'.

If there is a touch input via the touch screen, corresponding signals are sent to a touch controller (not shown). The touch controller processes the signals transmitted from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched.

In the case where the touch screen is electrostatic, it can be configured to detect the proximity of the sensing object by a change of the electric field along the proximity of the sensing target. Such a touch screen may be classified as proximity sensor 141. [

The proximity sensor 141 refers to a sensor that detects the presence or absence of an object to be sensed without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high. 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.

The proximity sensor 141 may be displayed in the inner area of the mobile terminal 100 or in the vicinity of the touch screen, which is enclosed by the touch screen. The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) and the sensing surface, which uses a force of the electromagnetic field or infrared light, to apply a touch without mechanical contact. The proximity sensor 141 can recognize which portion of the stereoscopic image has been touched using the measured distance.

On the other hand, the proximity sensor 141 may be configured to sense a touch on the three-dimensional space using the proximity of the sensing object.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal 100 operates in the call mode, the display unit 151 displays a UI (User Interface) or a GUI (Graphic User Interface) related to the call. When the mobile terminal 100 operates in the video communication mode or the photographing mode, the display unit 151 displays the photographed image, the received image, the UI, the GUI, and the like.

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.

At least one display (or display element) included in the display unit 151 may be configured to be transparent or light transmissive so that the display can see the outside through it. This can be referred to as a transparent display. A typical example of such a transparent display is TOLED (Transparent OLED). The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 in the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. [ For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from each other or positioned integrally with one another, and may be located on different surfaces.

The display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image. Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen. It is an image that makes you feel the same as reality space.

3D stereoscopic images are implemented using binocular disparity. Here, the binocular parallax means a parallax caused by the position of two eyes at a distance of about 65 millimeters. When the two eyes see different two-dimensional images and the images are transmitted to the brain through the retina and fused, And sense of reality.

In this specification, the term "depth value" refers to an index indicating the difference in distance between pop-up windows included in a three-dimensional image. More specifically, if the pop-up window displayed by the display unit 151 appears to the user in two-dimensional form, the depth value of the pop-up window may be defined as "0 ". However, the depth value of the pop-up window that appears as a protruded shape outside the mobile terminal 100 with respect to the screen of the display unit 151 as a three-dimensional shape may be defined as a negative value. On the other hand, the depth value of a pop-up window that appears in the form of entering the mobile terminal 100 may be defined as a positive number. In addition, as the position of the pop-up window included in the outwardly projecting three-dimensional image is closer to the closer, the absolute value of the depth value of the pop-up window increases and the position of the pop- The depth value of the pop-up window increases.

Hereinafter, for convenience of explanation, the position where the pop-up window included in the three-dimensional image is displayed is expressed as' the depth value of the pop-up window is larger 'as the distance is closer, and as' the depth value of the pop-up window is smaller as the distance is longer.

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), a projection system (holographic system) can be applied. The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the autostereoscopic method include a parallax barrier method, a lenticular method, and an integral imaging method. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images are composed of left image (left eye image) and right image (right eye image). A method of implementing a three-dimensional stereoscopic image includes a top-down method of displaying a left image and a right image vertically 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 left-to-right (L-to-R) side-by-side method in which left and right images are displayed in left and right directions in one frame, a checker board in which pieces of left and right images are displayed in a tile form, An interlaced method in which left and right images are alternately displayed in units of columns or rows, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

As an example of a three-dimensional stereoscopic image, a three-dimensional thumbnail image can generate a left-image thumbnail and a right-image thumbnail from a left image and a right image of an original image frame, respectively, have. Generally, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this manner are displayed with the left and right distance difference on the screen by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

When the stereoscopic display unit and the touch sensor have a mutual layer structure or when a stereoscopic display unit and a three-dimensional sensor for sensing a touch operation are combined with each other, the stereoscopic display unit can also be used as a three-dimensional input device. Such a stereoscopic display unit can be referred to as a 'three-dimensional touch screen'.

The alarm unit 153 may output a signal for informing occurrence of an event in a form other than a video signal or an audio signal, for example, vibration. The display unit 151 and the audio output module 152 may be classified as a part of the alarm unit 153 because the video signal or the audio signal can also be output through the display unit 151 or the audio output module 152. [

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration.

Meanwhile, the mobile terminal 100 is evolving to display a three-dimensional image enabling depth perception or stereovision beyond the level of a two-dimensional image display. This enables the user to enjoy a more realistic user interface or contents through the three-dimensional image. However, since the conventional mobile terminal 100 has no editing function for the three-dimensional image, there is a limit in causing the user to have fun.

Hereinafter, a mobile terminal 100 and a control method thereof capable of improving the convenience of a user in editing a three-dimensional image will be described with reference to the accompanying drawings.

The mobile terminal 100 may include a display unit 151 (see FIG. 1), a sensing unit 140 (see FIG. 1), and a controller 180 (see FIG. 1). The display unit 151 may be configured to allow touch input.

Referring to FIG. 3, step S110 is performed in which the first image is displayed on the display unit 151 in a two-dimensional mode.

Next, the sensing unit 140 senses a control command for executing the editing mode (S120).

Specifically, the sensing unit 140 may sense a touch input to the display unit 151. Also, the sensing unit 140 can detect the type and direction of the sensed touch input. Here, the sensing unit 140 may sense a touch input for designating at least a partial area of the first image as a control command for executing the editing mode.

Specifically, the control unit 180 can designate at least a partial area of the first image based on the detected trajectory of the touch input. Also, the control unit 180 can designate at least a partial area of the first image based on at least one of the drag gesture and the multi-touch gesture for the first image. Here, the multi-touch gesture refers to a touch gesture that allows a touch pad or a touch screen to simultaneously recognize a plurality of touch points.

When at least a partial region of the first image is designated, the second image corresponding to the specified at least partial region may be displayed on the display unit 151 in a form different from the first image. For example, the second image may be displayed on the display unit 151 in a three-dimensional mode. Accordingly, the second image may be displayed to protrude from the mobile terminal 100 or enter the mobile terminal 100 based on the display unit 151.

Next, a step S140 is performed in which the second image displayed in the three-dimensional mode is set as the editing material of the editing mode.

Specifically, the control unit 180 may display a menu for editing the second image on the display unit 151. [ At this time, if the touch input is detected within the reference time for the menu, the control unit 180 can edit the second image based on the touch input. For example, the control unit 180 may control the graphic information of the second image based on the touch input to the menu. Here, the graphic information may include at least one of a size, a shape, and a 3D depth value of the second image. Also, the controller 180 may display the second image in another area of the first image based on the touch input to the menu. Accordingly, the user can edit the first image.

On the other hand, if the touch input is not detected within the reference time for the menu, the control unit 180 may cause the menu to disappear from the display unit 151. [

On the other hand, the control unit 180 can control the graphic information of the second image based on the touch input to the second image without displaying the menu for editing the second image on the display unit 151. [ Also, the controller 180 may display the second image in another area of the first image based on the touch input to the second image.

As described above, according to the present invention, when at least a partial area of an image displayed on the display unit 151 is designated, an image corresponding to at least a partial area is displayed in a three-dimensional mode, And can be set as an edit material of the edit mode. Accordingly, the user can easily edit the three-dimensional image, and can enjoy the three-dimensional image editing. As a result, the convenience of the user can be improved.
