Description

Portable Terminal {MOBILE TERMINAL}

The present invention relates to a portable terminal capable of capturing a three-dimensional horizontal 3D image or a vertical 3D image through the main body and viewing a horizontal 3D image or a vertical 3D image photographed through the main body.

Terminals may be divided into mobile / portable terminals and stationary terminals according to their mobility.

As the functions are diversified, for example, the portable terminal is implemented in the form of a multimedia player having complex functions such as taking a picture or a video, playing a music or a video file, playing a game, or receiving a broadcast. In order to support and increase the function of such a terminal, it may be considered to improve the structural part and / or the software part of the terminal.

Recently, 3D image photographing or display technology has been in the spotlight. Accordingly, there has been a search for a method of capturing 3D images or displaying 3D images having a three-dimensional effect in a portable terminal.

In general, the 3D image may be provided by combining a left eye image and a right eye image. Accordingly, two cameras are provided at spaced positions in order to capture the left eye image and the right eye image for the 3D image, and the left eye image and the right eye image are respectively independently photographed.

The two cameras for taking the left and right eye images are designed to take images in a horizontal state like the left eye and the right eye, and the display unit for displaying 3D images also provides the left and right eye images, respectively. .

However, in general, the display unit is different from each other in width and height, and in the case of a portable terminal, the user may rotate and view the display unit horizontally or vertically according to the type of the image displayed on the display unit.

When a vertical image is displayed while a horizontal image is displayed horizontally, a general display device rotates the display apparatus in a vertical direction to observe the vertical image in a vertical direction (vertical direction). Can be observed.

However, since the display device for displaying 3D images provides a three-dimensional effect by the principle of selectively observing the left eye image and the right eye image with the left eye and the right eye, the display device designed to enjoy the horizontal image in the horizontal direction is vertical even if the display device is rotated vertically. You cannot enjoy 3D-viewing images.

However, unlike a stationary TV, a portable terminal is assumed to be portable, and the frequency of viewing a vertical image such as a photograph increases.

Accordingly, there is a need for a main body capable of capturing a vertical image in 3D and at the same time viewing the image in 3D on the entire display unit of the portable terminal.

When the display unit 151 and a sensor for detecting a touch operation (hereinafter, referred to as a touch sensor) form a mutual layer structure (hereinafter referred to as a touch screen), the display unit 151 is an output device. It can also be used as an input device. The touch sensor may have, for example, a form of a touch film, a touch sheet, a touch pad, or the like. The touch sensor may be configured to convert a change in pressure applied to a specific portion of the display unit 151 or capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor may be configured to detect not only the position and area of the touch but also the pressure at the touch.

If 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can determine which area of the display unit 151 is touched.

The proximity sensor 141 may be disposed in an inner region of the portable terminal 100 surrounded by the touch screen or near the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. Proximity sensors have a longer life and higher utilization than touch sensors.

Examples of the proximity sensor include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the touch screen may be configured to detect proximity of the pointer by a change in an electric field according to the proximity of the pointer. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized without being in contact with the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching the pointer on the screen is called "contact touch." The position where the proximity touch is performed by the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in proximity proximity.

The proximity sensor detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). Information corresponding to the sensed proximity touch operation and proximity touch pattern may be output on the touch screen.

The sound output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying occurrence of an event of the portable terminal 100. Examples of events generated in the portable terminal 100 include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than a video signal or an audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152, so that they 151 and 152 may be classified as part of the alarm unit 153.

The haptic module 154 generates various tactile effects that a user can feel. Vibration is a representative example of the haptic effect generated by the haptic module 154. The intensity and pattern of vibration generated by the haptic module 154 can be controlled. For example, different vibrations may be synthesized and output or may be sequentially output. The haptic module 154, in addition to the vibration, the pin arrangement to move vertically with respect to the contact skin surface, the blowing force or suction force of the air through the injection or inlet, the grazing to the skin surface, the contact of the electrode (eletrode), the stimulation such as electrostatic force Various tactile effects can be produced, such as the effects of the heat-absorbing effect and the effect of reproducing a sense of cold using the elements capable of absorbing heat or heat.

As described above, the portable terminal 100 according to the present invention may include at least two cameras to capture a 3D image, and furthermore, the portable terminal 100 according to the present invention may display a 3D image. 151 may be provided.

First, with reference to FIG. 2, the principle of taking or displaying a 3D image is examined.

The 3D image that can be implemented on the display unit 151 of the portable terminal 100 according to the present invention can be largely classified into two categories. The criterion of this division is whether different images are provided to both eyes. First, the first 3D image category will be described.

The first category is a method in which the same image is provided in both eyes (monoscopic), which can be implemented by the general display unit 151. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, planes, or a combination thereof in a virtual three-dimensional space, and displays an image viewed from a specific viewpoint on the display unit 151. That's how. Therefore, the real of the 3D image may be referred to as a planar image.

The second category is a method in which different images are provided in both eyes (stereoscopic), and a method using the principle of feeling a three-dimensional feeling when a human sees an object with the naked eye. That is, two eyes of a person may see different plane images when viewing the same object by the distance between them. These different planar images are delivered to the brain through the retina, and the brain can fuse them to feel the depth and reality of the 3D image. Therefore, although there are some differences between people, binocular disparity due to the distance between the two eyes makes a sense of three-dimensional feeling, and such binocular disparity becomes the most important element of the second category. Such binocular disparity will be described in more detail with reference to FIG. 2.

2 is a conceptual diagram for explaining the principle of binocular disparity. In FIG. 2, it is assumed that the object O having a hexahedral shape as a subject is viewed with the naked eye in front of the eye level. In this case, the left eye planar image 420 in which only three surfaces of the upper surface, the front side, and the left side of the object O can be seen as the left eye. In addition, as the right eye, the right eye plane image 430 showing only three surfaces of the top, front, and right sides of the object O may be seen.

If the left eye plane image 420 is reached in the left eye and the right eye plane image 430 is reached in the right eye, even if the object is not actually an object in front of the eye, the person may feel as if the person actually sees the object O.

As a result, in order to implement the 3D image of the second category in the mobile terminal 100, the left and right eye images, which are seen at the same time with the same object, must be separated and reached through the display unit 151. will be. Next, with reference to Figure 3 will be described the three-dimensional depth by binocular parallax.

3 is a conceptual diagram for explaining a sense of distance and three-dimensional depth due to binocular parallax.

Referring to FIG. 3, when viewing the object O at a distance d1 through both eyes, the lateral gravity of the image coming into each eye becomes higher than when viewing the object O at a distance d2. The difference can also be large. Also, the degree of stereoscopic feeling that a person feels when viewing the object O at a distance d1 may be greater than when viewing the object O at a distance d2. That is, when a person sees an object through both eyes, the closer the object is, the larger the three-dimensional effect is felt, and the farther the object is, the less the three-dimensional effect is felt.

And, when observing one object (O) with both eyes of the human body, the distance between both eyes is fixed, but the distance between the camera for taking the left eye image and the camera for taking the right eye image in order to realize the 3D image For the same reason, as the distance between the two cameras increases, the stereoscopic feeling of the 3D image can be increased. As shown in FIG. 3, when the distance between both eyes is S2, the distance between both eyes is increased than when S1 is increased, thereby increasing stereoscopic feeling. Increasing the distance between both eyes is because there is an effect of reducing the distance between both eyes and the object (O). Therefore, when shooting to realize a 3D image, a condition for improving stereoscopic feeling is that if the distance between both eyes is fixed, the distance d between the object O or the distance s between both eyes is increased. It can be seen that.

This difference in three-dimensionality can be digitized to a 3D depth or 3D level. Hereinafter, in the present specification, a high three-dimensional depth of a nearby object is represented by a low three-dimensional depth and a low three-dimensional level, and a low three-dimensional sense of a remotely located object is represented by a high three-dimensional depth and a high three-dimensional level. The definition of the three-dimensional depth or three-dimensional level is relative, and the classification criteria and the direction of increase / decrease may be changed.

In the present specification, in order to distinguish the above two categories, for convenience, the 3D image of the first category is referred to as "2D stereoscopic image", and the 3D image of the second category is referred to as "3D stereoscopic image". Next, an implementation method of the 3D stereoscopic image will be described.

As described above, in order to implement a 3D stereoscopic image, the right eye image and the left eye image need to be divided and reached to both eyes. Various methods for this will be described below.

First, the parallax barrier method will be described. The parallax barrier method is a method of electronically driving a blocking device provided between a general display unit 151 and both eyes so as to control a light traveling direction so that different images may be received from both eyes. The structure of the display barrier type display unit 151 for displaying a 3D stereoscopic image adds a configuration in which a switch liquid crystal is combined with a general display device. By operating an optical parallax barrier using a switch liquid crystal, it is possible to control the direction of the light to be separated so that different light reaches the left and right eyes. Therefore, when a combined image of the right eye image and the left eye image is displayed on the display unit 151, there is a method in which the image corresponding to each eye is seen from the user's point of view as if it is displayed in three dimensions.

In addition, in order to realize a 3D stereoscopic image, a lens refraction method may be considered as a method of reaching the right eye by dividing the right eye image and the left eye image, respectively. The lens refraction method uses a lenticular screen provided between the display unit 151 and both eyes. The lens refractive method allows a different image to be received from both eyes by refracting the light traveling direction through the lenses on the lenticular screen. There is a lens refraction method.

In addition, there is a polarization method in which polarization directions are perpendicular to each other to provide different images in both eyes, or in the case of circular flat light, polarization directions are different from each other to provide different images in both eyes.

In addition, as a type of eyeglasses, the right eye image and the left eye image are alternately displayed through the display unit 151 at predetermined intervals, and the user's glasses close the shutter in the opposite direction when the image in the corresponding direction is displayed. To reach the eye in that direction. In other words, the active shutter system closes the shutter of the right eye while the left eye image is displayed so that the left eye image reaches only the left eye, and closes the shutter of the left eye during the time the right eye image is displayed. There is this.

In this manner, the 3D image may be displayed, and the portable terminal 100 according to the present invention may include a display unit 151 for displaying the 3D image in any of the above-described methods.

As described above, in order to implement a 3D image, a left eye image and a right eye image are required. Therefore, in order to photograph the 3D image, a camera for photographing the same subject or object at least two or more spaced positions must be provided.

In order to display a 3D stereoscopic image (still image and / or a moving image) through at least one of the above-described 3D stereoscopic image implementation methods, a left eye image and a right eye image need to be prepared in the portable terminal 100, respectively. . To this end, in the embodiments of the present invention, at least two cameras should be disposed in the portable terminal 100 at a predetermined distance from each other, and the same subject may be photographed to capture a left eye image and a right eye image for a 3D stereoscopic image. do.

The two or more cameras are arranged to be spaced apart from each other by a predetermined distance to generate a left eye image and a right eye image having binocular disparity described with reference to FIGS. 2 and 3 through respective cameras.

The left eye image and the right eye image may be combined to provide a 3D image having a three-dimensional effect.

As described above, a display device such as a TV for displaying a 3D image provides a three-dimensional effect based on a principle of selectively observing a left eye image and a right eye image with the left eye and the right eye. Even if it is rotated in the vertical direction, the vertical image cannot be viewed as a three-dimensional 3D image. The reason is that since the left and right eyes of the body are located in the horizontal direction, the left and right eyes should be supplied to the left and right eyes spaced apart in the horizontal direction, respectively. Even if the display device having a width larger than the height is rotated in the vertical direction, the left and right eyes of the horizontally spaced positions are not able to observe the left and right eye images and thus may not be able to feel a three-dimensional effect.

Accordingly, as a method for solving such technical problems, Korean Patent Office Registration No. 10-0647517 (cell structure parallax-barrier and stereoscopic image display apparatus using the same) and Registration No. 10-0935892 (stereoscopic display panel) The invention disclosed in (joining device for performing horizontal / vertical alignment).

According to the registered inventions, a parallax-barrier and a stereoscopic image display apparatus including the same according to the present invention produce a barrier for reproducing a stereoscopic image in a cell unit by using a liquid crystal panel, thereby forming a barrier according to the characteristics of the stereoscopic image. Not only makes it possible to switch in the horizontal / vertical direction, but also 2D / 3D. That is, it is possible to view the 3D image by rotating the same display unit 151 horizontally or vertically, or to selectively view a general 2D image or a 3D image having a three-dimensional effect on the same display unit 151. In addition, the parallax-barrier and the stereoscopic image display apparatus including the same according to the registered invention include a cell gap between the pixels arranged in the cell structure of the liquid crystal part, and the etching direction of the lower plate and the upper plate and the polarizing film unit. Since the brightness of the image may be improved by adjusting the polarization direction, the overall brightness of the 3D image may be improved.

In addition, the parallax-barrier according to the registered invention and a three-dimensional image display device including the same, viewing angle and viewing distance by rotating the R, G, B arranged in the horizontal direction by 90 degrees to view the three-dimensional image The parallax-barrier and the stereoscopic image display device including the same according to the registered invention may have a low production difficulty, thereby improving workability and reducing costs.

Accordingly, the portable terminal 100 according to the present invention may include a cell structure parallax-barrier disclosed in the registered invention and a display unit 151 using the same.

In particular, the portable terminal 100 according to the present invention is supposed to be portable and may have a high frequency of photographing and appreciating the image in the vertical direction as well as the horizontal direction. Accordingly, by employing the cell structure parallax-barrier disclosed in the registered invention and the display unit 151 using the same in the portable terminal 100 according to the present invention, the horizontal image is 3D in the display unit 151 in the horizontal direction. Or, the vertical image can be displayed in 3D in the vertical direction on the display unit 151 and can be viewed.

That is, since the barrier of the parallax-barrier provided in the upper part of the liquid crystal that alternately displays the left eye image and the right eye image can be changed in the horizontal direction or the vertical direction, even when the same display unit is disposed in the horizontal direction or in the vertical direction, By changing the direction of the parallax-barrier and the display direction of the split image, 3D display of the horizontal image and the vertical image is possible.

 The present invention relates to a portable terminal capable of capturing a three-dimensional horizontal 3D image or a vertical 3D image through the main body and viewing a horizontal 3D image or a vertical 3D image photographed through the main body.

Patent No. 10-0647517 (cell structure parallax-barrier and a stereoscopic image display device using the same) and Patent No. 10-0935892 (bonding for performing horizontal / vertical alignment of a display panel for a stereoscopic image) Detailed description of the device is omitted, and the description is replaced by quoting the above specification.

However, the present invention is not limited thereto and may be applied to various structures such as a slide type, a folder type, a swing type, a swivel type, and two or more bodies are coupled to be relatively movable. The slide type and folder type will be described later.

The portable terminal according to the present invention includes a main body 300 and a photographing unit 200.

The main body 300 of the portable terminal 100 includes a housing forming an appearance. In this embodiment, the housing constituting the main body 300 of the portable terminal 100 may be divided into a front housing 101 and a rear housing 102. Various electronic components may be embedded in the space formed between the front housing 101 and the rear housing 102. At least one intermediate housing may be further disposed between the front housing 101 and the rear housing 102.

The housings may be formed by injecting synthetic resin, or may be formed to have a metal material such as stainless steel (STS) or titanium (Ti).

The main body 300 of the portable terminal 100 mainly includes a display unit 151, an audio output unit 152, a user input unit 130 (131-1, 131-2), a microphone 122, and the like in the front housing 101. This can be arranged.

The display unit 151 occupies most of the main surface of the front housing 101. An audio output unit 151 may be provided in an area adjacent to one end of both ends of the longitudinal direction of the display unit 151, and the first camera 121 is rotatably disposed at one end of the display unit 151 and adjacent to the other end of the display unit 151. The first user input unit 131-1 and the microphone 122 may be disposed in the area. The second user input unit 132 and the interface 170 may be disposed on side surfaces of the front housing 101 and the rear housing 102.

The user input unit is manipulated to receive a command for controlling the operation of the portable terminal 100, and may be provided in a form including a plurality of operation units, and according to its function, the first user input unit 131-1 And the second user input unit 131-2.

The user input units 131-1 and 131-2 may be collectively referred to as a manipulating portion, and may be adopted in any manner as long as the user operates the tactile manner with a tactile feeling.

The contents input by the first or second user input units 131-1 and 131-2 may be variously set. For example, the first user input unit 131-1 receives a command such as start, end, scroll, and the like, and the second user input unit 131-2 adjusts the volume of the sound output from the sound output unit 152. A command such as switching to the touch recognition mode of the display unit 151 may be input.

In addition, an antenna 116 for receiving a broadcast signal may be additionally disposed on the side of the terminal body. The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

A power supply unit (not shown) for supplying power to the portable terminal may be mounted. The power supply unit may be built in the terminal body or may be configured to be directly detachable from the outside of the terminal body.

The rear housing 102 may further be equipped with a touch pad (not shown) for sensing a touch.

The present invention includes a main body 300 having a display unit 151 capable of displaying a 3D image, a first camera 121 photographing a left eye image, and a second camera 121 'photographing a right eye image. A control unit configured to control the display unit 200 to change the coupling angle to the main body, convert the image captured by the capture unit 200 into a 3D image, or display the 3D image on the display unit 151. In addition, the controller provides a portable terminal 100 for changing the display direction of the 3D image of the display unit 151 corresponding to the type of 3D image.

The portable terminal 100 according to the present invention is provided with a photographing unit 200 having a first camera 121 and a second camera 121 'for capturing a left eye image and a right eye image, respectively, to capture a 3D image. .

The first camera 121 and the second camera 121 ′ of the photographing unit 200 are mounted to be spaced apart at predetermined intervals. The reason why the photographing unit 200 includes the first camera 121 and the second camera 121 'is that each of the first camera 121 and the second camera 121' has a left eye image for a 3D image. This is to shoot the right eye image.

The first camera 121 and the second camera 121 ′ may be mounted to be spaced apart from the photographing part housing 210. In addition, in the present invention, the photographing unit 200 is coupled to the main body 300 having the display unit 151 capable of displaying a 3D image so that the coupling angle can be changed.

Specifically, the first camera 121 and the second camera 121 ′ of the photographing unit are mounted to be spaced apart from each other in the longitudinal direction of the photographing unit housing 210, and the hinge h of the photographing unit housing 210 is mounted. The longitudinal end and the body housing can be rotatably coupled.

That is, the hinge h rotatably coupling the main body and the photographing unit may be provided at one end of the side surface of the main body 300.

The reason why the photographing unit 200 is coupled to change the coupling angle is to distinguish the horizontal image for viewing the 3D image in the horizontal direction and the vertical image for viewing the vertical direction.

The hinge (h) rotatably coupling the main body 300 and the photographing unit 200 of the portable terminal 100, like the hinge for mounting a general radio antenna on the main body, a hinge that can be rotated and tilted at the same time In the case of employing (h), as shown in FIGS. 5A to 5D, the photographing unit 200 can be displaced in the horizontal (horizontal) or vertical (vertical) direction. At the same time, the photographing direction of the camera mounted on the photographing unit 200 may be converted to the display direction of the display unit 151 or the direction opposite to the display direction of the display unit 151.

The photographing unit 200 may be provided detachably. Here, the photographing unit 200 detachably provided may include the hinge h. That is, up to the portion including the hinge h may be configured to be included in the photographing unit 200.

The photographing unit 200 has a hinge h, and may be detachably inserted into any one side of the side of the main body.

The photographing unit may be electrically and physically connected to the portable terminal 100 through the interface unit 170.

The main body 300 may be rotatably coupled to the photographing unit 200 in a predetermined range by the hinge h. The predetermined range may include 90 degrees. This is to shoot a horizontal image and a vertical image.

In general, the image taken by the camera of the portable terminal 100 is displayed at the same time as the recording via the portable terminal 100. Therefore, when the photographing unit 200 and the portable terminal 100 have their combined angles changed, when photographing a 3D image, the display unit 151 displays a horizontal 3D image in the state shown in FIG. In the state shown in FIG. 4 (b), the vertical 3D image can be confirmed by the display unit 151 and the image can be taken simultaneously.

In the portable terminal 100 illustrated in FIGS. 4A and 4B, since the photographing direction of the photographing unit 200 and the display direction of the display unit 151 are the same direction, the photographer photographs himself. In other words, self-shooting can be gathered. Of course, the self-shooting mode may include a video call mode. That is, it may include a 3D video call mode.

However, in the state illustrated in FIG. 4C, the photographing unit 200 is rotated in the state illustrated in FIG. 4B, and the photographing direction of the photographing unit 200 and the display of the display unit 151 are displayed. The direction is rotated in the opposite direction.

That is, the photographing target is positioned in front of the photographer rather than the self-photographing.

Of course, in the state illustrated in FIG. 4C, when the photographing unit 200 is folded toward the main body 300, the display unit 151 captures an image captured at the same time as the photographer photographs a photographing target located in front of the main body 300. ) Can be enjoyed in 3D. A description relating to the photographing mode of the embodiment shown in FIG. 4 will be described with reference to FIG. 5.

5 illustrates a mode of use of the portable terminal 100 according to the present invention. Descriptions overlapping with those described with reference to FIG. 4 will be omitted.

In detail, FIG. 5 (a) shows a case of taking a self-image 3D on a horizontal image, FIG. 5 (b) shows a case of taking a self 3D image on a vertical image, and FIG. 5 (c) shows a case on a horizontal image. FIG. 5D illustrates a case where 3D imaging is performed, and FIG. 5D illustrates a self 3D imaging of a vertical image.

5 (a) and 5 (b) illustrate a self-shooting mode in which a photographer, etc., located on the display direction side of the image of the display unit 151 is photographed using the portable terminal 100, and FIG. 5 (c). FIG. 5 (d) illustrates a general shooting mode in which the portable terminal 100 is used to photograph a photographing target and the like positioned in a direction opposite to the display direction of the image of the display unit 151.

As described above, the portable terminal 100 illustrated in FIG. 5 includes a photographing unit 200 capable of adjusting a coupling angle with respect to the main body. The photographing unit 200 includes a first camera 121 and a second camera 121 ′ for capturing a left eye image and a right eye image for a 3D image. In general, when the user takes a 3D image using the portable terminal 100, the first camera 121 and the second camera 121 in the same direction as the arrangement direction of the left and right eyes of the body, for example, the horizontal direction. ') May be maintained in the direction corresponding to the left and right eyes of the body so that the photographing unit 200 is disposed.

That is, since the 3D image provides a three-dimensional effect due to the visual difference between the left eye and the right eye, the photographing unit 200 should be maintained in a direction corresponding to the position of the left eye and the right eye regardless of whether the image is horizontal or vertical. .

Therefore, the embodiment shown in FIG. 5 assumes a case in which the left and right eyes of the photographer maintain a horizontal position, and the photographing unit 200 also maintains a horizontal state corresponding to the arrangement of the left and right eyes. Assume In the case of displaying a long vertical image in 3D in the vertical direction, it is assumed that it is displayed using the entire area of the display unit 151. That is, in a state where the display unit 151 having different widths and heights is disposed in the horizontal direction, only a partial area of the display unit 151 may be displayed, but the entire display unit 151 is not assumed. It is assumed that a 3D vertical image is displayed in the area.

The use mode illustrated in FIG. 5A illustrates a case in which the user takes a self-image 3D of the landscape image. As shown in FIG. 5 (a), when it is determined that the photographer needs to photograph the surrounding person including the person or the surrounding background, the photographer may take a horizontal image. In addition, the display unit 151 may display the horizontal image in a 3D manner.

In addition, if the photographing subject is only the photographer, portrait photographing may be more suitable than landscape photographing. In this case, the photographing unit 200 maintains a horizontal state, and photographs by rotating the main body 300 of the main body 300 coupled to the photographing unit 200 so as to change the coupling angle in a vertical direction.

In addition, when the photographing target is an external object other than the photographer, the photographing direction of the photographing unit 200 is rotated in a direction opposite to the display direction of the display unit 151, as illustrated in FIG. 5 (c) or 5 (b). As can be taken.

When the subject to be photographed is the same as FIG. 5 (c), the display unit 151 and the photographing unit 200 may both shoot and view in a horizontally arranged state.

In addition, in the case where the photographing target is a vertical image suitable for FIG. 5 (d), both the display unit 151 and the photographing unit 200 may be photographed and viewed in a state in which they are arranged in the vertical direction.

The use examples illustrated in FIG. 5 assume that the image is captured by the photographing unit 200 and the image captured by the photographing unit 200 is simultaneously viewed through the display unit 151 of the portable terminal 100 in 3D. Shall be.

In general, the portable terminal 100 includes an internal or external memory 160 (see FIG. 1), and stores an image photographed by a camera.

Therefore, even when playing the stored image through the portable terminal 100, when viewing the horizontal image in the horizontal direction and the vertical image in the vertical direction, the user can all enjoy the three-dimensional 3D image desirable.

Therefore, in the case of the horizontal image through the user's selection or the image type discrimination process according to the type of the stored image, the display unit 151 displays the stored image so that a stereoscopic feeling can be sensed on the premise that the display unit 151 is viewed in the horizontal direction. If the display is a vertical image, the display unit 151 may display the stored image so that a stereoscopic feeling can be sensed under the assumption that the display unit 151 is viewed in the vertical direction.

However, it is not easy to distinguish whether the controller itself of the portable terminal 100 is a horizontal image or a vertical image based on the information included in the image taken by the camera.

However, if the image stored in the memory of the portable terminal 100 is an image captured by the portable terminal, it is possible to distinguish the type of the stored image as follows.

That is, in the exemplary embodiment illustrated in FIGS. 5A and 5C among the photographing modes illustrated in FIG. 5, the direction of the display unit 151 and the photographing unit 200 coincide in the horizontal direction. In this case, it is determined that the image is a horizontal image, and in the exemplary embodiment illustrated in FIGS. 5B and 5D, the direction of the display unit 151 and the photographing unit 200 are different from each other in the horizontal and vertical directions. Therefore, in this case it can be determined that the vertical image.

Therefore, the controller may determine whether the image photographed by the photographing unit is a horizontal image or a vertical image according to a coupling angle of the main body and the photographing unit when capturing an image of the photographing unit.

That is, as described above, the photographing unit 200 is assumed to maintain the horizontal state or the direction parallel to the left and right eyes of the photographer.

Thus, according to the photographing conditions of the captured image, it is possible to distinguish whether the horizontal image or the vertical image.

The controller may determine the 3D display direction of the display unit according to whether the image displayed on the display unit 151 of the main body is a horizontal image or a vertical image based on information determined by a shooting condition.

6 illustrates playback modes of reproducing an image stored in a portable terminal according to the present invention. In detail, the embodiment illustrated in FIG. 6 (a) illustrates a viewing mode in which the horizontal image is viewed in 3D in the horizontal direction, and FIG. 6 (b) illustrates the viewing mode in which the vertical image is viewed in 3D in the vertical direction. . In each listening mode, the photographing unit 200 does not need to be deployed, and thus the image stored in the folded state of the photographing unit 200 and the main body 300 can be viewed.

Accordingly, the horizontal image or the vertical image may be viewed in 3D without regard to the coupling angle or the deployment angle of the photographing unit 200 and the main body 300.

As such, whether the playback target image is a horizontal image or a vertical image may be determined by a coupling angle between the main body 300 and the capturing unit 200 when capturing the image. A menu may be provided for the user to select whether the image is a portrait image.

7 shows another embodiment of a portable terminal according to the present invention. More specifically, Figure 7 (a) is a front perspective view of the state in which the photographing unit 200 of the portable terminal according to the present invention folded in the main body 300, Figure 7 (b) is a photographing unit of the portable terminal according to the present invention (200) is a front perspective view of the state deployed in the main body 300, Figure 7 (c) is a photographing unit 200 is rotated in the state in which the shooting unit 200 of the portable terminal according to the present invention deployed in the main body Front perspective view of the state.

Unlike the embodiment illustrated in FIG. 4, the embodiment illustrated in FIG. 7 may be viewed as a portable terminal specialized for capturing a vertical image in 3D.

That is, the embodiment illustrated in FIG. 7A illustrates a state in which the photographing unit 200 is folded in the upper surface direction of the main body 300 of the portable terminal 100. Therefore, the self-photographer may photograph the photographer in the vertical direction, and the display unit 151 may display the photographed vertical image in 3D. That is, since 3D photographing is possible without deploying the photographing unit 200, it may be referred to as a portable terminal specialized for photographing vertical images. In the photographing mode illustrated in FIG. 7B, the photographing unit 200 is deployed in a horizontal direction to self-photograph the horizontal image, and FIG. 7C illustrates a case in which the horizontal image of the object in front is photographed. do.

In conclusion, the portable terminal illustrated in FIG. 4 does not need to deploy the photographing unit 200 when photographing a horizontal image, and the embodiment illustrated in FIG. 7 deploys the photographing unit 200 when photographing a vertical image. You do not have to do.

Therefore, the portable terminals illustrated in FIGS. 4 and 7 may be referred to as cases specialized in photographing a horizontal image and cases photographing a vertical image, respectively.

8 is a block diagram illustrating a control method of a portable terminal according to the present invention. In the embodiment illustrated in FIG. 8, the display unit 151 of the portable terminal may display an image captured by the photographing unit 200 or an image stored in a memory (S100). In this case, when the photographed image is a 3D image or a 3D image, if it is determined whether to display the image in 3D by setting or user input (S120) and if it is determined to display as a 2D image instead of the 3D image, The image displayed on the display unit 151 may be displayed in 2D (S200 ′).

In the step of determining whether to display the image in 3D (S120), when it is decided to display the image in 3D, it is necessary to determine whether the image to be displayed in 3D is a horizontal image or a vertical image.

As described above, since the display unit 151 of the portable terminal according to the present invention can display a 3D image in both the horizontal direction and the vertical direction, the horizontal image and the vertical image should be displayed separately.

Therefore, as described above, it may be determined whether the image captured or stored is a horizontal image or a vertical image according to the combined angle of the main body 300 and the photographing unit 200 in the process of recording the image, It may be determined whether the horizontal image or the vertical image by the user's selection or setting.

Therefore, when the display unit 151 determines to display an image in 3D (S120), and the image to be displayed is recognized as the horizontal image or is determined as the horizontal image by user input or setting (S140), the display unit In operation 151, the horizontal image is displayed in 3D on the premise that the displayed image is a horizontal image.

If it is recognized as a vertical image or determined as a vertical image by a user input or setting (S140), the display unit 151 displays the vertical image in 3D on the premise that the displayed image is a vertical image.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. .
