For example, the holography module 156 is disposed to overlap with the display unit 151 so that the holography image 156 is independently when the power of the display unit 151 is cut off together with visual information output from the display unit 151. ') Can be configured to output. The holography module 156 may be mounted on a bezel portion formed to surround the display unit 151.

In addition, as illustrated in FIG. 4B, the holography module 156 may be disposed on the rear side of the mobile terminal 100 to output the holographic image 156 ′ in a predetermined space on the rear side.

The position where the holography module 156 is mounted and the space where the holographic image 156 'is output are not limited to the above examples. The holography module 156 may be configured to be rotatable or pop-up, or may be detachably installed on the terminal body as a separate device. The holographic image 156 ′ may be output in a space irrespective of the installation direction of the holography module 156 through tilting, a separate reflection structure, and the like.

The holographic image 156 ′ that may be implemented through the holography module 156 may include both a 2D (2D) planar image and a 3D (3D) stereoscopic image.

The planar imaging method is a monoscopic method of providing the same image in both eyes, and arranges a polyhedron generated by one or more points, lines, planes, or a combination thereof in a virtual three-dimensional space, and views the polyhedron from a specific viewpoint. It is a method to display an image.

Next, the three-dimensional image method is a method of providing different images to both eyes (stereo scopic), a method using the principle that humans feel a three-dimensional feeling when viewing the object with the naked eye. That is, two eyes of a person see different plane images when viewing the same object by the distance between them. These different planar images are transmitted to the brain through the retina, and the brain fuses them to feel the depth and reality of the stereoscopic image. Therefore, although there is a slight difference for each person, the binocular disparity due to the distance between the two eyes makes a sense of three-dimensional feeling, and the method of displaying the image using the binocular disparity.

The holographic image 156 ′ generated by the holography module 156 to be described later may include both the planar image and the stereoscopic image. Hereinafter, for the sake of convenience of description, the planar image method may include the case of the stereoscopic image method.

Hereinafter, a method of expressing a holographic image 156 'applicable to embodiments of the present invention and a structure for implementing the same will be described in detail.

The image output through the display unit 151 records only the distribution of the light and dark sides of the object, whereas the holographic image 156 'is an image that simultaneously accumulates and reproduces all information, ie, amplitude and phase, of a light wave. Can be understood.

5A and 5B are conceptual diagrams for explaining the principle of holography.

Referring to FIG. 5A, coherent light from laser light source 201 is split into two through splitter 202.

One of these rays illuminates the subject 207, and light diffused from the surface of the subject 207 reaches the holographic photosensitive material 205. Hereinafter, this ray is called an object wave. Mirrors 203 and 204 can be used to divert the beam.

The other ray is redirected to the mirror 208 and diffuses through the lens 206 to directly reach the holographic photosensitive material 205. Hereinafter, this light beam is called a reference wave.

The object wave and the reference wave interfere with each other on the holographic photosensitive material 205 to produce about 500 to 1,500 very delicate and complicated interference patterns. Holographic storage media recording such interference fringes are called holograms.

Subsequently, when a light beam such as a reference wave generated as shown in FIG. 5B, that is, a reproducing wave is projected onto the holographic photosensitive material 205, an interference fringe acts as a diffraction grating so that light is emitted at a position different from the direction in which the reference wave is incident. Diffraction, the diffracted light is collected and formed like the light generated by the first object to project the holographic image 209. That is, the first object light may be reproduced through the hologram to be represented as the holographic image 209.

At this time, when looking inside the reproduced wavefront, the first object is visible, but it looks as if the object is inside. As you move the viewing point, the position of the object changes, making it look as if you are viewing a three-dimensional image. In addition, since the wavefront of the original object is reproduced, it can also interfere with the wavefront coming from a very deformed object.

The representation of the holographic image 209 may be classified into a transmissive holographic image representation and a reflective polographic image display scheme according to a reproduction scheme. 6A to 6C are conceptual diagrams for describing the transmissive holography method, and FIGS. 7A to 7C are conceptual views for explaining the reflective holography method.

Transmissive holographic image representation is a method to observe the image transmitted through the light from the back of the hologram in front of the hologram. In the transmission holographic image representation method, the object wave and the reference wave are exposed to the holographic photosensitive material in the same direction at the time of manufacture, and the generated holographic image is characterized by vivid and bright colors.

Referring to FIG. 6A, light emitted from the laser light source 301 passes through a spatial filter 302 and then spreads into a smooth spherical wave. One of the spherical waves divided into two light beams in the beam splitter 305 is illuminated on the object 308 to produce an object wave, and the other is illuminated on the holographic photosensitive material 307 as a reference wave. The object wave illuminated on the object 308 is also illuminated on the holographic photosensitive material 307. Mirrors 304, 306, 309 may be used to redirect the light beam.

At this time, the object wave and the reference wave illuminated on the holographic photosensitive material 307 interfere with each other to form an interference pattern, and the interference pattern is recorded on the holographic photosensitive material 307.

That is, as shown in FIG. 6B, the object wave and the reference wave are projected together on the same surface of the holographic photosensitive material 307 to generate an interference fringe.

Subsequently, as illustrated in FIG. 6C, when the same reproduction wave as the reference wave is projected onto the holographic photosensitive material 307, the object wave is transmitted in a direction opposite to the plane where the previous object wave and the reference wave are incident to generate a holographic image. .

Next, the reflective holographic image display method is manufactured so that the object wave and the reference wave are incident on the holographic photosensitive material in opposite directions to each other in such a manner that the image reflected by the light in front of the hologram can be observed in front of the hologram. The holographic image generated by the reflective holographic image display method is characterized by excellent stereoscopic effect.

Referring to FIG. 7A, light emitted from the laser light source 401 passes through a spatial filter 402 and then spreads into a smooth spherical wave as shown in FIG. 6A, and two beams are transmitted through a beam splitter 405. One is illuminated on the object 408 to produce an object wave, and the other is directly illuminated on the holographic photosensitive material (film) 407 to produce a reference wave. Mirrors 404, 406, 409 may be used to redirect the beam. However, unlike FIG. 6A, the reference wave and the object wave are illuminated with the holographic photosensitive material 407 at positions opposite to each other.

That is, as shown in FIG. 7B, the reference wave is projected onto the left side of the holographic photosensitive material 407, and the object wave is projected through the upper right side of the holographic photosensitive material 407. Subsequently, as illustrated in FIG. 7C, when the same reproduction wave as the reference wave is projected onto the holographic photosensitive material 407, the object wave is transmitted in the opposite direction to generate a holographic image.

In the present specification, the holographic photosensitive materials 307 and 407 are represented by a holographic storage medium provided in the holographic storage unit, and other components capable of generating a holographic image by projecting light onto the holographic photosensitive materials 307 and 407. Is represented by the holographic output.

For convenience of description, in the present specification, the holography storage unit and the holography output unit are described as being implemented together in the holography module 156. However, this is merely a mere example and may be included in the mobile terminal 100 in a separate configuration. .

Meanwhile, in relation to an embodiment of the present invention, the holographic image may be displayed according to the set holographic pattern. The holographic pattern means that the holographic image projected through the holography module 156 is changed to a preset pattern over time and provided to the user.

The holographic pattern may be variously set in the manner described below.

First, the holographic pattern may be set by changing the distance difference between the holographic output unit and the holographic image over time. According to the above configuration, since the holographic image projected through the holography module 156 can be moved up and down, a predetermined holography pattern can be set.

Next, the holographic pattern may be set by changing the shape of the holographic image projected by the holography module 156 over time. For example, the controller 180 may control the holographic image projected by the holography module 156 to have a circular shape at first, and then change the rectangular shape as time passes.

In addition, a method of moving or rotating the holographic image projected through the holography module 156 to the left or right may be applied. That is, the holographic pattern may be set by rotating the projected holographic image to move left and right, rotate, or move left and right according to time while maintaining the same distance difference between the holography module 156 and the holographic image.

In addition, the holographic pattern may be set by changing the color or size of the projected holographic image or adjusting the holographic image to blink. Furthermore, the holographic pattern may be set through projection brightness, refresh rate, illumination, vibration feedback, sound insertion, image insertion, repetitive projection, and the like.

In the above description, it is assumed that the holographic pattern is set by an individual factor, but the holographic pattern may be set by a plurality of elements. For example, the holographic pattern may be set to rotate and rotate the projected holographic image from side to side while changing the distance difference between the holographic module 156 and the holographic image over time.

In addition, although the description has been made on the assumption that the holographic pattern is set for the entire holographic image, this is merely an exemplary content, and the holographic pattern may be applied to only a part of the holographic image.

FIG. 8 is a conceptual view showing the first and second camera modules 121a and 121b of FIG. 2 taking a holographic image 156 ', and FIG. 9 is a first and third camera shown in FIGS. 2 and 3, respectively. A conceptual diagram showing that the modules 121a and 121c respectively photograph an area (user 500) other than the holographic image 156 'and the holographic image 156', and FIG. 10 is shown in the display unit 151 of FIG. 9 is a conceptual diagram illustrating that the captured image is divided and output.

8 to 10, the holographic module 156 is mounted on the terminal body to output the holographic image 156 ′ in a predetermined space. The predetermined space is determined by the arrangement of the holography module 156 and the attributes of the holographic image 156 '(eg, the size, direction, etc. of the holographic image 156'). The predetermined space may be limited to, for example, an inner space of a virtual sphere / semisphere having a specific radius around the holography module 156.

8 and 9 illustrate that the holography module 156 independently outputs the holographic image 156 'together with visual information output from the display unit 151 or when the display unit 151 is powered off. .

As described above, the holography module 156 includes a holography storage unit and a holography output unit.

The holographic storage unit includes a holographic storage medium for recording an interference pattern generated by the interference of the irradiated object wave and the reference wave with each other, and the holographic storage medium is a material that changes due to the action of light, such as a photopolymer. It consists of.

The holographic output unit irradiates the holographic storage unit (specifically, the holographic storage medium) with the same reproduction wave as the reference wave, and the holographic image 156 'generated by diffraction of the interference pattern recorded on the holographic storage medium and diffraction. Output to a predetermined space.

The camera body 121 is mounted to the terminal body. The camera 121 photographs the holographic image 156 'and processes an image frame such as a still image or a moving image obtained by the image sensor. The processed image frame may be displayed on the display unit 151, stored in the memory 160, or transmitted to the outside through the wireless communication unit 110.

In this figure, the first camera module 121a and the second camera module 121b are respectively installed on the front surface of the terminal body, and the third camera module 121c is mounted on the rear surface of the terminal body.

The first to third camera modules 121a, 121b, and 121c are disposed to face the predetermined space to capture the holographic image 156 ′. The first to third camera modules 121a, 121b and 121c may be configured to face the predetermined space through sliding, tilting, rotation, or the like.

The angles toward the predetermined spaces of the first to third camera modules 121a, 121b and 121c may be formed to be adjustable. For example, in the automatic mode, the controller 180 may recognize and analyze the holographic image 156 'to find an optimal angle and automatically adjust the angle. Meanwhile, in the manual mode, the holographic image 156 'viewed by the first to third camera modules 121a, 121b, and 121c is output to the display unit 151, and the user touches and drags the display unit 151. Alternatively, the angles of the first to third camera modules 121a, 121b, and 121c may be adjusted by directly adjusting a photographing range, angle, etc. of the holographic image 156 ′ through the user input unit 130.

The first to third camera modules 121a, 121b and 121c may be configured to focus on the predetermined space, and as a result, a clearer image may be obtained. The controller 180 may automatically adjust the focus of the first to third camera modules 121a, 121b and 121c by recognizing and analyzing the holographic image 156 ′.

In addition, the controller 180 may be configured to correct the setting of the holographic output unit by analyzing the holographic images 156 ′ photographed by the first to third camera modules 121a, 121b and 121c. In theory, the holographic output unit should irradiate the holographic storage unit with the same reproduction wave as the reference wave incident on the holographic storage unit. In practice, however, it is difficult to accurately match the characteristics of the reproduction wave (incidence angle to the holographic storage medium, wavelength, etc.) irradiated from the holographic output unit based on metadata stored in the memory. Therefore, the controller 180 has a feedback system for finely adjusting the characteristics of the inputted reproduction wave by analyzing the holographic image 156 'which is the output.

In addition, the controller 180 may analyze the holographic images 156 'photographed by the first to third camera modules 121a, 121b, and 121c to adjust characteristics according to surrounding environmental conditions or personal preferences. For example, when it is necessary to implement a brighter holographic image 156 'due to dark surroundings, when the holographic image 156' is not clear or the color is similar to the surrounding background, it is difficult to recognize the edge. ), The controller 180 can automatically adjust the characteristics of the holographic image 156 '.

Referring to FIG. 3, the flash 123 may be disposed to face a predetermined space to illuminate the holographic image 156 ′. For example, the flash 123 may be disposed to face the predetermined space through sliding, tilting, and rotation. The first to third camera modules 121a, 121b, and 121c may receive a sufficient amount of light even in a dark place through the flash to capture a more clear holographic image 156 ′.

Referring to FIG. 8, the first and second camera modules 121a and 121b may be formed to independently photograph the holographic image 156 ', or may be combined to photograph the three-dimensional holographic image 156'. Can be. In order to capture the 3D holographic image 156 ′, the first and second camera modules 121a and 121b are spaced apart from each other by a predetermined distance. The first and second camera modules 121a and 121b photograph left and right eye images, respectively, and the controller 180 generates the 3D holographic image 156 'by combining the left and right eye images.

Referring to FIG. 9, the first and / or second camera modules 121a and 121b are configured to photograph the holographic image 156 ′, and the third camera module 121c may be the first and / or second camera module. 121a and 121b may be formed to photograph a portion excluding a predetermined space when capturing the holographic image 156 '. For example, the third camera module 121c may be configured to capture a state of the user 500 when the holographic image 156 'is output.

Referring to FIG. 10, the holographic image 156 ′ captured by the first and / or second camera modules 121a and 121b and the image of the user 500 captured by the third camera module 121c may be displayed in a display unit ( The output may be divided into 151. For example, the holographic image 156 'may be output to occupy most of the main surface of the display unit 151 (first region 151a), and the image of the user may be output to occupy a relatively small area. (Second region 151b). The arrangement of the second and second regions 151a and 151b and the output method of the photographed image, such as the area, may include a touch input through dragging and clamping, an operation through the user input unit 130, and an operation of the terminal body. It may be changed through tilting or the like.

According to the present invention having the above-described configuration, since the first to third camera modules 121a, 121b, and 121c are disposed to face the predetermined space, the mobile terminal 100 is configured to photograph the holographic image 156 '. More various user interfaces may be implemented using the photographed holographic image 156 ′.

Hereinafter, the holographic control system 700 in which the target device 600 communicates with the mobile terminal 100 to capture the holographic image 156 'will be described in more detail.

11 and 12, the mobile terminal 100 transmits a packet 710 including location information of the terminal body and attribute information of the holographic image 156 ′. For example, the location information of the terminal body may be WLAN Access Point Info including information such as AP MAC Address and AP Signal Strength. In addition, the attribute information of the holographic image 156 'includes information about the size, direction, brightness, projection time, distance, and the like of the holographic image 156'.

The wireless communication unit 610 is configured to receive the packet 710, and the photographing unit 620 is formed to photograph the holographic image 156 ′ using the packet 710. At this time, the controller 630 is based on the packet 710, the position of the predetermined space in which the holographic image 156 'is output through the positioning technology using Wi-Fi, Cell-ID, GPS signal, NFC, etc. Obtain information.

A brief description of the Wi-Fi Positioning System (WPS) among the positioning techniques is based on the virtual AP DB information established through War-Driving and WLAN AP Info from the mobile terminal 100. Determine your location. That is, the WPS obtains location information on the mobile terminal 100 through triangulation based on the location of the AP of the Wi-Fi.

The photographing unit 620 may be moved toward the preset space through sliding, tilting, and rotation based on the acquired position information. In addition, the photographing unit 620 may be configured to focus on the predetermined space, thereby obtaining a clear image of the holographic image 156 '. Alternatively, the controller 630 may recognize the holographic image 156 ′ and automatically adjust the focus of the photographing unit 620.

The photographing unit 620 is formed to capture the holographic image 156 'by using the attribute information of the holographic image 156' in accordance with an optimal condition. For example, the zoom-in / zoom-out is performed according to the size of the holographic image 156 ', and the exposure degree is adjusted according to the holographic image 156' and the ambient brightness, and the shooting time is set according to the projection time. Can be.

The photographing unit 620 may be configured to photograph not only a predetermined space in which the holographic image 156 ′ is output, but also a portion except for the predetermined space. For example, the photographing unit 620 may be formed to photograph a surrounding background including the holographic image 156 ′ or the appearance of the user 500 looking at the holographic image 156 ′.

When the projection of the holographic image 156 'is completed, the photographing unit 620 ends the photographing, and the wireless communication unit 620 transmits the holographic image 156' photographed by the photographing unit 620 to the server 720. Is done. The server 720 may be, for example, a cloud server, an email server of a user account, a social network service server of a user account, or the like.

13 and 14 are conceptual views illustrating that the holography module 156 of FIG. 2 adjusts the projection direction of the holographic image 156 'based on the relative position information 730 of the mobile terminal 100 and the target device 600. And flowchart.

13 and 14, the wireless communication unit 610 of the target device 600 receives relative position information 730 with the mobile terminal 100 based on the received packet 710 described above with reference to FIGS. 11 and 12. It is made to transmit to the mobile terminal 100. The relative location information 730 includes location information of the photographing unit 620 as well as location information of the target device 600.

The holography module 156 of the mobile terminal 100 is configured to adjust the projection direction of the holographic image 156 'based on the relative position information 730. That is, the holography module 156 adjusts the projection direction so that the holographic image 156 ′ is located within the photographing range of the photographing unit 620.

In this case, the flash 123 of the mobile terminal 100 may be disposed to face a predetermined space to illuminate the holographic image 156 ′. The flash 123 may also be formed to adjust the illumination direction based on the relative position information.

The controller 630 of the target device 600 may be configured to analyze the holographic image 156 ′ photographed by the photographing unit 620 to generate a corresponding operation command. For example, the controller 630 may be configured to detect a specific pattern of the holographic image 156 ′ to perform authentication for whether the user is a specific user or to execute a specific program such as a video or music.

Referring to FIG. 15, when a user outputs a holographic image 156 ′ related to music in a building in which an ubiquitous environment is established, which is an example of the target device 800, the controller 820 may output a signal from the sensor 810. The sensed holographic image 156 'is analyzed to allow music to flow out of the audio. This can be utilized for various control methods such as turning off the lights and calling an elevator.

After sensing, the control unit 820 is configured to open the door of the vehicle. At this time, the controller 820 checks whether the three-dimensional information represented by the holographic image 156 'is authenticated three-dimensional information before opening the door of the vehicle. That is, the holographic image 156 'may be used as an authentication means to replace the vehicle's key.

According to this, the three-dimensional information formed by the holographic image 156 'can dramatically increase the amount of information that can be recorded as compared to a barcode having information in only one direction and a QR code having information in both horizontal and vertical directions. Can be. In addition, the three-dimensional information can be used as a means for authentication because a myriad of possible combinations.

The holographic image 156 ′ used for authentication may be output through a separate authentication procedure (for example, a password input) through the mobile terminal 100. Alternatively, the target device 800 first performs an authentication operation with authentication modules such as SIM, UIM, USIM, etc. through communication with the mobile terminal 100, and then performs second authentication using the holographic image 156 '. It can be configured to perform.

It can be used as a means for building an (ubiquitous) environment.
