Pursuant to 35 U.S.C. §119, this application claims the benefit of Korean Application No. 10-2010-0140694, filed on Dec. 31, 2010, the contents of which is hereby incorporated by reference herein in its entirety.
1. Field of the Invention
This specification relates to a mobile terminal, and more particularly, to a mobile terminal capable of efficiently controlling a hologram image at the time of a video call, and a hologram controlling method thereof.
2. Background of the Invention
In general, a mobile terminal is configured to perform various functions. These various functions include video and voice call communications, still or moving images capturing using a camera, voice storing, music file reproducing through a speaker system, image or video displaying, etc. Some mobile terminals include additional functions such as playing games, and other mobile terminals are implemented as multimedia players. Moreover, recent mobile terminals are configured to allow a user to view video or television programs by receiving broadcasting or multicast signals.
Various attempts have been made to implement enhanced functions of the mobile terminal not only by structural improvements, but also by hardware or software improvements.
A touch function of the mobile terminal allows even a user having a difficulty in inputting buttons or keys to conveniently operate the mobile terminal, by using a touch screen. Recently, this touch function is considered as an important function of the mobile terminal, together with a User Interface (UI) as well as simple input. Accordingly, developing a suitable UI is required more.
A hologram is a three-dimensional photographic image created with using a principle of holography. According to this principle, light emitted from laser is divided into two. One is used to directly illuminate a screen, and another is used to illuminate an object to be viewed. Here, light used to directly illuminate a screen is called ‘reference beam’, and light used to illuminate an object to be viewed is called ‘object beam’. The object beam is reflected from a surface of an object. Accordingly, a phase difference (a distance from an object surface to a screen) is different according to an object surface.
The reference beam which has not been transformed interferes with the object beam, and an interference pattern is stored into a screen. Here, a film having the interference pattern stored therein is called a ‘hologram’. In order to reproduce the stored hologram, the reference beam used when recording has to be re-projected on the screen. Among light projected when reproducing, only light having the same oscillation frequency as that when recording is represented in three dimensions. Here, light having a different wavelength and a different phase is not represented in three dimensions.
Although concerns for the hologram are being increased, methods for controlling and utilizing the hologram have not been concretely disclosed. Especially, there have been performed no researches about all scenarios which may occur when the hologram is applied to a small electronic device such as a mobile terminal.
Therefore, an aspect of the detailed description is to provide a mobile terminal capable of effectively controlling each scenario which may occur when a hologram is applied thereto, and a hologram controlling method thereof.
Another aspect of the detailed description is to provide a mobile terminal capable of effectively moving and controlling a hologram image at the time of a video call, and a hologram controlling method thereof.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, a hologram controlling method of a mobile terminal includes displaying a hologram image, detecting an input with respect to the hologram image, and controlling the displayed hologram image based on the detected input.
The hologram image may include a two-dimensional hologram, a three-dimensional hologram and a cubic-type hologram.
The two-dimensional hologram may include an image converted from a pre-stored plane type image, a still image or a voice, and the three-dimensional hologram may include an image converted from a moving image.
The hologram image may be configured to have a background color automatically changed according to peripheral circumstances, and to have an emitting angle automatically changed according to shake so as to maintain a horizontal state.
An input of the hologram image may include an input through a management screen or a direct input, and the input may include a touch operation.
The hologram image may be displayed through one or more hologram output units, and may be moved between the hologram output units and between the hologram output unit and the management screen.
The hologram image may be moved, exchanged and copied between the hologram output units through a user's touches or communications and approaches between devices, and a viewing angle of the hologram image may be controlled through a personal protection setting.
A display size of the hologram image may be automatically controlled according to a user's distance, and an entire part or a specific part of the hologram image may be moved, enlarged and contracted.
The hologram image may include a hologram preview function displayed when capturing an image, or a hologram distance viewer of an area selected by a user on a map.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, a mobile terminal includes a hologram output unit configured to display a hologram image, a display unit configured to display contents selected by a user, and a controller configured to control the displayed hologram image based on an input with respect to the hologram image.
The hologram image may include a two-dimensional hologram, a three-dimensional hologram, and a cubic-type hologram. Especially, the hologram image may include a hologram preview function displayed when capturing an image, or a hologram distance viewer of an area selected by a user on a map.
The two-dimensional hologram may include an image converted from a pre-stored plane type image, a still image or a voice, and the three-dimensional hologram may include images converted from moving images.
The hologram output unit may be implemented as one or more hologram cameras, and may be installed at the same position or different positions.
The controller may automatically change the hologram image according to peripheral circumstances, and may automatically change an emitting angle according to shake so as to maintain a horizontal state of the hologram image.
Once a user selects specific contents on the display unit, the controller may check whether the selected contents support a hologram. If the selected contents support a hologram, the controller may display a hologram image through the hologram output unit. On the contrary, if the selected contents do not support a hologram, the controller may display the contents on the display unit.
An input of the hologram image may include an input through a management screen or a direct input, and the input may include a touch operation.
When the hologram output unit is implemented in plurality in number, the controller may control movements of a hologram image between the hologram output units and between the hologram output unit and the management screen.
The controller may control movements, exchanges and copying of a hologram image between the hologram output units through a user's touches or communications and approaches between devices, and may control a viewing angle of a hologram image through a personal protection setting.
The controller may automatically control a display size of a hologram image according to a user's distance, and may control movement, enlargement and contraction of an entire part or a specific part of the hologram image according to a user's touch input.
Further scope of applicability of the present application will become more apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from the detailed description.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments and together with the description serve to explain the principles of the invention.
In the drawings:
Description will now be given in detail of the exemplary embodiments, with reference to the accompanying drawings. For the sake of brief description with reference to the drawings, the same or equivalent components will be provided with the same reference numbers, and description thereof will not be repeated.
Hereinafter, a mobile terminal according to the present invention will be explained in more detail with reference to the attached drawings. The suffixes attached to components of the wireless speaker, such as ‘module’ and ‘unit or portion’ were used for facilitation of the detailed description of the present invention. Therefore, the suffixes do not have different meanings from each other.
A terminal may be implemented in various types. For instance, the terminal in the present description includes a mobile terminal such as a portable phone, a smart phone, a notebook computer, a digital broadcasting terminal, Personal Digital Assistants (PDA), Portable Multimedia Player (PMP), a navigation system, and a fixed terminal such as a digital TV, a desktop computer, etc. It is assumed that the terminal of the present invention is a mobile terminal. However, it will be obvious to those skilled in the art that the present invention may be also applicable to the fixed terminal, except for specific configurations for mobility.
For example, the wireless communication unit 110 includes a broadcast receiving module 111 that receives a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel.
In addition, the broadcast managing entity generally refers to a system which transmits a broadcast signal and/or broadcast associated information. Examples of broadcast associated information include information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).
In addition, the broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. The broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.
The broadcast receiving module 111 is also configured to receive broadcast signals transmitted from various types of broadcast systems. For example, such broadcasting systems include the digital multimedia broadcasting-terrestrial (DMB-T) system, the digital multimedia broadcasting-satellite (DMB-S) system, the digital video broadcast-handheld (DVB-H) system, the data broadcasting system known as media forward link only (MediaFLO®) and the integrated services digital broadcast-terrestrial (ISDB-T) system among others. Receiving multicast signals is also possible. Further, data received by the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.
The wireless communication unit 110 also includes a mobile communication module 112 that transmits/receives wireless signals to/from one or more network entities (e.g., base station, Node-B). Such signals may represent audio, video, multimedia, control signaling, and data, among others.
Also included is a wireless Internet module 113 that supports Internet access for the mobile terminal. The module 113 may be internally or externally coupled to the terminal. The wireless communication unit 110 also includes a short-range communication module 114 that facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.
A position-location module 115 is also included in the wireless communication unit 110 and identifies or otherwise obtains the location of the mobile terminal 100. The position-location module 115 may be implemented using global positioning system (GPS) components which cooperate with associated satellites, network components, and combinations thereof.
In addition, as shown in
Further, the microphone 122 receives an external audio signal while the portable device is in a particular mode, such as a phone call mode, recording mode and voice recognition mode. The received audio signal is then processed and converted into digital data. Also, the portable device, and in particular, the A/V input unit 120, includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal. In addition, data created by the A/V input unit 120 may be stored in the memory 160, utilized by an output unit 150, or transmitted via one or more modules of the communication unit 110. If desired, two or more microphones and/or cameras may be used.
The mobile terminal 100 also includes a user input unit 130 that generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel and a jog switch. A specific example is one in which the user input unit 130 is configured as a touchpad in cooperation with a touch screen display, which will be described in more detail below.
A sensing unit 140 is also included in the mobile terminal 100 and provides status measurements of various aspects of the mobile terminal 100. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100, etc.
As an example, when the mobile terminal 100 is a slide-type mobile terminal, the sensing unit 140 may sense whether a sliding portion of the mobile terminal 100 is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by a power supply 190, the presence or absence of a coupling or other connection between an interface unit 170 and an external device, etc.
Further, the interface unit 170 is often implemented to couple the mobile terminal 100 with external devices. Typical external devices include wired/wireless headphones, external chargers, power supplies, storage devices configured to store data (e.g., audio, video, pictures, etc.), earphones, and microphones, among others. In addition, the interface unit 170 may be configured using a wired/wireless data port, a card socket (e.g., for coupling to a memory card, a subscriber identity module (SIM) card, a user identity module (UIM) card, a removable user identity module (RUIM) card, etc.), audio input/output ports and video input/output ports.
The output unit 150 generally includes various components which support the output requirements of the mobile terminal 100. The mobile terminal 100 also includes a display 151 that visually displays information associated with the mobile terminal 100. For instance, if the mobile terminal 100 is operating in a phone call mode, the display 151 will generally provide a user interface or graphical user interface which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes.
Further, the display 151 also preferably includes a touch screen working in cooperation with an input device, such as a touchpad. This configuration permits the display 151 to function both as an output device and an input device. In addition, the display 151 may be implemented using display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display.
The mobile terminal 100 may also include one or more of such displays. An example of a two-display embodiment is one in which one display is configured as an internal display (viewable when the terminal is in an opened position) and a second display configured as an external display (viewable in both the open and closed positions).
In addition, the output unit 150 is further shown having an alarm 153, which is used to signal or otherwise identify the occurrence of a particular event associated with the mobile terminal 100. Alarm events include a call received, a message received and user input received. An example of such output includes the providing of tactile sensations (e.g., vibration) to a user. For instance, the alarm 153 may be configured to vibrate responsive to the mobile terminal 100 receiving a call or message.
As another example, a vibration is provided by the alarm 153 responsive to receiving user input at the mobile terminal 100, thus providing a tactile feedback mechanism. Further, the various outputs provided by the components of the output unit 150 may be separately performed, or such output may be performed using any combination of such components.
In addition, the memory 160 is used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 100. Examples of such data include program instructions for applications operating on the mobile terminal 100, call history, contact data, phonebook data, messages, pictures, video, etc.
Further, the memory 160 shown in
The terminal 100 also includes a controller 180 that typically controls the overall operations of the mobile terminal 100. For instance, the controller 180 performs the control and processing associated with voice calls, data communications, instant message communications, video calls, camera operations and recording operations. As shown in
The controller 180 may perform a pattern recognition process for recognizing a writing input or a drawing input on the touch screen, as a text and an image, respectively. And, the controller may convert plane-type contents, still images and moving images into hologram images.
The power supply unit 190 receives external power or internal power and supplies appropriate power required for operating respective elements and components under the control of the controller 180.
Processes described herein may be implemented in a computer-readable or its similar medium using, for example, software, hardware, or any combination thereof.
For hardware implementation, the processes may be implemented by using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, and electronic units designed to perform the functions described herein. In some cases, such processes may be implemented by the controller 180 itself.
For software implementation, the processes, such as procedures or functions, may be implemented together with separate software modules that allow performing of at least one function or operation. Software codes can be implemented by a software application (or program) written in any suitable programming language. The software codes may be stored in the memory 160 and executed by the controller 180.
The mobile terminal according to the present disclosure will be explained in more details with reference to
In addition, the mobile terminal 100 of
Hereinafter, the communication systems where the mobile terminal of the present invention is operable will be explained with reference to
Examples of such air interfaces utilized by the communication systems include, for example, frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), and universal mobile telecommunications system (UMTS), the long term evolution (LTE) of the UMTS, and the global system for mobile communications (GSM). By way of a non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types.
As shown in
Also, each base station 270 may include one or more sectors, each sector having an omnidirectional antenna or an antenna pointed in a particular direction radially away from the base station 270. Alternatively, each sector may include two antennas for diversity reception. In addition, each base station 270 may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz).
The intersection of a sector and frequency assignment may be referred to as a CDMA channel. The base stations 270 may also be referred to as base station transceiver subsystems (BTSs). In some instances, the term “base station” may be used to refer collectively to a BSC 275, and one or more base to stations 270. The base stations 270 may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station 270 may be referred to as cell sites.
As shown in
Further, during typical operation of the wireless communication system, the base stations 270 receive sets of reverse-link signals from various mobile terminals 100. The mobile terminals 100 engage in calls, messaging, and other communications. In addition, each reverse-link signal received by a given base station 270 is processed within that base station 270, and the resulting data is forwarded to an associated BSC 275. The BSC 275 provides call resource allocation and mobility management functionality including soft handoffs between the base stations 270. Further, the BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN interfaces with the MSC 280, and the MSC 280 interfaces with the BSCs 275. The BSCs 275 also control the base stations 270 to transmit sets of forward-link signals to the mobile terminals 100.
The present invention provides a method for controlling a hologram screen when projecting a hologram image with using a mobile terminal, and a method for moving a hologram image by touching a keypad of the mobile terminal.
The mobile terminal according to the present invention is provided with a function for displaying plane-type menus, texts, a still screen and each type of contents by converting into a two-dimensional (2D) or three-dimensional (3D) hologram. Also, the mobile terminal according to the present invention is provided with a function for converting a voice into a text, then converting the text into a 2D hologram, and then displaying the 2D hologram.
As shown in
The camera 121 serving as a hologram output unit is configured to perform a general capturing operation in a camera mode, and is configured to output downloaded hologram contents or hologram contents stored in the memory 160 in a hologram mode.
A hologram image output from the camera 121 may be changed by inputting a specific key.
As shown in
In the present invention, hologram displayable contents (programs or images) and hologram non-displayable contents are separately displayed on a hologram menu. For instance, hologram displayable contents are represented by displaying “H” on a circular icon, and hologram synthesizable contents are represented by displaying “H” on a triangular icon. Accordingly, a user may output a hologram image with respect to desired contents by checking the icons on the hologram menu.
As shown in
For instance, once a user commands a hologram output with respect to a message written on a message writing screen, or a specific message selected from a transmitting/receiving message list stored in the memory 160, the controller 180 converts the selected text-type message into a 2D hologram. Then, the controller 180 outputs the converted 2D hologram through the camera. In this case, the text image displayed in the form of a hologram may be a fixed type that the entire message is fixed, or a toggle type that lines move one by one in the unit of predetermined characters, or a type that a voice and a hologram are simultaneously reacted with each other according to a voice expression.
In the present invention, a user's voice as well as texts may be recognized, and the recognized voice may be displayed in the form of a hologram image.
Generally, a hologram image may be set though a hologram menu setting. More concretely, a user may select a type (refer to
As aforementioned, a size of a hologram image is controlled through a hologram menu. In a state that an initial size of a hologram image has been preset through the hologram menu, the preset initial size of the hologram image may be controlled according to a user's input. Alternatively, the preset initial size of the hologram image may be automatically controlled according to a user's distance.
This function is performed to prevent invasion of a user's privacy resulting from that a hologram image is easily exposed to another party.
Once a user approaches to a mobile terminal from which a hologram image is being emitted, the controller 180 detects the user's approach. Then, the controller 180 converts a current mode of the mobile terminal into a whispering mode, and automatically contracts a size of the hologram image. The controller 180 may detect the user by a well-known technique, especially, a face recognition technique. Alternatively, the controller 180 may decrease a size of the hologram image according to a user's approaching distance, and may convert a current mode of the mobile terminal into a whispering mode when the user has come near the mobile terminal by a predetermined distance.
In the present invention, a size of a hologram image may be controlled according to a size of a user's voice at a fixed position. More concretely, a size of a hologram image is controlled according to a size of a user's voice input at the same distance in an assumption that a user's voice input at the same distance has nearly the same size.
In the present invention, the controller 180 may control a display size of a hologram image with consideration of a user's approach and a voice size. Alternatively, the controller 180 may display a hologram image on a screen having a size preset by a user, through analysis of the user's voice substantially input.
Generally, a hologram image is displayed by emitting predetermined light. Accordingly, clarity (visibility) of the displayed hologram image is influenced by peripheral circumstances. In the present invention, a hologram image may be changed by peripheral circumstances such as peripheral luminance, brightness and a chroma. For instance, a color of a background light (reference beam) of a hologram image is changed according to peripheral luminance, brightness and a chroma.
In the present invention, a hologram image is emitted through the camera provided at one side of the mobile terminal. The camera is configured to perform a capturing operation in a general capturing mode, and to display predetermined contents by projecting object beam onto reference beam in a hologram mode.
In the present invention, one hologram camera is provided. However, the present invention is not limited to this. More concretely, two hologram cameras may be provided to simultaneously display different menus or contents. For instance, contents to be transmitted are projected through one hologram camera, and received contents are projected through another hologram camera. This may allow a user to simultaneously view different hologram images.
Referring to
Alternatively, both of the first and second hologram cameras 60 and 61 may be used to display only reception images or only transmission images.
A user may manipulate a hologram image through the management screen 50 of the mobile terminal with grasping the mobile terminal by using his or her one hand. As shown in
In the present invention, in a case that the mobile terminal severely shakes while a user performs a video call, the controller 180 detects the shaking to inform to another party. Here, shake of the mobile terminal may be detected by a gradient sensor or a gyro sensor, and so on. Especially, when the mobile terminal has shaken to have a capturing angle which exceeds a predetermined range, the controller 180 may automatically change an emitting angle of a hologram image captured by the hologram camera. This may allow a user's image to be normally captured to be transmitted to another party.
Generally, a hologram screen may have less restrictions in spatial utilizations than a general screen of a mobile terminal. Accordingly, a multi-tasking may be easily performed on the hologram screen. For instance, in a state that a hologram menu including a plurality of hologram images has been displayed, when a user selects two images in a multi-touching manner, the controller 180 displays a multi-view on a hologram screen. More concretely, the controller 180 divides the hologram screen into two parts, and displays one image on one screen and displays another image on another screen. Here, the selected images may be displayed from the left to the right, according to selected orders or priorities thereof.
Each hologram image may be individually selected by a user's touch, and the selected hologram image may be displayed on the hologram screen.
As aforementioned in
As shown in
In the present invention, when performing a video call by using a hologram image, a user's image may be transmitted to another party and another party's image may be displayed in the form of a hologram. Furthermore, data may be shared between the user and another party.
As shown in
While performing a holographic video call with another party, the user may display contents being displayed on the display unit 151 as a hologram image in a touching manner, or may display a hologram image on the display unit 151. For instance, as shown in
Once the user touches a corresponding hologram image during a hologram communication, or in a state contents on the screen are displayed as a hologram image, the controller 180 transmits the hologram image to another party as shown in
The present invention provides various control methods using a hologram image. Generally, when two or more hologram images are displayed in an overlapping manner, an interference may occur at an overlapped part between the hologram images. The present invention provides a function to control one hologram by another hologram with using an interference phenomenon occurring at an overlapped part between the hologram images.
As shown in
Referring to
Referring to
As shown in
In a state that two contents (e.g., faces) are displayed through two hologram cameras, a user may capture specific parts (e.g., noses) of hologram images, and then may move the captured parts to one side or may synthesize the captured parts in an exchanging manner. Here, a part to be captured may include a part of an image or a picture, or a specific word.
As shown in
As shown in
More concretely, when a user touches one hologram image and drags the touched hologram image to outside of a reference image, the hologram image may be copied onto another hologram image or may be moved to another hologram image. If one hologram image is moved to another hologram image, the hologram output unit having no hologram image is automatically turned off.
In a case that a plurality of mobile terminals are provided with two or more hologram output units, hologram images outputted from the hologram output units may be overlapped with one another, or may be copied or moved between the mobile terminals by using a communication device (e.g., Ad hoc).
Generally, a hologram image may be freely displayed on an open space. This may require a restriction function so as to prevent invasion of a user's privacy. As aforementioned, a display size of a hologram image is controlled according to a user's distance and a voice size for protection of a user's privacy.
The present invention is not limited to this, but may protect a user's privacy by controlling a display angle of a hologram image through a personal protection setting.
As shown in
There has been already disclosed a method for displaying an extended (wide) image (e.g., multi-vision) by dividing an image displayed on a screen of a mobile terminal into a predetermined ratio, and then by displaying the divided image onto another display device. This concept may be equally applied to a hologram. In order to generate an extended (wide) hologram image, data is shared between mobile terminals. In this state, if an image ratio is wirelessly adjusted, hologram images are displayed through a plurality of hologram output units. Then, a user may implement one extended (wide) hologram image (holography) by combining the displayed hologram images with each other.
The hologram distorting function is used to provide fun to a user by distorting a displayed hologram image, and may include a partial enlargement, a perspective, black and white, sepia, and so on. A type of the hologram distorting function may be selected by a user through a hologram menu.
For instance, the controller 180 may control a user to feel a texture of a hologram image through vibrations of the mobile terminal or electrical signals. Alternatively, the controller 180 may control a user to feel a texture of a hologram image through his or her sense organs stimulated by light and far infrared rays of the hologram image. Still alternatively, the controller 180 may control a user to feel a texture of a hologram image through a method of stimulating a sense of touch, the method using an ultrasonic wave radiation pressure. However, the present invention is not limited to this. More concretely, a user may move a specific object (a ball in case of a baseball game) directly or by using wind. Alternatively, the controller may provide a perspective to a displayed image object, thereby displaying the image object as if it was moving. Still alternatively, the controller may represent a texture of a hologram image by providing each piece having a different shape and a different movement, like a jigsaw puzzle game.
In the present invention, a hologram image is basically input through a user's touch using a finger. However, the present invention is not limited to this. More concretely, a hologram image may be input through an external input device.
As shown in
As shown in
A recent communication network may be provided with a small capacity of memory when transmitting or receiving a full 3D image or a hologram image. In order to solve the small capacity of memory, a transmission amount of data may be reduced by transmitting only movement information and background information. In a method for transmitting movement information, when a figure image is displayed, positions of joints are checked as three-dimensional coordinates. If positions of the joints are changed, only a vector quantity is transmitted to a receiving side. The receiving side moves the coordinates of the joints being currently displayed, according to the received vector quantity, thereby displaying movements. For instance, a receiving side displays an avatar and a background. Once a transmitting side has transmitted movement information to the receiving side, a holographic call is performed in a state that the avatar is moving.
To the present invention, a hologram image filtering function may be applied. A user may perform a hologram image filtering function by setting colors, black and white, and monogray.
A hologram image applied to the present invention may be used as a flash. More concretely, a bright hologram image may be output through a hologram output unit, and may be used as a flash. Alternatively, a Morse code function may be applied to the present invention. More concretely, a hologram image may be output only when a touch panel, i.e., a management screen is touched, and the mobile terminal may be used as a Morse code output device.
In the present invention, a position of the mobile terminal may be easily detected by using a hologram image. When a user wishes to find his or her mobile terminal at night, the user tries a call or sends a text message (SMS) to a specific number stored in the mobile terminal. Once the call or the text message (SMS) has been received, the controller 180 converts a current mode of the mobile terminal into a hologram mode, and outputs a preset hologram image through a hologram output unit. This may allow the
user to easily find the mobile terminal based on the output hologram image. Especially, when the mobile terminal has been set to be mute, the controller 180 may output sound together with the hologram image.
In the present invention, a hologram image (2D or 3D) is stored in the memory 160. However, due to a very large capacity, only a hologram image corresponding to a specific section selected by a user may be stored, or a hologram image may be stored in a compression manner. If necessary, a 3D-hologram image may be stored after being converted into a 2D-hologram image. Alternatively, a text hologram image may be stored after being converted into a text, thereby enhancing efficiency of a storage space.

Once the hologram image has been displayed, the user performs a multi-touch on the management screen, and the controller 180 detects the multi-touch thereby to perform a rotation, an enlargement/contraction, a screen-out, etc. with respect to the hologram image (S31, S32). The user's manipulation may be performed through a direct touch on the hologram image. In this case, the controller 180 performs an enlargement/contraction, an exchange, a movement, etc. with respect to the hologram image according to the user's multi-touch, between one hologram output unit and the display unit 151, or between one hologram output unit and another hologram output unit.
The controller 180 detects shake of the mobile terminal during a video call and peripheral circumstances (S33), thereby controlling a background color of a hologram image being currently displayed, or maintaining a horizontal state of a hologram image (S34). When performing a video call by using one or more hologram output units, the controller 180 controls each operation such as an exchange, a movement and a copying of a hologram image between hologram output units, according to a user's touch input.
As aforementioned, in the present invention, texts, moving images, contents, etc. are displayed as a hologram image. And, the displayed hologram image may be variously controlled according to a user's touch. This may solve spatial limitations of a general mobile terminal, and may implement a holographic video call more effectively.
The aforementioned method may be implemented as a program code stored in a computer-readable storage medium. The storage medium may include ROM, RAM, CD-ROM, a magnetic tape, a floppy disc, an optical data storage device, etc. And, the storage medium may be implemented as carrier wave (transmission through the Internet). The computer may include the controller of the mobile terminal.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present disclosure.
