DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

As used herein, the suffixes “module” and “unit” are added to simply facilitate preparation of this specification and are not intended to suggest special meanings or functions. Therefore, the suffixes “module” and “unit” may be used interchangeably.

FIG. 1 illustrates an image display system for mirroring according to an embodiment of the present invention.

Referring to FIG. 1, an image display system 10 for mirroring may include an image display apparatus 100, a mobile terminal 600 and a server 500.

The image display apparatus 100 may perform mirroring with the mobile terminal 600.

In particular, the image display apparatus 100 may receive a mirroring image from the mobile terminal 600 and display the mirroring image on a display 180.

If there is a blank area in addition to a display area for display of a mirroring image when mirroring is performed between the image display apparatus 100 and the mobile terminal 600 and thus the mirroring image is displayed by the image display apparatus 100, additional information related to the mirroring image is displayed. In particular, the additional information is displayed in the blank area other than the display area for display of the mirroring image. Thereby, the mirroring image and various kinds of information may be viewed simultaneously when mirroring is performed between the image display apparatus 100 and the mobile terminal 600.

A controller 170 of the image display apparatus 100 may perform a control operation to display a pointer on the display 180, based on a pointing signal from the remote control device 200. In addition, if the pointer is located in the blank area when the mirroring image is displayed, the controller 170 may perform a control operation to display additional information related to the mirroring image in the blank area. By displaying the additional information according to location of the pointer, information serving the user's intention may be displayed.

In displaying the additional information related to the mirroring image in the display area, the controller 170 of the image display apparatus 100 may perform a control operation to move and display the mirroring image. If the amount of data of the additional information is large, the controller 170 of the image display apparatus 100 may control the displayed mirroring image to move or to be scaled down. Thereby, additional information having a large amount of data may be viewed at once.

In addition, the controller 170 of the image display apparatus 100 may perform a control operation to display the pointer on the display based on a pointing signal of the remote control device 200. If the pointer is located in a second area corresponding to the blank area, the back key of the remote control device operates, or the pointer flicks to the left when a mirroring image is displayed, the controller 170 may perform a control operation to display additional information related to the mirroring image in the second area. If the pointer is located in a third area corresponding to the blank area, or the pointer flicks to the right when a mirroring image is displayed, the controller 170 may control the additional information related to the mirroring image display in the third area. By displaying relevant additional information according to movement of the pointer, user convenience may be enhanced.

If the pointer moves from the second area to the third area when a mirroring image is displayed, the controller 170 of the image display apparatus 100 may perform a control operation to display second additional information in the third area with first additional information displayed in the second area.

If the pointer moves from the second area to the third area when a mirroring image is displayed, the controller 170 of the image display apparatus 100 may control the additional information displayed in the second area to disappear and control the additional information to be displayed in the third area.

The additional information may include at least one of an image adjustment item for the mirroring image, a Share item for sharing an image, a previous image for the mirroring image, a next image for the mirroring image, an image list related to the mirroring image, an application item related to the mirroring image and detailed information about the mirroring image.

If the mirroring image is a home screen window or idle screen window of the mobile terminal 600, the controller 170 of the image display apparatus 100 may perform a control operation to display, in the blank area, at least one of an object corresponding to a camera manipulation button attached to the mobile terminal 600, an object corresponding to a power button, an object corresponding to a volume adjustment button and a zooming adjustment button.

If the mirroring image is the home screen window or idle screen window of the mobile terminal 600, the controller 170 of the image display apparatus 100 may perform a control operation to display, in the blank area, at least one of an object indicating a first connector for connection with an external device and an object indicating a second connector for connection with a detachable additional memory.

The controller 170 of the image display apparatus 100 may control additional information related to the mirroring image to vary according to the attribute of the mirroring image.

For example, if the mirroring image is a gallery application, the controller 170 of the image display apparatus 100 may control the additional information to include an image quality adjustment item.

As another example, if the mirroring image is the gallery application, the controller 170 of the image display apparatus 100 may control the additional information to include a Share item for sharing an image or an application item for sharing.

As another example, if the mirroring image is a moving image which is being reproduced, the controller 170 of the image display apparatus 100 may control the additional information to include title information about the moving image, resolution information about the moving image, caption information, actor/actress information, or frequency information.

As another example, if the mirroring image is an image related to a music file which is being reproduced, the controller 170 of the image display apparatus 100 may control the additional information to include title information about the music file, lyrics information, singer information, composer information, or scale information.

As another example, if the mirroring image is a web image, the controller 170 of the image display apparatus 100 may control the additional information to include previous web image or a bookmark item.

As another example, if the mirroring image is a map image, the controller 170 of the image display apparatus 100 may control the additional information to include a map image of an area is not displayed, information about locations in the map image or shop name information.

As another example, if the mirroring image is the home screen window or idle screen window of the mobile terminal 600, the controller 170 of the image display apparatus 100 may control the additional information to include at least one of an object corresponding to a camera manipulation button attached to the mobile terminal 600, an object corresponding to a power button, an object corresponding to a volume adjustment button and an object corresponding to a zooming adjustment button.

As another example, if the mirroring image is the home screen window or idle screen window of the mobile terminal 600, the controller 170 of the image display apparatus 100 may control the additional information to include at least one of an object indicating a first connector for connection with an external device and an object indicating a second connector for connection with a detachable additional memory.

The controller 170 of the image display apparatus 100 may control a mirroring image received from the mobile terminal to be scaled and displayed in a first area of the display and perform a control operation to display additional information related to the mirroring image in a second area corresponding to a blank area.

To perform mirroring between the image display apparatus 100 and the mobile terminal 600, pairing needs to be performed between the image display apparatus 100 and the mobile terminal 600.

In this embodiment, a method for easily performing pairing between the image display apparatus 100 and the mobile terminal 600 is proposed.

The controller 170 of the image display apparatus 100 may perform a control operation to display a device connection application item according to a predetermined input, and display an image including server information such that the image is captured based on selection of the device connection application item using the mobile terminal 600. Thereafter, the controller 170 may perform pairing with the mobile terminal 600. Once pairing is completed, the controller 170 may perform a control operation to display an object indicating the paired mobile terminal 600.

In particular, after displaying the image including the image the server information such that the image is captured using the mobile terminal 600, the controller 170 of the image display apparatus 100 may perform a control operation to display randomly produced code information. Then, reliable and convenient pairing may be performed through pairing with the mobile terminal 600 after display of the code information. Further, completion of the pairing may be easily recognized.

If pairing with the mobile terminal 600 is performed while an image is being displayed on the display 180, the controller 170 of the image display apparatus 100 may perform a control operation to display an object indicating the paired mobile terminal 600 in the image. Thereby, completion of the pairing may be easily recognized while the displayed image is viewed.

If pairing with the mobile terminal 600 is performed while a broadcast image based on a broadcast signal received from a broadcast receiver 105 is being displayed, the controller 170 of the image display apparatus 100 may perform a control operation to display an object indicating the paired mobile terminal 600.

To perform pairing, the image display apparatus 100 may wirelessly transmit a pairing signal, and the mobile terminal 600 may transmit a pairing response signal in response to the pairing signal. Thereby, pairing may be performed and the mobile terminal 600 and the image display apparatus 100 may be connected to each other.

Herein, the pairing signal and the pairing response signal may be Bluetooth low energy (BLE) signals. In particular, the image display apparatus 100 may periodically transmit a BLE pairing signal.

In addition to the pairing signal, the image display apparatus 100 may further transmit device information including the device ID of the image display apparatus.

If the object indicating the paired mobile terminal 600 is selected, the controller 170 of the image display apparatus 100 may perform a control operation to display an application list related to the paired mobile terminal 600.

When a first application item is selected in the application list related to the paired mobile terminal 600, the controller 170 may send a request for a screen window related to the first application to the mobile terminal 600, and perform a control operation to display an image for execution of the first application on the display based on information received from the mobile terminal 600.

That is, when the first application item is selected in the application list related to the paired mobile terminal 600, the controller 170 may perform a control operation to implement mirroring.

The communication scheme for pairing may be different from the communication scheme for mirroring.

To improve data transfer rate in performing mirroring, if the source of moving images reproduced in the mobile terminal 600 is a coded video signal, the mobile terminal 600 may transmit the coded video signal to the image display apparatus 100 without decoding and reproducing the coded video signal, and the image display apparatus 100 may decode the coded video signal and reproduce and display the decoded video signal.

If the mobile terminal 600 approaches the image display apparatus 100 within a predetermined distance allowing pairing, the controller 170 of the image display apparatus 100 may perform pairing.

The controller 170 may perform a control operation to transmit a pairing signal. If the mobile terminal 600 approaches within a predetermined distance enabling pairing, the controller 170 may receive a pairing response signal from the mobile terminal 600, and perform pairing based on the pairing response signal.

As described above, the image display apparatus 100 may transmit a pairing signal, and the mobile terminal 600 may transmit a pairing response signal. Alternatively, the mobile terminal 600 may transmit a pairing signal, and the image display apparatus 100 may transmit a pairing response signal.

If the image display apparatus 100 is additionally paired with a second mobile terminal 600 while an object indicating the paired mobile terminal is displayed, the controller 170 of the image display apparatus 100 may perform a control operation to display the second object indicating the paired second mobile terminal 600 in addition to the first object.

When the second object indicating the paired second mobile terminal is selected, the controller 170 of the image display apparatus 100 may perform a control operation to display a second application list related to the paired second mobile terminal.

If the second object indicating the second paired mobile terminal 600 is selected after the object indicating the mobile terminal 600 is selected and the application list related to the paired mobile terminal 600 is displayed, the controller 170 of the image display apparatus 100 may perform a control operation to display a second application list related to the second paired mobile terminal 600.

In addition, if the second object indicating the second paired mobile terminal 600 is selected after the object indicating the mobile terminal 600 is selected and the application list related to the paired mobile terminal 600 is displayed, the controller 170 of the image display apparatus 100 may perform a control operation to display a user change object and a user addition object. When the user change object is selected, the controller 170 may perform a control operation to display the second application list related to the second paired mobile terminal 600.

A more detailed description of various methods for operating the image display apparatus 100 and the mobile terminal 600 will be given with reference to FIG. 6.

The image display apparatus 100 of FIG. 1 may be a monitor, TV, Tablet PC, or other types of image display apparatus.

FIG. 2 is an internal block diagram illustrating the image display apparatus of FIG. 1.

Referring to FIG. 2, the image display apparatus 100 according to an embodiment may include a broadcast receiver 105, an external device interface unit 130, a storage unit 140, a user input interface unit 150, a sensor unit, a controller 170, a display 180, and an audio output unit 185.

The broadcast receiver 105 may include a tuner 110, a demodulator 120, a network interface unit 135, and an external device interface unit 130.

In contrast with the example of the figure, the broadcast receiver 105 may include only the tuner 110, the demodulator 120, and the external device interface unit 130. That is, the network interface unit 135 may not be included.

The tuner 110 selects a channel selected by a user from among radio frequency (RF) broadcast signals received through an antenna or an RF broadcast signal corresponding to all pre-stored channels. In addition, the tuner 110 converts the selected RF broadcast signal into a middle-frequency signal, a base band image, or a voice signal.

For example, if the selected RF broadcast signal is a digital broadcast signal, the signal is converted into a digital IF (DIF) signal. If the selected RF broadcast signal is an analog broadcast signal, the signal is converted into a baseband image or a voice signal (CVBS/SIF). That is, the tuner 110 may process a digital broadcast signal or an analog broadcast signal. The analog baseband image or voice signal (CVBS/SIF) output from the tuner 110 may be directly input to the controller 170.

In this embodiment, the tuner 110 may sequentially select an RF broadcast signal for all stored broadcast channels from among RF broadcast signals received through the antenna through the channel memorization function, and convert the same into a middle-frequency signal, baseband image, or voice signal.

To receive broadcast signals of two or more channels, two or more tuners 110 may be provided. Alternatively, a single tuner to receive two or more channels simultaneously may be provided.

The demodulator 120 receives and demodulates the DIF signal converted by the tuner.

After performing demodulation and channel decoding, the demodulator 120 may output a stream signal (TS). Herein, the stream signal may be a signal obtained by multiplexing an image signal, voice signal or data signal.

The stream signal output from the demodulator 120 may be input to the controller 170. After performing demultiplexing and image/voice signal processing, the controller 170 outputs an image to the display 180 and voice to the audio output unit 185.

The external device interface unit 130 may transmit or receive data to or from a connected external device, e.g., a set-top box 50. Further, the external device interface unit 130 may include an A/V input/output unit.

The external device interface unit 130 may be connected to external devices such as a DVD (digital versatile disk), a Blu-ray, a gaming device, a camera, a camcorder, a computer (laptop), and a set-top box in a wired/wireless manner, and perform input/output operations with external devices.

The A/V input/output unit may receive image and voice signals input from a external device. A wireless communication unit may perform short-range wireless communication with other electronic devices.

The external device interface unit 130 may exchange data with a neighboring mobile terminal 600 via the wireless communication unit. In particular, in the mirroring mode, the external device interface unit 130 may receive device information, information about an executed application and an application image from the mobile terminal 600.

The network interface unit 135 provides an interface for connection with a wired/wireless network including the Internet. For example, the network interface unit 135 may receive content or data provided by a content provider or a network operator over a network.

The network interface unit 135 may include a wireless communication unit.

The storage unit 140 may store programs for processing and control of signals in the controller 170, and also store a signal-processed image, voice signal or data signal.

The storage unit 140 may function to temporarily store an image signal, a voice signal or a data signal input through the external device interface unit 130. In addition, the storage unit 140 may store information about a predetermined broadcast channel through the channel memorization function such as a channel map.

While it is illustrated in FIG. 2 that the storage unit 140 is provided separately from the controller 170, embodiments of the present invention are not limited thereto. The storage unit 140 may be provided in the controller 170.

The user input interface unit 150 may transmit a signal input by the user to the controller 170 or transmit a signal from the controller 170 to the user.

For example, the user input interface unit 150 may transmit/receive user input signals such as power on/off, channel selection, and screen window setting to/from the remote control device 200, deliver, to the controller 170, user input signals input through local keys such as a power key, a channel key, a volume key, or a setting key, deliver, to the controller 170, user input signals input through a sensor unit configured to sense gesture of the user, or transmit a signal from the controller 170 to the sensor unit.

The controller 170 may demultiplex streams input through the tuner 110, demodulator 120, network interface unit 135 or external device interface unit 130, or process demultiplexed signals. Thereby, the controller 170 may generate an output signal for outputting an image or voice.

An image signal image-processed by the controller 170 may be input to the display 180 and an image corresponding to the image signal may be displayed. In addition, the image signal which is image-processed by the controller 170 may be input to an external output device through the external device interface unit 130.

A voice signal processed by the controller 170 may be output to the audio output unit 185 in the form of sound. In addition, the voice signal processed by the controller 170 may be input to an external output device through the external device interface unit 130.

In FIG. 2, the controller 170 may include a demultiplexer and an image processor, which will be described with reference to FIG. 3 later.

Additionally, the controller 170 may control overall operation of the image display apparatus 100. For example, the controller 170 may control the tuner 110 to tune in RF broadcasting corresponding to a channel selected by the user or a pre-stored channel.

The controller 170 may control the image display apparatus 100 according to a user command input through the user input interface unit 150 or an internal program.

The controller 170 may control the display 180 to display an image. Herein, the image displayed on the display 180 may be a still image, a moving image, a 2D image, or a 3D image.

The controller 170 may perform a control operation to display the predetermined 2D object in an image displayed on the display 180. For example, the object may be at least one of an accessed web page (a newspaper, a magazine, etc.), an EPG (electronic program guide), various menus, a widget, an icon, a still image, a moving image and a text.

The controller 170 may recognize the location of the user based on an image captured by a capture unit. For example, the controller 170 may recognize the distance between the user and the image display apparatus 100 (i.e., a z-axis coordinate). Additionally, the controller 170 may recognize an x-axis coordinate and y-axis coordinate corresponding to the location of the user in the display 180.

The display 180 generates drive signals by converting an image signal, data signal, OSD signal, and control signal processed by the controller 170 or an image signal, data signal and control signal received from the external device interface unit 130.

The display 180 may be a PDP, A LCD display, OLED display, a flexible display, or a 3D display. The 3D display 180 may be divided into a non-glasses type and a glasses type.

The display 180 may be configured by a touchscreen to be used not only as an output device but also as an input device.

The audio output unit 185 receives a voice signal processed by the controller 170 and outputs voice.

The capture unit captures an image of the user. The capture unit (not shown) may be implemented using one camera. However, embodiments of the present invention are not limited thereto. The capture unit may be implemented using two or more cameras. The capture unit may be buried in the upper portion of the display 180 of the image display apparatus or may be separately disposed. Image information captured by the capture unit may be input to the controller 170.

The controller 170 may sense gesture of the user based on an image captured by the capture unit, a sensed signal from the sensor unit, or a combination thereof.

The power supply 190 supplies power to overall parts of the image display apparatus 100. In particular, the power supply 190 may supply power to the controller 170, which may be implemented in the form of system on chip (SOC), the display 180 for display of images, and the audio output unit 185 for outputting audio signals.

Specifically, the power supply 190 may include a converter to convert alternating current (AC) power into direct current (DC) power and a DC-DC converter to change the level of the DC power.

The remote control device 200 transmits a user input to the user input interface unit 150. Further, the remote control device 200 may employ Bluetooth, radio frequency (RF) communication, infrared (IR) communication, ultra-wideband (UWB), or ZigBee. In addition, the remote control device 200 may receive an image signal, a voice signal or a data signal from the user input interface 150, and display or output the same.

The image display apparatus 100 may be a fixed or mobile digital broadcast receiver capable of receiving digital broadcast services.

The block diagram of the image display apparatus 100 shown in FIG. 2 is simply illustrative. Constituents of the block diagram may be integrated, added or omitted according to the specification of the image display apparatus 100 which is implemented in reality. That is, two or more constituents may be combined into one constituent, or one constituent may be subdivided into two or more constituents, when necessary. In addition, the function performed in each block is simply illustrative, and it should be noted that specific operations or devices of the blocks do not limit the scope of the present invention.

FIG. 3 is an internal block diagram illustrating the controller of FIG. 2.

Referring to FIG. 3, the controller 170 according to an embodiment of the present invention may include a demultiplexer 310, an image processor 320, a processor 330, an OSD generator 340, a mixer 345, a frame rate converter 350, and a formatter 360.

The demultiplexer 310 demultiplexes an input stream. For example, when MPEG-2 TS is input, the demultiplexer 310 may demultiplex the same to separate the stream into an image signal, a voice signal and a data signal. Herein, the stream signal input to the demultiplexer 310 may be a stream signal output from the tuner 110, the demodulator 120 or the external device interface unit 130.

The image processor 320 may perform image processing on a demultiplexed image signal. Further, the image processor 320 may include an image decoder 325 and a scaler 335.

The image decoder 325 decodes the demultiplexed image signal, and the scaler 335 scales the resolution of the decoded image signal such that the image signal can be output through the display 180.

The image decoder 325 may include decoders of various standards. For example, the image decoder 325 may include an MPEG-2, an H.264 decoder, a 3D image decoder for color images and depth images, and a decoder for multi-viewpoint images.

The processor 330 may control overall operation of the image display apparatus 100 or the controller 170. For example, the processor 330 may control the tuner 110 to tune in RF broadcasting corresponding to a channel selected by the user or a pre-stored channel.

In addition, the processor 330 may control the image display apparatus 100 according to a user command input through the user input interface unit 150 or an internal program.

The processor 330 may control data transmission with the network interface unit 135 or the external device interface unit 130.

The processor 330 may control operations of the demultiplexer 310, image processor 320 and OSD generator 340 in the controller 170.

The OSD generator 340 generates an OSD signal automatically or according to user input. For example, the OSD generator 340 may generate a signal for display of various kinds of information in the form of graphic images or texts on the screen of the display 180 based on a user input signal. The generated OSD signal may include various data including the user interface screen window of the image display apparatus 100, various menu screen windows, widget, and icons. The generated OSD signal may also include a 2D object or a 3D object.

The OSD generator 340 may generate a pointer which can be displayed on the display, based on a pointing signal input from the remote control device 200. In particular, the pointer may be generated by a pointing signal processor, and the OSD generator 340 may include the pointing signal generator. Of course, it is possible to provide the pointing signal processor separately from the OSD generator 340.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 with an image signal processed and decoded by the image processor 320. The mixed image signal is provided to the frame rate converter 350.

The frame rate converter (FRC) 350 may convert the frame rate of an input image. The FRC 350 may output the frame rate without performing separate frame rate conversion.

The formatter 360 may arrange a left image frame and right image frame of a 3D image produced through frame rate conversion. The formatter 360 may output a synchronization signal Vsync to open the left eye glass or right eye glass of a 3D view apparatus.

The formatter 360 may change the format of an input image signal to a format in which the corresponding image can be displayed on the display.

The formatter 360 may change the format of a 3D image signal. For example, the formatter 360 may change the format of the 3D image signal to one of various 3D formats including a side-by-side format, a top/down format, a frame sequential format, an interlaced format, and a checker box format.

The formatter 360 may convert a 2D image signal into a 3D image signal. For example, the formatter 360 may detect an edge or a selectable object in a 2D image signal, and separate and generate the object according to the detected edge of the selectable object as a 3D image signal. In this instance, the generated 3D image signal may be separated into a left image signal L and a right image signal R to be aligned.

In FIG. 3, a 3D processor for 3-dimensional effect signal processing may be further disposed after the formatter 360. The 3D processor may perform processing such as adjustment of brightness, tint and color of an image signal to improve the 3D effect. For example, signal processing of making parts at a close distance clear and making parts at a far distance blurred may be performed. Such function of the 3D processor may be integrated into the formatter 360 or the image processor 320.

An audio processor in the controller 170 may process a demultiplexed voice signal. Further, the audio processor may include various decoders.

The audio processor in the controller 170 may perform processing such as adjustment of bass, treble, and volume.

The data processor in the controller 170 may perform data processing on a demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, the data processor may decode the data signal. The coded data signal may be electronic program guide information including broadcast information such as a start time and end time of a broadcast program broadcast on each channel.

The block diagram of the controller 170 shown in FIG. 3 is illustrative. Constituents of the block diagram may be integrated, added or omitted according to the specification of the controller 170 which is implemented.

FIG. 4 illustrates a method for controlling the remote control device of FIG. 2.

As shown in (a) of FIG. 4A, a pointer 205 corresponding to the remote control device 200 may be displayed on the display 180.

The user may move the remote control device 200 up and down, left and right ((b) of FIG. 4A), or back and forth ((c) of FIG. 4A) or rotate the same. The pointer 205 displayed on the display 180 of the image display apparatus corresponds to movement of the remote control device 200. As shown in the figure, because the pointer 205 moves according to movement of the remote control device 200 in the 3D space, the remote control device 200 may be referred to as a spatial remote control or a 3D pointing device.

(b) of FIG. 4A illustrates where the pointer 205 displayed on the display 180 moves to the left when the user moves the remote control device 200 to the left.

Information about movement of the remote control device 200 sensed through a sensor of the remote control device 200 is transmitted to the image display apparatus. The image display apparatus may calculate coordinates of the pointer 205 based on the information about the movement of the remote control device 200. The image display apparatus may display the pointer 205 such that the pointer 205 corresponds to the calculated coordinates.

(c) of FIG. 4A illustrates where the user moves the controller 170 away from display 180 while pressing down a specific button in the remote control device. In this instance, a selected area on the display 180 corresponding to the pointer 205 may be zoomed in and displayed with the size thereof increased. On the other hand, when the user moves the remote control device 200 closer to the display 180, the selected area may be zoomed out and displayed with the size thereof reduced. Alternatively, the selected area may be zoomed out when the remote control device 200 moves away from the display 180, and may be zoomed in when the remote control device 200 moves closer to the display 180.

Vertical and lateral movement of the remote control device 200 may not be recognized while the specific button in the remote control device 200 is pressed down. That is, when the remote control device 200 approaches or moves away from the display 180, vertical and lateral movements thereof may not be recognized, but only back-and-forth movement thereof may be recognized. If the specific button in the remote control device 200 is not pressed down, the pointer 205 only moves according to vertical and lateral movements of the remote control device 200.

The speed and direction of movement of the pointer 205 may correspond to the speed and direction of movement of the remote control device 200.

The block diagram of the mobile terminal 600 shown in FIG. 5 is simply illustrative. The respective constituents of the block diagram may be integrated, added or omitted according to the specification of the mobile terminal 600 which is implemented in reality. That is, two or more constituents may be combined into one constituent, or one constituent may be subdivided into two or more constituents, when necessary. In addition, the function performed in each block is simply illustrative, and it should be noted that specified operations or devices of the blocks do not limit the scope of the present invention.

FIG. 6 is a flowchart illustrating operation of an image display apparatus and mobile terminal according to an embodiment of the present invention, and FIGS. 7A to 11K illustrate the operation method of FIG. 6.

Referring to FIG. 6, the controller 170 of the image display apparatus 100 determines whether there is a mirroring execution input (S505).

The mirroring execution input may include input for selection of a mirroring application displayed on the image display apparatus 100 or input for selection of a mirroring application displayed on the mobile terminal 600.

When a mirroring execution input is provided, the controller 170 of the image display apparatus 100 determines whether pairing has been performed (S507).

If the distance between the image display apparatus 100 and the mobile terminal 600 is within a predetermined distance, pairing may be automatically performed based on a Bluetooth low energy (BLE)-based pairing signal output from the image display apparatus 100 and a pairing response signal from the mobile terminal 600.

If mirroring has not been performed, the controller 170 of the image display apparatus 100 controls pairing to be performed (S509).

For example, if there is a mirroring execution input, the controller 170 of the image display apparatus 100 may perform a control operation to output a pairing signal and to receive a pairing response signal from the mobile terminal 600 even if the distance between the image display apparatus 100 and the mobile terminal 600 is not within a predetermined distance.

The output level of a pairing signal that is output when the distance between the image display apparatus 100 and the mobile terminal 600 is beyond the predetermined distance is higher than the output level of a pairing signal that is output when the distance between the image display apparatus 100 and the mobile terminal 600 is within the predetermined distance.

If pairing is not performed when the distance between the image display apparatus 100 and the mobile terminal 600 is within the predetermined distance, pairing may be controlled to be performed according to the aforementioned procedure.

Next, when pairing is completed, the controller 170 of the image display apparatus 100 performs a control operation to display a mirroring-related (S510).

For example, when pairing is completed, the controller 170 of the image display apparatus 100 may perform a control operation to display an application list including a mirroring application item.

As another example, when pairing is completed, the controller 170 of the image display apparatus 100 may perform a control operation to display an execution icon indicating the user of a mobile terminal or the mobile terminal.

Then, if the execution icon is selected, the controller 170 of the image display apparatus 100 may perform a control operation to display an application list including a mirroring application item.

Next, if a predetermined application item is selected from the application list, particularly, if the mirroring application item is selected, the controller 170 of the image display apparatus 100 performs a control operation to transmit, via the network interface unit 135, a request for transmission of a mirroring image for the selected application item to the mobile terminal 600 (S615).

Then, the controller 670 of the mobile terminal 600 receives the request for transmission of the mirroring image via the communication unit 610 in response (S517).

Next, the controller 670 of the mobile terminal 600 performs a control operation to execute a corresponding application according to the request for transmission of the mirroring image. Then, the controller 670 performs a control operation to transmit the image of the executed application to the image display apparatus 100 via the communication unit 610 (S520). The image of the executed application is transmitted as a mirroring image.

Next, the controller 670 of the mobile terminal 600 performs a control operation to receive the mirroring image from the mobile terminal 600 and display the moved mirroring image via the network interface unit 135 (S522).

The controller 670 of the mobile terminal 600 determines whether a pointer displayed based on the pointing signal from the remote control device 200 is located in a blank area other than the display area for the mirroring image (S525).

If the pointer is located in the blank area, the controller 170 of the image display apparatus 100 performs a control operation to display additional information related to the mobile terminal or the mirroring image in at least one part of the blank area (S530). As the mirroring image and the additional information related to the mirroring image are displayed together, user convenience may be enhanced.

Examples of the additional information will be described with reference to FIGS. 7A to 11K.

FIG. 7A illustrates where the mobile terminal 600 and the image display apparatus 100 remain connected to each other.

When the mobile terminal 600 and the image display apparatus 100 are wirelessly connected to each other, the controller 170 of the image display apparatus 100 may perform a control operation to display an object 962 indicating a paired mobile terminal on the display 180, as shown in FIG. 7A.

In particular, the controller 170 of the image display apparatus 100 may perform a control operation to display the object 962 indicating the paired mobile terminal on a displayed image 960 on the display 180. Thereby, the user of the mobile terminal or another user who is viewing the image 960 of the image display apparatus 100 may recognize that the mobile terminal is connected and paired with the image display apparatus.

In FIG. 7A, if the object 962 indicating the paired mobile terminal is selected, the controller 170 of the image display apparatus 100 may perform a control operation to display an application list 970 and a wish list 975 which are related to the paired mobile terminal, as shown in FIG. 7B.

The application list 970 related to the paired mobile terminal may include application items for which mirroring can be performed between the mobile terminal 600 and the image display apparatus 100 and an Add item 966.

In the figure, an App Store item, moving image playback item, map item, image viewer item and Internet item are provided as examples of application items for which mirroring can be performed.

If the gallery application item is selected in the application list 970 displayed as shown in FIG. 7B, the controller 170 of the image display apparatus 100 may transmit, to the mobile terminal 600, an application execution request Saib related to the gallery application item. Then, when an application of the mobile terminal 600 related to the gallery application item is executed, the controller 170 may perform mirroring.

Then, in receiving a mirroring image, the controller 170 of the image display apparatus 100 may perform a control operation to display, on the display 180, a screen window 840b of the gallery application which is being displayed as a screen window 840a and executed in the mobile terminal 600, as shown in FIG. 7C.

If a predetermined image item is selected on the displayed screen window 840b of the gallery application, the controller 170 of the image display apparatus 100 transmits selection information to the mobile terminal 600, as shown in FIG. 7C.

The controller 170 of the image display apparatus 100 may receive a mirroring image for the selected image item in response, and perform a control operation to display the mirroring image 1710 in a first area Ara of the display 180, as shown in FIG. 7D.

Typically, the size or resolution of the display 180 of the image display apparatus 100 is greater than the size or resolution of the display 680 of the mobile terminal 600. Accordingly, when the mirroring image is received, the controller 170 of the image display apparatus 100 may perform a control operation to scale up the mirroring image and display the scaled-up mirroring image.

If the screen display position of the mobile terminal 600 is a vertical view position, the display area of the image is limited on the display 180 of the image display apparatus 100, and blank areas Arb and Arc where the image is not displayed are produced.

In this embodiment, additional information related to the mirroring image is displayed in the blank areas.

Herein, the additional information may be automatically displayed in relation to the mirroring image, or optionally displayed according to the location of the pointer 205.

FIG. 7D illustrates disposing a second area Arb and a third area Arc corresponding to blank areas on the left and right sides of the first area Ara of the display 180 in which the mirroring image 1710 is displayed.

The controller 170 of the image display apparatus 100 may receive a pointing signal from the remote control device 200 via the user input interface unit 150, and perform a control operation to display the pointer 205 based on the pointing signal.

In the example of FIG. 7D, the pointer 205 is displayed in the first area Ara of the display 180 in which the mirroring image 1710 is display.

The controller 170 of the image display apparatus 100 may perform a control operation to display the pointer on the display based on the pointing signal. If the pointer is located in the second area corresponding to a blank area, the back key of the remote control device 200 operates, or the pointer 205 flicks to the left in displaying a mirroring image, the controller 170 of the image display apparatus 100 may perform a control operation to display additional information related to the mirroring image in the second area. If the pointer is located in the third area corresponding to a blank area in displaying the mirroring image, the controller 170 may perform a control operation to display additional information related to the mirroring image in the third area. More details will be described with reference to FIGS. 7E and 7F.

When the pointer 205 moves to the second area Arb which is a blank area, the controller 170 of the image display apparatus 100 may perform a control operation to display additional information related to the mirroring image 1710.

In the example of FIG. 7E, an image adjustment item 1722 is displayed in the second area Arb, which is a blank area, as the additional information.

The mirroring adjustment item may include items such as brightness, contrast, and temperature.

If the pointer moves from the second area Arb to the third area Arc in displaying a mirroring image, the controller 170 of the image display apparatus 100 may perform a control operation to display second additional information 1724 in the second area with the first additional information 1722 displayed in the second area Arb, as shown in FIG. 7F.

The second additional information 1724 may include items such as color balance, shadows and highlights as the image adjustment items for the mirroring image 1710.

In contrast with the example of FIG. 7F, if the pointer 205 moves from the second area Arb to the third area Arc in displaying the mirroring image 1710, the controller 170 of the image display apparatus 100 may control the additional information displayed in the second area Arb to disappear, and perform a control operation to display the additional information in the third area.

The additional information displayed in a blank area may include at least one of an image adjustment item for the mirroring image, a Share item for sharing the image, a previous image for the mirroring image, a next image for the mirroring image, an image list related to the mirroring image, an application item related to the mirroring image and detailed information about the mirroring image.

FIG. 8A illustrates display of the mirroring image 1710 in the display area Ara, as illustrated in FIG. 7D.

If the pointer 205 moves to the second area Arb which is a blank area, the controller 170 of the image display apparatus 100 may perform a control operation to display additional information 1810 related to the mirroring image 1710, as shown in FIG. 8B.

In FIG. 8B, the additional information displayed in the second area Arb may include a Share item for sharing images or an application item for sharing images.

When the pointer 205 moves to the third area Arc which is a blank area, the controller 170 of the image display apparatus 100 may perform a control operation to display additional information related to the mirroring image 1710, as shown in FIG. 8C.

In FIG. 8C, the controller 170 of the image display apparatus 100 may perform a control operation to display a previous image 1730 related to the mirroring image 1720 in the second area Arb and a next image 1740 related to the mirroring image 1720 in the third area Arc.

Further, the controller 170 of the image display apparatus 100 may transmit a request for transmission of a previous image or next image related to the mirroring image to the mobile terminal 600 according to the location of the pointer 205. Then, the controller 170 may receive the previous image or next image related to the mirroring image from the mobile terminal 600.

In FIG. 8D, the pointer 205 moves to the second area Arb which is a blank area, the controller 170 of the image display apparatus 100 may perform a control operation to display an image list 1750 related to the mirroring image 1710 as additional information related to the mirroring image 1710.

Further, the controller 170 of the image display apparatus 100 may transmit a request for transmission of the image list 1750 related to the mirroring image to the mobile terminal 600 according to the location of the pointer 205. Then, the controller 170 may receive the image list 1750 related to the mirroring image from the mobile terminal 600.

As the image list is displayed, an image desired by the user may be easily selected, and the selected image item may be transmitted to the mobile terminal 600. Thereby, the selected mirroring image may be easily received from the mobile terminal 600 and displayed.

In displaying additional information related to the mirroring image in a blank area, if the amount of data of the additional information is large or the size of the image indicating the additional information is greater than that of the blank area, the controller 170 of the image display apparatus 100 may perform a control operation to move and display the mirroring image or to display the mirroring image with the image reduced in size.

FIG. 8E illustrates where a mirroring image is moved to the right side such that the mirroring image 1720 is displayed in area Ar1, and the image list 1750 is displayed in area Ar2 as additional information related to the mirroring image.

FIG. 8F illustrates where a mirroring image 1725 which is the mirroring image 1720 reduced in size is displayed in the area Ara without change in the position of the displayed mirroring image, while the mirroring image list 1750 is displayed in the second area Arb which is a blank area.

If the mirroring image is a home screen window of the mobile terminal, the controller 170 of the image display apparatus 100 may perform a control operation to display a second home screen window or third home screen window in the blank area. This operation will be described with reference to FIGS. 9A to 9C.

FIG. 9A illustrates where a main home screen window 1910 of the mobile terminal 600 is displayed in the display area Ara as a mirroring image 1920.

If the pointer 205 moves to the second area Arb which is a blank area, the back key of the remote control device 200 operates, or the pointer 205 flicks to the left, the controller 170 of the image display apparatus 100 may perform a control operation to display a second home screen window 1922 related to the main home screen window 1910 of the mobile terminal 600 as additional information related to the mirroring image 1920, as shown in FIG. 9B.

Further, the controller 170 of the image display apparatus 100 may transmit a request for transmission of the second home screen window related to the mirroring image to the mobile terminal 600 according to the location of the pointer 205. Then, the controller 170 may receive the second home screen window related to the mirroring image from the mobile terminal 600.

As the main home screen window 1920 and the second home screen window 1922 are displayed simultaneously, an application may be easily selected through the image display apparatus 100, contrary to the display 680 of the mobile terminal 600 which is restricted, and the mirroring image for the selected application may be readily received from the mobile terminal 600 and displayed. Thereby, user convenience may be enhanced.

The controller 170 of the image display apparatus 100 may receive the music playback application screen window 2220a displayed in the mobile terminal 600 according to mirroring, and perform a control operation to display a music playback application screen window 2220 in the area Ara as a mirroring screen window, as shown in FIG. 11K.

As shown in FIG. 11K, the music playback application screen window 2220 may include an object 2224 indicating a file list, a playback time and other playback information items and a Pause/Play object 2226.

When the first music item 2222 in the file list is selected by the pointer 205, the controller 170 of the image display apparatus 100 performs a control operation to play back the first music item 2222. That is, the controller 170 of the image display apparatus 100 performs a control operation to transmit a control signal for playback of the first music item 2222 to the mobile terminal 600.

Thereby, the mobile terminal 600 may play the first music item 2222, and transmit a reproduced audio signal to the image display apparatus 100. Herein, because the Bluetooth connection is established, the mobile terminal 600 may not output sound for the first music item 2222 through the speaker thereof.

The controller 170 of the image display apparatus 100 may receive an audio signal corresponding to a first music item which is played back, and perform a control operation to output sound Sout3 corresponding to the audio signal through the speaker. Thereby, a music file stored in the mobile terminal 600 may be conveniently played back through the image display apparatus 100 such that the music can be listened to. In particular, sound with a quality higher than the quality of sound provided by the mobile terminal 600 may be listened to through the speaker of the image display apparatus 100.
