In addition, the TV 200 generates a synchronizing signal synchronized with a timing in which the left eye image and the right eye image are time-divided and displayed, and transmits the synchronization signal to the shutter glass 300.

Meanwhile, the remote controller 400 receives an operation command for controlling the TV 200 from the user and transmits the input operation command to the TV 200. In addition, the remote control 400 has a color button consisting of an R-button, a G-button, a Y-button, and a B-button, and each color button operates as a shortcut for enabling a user to execute a predetermined function. Done.

Hereinafter, referring to FIG. 3 for a more detailed description of the TV 200. 3 is a block diagram of a TV 200 according to an embodiment of the present invention.

As shown, the TV 200 according to the present embodiment includes an image receiver 210, an image processor 220, an image outputter 230, a controller 240, and a graphical user interface (GUI) generator 250. , A storage unit 260, a user command receiver 270, and an IR transmitter 280.

The image receiver 210 receives and demodulates a broadcast received by wire or wireless from a broadcasting station or a satellite. In addition, the image receiver 210 is connected to an external device such as the camera 100 to receive a 3D image from the external device. External devices can be connected wirelessly or wired through interfaces such as S-Video, Component, Composite, D-Sub, DVI, and HDMI.

As described above, the 3D image is an image composed of at least one frame, and includes a left eye image and a right eye image in one image frame or an image in which each frame consists of a left eye image or a right eye image. That is, the 3D image is an image generated according to one of the formats according to FIG. 2 described above.

Accordingly, the 3D image received by the image receiving unit 210 may be in various formats, and in particular, among the general frame sequence method, top-bottom method, side by side method, horizontal interleave method, vertical interleave method, and checkerboard method. It may be in a format according to one.

The image receiver 210 transmits the received 3D image to the image processor 220.

The image processor 220 performs a signal processing such as video decoding, format analysis, video scaling, and GUI addition, etc. on the 3D image received by the image receiver 210.

In particular, the image processor 220 generates a left eye image and a right eye image corresponding to the size of one screen (1920 * 1080), respectively, using the format of the 3D image input to the image receiver 210.

That is, when the format of the 3D image is a top-bottom, side-by-side, horizontal interleaved, vertical interleaved, or checkerboard method, the image processor 220 performs a left eye image and a right eye image in each image frame. Each part is extracted and the left and right eye images are enlarged and scaled or interpolated to generate left and right eye images for providing to the user.

In addition, when the format of the 3D image is a general frame sequence method, the image processor 220 may prepare to extract a left eye image or a right eye image from each frame and provide the same to the user.

Meanwhile, the information about the format of the input 3D image may or may not be included in the 3D image signal.

For example, when the information on the format of the input 3D image is included in the 3D image signal, the image processor 220 analyzes the 3D image to extract information about the format, and the received 3D according to the extracted information. The image is processed. On the other hand, when the information about the format of the input 3D image is not included in the 3D image signal, the image processor 220 processes the 3D image received according to the format input from the user or received the 3D image according to a preset format. The image is processed.

In addition, the image processor 220 allows the GUI received from the GUI generator 250 to be described later to be added to the left eye image, the right eye image, or both.

The image processor 220 time-divisions the extracted left eye image and the right eye image, and alternately transfers the extracted left eye image to the image output unit 230. That is, the image processing unit 220 is a left eye image (L1)-> right eye image (R1)-> left eye image (L2)-> right eye image (R2)->. The left eye image and the right eye image are transmitted to the image output unit 230 in a temporal order of '.

The image output unit 230 alternately outputs the left eye image and the right eye image output from the image processor 220 and provides the same to the user.

The GUI generator 250 generates a GUI to be displayed on the display. The GUI generated by the GUI generator 250 is applied to the image processor 220 to be added to the left eye image, the right eye image, or both to be displayed on the display.

The storage unit 260 is a storage medium that stores various programs necessary for operating the TV 200, and may be implemented as a memory, a hard disk drive (HDD), or the like.

The user command receiver 270 transmits a user command received from an input means such as the remote controller 400 to the controller 240.

The IR transmitter 280 generates a synchronization signal synchronized with the left eye image and the right eye image that are alternately output, and transmits the generated synchronization signal to the shutter glass 300 in an infrared form. This is because, through synchronization between the TV 200 and the shutter glass 300, the shutter glass 300 is alternately opened and closed so that the left eye image is displayed on the image output unit 230 at the left eye open timing of the shutter glass 300. The right eye image is displayed on the image output 230 at the right eye opening timing of the shutter glass 300.

The controller 240 controls the overall operation of the TV 200 according to the user command received from the user command receiver 270.

In particular, the controller 240 controls the image receiving unit 210 and the image processing unit 220 so that a 3D image is received, the received 3D image is divided into a left eye image and a right eye image, respectively. Allows scaling or interpolation to a size that can be displayed on this single screen.

In addition, the controller 240 controls the GUI generator 250 to generate a GUI corresponding to the user command received from the user command receiver 270, and controls the IR transmitter 280 to control the left eye image and A synchronization signal synchronized with the output timing of the right eye image is generated and transmitted.

Meanwhile, the shutter glass 300 alternately opens and closes the left eye glass and the right eye glass according to the synchronization signal received from the TV 200, so that the user can view the left eye image and the right eye image through the left eye and the right eye, respectively. Hereinafter, a detailed configuration of the shutter glass 300 will be described with reference to FIG. 4.

4 is a block diagram of a shutter glass 300 according to an embodiment of the present invention. As illustrated, the shutter glass 300 includes an IR receiver 310, a controller 320, a glass driver 330, and a glass 340.

The IR receiver 310 receives a synchronization signal for the 3D image from the IR transmitter 280 of the TV 200 connected by wire or wirelessly. In particular, the IR transmitter 280 emits a synchronization signal by using infrared rays having straightness, and the IR receiver 310 receives a synchronization signal from the emitted infrared rays.

For example, the synchronization signal transmitted from the IR transmitter 280 to the IR receiver 310 may be a signal in which a high level and a low level are alternated at predetermined time intervals. The left eye image may be transmitted in time, and the right eye image may be transmitted in a low level time.

The IR receiver 310 transmits the synchronization signal received from the IR transmitter 280 to the controller 320.

The controller 320 controls the overall operation of the shutter glass 300. In particular, the controller 320 generates a control signal based on the synchronization signal received from the IR receiver 310, and transfers the generated control signal to the glass driver 330 to control the glass driver 330. In particular, the controller 320 controls the glass driver 330 such that a driving signal for driving the glass unit 340 is generated by the glass driver 330 based on the synchronization signal.

The glass driver 330 generates a driving signal based on the control signal received from the controller 320. In particular, since the glass unit 340 to be described later is composed of the left eye glass 350 and the right eye glass 360, the glass driver 330 is the left eye driving signal and the right eye glass 360 for driving the left eye glass 350. Each of the right eye driving signals is generated to transmit the left eye driving signal to the left eye glass 350 and the right eye driving signal to the right eye glass 360.

As described above, the glass unit 340 includes a left eye glass 350 and a right eye glass 360, and opens and closes each glass according to a driving signal received from the glass driver 330.

According to such a format, the TV 200 divides each frame of the received 3D image into left and right parts and separates the left eye image portion and the right eye image portion, and enlarges the separated left eye image portion and the right eye image portion twice to the left and right. The left eye image and the right eye image to be displayed on the screen by scaling are generated, and the generated left eye image and the right eye image are alternately displayed on the screen.

Accordingly, the 3D image may include a left eye image in which the left portion L1 is doubled in the image included in the first frame, and a right eye image in which the right portion R1 is doubled in the image included in the first frame. > Left eye image in which the left part L2 is enlarged 2 times among images included in the second frame-> Right eye image in which the right part R2 is enlarged 2 times among the images included in the second frame->. It is displayed on the screen in the order of '.

On the other hand, the process for processing the format of the 3D image according to the side-by-side method has been described as an example, but the process of processing the format of the 3D image according to the top-bottom method can be inferred therefrom. That is, when the 3D image is formatted according to the top-bottom method, the TV 200 divides each frame of the received 3D image up and down, and separates the left eye image portion and the right eye image portion, respectively. The left and right eye images to be displayed on the screen are generated by expanding and scaling the portion and the right eye image up and down twice, and the left and right eye images are alternately displayed on the screen.

In particular, the format of the 3D image according to the horizontal interleaving method is a format in which the left eye image and the right eye image are alternately arranged in rows.

According to this format, the TV 200 divides each frame of the received 3D image into odd rows and even rows, and separates the left eye image portion and the right eye image portion, and separates the separated left eye image portion and the right eye image portion. The left eye image and the right eye image are generated by 2 times magnification scaling, and the generated left eye image and the right eye image are alternately displayed on the screen.

Accordingly, the 3D image includes a left eye image in which the odd row portions L1-1 and L1-2 are enlarged twice by two times, and the right portion R1-in the image included in the first frame. 1, R1-2), respectively, 2 times magnified right eye image-> Left portion (L2-1, L2-2) of the image included in the second frame, respectively, 2 times in the left eye image-> included in the second frame Right eye image in which the right portions R2-1 and R2-2 are enlarged twice by 2 times. It is displayed on the screen in the order of '.

Of course, for the format of the 3D image according to the horizontal interleaving method, the left eye image is generated by interpolating even row portions using odd row portions among the images included in one frame without using the above-described scaling scaling method. It may be possible to generate a right eye image by interpolating odd row parts using the row parts.

In addition, a left eye image may be generated by outputting an image only for odd rows, and a right eye image may be generated by outputting an image only for even rows without using an enlarged scaling method or an interpolation method.

In the above description, a process of processing a format of a 3D image according to a horizontal interleaving method has been described as an example, but a process of processing a format of a 3D image according to a vertical interleaving method or a checkerboard method may be inferred therefrom. .

That is, the 3D image may be provided to the user by alternately generating a left eye image and a right eye image by applying column scaling or interpolation instead of row scaling or interpolation in the vertical interleave format.

In addition, as for the format of the 3D image according to the checkerboard method, pixel scaling or interpolation, pixel group scaling or interpolation may be used.

<Screen composition of 3D image according to user's operation>

Hereinafter, a screen configuration of a 3D image according to a user's operation will be described with reference to FIGS. 6 to 8.

6 is a diagram illustrating a screen when a 3D image is received.

When the 3D image is received, the TV 200 automatically analyzes a format to be applied to the received 3D image and processes the 3D image according to the analyzed format to be displayed on the screen. For example, if the received 3D image is generated in a format according to the top-bottom method, the TV 200 knows a format to be applied to the received image using format information added to the received 3D image. It becomes possible.

As such, when the format to be applied to the received 3D image is known, the TV 200 applies the format to the received 3D image, extracts the left eye image portion and the right eye image portion from the 3D image, and extracts the extracted left eye image. The left eye image and the right eye image are generated by expanding and scaling the portion and the right eye image in the vertical direction, and the left and right eye images are time-divided and displayed alternately.

FIG. 6 illustrates a 3D object 610 in which a circular left eye image and a circular right eye image are overlapped for a graphic representation of a 3D image that is time-divided and displayed alternately.

In addition, a GUI 620 for automatically guiding various setting changes for the 3D image is automatically added to the screen together with the 3D object 610.

The GUI 620 includes an item set 620 for changing various settings, and the item set 620 includes an item for changing a format, an item for switching to a 2D image, and a 3D image. An item for changing the output order of the left eye image and the right eye image, and an item for converting the output state of the 3D image.

Accordingly, the user can change the output state for the item for changing the format, the item for switching to the 2D image, the item for changing the output order of the left and right eye images constituting the 3D image, and the 3D image. By selecting one of the items, it is possible to change the format of the 3D video, to convert the 3D video to a 2D video, to change the output order of the 3D video, or to change the output state of the 3D video.

As described above, the format change means a change to a format according to one of a frame sequence method, a top-bottom method, a side by side method, a horizontal interleaved method, a vertical interleaved method, and a checkerboard method.

The 2D method refers to a method of displaying a received 3D image in a 2D form. In order to display the 3D image according to the 2D method, the left eye image and the right eye image are time-divided so that only the left eye images or only the right eye images are displayed. As a result, the 2D image in which the stereoscopic effect has disappeared is displayed.

The output order means that the left eye image and the right eye image included in one image frame are output in the order of left eye image-> right eye image or in the order of right eye image-> left eye image.

The output state means whether the 3D image is being output while the 3D mode is ON or the 3D image is being output when the 3D mode is OFF.

When the 3D mode is turned on, each image frame included in the input 3D image is divided into a left eye portion and a right eye portion according to an applied format, and the left eye is enlarged and scaled for the separated left eye portion and the right eye image portion. This means that the image and the right eye image are generated, and the left and right eye images are time-divided and displayed alternately.

On the other hand, when the 3D mode is turned off, it means that each image frame included in the input 3D image is displayed as it is. Therefore, in this case, if the 3D image is in a format other than the frame sequence scheme, the left eye image and the right eye image are simultaneously displayed.

Meanwhile, color information for guiding selection of each item is added as information about a button necessary for selecting each item around each item included in the item set 630. The color information may be provided by being displayed in text of R, G, Y, and B as shown, or may be provided in actual color.

Therefore, the user can press the R-button provided on the front panel of the TV 200 or the R-button provided on the remote control 400 to transmit a command for changing the format to the TV 200. When a command for changing the format is received, the GUI 620 for guiding various settings is changed to a GUI for changing the format.

In addition, the user may press the G-button provided on the front panel of the TV 200 or the remote controller 400 to switch to the 2D mode, or press the Y-button to change the output order. You can also turn the 3D mode off by pressing the-button.

In addition, as shown, information indicating that a 3D image is provided and an item for stopping display of the GUI 620 may be provided at the top or bottom of the item set 630.

As such, when a 3D image is received, a GUI 620 for automatically analyzing and applying a format to be applied to the 3D image and guiding various settings for the 3D image is displayed, thereby allowing the user to display the 3D image. You can easily and easily change the various settings of the.

7A to 7D are diagrams illustrating a screen in which a GUI is changed by selecting an item included in the GUI.

When the user presses the R-button provided on the TV 200 or the remote controller 400, the screen is switched from the screen of FIG. 6 to the screen of FIG. 7A. That is, when the R-button is pressed, the 3D object 610 is displayed on the screen as it is, and the GUI 640 related to the item indicating the format for applying to the 3D image is displayed.

The item 640 representing the format represents a format according to one of the above-described frame sequence scheme, top-bottom scheme, side by side scheme, horizontal interleaved scheme, vertical interleaved scheme, and checkerboard scheme. In the example shown, the item 640 representing the format represents formats according to the top-bottom, side-by-side, horizontal interleaved, vertical interleaved, checkerboard and frame sequence methods, respectively, from left to right. .

Therefore, when the user operates the left and right operation buttons provided on the front panel of the TV 200 or the left and right operation buttons provided on the remote controller 400, the format for processing the received 3D image is a top-bottom method-> side. By-side-> horizontal interleave method-> vertical interleave method-> checkerboard method-> format according to the frame sequence method or vice versa.

That is, the item 640 indicating the format is not only a format currently applied to the 3D image but also an item for switching the format for the 3D image.

On the other hand, the GUI 640, as shown in the figure, the information indicating the format change state on the top or bottom of the item 640 indicating the format, and items for guiding the user's up and down operation, selection operation, return operation, etc. are added. The format currently applied to the 3D image may be highlighted.

In addition, when the user presses the G-button provided on the TV 200 or the remote controller 400, the screen is switched from the screen of FIG. 6 to the screen of FIG. 7B. That is, when the G-button is pressed, the 3D object 610 disappears from the screen, and only the 2D object 650 according to the 2D image is displayed on the screen.

As described above, the 2D object 650 corresponds to one of an object included in the left eye image and an object included in the right eye image.

In addition, at the bottom of the 2D object 650, the current screen is a screen according to the 2D method, and information for pressing the G-button to switch back to the 3D method is displayed. That is, this information guides the user to watch the video according to the 3D method by pressing the G-button.

That is, when the Y-button is pressed, the 3D object 610 disappears from the screen and the screen on which the output order for the 3D image is changed is displayed. Accordingly, the 3D object 670 may have a different form from the object before the output order is changed.

In addition, at the bottom of the 3D object 670, the current screen is displayed in the order of the right eye image-> left eye image, and information to press the Y-button to switch back to the left eye image-> right eye image is provided. Is displayed. That is, the information guides the user to view the displayed image in the order of the left eye image-> right eye image by pressing the Y-button.

In addition, when the user presses the B-button provided on the TV 200 or the remote controller 400, the screen is switched from the screen of FIG. 6 to the screen of FIG. 7D. That is, when the B-button is pressed, the 3D object 610 disappears from the screen and the 2D object 690 is displayed on the screen instead. The 2D object 690 is an object displayed on the screen because the 3D mode is turned off, unlike the object displayed on the screen according to the 2D method.

That is, instead of displaying one of the object included in the left eye image and the object included in the right eye image, each image frame included in the input 3D image is displayed as it is, so that the 3D image is based on a method other than a frame sequence method. In the case of the format, it means that both the object included in the left eye image and the object included in the right eye image are displayed.

In addition, at the bottom of the 2D object 690, the current 3D function is turned off, and information for pressing the B-button to turn on the 3D function is displayed. That is, this information guides the user to press the B-button to change the 3D mode OFF to the 3D mode ON state.

This makes it easier and easier to change various settings of the 3D image.

8 is a diagram for explaining screen switching when there is no user operation. As shown in the drawing, if a 3D image is received and a GUI 620 for guiding various setting changes for the 3D image is automatically added together with the 3D object 610, and then no command is input from the user, The GUI 620 obstructing viewing is automatically disappeared.

In addition, the user may press a specific button, such as the ENTER-button, to cause the GUI 620 to disappear manually.
