Description

Technical Field [0001] The present invention relates to a GUI providing method for a 3D image and a display device using the same,

The present invention relates to a method of providing a GUI for a 3D image and a display device using the same, and more particularly, to a GUI providing method for displaying a 3D image according to a setting command input by a user, And a 3D image providing system.

3D stereoscopic image technology has various applications such as information communication, broadcast, medical, education and training, military, game, animation, virtual reality, CAD, industrial technology, and the next generation 3D stereoscopic multimedia It can be said that it is core technology of information communication.

Generally, the three-dimensional sensation perceived by a person depends on the degree of thickness change of the lens depending on the position of the object to be observed, the angular difference between both eyes and the object, the difference in position and shape of the object on the left and right eyes, Time difference, and various psychological and memory effects.

Among them, binocular disparity, which is caused by the fact that two eyes of a person are located about 6 to 7 cm away from each other in the horizontal direction, is the most important factor of the stereoscopic effect. In other words, the binocular parallax is used to look at the angular difference of the subject. Due to this difference, the images coming into each eye have different phases. When these two images are transmitted to the brain through the retina, It is possible to feel the original three-dimensional stereoscopic image by precisely fusing each other.

The stereoscopic image display device is classified into a spectacle type using special glasses and a non-aniseed type using no special glasses. The spectrophotometer is a color filter system that separates images using a color filter having a complementary color relationship, a polarizing filter system that separates images of the left eye and the right eye using a light blocking effect by a combination of orthogonal polarizing elements, There is a shutter glass system which can sense a stereoscopic effect by alternately blocking the left and right eyes in response to a synchronizing signal for projecting a video signal on a screen.

Among them, the shutter glass method is a display method using the parallax of both eyes, and it synchronizes the on-off operation of the display device and the on / off of the left and right glasses so that images observed at different angles can recognize the spatial sensation due to the brain action Method.

In the case of the horizontal interleave method, the format of the 3D image is a format including both the left eye image and the right eye image in one frame. In particular, the format of the 3D image according to the horizontal interleave method is a format in which the left eye image and the right eye image are alternately arranged in a row unit.

For this, the left eye image and the right eye image photographed by the camera 100 are scaled down in the vertical direction and converted into resolutions of 1920 * 540, respectively. Thereafter, the converted left eye image and the converted right eye image are converted into odd Alternatively, only one of the odd rows of the left eye image is extracted and only the image of the even-numbered row of the right eye image is extracted, and the image of odd rows and the image of the even rows May be combined to form a single frame.

1, the camera 100 determines a format of one of the above-described formats in advance, generates 3D images according to the determined format, and transmits the generated 3D images to the TV 200. FIG.

The TV 200 is a type of display device that receives a 3D image received from a photographing device such as the camera 100 or a 3D image transmitted from a broadcasting station after being edited / processed in the broadcasting station, Processes the received 3D image and displays it on the screen. In particular, the TV 200 refers to the format of the 3D image, processes the left eye image and the right eye image, and displays the processed left eye image and the right eye image on a time-division basis and displayed alternately.

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

On the other hand, the remote controller 400 receives an operation command for controlling the TV 200 from a user, and transmits the input operation command to the TV 200. [ The remote controller 400 includes color buttons including an R-button, a G-button, a Y-button, and a B-button, and each color button operates as a shortcut key for enabling a user to execute a predetermined function .

Hereinafter, the TV 200 will be described with reference to FIG. 3 for a more detailed description. 3 is a block diagram of a TV 200 according to an embodiment of the present invention.

The TV 200 according to the present embodiment includes an image receiving unit 210, an image processing unit 220, an image output unit 230, a control unit 240, a GUI (Graphic User Interface) A storage unit 260, a user command receiving unit 270, and an IR transmitting unit 280.

The image receiving unit 210 receives and demodulates a broadcast received from a broadcasting station or satellite via a wired or wireless network. The image receiving unit 210 is connected to an external device such as the camera 100 and receives 3D images from an external device. External devices can be connected wirelessly or wired via 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 each frame is composed 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 shown in FIG.

Accordingly, the 3D image received by the image receiving unit 210 may be in various formats. In particular, the 3D image received by the image receiving unit 210 may be in various formats, such as a general frame sequence method, a top-bottom method, a side by side method, a horizontal interleaving method, a vertical interleaving method, And can be in a format according to one.

The image receiving unit 210 transmits the received 3D image to the image processing unit 220.

The image processing unit 220 performs processing such as video decoding, format analysis, video scaling, and the like on the 3D image received by the image receiving unit 210, and GUI addition.

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

That is, when the 3D image format is a format according to the top-bottom, side-by-side, horizontal interleave, vertical interleave, or checkerboard, the image processing unit 220 generates a left- And extracts the left and right eye images, respectively, and enlarges or scales or interpolates the extracted left and right eye images to generate a left eye image and a right eye image for providing to the user, respectively.

If the 3D image format is a general frame sequence scheme, the image processing unit 220 prepares to extract the left eye image or the right eye image from each frame and provide it to the user.

On the other hand, information on the format of the input 3D image may or may not be included in the 3D image signal.

For example, when information on the format of the input 3D image is included in the 3D image signal, the image processing unit 220 extracts information on the format by analyzing the 3D image, And processes the image. On the other hand, when the information on the format of the input 3D image is not included in the 3D image signal, the image processing unit 220 processes the received 3D image according to the format input from the user, And processes the image.

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

The image processing unit 220 time-divides the extracted left eye image and right eye image and transmits them to the image output unit 230 in an alternate manner. That is, the image processing unit 220 generates the left eye image L1, the right eye image R1, the left eye image L2, the right eye image R2, And transmits the left eye image and the right eye image to the image output unit 230 in a temporal order.

The image output unit 230 alternately outputs the left eye image and the right eye image, which are output from the image processing unit 220, to the user.

The GUI generation unit 250 generates a GUI to be displayed on the display. The GUI generated by the GUI generating unit 250 is applied to the image processing unit 220 and added to both the left eye image, the right eye image, or both to be displayed on the display.

The storage unit 260 is a storage medium storing 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 receiving unit 270 transmits a user command received from an input means such as the remote controller 400 to the control unit 240.

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

The control unit 240 controls the overall operation of the TV 200 according to a user command received from the user command receiving unit 270.

In particular, the control unit 240 controls the image receiving unit 210 and the image processing unit 220 to receive a 3D image, separate the received 3D image into a left eye image and a right eye image, To be scaled or interpolated to a size that can be displayed on one screen.

The control unit 240 controls the GUI generating unit 250 to generate a GUI corresponding to the user command received from the user command receiving unit 270 and controls the IR transmitting unit 280 to generate a left eye image and a left eye image, So that a synchronization signal synchronized with the output timing of the right eye image is generated and transmitted.

On the other hand, the shutter glass 300 alternately opens and closes the left eye glass and the right eye glass in accordance with 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 and right eyes, respectively. Hereinafter, a specific configuration of the shutter glass 300 will be described with reference to FIG.

4 is a block diagram of a shutter glass 300 according to an embodiment of the present invention. The shutter glass 300 includes an IR receiving unit 310, a control unit 320, a glass driving unit 330, and a glass unit 340.

The IR receiving unit 310 receives the synchronization signal for the 3D image from the IR transmitting unit 280 of the TV 200 connected by wire or wirelessly. In particular, the IR transmitting unit 280 emits a synchronizing signal using infrared rays having a directivity, and the IR receiving unit 310 receives a synchronizing 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 that is alternated between a high level and a low level at a predetermined time interval, The left eye image is transmitted in the time, and the right eye image is transmitted in the low level time.

The IR receiving unit 310 transmits the synchronizing signal received from the IR transmitting unit 280 to the control unit 320.

The control unit 320 controls operations of the shutter glass 300. In particular, the control unit 320 generates a control signal based on the synchronization signal received by the IR receiving unit 310, and transmits the generated control signal to the glass driving unit 330 to control the glass driving unit 330. In particular, the control unit 320 controls the glass driving unit 330 so that a driving signal for driving the glass unit 340 is generated in the glass driving unit 330, based on the synchronization signal.

The glass driving unit 330 generates a driving signal based on the control signal received from the control unit 320. [ In particular, since the glass portion 340 to be described later is constituted by the left eye glass 350 and the right eye glass 360, the glass driver 330 drives the left eye lens 350 to drive the left eye lens 350 and the right eye glass 360, Eye driving signals to the left eye glass 350 and transmits the right eye driving signals to the right eye glass 360. [

The glass part 340 is constituted by a left eye glass 350 and a right eye glass 360 as described above and opens and closes each glass in accordance with a driving signal received from the glass driving part 330.

≪ Processing process for 3D image >

Hereinafter, a processing procedure for a 3D image will be described with reference to FIGS. 5A to 5C. 5A to 5C are views for explaining a processing method according to the format of a 3D image.

5A shows a method of displaying a 3D image on a screen when a 3D image is received according to a general frame sequence method.

As shown, the format of the 3D image according to the frame sequence scheme is a format in which one left eye image or one right eye image is inserted in one frame. Accordingly, the 3D image is a frame including the left eye image L1 captured by the left eye camera, a frame including the right eye image R1 captured by the right eye camera, a frame containing the left eye image L2 captured by the left eye camera, -> Frames containing the right eye image R2 taken by the right eye camera -> ... ', And they are displayed on the screen in the inputted order.

5B shows a method of displaying a 3D image on a screen when the 3D image is received according to the side by side method.

As shown, the format of the 3D image according to the side-by-side scheme is a format including both the left eye image and the right eye image in one frame. Particularly, in the 3D image format according to the side-by-side method, the left eye image and the right eye image are divided into right and left, the left eye image is provided on the left side, and the right eye image is provided on the right side.

In this format, the TV 200 separates each frame of the received 3D image into left eye image parts and right eye image parts by bisecting the left and right frames, and separates the left eye image part and the right eye image part by two Scaled to generate a left eye image and a right eye image to be displayed on the screen, and the generated left eye image and right eye image are alternately displayed on the screen.

Accordingly, the 3D image is obtained by multiplying the left part L1 of the image included in the first frame by two times the left eye image, the right image R1 of the image included in the first frame by two times, > Left eye image which is enlarged twice the left part (L2) of the image included in the second frame -> Right eye image which is twice enlarged the right part (R2) of the image included in the second frame -> ... 'Will be displayed on the screen.

Meanwhile, although the process of processing the 3D image format according to the side-by-side scheme has been described above, it is needless to say that the processing process of the 3D image format according to the top-bottom scheme can also be deduced therefrom. That is, in the case of the 3D image format according to the top-bottom system, the TV 200 divides each frame of the received 3D image into upper and lower halves to divide them into a left eye image part and a right eye image part, And the left eye image and the right eye image to be displayed on the screen, and displays the generated left and right eye images alternately on the screen.

FIG. 5C shows a method of displaying a 3D image on a screen when the 3D image is received by the horizontal interleaving method.

As shown, the format of the 3D image according to the horizontal interleave method is a format including both the left eye image and the right eye image in one frame. In particular, the format of the 3D image according to the horizontal interleave method is a format in which the left eye image and the right eye image are alternately arranged in a row unit.

In this format, the TV 200 separates each frame of the received 3D image into a left eye image part and a right eye image part by dividing each frame by an odd row and an even row, and separates the left eye image part and the right eye image part from each other To generate a left eye image and a right eye image, and displays the generated left eye image and right eye image alternately on the screen.

Accordingly, the 3D image is divided into the right-side part (R1-R1) of the images included in the first frame, the left-eye image obtained by enlarging the odd row parts (L1-1, L1-2) of the images included in the first frame, 2 > in the left eye image- > the second frame in which the left parts L2-1 and L2-2 of the images included in the second frame are doubled, Right-eye images with two-fold magnification of the right-hand part (R2-1, R2-2) 'Will be displayed on the screen.

Of course, with respect to the format of the 3D image according to the horizontal interleave method, the left-eye image is generated by interpolating the even-numbered row portion using the odd-numbered row portion of the image included in one frame without using the enlargement scaling method described above, The right eye image may be generated by interpolating the odd row portion using the row portion.

In addition, it is also possible to implement a method of generating a left eye image by outputting an image for only odd rows and outputting an image for only even rows without using an enlargement scaling method or an interpolation method to generate a right eye image.

Although the process of processing the format of the 3D image according to the horizontal interleaving method has been described above as an example, the process of processing the format of the 3D image according to the vertical interleave method or the checkerboard method can also be deduced from the above .

That is, with respect to the format of the 3D image according to the vertical interleave method, the 3D image can be provided to the user by generating the left eye image and the right eye image by applying scaling or interpolation according to the column, not by line scaling or interpolation.

In addition, for the 3D image format according to the checkerboard method, pixel-by-pixel scaling or interpolation or pixel-by-pixel 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. Fig.

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

When the 3D image is received, the TV 200 automatically analyzes the format to be applied to the received 3D image, processes the 3D image according to the analyzed format, and displays it on the screen. For example, if the received 3D image is generated in a format according to the top-bottom scheme, the TV 200 uses the format information added to the received 3D image to determine a format to be applied to the received image .

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 the left and right eye images are scaled up and down to produce a left eye image and a right eye image, and the generated left eye image and right eye image are time-divisionally displayed alternately.

FIG. 6 shows a 3D object 610 in which a circular left eye image and a circular right eye image are overlapped with each other for graphical representation of a 3D image that is time-divisionally displayed alternately.

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

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

Accordingly, the user can change the output state of the 3D image, the item for changing the output order of the left eye image and the right eye image constituting the 3D image, the item for changing the format, It is possible to change the format of the 3D image, to convert the 3D image into the 2D image, to change the output order of the 3D image, or to convert the output state of the 3D image.

The format change means a change to a format according to one of a frame sequence system, a top-bottom system, a side-by-side system, a horizontal interleave system, a vertical interleave system and a checkerboard system.

The 2D method means a method of displaying the received 3D image in 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 and not displayed alternately, only the left eye images are displayed or only the right eye images are displayed. As a result, a 2D image in which the three-dimensional effect disappears 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 the left eye image -> right eye image, or output in the order of the right eye image -> the left eye image.

The output state means whether the 3D image is being output in the state that the 3D mode is ON or whether the 3D image is being output in the state where the 3D mode is OFF.

The fact that the 3D mode is turned ON means that each image frame included in the input 3D image is divided into a left eye image part and a right eye image part according to the applied format and the enlarged scaled left eye image part and right eye image part, And the left eye image and the right eye image 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. Accordingly, in this case, if the 3D image has a format other than the frame sequence format, the left eye image and the right eye image are simultaneously displayed.

On the other hand, color information for guiding the selection of each item is added as information on the buttons necessary for selecting each item, around the items included in the item set 630. [ The color information may be provided as shown in the text of R, G, Y, B, or may be displayed in actual color, as shown.

Accordingly, the user can transmit an instruction for format change to the TV 200 by pressing the R-button provided on the front panel of the TV 200 or the R-button provided on the remote control 400. [ When a command for format change is received, the GUI 620 for guiding various settings is changed to a GUI for format change.

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

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

When the 3D image is received, the GUI 620 that analyzes the format to be automatically applied to the 3D image and applies the same to guide various settings for the 3D image is displayed, It is possible to easily and easily change the various settings of the display device.

7A to 7D are diagrams showing screens in which an item included in the GUI is selected and the GUI is changed.

When the user presses the R-button provided on the TV 200 or the remote controller 400, the screen of Fig. 6 is switched to the screen of Fig. 7A. That is, when the R-button is pressed, the 3D object 610 is directly displayed on the screen, 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 frame sequence method, the top-bottom method, the side by side method, the horizontal interleave method, the vertical interleave method, and the checkerboard method. Items 640 representing formats in the illustrated example represent formats according to the top-bottom, side by side, horizontal interleave, vertical interleave, checkerboard, and frame sequence formats, respectively, from left to right .

Accordingly, 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 the top- The format is changed to the format according to the bi-side method, the horizontal interleave method, the vertical interleave method, the checker board method, and the frame sequence method, or vice versa.

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

On the other hand, in the GUI 640, information indicating that the format is changed state is displayed on the upper or lower side of the item 640 indicating the format, and items for guiding the user's manipulation, selection, And the format applied to the current 3D image can be highlighted.

When the user presses the G-button provided on the TV 200 or the remote controller 400, the screen of Fig. 6 is switched 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 corresponding to the 2D-type image is displayed on the screen.

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

At the lower end of the 2D object 650, information indicating that the current screen is a screen according to the 2D method is displayed so that the G-button is pressed to switch back to the 3D mode. In other words, this information guides the user to press the G-button to view an image according to the 3D method.

When the user presses the Y-button provided on the TV 200 or the remote controller 400, the screen of Fig. 6 is switched to the screen of Fig. 7C. That is, when the Y-button is pressed, the 3D object 610 disappears from the screen, and a screen in which the output order of the 3D image is changed is displayed. Accordingly, the 3D object 670 can have a different form from the object before the output order is changed.

Also, in the lower end of the 3D object 670, information that the current screen is displayed in the order of right eye image- > left eye image, and information for pressing the Y-button to switch back to the left eye image- > Is displayed. That is, this information is guided by the user to press the Y-button to view the displayed image in the order of the left eye image and the right eye image.

In addition, when the user presses the B-button provided on the TV 200 or the remote controller 400, the screen of FIG. 6 is switched 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 in a 3D mode off state, unlike an object displayed on the screen according to the 2D method.

That is, one of the objects included in the left eye image and the object included in the right eye image is not displayed, but each image frame included in the input 3D image is displayed as it is, and the 3D image is displayed in accordance with a method other than the frame sequence method Format, it means that both the object included in the left eye image and the object included in the right eye image are displayed.

Further, at the lower end of the 2D object 690, the information that the current 3D function is turned off and the B-button is pressed to turn on the 3D function is displayed. That is, this information guides the user to change the 3D mode OFF to the 3D mode ON state by pressing the B-button.

This makes it possible to change various settings of the 3D image more easily and easily.

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

It goes without saying that the user can also manually depress the GUI 620 by pressing a specific button such as the ENTER button.

<Operation flow for changing various settings of 3D image>

Hereinafter, an operation flow for changing various settings will be described with reference to FIG. 9 is a diagram for explaining a GUI providing method according to an embodiment of the present invention.

When the 3D image is received (S710-Y), the TV 200 creates a GUI for guiding various setting operations on the 3D image (S720). In addition, the TV 200 determines whether there is format information related to the received 3D image (S730).

If there is format information on the 3D image (S730-Y), the TV 200 extracts the format information, processes the 3D image according to the format based on the extracted format information, and displays the processed 3D image (S740).

In addition, the TV 200 adds a GUI to the displayed 3D image (S750). As described above, the GUI includes an item corresponding to the R-button, an item corresponding to the G-button, an item corresponding to the Y-button, and an item corresponding to the B-button.

Accordingly, if an item corresponding to the R-button is selected from the user (S760-Y), the TV 200 switches the existing GUI to a GUI for format change (S770). If a format change command is input from the user through the GUI for changing the format (S780-Y), the TV 200 processes the 3D image according to the changed format and displays it on the screen (S790) The highlight is moved to the item corresponding to the format (S800).

If the item corresponding to the G-button is selected from the user (S810-Y), the TV 200 processes the 3D image according to the 2D method and displays it on the screen (S820) (S830).

If an item corresponding to the Y-button is selected from the user (S840-Y), the TV 200 changes the order of the left eye image and the right eye image to be opposite to the order in which the current 3D image is output, S850) and switches the existing GUI to a GUI including information indicating that the order has been changed (S860).

In addition, when an item corresponding to the B-button is selected from the user (S870-Y), the TV 200 outputs the inputted 3D image as it is on the screen (S880), and notifies the existing GUI that the 3D mode is OFF And switches to a GUI including information (S890).

This also makes it possible to easily and easily change various setting items for the 3D image.
