Referring to FIG. 2 again, the A / V processor 130 may perform signal processing such as video decoding, video scaling, and audio decoding on video signals and audio signals input from the broadcast receiver 110 and the video input unit 120. Perform GUI creation.

On the other hand, when storing the input image and the audio signal in the storage unit 170, the A / V processing unit 130 compresses the input image and the audio in order to store the input voice and the image in a compressed form.

As shown in FIG. 2, the A / V processor 130 includes a voice processor 132, an image processor 134, and a 3D image implementer 136.

The voice processor 132 performs signal processing such as audio decoding on the input voice signal. The voice processor 132 outputs the processed voice signal to the voice output unit 140.

The image processor 134 performs signal processing such as video decoding and video scaling on the input image signal. When the 3D image data is input, the image processor 134 outputs the input 3D image data to the 3D image implementer 136.

The 3D image implementer 136 generates an interpolated left eye image and a right eye image using the input 3D image data. That is, the 3D image implementation unit 136 generates a left eye image and a right eye image to be displayed on a screen to implement a 3D stereoscopic image.

In detail, the 3D image implementing unit 136 separates left eye image data and right eye image data from the input 3D image data. Since the left eye image data and the right eye image data are included together in one frame data, the separated left eye image data and the right eye image data each have image data corresponding to half of the full screen size. Accordingly, the 3D image implementation unit 136 enlarges or interpolates the separated left eye image data and the right eye image data twice to generate a left eye image and a right eye image to be displayed on a screen having a size of one screen. The 3D image implementation unit 136 outputs the generated left eye image and the right eye image to the image output unit 150 to be alternately displayed.

The voice output unit 140 outputs the voice transmitted from the A / V processing unit 130 to a speaker or the like.

The image output unit 150 outputs the image transmitted from the A / V processing unit 130 to be displayed on the screen. In particular, in the case of a 3D image, the image output unit 150 alternately outputs a left eye image and a right eye image to the screen.

The storage unit 170 stores the image received from the broadcast receiving unit 110 or the image input unit 120. The storage unit 170 may be implemented as a hard disk, a nonvolatile memory, or the like.

The manipulation unit 180 receives a user's manipulation and transmits the manipulation to the controller 160. The manipulation unit 180 may be implemented as a remote controller, a pointing device, a touch pad, a touch screen, or the like.

The spectacles signal transceiver 195 transmits a clock signal for alternately opening the left eye glasses and the right eye glasses of the 3D glasses 190. The 3D glasses 190 alternately open the left eye glass and the right eye glass according to the received clock signal. In addition, the glasses signal transceiver 195 receives state information and the like from the 3D glasses 190.

The controller 160 identifies a user command based on the user's manipulation contents transmitted from the manipulation unit 180, and controls the overall operation of the TV according to the identified user command.

In addition, the controller 160 sets whether to automatically determine the 3D image format according to a user's manipulation received from the manipulation unit 180. That is, if the user is set to automatically determine the 3D image format input through the operation unit 180, the controller 160 controls to determine the format of the input 3D image automatically. If the user is set to not automatically determine the format of the 3D image input via the operation unit 180, the control unit 160 controls to select the format of the input 3D image via the operation unit 180.

In addition, if the format of the input 3D image is set to be automatically determined, the controller 160 analyzes the format of the input 3D image. Based on the analysis result, the controller 160 automatically determines a format of the 3D image corresponding to the format of the input 3D image. In addition, the controller 160 controls the 3D video format automatic determination message to be displayed on the image output unit 150. Here, the 3D video automatic determination message refers to a message that informs the screen that the 3D video is automatically determined.

In addition, if the format of the input 3D image is not determined automatically, the controller 160 controls the image output unit 150 to display a 3D image format manual selection menu. The manual selection menu of 3D video format refers to a menu for the user to select a format of 3D video. If the user selects one format from the 3D image format manual selection menu through the manipulation unit 180, the controller 160 controls to display the 3D image of the selected format.

In addition, when the execution command of the 3D image format manual selection menu is input through the operation unit 180 while the automatic determination of the format of the 3D image is set, the controller 160 controls to display the 3D image format manual selection menu. . If the 3D video format manual selection menu is executed even after the automatic judgment is set, the user may need to select a new format because the 3D video of the automatically determined format is not properly displayed.

Hereinafter, the 3D image conversion method in the 3D TV 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 5B.

4 is a flowchart illustrating a 3D image conversion method according to an embodiment of the present invention.

First, the 3D TV 100 sets whether to automatically determine the format of an input 3D image according to a user's operation (S410). The 3D TV 100 receives a 3D image (S420).

The 3D TV 100 determines whether to automatically determine the format of the input 3D image according to the setting result of step S410 (S430). If it is set to automatically determine the format of the input 3D image (S430-Y), the 3D TV 100 displays a 3D image format automatic determination message (S440).

The 3D TV 100 automatically determines the format of the input 3D image and displays the 3D image input in the determined format (S450). In detail, the 3D TV 100 analyzes a format of an input 3D image. In this case, the 3D TV 100 may analyze the format of the 3D image by using tag information included in the input 3D image or by comparing the left and right images of the input 3D image. Based on the analysis result, the 3D image implementation unit 136 generates a left eye image and a right eye image corresponding to the format of the input 3D image. The generated left eye image and the right eye image are alternately output through the image output unit 150, thereby displaying a 3D image.

If it is set not to automatically determine the format of the input 3D image (S430-N), the 3D TV 100 displays a 3D image format manual selection menu in order to manually select the 3D image format (S470). According to the user's operation, the input 3D image format is manually selected (S480). Based on the selection result, the 3D image implementation unit 136 generates a left eye image and a right eye image corresponding to the format of the input 3D image. The generated left eye image and the right eye image are alternately output through the image output unit 150, thereby displaying a 3D image on the 3D TV 100 (S490).

In addition, when automatically determining the 3D image format, it is determined whether to execute the 3D image format manual selection menu (S460). If the 3D video format manual selection menu is not executed because there is no user's operation (S460-N), the 3D TV 100 does not execute the 3D video format manual selection menu and continues 3D video of the currently automatically determined format. The display is performed (S490). Here, when the manual selection of the 3D image format menu is not executed, the 3D image of the format automatically determined by the user is well seen and does not require a separate operation.

However, even if the 3D video format manual selection menu is executed by the user's operation even after automatically determining the 3D video format, the 3D TV 100 executes the 3D video format manual selection menu and manually reformats the input 3D video. (S460-Y). In this case, when the manual selection menu of 3D image format is executed, the 3D image of the format automatically determined by the user is not easily seen, and thus, the user needs to select a new format.

Through the above-described process, the user can automatically determine or manually select the format of the input 3D image, so that the format of the 3D image can be found more easily and accurately.

Hereinafter, a 3D image conversion method in the 3D TV 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 5A and 5B.

FIG. 5A illustrates a process of automatically determining a format when an automatic determination of a 3D image format is set.

As illustrated in FIG. 5A, a 3D image having a vertical division method is input (510). The controller 160 first analyzes the format of the input 3D image. While the controller 160 analyzes the format of the 3D image, the 3D TV 100 displays a message indicating that the image is being automatically judged through the image output unit 150 (520).

When the controller 160 analyzes that the input image is a vertical division method, the 3D image implementation unit 136 generates a left eye image and a right eye image corresponding to the 3D image of the vertical division method. The image output unit 150 alternately displays the generated left eye image and the right eye image, and outputs a 3D image.

5B is a diagram illustrating a process of manually selecting a format when a manual selection of a 3D image format is set.

As illustrated in FIG. 5B, a 3D image having a vertical division method is input (540). The 3D TV 100 generates a 3D video format manual selection menu to allow the user to select the format of the input 3D video (550).

If a format of the input 3D image is manually selected by a user's manipulation, the 3D image implementation unit 136 generates a left eye image and a right eye image corresponding to the user's selection. For example, when the user selects a vertical division method, the 3D image implementation unit 136 generates a left eye image and a right eye image corresponding to the 3D image of the vertical division method. The image output unit 150 alternately displays the generated left eye image and the right eye image, and outputs a 3D image.
