3D stereoscopic image technology has various applications such as information communication, broadcasting, medical, education and training, military, game, animation, virtual reality, CAD, industrial technology, etc. It is a core foundation technology of.

In general, the three-dimensional sense perceived by a person is caused by the degree of change in the thickness of the lens depending on the position of the object to be observed, the difference in angle between the two eyes and the object, the difference in the position and shape of the visible object in the left and right eyes, and the movement of the object. Lag and other effects such as various psychological and memory effects are produced in combination.

Among them, binocular disparity, which appears as the human eyes are positioned about 6 to 7 cm apart in the horizontal direction, can be said to be the most important factor of the three-dimensional effect. In other words, the binocular parallax makes us look at the angle with respect to the object, and because of this difference, the images coming into each eye have different images, and when these two images are transmitted to the brain through the retina, You can feel the original 3D stereoscopic image by fusion with each other exactly.

The 3D image display apparatus is classified into glasses type using special glasses and non-glass type not using special glasses.

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 display unit 150 to be alternately displayed.

Meanwhile, in order to generate a preview screen including a plurality of formats for the input 3D image, the 3D image implementation unit 136 generates a left eye image and a right eye image in a plurality of formats for the input 3D image data. The left eye image and the right eye image of the generated plurality of 3D images are output to the display unit 150 to be alternately displayed on one screen.

In addition, the controller 160 analyzes the format of the input 3D image data. In detail, the controller 160 analyzes the format of the input 3D image through the tag information included in the input 3D image data, or compares the format of the input 3D image by comparing the left eye image or the right eye image of the input 3D image. Analyze

Hereinafter, a method for providing 3D image preview in the 3D TV 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 6.

4 is a flowchart illustrating a method of providing a preview including a plurality of formats of 3D images for an input 3D image according to an embodiment of the present invention.

 The 3D TV 100 receives a 3D image at the broadcast receiving unit 110 or the image input unit 120 at step S410. While the 3D image is output, the 3D TV 100 receives a preview generation command through the manipulation unit 180 (S420). When the 3D TV 100 receives a preview generation command, the 3D image implementation unit 136 generates a left eye image and a right eye image of a plurality of formats for the input 3D image (S430). In this case, the 3D image implementation unit 136 alternately outputs the generated plurality of left eye images and the plurality of right eye images to the display unit 150.

The display unit 150 alternately displays the output left eye images and the plurality of right eye images (S440). Since the 3D TV 100 alternately displays the plurality of left eye images and the plurality of right eye images on one screen, the 3D images of the plurality of formats may be displayed on one screen in a preview format (S450).

In this case, an image that matches the format of the input 3D image among the 3D images of the plurality of formats is displayed separately from an image that does not match the format of the input 3D image. Since the 3D TV 100 displays the image that matches the input 3D image separately from the image that does not match, the user can select a format of the 3D image more easily and conveniently.

5 is a flowchart illustrating a method for selecting a format of a 3D image input through a 3D image preview according to an embodiment of the present invention.

Through the above-described process, the 3D TV 100 displays a preview of a 3D image of a plurality of formats (S510). The 3D TV 100 determines whether a user's selection is input through the operation unit 100 to select one of a plurality of formats (S520). If it is determined that the user's selection is input through the manipulation unit 180 (S520-Y), one of a plurality of formats is selected according to the user's selection.

When one of the plurality of formats is selected according to the user's selection, the 3D of the selected format among the 3D images of the plurality of formats is displayed only on the big screen and the remaining screens disappear.

In detail, when one format among a plurality of formats is selected by a user's manipulation, the 3D image implementing unit 138 generates only the left eye image and the right eye image of the selected format among the plurality of formats. The 3D image implementer 138 alternately outputs the generated left eye image and right eye image to the display unit 150. The display unit 150 alternately displays the left eye image and the right eye image generated by the 3D image implementor 138. Accordingly, the 3D image of the selected format is displayed on the display unit 150 as a 3D image of a large screen.

6 is a diagram illustrating a process of providing a preview of a 3D image in the 3D TV 100 and selecting one of the preview images according to an embodiment of the present invention.

The 3D image is input to the 3D TV 100 (610). For example, as shown in FIG. 6, 3D video of a vertical division method is input to the 3D TV 100.

When the 3D image is input to the 3D TV 100, as shown in FIG. 6, the 3D TV 100 generates and displays 3D images of a plurality of formats through the above-described process (620). For example, even when a 3D image of a vertical division method is input, a 3D image of a plurality of formats such as a left-right division method, a checker board method, a vertical interleaved method, a horizontal interleaved method, and the like is generated and displayed. In this case, the 3D TV 100 may analyze the format of the input 3D image and display the 3D image of the analyzed format separately from other images (625). For example, when the 3D image of the vertical division method is input, the 3D TV 100 analyzes the format of the input 3D image by the vertical division method. The 3D image generated and displayed by the vertical division method among the 3D images of the plurality of formats is displayed separately from the 3D image of other formats. By dividing and displaying in this manner, the user can select a format of the 3D video inputted more easily and conveniently.

When a 3D image of one format is selected through a user's manipulation, the 3D TV 100 displays one image among a plurality of formats of 3D images in large (630). For example, when the user selects the 3D image generated and displayed in the vertical division method through the manipulation unit 180, the 3D TV 100 displays the 3D image generated and displayed in the vertical division method on a large screen.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims.
