At this time, the configuration and operation of the present invention shown in the drawings and described by it will be described as at least one embodiment, by which the technical spirit of the present invention and its core configuration and operation is not limited.

The terms used in the present invention have been selected as general terms widely used as possible in consideration of the functions in the present invention, but may vary according to the intention or custom of a person skilled in the art or the emergence of a new technology. In addition, in certain cases, there is also a term arbitrarily selected by the applicant, in which case the meaning will be described in detail in the description of the invention. Therefore, it is intended that the terms used in the present invention should be defined based on the meanings of the terms and the general contents of the present invention rather than the names of the simple terms.

An object of the present invention is to provide a method for displaying a 3D image and a video display device according to the present invention which can adjust screen depth according to genre of a 3D image signal in consideration of a user's preference.

Hereinafter, in describing the technical idea of the present invention, for convenience of description, an image display apparatus capable of processing a 3D image, which is a 3D image, sequentially displays a left image and a right image, for example. Will be explained.

In connection with the present invention, the following briefly describes the three-dimensional image.

Three-dimensional images include stereo (or stereoscopic) images considering two viewpoints and multi-view images considering three or more viewpoints. The stereo image refers to a pair of left and right images obtained by photographing the same subject with a left camera and a right camera spaced apart from each other by a certain distance. The multi-view image refers to three or more images obtained by photographing the same subject with three or more cameras having a constant distance or angle.

The stereo video transmission formats include a single video stream format and a multi video stream format.

Single video stream formats include side by side, top / down, interlaced, frame sequential, checker board, or anaglyph. Etc. For example, in the side-by-side format, one sub-sampling of the left image and the right image in the horizontal direction is performed, and the sampled left image is placed on the left side and the sampled right image is placed on the right side. Make a video.

The multi video stream format includes full left / right, full left / half right, or 2D video / depth.

Stereo images or multi-view images are compressed and encoded by MPEG or various methods and transmitted to a receiving system. Here, the receiving system is an image display device capable of processing and displaying a three-dimensional image signal.

For example, a stereo image such as a side by side format, a top / down format, an interlaced format, a checker board, and the like may be compressed and transmitted by H.264 / AVC. In this case, a 3D image may be obtained by decoding the stereo image in the inverse of the H.264 / AVC coding scheme in the reception system.

In addition, one of a left image or a multiview image of a full left / half right format is assigned to a base layer image, and the other image is assigned to an enhanced layer image, and then the base layer image is mono. Encoding is performed in the same manner as the scopic video, and an upper layer video may be encoded and transmitted only with respect to correlation information between a base layer and an upper layer.

As an example of the compression encoding scheme for the image of the base layer, a JPEG, MPEG-1, MPEG-2, MPEG-4, H.264 / AVC scheme may be used. In addition, a compression encoding scheme for an upper layer video may use a H.264 / MVC (Multi-view Video Coding) scheme. In this case, the stereo image is allocated to the base layer image and one higher layer image, but the multiview image is allocated to the base layer image and the plurality of higher layer images. Here, a criterion for dividing a multiview image into an image of a base layer and an image of one or more higher layers may be determined according to the position of the camera or may be determined according to the arrangement of the cameras. Or may be arbitrarily determined without following special criteria.

In general, a 3D image (or 3D image) is based on a stereo vision principle of two eyes. The binocular parallax is an important factor in making the stereoscopic sense, and when the planar image of the left and right eyes are respectively connected, the brain can fuse these two different images to reproduce the depth and reality of the 3D image. Here, binocular disparity refers to the disparity of two eyes, and means the difference between the left and right eyes visible according to the distance between the two eyes that are about 65mm apart. For example, in a stereo image, an interval between a left camera and a right camera photographing the same subject may be parallax.

The 3D image display is largely divided into a stereoscopic method, a volumetric method, and a holographic method. For example, an image display device capable of displaying a 3D video signal using stereoscopic technology adds depth information to a 2D image, and the viewer can feel stereoscopic liveness and reality using the depth information. One such device is a set-top box or a digital broadcast receiver such as a digital television.

In addition, a method of displaying a 3D image includes a method of wearing glasses and a glasses-free method of not wearing glasses. The way of wearing the glasses is divided into passive and active methods.

In this case, the passive method distinguishes between the left image and the right image using a polarization filter. In other words, the passive method is to wear blue and red sunglasses on both eyes. The active method distinguishes left and right eyes using a liquid crystal shutter, and distinguishes between a left image and a right image by sequentially covering the left eye (left eye) and the right eye (right eye) in time. That is, the active method is a method of wearing and viewing glasses with an electronic shutter that is periodically repeated and synchronized with the time-divided screen, and may also be referred to as a time split type or shuttered glass method. Hereinafter, the glasses driven by the shuttered glass method are referred to as shutter glasses.

Representative examples of glasses-free glasses-free methods include a lenticular method in which a lenticular lens plate in which a cylindrical lens array is arranged vertically is installed in front of the image panel, and a barrier layer having a periodic slit on the image panel. There is a parallax barrier (parallax barrier) method having a.

In the following specification, in order to more easily describe the technical idea of the present invention, a stereoscopic method of a stereoscopic display method is taken as an example, and an active method of the stereoscopic method is described as an example. However, hereinafter, the shutter glasses will be described as an example of the active type media, but the present invention is not limited thereto, and the present invention can be applied to other media as described below.

As described above, in the case of the active method, when the image for the left eye is displayed through the image display device, the left shutter of the shutter glasses is opened, and the image for the right eye is displayed through the image display device. In this case, open the right shutter.

Can be.

In addition, it is monitored whether the genre of the 3D image signal to be displayed is changed (step 420). Monitoring in step 420 may be repeatedly performed at a predetermined time interval. In addition, the predetermined time interval may be differently adjusted according to the self setting of the image display apparatus 100 or the setting of the user.

Based on the monitoring result of step 420, it is determined whether the genre has changed (step 430).

If the genre has changed, the screen depth of the 3D image signal having the changed genre is adjusted according to the screen depth information for each genre stored in step 330 (step 460).

Here, operation 350 may further include determining whether screen depth information for each genre corresponding to the changed genre is stored (operation 440). Accordingly, step 460 may include adjusting the screen depth of the 3D image according to the changed genre when the screen depth information for each genre corresponding to the changed genre is stored.

As a result of the determination in step 440, if the genre screen depth information corresponding to the changed genre is not stored, the screen depth for each genre corresponding to the changed genre is set and stored (step 450). Here, step 450 is the same as step 320 and step 330.

For example, when a user manipulates a remote controller or the like and requests a channel change from a channel displaying a drama program to a channel relaying a sports program, and the genre is a drama, the stored screen depth is d1. For example, if the genre is sports, screen depth information is not stored. Then, at the time of requesting the channel change, steps 320 and 330 are performed to input and store screen depth information in the case of sports as a d2 value. Accordingly, the sports program can be relayed by adjusting the screen depth to d2 according to the stored screen depth information.
