Problems solved by technology

GUI processing accompanying video zooming expands the field of view of the menu and maintains user convenience. Therefore, if the GUI processing accompanying zooming is omitted for the realization of stereoscopic vision, it means that the convenience of the current optical disc playback device Sexual regression, never a good idea for industry

no. 2 Embodiment approach ）

[0595] In this embodiment, a modified example will be described, that is, instead of making the flow of subtitle data and interactive graphics data follow the depth of the video stream as in the first embodiment, by making the video stream follow the depth of the subtitle / GUI, Thereby reducing eye fatigue of viewers caused by zooming in and out of subtitled videos.

[0596] In scaling, in order to make the positional relationship between the subtitles or graphics and the moving image not become strange, when performing the plane shift of the video plane, it is necessary to consider what value the plane offset of the graphics plane is to calculate the value for the video plane Plane offset.

[0597] In order to realize such a configuration, in the present embodiment, for example, a configuration is adopted in which the offset value of the image plane setting stored in the display mode storage unit 29 can be read and used for the offset of the video. , and assume that the plane...

no. 3 Embodiment approach ）

[0642] This embodiment is an extended example of the first embodiment. When scaling is performed, if the enlargement / reduction ratio is high, the change in depth is drastically different before and after scaling. In the first embodiment, when zooming is performed, the depth change corresponding to the zoom factor is reflected in the next frame after the zoom request. If the depth of the video is suddenly and drastically different, it will cause fatigue to the user's eyes. In this embodiment, a variation will be described in which the depth is not changed once in the next frame when there is a zoom request, but the depth is changed little by little for the purpose of reducing eye fatigue of the user.

[0643] In order to change the depth little by little, both the initial plane offset and the final plane offset need to be stored in the plane shift engine 20 as the plane offset, and the mid-stage plane offset needs to be calculated during the depth change process. shift. If t...

no. 4 Embodiment approach ）

[0706] The amount of shifting when the plane shifting engine 20 performs plane shifting needs to be calculated based on certain parameters for stereoscopic vision. In order to calculate this shift amount, it is preferable to use a plane offset for stereoscopic viewing included in an MVC (Multi View Codec) video stream as a parameter. However, the present invention is not limited thereto, and it is preferable that the content provider can provide the plane shift engine 20 with various information elements provided to the playback device via the BD-ROM.

[0707] refer to Figure 53 The setting process of the plane offset will be described.

[0708] Figure 53 Indicates the structure of the section related to the setting of the plane offset.

[0709] There are the following variations (AA) to (FF) in the method of providing the plane offset.

[0710] (AA) The BD-J application can update the plane offset of the plane setting in the display mode storage unit 29 by calling the m...

Abstract

The offset setting unit (21) holds an offset that indicates, using the number of pixels, how much the coordinates of the pixels should be moved to the right or left in order to achieve stereoscopic vision. When realizing stereoscopic vision, the plane shift engine (20) moves the respective coordinates of the pixel data in the graphics plane to one of the right direction and the left direction by the indicated number of pixels. When the size of video data that is a target of stereoscopic vision is changed from the basic graphics plane (15), the amount of movement of the pixel coordinates by the plane shift engine (20) is based on the above-mentioned offset multiplied by the change in the horizontal direction. The number of pixels obtained by the zoom ratio.

Description

technical field [0001] The present invention belongs to the technical field of stereoscopic vision reproduction. Background technique [0002] The so-called stereoscopic reproduction technology refers to a technology that introduces a mechanism that allows people to see different images in the left eye and right eye, and utilizes the parallax between the two eyes to virtually form a three-dimensional image. [0003] At present, among the applications of stereoscopic reproduction technology, the application in theaters and the like is the mainstream, but the utilization method of enjoying stereoscopic reproduction through home-installed monitors and reproduction devices is also expected to spread rapidly in the future. [0004] There are various types of displays (stereoscopic displays) for allowing users to view stereoscopic images. For example, as one of the frequently used methods, there is a method of using shutter glasses. In this method, the viewers' left and right ey...
