[0058] figure 1 It is a diagram showing usage behavior of recording media and playback devices. As shown in the figure, a BD-ROM 100 as an example of a recording medium and a playback device 200 constitute a home theater system together with a remote controller 300, a television 400, and liquid crystal glasses 500, and are used by users.

[0059] BD-ROM 100 provides, for example, movie works to the above-mentioned home theater system.

[0060] The playback device 200 is connected to the TV 400 to play back the BD-ROM 100 .

[0061] The remote controller 300 is a device that accepts the user's operations on the layered GUI. In order to accept these operations, the remote controller 300 has a menu key for calling a menu constituting the GUI, an arrow key for moving a cursor of a GUI component constituting the menu, The GUI components of the menu are an enter key for performing a final operation, a return key for returning a layered menu to a higher level, and a num...

Here, in the L image, an area adjacent to the non-pixel area L1 is referred to as an adjacent area L4. Similarly, in the R image, a region adjacent to the non-pixel region R1 is defined as an adjacent region R4.

[0249] Next, a modified example in which a part of the area related to the background plane is replaced with an area specified by the application will be described.

[0250] In this case, the information of the specified area is recorded in the BD-J application provided by the virtual file system 25 and executed in the BD-J module. The BD-J application designates an area to be used for blank rendering processing through the rendering engine 22b.

Abstract

Disclosed is a reproduction device (200) that performs stereoscopic reproduction by alternately reproducing a left view and a right view, and that is equipped with: a plane memory (6c) that stores image data comprising a prescribed number of vertical pixels x a prescribed number of horizontal pixels of pixel data; a shift engine (9b) that performs a shift process with respect to the plane memory for the left eye during the left view reproduction period, obtaining an image for the left eye which is shifted in one direction either to the right or to the left, and performs a shift process with respect to the plane memory for the right eye during the right view reproduction period, obtaining an image for the right eye which is shifted in the direction opposite that of the aforementioned one direction; and a rendering engine (22b) that, for the left-eye image and the right-eye image, performs a rendering process whereby substitute images generated from substitute pixel data of an opaque color are drawn in rectangular areas at the edges in the respective opposite directions of the shifting directions of those images.

Description

technical field [0001] The present invention relates to a technique for stereoscopically reproducing video content, especially a background (still: still) image. Background technique [0002] In recent years, the popularity of Blu-ray Disc (Blu-ray Disc, hereinafter referred to as "BD"), which is a next-generation optical disc standard, is accelerating. In a playback device conforming to the BD-ROM standard, subtitles and graphics are superimposed on a high-quality video stream, and output to a display device such as a monitor connected to the playback device, thereby enabling viewing of a highly immersive video (For example, refer to Patent Document 1). [0003] On the other hand, as a technical trend of display devices, stereoscopic displays that can enjoy not only flat images but also images that seem to fly out are becoming popular. There are various methods of stereo vision display, but the basic principle is to introduce the mechanism of using the left view and right...
