20100074594 | STEREOSCOPIC VIDEO PLAYBACK DEVICE AND STEREOSCOPIC VIDEO DISPLAY DEVICE - A video plane generation unit decodes stream data into a pair of left-view and right-view video planes, and outputs the pair alternately in a 3D display mode and either of the pair repeatedly in a pseudo 2D display mode. An image plane generation unit generates a pair of left-view and right-view image planes having an OSD at different horizontal locations according to its depth to be perceived, and alternately output the pair of image planes. A pseudo 2D display control unit instructs the video plane generation unit to operate in the 3D display mode and the pseudo 2D display mode in periods where the image plane generation unit does not and does output the image planes, respectively. The adder unit combines a video plane and an image plane generated by the video plane generation unit and the image plane generation unit, respectively, onto a frame, and outputs the frame. | 03-25-2010 |

20100150529 | PLAYBACK DEVICE, PLAYBACK METHOD, PLAYBACK PROGRAM, AND INTEGRATED CIRCUIT - The reading unit reads an application program, image data, a video stream, and an application management file from a recording medium. The virtual machine unit executes the application program. The memory unit includes an image data area for storing the image data. The playback unit plays back video data with use of the image data and the video stream in accordance with the application program. The management unit, in accordance with the application management file, instructs the virtual machine unit to start and terminate the application program and instructs the memory unit to change the image data area. Before instructing the memory unit to change the image data area, the management unit causes the virtual machine unit to forcibly terminate the application program even when the application management file specifies the continuous execution of the application program. | 06-17-2010 |
20100226628 | PLAYBACK DEVICE, PLAYBACK METHOD AND PROGRAM - A playback time axis of a video stream is composed of a plurality of frame periods. To overlay a rendered image with a stereoscopic video image to be displayed in the i-th frame period, a process of writing to a left-view plan memory and a process of writing to a right-view plane memory both need to be completed before the start of the i-th frame period. To simultaneously request the two rendering processes, the argument of an application interface includes a pair of specifications, one specifying writing to the left-view plane memory and the other specifying writing to the right-view plane memory. | 09-09-2010 |

20110063512 | SYNTHESIS DEVICE AND SYNTHESIS METHOD - In synthesizing live-action video and CG, when live-action video is shot by a moving camera, generation of CG that moves in accordance with the move of the live-action video without causing visual discomfort required a difficult operation such as programming in advance to precisely adjust the display timing and the display position of the CG. The present invention is to generate CG in accordance with live-action video shot by a moving camera with minimum visual discomfort, thereby creating a highly realistic synthesized video image. | 03-17-2011 |
20110080462 | PLAYBACK DEVICE, INTEGRATED CIRCUIT, PLAYBACK METHOD, AND PROGRAM FOR STEREOSCOPIC VIDEO PLAYBACK - Inconsistency between a left-view video image and a right-view video image possibly occurs in a playback device having a function of switching between a monoscopic playback mode for monoscopically playing back video images and a stereoscopic playback mode for stereoscopically playing back video images. The present invention aims to prevent such inconsistency when switching from the monoscopic playback mode to the stereoscopic playback mode. Specifically, the present invention prevents the inconsistency by invalidating a rendering request which is Graphics#drawImage, copying a content stored in the left-view graphics plane to a right-view graphics plane, switching a graphics plane setting after the copying, and then removing prohibition of a rendering request which is StereoGraphics#drawImage. | 04-07-2011 |
20110211815 | REPRODUCTION DEVICE, REPRODUCTION METHOD, AND PROGRAM FOR STEROSCOPIC REPRODUCTION - In performing stereoscopic view, a shift information memory stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realize stereoscopic view. When realizing stereoscopic view, a plane shift engine moves the coordinates of image data in a graphics plane in the right direction or the left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane, a shift distance of pixel coordinates by the plane shift engine is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction. | 09-01-2011 |
