20110285735 | SYSTEM AND METHOD FOR COMPOSITING PATH COLOR IN PATH RENDERING - One embodiment of the present invention sets forth a technique for compositing a rendered path object into an image buffer. A shader program executing within a graphics processing unit (GPU) performs a stenciling operation for the path object and subsequently performs a texture barrier operation, which invalidates caches configured to store texture and frame buffer data within the GPU. The shader program then performs covering operation for the path object in which the shader renders color samples for the path object and composites the color samples into an image buffer. The shader program binds to the image buffer for access as both a texture map and a writeable image. Stencil values are reset when corresponding pixels are written once per path object, and texture caches are invalidated via the texture barrier operation, which is performed after each covering operation per path object. | 2011-11-24 |

20110285827 | IMAGE REPRODUCING APPARATUS AND IMAGE DISPLAY APPARATUS - An image display apparatus capable of connecting to an image reproducing apparatus, including: an authentication switchover unit operable to perform mutual authentication with the image reproducing apparatus to switch an own authentication state between a 2D-authenticated state and a 3D-authenticated state; a display switchover unit operable to switch an own display mode between a 3D display mode and a 2D display mode; and an output unit operable to output image display mode information in accordance with the display mode set in the own apparatus in case where the authentication switchover unit sets the own authentication state to the 3D-authenticated state. | 2011-11-24 |
20110285828 | USING 3D TECHNOLOGY TO PROVIDE MULTIPLE PERSPECTIVES IN SHOWS AND MOVIES - A system and method that uses 3D technology to provide multiple character viewpoints in shows and movies. An image source module provides multiple series of images. A processor module connected to the image source module receives the multiple series of images provided by the image source module to create multiple series of images each representing a different character's viewpoint. A single display module connected to the processor module to display the multiple series of images representing different character's viewpoints. A viewer restricted to viewing a single series of images representing one character's viewpoint from the multiple series of images displayed by the single display module. | 2011-11-24 |
20110285829 | IMAGE WATCHING GLASSES IDENTIFICATON DEVICE, IMAGE WATCHING SYSTEM, PAIR OF IMAGE WATCHING GLASSES, IMAGE WATCHING GLASSES IDENTIFICATION PROGRAM, COMPUTER-READABLE RECORDING MEDIUM, AND DISPLAY DEVICE - An image watching glasses identification device | 2011-11-24 |
20110285830 | Stereoscopic Image Display Apparatus Capable Of Wirelessly Transmitting and Receiving Power - Disclosed herein is a stereoscopic image display apparatus capable of wirelessly transmitting and receiving power. The stereoscopic image display apparatus includes a stereoscopic image display unit and shutter glasses. The stereoscopic image display unit divides stereoscopic images into images for the left eye and images for the right eye and displays the resulting stereoscopic images, generates a signal of opening/closing a right eye shutter and a left eye shutter, and generates a power signal and then wirelessly transmits power in a magnetic resonance coupling manner. The shutter glasses wirelessly receives the power signal from the stereoscopic image display unit in the magnetic resonance coupling manner, and provides the images for the left eye and the images for the right eye by alternatively opening and closing the left eye shutter and the right eye shutter in response to the signal of opening/closing the right eye shutter and the left eye shutter. | 2011-11-24 |
20110285831 | Content Playback Device, Content Playback Method, and Content Display System - A timing signal generation unit of a content playback device generates a shutter control signal requesting the opening or closing of a shutter of a lens among one or more lenses of a pair of shutter glasses worn by a user viewing a display panel adapted to display content, and a backlight control signal requesting a backlight of the display panel to be turned on at least when the shutter is open. A transmitter unit transmits the shutter control signal to the shutter glasses. The timing signal generation unit changes at least one of the timing of turning on the backlight or the timing of opening the shutter of the lens of the shutter glasses. | 2011-11-24 |
20110285832 | THREE DIMENSIONAL IMAGE DISPLAY DEVICE AND A METHOD OF DRIVING THE SAME - A three dimensional (3D) image display device including a display unit receiving a time-division configured 3D image, the time division configured 3D image including a plurality of two-dimensional (2D) images spaced apart over time; and a synchronization unit identifying first images in the plurality of 2D images to be viewed with a first viewer and second images in the plurality of 2D images to be viewed with a second viewer, and generating a synchronization signal based on the first and second images, wherein the display unit displays the plurality of 2D images on a full screen of the display unit. | 2011-11-24 |
