20100091050 | Hierarchical Multicolor Primaries Temporal Multiplexing System - This invention describes an apparatus, methods and a system for high speed hierarchical multiplexing the native color primaries of SSL-based display systems in order to improve color quality and stability as well as brightness and the efficiency of the display system. | 04-15-2010 |
20120069022 | COLOR SEAMLESSNESS ACROSS TILED MULTI-PROJECTOR DISPLAYS - A method includes generating in a computer a representation for the color transfer function both direct and inverse, of a nonideal source device to those in a target device significantly different than the source device, using higher-dimensional Bezier patches by using a non-linear parameterization of the Bezier patches in the XYZ space for converting the RGB colors in the source device. The method is illustrated in an application for processing spatial variation in luminance and chrominance in a multiple projector display, which include the steps of balancing per projector white point, morphing per pixel chrominance gamut, constraining per pixel perceptual luminance; and smoothing per pixel Bezier based luminance. | 03-22-2012 |
20120098937 | Markerless Geometric Registration Of Multiple Projectors On Extruded Surfaces Using An Uncalibrated Camera - A method for registering multiple projectors on a vertically extruded three dimensional display surface with a known aspect ratio includes recovering both the camera parameters and the three dimensional shape of the surface from a single image of the display surface from an uncalibrated camera, capturing images from the projectors to relate the projector coordinates with the display surface points, and segmenting parts of the image for each projector to register the projectors to create a seamlessly wall-paper projection on the display surface using a representation between the projector coordinates with display surface points using a rational Bezier patch. A method for performing a deterministic geometric auto-calibration to find intrinsic and extrinsic parameters of each projector is included. | 04-26-2012 |
20120319997 | SCALABLE DISTRIBUTED/COOPERATIVE/COLLABORATIVE PARADIGM FOR MULTI-USER INTERACTION WITH PROJECTION-BASED DISPLAY WALLS - A method of distributed/cooperative/collaborative gesture management may comprise queuing actions of gestures as the gestures move across a display, processing the actions of each of the gestures by a projector in which the projector's display is close to a gesture, sending an anticipatory action message that one of the gestures is predicted to enter a display region of a projector, processing the actions of one of the gestures by a projector in which the projector's display is close to the one of the gestures, and in response to the one of the gestures being in an overlapping display projected by overlapping projectors, the actions of the one of the gestures are processed by the overlapping projector with the smallest identifier. | 12-20-2012 |
20120320200 | VIDEO FRAME SYNCHRONIZATION FOR A FEDERATION OF PROJECTORS USING CAMERA FEEDBACK - A method of audio and video synchronization may include capturing an image by each of a plurality of cameras. The images and audio may be compared with each other for synchronization. | 12-20-2012 |
20130070094 | AUTOMATIC REGISTRATION OF MULTI-PROJECTOR DOME IMAGES - Automatic registration of projectors and their images on a curved surface may be performed using non-linear optimization techniques. A camera may capture images on the curved surface. The camera may be un-calibrated. The camera parameters may be estimated using a non-linear optimization of data in the images of the curved surface. The images may be from multiple projectors. In some embodiments, registration may be view independent. | 03-21-2013 |
20130076789 | AUGMENTED REALITY USING PROJECTOR-CAMERA ENABLED DEVICES - An augmented reality scene may be registered onto an arbitrary surface. A camera may capture an image of the arbitrary surface. The camera may analyze the surface geometry of the arbitrary surface. In some embodiments, a processing computing device may analyze data captured by the camera and an adjacent camera to reconstruct the surface geometry of the arbitrary surface. A scene may be registered to a three dimensional coordinate system corresponding to the arbitrary surface. A projector may project the scene onto the arbitrary surface according to the registration so that the scene may not display as being distorted. | 03-28-2013 |
20140035919 | PROJECTOR WITH ENHANCED RESOLUTION VIA OPTICAL PIXEL SHARING - A projector configured to provide higher resolution output without increasing pixel resolution in a light modulator is disclosed. The projector may introduce an optical element between a light modulator and an imaging lens. The optical element may provide pixel sharing of a target image. The pixel sharing may be produced by, for example, making smaller copies of pixels. Selected copies of pixels may be passed to the imaging lens to display an output image with selected areas of higher density pixels. | 02-06-2014 |
