20110164113 | Conversion of Interleaved Data Sets, Including Chroma Correction and/or Correction of Checkerboard Interleaved Formatted 3D Images - Conversion of interleaved data and/or correction of color samples or other data are corrected by recognizing an underlying arrangement or format of different data sets within a data stream and a conversion process applied that causes bleeding between the sets. The data sets are, for example, separate channel views of a 3D display, and the corruption occurs, for example, upon up-conversion of color samples that take into account both views together rather than individually. The invention is embodied, for example, as part of a playback device, display, or as a stand alone converter box that corrects the corrupted samples by at least one of substitution, filtering, or interpolation with appropriately selected samples (e.g., neighboring samples of a same view). | 07-07-2011 |
20110170792 | Encoding and Decoding Architecture of Checkerboard Multiplexed Image Data - A device includes a coder or a codec configured for interleaved image data utilizing diamond shaped blocks for motion estimation and/or motion compensation and utilizing square or orthogonal transforms of residual data. In various embodiments, the decoder may be configured, among others, to perform de-blocking on edges of the diamond shaped blocks and/or data padding at boundaries of the image data. Additionally a method is proposed in which at least one of a transform and quantization process to be applied to de-multiplexed data is modified. One application is to combine left and right stereoscopic images, interleaved in a checkerboard manner. | 07-14-2011 |
20110254921 | Reconstruction of De-Interleaved Views, Using Adaptive Interpolation Based on Disparity Between the Views for Up-Sampling - Method for reconstructing interleaved views of a 3D image comprising the steps of: receiving interleaved views of a 3D image, de-interleaving said interleaved views into a first view and a second view, each de-interleaved view comprising missing pixels, at each pixel location determining an amount of disparity between said first and second views, for each view interpolating each missing pixel based on the amount of disparity determined at the associated pixel location, wherein when the determined disparity is above a predetermined disparity threshold, the missing pixel value is interpolated from the data of the view to be interpolated only (i.e. the view comprising said missing pixel value), and when the determined disparity is at or below said predetermined disparity threshold, the missing pixel value is interpolated from the data of both views. | 10-20-2011 |
20110280300 | Methods and Devices for Sub-Sampling and Interleaving Multiple Images, EG Stereoscopic - Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats. | 11-17-2011 |
