Conversion of interleaved data sets, including chroma correction and/or correction of checkerboard interleaved formatted 3D images

摘要

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).

主权项

1. A method, comprising the step of correcting a sample error in at least one pixel of a first image in a video stream, wherein the video stream comprises a checkerboard arrangement of two views of 3D video content, said video stream comprising a first colorspace and the sample error comprises color bleeding from a pixel of a second image in the video stream, wherein the color bleeding comprises bleeding induced by an up-conversion of a frame containing the first image and the second image, the method comprising:
performing a color conversion to a second colorspace; applying a correction schema by which at least one incorrect color sample in the first image is replaced by a replacement color sample derived from at least one correct color sample of the same image; wherein the correction schema comprises a schema retrieved from a database of schemas; and wherein the step of correcting comprises substituting an incorrect color sample in the first image by a correct neighboring color sample of the same image.
