Patent number: 9837013Abstract: Aspects of the present invention are related to systems and methods for compressing display non-uniformity correction data and for using compressed display non-uniformity correction data. A correction image may be compressed by fitting a data model to the correction image data and encoding the model parameter values. A correction image may be decomposed into two images: an image containing the vertically and horizontally aligned structures of the correction image and a smoothly varying image. The smoothly varying image may be compressed by fitting a data model to the smoothly varying image data. Multiple correction images may be compressed by determining eigenvectors which describe the distribution of the multiple correction images. Projection coefficients may be determined by projecting each correction image the determined eigenvectors, and an eigen-image associated with an eigenvector may be compressed. Correction data for a display may be reconstructed from parameter values stored on a display system.Type: GrantFiled: July 9, 2008Date of Patent: December 5, 2017Assignee: Sharp Laboratories of America, Inc.Inventors: Yeping Su, Xiao-Fan Feng, Hao Pan, Yasuo Ozawa

Publication number: 20170211226Abstract: The present invention provides a method of manufacturing a highly functional surface-modified fibrous material with high added value, to which a novel functionality is imparted while making use of the characteristics inherent in the fibrous material, by modifying the surface of a natural fibrous material derived from an animal or a plant, or of a synthetic fiber; and a surface-modified fibrous material thereby obtained. The method of manufacturing a surface-modified fibrous material according to the invention includes attaching an inorganic material on the surface of a fibrous material by a sol-gel reaction, while allowing the fibrous material to move via an air stream. Preferably, an atmospheric-pressure low-temperature plasma is further applied to the surface of the fibrous material on the surface of which the inorganic material has been attached, while allowing the fibrous material to move via an air stream.Type: ApplicationFiled: July 16, 2015Publication date: July 27, 2017Applicant: SILK WAVE SANGYO CO., LTDInventors: Yasuo OZAWA, Shinichi KURODA, Katsuhiko HOSOI, Tsunenori OZAWA
