Patent number: 8493403Abstract: Color transformation sample point identification is described. A subset of points from a superset of points representing a colorimetric relationship is identified. The subset of points defines an initial n-simplex with (n+1) points representing an approximation of the colorimetric relationship, where n represents a number of dimensions. An additional point from the superset of points is selected and added to the subset of points to replace the n-simplex with a set of at least two n-simplices. The additional point is selected such that a volume of an (n+1)-simplex formed by the (n+1) points of the initial n-simplex and the additional point is increased. An error value for the approximation is determined by calculating an error volume between the (n+1)-simplex and the superset of points.Type: GrantFiled: September 4, 2009Date of Patent: July 23, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ingeborg Tastl, John Ludd Recker, Yao Zhang

Patent number: 8493619Abstract: Methods for mapping color data having at least one color associated therewith to an output device based on an input-device profile and an output-device profile, each profile having a tone curve and a color matrix, are provided. In one embodiment, the method includes receiving color data from an input device and determining whether the color data is in a linear space. If it is determined that the color data is not in a linear space, the method further includes applying the tone curve of the input device profile to the color data to convert it into a linear space. The method further includes converting the color(s) associated with the color data from the input linear space to an output linear space by applying the color matrix of the input device profile and the inverse color matrix of the output device profile to create color-converted image data.Type: GrantFiled: August 12, 2011Date of Patent: July 23, 2013Assignee: Microsoft CorporationInventors: Glenn F. Evans, Benjamin Ellett, David R. Blythe, Anantha R. Kancherla, Bradley P. Gibson, Michael D. Stokes, Steven James White, Denis Demandolx

Patent number: 8487949Abstract: The RGB values of each pixel in every frame are converted into ideal tristimulus values X, Y, and Z. Based on a chromaticity-histogram based on the tristimulus values X, Y, and Z and a color gamut for each Y value corrected in accordance with a backlight-brightness, an xy error count generation unit obtains the number of chromaticity errors for each of a plurality of backlight-brightnesses. A lightness-histogram is created based on the RGB signals for each frame. Based on the histogram and a lightness higher than a maximum tone after correction according to the backlight-brightness, a lightness error count generation unit obtains the number of lightness errors for each of the plurality of backlight-brightnesses. An error minimum BL-brightness detection unit decides an optimum backlight-brightness based on the number of chromaticity errors and the number of lightness errors. A tone conversion unit performs tone conversion in accordance with the backlight-brightness.Type: GrantFiled: June 17, 2009Date of Patent: July 16, 2013Assignee: Kabushiki Kaisha ToshibaInventor: Masami Morimoto

Patent number: 8482572Abstract: Display control means displays, on display means, an image based on first conversion target image data in which color information is set for each of a plurality of image elements. Coordinate determination means determines a first coordinate in accordance with an instruction performed by using the pointing device. Conversion target condition setting means obtains color information of an image element, in the first conversion target image data, which corresponds to the first coordinate, and sets a first conversion target condition in accordance with the obtained color information. Color conversion means performs color conversion processing of changing color information of an image element, in the first conversion target image data, which satisfies the first conversion target condition, and displays an after-conversion image on the display means.Type: GrantFiled: September 3, 2009Date of Patent: July 9, 2013Assignee: Nintendo Co., Ltd.Inventor: Naonori Ohnishi

Patent number: 8477371Abstract: What is disclosed is a novel system and method for generating a color lookup table (LUT) that minimizes interpolation errors over the entire color space, including the off-grid colors. The present method for LUT optimization considers off-grid point errors in assigning entries to the LUT. As described herein further, grid point values are computed that provide a least mean square error solution for the entire printer gamut volume. The present method dramatically reduces errors near the gamut boundary and can be used for populating nodes of any LUT that will be linearly interpolated, not only a table mapping from L*a*b* to CMYK.Type: GrantFiled: April 29, 2010Date of Patent: July 2, 2013Assignee: Xerox CorporationInventors: Zhigang Fan, Martin S.
