Patent number: 12231122Abstract: A device applies a pre-function w=P(x) to an input signal x to obtain a first result w and applies a LUT to the first result w, wherein the LUT represents a main function ƒw(w) defined for a second grid of values Gw such that the pre-function P(x) is piecewise defined on a first grid Gx of signal values, where Gw=P(Gx). The device can further obtain the pre-function P(x), piecewise defined on the first grid Gx of the signal x and calculate the LUT with the second grid Gw=P(Gx). The piecewise pre-function P(x) can be obtained from a second pre-function Q(x) by applying Q(x) to signal values x to calculate the second grid Gw=Q(Gx) and defining the pre-function P(x) piecewise on the first grid Gx by linear interpolation of the values of the second grid Gw such that P(Gx)=Q(Gx).Type: GrantFiled: September 6, 2021Date of Patent: February 18, 2025Assignee: InterDigital CE Patent Holdings, SASInventors: Jurgen Stauder, Angelo Mazzante, Marie-Jean Colaitis, Patrick Morvan

Patent number: 11671550Abstract: The present principles relate to a method and device for gamut mapping from a first color gamut towards a second color gamut. The method comprises obtaining a preserved key color (prsv_colorK0) and a hue alignment angle (?K0) of the key color (colorK0) for each key color (colorK0) of at least 3 key colors to define a preserved gamut and a rotated gamut; and performing a hue mapping of a current color (color) from the first color gamut towards the second color gamut wherein in case the current color (color) is in a preserved gamut defined by the preserved key color (prsv_colorK0), the hue mapped current color is unchanged, and in case the current color is out of the preserved gamut, the hue mapped current color is calculated from the hue alignment angle (?K0) of two adjacent key colors of the current color (rotated gamut) and from the preserved area.Type: GrantFiled: October 25, 2021Date of Patent: June 6, 2023Assignee: INTERDIGITAL VC HOLDINGS, INC.Inventors: Cedric Thebault, Jonathan Kervec, Angelo Mazzante

Patent number: 11263731Abstract: The present principles relate to a method and device for gamut mapping from a first color gamut towards a second color gamut. The method comprises, in a plane of constant hue, obtaining a target lightness for a color on the boundary of first gamut with maximum chroma, called first cusp color; and lightness mapping of the color from the first color gamut towards the second color gamut wherein the lightness mapped color is calculated from a parabolic function applied to the color, the parabolic function mapping the first cusp color to a color having the target lightness. According to a particular characteristic, a preserved chroma is also obtained; and in case the chroma of the color is lower than or equal to the preserved chroma, the lightness mapped color is the color, and in case the chroma of the color is higher than the preserved chroma, the lightness mapped color is calculated from the parabolic function applied to the color.Type: GrantFiled: April 17, 2018Date of Patent: March 1, 2022Assignee: INTERDIGITAL VC HOLDINGS, INC.Inventors: Cedric Thebault, Marie-Jean Colaitis, Angelo Mazzante

Patent number: 8655802Abstract: After a first start-up, a first appliance performs a self-learning step for generating usage parameters. These parameters are elaborated on subsequent start-ups. When these parameters are optimized, the first appliance transmits them to another appliance which requests them. This second appliance uses the parameters of the first as optimized parameters. In this way, the second appliance limits the duration of the self-learning step and the use of non-optimal parameters. According to a refinement, the optimal parameters are centralized on a server which transmits them to a plurality of second appliances using a transmission network. The present invention also relates to an appliance and a server implementing the method.Type: GrantFiled: October 30, 2007Date of Patent: February 18, 2014Assignee: Thomson LicensingInventors: Philippe Mace, Luc Roux, Angelo Mazzante
