Abstract:
1. A method for providing a lookup table (LUT) for changing color components of pixels of an image, the method comprising: generating, via a computing device, an integer number, the integer number greater than or equal to one, of two-dimensional slices from a three-dimensional LUT, wherein the integer number of two-dimensional slices are arranged in order from a first two-dimensional slice to a last-numbered two-dimensional slice of the integer number of two-dimensional slices; generating, via the computing device, another integer number, the other integer number greater or equal to one, of upsampled slices corresponding to the integer number of two-dimensional slices, wherein the other integer number of upsampled slices are arranged in order from a first upsampled slice to a last-numbered upsampled slice of the other integer number of upsampled slices; forming, via the computing device, a first group of slices comprising the other integer number of upsampled slices; forming, via the computing device, a second group of slices comprising a second two-dimensional slice of the integer number of two-dimensional slices through the last-numbered two-dimensional slice and a copy of the last-numbered two-dimensional slice; and storing, via the computing device, the first group of slices and the second group of slices, respectively, in a zero level of a mip map and a first level of the mip map.
