Abstract
In a color converting device for converting input image data based on a plurality of first color components (the number of bits of each color component is k) into output image data based on plural of second color components by interpolation processing using a 3DLUT storing color correction values at grid points obtained by dividing a color space composed of the plurality of first color components, the distance of the grid points is 2(where n is an integer smaller than k), the number Dn of grid points of the plurality of first color components is an integer satisfying 2+1<Dn<2+1 (where Dn≠2+1, and m=k−n), and input image data is converted into output image data by converting each color component data of the input image data according to the number of grid points, and performing interpolation processing by reading color correction values corresponding to the converted color components from the 3DLUT.
