20080252657 | Color conversion circuit and method of color conversion using interpolation from conversion coefficients some of which are substituted - Exemplary embodiments of color conversion circuits and color conversion methods convert input color data into output color data. The input color data is positioned in a three-dimensional color space, which is divided into a plurality of unit cubes each having a fixed dimension. The input color data is converted by performing interpolations using conversion coefficients at vertexes of the unit cube within which the input color data is positioned. When the input color data is positioned on a gray axis of the color space, a substitution circuit substitutes some of the conversion coefficients such that the interpolation becomes a linear interpolation. As a result, it is assured that input color data positioned on the gray axis is converted to gray output color data. | 10-16-2008 |
