Abstract
A method and apparatus for producing output values corresponding to pixels of an input image. A coordinate translation circuit for is provided for performing coordinate translation from input pixel color components to corresponding texture coordinates. The texture coordinates collectively determine a texture address. The coordinate translation circuit also generates a set of interpolation factors in one embodiment used to resample around the point in texture space defined by the texture address. An interpolation circuit is coupled to the coordinate translation circuit to receive the texture address and the set of interpolation factors. The interpolation circuit uses the texture address and the set of interpolation factors to produce an output value. Typically, the output value represents a multidimensional lookup of the color components interpolated into multidimensional space. An application of the method and device of the invention includes a color conversion method for converting input pixel color components from a source color space to a destination color space.
