VARIABLE POINT INTERPOLATION APPARATUS AND METHOD WITH SCALABLE ARCHITECTURE FOR COLOR CORRECTION

A variable point interpolation apparatus with scalable architecture for color correction and a method of the same are disclosed. The color correction apparatus is capable of transforming color image data from a first color space to a second color space and comprises: an appearance equivalent scalable computing means for analyzing the color characteristic of the image data from the first color space and dividing an interpolation input signal of the image data into upper bits and lower bits in which numbers of the upper bits and the lower bits are adjustable; a fuzzy variable point interpolation computing means for determining automatically a proper number of interpolation reference points; a non-uniform three-dimensional look-up table, wherein variations of distances between any two reference values of knot points in the non-uniform three-dimensional look-up table are non-uniform.
