Abstract:
1. A method for converting an input image with a plurality of pixels to an output image using an N-dimensional conversion table with a plurality of nodes, the method comprising the steps of: providing an input image with a plurality of pixels; converting the input image to an output image using an N-dimensional conversion table with a plurality of cubes each having a plurality of nodes, the N-dimensional conversion table being composed of a plurality of at least four subsets of cubes having nodes with each subset containing color information adapted to be simultaneously obtained; storing odd-indexed nodes and even-indexed nodes respectively on separate memory components for each dimension of the conversion table; retrieving for each pixel a set of output color values corresponding to nodes adjacent to the pixel in the conversion table; and interpolating within each set of output color values to produce the output image; thereby expediting input image conversion using a single access of memory for interpolation of data points.
