Abstract:
A method for converting an input image in an input color space to an output image in an output color space, wherein said input image comprises a plurality of input pixels; said method comprises the steps of:storing, in a first memory, sparsely located output color values of said output color space;supplying a stream of neighbouring pixels of the input image; and performing the following steps on each pixel of the stream;storing, in a cache memory from said first memory, sparsely located output color values corresponding to the input pixels closest to the current input pixel of the stream, if not already present in the cache memory;retrieving, from said cache memory, sparsely located output color values corresponding to the input pixels closest to the current input pixel of the stream;interpolating the retrieved output color values to derive an output color value in said output color space.
