• means for selecting a pixel within a text image;
• means for determining a local minimum contrast and a maximum contrast in a radius of pixels from the selected pixel wherein the radius comprises at least two pixels;
• means for setting a first contrast measurement equal to the difference between the maximum contrast of a pixel in the radius of pixels from the minimum contrast of a pixel in the radius of pixels;
• means for determining if the first contrast measurement is equal to or greater than a threshold;
• if the first contrast measurement is equal to or greater than a threshold, means for calculating a first pixel value and a second pixel value;
• if the first contrast measurement is equal to or greater than a threshold, means for averaging the first pixel value and the second pixel value;
• and
• if the first contrast measurement is equal to or greater than a threshold, setting the contrast of the selected pixel to the average of the first pixel value and the second pixel value thereby enhancing the text image.
