Summary:A method for enhancing detail information in rasterized, continuous tone images includes a function that enlarges the contrast of a pixel in a neighborhood of pixels when in that neighborhood one of the pixels has a value that is close to a white color. This is determined by selecting the whitest pixel in the neighborhood. The function shows a gradual transition between the situations in which the whitest pixel is close to the white color and in which the whitest pixel is far from the white color. The method results in a better rendering of fine print when the image is sent to a printing system that reproduces the image on receiving material. For small characters, the legibility is improved by application of this method.
