A method and apparatus for translating color to grayscale images, wherein
at least some pixels of the color image having the same color are mapped
to different grays in the grayscale image depending on the spatial
surround of each pixel. Further, the method and apparatus may include
applying a high pass filter to at least one chrominance component of a
color image to generate at least one high pass filtered chrominance
component, and adjusting a luminance component of the color image based
upon the at least one high pass filtered chrominance component.
