ABSTRACT:
A method of converting a color image into a monochromatic image, includes converting the color image into a color space representing brightness values and attribute values of pixels constituting the color image, converting the color image into the monochromatic image based on the brightness values of the pixels, and modifying brightness values of pixels of the monochromatic image based on eigenvalues corresponding to the attribute values of the pixels of the color image.
