Abstract
A monochrome display device easily and clearly distinguishes a multicolored character image from a multicolored background image by employing four gradations of monochrome. First and second monochrome gradations are assigned to any respective non-colored and colored elements of the background image and third and fourth monochrome gradations are assigned to any respective non-colored and colored elements of the character image to display a composite image of the background image and the character image.
