ABSTRACT:
A simple color separation apparatus includes a light source for radiating light on the document, a movable color filter set arrayed in parallel with the main-scanning direction, the movable color filter set includes filters selectively transmitting colors respectively, which separate into three colors the radiated light reflected from the document, wherein each filter has sufficient length to cover the light in the main-scanning direction and a width that prevents interference between colors of the reflected and separated light; a lens for image-forming the light transmitted by each filter of the color filter set; a three-line CCD sensor for converting the light image formed by the image-forming lens to electrical signals, wherein the three-line CCD sensor includes three lines arrayed in parallel with the main-scanning direction, each of which has a line width that is determined by the magnification of the lens; and a carriage for moving the color filter set in the sub-scanning direction. The color filter is removable to allow the color separation apparatus to perform double duty in a copier and/or scanner in color or black/white mode.
