ABSTRACT:
A color image reader has a three-primary-color light source for emitting blue-light rays, red-light rays and green-light rays. The light-source is controlled such that the emissions of the blue, red and green light rays are cyclically performed in the order of the blue-light rays, the red-light rays, the green-light rays and the red-light rays. An object to be read is continuously moved, such that the object is illuminated with the cyclical emissions of the blue-light rays, red-light rays and green-light rays. A one-dimensional line image sensor optically and electronically senses a monochromatic image of the object illuminated with each of the cyclical emissions of the blue-light rays, red-light rays and green-light rays.
