<p>PURPOSE:To provide a color image reader which can separate a clear color signal at a high speed without complicating a circuit system for a signal processing system. CONSTITUTION:The color image reader is provided with a bluish white fluorescent tube 7 whose spectroscopic intensity characteristic becomes low in the order of a short wavelength area having a peak value near 500nm, an intermediate wavelength area and a long wavelength area, a lens array condensing light reflected from the surface of an original, an image sensor 4 whose spectroscopic sensitivity characteristic becomes low in the order of the long wavelength area, the intermediate wavelength area and the short wavelength area, a color separation filter 41 separating the color of the light reflected from the surface of the original and an orthochromatic filter cutting the reflected light of a prescribed wavelength area. Then, when the white original is read, the outputs of the respective cells of the sensor 4 are balanced.</p> |
