A compact color image reader for scanning an image in a short time is disclosed. The color image reader includes three fluorescent lamps 17 of red, green, and blue, a lighting circuit 15 for lighting the three fluorescent lamps sequentially, a CCD 183 for reading an image illuminated by the three fluorescent lamps and a control circuit 16 for controlling a lighting period of each of the fluorescent lamps 17 and the reading of the CCD. In order to perform the scanning of a color image in a short time, the lighting circuit 15 lights each of the three fluorescent lamps at a lamp current higher than a rated value and the CCD performs the fast reading in a period corresponding to the lighting period.
