Abstract
A color image reader according to the present invention has a reading object holder which is plate shape and which can transmit light and holds the subject to be read, a lighting device for illuminating the subject to be read on the reading object holder a reducing lens for providing convergence to the image light from the reading object, a 3-line CCD sensor for receiving the image light with convergence given by the reducing lens and outputting three electrical signals corresponding to the image light, and a lateral chromatic aberration correction circuit for designating one output signal of the three output signals outputted from the 3-line CCD sensor to the reference, comparing the two remaining output signals with the output signal used for the reference, and providing a predetermined correction to the two remaining output signals, and can suppress generation of image color deviation which depends on the distance between the 3-line CCD sensor and the optical axis of the reducing lens.
