Abstract
An optical document reading apparatus which minimizes color moire phenomenon effects including an optical imaging system, and a line image sensor having sensor elements arranged in a line and color filter elements disposed on the sensor elements. A plurality of sensor elements are assigned to one pixel of said document, and the line image sensor senses light reflected from the document through the optical imaging system. The apparatus has a magnification condition which is determined from a distance between the document and the optical imaging system and a distance between the optical imaging system and the image sensor. The magnification is selected to be such that the optical imaging system does not precisely image the document onto the image sensor.
