Abstract

PURPOSE:To emphasize the surroundings of an image and improve the image quality with the formation of color gradation on its surroundings by synthesizing a train of pulses of the reflecting light of a document via differential calculation circuit and averaging circuit in order to form a light beam for making an image by modulating the light from the light source with the pulse signal.
