<p>An electrophotographic copying machine adapted to operate in either a functional or a pictorial mode, such that, in the pictorial mode, a light signal is transmitted through a line screen member (44) to modulate an electrostatic latent image of an original document. The amount of light transmitted through the line screen is varied as a function of the amount of light used to generate the electrostatic latent image to control the contrast of the image generated thereby. As a result, pictorial image contrast is readily adjustable by regulating the light intensity of the light transmitted through the line screen member (44) and onto the photoconductive surface for high quality pictorial copies in an electrostatographic copying machine. <IMAGE></p> |
