Title: Image contrast control system, halftone image forming method and electrophotographic printing device
Inventor: RATHBUN DARREL R
IPC: G03G15/043
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To obtain a system for controlling the contrast of a copy by controlling so that the total quantity of light radiated from 1st and 2nd light radiation sources may be kept constant in substance while changing the intensity of the light radiated from the 1st and the 2nd light radiation sources. SOLUTION: Image contrast is controlled by changing the intensity of the light radiated from two light sources to produce an image mode latent image, that is, an image forming lamp 30 and a line screen lamp 45. In the case of adjusting the contrast of a photographic mode copy by changing the intensity of the light from either the lamp 30 or the lamp 45, the darkness of the entire output copy keeps the total output of the light from the lamps 30 and 45 constant in substance. Therefore, the contrast is changed as the function of the ratio of the light radiated from the lamps 30 and 45. Thus, the system for controlling the image contrast is obtained.
