Abstract
An image processing apparatus utilizes plural image signals, generated with mutually different characteristics, such as screen angle, to modulate plural light beams in order to obtain different colors. Each of the plural image signals is pulse-with modulated respectively with different analog pattern signals to generate the respective plural pulse-with modulated signals in order to modulate the light beam. The analog pattern signals are generated in synchromism with a synchronizing signal associated with the recording beam so as to have, for example, mutually different phases to obtain the mutually different screen angles in the reproduced image formed by the modulated beam. Accordingly, unpleasant moire effects in the reproduced image may be avoided.
