ABSTRACT:
An image processing apparatus or system with enhanced half tone expression in a reproduced image and capable of preventing deterioration in reproducibility of characters and letters to be reproduced, which is constructed with an image signal input unit, half a tone expressing unit for processing the input image signal from the image signal input unit and expressing a plurality of half tones on the basis of dither patterns, and a unit for further processing of the half tones with respect to each of the outputs from the half tone expressing means, and forming half tone outputs. Recording signals having different respective pulse widths corresponding respectively to respective plural dither process units may be output, such plural dither process units serving to provide continuity of dither processing at a junction of line sensors or the like.
