ABSTRACT:
A method and an apparatus for reproducing a halftone image by scanning without any use of a contact screen, wherein a recording light beam of horizontally flat shape scans the surface of an aperture plate and is suitably deflected in both vertical and horizontal directions by image signals obtained from a memory according to the scanning of an original picture. The vertical deflection of the beam makes it possible for the beam width to change or the width of an intercepted portion of the beam to change, and the horizontal deflection of the beam makes it possible for the center of the beam to shift sideways in proportion to the tone density in the original as well as a required screen angle. The reproduced halftone image may have any of a range of screen angles. Further, the resolving power is greatly increased; in other words, continuous tone in the original may be more accurately reproduced since it is possible to set a width of scanning line which is narrower than the halftone dot interval.
