Patent number: 4270141Abstract: A method and machine for reproducing a picture are disclosed, in which a color original picture is scanned and the analog original picture signal thereby produced is broken into n separation picture signals, which are then digitalized. One of these separation picture signals is then stored in its entirety in a memory, while the others are sampled according to regular patterns, the sampled values being stored in the memory. Then digital output separation picture signals are read out of the memory, by reading out the first separation picture signal without alteration, and by reading out the others while interpolating between the stored values. The output signals are then used to record a reproduction picture. In embodiments, the entirely-stored picture signal can be a gray signal, while the sampled picture signals are color signals; or the entirely-stored picture signal can be a green signal, while the sampled picture signals are red and blue color signals.Type: GrantFiled: July 23, 1979Date of Patent: May 26, 1981Assignee: Dainippon Screen Seizo Kabushiki KaishaInventor: Takashi Sakamoto

Patent number: 4257072Abstract: 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.Type: GrantFiled: October 17, 1977Date of Patent: March 17, 1981Assignee: Dainippon Screen Seizo Kabushiki KaishaInventor: Takashi Sakamoto

Patent number: 4256398Abstract: A developing tank wherein means is provided to divide the surface of the developer charged into the tank into two separate portions, into one of which the film enters as it enters the developer, and out of the other of which the film leaves as it leaves the developer. Thus the contaminants and exhausted developer accumulating at the point where the film leaves the developer are prevented from directly moving along the surface of the developer to the point where the film enters the developer, and thereby streaking and uneven development are substantially reduced. The dividing means may be combined with a film entry guide plate.Type: GrantFiled: March 30, 1979Date of Patent: March 17, 1981Assignee: Dainippon Screen Seizo Kabushiki KaishaInventor: Masami Ohtani

Patent number: 4221960Abstract: A light ray emitted by a light source and which is to be modulated by an acoustic-optical modulator element is stabilized by its intensity being detected before it enters the acoustic-optical modulator element and being used to produce correction signals. The correction signals are used to amplitude-modulate a high-frequency carrier in reverse phase to the change of intensity of the light ray, to produce corrected carrier signals. Then the corrected carrier signals are further amplitude-modulated by control signals to produce modulator signals which are used to modulate the light ray in the acoustic-optical modulator element.Type: GrantFiled: November 13, 1978Date of Patent: September 9, 1980Assignee: Dainippon Screen Seizo Kabushiki KaishaInventors: Kiyoshi Maeda, Kyohei Fujisawa
