Publication number: 20070215788Abstract: An exposure apparatus of the invention has a dot array head of a fluorescent type having light-emitting units UR, UG, UB of three primary colors. A controller E is provided with an area dividing unit that divides the dot array head into an image area, in which control of light emission based on image data is performed, and the other non-image areas. In addition, a dot array head control unit in the controller E comprises a light emission control unit that controls the dot array head such that light is emitted based on the image data in the image area and dummy light emission takes place in the non-image area when exposing photographic paper. The dummy light emission data is created by the dummy light emission data creating unit, based on image data corresponding to a single dot D1 adjacent to a boundary of the image area and the non-image area.Type: ApplicationFiled: March 16, 2007Publication date: September 20, 2007Inventors: Takeshi Nishihara, Akihiko Toki, Hisashi Oda

Patent number: 6760055Abstract: A photographic processing apparatus according to the present invention exposes photographic papers using a laser beam modulated based on image data and includes a laser beam emitting device. A changeover part changes the level of a driving signal to any one of a plurality of discrete levels according to a coloring characteristic of the photographic paper. The level of the driving signal determines the intensity of the laser beam outputted from the laser beam emitting device in a plurality of levels (for example, three levels consisting of a high level, a middle level and a low level). A filter is also provided to reduce the intensity of the laser beam outputted from the laser beam emitting device.Type: GrantFiled: June 21, 2002Date of Patent: July 6, 2004Assignee: Noritsu Koki Co., Ltd.Inventors: Akihiko Toki, Yoshiharu Tokumatsu
