Patent number: 6597869Abstract: When a stop aperture formed by a shutter blade has reached a diameter corresponding to a predetermined f-number, a flash light is emitted and an exposure is performed with the flash light. Successively, the diameter of the stop aperture is gradually increased. When the stop aperture has reached a diameter corresponding to a set f-number, a color-temperature conversion filter is placed at a photographic optical path. Another exposure is performed with an illumination light which has passed through the color-temperature conversion filter.Type: GrantFiled: July 8, 2002Date of Patent: July 22, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Mitsuhiro Uchida, Yuji Kume

Patent number: 6301442Abstract: A lens-fitted photo film unit for photographing an object includes a flash charger button as mode selector, which designates a selected one of a flashless mode and a flashing mode. An exposure aperture forms a color image by object light from the object. The image, if the flashless mode is designated, is recorded with first color balance in the exposure aperture, and if the flashing mode is designated, is recorded with second color balance. An electronic flash unit applies flash light to the object. A light balancing filter as color balance adjustor subjects the object light to correction if the flashless mode is designated, so as to set the first and second color balance substantially equal to one another.Type: GrantFiled: February 29, 2000Date of Patent: October 9, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Mitsuhiro Uchida, Yuji Kume, Yasushi Nozawa

Patent number: 5059517Abstract: Disclosed is a silver halide photographic emulsion containing tabular silver bromide series grains having a mean aspect ratio of 2 or more, which is characterized by the grains having no projection on the grain surface and by the silver chloride content in the surface part of the grains being higher than that in the part of the grain which is underneath the grain surface. Also disclosed is a multi-layer photographic light-sensitive material having at least two silver halide emulsion layers on a support in which at least one of the silver halide emulsion layers contains the tabular silver bromide series grains as defined above. By the incorporation of the emulsion, the sensitivity, the storage stability and the manufacture stability properties of the photographic material are improved without deteriorating its graininess property.Type: GrantFiled: June 25, 1990Date of Patent: October 22, 1991Assignee: Fuji Photo Film Co., Ltd.Inventors: Mikio Ihama, Yuji Kume, Koji Tamoto, Hiroshi Ayato
