Patent number: 5850580Abstract: The improved method and apparatus for recording a stereoscopic image read a plurality of original images photoelectrically, split each original image into linear images of a desired pitch, perform any necessary image processing operations such as arranging the linear images in the recording order, and record the linear images by scan exposure on a lenticular light-sensitive material having a lenticular sheet and a recording layer. The method and apparatus permit the lenticular light-sensitive material to be scan exposed from the rear side and they also enable the linear images to be recorded with increased line width and a stereoscopic image to be formed with satisfactory registration between the principal objects of the original images. The improved lenticular light-sensitive material has an anti-halation layer provided between the lenticular sheet and the recording layer, thus permitting scan exposure to be effected from the rear side.Type: GrantFiled: June 5, 1997Date of Patent: December 15, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Seiichi Taguchi, Shunkichi Igarashi

Patent number: 5349419Abstract: The improved method and apparatus for recording a stereoscopic image calculate the linear image recording positions for each lenticular lens in connection with all of the linear images of the nth original image in such a way that all of the linear images of the nth original image that are to be recorded in association with the respective lenticular lenses will fall within the same area at the intended viewing position, and record the linear images by an image forming means on the basis of the results of said calculation. Therefore, according to the present invention, stereoscopic images of high quality can be recorded using the lenticular sheet without causing any serious defects such as multiple image or image flickering.Type: GrantFiled: April 14, 1993Date of Patent: September 20, 1994Assignee: Fuji Photo Film Co., Ltd.Inventors: Seiichi Taguchi, Shunkichi Igarashi

Patent number: 5302989Abstract: In the improved method for projection a stereoscopic image, an additional lenticular sheet that has an appropriate level difference and a different pitch of lenticular lenses than a lenticular recording material such as a lenticular light-sensitive material is either placed directly on top of said lenticular recording material or inserted above and in the vicinity of said lenticular recording material, with said additional lenticular sheet being preferably moved either in one direction or reciprocally in a direction generally perpendicular to its own generatrix. This method can be implemented with the improved apparatus for printing a stereoscopic photograph. Using the improved method and apparatus, the development of moire can be suppressed and, at the same time, the line width of linear image elements to be recorded can be easily expanded.Type: GrantFiled: October 1, 1992Date of Patent: April 12, 1994Assignee: Fuji Photo Film Co., Ltd.Inventors: Seiichi Taguchi, Samon Hosoya, Shunkichi Igarashi

Patent number: 5192969Abstract: In processing a plurality of original images from different viewpoints through a lenticular sheet having a plurality of lenticular lenses to form a plurality of corresponding linear picture elements that are to be projected on a picture element recording or display medium, the following steps are taken: launching the beams of light from the respective original images into one or a corresponding number of projection lenses; separating the transmitted beams for the respective original images by means of a mirror optical assembly consisting of mirror units each composed of at least two mirrors for each original image; adjusting the optical pathlengths of the beams to the picture element recording or display medium by means of the mirror assembly; adjusting the key subject matter in the mirror assembly so that it will register among the projected views of all original images; allowing the beams to be incident on lenticular lenses at predetermined projecting angles; and imaging those beams as linear picture elemenType: GrantFiled: March 27, 1992Date of Patent: March 9, 1993Assignee: Fuji Photo Film Co., Ltd.Inventors: Shunkichi Igarashi, Seiichi Taguchi

Patent number: 5099321Abstract: A microfilm searching and reading device for selecting a microfilm cartridge containing a target image from multiple microfilm cartridges and for reading the target image to produce image signals. The device is composed of a storage rack and a scanner including an image reader and a driving unit for winding and rewinding the microfilm roll contained in the selected microfilm cartridge. According to one aspect of the invention, the scanner is moved along the vertical direction to a position aligned with the selected cartridge and then the selected cartridge is ejected from the rack to be received by the scanner. According to another aspect of the invention, the scanner is moved into the rack to receive the selected cartridge to read the target image and then retracted from the rack. According to a further aspect of the invention, the scanner includes a driving unit which has a drive shaft removably engaging with the driven shaft of the selected cartridge.Type: GrantFiled: March 17, 1989Date of Patent: March 24, 1992Assignee: Fuji Photo Film Co., Ltd.Inventor: Shunkichi Igarashi

Patent number: 5060407Abstract: An aperture card which carries image information in a microfilm mounted on a rectangular paper sheet is widely used as it can conveniently record and control a large volume of image information separately. The aperture card carries a microfilm which records retrieval information corresponding to images of the microfilm at a position peripheral to the images. As such structure of this invention aperture card permits automatic recording of the retrieval information concurrently with the preparation and duplication of the cards, this invention can realize the preparation/duplication system for the aperture cards at a lower cost than before. As the printer suitable for the aperture card can read the retireval information recorded on the microfilm and record them in characters or punches, it can reduce the cost of the system due to the abbreviation of the manufacturing processes and increase the memorandum capacity on paper. The printer may be applicable to automatic punch systems.Type: GrantFiled: June 28, 1990Date of Patent: October 29, 1991Assignee: Fuji Photo Film Co., Ltd.Inventor: Shunkichi Igarashi

Patent number: 4949106Abstract: A microfilm searching and reading device for selectively taking out a cartridge containing a target image from one or more microfilm cartridge stacks. The device comprises a framework defining at least one storing space extending substantially vertically for storing a stack of cartridges in a manner such that the cartridges are stacked one above another, a scanner for receiving a selected microfilm cartridge and having an image reader and an actuator for winding and rewinding the microfilm, a carrier for taking out the selected cartridge and for guiding the same to the scanner, and a restoring mechanism for putting the selected cartridge, after the target image has been read by the microfilm reader, in the lowermost or uppermost position of the storing space. The device further comprises a memory for storing the location of the restored cartridge, and a controller for controlling the carrier, the scanner and the restoring mechanism.Type: GrantFiled: March 17, 1989Date of Patent: August 14, 1990Assignee: Fuji Photo Film Co., Ltd.Inventor: Shunkichi Igarashi

Patent number: 4076412Abstract: Process for producing microfilm copies and apparatus therefor employing silver halide emulsion film which is provided in roll form, wherein subsequent to exposure of the frames of the image-carrier portion the film is advanced a set length without being exposed this unexposed portion constituting the tab portion of the succeeding microfilm unit, and then the exposed image-carrier portion of the film, also preceded by a tab portion, is detached by cutter means from the remainder of the film and processed independently in the same apparatus, and moved to the exterior of the apparatus. An identification code may be written manually on the tab portion of each microfilm unit or may be produced automatically thereon by supplementary film exposure means upon exposure of the first frame of the image-carrier portion of each microfilm unit.Type: GrantFiled: June 7, 1976Date of Patent: February 28, 1978Assignee: Fuji Photo Film Co., Ltd.Inventors: Shunkichi Igarashi, Takeshi Okano, Sho Takahama, Yoshio Hakamata
