Patent number: 5416605Abstract: A print control method for a microfilm reader enlarges a recorded image on a microfilm to the size of an original copy and projects the image on a screen; detects a black frame from an array indicated by image signals which are obtained by being binarized; selects one or more images from the entire area of the images; modifies images other than selected image to black frames; erases the modified black frames; enlarges the selected images at a magnification which can be arbitrarily set; and prints them out. The entire enlarged and projected image without any missing parts is included in the display area of the screen without making the screen too large. If plural images are contained in the display area of the read image, or if part of an image is outside of the display area, it is possible to output only the required images by extracting them and erasing unnecessary images together with the black frames. Moreover, paper can be efficiently utilized by arbitrarily changing the print magnification.Type: GrantFiled: March 30, 1994Date of Patent: May 16, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Takahiro Hideshima, Ushio Anayama

Patent number: 5406350Abstract: A microfilm camera which is adapted to photographing images on a reduced scale of documents placed on a support table and to photograph a mark also on the film in the vicinity of each image thereon so that the location and/or size of the original image corresponding to the document photographed can be located from the size and location of the marks by automatic retrieval equipment. When a bad or unsatisfactory exposure is made, the operator merely presses the appropriate button(s) and the unwanted image on the film does not receive either an image address or an image mark and for all intents and purposes, the image is "lost" on the roll of film. The unwanted image is on the roll of film, but it cannot be automatically retrieved because the image does not have an image mark associated with it. This error correction is accomplished by having the document photographed and the film moved a distance of at least one image frame before the image mark and image address are applied to the film.Type: GrantFiled: December 27, 1993Date of Patent: April 11, 1995Assignee: Eastman Kodak CompanyInventors: Stephen H.

Patent number: 5122645Abstract: Two bar code sensors are disposed at opposite sides of a passage of a photographic film, each bar code sensor having two photosensors disposed along a line perpendicular to the transportation direction of the photographic film. Each time a photographic film is fed by a predetermined distance, signals outputted from the two bar code sensor units are sampled and are compared with the signals obtained at the second preceding sampling timing to convert them into binary signals. Based on the data configuration of binary signals, i.e., based on the discrimination between the start code and end code, or the presence or absence of a clock track, automatic discrimination is performed between DX bar code data and frame number bar code data which then are decoded into a film type and frame number, respectively. The setting conditions of a photographic film also can be determined based on the bar code data configuration. An alarm is output if the setting conditions are not normal.Type: GrantFiled: February 27, 1989Date of Patent: June 16, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoshihiko Saeki, Yoichi Ujiie, Syuji Tahara, Kanji Tokuda

Patent number: 5119126Abstract: When printing a frame of a film immediately after developing the film, a mini-lab photofinisher observes the frame that is positioned in a printing station of a mini-lab type printer-processor, so as to input exposure correction data as needed. While positioning the frame in the printing station, frame number bar codes recorded on the film are read to determine the number of the frame. The determined frame number is printed on the reverse of the print image made from that frame. After printing all the frames, a bill printer prints the frame numbers of the printed frames and the corresponding exposure correction data, along with the photofinishing price. When making extra prints, the necessary number of extra prints is written in the bill slip, so that the photofinisher may finish the extra prints with substantially the same quality as the original print by referring to the exposure correction data printed in the bill slip.Type: GrantFiled: February 4, 1991Date of Patent: June 2, 1992Assignee: Fuji Photo Film Co., Ltd.Inventor: Kanji Tokuda

Patent number: 5101225Abstract: A magnetic layer is included as an additional layer in a photographic film. Information exchange between various uses of the film, such as the camera user, the dealer and photofinisher, is facilitated by recording data in dedicated frame-limited longitudinal track(s) in said film. All data is recorded on the film using a self-clocking three-part code in order to provide automatic data synchronization between the various users without requiring film transport at the same speed or even a uniform speed when reading and writing data. Three-part encoded binary characters uniquely representing start and stop sentinels respectively, are recorded at the beginning and end of the track respectively and facilitate automatic detection of the direction of film strip transport.Type: GrantFiled: April 18, 1991Date of Patent: March 31, 1992Assignee: Eastman Kodak CompanyInventors: Michael L. Wash, Arthur A. Whitfield

Patent number: 5099270Abstract: This invention is directed to the storing of digital information. This storage system comprises a number of layers of transparent or translucent material. In each layer there is a chemical or chemicals subject to change by being contacted with different electromagnetic wave lengths. For example, if there be eight layers then the chemical or chemicals in any layer is subject to be changed by an electromagnetic radiation of a wave length different than for any of the other seven layers. In this manner, with eight layers it is possible to have an eight bit byte. Actually, under premutations and combinations it is possible to have as many as eight bit bytes from the eight layers. It is conceivable that there may be more than eight layers such as sixteen layers of thirty-two layers. There is the possibility of storing large amounts of information in a small volume.Type: GrantFiled: February 1, 1989Date of Patent: March 24, 1992Assignee: Thomas W. SecrestInventors: Robert E. Pearson, Richard Schurman, John Schurman, Steve Reiter, Rick Clark
