Patent number: 5629752Abstract: In a method of determining an exposure amount, image data is fetched, and an image is divided into a plurality of regions by binarization or another technique, a shape pattern representing a contour of the head of a human figure is detected, and a face candidate region is set in accordance with the detected pattern. Next, a shape pattern representing a contour of the face of the human figure, a shape pattern representing an internal structure of the face of the human figure, and a shape pattern representing a contour of the body of the human figure are detected respectively. The consistency of a face candidate region is determined consecutively by the detected patterns, and a region having the highest probability of being a region corresponding to the face of the human figure is determined. The above processing is carried out a plurality of times while a threshold for binarization and parameters for controlling the relative fineness of the division of the image are varied.Type: GrantFiled: October 27, 1995Date of Patent: May 13, 1997Assignee: Fuji Photo Film Co., Ltd.Inventor: Naoto Kinjo

Patent number: 5619304Abstract: Rays of light from a super-high pressure mercury lamp are collected by an oval mirror, reflected by a cold mirror and additionally rendered parallel. The parallel light is passed through an interference filter and enters as incident light to individual lens units of a fly-eye lens. The individual lens units improve uniformity of intensity distribution and coherency of the light and act as isolated light sources. Right after the fly-eye lens is placed an aperture member that determines the form of an effective light source. The light passes through the aperture member, a cold mirror and a condenser lens to illuminate a reticle. A pattern of the reticle is projected on a semiconductor substrate coated with a photosensitive resin, by a projection lens system. The resolution property and exposure intensity of a reduction exposure apparatus is improved and aperture member positioning is facilitated. The throughput of the system can also be improved.Type: GrantFiled: November 29, 1994Date of Patent: April 8, 1997Assignee: NEC CorporationInventor: Tadao Yasuzato

Patent number: 5617181Abstract: An exposure apparatus and an exposure method for fabricating semiconductor devices or liquid crystal display boards. The scanning means synchronously moves the mask and the photosensitive substrate with respect to the plurality of projection optical systems, and patterns formed on the mask are projected onto the photosensitive substrate while images of mask formed by adjacent illumination optical systems are made overlapping with each other. On this occasion, the controlling means controls the light intensity changing means, and the light intensity changing means changes the intensity of a light beam of each illumination optical system, so that two intensities of overlapping parts in adjacent illumination areas become substantially equal to each other. The control by the controlling means is carried out based on the light intensities of the overlapping illumination areas as detected by the light intensity detecting means.Type: GrantFiled: March 15, 1996Date of Patent: April 1, 1997Assignee: Nikon CorporationInventors: Masamitsu Yanagihara, Hiroshi Shirasu, Tetsuo Kikuchi

Patent number: 5614989Abstract: A light source for a photographic printer which is designed so that almost all light energy emitted from a diffusing device can be utilized for printing, thereby markedly improving the light source efficiency. The light source is used in a photographic printer which illuminates a film (F) and projects an image of the film (F) onto photographic paper (P) to print the projected image on the paper (P). A diffuser (BD), which is disposed in an illuminating optical path in the vicinity of the film (F), is caused to perform reciprocative vibration in parallel to its own plane by a vibrating device (B), e.g., a voice coil, during the exposure time, so that, even if an image of dust or a blemish on the diffuser (BD) is formed on the print, the image becomes blurred on the photographic paper (P) because it moves during the exposure process, thereby preventing the print from being affected by the image of such an undesired object.Type: GrantFiled: March 13, 1995Date of Patent: March 25, 1997Assignee: Fuji Photo Film Co., Ltd.Inventor: Kanji Tokuda

Patent number: 5604565Abstract: A photographic printing device and film carrier. A negative film is inserted into the film carrier. When a leading end portion of the film is placed in a set state of being nipped by rollers, a conveyed amount count value is set to zero. While the film is conveyed, the count value is updated, and a position of an image recorded on the film is detected by detecting an edge of the image. A detected image is positioned at an exposure position, and print-exposure processing is carried out. A determination is made as to whether a film end flag is on by detecting a trailing end of the film. When the flag is not on, processing waits until a PASS key or a print designation key is turned on. When the trailing end of the film has not yet been detected and the PASS key is turned on, an image is positioned, and print-exposure continues.Type: GrantFiled: June 7, 1995Date of Patent: February 18, 1997Assignee: Fuji Photo Film Co., Ltd.Inventor: Teruo Takanashi
