  • Patent number: 5995202
    Abstract: A method and apparatus for producing index prints makes the trend of compensation for main prints coincide with the trend of compensation for the index prints. When a scanner determines an exposure compensation amount for each frame based on image data of each frame of a negative film, the information representing the exposure compensation amount for each frame is transmitted to the drive controllers via a controller. In a main print section, an exposure process is performed by the drive controller based on the information regrading the exposure compensation amount for each frame, thereby obtaining a main print. In an index print section, an exposure process is performed by the drive controller based on the same information regrading the exposure compensation amount for each frame, thereby obtaining an index print. Also, a density adjusting method easily and automatically adjust unevenness in density produced in an image printing stage.

  • Patent number: 5973765
    Abstract: A method and an apparatus for printing images on different mediums, such as images recorded on a photographic film and index print images onto photographic paper while an image printing device is reduced in size. A film carrier is positioned to a first position so that images recorded on a negative film set on the film carrier are exposed by a light source. Further, the film carrier is moved to a second position so that images formed on a liquid crystal panel are exposed by the same light source as that used for the exposure of the images on the negative film.

  • Patent number: 5926253
    Abstract: An apparatus for exposing index prints, in which a plurality of images recorded on a photographic film are displayed on an image display device and a photographic printing paper is exposed by light transmitted through the image display device so that an index print is prepared on the photographic printing paper such that the plurality of images are arranged in a matrix. The apparatus includes a system for setting the number of frames displayed on the image display device and exposure magnification of the images displayed on the image display device; dividing a plurality of image frames of the photographic film every predetermined number of frames to be displayed on the image display device; displaying, on the image display device, the plurality of image frames of the photographic film every predetermined number of the divided image frames; and exposing the divided plurality of image frames on the photographic printing paper at predetermined intervals in accordance with display of the image display device.

  • Patent number: 4994850
    Abstract: An image frame selecting apparatus for a photographic printer which is adapted to designate an image frame to be printed among image frames of a short photographic film. The apparatus includes operating devices the number of which is identical with that of the image frames of the short photographic film photographed and which are arranged in correspondence with the image frames of the short photographic film, the operating devices being adapted to select an image frame to be printed; an image frame designating device for designating the image frame corresponding to an operating portion of an associated one of the operating devices; a conveying device for conveying the short photographic film; and a controlling device for controlling the conveying device in such a manner that the image frame designated by the image frame designating device is positioned to a printing position.
