Abstract:
A feeding device comprises a pair of guide shafts, and a film holder which is movably supported by the guide shafts. A slide-mount, which holds a film, is attached to the film holder. Guide members are formed on side surfaces of the film holder, and are slidably engaged with the guide shafts. Each of the guide members has a first bearing member and a second bearing member. The first bearing member and the second bearing member are offset in a direction in which the guide members extend. The first bearing member is engaged with an upper surface of the guide shafts, and the second bearing member is engaged with a lower surface of the guide shafts.
Abstract:
An image input apparatus with a main unit; a film holding adaptor, freely attachable or detachable to or from the main unit, for holding a film; a carriage for holding an illuminator for illuminating a film held in the film holding adaptor and an imaging unit for imaging the film illuminated by the illuminator; and an adaptor mount formed on the carriage and engaged with the film holding adaptor.
Abstract:
A scanner system digitizes 35 mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 51/4" floppy disk drive standard.
Abstract:
A transporting system for an image digitizer can handle both positive and negative transparent film material. The transport features accurate linear motion with high resolution in a single compact unit. For the processing of individually framed slides, an automatic eject mechanism is provided. Both manual and motor driven focus adjustments are provided. Individual images can be oriented by an angular adjustment option. A special carrier allows the system to process negatives in uncut strips. The transport can manage larger number of images using either a slide tray or roll feed attachment.
Abstract:
An apparatus providing the capability to scan media at different resolutions is presented. The apparatus comprises an image area which is disposed between scanner lid and a scanner base, the lid is pivotally attached to the base to provide easy access to the image area. A light source resides within the scanner lid. Two separate light paths are provided, the first light path is reflected off opaque targets, through the lid before entering the base and onto an array of photosensitive devices. The second light path is passed through transparent media, into the base and onto the array. First and second focusing lenses are provided, each for a light path. The focusing lenses provide two separate magnifications which yield two separate resolutions.
Abstract:
An optical system for scanning a transparency. The optical system includes a light source that emits a longitudinally and laterally diverging beam of light. A torodial shaped mirror is positioned to refocus the light beam along both its longitudinal and lateral axes so that it becomes a focused light beam. The inwardly converging light beam is directed onto the transparency to be scanned. A complementary light sensor is positioned to receive the illuminated beam of light formed as a consequence of the transparency scanning.
Abstract:
An image input system includes an image input device for reading image information from a source document and a feeder for automatically inserting the source documents into the image input device. The feeder includes a loading magazine storing source documents and an adjacent discharge magazine storing source documents discharged from the image input device. The source documents travel along a transport surface within the feeder. A dividing board controls the position of the source documents within the feeder. Detectors are provided to monitor the loading operation. A method of reading image information using the image input system is also disclosed.
Abstract:
An image reading apparatus comprises a light source for illuminating an image of a document sheet, an image pickup element for photo-electrically converting a light from said document sheet image, a display unit for displaying said document sheet image, an input unit for inputting an instruction to extract a desired area of said document sheet image, and an adjusting unit for adjusting a focus of an optical member for directing a light image from said document sheet image to said image pickup element. The adjusting unit adjusts the focus of said optical member when said input unit inputs the extraction instruction, and said display unit thereafter displays said document sheet image.
