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 form 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:
In the optical information recording apparatus, the form slide film having the sensor mark is two-dimensionally scanned so as to detect the drift amount in the vertical scanning direction due to the fluctuation of the optical system of the optical information recording apparatus. The scanning device scans the sensor mark within a predetermined scanning period to produce the pulse signals. The number of these pulse signals is counted and then compared with the reference number so as to produce a difference, i.e., the drift amount. The vertical scanning pitch of the scanning device is controlled based upon the drift amount.

Abstract:
Transparency imaging systems and methods. One embodiment of the transparency imaging system comprises an imaging surface and a cover mounted adjacent the imaging surface. A media adapter is provided as part of the cover, and a chamber is formed in the media adapter. At least one template is receivable within the chamber formed in the media adapter, the at least one template loading the transparency media in the media adapter adjacent the imaging surface for an imaging operation.
Abstract:
A film feeding apparatus for a film scanner includes a bottom plate, a top plate formed with a slide slot and a feed-in hole, a movable plate movable between the bottom plate and the top plate, and an actuator member co-movable with the movable plate. The movable plate cooperates with the actuator member to constitute a sliding seat that is movable between a non-feeding position whereat the actuator member is disposed in an end of the slide slot such that the movable plate is misaligned from the feed-in hole in the top plate, and a feeding position whereat the actuator member is disposed in an opposite end of the slide slot such that the movable plate is aligned with the feed-in hole. When the sliding seat is moved from the non-feeding position to the feeding position, a film is pushed into the film scanner.
Abstract:
A film scanner is disclosed. The film scanner can provide a preview, scanning and storage functions without connecting to a computer. It is characterized in that a PCBA module includes a main board, a function key board and a screen display panel, an image sensor with a lens and an image processing and storage module. A backlight mechanism is set near the bottom of the film scanner. In addition, a memory card inserting may be provided. The film scanner operates independently and allows a user to preview a digitalized image captured from a film.
Abstract:
A passive transparent media adapter magnetically coupling to a scan system is disclosed. The transparent media adapter captures light from a concentrated light source in the scan module and transfers the light to backlight transparent media so that it can be imaged by the scanner module. The transparent media adapter has no active electronics or illumination so does not require control or power to operate. The magnetic coupling allows a significant amount of the concentrated light to be focused into a narrow backlight region that moves in sync with the scan module.
Abstract:
A film holding apparatus for use with a scanner is provided. The film holding apparatus selectively holds a positive film and a negative film that are to be scanned. The positive film is thicker than the negative film. The film holding apparatus includes a base, a plate disposed above the base, and a pressing unit disposed above the plate. The plate has a surface for selectively receiving a positive film and a negative film. When the surface of the plate receives the positive film, the plate vertically moves for a distance toward the base. When the surface of the plate receives a negative film, the negative film is held between the surface of the plate and the pressing unit.
