Abstract: Apparatus and method of processing microfiche images. The apparatus includes an unattended low-resolution wide area pre scanning station and an unattended high-resolution line scanning station. The low-resolution station automatically identifies active image areas and borders on a plurality of light passing documents transported in seriatim along a prescan path. The unattended low resolution scanning station generates a plurality of active image area signals indicative of the active image areas and borders in a plurality of light passing documents. The unattended high-resolution line scanning station includes a high-resolution line scanner that responds to the individual ones of said plurality of active image area signals. The high resolution scanning station automatically focuses the high resolution line scanner on only the active image areas of said light passing documents and then converts each scanned document image into a corresponding enhanced digital information signal that is indicative of the image information carried on the scanned document.

Abstract: A method and apparatus for providing localized control of film, allowing high speed and high resolution continuous digital scanning of the film. The method includes continuously and precisely transporting the film, capturing successive slit images, and storing the images. The apparatus includes the use of a drive system to control the transport of the media being scanned. In a preferred embodiment, a dual capstan drive system under the control of a single motor provides localized tension and location control for the continuous transport of the film to be scanned, the capstans comprising a metal shaft. The preferred embodiment further comprises pinch rollers immediately adjacent to the capstans, the pinch rollers comprising a metal shaft covered with an elastomeric material. As a result of the accurate localized control of the film, high speed scanning is possible.

Abstract: An image reading apparatus is capable of being switched between an observation state in which an image on a recording medium is projected onto a screen and observed and a read state in which the image is projected onto a reading unit and read. The apparatus includes a projecting lens provided in a lower portion of the apparatus to project the image, a rockable first reflecting member provided in an upper portion of the apparatus to reflect the image light from the projecting lens and, a second reflecting member provided in opposition to the screen to guide the image light reflected by the first reflecting member to the screen. A third reflecting member is provided below the second reflecting member to guide the image light reflected by the first reflecting member to the reading unit. The observation state and the read state are switched by the rocking motion of the first reflecting member.

Abstract: In an image reader a frame image of a microfilm is projected on a line sensor with a projection lens and read. The projection lens is movable in the main scanning direction by a driving motor. The line sensor is movable in the subscanning direction by a driving motor. The line sensor is moved in the subscanning direction to apply preliminary scanning and detect positional deviation in the main scanning direction of the projected image, and the projection lens is moved in the main scanning direction corresponding to quantity of the positional deviation. When the frame image is inclined, it is rotated relatively to the main scanning direction by a prism to correct the inclination, and the projection lens is moved in the main scanning direction thereafter to correct positional deviation in the same direction.

Abstract: A microfilm display device is responsive to a film address signal and controlled by a microprocessor to locate a desired film and select a film image for display on a cathode-ray terminal. The film image is converted to a video signal for display on the terminal. The video signal is used for fine positioning of the raster on a flying spot scanner which illuminates the film.

Abstract: The invention relates to a method for reading analogue and/or digital data, which are stored in fields on a microform, using a device for accessing the microform, which device is connected to a data processing system via a hardware interface. In addition, the invention relates to a device for carrying out the method and to a microform. In order to make it possible to further process the data acquired by the device in a conventional personal computer, the invention proposes that the analogue and/or digital data stored on the microform are represented by a control unit of the device of the data processing system as if the microform were a conventional replaceable data storage medium. Finally, the invention specifies an advantageous microform, the data of which can be read quickly and which, on account of its structure, is also suitable for the long-term and secure archiving of digital data, in particular.

Abstract: The invention relates to a method for automatically inserting documents for displaying on a display device and/or for copying in a digitisation device, such as microfiches, microfilm jackets or similar, which are conveyed one at a time from a holding magazine for a stack of documents to be processed to a document support and from there, to a deposit magazine for the processed documents. According to said method, the top document of a stack of documents in the holding magazine is drawn upwards by suction, approximately to the level of the document support, the remaining stack then being retained in the magazine by suction in the opposite direction. The document that is drawn up by suction is transported to the document support sideways and deposited on said document support by terminating the suction effect. After processing, the document is once again drawn by suction and transported to the deposit magazine.

Abstract: @ A microform reader for reading microfilm filmed at a reduction of about 200 times forms an image of a selected page on the microform on a linear solid state sensor which scans down the image of the page to produce a line-by-line or video-type representation of the page for transmission to a remote location. Selected lines of the sensor output are analysed to provide a determination of image parameters and enable the image-forming system to be adjusted to improve the transmitted image quality.
Thus each filmed page carries at its head a registration target of well defined shape such that a selected scanned line yields precise information as to the X-Y location of the page. Also selected pages include a focussing target including a pattern carrying a black/white discontinuities. Analysis of the scanned line representing the discontinuities gives a measure of the accuracy of focus enabling appropriate adjustment to be made automatically.
