Abstract:
A film card for use in an automatic microfilm display apparatus has a plurality of image frames, each bearing a marker image. One of the frames is a reference frame and includes only the marker image. The reference frame can be used for accurate positioning of a raster pattern on the remaining frames.
Abstract:
A film card retrieval device for use in an automatic microfilm display apparatus is provided with a switch for sensing that a film card has been retrieved. In the event the device fails to retrieve a film card, the absence of a switch output signal causes the control apparatus to repeat the card retrieval routine.
Abstract:
A digital microform imaging apparatus, comprising a chassis, a fold mirror supported by the chassis and including a reflecting surface for directing light from a first substantially vertical optical axis to a second substantially horizontal optical axis, a microform media support structure supported at a location intersected by the first optical axis, a first carriage supported for movement along a trajectory that is substantially parallel to the second optical axis, an area sensor supported for movement along the second optical axis, the area sensor further supported by the first carriage for rotation about an axis parallel to the second optical axis and a lens supported for movement along the second optical axis, the lens positioned between the area sensor and the fold mirror, a first motor mounted to the first carriage and linked to the area sensor for rotating the area sensor between at least two positions for obtaining portrait and landscape images of a microform media.
Abstract:
Apparatus for, and methods of, capturing and storing images in a self-contained digital microfilm scanning system without requiring a personal computer or software. A digital microfilm scanner captures an image from microfilm and sends the captured image directly from the digital scanner to a viewing device for displaying the captured image. The digital microfilm scanner also sends the captured image directly to a memory storage device, such as a memory card of the SD type with a USB connector. The captured images may then be transferred to a personal computer with a compatible port or printed by a printer with a compatible port.
Abstract:
A digital microform imaging apparatus which includes an approximately monochromatic illumination source transmitting an incident light through a diffuse window along a first optical axis of the apparatus. A microform media support is configured to support a microform media after the diffuse window and along the first optical axis. An approximately 45 degree fold mirror reflects the incident light transmitted through the microform media approximately 90 degrees along a second optical axis. An imaging subsystem includes a lens connected to a first carriage which is linearly adjustable approximately parallel with the second optical axis, and an area sensor connected to a second carriage which is linearly adjustable approximately parallel with the second optical axis.
Abstract:
A system and a method for the conversion of archived documents to a digital format and storage of the data extracted in repositories which may be easily extracted and searched by a user over a network such as the Internet. The data is preferably stored in the form of microfilm, although optionally the present invention could be operative with other types of physical media, such as microfiche, paper and any type of printed material. The microfilm data is preferably divided and/or grouped into at least one file. Optionally and preferably, each file undergoes the following automatic processing stages: combining files; analyzing image layout; segmentation; OCR; optional segmentation improvement; and output to XML, or another suitable output data format and/or language. In the last stage, the data contained in the files is preferably extracted and then more preferably transmitted to the relevant repository unit.
Abstract:
A microfiche device for producing microfiche has a light source emitting a light beam for exposing during an exposure time a microfilm based on a data stream supplied to the light source by a computer. During exposure, a relative rotational or linear movement between the light beam and the microfilm is carried out. In order to generate the data stream, documents to be stored on microfiche are digitalized. The microfilm is exposed with the light beam line by line length-wise or width-wise for generating images of different sizes and formats on the microfilm.
Abstract:
A microfilm reader and a control method therefor, suitable for reduction in size and enabling high-speed reading and efficient retrieval with less wear in the moving parts. The microfilm reader for reading an image recorded on a microfilm to supply an image data of the read image to a printer, comprising: a two-dimensional area sensor for reading plural images in respective frames of the microfilm to supply a first image data; a display for displaying the images continuously or intermittently by using the first image data so that an image of a target frame can be retrieved from the microfilm; a line sensor for reading the image of the target frame specified in the retrieval operation to supply the second image data of the target frame as the image data of the read image to be printed out. A line sensor capable of high-quality reading is used for the image to be printed out, whereas a two-dimensional area sensor with no mechanical moving part and capable of high-speed reading is used for the image to be displayed for reference.
Abstract:
The present invention is directed to a method and apparatus for scanning multiple images located on a first medium so that they can be automatically stored on a second medium with a high degree of accuracy and reliability, without the need for highly skilled operators to relocate and rescan images of the first medium which were improperly scanned or missed entirely. According to exemplary embodiments of the present invention, multiple images are scanned from a first medium as a block of image data so that cut, cropped or missed images, as detected by the user at the quality assurance station, need not be rescanned.
