  • Publication number: 20140218505
    Abstract: The invention is directed to a digital microform reader that has a form carrier. A light projection system projects light onto the form carrier. A digital imaging system images a portion of the form carrier. A computer communication data interface system receives an electronic image from the digital imaging system, wherein the digital microform reader does not contain a viewer. A light diffusion sheet may be used with a condenser lens of the light projection system. The digital imaging system includes a CMOS (Complementary Metal Oxide Semiconductor) detector. CMOS detectors are able to capture an image much faster than CCD (Charge Coupled Device) detectors. Because the system does not have a separate viewer it is much less expensive than prior art systems. The system also uses less energy than prior art machines because of its use of light diffusion sheets with the condenser lens and as a background for the microform.

  • Patent number: 7750935
    Abstract: A data recording and/or reproducing apparatus and method in which, during a recording operation, the maximum bit rate of a transport stream may be detected and along with the transport stream written into a storage medium. During a reproducing operation, the recorded transport stream and maximum bit rate information may be read from the storage medium and a band width or rate for transferring data over a digital interface may be set in accordance with the read maximum bit rate information. As a result, the digital interface band may be utilized for transferring data with a relatively high efficiency.

  • Publication number: 20080284847
    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.

  • Patent number: 6442296
    Abstract: A system and method for storing documents in human and machine readable format. A laser scanner is used to write de-magnified visual copies and digital records of the documents in an optical recording medium. A table of contents and record headers are provided to ease document retrieval. The optical recording medium is made of materials which can be written directly by the laser scanner without the need for post-writing processing. The direct write characteristic allows immediate retrieval, and allows additional documents to be added to the optical recording medium at later times. The documents are retrieved from the optical recording medium by either magnifying the visual copies or by regenerating the documents in visual form using the digital information.

  • Patent number: 6104841
    Abstract: An image is read by moving a line sensor relative to the image in a subsidiary scanning direction perpendicular to the direction of a pixels array of the line sensor. An image processor receives image signals from the sensor and produces an output image magnified relative to the image in accordance with a magnification ratio. The magnification ratio falls into one of n contiguous magnification ratio ranges between a reference magnification ratio and a minimum magnification ratio.

  • Patent number: 5808667
    Abstract: An index image which shows plural frames on a film strip within a film cartridge and/or a film image in one frame are displayed on a display. Information relating to automatic regeneration or automatic printing for regenerating plural film images on the film sequentially and automatically is entered by an user who is looking at the display. The entered automatic regeneration information or automatic printing information are recorded in a record medium which corresponds to the film cartridge. When the automatic regeneration or automatic printing is performed, the film player reads out the automatic regeneration information or the automatic printing information from the record medium, and automatically regenerates or prints the plural film images on the film strip in accordance with the readout automatic regeneration information or automatic printing information.

  • Patent number: 5703971
    Abstract: A process and device for analyzing image data and performing automatic optimization of a black and white image created by a scanner. The process and device performs dynamic thresholding by approximating the information level and the background level at every pixel in the image, the threshold being calculated as a function of the background and information levels at that point, and a characterization process step comparing the pixel intensity at that point with the threshold, so that if the pixel is darker, it is considered to be black, or if it is lighter, it is considered to be white.

  • Patent number: 5574577
    Abstract: An apparatus for digitally archiving analog film images includes a support surface on which an analog film image may be supported, and a digitizer that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light transilluminates the film image and projects it toward the digitizer through an objective lens which focuses the image. The positions of the digitizer and the lens along the Z axis are adjustable so that the size of the image projected onto the digitizing means can be varied. For example, it is possible to move the digitizer and objective lens between a range of enlarging positions in which the lens is closer to the film image than to the digitizer, and a range of reducing positions in which the lens is further from the film image than from the digitizer so that the film image may be either enlarged, reduced or reproduced at the same size before being sensed and converted into digital data.
