A digital microform imaging apparatus includes a bracket movably coupled to a chassis. A microform media support is coupled to the bracket and includes a frame and a window supported by the frame. An illumination source is provided to direct light through the window of the microform media support along an optical axis. An optical sensor is positioned along the optical axis. A motor is operatively engaged with the microform media support to move the bracket and frame relative to the chassis along an axis perpendicular to the optical axis.

Automatic microform carrier systems and methods

Systems and methods use a digital microform imaging apparatus for sensing an image mark on the microform containing the image of a document. The use of an area sensor with an adjustable region of interest can be used to improve the detection speed of image marks as a roll of microform is being transported.

Image mark sensing systems and methods

Systems and methods use a digital microform imaging apparatus for sensing an image mark on the microform containing the image of a document.

A digital imaging system and method for searching for expressions that appear on a microform medium, the system having a computer including a processor and an input device, and a digital microform imaging apparatus having an area sensor generating a digital microform image of the microform medium. The computer is configured to receive a search expression from the input device, create an expression template representing a shape of the search expression, and search the digital microform image for instances of the expression template.

Microform word search method and apparatus

A digital imaging system for real-time searching for expressions that appear on a microform medium, the system comprising a computer including a processor, a display, a temporary memory, and a non-volatile memory, and a digital microform imaging apparatus including a controller and an area sensor generating a real-time digital microform image of the microform medium. The controller is in communication with the area sensor and receives the image. The controller is in communication with the processor and outputs the image to the processor that temporarily stores the image in the temporary memory. The processor uses the image output by the controller to drive the display with the image being generated by the area sensor in real-time. The processor searches the image used to drive the display for instances of a search expression, the processor visually distinguishing identified instances of the search expression on the display.

An apparatus for searching for expressions that appear on a microform medium, the apparatus comprising a microform imager including a sensor for generating digital microform images of one segment of the microform medium at a time, a display screen; and a processor programmed to, while the microform imager is generating a digital microform image: (i) use the digital microform image generated by the microform imager to drive the display screen, (ii) search the digital microform image presented via the display screen for instances of a search expression and (iii) visually distinguish the located search expressions in the digital microform image presented via the display screen.
