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.

Systems and methods to generate a multi-mode image containing different modes such as color, grayscale, and black and white to minimize digital file size while retaining the desired modes for selected portions of the image.
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.
G06K 9/18 - Methods or arrangements for reading or recognising printed or written characters or for recognising patterns, e.g. fingerprints using printed characters having additional code marks or containing code marks, e.g. the character being composed of individual strokes of different shape, each representing a different code value
G06K 9/00 - Methods or arrangements for reading or recognising printed or written characters or for recognising patterns, e.g. fingerprints
A microform imaging apparatus comprising a chassis including a microform media support structure configured to support a microform media within a plane substantially orthogonal to a first optical axis, a fold mirror supported along the first optical axis to reflect light along a second optical axis that is angled with respect to the first optical axis, a lens supported along one of the first and second optical axis, an area sensor supported along the second optical axis, a first adjuster for moving the area sensor along at least a portion of the second optical axis and a second adjuster for moving the lens along at least a portion of the one of the first and second optical axis.
