Abstract: A modular scanning system (10) consisting of a first scanning unit (11) and a plurality of tethered scanning (13) and digital capture elements (150, 160) providing both sheet-fed, platen, and digitally captured documents and photographs. The first scanning unit (11) includes all the mechanisms necessary to permit sheet-fed scanning of documents. The platen scanner (13) provides a second scanning unit which performs platen scanning of documents on a glass top (26) of the platen scanner (13). Since the platen scanner (13) is detachable, the user has the option to select the platen scanning functionality but with the additional flexibility of selectively mounting or storing the platen element.

Abstract: A color image reading device, an output controller and a method of controlling an output from a color image reading device provide for an improved signal-noise ratio for the scanning of two-dimensional objects, as in document scanners. In the present invention, the position of a color image reading device with respect to an object to be read is oriented in order to optimize illumination in, for example, the blue wavelength. Pixel data for each line is read, generated in reverse order and/or re-phased so as to compensate for offset linear sensors on the color image reading device.

Abstract: According to one aspect of the present invention a scanner comprises a transport mechanism for moving a document. A sensor detects a leading edge and a trailing edge of the document. The sensor turns off a drive mechanism when a leading edge of the document is detected. A drive mechanism is started when a trailing edge of a document is detected. A camera scans the document and detects a skew angle of a leading edge and a trailing edge of the document. A front end controller receives a digital signal from the camera and detects the document in a field of the camera within a specified range of pixels.

Abstract: The invention relates to the making of reproductions of microfilm images which are scanned line-by-line using photoelectronic devices. The subsequent generation of images are reproduced onto photosensitive material line-by-line. By processing the video signal generated by scanning the first or original image, a series of parameters are produced which are stored either on the film or in a separate location. The second generation image is electronically scanned and the video signal processed to provide a second series of parameters. The first and second series of parameters are compared to provide an adjustment signal. The adjustment signal is then used to change or alter the second video signal prior to it being used to electronically reproduce the second generation image on film. The stored series of video parameters are used to produce subsequent generations of film images in a like manner.
