    Abstract: Apparatus for and method of reconstructing a single document from data provided by scanning apparatus incapable of reading the entire document. A calibration sheet adapted to be disposed on the document to be scanned is used in the reconstructing apparatus. Scanning apparatus for converting a scanned portion of the document and a scanned portion of the calibration sheet into electronic outputs is used in the reconstructing apparatus. A computer processing unit is connected to the scanning apparatus to receive the electronic outputs. The computer processing unit includes storing apparatus for storing a first set of information representing a first scanned portion of the document and calibration sheet, a second set of information representing a second scanned portion of the document and calibration sheet and a third set of information representing a reconstructed single document. Also, the computer processing unit includes a converter for adjusting the first and second sets of stored information relating to the respective portions of the document scanned into alignment and spacing relative to a standard determined by the respective portions of the scanned calibration sheet and for merging the adjusted first and second sets of information to provide the third set of information.

    Abstract: A method of locating the position of an object on the platen of a raster input scanner having a movable scan carriage and an extended array of scanners is disclosed. The method includes the steps of obtaining a previously stored theoretical position of the object from a memory, locating the scan carriage at a position spaced a predetermined distance from the previously stored position, moving the scan carriage toward the previously stored position while operating at least some of the scanners until a target on the object is detected by the operating scanners, and storing a target position of the scan carriage where the target is detected. The target position can represent the location of the scanner's calibration strip or the registration position of a document. After the target position is stored, the scan carriage can be located at the target position for calibrating the scanners if the target position represents the location of the calibration strip. Alternatively, the scan carriage can be located at the target position prior to actuating the scanners for each subsequent document to be scanned if the target position represents a document registration position. This procedure is repeated to determine the document registration positions for documents which are placed on the platen manually, by an SADH or SALDH input, by a CFF input, or by an RDH input.

    Abstract: A scanner unit optically scans an original in a first direction to obtain an optical image. A mark is provided with a predetermined distance within a range in a second direction perpendicular to the first direction. The range is a range which can be scanned by the scanner unit. A line sensor is arranged in the second direction to read the optical image line by line in cooperation with the scanner unit. A converter converts a read output from the line sensor into digital data. An instruction section instructs to read the mark to the scanner unit and the line sensor prior to reading of the original. A distance calculating section calculates distance data corresponding to the predetermined distance of the mark in accordance with the digital data from the converter when the scanner unit and the line sensor cooperate to read the mark in accordance with an instruction from the instruction switch. A correction data calculating section calculates correction data corresponding to a difference between reference data and the distance data calculated by the distance calculating section. The correction data represents the number of bits of data extraction or addition corresponding to the difference. A read magnification correcting section executes bit extraction from or addition to the digital data from the converter in accordance with the number of bits represented by the correction data output from the correction data calculating section. A read magnification defined by the scanner unit and the line sensor is corrected to a defined read magnification corresponding to the reference data.

    Abstract: In the optical information recording apparatus, the form slide film having the sensor mark is two-dimensionally scanned so as to detect the drift amount in the vertical scanning direction due to the fluctuation of the optical system of the optical information recording apparatus. The scanning device scans the sensor mark within a predetermined scanning period to produce the pulse signals. The number of these pulse signals is counted and then compared with the reference number so as to produce a difference, i.e., the drift amount. The vertical scanning pitch of the scanning device is controlled based upon the drift amount.
