摘要： An image scanning and reading apparatus comprises a transparent drum (1) fro supporting a plurality of originals (2, 2′) and calibration reference portions (3, 3′) serving as references in reading the respective originals. A scanning head (5) is provided for scanning the rotating drum and an arithmetic unit (21) has a memory (20) for storing the positions of the calibration reference portions or the drum. The position of the calibration reference portions is stored prior to the reading of the originals and, when the scanning is started, the scanning head is moved to the stored position of a first calibration reference portion, the calibration is effected and the corresponding original is read taking the calibration data into account. The scanning of each successive original is similarly preceded by re-calibration using the corresponding reference portion, each calibration operation taking place while the drum is still rotating.

摘要： In an image recorder, a recording photobeam (25) and a reference photobeam (26) are periodically deflected by a polygon mirror (28) in the main scanning direction (X). The recording photobeam is supplied to a photosensitive film (600) while the reference beam is supplied to a transparent grating scale (31) on which a transparent area (T p ) and an opaque area (S d ) are formed. The combination boundary of the transparent area and the opaque area has a portion parallel to the main scanning direction. The reference beam transmitted through the transparent area is detected, and the photobeams are deflected in the subscanning direction (Y) by an acoustic-optical deflector (27) in response to the detected optical amount of the reference photobeam.

摘要： An amount of a read position error in the subscanning direction between line image sensors (CCD1, CCD2, CCD3) is obtained by scanning and reading a correction read pattern (6a, 6b). In scanning of an original, output image signals from the line image sensors (CCD1, CCD2, CCD3) are relatively delayed by a line number corresponding to the amount of the read position error between the line image sensors (CCD1, CCD2, CCD3), to correct time difference, caused by the read position error, in information reading in the boundary portion of the line image sensors.

摘要： A raster output scanner having a movable imaging member and high intensity imaging beam for exposing the imaging member to create images thereon. A rotating polygon scans the beam across the imaging member in line by line fashion while a modulator astride the beam path modulates the beam in accordance with image signals or pixels input thereto. A clock provides clock pulses for clocking the image pixels to the modulator. To assure uniform image size despite variations in the velocity of the imaging member, a control signal representative of imaging member velocity is used to control polygon velocity and maintain a predetermined velocity relationship between imaging member and polygon. Means are provided to servo clock frequency with polygon rotation, with a control to shift the clock servo midpoint frequency in response to changes in imaging member velocity.

摘要： A method of patterning a perforated screen printing screen (9) having a lacquer coating filling its perforations (10) using a laser engraving device includes the steps of locating the position of the locus of aligned perforations (10), aligning an engraving head (7) of the laser engraving device with the locus of the perforations (10) and then selectively actuating the laser to remove the lacquer individually from those perforations (10) which it is required to unblock. The laser engraving device includes a scanner (1,2) for scanning the laser engraving head (7) over the surface of the screen (9), a detector (8) for detecting the locus of the perforations (10) extending in the scanning direction of the laser engraving head (7) and the location of each perforation (10) in the scanning direction, alignment devices (4, 5, 6) responsive to the output of the detector (8) to align the laser engraving head (7) with the locus of the perforations (10) detected by the detector (8), and a laser actuation control (20, 21, 24) to enable the laser to be actuated only when it is aligned with the individual perforations (10).

摘要： A novel closed loop direct position feedback control method and recording apparatus for producing on a recording medium a plurality of successive print lines or otherwise component images. An appendant demarcation device provide for the proper abutting and spacing of each independent print character to prevent or minimize any perceived "banding" in the printed image. The apparatus includes a device for transporting the medium along a path orthogonal to the print head, a recording station in the path and having a translating head for inking, pring, or otherwise suitable device, for producing single lines or swaths of print in conjunction with the indexed advance of the medium relative to the print head. The transport device is operative to advance a first print line or swath through the recording station to form a first print line, to identify and store the position coordinates of each print line or swath, and to advance the recording medium for successive line or swath printing. The direct position feedback control apparatus also includes demarcation sensing and printing device for relative positioning, whereby the distance between the location of any sensed or printed demarcation reference and the next successive print line is controlled such that each print line will neglect the positioning error in any previous print line or swath.

摘要： The present invention provides a scanning system, producing and storing a digital representation of an image, comprising:

a support, for the image to be scanned, and a carriage which are movable relative to one another in a longitudinal direction;
a probe, movable on the carriage in a direction transverse to said longitudinal direction, for producing a digital signal related to the density of the image;
a digital computer for producing digital control signals for controlling the relative movement of the support and the carriage and the movement of the probe on the carriage so that the probe can be scanned over the image; and
pulse generating means for generating a synchronisation pulse when the probe has moved a predetermined distance in the transverse direction for enabling digital image signals produced by the probe at each position during its scanning to be transmitted to the digital computer,
the digital computer being arranged to receive the digital image signals produced by the probe and the pulse from the generating means, and to correlate the pulse, the digital image signals and the digital control signals to produce a digital representation of the image for storage in the computer.

摘要： Apparatus for reading out individual x-ray images recorded on a double-emulsion radiographic film or on separate films that were coincident when exposed simultaneously to a polyenergetic or broad x-ray photon energy spectrum beam emergent from a body and where an image corresponding to one obtained with a low energy part of the spectrum is formed on one film and an Image corresponding to a higher energy part of the spectrum is formed on the other. One readout apparatus ia for the case of two separate films which, after development, are illuminated from the back and optically scanned to derive analog signals representative of the intensities of spatially corresponding picture elements on each film. Another apparatus is for the case where the two images are on opposite sides of a film and are represented by alternate fine image information lines obtained by interposing a grid during the x-ray exposure. Another is for the case where a reflective layer is disposed between the film images during readout. In all cases the films are optically scanned and the resulting analog signals are digitized and variously processed to yield an image representative of that which is different between the two original different energy images.
