Abstract: An automatic image calibration method is provided for a contact type scanner. The inventive method involves in first reading an image of a test chart that consists of at least a horizontal line and a plurality of slanting lines. Then, compute the calibration parameters according to the image of the test chart. The calibration parameters include a vertical displacement value, a horizontal displacement value, and a slope value. After obtaining the calibration parameters for each sensor chip, the initialization step is complete. The calibration parameters must be stored in a memory device for an application program to read. Later on, for each image read by the contact type scanner, the application program can automatically calibrate the image according to the calibration parameters stored in the memory device.

Abstract: A method and apparatus are provided for efficiently obtaining navigational position of a sensor array (22) based on a correlation between images captured by the sensor array at successive points in time. This is achieved by first acquiring a reference frame through said sensor array (22), successively acquiring a sample frame through said sensor array. Correlation data representing a relationship between the sample frame and the reference frame is then generated and a displacement of a reference feature contained in both the reference frame and the sample frame is determined based on the correlation data. The correlation surface of the correlation data is modelled as a general two-dimensional Taylor series expansion. The method and apparatus can be employed in a scanning device (10) to provide efficient scheme for obtaining navigational information based on a comparison of image frames captured by a sensor array of the scanning device at successive points in time.

Abstract: The invention relates to a method for engraving printing cylinders used for rotogravure in an electronic engraving machine. According to this said method, at least two engraving sections (A, B) of a given width (SB) are fitted next to each other, in the acial direct ion of the printing cylinder (1). These sections (AB) are engraved with their respective engraving element (3). Before engraving, an axial reference position is pre-set for each engraving element (3). The axial spacing between these reference positions corresponds to the pre-set widths (SB) of the engraving sections (A, B). The engraving elements (3) are placed approximately in their reference positions (RP). The differences in the axial spacing between the reference positions of the engraving elements (3) and the actual positions occupied as a result of the approximate positioning are then measured. During engraving, the engraving elements (3) are moved along the printing cylinder (1), still incorrectly spaced as a result of the approximate positioning. The spacing errors are compensated by displaced engraving of the engraving sections (A, b) on the printing cylinder (1), so that the engraving sections (A, B) have the pre-set widths (SB) despite the incorrect spacing between the graving elements (3).

Abstract: A printing machine includes a print head and a set of sensors adapted to accurately determine the relative position between the print head and a receiver (print media) onto which an image is to be formed. Any dislocation of the receiver from a predetermined nominal position is translated by a data conditioner into correction signals. These correction signals are integrated with nominal incoming image data directed to the print head. The print head then prints an image that compensates for positional variation of the receiver so that a resultant image is properly aligned with the receiver.

Abstract: A method for orienting a dual mouse optical scanner on an orthogonal grid pattern comprising the steps of (a) placing a dual mouse scanner on a grid pattern at a small angle to the vertical lines of the grid pattern and commencing motion detection with the two mice, (b) setting the coordinate position of each mouse at (0,0), (c) rotating the scanner in a predetermined manner while measuring the vertical distance on the grid pattern between the two mice for each new position of the scanner, (d) determining an average scanner position amongst all scanner positions having the same maximum vertical grid distance between the mice, and (e) establishing the coordinate position of one mouse at the average scanner position as the origin of a coordinate system in the memory of a computer in communication with the scanner and the vertical line closest to the origin and the coordinate position of the other mouse as the vertical axis of the coordinate system.
