摘要： An image reading unit reads an original image, one main scan line by one main scan line, in a sub-scan direction. A window setting unit sets a measuring window in a bit-map formation of image data obtained through the image reading unit, in a manner in which the measuring window moves in a predetermined manner so that the measuring window appropriately includes pixels of an oblique line image which is formed in the bit-map formation of image data as a result of being read through the image reading unit. A position error measuring unit processes image data defined by the measuring window, and, thus, measures an error of the oblique line image formed in the bit-map formation of obtained image data between a predetermined reference state and an actual reading state.

摘要： An image reading apparatus includes a reference pattern having slanting lines, which is provided outside a reading range and read by image sensors arranged at separate positions in a sub-scanning direction. A reference-position determining unit detects one of the slanting lines in the reference pattern based on image data output from one of the image sensors so that a position of the image data when one of the slanting lines is detected is determined as a reference position. First and second delay units have line memories which store image data read out from an original image having lines, the delay units delaying outputting of the image data from the line memories line by line. First and second determining units determine image data having color values at imaginary points. An error measurement unit selects one of the imaginary points whose image data has a minimum difference between the color values of the image data. First and second line correcting units output image data having the color values at a corrected position of each picture element by using an interpolation function, the interpolation function having a set of correction factors determined based on a distance between the selected imaginary point and the reference position.

摘要： First and second patterns are located outside of an image reading area. A first pattern comprises a plurality of lines each extending at a fixed angle with respect to a sub-scan direction. A second pattern comprises a plurality of lines each extending at a fixed angle but having a reverse direction with respect to the sub-scan direction. An image reading portion reads the first and second patterns. A position error measuring portion measures first and second image reading position errors corresponding to different angle oblique lines of the first and second patterns of image data obtained as a result of reading the first and second patterns, respectively. The position error measuring portion compensates for position deviations of the first and second patterns using the first and second image reading position errors, and obtains position-deviation-compensated image reading position errors. A position error correcting portion corrects image data read by the reading means using the position-deviation-compensated image reading position errors.

摘要： An oblique line pattern is located outside of an effective image area and comprises a plurality of lines with a fixed inclination to the main scan direction. A reading unit, extending in the main scan direction, reads the oblique line pattern together with an original image which is placed in the effective image area. A setting portion is provided for an operator to set an image size change rate for the original image. A sub-scanning portion changes an original image scanning speed in a sub-scan direction according to the image size change rate. A first calculating portion sets a window on image data of the oblique line pattern obtained through the reading unit, and calculates a center of gravity of the image data in the window. A controlling portion controls movement of the window according to a value of the center of gravity obtained through the first calculating portion. A second calculating portion obtains an image reading position error for each main scan line based on the value of the center of gravity and the image size change rate.
