摘要： An image processing apparatus determines a direction of document placement relative to a scanning direction based on a direction of a shadow region in an input image when a line sensor having a light receiving element performs a scan and an image read from a book document by a reading apparatus is input. When the direction of the binding portion of the document is determined to be along a longitudinal direction of the line sensor, an image of a region read by the light receiving element of the line sensor from reflected light undergoing specular reflection from the document is detected based on the amount of variation in luminance between adjacent pixels in the read image of the book document. Luminance of the image corresponding to the region is corrected.

摘要： In continuous printing of plural sheets of recording paper, a controlling section of an image forming apparatus corrects a writing position for a first sheet of recording paper in accordance with an off-center amount detected by a carrying position sensor with respect to the first sheet of recording paper. As for an nth sheet of recording paper, the controlling section corrects the writing position for the nth sheet of recording paper in accordance with an off-center amount α(n−1) detected by the carrying position sensor with respect to an (n−1)th sheet of recording paper. In a case where an absolute value of a difference between an off-center amount αn detected by the carrying position sensor with respect to the nth sheet of recording paper and the off-center amount α(n−1) exceeds a threshold, the controlling section corrects the writing position in accordance with the off-center amount αn and causes an exposure unit to write again the electrostatic latent image at the writing position corrected in accordance with the off-center amount αn, instead of writing an electrostatic latent image at the writing position corrected in accordance with the off-center amount α(n−1). This makes it possible to minimize a decrease in printing speed and improve accuracy of a position with which an image is formed on a sheet of recording paper.

摘要： A method for measuring dimensions between selected points on a side of interest in objects selected for measurement by an optical measuring system comprising a flatbed scanner and a connected computer system through acquiring a reference image to provide corresponding image distance errors; and also acquiring a measurement object image. Deviation curves are provided as the basis for determining deviation errors in the measurement object image. Corrected measurement object image distances are formed through combining the deviation errors in the measurement object image distances with the corresponding measurement object image. These corrected measurement object image distances are used to determine distances between chosen pairs of those selected locations.
