摘要： Pages of books are copied without distortion due to curvature of the page near the book binding or the distortion in a copied page is corrected using the spacing of equidistant bars on tape strips applied to the top and bottom edges of a page before copying. The tape is preferably transparent and rather narrow and easily attached to a page to be copied. The first step in the distortion correction procedure is to locate the bars at the top and bottom of the page. The distortion of the spacing between the imaged bars is computed based on the known distance between the equidistant bars. The computed distortion of the spacing is then input to a distortion correction algorithm. The output of the distortion correction algorithm generates a corrected image. This image may also optionally delete the bars so that they are not printed in the copy. The corrected image is then copied.

摘要： A light source calibration target has a surface in view of a camera of an image capture system, The target includes a substrate having a substantially Lambertian surface, a visually distinct polygonal shape having corners formed on said surface so as to be visually distinct from the surface, and a plurality of objects each having an upstanding tip mounted on the surface, A method of using the calibration target operates, for each of the light sources to be calibrated, to capture an image of the target; process the captured image to derive light source calibration data and to store the calibration data.
