MULTIPLE-ORIENTATION IMAGE DEFECT DETECTION AND CORRECTION

摘要

A method, system, and computer readable medium are disclosed for detecting and removing defects using images captured at multiple orientations. Defects in a physical medium in which an image is formed can hamper attempts to record representations of the original image. To lessen the effects of these physical defects on captured images, multiple images are captured using multiple different orientations of the physical medium in which the image is formed. The physical defects obscure different image information when viewed from different angles. By capturing images at multiple orientations and combining these images, almost all of the desired image information from the original image can be recovered, despite imperfections in the physical medium. The present invention finds application in image capturing devices, such as flatbed scanners, photocopiers, and the like.
