Abstract

Apparatus for digitizing images (1) includes a reader device (3), such as a CCD array, having a photo-sensitive surface (4) that comprises a large number of pixels arrayed longitudinally and laterally. The reader device (3) is subjected to a ninety degree rotation and/or linear displacement by a distance of several pixels, as necessary, before and/or during the digitization process so as to provide optimum digital resolution for a variety of image formats.
