Document imaging system with bi-directional anamorphic magnification capability |
摘要 |
An imaging system in a copier is modified so as to scan original documents at speeds differing from the image medium speed through the exposure zone so as to anamorphically reduce or enlarge the projected image. A two process scanning operation results in an output image reduced or enlarged in two dimensions. Resolution is maintained by forming an effective imaging width of approximately 1 mm by using a combination of a lens array providing a narrow irradiance profile with an optically aligned slit of smaller width. Magnification values of from 0.50 to 1.5 are thereby enabled.
