Abstract
A microfilm camera of the continuous type in which both the document and the film move continuously during filming, includes means whereby a user operator enters a desired optical reduction ratio into the keyboard of a main or host computer associated with the microfilm camera. The main computer, through appropriate communication with a microcomputer, automatically selects a lens of the appropriate focal length corresponding to the optical reduction ratio selected, and automatically establishes the correct film transport speed in accordance with the requested reduction ratio so that the relationship between the fixed transport speed of the document and the adjusted transport speed of the film causes the film image to have the same magnification ratio in the direction of movement as it has in the transverse direction. The provision of the appropriate lens and the adjustment of the film speed are accomplished by respective motors controlled by the mcicroprocessor. Accordingly, time-consuming manual selection of the appropriate lens and the corresponding manual adjustment of the film transport speed are eliminated.
