ABSTRACT:
An apparatus for digitally archiving analog film images includes a support surface on which an analog film image may be supported, and a digitizer that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light transilluminates the film image and projects it toward the digitizer through an objective lens which focuses the image. The positions of the digitizer and the lens along the Z axis are adjustable so that the size of the image projected onto the digitizing means can be varied. For example, it is possible to move the digitizer and objective lens between a range of enlarging positions in which the lens is closer to the film image than to the digitizer, and a range of reducing positions in which the lens is further from the film image than from the digitizer so that the film image may be either enlarged, reduced or reproduced at the same size before being sensed and converted into digital data.
