    Abstract: A flow camera equipped with a microprocessor based control system accepts large original documents (22) in continuous, moving fashion and photographs them through a specifically shaped slotted aperture (182, 186) positioned between the original document (22) and an objective lens (190). The originals are illuminated during exposure simultaneously from the front and the back, recording congruent images from two-sided material such as engineering drawings on transluscent media having positionally related information on both sides. The light from the underneath side, opposite the lens (190) not only reveals and exposes the image on the second side but it enhances the quality and sharpness of the primary image on the side towards the lens. Avoidance of image loss is accomplished by using in the optical system a single mirror (188) which deflects the optical path substantially less than 90 DEG . Servomotors with encoder feedback are correlated by the microprocessor to the degree of photographic reduction so that the ratio of speed between the original document (22) and the moving strand of film is exactly equal to the reduction ratio to avoid speed induced distorsion in the reduced and enhanced film image.

    Abstract: A flow camera apparatus (10) operable for photographing large original documents in continuous, moving fashion includes a camera (74) located within the housing (12). An aperture adjustment mechanism (86) allows adjustment of the camera aperture from the outside of the housing (12) without opening the housing (12). The iris adjustment mechanism also allows the aperture to be changed during photographing of a document. The apparatus includes lamps (214, 216 and 218) for illuminating the document during photographing and a "T" mask assembly (22) provided with baffles (204 and 208) for allowing only light reflected from the document to enter the image path (88) to the camera (74). The apparatus (10) also includes precisely balanced detectors (126) for detecting entry of a document into the apparatus (10).

    Abstract: An apparatus for digitally archiving analog film images includes a support surface (58) on which an analog film image may be supported, and a digitizer (92) that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light (84) transilluminates the film image and projects it toward the digitizer through an objective lens (94) 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.
