ABSTRACT:
A film image retrieval and scanning apparatus having split first and second optical paths with each optical path being precisely aligned with the other, and each path containing coupled zoom optics. The first path projects a film image onto a first scanner array in the first path to provide a real time display of the image on a TV monitor. The second optical path projects an image onto a second scanner array, which may have a higher resolution than the first array to provide an analog signal that is converted to a digital signal of the image that may be stored, or transmitted on a network, or both. The first scanner provides a real time image and serves as a viewfinder that can be used to locate the proper position of an image; thus ensuring that the image will be aligned with the second array so that it can be scanned by the second scanner array when desired.
