Abstract
Abstract The invention relates to the making of reproductions of microfilm images which are scanned line-by-line using photoelectronic devices. The subsequent generation of images are reproduced onto photosensitive material line-by-line. By processing the video signal generated by scanning the first or original image, a series of parameters are produced which are stored either on the film or in a separate location. The second generation image is electronically scanned and the video signal processed to provide a second series of parameters. The first and second series of parameters are compared to provide an adjustment signal. The adjustment signal is then used to change or alter the second video signal prior to it being used to electronically reproduce the second generation image on film. The stored series of video parameters are used to produce subsequent generations of film images in a like manner.
