ABSTRACT:
Apparatus and method are disclosed for automatic printing of an enlarged reproduction of an image frame stored on a microfilm without reproduction of images found on adjacent image frames and without the need to reposition the image frame adjacent frame marks found on a display screen. The method and apparatus of the invention provide for automatic calculation of the distance between the top of the image and the upper frame marks on the apparatus' display screen and the distance between the leading edges of the image frame to be reproduced and an adjacent image frame. In response to these calculations, an enlarged reproduction is produced that excludes information from adjacent image frames even though the image reproduced is of relatively short length compared to the copy sheet it is printed upon.
