ABSTRACT:
Trimming prints are made from a plurality of image frames in photographic film, in order of trimming magnification, by reading out trimming magnification data for each frame as well as frame position data used for positioning each frame. The adjustment of the focal length of a zoom lens is effected in the order changed following the order of the trimming magnification so as to make a series of prints in the shortest time. In accordance with a preferred embodiment of the invention, frames are printed in the order of the permutation, yielding the shortest processing time in rearrangement of the sequential frames. Therefore, efficiency is improved greatly in shifting the frames and adjusting the focal length of the zoom lens.
