ABSTRACT:
A photographic printer has a image taking means such as a color TV camera which takes an image of each picture of a roll of film which includes different sizes of pictures such as 35 mm full-size and 35 mm half-size picture frames to provide image signals, and a memory for storing the image signals. The image signals are read from the memory and displayed as a negative image in the form of a brightness pattern on a display such as CRT. Image signals for a half-size picture are read out from the memory in a direction perpendicular to that in which image signals of a full-size picture are read out, and interpolated so as to display a negative image magnified as large as an image of a full-size picture.
