ABSTRACT:
A method of making a large size print from an original by dividing an image of an original into smaller divisions in the form of a matrix is provided. Video signals of the original image are read from divided memory areas of a memory, respectively. The information in each of the smaller divisions are enlarged by interpolating the video signals read out from each divided memory area. The interpolated video signals of each smaller division are displayed on an image display device such as CRT and projected onto a photographic paper for exposure, thereby making enlarged prints of the smaller divisions which in turn are arranged to form an enlarged picture of the original.
