Abstract

PURPOSE: To make it possible to form a printing plate of good image quality by reading out the scanning line signal as specified from a frame memory synchronously with the scanning speed of a photoengraving scanner.
CONSTITUTION: The scanning line signal of two fields is read out synchronously with the scanning speed of a scanner 18 from a frame memory 5 which stores the video signal of one frame selected from a VTR 2. This signal is stored in a 1H memory 25 by way of a switching circuit 9. Here, the switching circuit is controlled by a gate signal generating circuit 13, by which the order of the scanning line signal to be stored in the memory 25 is regularized. Next, the signal read out from the memory 25 is color-separated as specified and is supplied to the scanner 18. It is also possible to form the scanning line signal for the other field by reading out an even or odd number of scanning line signals for one field and interpolating their mean values. In this way, the printing plate of good image quality may be obtained.
