Abstract
A method for reproducing a color picture for use in a picture reproducing machine in which picture and recording cylinders are rotated at a certain rotation speed ratio, and pickup and exposure heads are moved in the direction of the cylinders' axis at a certain moving speed ratio, and in which picture signals picked up by scanning an original picture mounted to the picture cylinder are first stored in a memory and then are consecutively read out of the memory in synchronization with the rotation of the recording cylinder. Recording signals are composed from one scanning period of picture signals and the following scanning period of picture signals when the one scanning period of picture signals stored in the memory are skipped, and then thus obtained recording signals are fed to the exposure head.
