Abstract
Abstract The image converting system including an image input step or apparatus for converting an original document information into electric image signals an inputting them, an image processing step or apparatus for processing the original document information supplied by the image input step in a predetermined process or order to provide converted image signals different from the original image, and a recording step or apparatus for recording the image on a recording medium in accordance with the image signals derived from the image processing step thereby recording a pattern materially different from the original image on the recording medium or displaying same on an indicator. The converted image signals may be obtained by the use of a coding or scrambling signal and an Exclusive OR operation. Line shifting may be employed. The original image may also be divided into a number of grid components and mixed in accordance with the coding rule.
